“Fungi whisperer” Tarun Nayar started experimenting with connecting a synthesizer to plants and fungi during the early days of the COVID-19 pandemic. 

Today we have another example of the creative work that got a lift during the pandemic. Not that we ever want a pandemic, but it doesn’t hurt to remember that good things can flourish in the shelter of nothing-much-going-on.

Radhika Iyengar writes at Atlas Obscura about some pandemic-era experiments. “On a pleasant December morning, Tarun Nayar was at a mangrove reserve in Mumbai, where he plugged his synthesizer into a thick leaf. The sound that emerged was hypnotic and otherworldly, blending a sense of the future with nostalgic echoes of 1980s synthwave. It felt like something right out of Stranger Things.

“Nayar is not your traditional musician—he’s a fungi whisperer. By connecting cables from his custom-built modular synthesizers to mushrooms, fruits, and leaves, he transforms their natural bioelectric signals into captivating sounds. …

“Over the last five years, Nayar has jammed with myriad types of fungi, including trumpet-shaped chanterelles and the glorious, red-roofed fly agaric mushrooms. He has also collaborated with a giant ficus tree, clumps of bamboo, sword ferns, a pineapple, and even the odd-looking citrus fruit called Buddha’s Hand. ‘It’s an intoxicating feeling to be able to make all these crazy sounds and program really interesting melodies, many of which will probably be impossible to play on a traditional instrument,’ he muses.

“Music has always been central to Nayar’s life. Born to a Punjabi father and a Canadian mother, he was immersed in Indian classical music from an early age, particularly through his training in tabla, a type of hand drum. But for the past four years, the former biologist, who is based in Montreal, has been experimenting with what one may describe as plant music.

“Nayar’s journey into this experimental soundscape began during the COVID-19 pandemic, when he was living on a tiny island north of Vancouver, surrounded by nature. That’s when he began ‘messing around’ with flora. He recalls plugging a software synthesizer into a salmonberry bush. ‘All of a sudden, the synthesizer started playing a piano patch,’ he says. ‘I could actually “listen” to the salmonberry bush.’ …

“In 2021, Nayar started posting videos of his ‘little experiments’ on the internet under the stage name Modern Biology. While initially his videos on TikTok received only three to four views, slowly they gained momentum and worldwide attention, leading to tens of thousands of people appreciating his work. ‘To be honest, I was quite surprised that people were interested in this relatively niche practice. It really gave me a feeling of community during the pandemic when my bubble was quite small,’ admits Nayar. Today, he has over 379,000 followers on Instagram alone.

“To be clear, fruits, fungi, and trees don’t make music. They don’t even produce sounds that lie within the audible range of human hearing. But as Nayar explains, ‘almost every behavior in plants and fungi is mediated by electrical impulses, just like in humans. Every thought, every movement, every little cellular division is associated with an electrical activity. These signals or processes are all reflected in the conductivity of the organism’s body. All I’m doing is tapping into these fluctuating electrical fields and translating the electrical signals into musical notes.’…

“His interest in sound synthesis began several years before the pandemic, sparking a deep fascination that eventually led him to build his own analog synthesizers at home. He pursued courses focused on DIY synthesizers made out of breadboards—versatile plastic boards with perforated holes, designed for assembling electronic circuits by plugging in jumper cables. …

“One of the first exercises in the online course involved the humble orange. ‘We had to use it in a circuit as a resistor,’ Nayar recalls. ‘Everything has electrical resistance, but some materials are so resistant that current can’t even pass through them. Fruits and vegetables, however, are effective conductors, allowing electrical current to flow through them.’

“When Nayar squeezed the orange, he realized that its conductivity changed, and the sound changed with it. ‘The pitch of the oscillator went up or down depending on whether you were squeezing it or not,’ he says, adding with a hint of amusement, you can actually play the synthesizer just by squeezing the orange!’

“From holding festivals in parks to conducting intimate gatherings at restaurants, Nayar has been gaining attention for his experimental music. His goal is to encourage people to reconnect with nature. ‘For the most part, as human beings we kind of forget that the world is alive,’ he says.”

Radio show Living on Earth did a segment in February on new technology to store and release solar heat. Here is host Steve Curwood on his outing to MIT to learn about the breakthrough.

“A team of researchers at MIT has come up with a chemical that would let windshield glass directly store solar energy and then release it on demand as heat to melt the ice. … The same chemical could be woven into clothing fibers to capture the sun’s energy and then give you some added warmth when you ask for it, even days later.

“I paid a visit to the lab where the MIT team has been working on this breakthrough and met up with researchers David Zhitomirsky and Eugene Cho, who work in the lab of professor Jeffrey Grossman.”

To Curwood’s question about the difference between the familiar electrical, battery-enabled solar technology and the MIT lab’s chemical version, Zhitomirsky replies,”We use these molecules that can absorb UV light and instead of generating charges, what they do is that they change shape, and by changing shape, they can store chemical energy …

“CURWOOD: OK, so sunlight hits this molecule, it changes shape and can storage its energy. And how do you get the energy out?

“ZHITOMIRSKY: So you can figure the material in several ways. One way is to add a small amount of heat, and the material will release more heat than you add in. The other methods are triggering it with light or you can apply an electrical field to the material. …

“The way we envision using it is to integrate into fibers that you then make clothing out of.” More here.
