What is Next Nature?

With our attempts to cultivate nature, humankind causes the rising of a next nature, which is wild and unpredictable as ever. Wild systems, genetic surprises, autonomous machinery and splendidly beautiful black flowers. Nature changes along with us.

The Future of Solar Power? Snail Teeth!

Gumboot chiton is a marine snail with an appetite for algae growing on rocks. Grazing on rocks would destroy the teeth of others, but not the gumboot chiton. This snail produces the hardest biomineral yet discovered to deal with its punishing eating habits.

This mineral, called magnetite, has inspired a new type of solar cell and a new type of lithium battery. By understanding how the snail produces this mineral, researchers could develop similar ways to make nano-materials at room temperature. This will allow researchers to develop low-cost, high-efficiency microscopic structures.

Dr. Kisailus, of Riverside’s Bourne College of Engineering in California, believes that understanding the gumboot chiton will lead to solar cells that can capture and convert more sunlight into electricity, as well to more efficient batteries. “If we can reduce the size of particles in batteries, which at present, are massive on a nano-scale, this will reduce their recharge time and increase their power efficiency”.
