Ultra-Thin Solar Cells Turn Any Surface Into a Power Source

Researchers at MIT have developed lightweight yet durable solar cells that can be applied to any surface to create a power source. Thinner than a strand of human hair and one-hundredth the weight of solar panels, these cells vastly improve the versatility and adaptability of solar energy, fitting onto the sails of boats, wings of drones or tents and tarps during emergency situations. They also …

Physicist Jess Wade Pens 1,750 Wikipedia Pages for Women Scientists

Upon discovering that renowned American climatologist Kim Cobb did not have a Wikipedia page, Jess Wade (British physicist and research fellow at Imperial College London) penned her entry—before continuing on a quest to document other women and minority scientists, as well as engineers. Wade has now written more than 1,750 Wikipedia pages for notable figures. “Wikipedia is a really powerful way to give credit to …

Making a Lithium-Ion Battery Alternative Out of Crab Exoskeletons

Products powered by lithium-ion batteries (like electric vehicles) are in high-demand, but sourcing and mining the element requires unsustainable amounts of water and energy. On top of that, it’s a scarce resource and acquiring it can be dangerous. To find an alternative, engineers from the University of Maryland created a battery using crabs whose exoskeletons are rich in useful chemicals like chitin, a natural polymer …
