Aluminum has an energy density more than 50 times higher than lithium ion, if you treat it as an energy storage medium in a clean redox cycle system. Swiss scientists are developing the technology as a renewable energy stash for the European winter. Source of Article
Polystyrene is a problematic material when it comes to recycling, but a team of Virginia Tech researchers is hoping to change this with a novel method that turns it into a product of relatively high value. Source of Article
Scientists have discovered a new crater in the seabed of the North Atlantic Ocean that seems to date to the end of the Cretaceous period. That suggests the extinction event that killed off the dinosaurs could have been triggered by multiple impacts. Source of Article
Leaves are impressive machines, converting sunlight, carbon dioxide and water into energy. Cambridge scientists have now created artificial leaves that can float on water, tapping into sunlight above it and water below to efficiently produce fuels. Source of Article
A new study on fruit flies may help explain why siestas came to be such an important habit in many cultures, revealing a type of brain thermometer that kicks sleep-promoting cells into action as the mercury starts to climb. Source of Article
A torn rotator cuff can be debilitating enough on its own, but unfortunately once such an injury has occurred, it's more likely to happen again. An experimental new mesh could help keep that from happening, thanks to tiny pieces of graphene. Source of Article
Armored dinosaurs like Stegosaurus and Ankylosaurus were mostly big, bulky animals that walked on four legs, but paleontologists have now discovered a bizarre relative the size of a dog that strutted around on two legs. Source of Article
Joint pain is a common ailment of aging, thanks to cartilage’s tendency to wear out. Researchers at Duke University have developed a new hydrogel that’s stronger and more durable than the real thing, which could make for longer lasting knee implants. Source of Article
A cornea implant made out of collagen gathered from pig skin has restored the vision of volunteers in a landmark study. Pending further testing, the novel implant is hoped to improve the vision of millions waiting for difficult transplant surgeries. Source of Article
Getting a bandage to stick to your skin can sometimes be difficult, particularly if that skin is wet. This isn't a problem with an experimental new wound dressing however, which uses ultrasound-induced microbubbles to better bond with the skin. Source of Article
