Have you ever taken out-of-town guests to see the glass flowers at Harvard? They are among the area’s must-see attractions.

The Czech father-son team Leopold and Rudolf Blaschka created the flowers in the 19th century, when they also made glass replicas of sea creatures.

Now scientists are comparing the duo’s marine life to what exists today. Have the creatures evolved? Are some extinct?

“I’ve been a marine biologist my entire professional life,” write C. Drew Harvell in the Science section of the NY Times, “spending more than 25 years researching the health of corals and sustainability of reefs. I’m captivated by the magic of sessile [attached by the base]  invertebrates like corals, sponges and sea squirts — creatures vital to the ecosystem yet too often overlooked in favor of more visible animals like sharks and whales.

“The filmmaker David O. Brown and I want to change that. To make a documentary, Fragile Legacy, we are on a quest to lure these elusive and delicate invertebrates in front of the camera lens.

“Our inspiration springs from an unlikely source: a collection of 570 superbly wrought, anatomically perfect glass sculptures of marine creatures from the 19th century.

“These delicate folds and strands of glass make up the Blaschka collection of glass invertebrates at Cornell, of which I am the curator — enchanting and impossibly rare jellyfishes of the open ocean; more common but equally beautiful octopus, squid, anemones and nudibranchs from British tide pools and Mediterranean shores.

“They are the work of an extraordinary father-and-son team, Leopold and Rudolf Blaschka.”

Today I am thinking about the South End Knitters, the stealth street artists who wrap their knitting around parking meters and fire hydrants and telephone poles.

Writes Linda Matchan in the Boston Globe, “The South End Knitters’ weekly meetings at a Washington Street café seem innocuous, but don’t be fooled. Over knitting needles and yarn at the long table they’ve commandeered, they are contemplating something far more mischievous than a sweater. They’re graffiti knitters, and they’re plotting their next target. …

“As with graffiti, no two tags in the yarn-bomber subculture are alike. They range from sleeves on parking meters to tubes on tree limbs to sweaters on statues: A recent high-profile example is the neon pink sweater that the New York street knitter Olek crocheted in December for the 16-foot ‘Charging Bull’ statue on Wall Street.”

What put me in mind of the South End Knitters was an extraordinary post at the WordPress blog Pickled Hedgehog Dilemma, which describes a crochet effort that is drawing a lot of attention to the plight of vanishing corals.

Concerned about the effect of global warming on reefs, Margaret Wertheim and her twin sister got an idea that involved “crocheting corals. They used a crocheting technique invented by mathematicians in 1997 to model hyperbolic shapes called hyperbolic crocheting. … This ended up being a perfect technique for producing coral reproductions. …

“They crocheted a lot of corals,” continues Pickled Hedgehog, ” then they did something to change the world. They shared their corals with art museums. They got a community in Chicago to crochet with them. Then the crafting became a movement and groups all over the world started to crochet corals.”
