Love for a Pet

February 14, 2025 by suzannesmom

For Valentine’s Day this year I thought I would post about the love people have for pets. The article I found at Yale University’s human relations website is a little research-y, but it shows just how far back in history humans have felt that kind of love.

“The human love of pets is a powerful and global phenomenon. For many pet owners, their furry (or scaly) domestic companions transcend any simple categorization of non-human animal. Indeed, research shows that it is a growing global trend for pet owners to consider their animals to be full members of their families; to dote upon them as they would children or romantic partners, both emotionally and financially; and to thereby develop strong bonds of dependency, love, and support.

“Gray and Young (2011) conducted a broad cross-cultural study of human–pet dynamics around the world utilizing … a stratified random sample of 60 culturally, linguistically, and geographically diverse societies represented in eHRAF [Human Relations Area Files] World Cultures. Their study revealed that ‘dogs, birds, and cats were the most common pets, followed by horses, other hoofed mammals such as water buffalo, rodents, nonhuman primates, and pigs.’ … Attitudes and sentiments towards the domesticated animals vary, with many societies attaching spiritual meaning to their birds, cats, or dogs. …

“The emotional connection between pets and their owners is worthy of cross-cultural attention. For example, it has been discovered that dogs are able to read emotional cues from the faces of their owners and to respond accordingly. Other recent studies have shown that people tend to have more compassion for animals who are suffering than for adult humans in similar circumstances, treating the hurt dogs akin to helpless infants who need protection. Based on global data, researchers in this telling social experiment concluded that, by and large, subjects ‘did not view their dogs as animals, but rather as “fur babies” or family members alongside human children.’

“As to the origins of human-pet relationships, anthropologists suggest that our propensity for keeping pets, as well as our finely honed empathy for their emotional state, stems from the process of animal domestication in early human history, beginning with dogs and continuing to horses, sheep, goats, and others:

” ‘In each case, humans had to learn to put themselves in the minds of these creatures in order to get them to do our bidding. In this way our senses of empathy and understanding, both with animals and with members of own species, were enhanced. Our special relationship with animals is revealed today through our desire to have pets (McKie 2011).’ …

“Evidence of ancient burials from eHRAF Archaeology supports recognition of a longstanding bond between humans and animals far back into prehistory. For example, in ancient Egypt (5000-2000 BCE), Rice finds that, ‘amongst the graves at Helwan are examples of the burials of dogs and donkeys; as these do not seem to be the subject of cult or religious observance, it may be that they were family pets, since the Egyptians always kept animals about them, as members of their households’ (1990: 131). Similarly, on the other side of the world, the purposeful interment of animals in prehistoric settlements is known throughout the American Southwest and northern Mexico. According to Woosley and McIntyre, at the Wind Mountain site in New Mexico dating back to 2000-600 BP, the animals buried included dogs, bears, turkey, golden eagles, hawks, mourning doves, and scarlet macaws (1996: 281).

“Edmund Leach’s seminal work, Animal Categories and Verbal Abuse (1964), presents the human relationship to animals in terms of social distance. Attitudes towards different animals reflect our familiarity with them, so that the most familiar or ‘closest’ to ourselves are subject to ritual provisions or prohibitions because they are considered ‘taboo.’ They are also most worthy of human-like care and devotion. This is why people generally avoid eating the animals that they might also keep in their homes as pets. …

“The dynamic of intimacy in the human relationship to animals recurs in the ethnographic literature. The closeness of human-animal relationships is evident around the world with instances of beloved species being cared for as fondly and tenderly as human babies.”

Linguist as Crime Fighter

February 13, 2025 by suzannesmom

Image: The Dial.

I read a lot of murder mysteries. They are not the only type of book I like, but I like the puzzles and sometimes even the writing. So I was drawn to today’s article on the emergence of an unlikely crew that has gotten involved in solving tough cases.

Julia Webster Ayuso wrote recently at the Dial about forensic linguists.

“On the evening of October 16, 1984, the body of four-year-old Grégory Villemin was pulled out of the Vologne river in Eastern France. The little boy had disappeared from the front garden of his home in Lépanges-sur-Vologne earlier that afternoon. His mother had searched desperately all over the small village, but nobody had seen him.

“It quickly became clear that his death wasn’t a tragic accident. The boy’s hands and feet had been tied with string, and the family had received several threatening letters and voicemails before he disappeared. The following day, another letter was sent to the boy’s father, Jean-Marie Villemin. ‘I hope you will die of grief, boss,’ it read in messy, joined-up handwriting. ‘Your money will not bring your son back. This is my revenge, you bastard.’

“It was the beginning of what would become France’s best-known unsolved murder case. The case has been reopened several times, and multiple suspects have been arrested. Grégory’s mother, Christine, was charged with the crime and briefly jailed but later acquitted. Jean-Marie also served prison time after he shot dead his cousin Bernard Laroche, who had emerged as a prime suspect. …

“More than three decades after Grégory’s murder, police brought in a team of Swiss linguists from a company called OrphAnalytics to examine the letters and their use of vocabulary, spelling and sentence structure. Their report, submitted in 2020, and part of which was leaked to the press, pointed to Grégory’s great-aunt, Jacqueline Jacob. The results echoed earlier handwriting and linguistic analysis that had led to Jacob and her husband’s arrest in 2017. (The couple was freed later that year over procedural issues.)

“While the new evidence has not yet been presented in court, some believe it could help to solve the case that has haunted an entire generation. It has also shone a spotlight on the little-known field of forensic linguistics. In France, the use of stylometry — the study of variations in literary styles — has largely been confined to academic circles. The Grégory case is the first time it has been applied in a major criminal investigation.

“The use of forensic linguistics in the case was initially treated with skepticism. … The general prosecutor at the Court of Appeal of Dijon, Philippe Astruc … cautioned: ‘To imagine that it will suddenly be settled with a single report is an illusion.’

“ ‘The press didn’t understand it, and the lawyers are saying it can’t work,’ Claude-Alain Roten, CEO of Orphanalytics, told me over the phone from his office in Vevey, a Swiss town on Lac Léman. But he assured me his results are reliable. ‘We came to similar conclusions to the conclusions they had already reached by other means,’ he said, adding that OrphAnalytics last year completed another report commissioned by the general prosecutor of Dijon, who oversees the Villemin investigation, analyzing an additional anonymous letter. ‘It gives us a very precise idea of who the person who wrote the letter is.’

“According to forensic linguists, we all use language in a uniquely identifiable way that can be as incriminating as a fingerprint. … The term ‘forensic linguistics’ was likely coined in the 1960s by Jan Svartvik, a Swedish linguist who re-examined the controversial case of Timothy John Evans, a Welshman who was wrongfully accused of murdering his wife and daughter and was convicted and hanged in 1950. Svartvik found that it was unlikely that Evans, who was illiterate, had written the most damning parts of his confession, which had been transcribed by police and likely tampered with. The real murderer was the Evans’ downstairs neighbor, who turned out to be a serial killer.

“Today, the field is perhaps still best known for its role in solving the ‘Unabomber’ case in the United States. Between 1978 and 1995, a mysterious figure sent letter bombs to academics, businessmen and random civilians, killing three people and injuring at least 24. The lone bomber was careful not to leave any fingerprints or DNA traces, evading the authorities for 17 years and triggering one of the longest and most expensive criminal investigations in U.S. history. But in 1995, he made a crucial mistake. He told the police he would pause his attacks on the condition that a newspaper publish his 35,000-word anti-technology manifesto.

“When the document appeared in the Washington Post, the New York Times and Penthouse magazine, several people — including the perpetrator’s brother— reached out to say they recognized the writing style. Meanwhile, FBI linguist James Fitzgerald and sociolinguist Roger Shuy, who had been studying the bomber’s letters, had identified patterns in his language that helped narrow the list of suspects: Spellings such as ‘wilfully for ‘willfully’ and ‘clew’ for ‘clue’ pointed to someone from the Chicago area, for example. Eventually, the linguistic evidence was strong enough to issue a search warrant for the home of a reclusive mathematician named Theodore Kaczynski, raised in Chicago but living in rural Montana, where investigators found copies of the manifesto and homemade bombs. …

“At OrphAnalytics, Roten, who has a PhD in microbiology, explains that algorithms identify patterns in syntax much like in a DNA sequence. The difference, he tells me, is ‘there are very few errors in genome sequences, which is not the case when we compare texts,’ he said. Unlike with DNA, which a perpetrator can’t control, the author of a poison-pen letter is likely to try to obscure his writing style, for example by trying to sound less educated or to seem foreign.

“Still, linguists argue that style is almost impossible to hide because many of the choices we make are unconscious. Someone may decide to spell a word wrong, but forget to modify less noticeable details, such as their use of punctuation. ‘People say a lot about themselves when they’re trying to hide their writing,’ said Roten.”

Why Orcas Are Returning

February 12, 2025 by suzannesmom

Photo: Jules Struck.
Jim Borrowman was part of a successful lobby to create an ecological reserve in western Canada’s Johnstone Strait in the 1980s.

Today’s story is about a few people whose determination helped to reverse the decline of a group of Orca whales — people who just don’t give up.

At the Christian Science Monitor, Jules Struck wrote recently about their work.

“Jim Borrowman cut the engine of the Nisku in the gray water of the Johnstone Strait, relinquishing his boat to an eastbound tide. He unraveled the line of a hydrophone – a cylindrical, underwater microphone – and dropped it portside.

“On the other end of the cord a pint-size Honeytone speaker in the cabin broadcast a conversation from the deep: the ethereal, two-toned call of an orca whale to her clan.

“ ‘I think they’re what we call “A1s,” ‘ said Mr. Borrowman, browsing a database of local orcas on his phone.

“Mr. Borrowman has been watching, and watching over, these whales for decades. He was one in a band of Vancouver Islanders who successfully lobbied in the early 1980s to set aside a protected area for Northern resident orcas, which lost a third of their population to hunting and capture in the 1950s and ’60s.

“This early act of ocean preservation laid a foundation from which decades of important research – and a deep local allegiance to the whales – have flourished. Galvanized by this data, environmentalists and First Nations just won a battle to evict commercial open-net fish farms from the area, which compete with the orcas’ food supply.

“With early signs of abundant salmon, and a small but decades-long uptick in Northern resident population numbers, it feels to some like nature rallying.

“ ‘You can see the whales coming back,’ says Alexandra Morton, an author and marine biologist who has studied salmon in the Johnstone Strait since the 1980s. She was part of a group that occupied a Vancouver Island fish farm in 2017 in protest of the industry.

“The A1s spotted by Mr. Borrowman from the bow of the Nisku are one pod of one type of orca, called Northern resident killer whales, which number some 400 and live along the coast of British Columbia.

“They’re doing particularly well, and have been growing by a handful of members each year since the ’70s. Northern residents are the most reliable visitors to the Robson Bight (Michael Bigg) Ecological Reserve, where Mr. Borrowman has served as a warden and run a whale-watching tour business with his wife, Mary, for decades until recently retiring.

“ ‘This is a beautiful, sensitive estuary at the terminus of a 100,000-acre watershed, the last untouched one on the east coast of Vancouver Island at the time,’ he says.

“It’s unique for another reason. At two known beaches at the mouth of the Tsitika River, Northern resident orcas rub gracefully along the seafloor pebbles in what scientists have dubbed a unique ‘cultural behavior.’

“It was this behavior, first captured in underwater footage by Robin Morton, Alexandra Morton’s late husband, that convinced the public, the press, and finally the federal government to set aside about 3,000 acres of water plus shore buffer as a protected area closed to boat traffic.

“Today, volunteer wardens with the Cetus Research & Conservation Society Straitwatch program monitor the reserve and gather population data on the whales and their pods. …

“Today, the whales’ major issues are food scarcity, noise, and chemicals in the water. But if the threats to orcas have become more complex, the responses have grown increasingly well-informed by a bedrock of research, much of which has come out of the ecological reserve and its orbit. …

“Decades of research have since shown that major pathogens and lice leak from [salmon] farms’ huge, suspended net pens straight into the paths of migrating salmon, ravaging their thin-skinned young and immobilizing the adults.

“Pacific salmon are also an important food source and cultural pillar for First Nations. They are intricately linked to the ecosystem, and scientists have even tracked nutrients from decomposed salmon high into the mountains.

“Ms. Morton campaigned for decades to close the fish farms. Nothing changed until she and Hereditary Chief Ernest Alexander Alfred, with a group of other First Nations people, peacefully occupied a Vancouver Island salmon farm owned by Marine Harvest.

“That protest led to a 2018 agreement with the British Columbia government requiring the consent of three First Nations – ‘Namgis, Kwikwasut’inuxw Haxwa’mis, and Mamalilikulla – for fish farms to operate around Vancouver Island.

“First Nations closed more than a dozen salmon farms in and near the strait. Then, the federal government announced it would ban all open-net farms in British Columbia by 2029.

“The decision is not universally supported by First Nations along the coast: 17 have agreements with salmon farming companies, which collectively employ around 270 Indigenous people, according to the Coalition of First Nations for Finfish Stewardship. Overall, open-net salmon farming accounts for 4,690 jobs and $447 million in gross domestic product across Canada, according to the BC Salmon Farmers Association.

“But for many, it was a turning point. Coho and especially Chinook salmon stocks spiked this year in Vancouver Island and its inlets, according to the Pacific Salmon Foundation, after years of downturn.”

Bogs Become Wetlands Once More

February 11, 2025 by suzannesmom

Workers harvest cranberries at the Rocky Meadow bog in Middleborough, Massachusetts, ahead of Thanksgiving. 

Recently, I read about a federal program paying “farmers to convert the land of bogs that is not efficient for growing” into wetlands that can alleviate climate change consequences. Whether or not the federal program will continue, Massachusetts is on the case, helping its own farmers with restoration.

Gloria Oladipo wrote at the Guardian last November, “As millions of cranberries were being harvested for Thursday’s US Thanksgiving holiday, Massachusetts farmers were working to convert defunct cranberry bogs back to wild wetlands, amid climate crisis woes. Several restoration projects were awarded $6m in grants to carry out such initiatives, state officials announced this week.

“The grants, provided by the New England state’s department of fish and game division of ecological restoration (DER), will ‘increase resilience to climate change for people and nature, restore crucial wildlife habitat, and improve water quality’ in 12 communities, said the Massachusetts governor, Maura Healey, in a statement. …

“ ‘These initiatives will enhance our ability to store and sequester carbon with nature and help us meet our net zero goals,’ said Rebecca Tepper, secretary of the state’s office of energy and environmental affairs. …

“The grants are being awarded through two state programs: the DER’s wetland restoration program and the DER’s cranberry bog restoration program, which converts defunct cranberry bogs into wetlands and streams.

“To date, scientists and government officials have converted 400 acres of retired cranberry bogs into wetlands, the Washington Post reported. State officials have said they hope to restore an additional 1,000 acres of bogs within the next decade. …

“As sea levels rise in Massachusetts because of the climate crisis caused by humans burning fossil fuels, scientists are looking to develop bogs into wetlands to improve coastal resilience and slow down erosion.

“Wetlands can hold more water and filter out pollutants amid increased storms that bring potential flooding. They also have other environmental benefits, acting as wildlife habitats and storing carbon dioxide from the atmosphere in their soil.

“More farmers have been drawn to the prospect of transitioning their former cranberry bogs into wetlands. The climate crisis and economic factors, including the high cost of modernizing bogs, can make cranberry farming more difficult. …

“ ‘We are in an upward trend in terms of interest in retiring cranberry bogs,’ said Brian Wick, executive director of the Cape Cod Cranberry Growers Association, to the Post. … But getting land for restoration remains a competitive process, as other businesses – such as housing developers – vie for undeveloped coastal land.

“ ‘This opportunity won’t be here in 25 years,’ said Christopher Neill, a senior scientist at the Woodwell Climate Research Center and an expert in restored bogs, to the Post. ‘These growers are not going to hang on, they’re going to make decisions and the land won’t be available forever.’

“While conservation projects have steadily increased in southeastern Massachusetts, restoration initiatives are still relatively new. The majority of finished projects are only a few years old, with 14 restoration initiatives still being designed and implemented, the Post reported.”

In addition to benefits like carbon storage and habitat for wildlife, converted cranberry bogs can be lovely for walkers.

Small, Important Steps

February 10, 2025 by suzannesmom

These highway drainage pipes send water directly toward homes in Shiloh, Alabama — homes  that Black landowners have maintained since the Reconstruction era. Other neighborhoods benefit from drainage that runs parallel to roadways.

“Climate injustice” is not a term favored by the billionaire class, but removing out-of-favor words doesn’t make the realities they represent go away. Whether injustices occur on purpose or by accident, they happen. But around the world, ordinary people do what they can to fight back.

Paloma Beltran, associate producer of environmental radio show Living on Earth, has written that recent government decisions “will have a ripple effect across communities that have been pushing back against the impacts of industrial pollution for years. On this week’s show, we spoke with Patrice Simms, the Vice President of Litigation for Healthy Communities at Earthjustice, about the federal government’s role in protecting people from environmental discrimination. … Here’s some of what he said:

“ ‘Really significantly for me, what continues to motivate me is my tremendous respect and appreciation for the people on the front lines of pollution and exposures. I work really closely with communities across the country who are in very real ways, fighting for their lives, fighting for their families, fighting for their well-being, and fighting for their communities. And these aren’t people who are getting paid to do this. These are people who are doing this because they have to. They’re doing this because they’re watching their children get sick. They’re doing this because they’re watching their communities die. And there’s nothing more motivating than understanding and knowing the members of these communities. … It’s an honor and a privilege to get to work with them and beside them and for them, and that keeps me going every day.’

“So it feels like an opportune time to highlight a few environmental justice leaders who have shared their stories with us:

  • “Sharon Lavigne is a former school teacher who has become a fierce environmental defender out of love for her community. She’s from Cancer Alley, an eighty-five-mile stretch of the Mississippi River, from Baton Rouge to New Orleans. Slave plantations once lined this part of the river, and many descendants of former slaves still reside in that area. In the 1960s, petrochemical plants began flooding the area, in part due to the river allowing trade, transportation and the disposal of waste in an unseen and cheap way. Most of these plants are in close proximity to predominantly Black communities, exposing them to toxic emissions. According to a 2023 study published in Environmental Challenges, toxic emissions in Louisiana are 7 to 21 times higher in communities of color compared to white communities, and chemical manufacturing is the largest contributor to this disparity. Sharon Lavigne … co-founded Rise St. James, a faith-based grassroots organization fighting against the proliferation of chemical industries in St. James Parish, Louisiana. In 2021, Sharon won the prestigious Goldman Environmental Prize for her activism. For more, take a listen to our conversation. ….
     
  • “Nalleli Cobo grew up within 30 feet of an oil well — one of more than 5,000 oil and gas wells across Los Angeles, California, 700 of which are currently active. Like much of her community, Nalleli suffered from chronic headaches, nosebleeds, stomach pain, and asthma, and at the age of 19, she was diagnosed with cancer. Following treatment, Nalleli is now cancer free, but unable to have children. In March 2020, she joined a coalition of environmental justice organizations and successfully sued the city of Los Angeles for environmental racism and violation of CEQA, which is the California Environmental Quality Act. AllenCo Energy was forced to close down its well located near Nalleli’s home. … Tune into my interview with her here.
     
  • “Andrea Viduarre is another environmental justice advocate who organized her community and convinced the California Air Resources Board to adopt transportation regulations that limit trucking and rail emissions. (However, the state withdrew these rules [after the 2024 presidential election.] Southern California’s Inland Empire serves as a the hub for logistical infrastructure and is home to a predominantly Latino population. A staggering 40% of all US goods move through the area, a lot of which is transported through diesel trucks which emit toxic pollutants linked to cancer, asthma and premature death. Andrea Viduarre’s work has made huge strides in getting pollution out of her community. … You can learn more about in our discussion here.
     
  • “Robert Bullard is known to many as the father of environmental justice. He ran the first study on eco racism in 1979, and found that toxic facilities in Texas were disproportionately located in Black communities. His research was used in the Bean v. Southwestern Waste Management Corporation lawsuit, the first case to use civil rights law to challenge environmental racism. He’s the founding director of the Bullard Center for Environmental and Climate Justice, as well as Distinguished Professor of Urban Planning and Environmental Policy at Texas Southern University. He’s been advocating on behalf of the predominantly Black community of Shiloh, Alabama, whose homes have been repeatedly flooded since a nearby highway was widened in 2018. Dr. Bullard joined us back in 2024 to talk about this case.”

It has always lifted my spirits to see everyday people doing what they can where they are. Public radio’s environmental show Living on Earth will lift your spirits.

Home Remedies

February 9, 2025 by suzannesmom

It’s amazing how many cultures use lemon and ginger tea to treat colds.

I have volunteered as an English as a Second Language (ESL) assistant for about eight years. Recently Teacher Allissa’s assignment for her students was to write about the home remedies their families use. These are adult students from countries as diverse as Turkey, the Dominican Republic, Afghanistan, Peru, China, Haiti, Cambodia, Guatemala …

Note the cold remedy mentioned most.

“When my children have a fever, I put them in the bathtub with warm water, salt and vinegar. It’s so good to lower the fever.”

“When someone is sick, I boil chamomile tea for them. I also make lentil soup or chicken soup.”

“In my country, when a person is sick, l give them some tea, some vegetable oil, soup and cinnamon tea.”

“I treated the children’s colds with tea with raspberry and lemon, and also tea with ginger, honey and lemon. For colds and viruses, the best noodle soup in chicken broth is served with a garlic yogurt mixture. Tasty and healthy for cough. In my country, Azerbaijan, many herbs grow in the mountains for various diseases.”

“Lemon tea is good for cough.”

“In China, we always think ginger tea can help people keep away colds.”

“Lemon tea is helpful to keep your immune system strong. Lemon contains vitamin C. Make sure to wear a hat, gloves, and a scarf if you’re going outside to stay comfortable.”

“I remember when I was in Haiti and had a sore throat, my mother used to boil ginger and lemon tea. Then when it was ready, she put honey in it. Then she gave me the tea to drink, and after a while I felt better.”

“Lemon is good for the people who are sick. For example, if they have a sore throat or are losing their voice. I make a lemon syrup with hot water and salt and keep it for one year. If you keep it more then a year, it’s no good. When you are sick, boil it with the water and drink it. The next day you will feel better.”

“When I have a cold, I prefer to drink lemon tea with honey. It is very useful for sore throat and runny nose. I also take anise tea for any stomach disorders.”

“I remember when I was a little girl and my mother would put limes with salt on my wrists and feet to help lower down my body temperature when I was sick. I’m really grateful that she taught me this because I now use this method to help cure my kids when they’re sick.”

“Lemon tea is very good for your body, especially when you have a fever and sore throat. When I have a fever, I drink it and it helps me. I advise you always to drink lemon tea.”

“Mint is a relaxing plant. When I have a stomach ache, I make mint with lemon tea. Oregano is the best herb with a roast chicken. Lavender is a miracle plant for me. It’s for detoxing, good sleep and headaches.”

“We treat colds with hot tea with ginger, lemon and honey. Prepare hot chicken broth soup with noodles and add garlic.”

“In Peru when we are sick with cough and fever, we drink hot water, a fresh eucalyptus leaf and also chamomile and a small piece of ginger, and we sweeten it with honey. We also rub our chest and back with Vicks VapoRub, and at night before sleeping, we place a slice of onion under the soles of our feet and put on our socks. The next day we take out the slice of onion, and the onion is all black and it is thrown in the trash, because it has already absorbed part of the cold. The onion strengthens our immune system. You can also place half an onion on top of the nightstand. The smell of the onion absorbs the flu viruses that are in our bedroom; it also serves to relieve asthma and helps the respiratory tract.”

I shared the onion idea with my 12-year-old granddaughter when she had flu last week. She didn’t try it.

Please share your own home remedies.

A Powder That Stores Carbon

February 8, 2025 by suzannesmom

A carbon-capturing powder, pictured on Berkeley’s campus. 

Somehow or other scientific research about global warming will continue. Today’s example comes from Berkeley in California.

At the Guardian, Katharine Gammon reports, “An innocuous yellow powder, created in a lab, could be a new way to combat the climate crisis by absorbing carbon from the air.

“Just half a pound of the stuff may remove as much carbon dioxide as a tree can, according to early tests. Once the carbon is absorbed by the powder, it can be released into safe storage or be used in industrial processes, like carbonizing drinks.

“ ‘This really addresses a major problem in the tech field, and it gives an opportunity now for us to scale it up and start using it,’ says Omar Yaghi, a chemist at the University of California, Berkeley. It’s not the first material to absorb carbon, but ‘it’s a quantum leap ahead [of other compounds] in terms of the durability of the material.’

“The powder is known as a covalent organic framework, with strong chemical bonds that pull gases out of the air. The material is both durable and porous, and can be used hundreds of times, making it superior to other materials used for carbon capture.

“Yaghi has been working on similar materials for decades. It’s part of a broader push to collect tiny amounts of carbon from the air – either from power plants or from air around cities. Yaghi’s research with Zihui Zhou, a graduate student in his lab, and others was published in the journal Nature. …

“Yaghi’s team tested the new powder and found that it could successfully absorb and release carbon more than 100 times. It fills up with carbon in about two hours, and then must be heated to release the gas before starting the process over again. It only requires a temperature of about 120F to release the carbon; that makes it an improvement over other methods, which require a much higher temperature.

“That feature means places that already produce extra heat – such as factories or power plants – could use it to release the gas and start the cycle again. The material could be incorporated into existing carbon capture systems or future technology.

“Yaghi … plans to scale the use of this type of carbon capture with his Irvine, California-based company, Atoco, and believes the powder can be manufactured in multi-ton quantities in less than a year.

“Shengqian Ma, a chemist at the University of North Texas who was not involved in the new work, says this technology could be gamechanging. ‘One longstanding challenge for direct air capture lies in the high regeneration temperatures,’ he says, adding that the new material can substantially reduce the energy needed to use direct air capture. …

“Says Farzan Kazemifar, a associate professor in the department of mechanical engineering at San Jose State University who was not involved in the new study, ‘In the short term, replacing large emitters of carbon dioxide – like coal power plants – with renewable electricity offers the fastest reduction in emissions. However, in the long term, in case the emissions don’t go down at the desired pace, or if global warming effects intensify, we may need to rely on technologies that can remove carbon dioxide from the atmosphere, and direct air capture is one of those technologies.’

“Still, removing carbon from the air remains difficult, and as with all early-stage lab-scale studies, the challenge is scaling up the system for pilot studies. … Any technology to capture the gas from the air requires moving huge volumes of air – and that requires large electricity consumption for running fans, says Kazemifar. …

“Some scientists worry that the expectations of direct air capture systems has been overly rosy. A group of scientists from MIT recently wrote a paper analyzing the assumptions of many climate stabilization plans, and pointing to ways that direct air capture may be overly optimistic.

“Ma also points out that a major challenge to using this approach to combat climate change lies in the high cost of materials for creating substances that capture carbon.

“Still, Yaghi says this material can change the way we address carbon removal. ‘This is something we’ve been working on for 15 years, that basically addresses some of the lingering problems,’ he says.”

Women in Construction Band Together

February 7, 2025 by suzannesmom

Photo: Riley Robinson/CSM.
Above, Lucy Lujana, a carpenter with United Brotherhood of Carpenters and Joiners Local 54 in Chicago. As of 2023, only 3.1% of carpenters were women. Sometimes they call themselves the “Sisters of the Brotherhood.”

In the US, some women have moved into jobs traditionally held by men, but progress seems slow to me. In countries including India, Australia, Finland, England, and Israel, women have served at the very top, same as being president in the US. America’s oddly progressive and backward character is something to ponder.

Today we consider women in unions.

Richard Mertens writes at the Christian Science Monitor, “Last year, Lisa Lujano, a longtime member of the United Brotherhood of Carpenters and Joiners Local 54, found herself in very unfamiliar company. She had been tasked to build stairs in one section of the Obama Presidential Center on Chicago’s South Side. When she showed up for work, she discovered she would be part of a crew of five, all women.

“ ‘I don’t know how it came about,’ Ms. Lujano says. … Most of the time, when she shows up for work, she’s the only woman on the crew. And she and her fellow tradeswomen know as well as anyone an inescapable truth: The American construction site is still a man’s world. Until that moment, at least, when suddenly it wasn’t.

“ ‘It was a good experience,’ Ms. Lujano says, looking back on the 11 months working alongside other women carpenters. ‘We were able to relate, be more comfortable with each other. Then she adds, almost exultingly, ‘We’re sisters in the brotherhood!’ …

“Ms. Lujano has been a member of her union for almost 25 years. The journeyman carpenter loves her work, the daily routine. But she still puts up with unpleasant conversations. At lunch she’ll sometimes sit by herself, or take a nap in her car. …

“On a recent Friday, she was … on a team of about 60 workers rebuilding a train station at the edge of the University of Illinois Chicago campus. She’s one of only five women at the site today, the only one on her crew of 10. …

“Over the past decade, the number of women in the construction sector of the U.S. economy has risen steadily, from about 800,000 in 2012 to about 1.3 million in 2023, according to the U.S. Bureau of Labor Statistics.

“Only 11% of jobs in construction industries are held by women, and the majority of these jobs are in office work, sales, or other support services. A growing number are even becoming managers. But on construction sites themselves, the vast majority of construction workers remain men. …

“ ‘The whole process of diversifying the construction trades has been an incredible slog,’ says Jayne Vellinga, executive director of Chicago Women in Trades, an organization that has worked for decades to help women find jobs in the skilled trades.

“[Yet] there’s been a surge in demand for construction workers. … About 94% of construction firms report being unable to hire the skilled workers they need, according to the Associated General Contractors, a trade group in Arlington, Virginia. Experts estimate this shortage numbers more than a half-million workers.

“Given these shortages, the contractors trade group also found last year that 77% of construction companies report that ‘diversifying the current workforce at our firm is critical to strengthening our future business.’

“This doesn’t mean companies will be hiring more women. There remains a significant cultural obstacle to bringing more women into and training them for the skilled trades: Construction is still widely believed to be the domain of men. …

“Like many women, Ms. Lujano followed an unconventional path into the trades. She had no family connections, no uncle or father to bring her into the business, as young men often had. She had dropped out of high school to care for a son who was just a year old. ‘I couldn’t support him,’ she says. …

“In 1998, she saw a flyer from Job Corps, a federal program that offers young people preapprenticeship training and a chance to finish high school. The flyer listed different jobs: plumber, electrician, carpenter, secretary, and more.

“She enrolled in a program in Golconda, a small Illinois town on the banks of the Ohio River. There, over 13 months, she earned a GED certificate and received hands-on training in how to build things. She and other students built ladders, bunk beds, and even frame houses. ‘It was just so cool,’ she says. ‘I ended up loving it.’

“But it wasn’t easy. In her first job she spent four months demolishing and rebuilding porches for a nonunion contractor. Then she got her first union job, working on a bridge in Skokie, just north of Chicago. She was the only woman in a crew of young men in their early 20s. The men would make vulgar comments to her, or about her, even in her presence. …

“Ms. Lujano is no longer a rookie apprentice, but a journeyman carpenter making the full journeyman’s wage: $55 an hour, plus health benefits and a pension. She’s also a union steward, responsible for making sure the workers are properly credentialed and helping them deal with complaints or problems on the job. …

“Looking out over the worksite at the train station in Chicago’s Near North Side, Ms. Lujano sees both good and bad, both progress and the limitations of that progress. Including her with the carpenters, there is one woman among the electricians, one among the ironworkers, one among the bricklayers, and one among the painters. Tradeswomen often feel they are only tokens of diversity on the job site. But to Ms. Lujano, one woman is better than none. …

“Now in her third decade as a union carpenter, she feels keenly the need to help younger women as they face the challenge of working in a world that has, for so long, been dominated by men.”

Will Cactus Pear Save Italy?

February 6, 2025 by suzannesmom

Photo: ItalianNotes.
Prickly pear, or cactus pear. When Italy suffers from drought, some people turn to an edible cactus.

A while ago I posted photos I’d taken in New England and was surprised to see a cactus this far north. Hannah called it “prickly pear” and told me it was known for its versatility. It’s apparently the same cactus that Italy is looking to as a reliable food source.

Stefano Bernabei and Gavin Jones write at Reuters, “Global warming, drought and plant disease pose a growing threat to agriculture in Italy’s arid south, but a startup founded by a former telecoms manager believes it has found a solution: Opuntia Ficus, better known as the cactus pear.

“Andrea Ortenzi saw the plant’s potential 20 years ago when working for Telecom Italia in Brazil, where it is widely used as animal feed. On returning to Italy he began looking at ways to turn his intuition into a business opportunity.

“He and four friends founded their company, called Wakonda, in 2021, and began buying land to plant the crop in the southern Puglia region where the traditionally dominant olive trees had been ravaged by an insect-borne disease called Xylella.

“The damage from the plant disease has been compounded by recurring droughts and extreme weather in the last few years all over Italy’s southern mainland and islands, hitting crops from grapes to citrus fruits.

“Ortenzi is convinced the hardy and versatile cactus pear, otherwise called the prickly pear or, in Italy, the Indian fig, can be a highly profitable solution yielding a raft of products such as soft drinks, flour, animal feed and biofuel. …

” ‘As an industry, cactus pear production is growing rather quickly, especially for fodder use and as a source of biofuel,’ said Makiko Taguchi, agricultural officer at the United Nations’ Food and Agriculture Organization headquartered in Rome.

“The cactus produces a tasty fruit eaten in much of Latin America and the Mediterranean, while in Mexico the flat green pads that form the arms of the cactus, are used in cooking. In Tunisia, where it covers around 12% of cultivated land, second only to olive trees, the cactus pear is a major source of income for thousands, particularly women who harvest and sell the fruit.

“In Brazil, which has the world’s largest production, it is mainly cultivated in the north-east for fodder, while Peru and Chile use it to extract a red dye known as Cochineal, used in food and cosmetic production.

Sportswear group Adidas and carmaker Toyota have recently shown interest in using the cactus to produce plant-based leather sourced mainly from Mexico.

“The cactus pear is not yet included in the FAO’s agricultural output statistics, but Taguchi cited the rapid expansion of CactusNet, a contact network of cactus researchers and businesses worldwide which she coordinates. …

“The plant, native to desert areas of south and north America, thrives in the increasingly arid conditions of Italy’s south, and needs ten times less water than maize, a comparable crop whose byproducts also include animal feed and methane. …

“Of the roughly 100,000 hectares of olive trees destroyed by Xylella in southern Puglia, only 30,000 will be replanted in the same way, [Ortenzi] told Reuters in an interview. ‘Potentially 70,000 could be planted with prickly pears,’ he said. …

“Wakonda’s business model discards the fruit and focuses instead on the prickly pads, which are pressed to yield a juice used for a highly nutritious, low-calorie energy drink. The dried out pads are then processed to produce a light flour for the food industry or a high-protein animal feed.

“Wakonda’s circular, ecological production system also includes ‘biodigester’ tanks in which the waste from the output cycle is transformed into methane gas used as a bio-fuel either on site or sold. …

“Under Ortenzi’s business plan, rather than buying up land to plant the cactus, Wakonda aims to persuade farmers of its potential and then license out to them, in return for royalties, all the equipment and know-how required to exploit it.

” ‘The land remains yours, you convert it to prickly pears and I guarantee to buy all your output for at least 15 years,’ Ortenzi said.”

Hmmm. I have two issues. Throwing out the fruit seems super wasteful. And methane may be a biofuel, but it’s no better for the environment than fossil fuel. What do you think?

New Life for Aussie Town Halls

February 5, 2025 by suzannesmom

Photo: Landmark Media/Alamy.
Gia Carides and Paul Mercurio in Strictly Ballroom in a scene filmed in Australia’s Petersham town hall back in the day. 

This is not a new thought, but we all know of underutilized spaces and worthwhile organizations looking for space. How can we make sure we use extra space productively?

Here’s what Maddie Thomas at the Guardian says some Australian town halls are doing.

“It’s been more than three decades since Baz Luhrmann’s Strictly Ballroom was filmed in Petersham town hall. But earlier this year, the 82-year-old building in Sydney opened its doors to the Inner West Theatre Company’s production of the classic, free of charge.

“Beautiful brick early 20th-century town halls were once venues for council meetings, award nights and country dances. But in recent decades many have been under-used or left entirely empty as modern buildings serve changing community needs.

“Sydney’s Inner West council is the product of repeated amalgamations and, as a result, has an unusually large number of former town halls serving no obvious municipal purpose. Since July it has opened no fewer than seven as arts and culture venues with no hiring fees, hoping both to revive its old buildings and address a crisis in the performing arts sector.

“Since the Covid pandemic about 1,300 live performance venues around Australia have closed, leaving many in the music and arts industries struggling to stay afloat. In Sydney, revered institutions including jazz club 505 have been lost, and the number of people attending popular venues has almost halved.

“The cost of hiring a commercial venue for rehearsals and a final show can be as high as $80,000. In the first three months of the council offering its spaces free of charge, it has had more than 1,100 bookings across Marrickville, Petersham, Leichhardt, Annandale, St Peters, Balmain and Ashfield town halls, 72% of them for independent theatre, music or dance productions.

“Kane Wheatley is the musical director of the Inner West Theatre Company.

“ ‘Being able to have the town hall at no cost means that our money can be spent in putting on great productions and … providing affordable theatre in a cost-of-living crisis for members of the community,’ Wheatley says.

“His company has booked two musicals to run at the Petersham town hall in 2025. Tickets will cost $49, which just covers the costs of bringing in sound and lighting equipment. …

“The council’s mayor, Darcy Byrne, says offering affordable spaces for rehearsal, exhibition and live performance mirrors one of the original functions of town halls.

“ ‘Most town halls in Australia traditionally were used for dances, concerts, major events and so, in a way, by repurposing them as arts and cultural venues, we’re going back to their traditions,’ Byrne says. …

“After the second world war, [Lisa Murray, formerly the historian for City of Sydney council] says, councils began building civic centers to expand their services and in the 1950s there was an ‘explosion’ of municipal libraries. …

“Like many of their counterparts around the country, the Inner West buildings have retained Victorian or early 20th-century heritage features. … They offer large performance spaces with elaborate stages and commercial kitchens, and have been fitted out with live performance and recording equipment. …

“ ‘In a lot of them, the acoustics are challenging because they were designed in the era when people were giving speeches without microphones,’ Byrne says. ‘There’s acoustic treatments that may be necessary but absolutely, in every town across Australia, there is one of these beautiful buildings that’s currently being greatly under-utilized.’ …

“North of Melbourne (which is home to 30-odd town halls), Clunes is the third largest locality in Hepburn shire council. It has recently restored its town hall, built in 1873, after cracks began to appear in the masonry and the symmetrical facade started to rotate.

“The project manager at the council, Sam Hattam, says revitalization of the building gets the community engaged to start using the space.

“Thirty minutes away, the council’s headquarters at Daylesford town hall are also due to undergo restoration and electrical works later this year. Creswick town hall, renovated in 2021, is used for the newly established folk n’ roots music festival CresFest.

“ ‘The councils across Australia are spending millions and millions of dollars every year on the maintenance and repair of town halls because they have enormous heritage and civic value,’ Byrne says. ‘But the truth is most of them are sitting empty, dormant and unused for 80% or 90% of the time, which is just a waste of a great public resource.’

“Byrne hopes the momentum from such efforts will make other council areas think about throwing open their doors as Inner West has done.”

Is your town hall living its best life? What about other buildings — schools, parish halls, etc.?

Medieval Treasure Trove in Romania

February 4, 2025 by suzannesmom

Photo: Adinel C. Dincă / Biblioteca Batthyaneum.
Buried for centuries in a Transylvanian church tower, a forgotten medieval library has come to light, offering a glimpse into the intellectual and cultural life of medieval Romania.

By Jove! How many treasure troves are yet to be discovered on Planet Earth? It makes me want to start a limerick using “Jove,” “trove,” “grove” …

The website Medievalists reports, “Hidden away for centuries in a Transylvanian church tower, a forgotten medieval library has come to light, revealing treasures as old as the 9th century. This extraordinary discovery of manuscripts, books, and documents offers a rare glimpse into the intellectual and cultural life of medieval Romania.

“The discovery was made two years ago in the Church of St. Margaret in Mediaș, a 15th-century Gothic structure built by the Transylvanian Saxons. A team led by Professor Adinel C. Dincă of Babeș-Bolyai University uncovered the collection in the church’s Ropemakers’ Tower, where it had remained hidden for decades, possibly centuries. Biblioteca Batthyaneum, which first announced the find, described it as a scene straight out of an Indiana Jones adventure, complete with a struggle against nesting pigeons to recover the precious volumes. The cache includes:

  • Printed Volumes: Approximately 139 books printed between 1470 and 1600.
  • Manuscript Volumes: Two manuscripts from the early 16th century.
  • Original Documents: Around 60 documents from the 14th to 16th centuries, with a few originals and copies from the 17th century.
  • Administrative Registers: About 10 registers from the 17th–18th centuries, containing fragments of medieval manuscripts. …

“Professor Dincă believes the library was deliberately hidden, possibly during a period of war or religious upheaval. The organization of the books suggests a carefully curated collection rather than a haphazard storage. ‘When I first encountered the books, I immediately noticed the disposition of the volumes according to a certain historical typology: bibles and biblical texts, patristic, theology etc,’ Dincă explained to Medievalists.net. ‘This order doesn’t look like an improvisation. …

“The items found are likely part of a larger collection held by the church. A catalogue from 1864 lists around 7,700 books in the church library, many of which were authored by key Protestant Reformers such as Martin Luther, John Calvin, and Philip Melanchthon. The cache provides researchers with the rare opportunity to match the recovered volumes with the historical records and explore what remains of this once vast repository.

“Among the most intriguing finds are fragments of medieval manuscripts, some dating as far back as the 9th century. These include texts written in Carolingian minuscule, a script commonly associated with the Carolingian Renaissance, as well as liturgical manuscripts from the 14th and 15th centuries. Many of these fragments were found recycled into administrative registers, offering insights into how older texts were reused within the community.

“ ‘One highlight of this historical collection is the large number of original 16th-century bindings, many of them dated,’ Dincă notes. ‘In addition to that, in the series of administrative registers of the parish, there are several fragments of mediaeval manuscripts, among them one copied in Carolingian minuscule, the rest of the “fragments collection” containing the usual liturgical manuscripts from the 14th to 15th century. The closed context of re-use makes it very likely that such recycled pieces of parchment are in fact remnants of a pre-Reformation stock of manuscripts locally used.’

“The discovery has launched a comprehensive research project. … Funded by Germany’s Ministry for Culture and Media, the project focuses on preserving the collection, digitally reconstructing it, and conducting detailed scientific analysis. …

“Researchers are particularly interested in the collection’s role in reflecting the intellectual and cultural life of the Transylvanian Saxons. The books and manuscripts provide unique insights into the circulation of ideas in medieval Europe. …

“Professor Dincă and his team believe the discovery represents more than just a hidden archive — it is a time capsule that offers a rare glimpse into the cultural and religious life of the region during the Middle Ages.”

Premiering New Operas into Her 80s

February 3, 2025 by suzannesmom

Photo: Ahmed Gaber for the New York Times.
“I figured I was probably winding down,” the soprano Lucy Shelton said of her career. “But then I got wound up again.” Shelton’s latest opera is Lucidity, about identity and dementia.

Today’s story is about an 80-year-old opera singer whose career took a new lease on life. I’m always impressed by things like that, especially as I know that memory starts playing tricks. In fact, today I nearly posted a story that I posted a couple weeks ago. Of course, I’ve been blogging every day for about 13 years, getting older all the time. Bound to repeat a post by accident.

Back to the opera singer. Corinna da Fonseca-Wollheim reports at the New York Times, “When the soprano Lucy Shelton opened a recital at Merkin Hall in 2019 with ‘Adieu à la vie,’ a song by Rossini, she was about to turn 75. And though she was not bidding farewell to life as the song’s title suggests, she felt she was done with performing. For decades, she had been one of the most sought-after interpreters of contemporary vocal music. But she had reached a point where ‘I couldn’t sing the things that I used to sing,’ she said in an interview. …

‘It’s kind of a riot,’ she said. ‘It probably thrills everybody else more than it thrills me.’

“Today [last November], Shelton, 80, takes center stage at the Abrons Arts Center in the world premiere of Lucidity, an opera about identity and dementia, composed by Laura Kaminsky, with a libretto by David Cote. With a score that calls for a multitude of expressive registers, including floated lyricism and sprechstimme, musically notated recitation, the work is tailored to Shelton’s undiminished dramatic strengths. It’s also a testament to her continuing dedication to her craft. …

“After five decades making her name primarily on the concert scene, Shelton finds her engagement calendar increasingly filled with opera. In 2021, she performed in the critically acclaimed premiere of Kaija Saariaho’s Innocence in Aix-en-Provence, France. Next season, she will reprise the role at the Metropolitan Opera, making her house debut at 82. ‘It’s kind of a riot,’ she said. ‘It probably thrills everybody else more than it thrills me.’ …

“One challenge of staged roles is memorization, which can be made harder by age. In discussing Lucidity with Kaminsky, she raised her concerns that she might not be able to perform the whole show from memory. In this production, she will always have either a newspaper or sheet music to hold (her character is an aging musician), so that she has all her lines at hand. …

“Opera, though, was never the focus of Shelton’s ambitions. Growing up in Claremont, Calif., she developed a love for playfully experimental singing at home with her siblings and parents, who had met in an amateur choir. ‘We would do crazy things with our rounds or Christmas carols or Bach chorales,’ she said. ‘We might slide from tone to tone and wait until everybody got to the chord and then hold it and slurp around.’ Along the way, she said she developed a taste for ‘the thrill of dissonances.’

“She was drawn into contemporary music when she studied with Jan DeGaetani, a champion of the avant-garde known for her virtuosic facility with unorthodox techniques. Among those was DeGaetani’s dramatic use of sprechstimme in Schoenberg’s Expressionist chamber drama Pierrot Lunaire, which would also become a signature role for Shelton.

“Working primarily in contemporary music, Shelton developed an instrument that prized rhetorical impact and sound color over the high gloss favored by opera. She often performed with a microphone (including in Saariaho’s Innocence), saving her voice from the strain of projecting full-throttle to the last row of a large auditorium.

“She worries that concentrating too much on opera can stymie young singers’ curiosity about the full spectrum of expressive colors in their voices. She said she often reinvented her technique to match the dramatic demands of a given piece. By contrast, an aspiring opera singer hustling for work is forced into a loop of preparing for and performing at auditions. ‘That’s not making music,’ Shelton said. ‘It’s making an impression.’ …

“Still, Shelton knew she needed help with her singing when her 75th birthday came and went and the invitations to perform kept coming. She had lost some of her upper extension, and struggled to keep her tone even across her range. Her intuitive approach to technique no longer served her.

“For the past two years, she has been taking lessons from Michael Kelly, a baritone she met at the Tanglewood Institute when she was his mentor. He remembers being in awe of her. ‘She was probably the vocalist who had collaborated with the most composers ever,’ he said in a video interview. …

“Kelly said that aside from helping Shelton unlearn some habits that had crept into her technique in reaction to physical changes, there was a psychological dimension that had to be addressed. ‘Not being able to do what she could do at one point in her career made her hesitant,’ he said. ‘A lot of it was getting her out of her head about it and saying: “You don’t have to sing this the way you would have when you were 25 years old. This is the voice you have which is still very beautiful and capable.” ‘ “

Fishing Lines Kill Whales

February 2, 2025 by suzannesmom

Photo: Associated Press.
This image from the National Oceanic and Atmospheric Administration [NOAA], shows a North Atlantic right whale in the waters off New England, May 25, 2024.

Recently a long Inside Climate News essay about NOAA’s efforts to get lobster fishermen to switch to ropeless gear — and save a few whales — appeared in the Boston Globe. The approach is sound but costly for lobster fishermen struggling to make a living.

Kiley Price wrote, “It was a blessedly calm day as Scott Landry’s team set out in their inflatable boat to scan the glistening waters of Great South Channel between Rhode Island and Massachusetts for an endangered whale affectionately known as Wart. They were on a mission to save her life.

“The group, from the nonprofit Center for Coastal Studies located in nearby Provincetown, had spent the better part of three years monitoring Wart after an aerial team spotted the North Atlantic right whale with a large piece of rope lodged in her mouth.

“Instead of coming loose on its own, the fishing rope slowly tangled itself deeper into Wart’s baleens, hindering her ability to eat and reproduce. Finally, Landry’s team decided to take a more hands-on approach — a dangerous but necessary last resort. …

“His team had to rig up a tool that could slice the rope at a distance — essentially a crossbow with an arrow like a throwing star. Eventually, Wart came up for air close enough to Landry’s dinghy for him to get a single clean shot. He took a breath and fired. The whale immediately dove underwater again, leaving the team in suspense. A few minutes later, she popped back up, revealing the knife had cut right through the chunky rope. …

“Wart’s case is a rare bright spot in the pervasive problem of rope entanglements, one of the leading causes of death for whales. …

“The situation is particularly dire for North Atlantic right whales like Wart, with only around 350 left in the wild. Found along the East Coast of North America, the whales’ migratory paths overlap with highly productive lobster fishing areas in Maine and Massachusetts, where scientists say the whales struggle to dodge copious amounts of gear and traps. …

“Scientists and conservationists are scrambling to find a strategy to reduce entanglement risk without threatening the lobster industry, which is facing its own struggles with climate change. In recent years, a seemingly simple approach has taken center stage: getting rid of the rope.

“The traditional lobster traps that sit on the seafloor are connected to the surface by a line of rope attached to a floating buoy. But the National Oceanic and Atmospheric Administration (NOAA) is working with manufacturers and partners to help develop different high-tech traps that they can sink to the seafloor without the rope tethered to the surface — in hopes of giving whales an unobstructed path through fishery waters. Then lobstermen can use a device to call these wireless traps back up to the surface with their catch.

“Officials say this ‘ropeless’ on-demand gear could help people continue to work during seasonal fishing closures. Enacted by the federal government in New England over the past decade, these restrictions limit lobster harvesting at different times of the year during the whales’ migration season. As whale populations struggle to bounce back, more potential closures loom. …

“The problem? Many lobstermen don’t want it.

“Rob Martin’s lobster boat carved through the gray waters off Cape Cod’s Sandwich Marina this May, temporarily transformed into a gear testing laboratory. NOAA scientists and tech experts had squeezed in alongside Martin, a Massachusetts lobsterman, and his crewmate, former lobsterman Marc Palombo.

“Martin brought the boat to a halt once they were far enough out in the bay, and the team dropped on-demand traps into the water, which quickly sank to the seafloor. Several minutes later, Martin activated the gear using a device onboard. … A few yards away, a bright yellow buoy that had been underwater a moment before now bobbed in the water. Martin and Palombo fished the float out of the water, revealing a cage with a string of lobster traps attached to it. …

“This year, fishers from 19 vessels participated in restricted area trials using on-demand equipment borrowed from a NOAA-run ‘gear library’ located in Woods Hole, Massachusetts. Under a special permit, the participants are allowed to keep and sell their catches throughout the winter and spring months. …

“The end goal for these ropeless gear efforts is to give lobstermen an option to get back out on the water during seasonal fishing closures or restrictions. That includes one in place since 2015 across a stretch of Cape Cod Bay every February to April. The federal government is likely to establish new large closures in just a few years to prevent right whales from going extinct. …

“In 2022, the Massachusetts Division of Marine Fisheries published a report to assess the feasibility of ropeless gear throughout the state, produced by the ocean policy consulting company Homarus Strategies. To assess potential economic impacts, Homarus combined the estimated costs of switching to ropeless gear with the potential loss of revenue from the additional time it takes to operate the gear compared to traditional traps — and the findings were stark. If the government mandates a fisheries-wide shift to ropeless gear, the state could lose around $24 million in revenue per year, according to the report.

“There’s a big caveat to that conclusion: The government has no plans to require this type of shift, said Colleen Coogan, branch chief for the Marine Mammal and Sea Turtle Team at NOAA Fisheries Greater Atlantic Region’s Protected Resources Division.

“ ‘We’ll never require fishermen to use ropeless gear, but that means that if they don’t use it, there will be areas that will be closed for fishing,’ she told Inside Climate News. ‘It’s more that the closure is what helps the whales; the ropeless [gear] is what helps the fishermen.’ …

“ ‘Personally, I don’t think there’s anything that they’re going to be able to do to make it viable … to deal with the financial burden,’ said Cape Cod lobsterman Jeff Souza, whose house is the collateral for a loan he took out a few years ago to build a new boat. … ‘I just want to keep being able to fish and not go broke.’ …

“In the fight to pull right whales back from the brink of extinction, there is a bright spot. Last year, NOAA released the annual population estimate for the species using the most up-to-date data, and found that the rate of their decline is slowing down, likely due to the regulations protecting them. Research suggests that ropeless gear could further help. …

“Landry thinks whales can deal with ‘some level of challenge that we throw at them, but, you know, it’s pile upon pile. There’s the changing of the prey, there’s the rope, there’s the boats. You’re asking a lot of a population of 350 animals.’ ”

An App for Disrupted Education

February 1, 2025 by suzannesmom

Muhammad Auwal Ahmad wears a cap and shirt with the Flowdiary logo during a meetup in KanoNigeria with some of his educational app’s tutors and students.

Whenever I used to read about Boko Haram terrorists in Nigeria, all I could think was how horrifying and hopeless the situation seemed. But it’s amazing how the human spirit can work around almost any hopeless situation.

Today’s story is about the young man who invented an app to help displaced Nigerian youth learn skills — despite terrorists and a disrupted education.

Nathaniel Bivan reports at the Christian Science Monitor, “Seventeen-year-old Ahmad Aminu finished secondary school and would like to go to college near his village in Zamfara state. But this region of northwestern Nigeria bears the brunt of attacks by bandits who kidnap students for ransom. …

“The 17-year-old Mr. Aminu [has] been able to take – for free, or at very little cost – courses in various digital skills in Hausa. He is becoming a well-known graphic designer within the community surrounding Dalba.

“ ‘The payment depends,’ says Mr. Aminu, the excitement clear in his voice. Designing an invitation card, for example, earns him about 2,000 Nigerian nairas, about $1.25; doing video editing, up to 3,000 nairas.

“ ‘In a month, I make as much as 30,000 naira,’ he says. ‘I really thank God.’ …

“Mr. Aminu is the sort of student whom Muhammad Auwal Ahmad had in mind when he created Flowdiary two years ago as a 23-year-old attending Federal University Gashua in northeastern Yobe state. He says Flowdiary now has more than 8,000 students enrolled from far-flung, impoverished areas across northern Nigeria; on average, almost one-fifth of those are active weekly users. The platform’s name refers to opportunities flowing to young people who might not normally have them.

“ ‘We have students from regions affected by terrorism and banditry … that we train and mentor,’ Mr. Ahmad says, noting that students who speak only Hausa struggle to find online courses in digital skills in their language.

“Mr. Ahmad’s dream began in Bayamari, a village in Yobe state that has only two small schools, a health center, and a police outpost. As a curious tween growing up there, Mr. Ahmad started researching digital technology when his father brought home a mobile phone and, later, a computer. Gradually, Mr. Ahmad started troubleshooting and soon had ambitious digital goals. …

“After unsuccessful attempts at building a couple of online businesses as an undergraduate computer science student, Mr. Ahmad set up Flowdiary in March 2022. It started as a team of tutors, who included some of his friends, teaching digital skills on Telegram to other young people across northern Nigeria at low cost.

“By that November, students could access the Flowdiary website. In February 2023, the app’s release became official. Paying as little as 1,200 nairas per course, students could register to learn web development, graphic design, and other digital skills. Tutors net half of the proceeds from course fees, and the rest goes toward operational costs such as maintaining the app and helping link Flowdiary students with career opportunities, Mr. Ahmad explains.

“Registered as a business, not as a nonprofit, Flowdiary has struggled to find other funding. … But Mr. Ahmad says he is set to obtain some much-needed funding after winning the 2024 Yobe State Research and Innovation Challenge, a prestigious regional competition organized by the Biomedical Science Research and Training Center of Yobe State University, in partnership with Yobe’s state government. …

“In 2011, Al’amin Dalha Suleiman and his seven family members abandoned their home in Maiduguri, the capital of northeastern Borno state, because of the Boko Haram insurgency there. They fled to Kano, more than 500 kilometers (about 310 miles) away, mourning the deaths of neighbors and friends as well as the loss of the family’s hat shop. But discrimination in Kano against outsiders forced them to return three years later to Maiduguri, where Mr. Suleiman struggled to revive the family business. …

“Through a friend on Facebook, Mr. Suleiman heard last year about Flowdiary. He enrolled in several courses, including video editing, web development, and graphic design. There was a major challenge, though – the need for wireless data and a laptop. For months, Mr. Suleiman struggled to finish the courses over his phone, but the payoff – the skills he has acquired – has been worth it. …

“Mr. Ahmad currently teaches computer science in northwestern Kebbi state as part of his National Youth Service Corps requirement. His vision after the one-year program is to expand the Flowdiary platform to reach more young people and – crucially – to help them grow their skills into careers.

“The end of online training for each student does not necessarily mean goodbye at Flowdiary. The Flowdiary team recently set up a mentoring and internship program; any student who takes a course can apply to work with companies that Flowdiary has forged a relationship with. As of late September, 20 students had secured internships – including two with Abdul Gusau, the owner of Abdoul Shoe Ventures in Zamfara.

“ ‘It is impressive to see how effective Flowdiary is through the work the interns are putting in my store,’ Mr. Gusau says. “ ‘The graphic designer has not yet entered the intermediate class, and yet his work is excellent. The same goes for the social media manager, who runs effective ads.’ “

How Animals Self-Medicate

January 31, 2025 by suzannesmom

As a hunter lands several arrows in his quarry, a wounded doe nibbles dittany to heal herself.

I think we don’t give enough credit to ancient wisdom. Researchers of former times may have been ignorant of cars and computers and smart phones, but why do we think they were unintelligent? (I’m a little cranky because I recently attended a talk on reflexology that barely mentioned traditional Chinese medicine.)

Today we learn that art works from centuries ago suggest humans were observing animals self-medicating long before contemporary scientists started publishing papers on the practice.

Adrienne Mayor, a classics, history and philosophy of science scholar at Stanford University, writes in the Conversation, “When a wild orangutan in Sumatra recently suffered a facial wound, apparently after fighting with another male, he did something that caught the attention of the scientists observing him.

“The animal chewed the leaves of a liana vine – a plant not normally eaten by apes. Over several days, the orangutan carefully applied the juice to its wound, then covered it with a paste of chewed-up liana. The wound healed with only a faint scar. The tropical plant he selected has antibacterial and antioxidant properties and is known to alleviate pain, fever, bleeding and inflammation. …

“In interviews and in their research paper, the scientists stated that this is ‘the first systematically documented case of active wound treatment by a wild animal’ with a biologically active plant. …

“To me, the behavior of the orangutan sounded familiar. As a historian of ancient science who investigates what Greeks and Romans knew about plants and animals, I was reminded of similar cases reported by Aristotle, Pliny the Elder, Aelian and other naturalists from antiquity. A remarkable body of accounts from ancient to medieval times describes self-medication by many different animals. The animals used plants to treat illness, repel parasites, neutralize poisons and heal wounds.

“The term zoopharmacognosy – ‘animal medicine knowledge’ – was invented in 1987. But as the Roman natural historian Pliny pointed out 2,000 years ago, many animals have made medical discoveries useful for humans.

Indeed, a large number of medicinal plants used in modern drugs were first discovered by Indigenous peoples and past cultures who observed animals employing plants and emulated them.

“Some of the earliest written examples of animal self-medication appear in Aristotle’s ‘History of Animals‘ from the fourth century BCE, such as the well-known habit of dogs to eat grass when ill, probably for purging and deworming.

“Aristotle also noted that after hibernation, bears seek wild garlic as their first food. It is rich in vitamin C, iron and magnesium, healthful nutrients after a long winter’s nap. The Latin name reflects this folk belief: Allium ursinum translates to ‘bear lily,’ and the common name in many other languages refers to bears.

“Pliny explained how the use of dittany, also known as wild oregano, to treat arrow wounds arose from watching wounded stags grazing on the herb. Aristotle and Dioscorides credited wild goats with the discovery. Vergil, Cicero, Plutarch, Solinus, Celsus and Galen claimed that dittany has the ability to expel an arrowhead and close the wound. Among dittany’s many known phytochemical properties are antiseptic, anti-inflammatory and coagulating effects.

“According to Pliny, deer also knew an antidote for toxic plants: wild artichokes. The leaves relieve nausea and stomach cramps and protect the liver. To cure themselves of spider bites, Pliny wrote, deer ate crabs washed up on the beach, and sick goats did the same. Notably, crab shells contain chitosan, which boosts the immune system.

“When elephants accidentally swallowed chameleons hidden on green foliage, they ate olive leaves, a natural antibiotic to combat salmonella harbored by lizards. Pliny said ravens eat chameleons, but then ingest bay leaves to counter the lizards’ toxicity. Antibacterial bay leaves relieve diarrhea and gastrointestinal distress. Pliny noted that blackbirds, partridges, jays and pigeons also eat bay leaves for digestive problems.

“Weasels were said to roll in the evergreen plant rue to counter wounds and snakebites. Fresh rue is toxic. Its medical value is unclear, but the dried plant is included in many traditional folk medicines. Swallows collect another toxic plant, celandine, to make a poultice for their chicks’ eyes. Snakes emerging from hibernation rub their eyes on fennel. Fennel bulbs contain compounds that promote tissue repair and immunity.

“According to the naturalist Aelian, who lived in the third century BCE, the Egyptians traced much of their medical knowledge to the wisdom of animals. Aelian described elephants treating spear wounds with olive flowers and oil. He also mentioned storks, partridges and turtledoves crushing oregano leaves and applying the paste to wounds.”
