Miscalibrated Internet Receptor Stalks

Sloths and opera singers grow their own food. They also wear it.

Growing edible algae on one's own body was a hip biotech art project. But sloths had invented wearing their own algae farm long time ago. Sloths move so slowly that algae and fungi grow in their hair. It's the best camo wear ever, asserts a study from the University of Helsinki.


The finish researchers also found that sloth babies feed on the algae growing on the sloth hair. That reminds me of Algaculture, designed by British artists Michael Burton & Michiko Nitta.

Could humans use algae to gain food from light and carbon dioxide? Burton and Nitta provide the recipe: mix biotech and art, with a dash of slow food movement and pinch of space travel fantasy. They had a live demo, the Algae Opera. After the concert, listeners tasted the freshest green smoothie ever, made from algae grown in a device worn by mezzo-soprano Louise Ashcroft.


My inner skeptic questions how sloths handle disease-causing organisms in their fur. And how humans handle the taste of plastic or the cleaning up all those tubes. But sloths are in lately. And art is always in.
