An imagined conversation between two yeast cells appears in Kurt Vonnegut’s 1973 novel Breakfast of Champions. “They were discussing the possible purposes of life,” Vonnegut writes. If that’s not absurd enough, their existential discussion takes place against a weird, dismal backdrop, “as they ate sugar and suffocated in their own excrement.” Little did they know, their little yeasty lives had an important, human-centric purpose. “Because of their limited intelligence, they never came close to guessing that they were making champagne.” Continue reading

We’ve been highlighting mycological innovation since the early days of this site, and our enthusiasm has yet to wane. The range of fungi-power will never cease to amaze.
A Danish biotechnology company is trying to fight climate change — one laundry load at a time. Its secret weapon: mushrooms like those in a dormant forest outside Copenhagen.
In the quest for a more environmentally friendly detergent, two scientists at the company, Novozymes, regularly trudge through the mud, hunting for oyster mushrooms that protrude from a fallen beech or bracken fungi that feast on tough plant fibers. They are studying the enzymes in mushrooms that speed up chemical reactions or natural processes like decay.
“There is a lot going on here, if you know what to look for,” said Mikako Sasa, one of the Novozymes scientists.
Their work is helping the company develop enzymes for laundry and dishwasher detergents that would require less water, or that would work just as effectively at lower temperatures. The energy savings could be significant. Washing machines, for instance, account for over 6 percent of household electricity use in the European Union.
Enlisting enzymes to battle dirt is not a new strategy. Over thousands of years, mushrooms and their fungi cousins have evolved into masters at nourishing themselves on dying trees, fallen branches and other materials. They break down these difficult materials by secreting enzymes into their hosts. Even before anyone knew what enzymes were, they were used in brewing and cheese making, among other activities.

The Science section of the New York Times is a dependable source of occasionally brilliant ecological findings (amidst the more common overdoses of dark and dreary news) and this one helps start a new week on solid ground:
A new genetic analysis reveals the tactics that helped fungi in the Armillaria genus get so good at expanding and killing host plants.
Thousands of years ago, two microscopic spores spawned and created a monster. It grew — up to three feet a year — sending out dark, gnarly, threadlike organs called rhizomorphs that explored the subterranean darkness, foraging for food. Now it’s a nebulous body, a tangled mat beneath the Oregon soil that occupies an area the size of three Central Parks and may weigh as much as 5,000 African elephants.
Its scientific name is Armillaria ostoyae, but you can call it The Humongous Fungus. It’s the largest known terrestrial organism on the planet, according to the United States Forest Service.

Thanks again to Stephanie Strom for a story about ecology that surprises:
For the environmentally conscious eater, they are among the most inconvenient truths: Too much food goes to waste. Too much packaging comes with the food. And too much of the packaging is made to last for ages.
Now there may be a single answer to all three problems: using excess food to make the packaging. Continue reading
Forests and fungi–words that make me think of Milo circa 2010-2012 in the south of India, especially in the Periyar Tiger Reserve (but also later, writing about fungi in relation to food waste). When I first heard this a week ago, it seemed typical of Radiolab’s attention to quirky outlier science stories:

A forest can feel like a place of great stillness and quiet. But if you dig a little deeper, there’s a hidden world beneath your feet as busy and complicated as a city at rush hour.
In this story, a dog introduces us to a strange creature that burrows beneath forests, building an underground network where deals are made and lives are saved (and lost) in a complex web of friendships, rivalries, and business relations. It’s a network that scientists are only just beginning to untangle and map, and it’s not only turning our understanding of forests upside down, it’s leading some researchers to rethink what it means to be intelligent.
And it was typical, in that sense. But Milo’s attention to the underworld of fungi, which at the time seemed to me as quirky as this Radiolab story does today, got me to start paying attention to anything in our news network with certain keywords (mushroom, fungi, etc.) and just now I came across a short journalistic account that taps into the same science as the Radiolab piece above, and I am realizing it may not be merely quirky: Continue reading
