On TreeHugger, the degradation of lithium-ion batteries, a giant igloo made with old fridges (?!), a surprising robotic hand, turning old NiMH batteries into new ones, and a GPS transmitter inside a rhino's horn.
Researchers at the Ohio State University have been slicing and dicing old lithium-ion batteries to find out why they degrade on the molecular level. Their discoveries can help eventually make better batteries.
This amazing piece of conceptual art sends a message about how wasteful old fridges are. Very cool.
It is tough picking things up; one has to coordinate fingers and get feedback. It is harder still to make a robotic hand that can master the complexities. We have a tendency build these things in our own image, but it turns out that sometimes simpler is better.
Toyota is opening the first recycling plant that can directly turn old hybrid batteries into new hybrid batteries.
In addition to their thick, leathery hide and imposing stature, now a group of African rhinos have one more tool to help protect them against poachers — GPS locating devices embedded directly into their horns.
