Newly discovered crater suggests multiple asteroids killed dinosaurs

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.

Floating artificial leaves produce fuels from water, air and sunlight

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.

Graphene-infused mesh could keep rotator cuff injuries from recurring

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.

Hydrogel bandage uses ultrasound to better stick to the skin

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.

New polymer removes dye from wastewater, and can be reused afterwards

In wastewater produced by the textile industry and others, dye is one of the primary pollutants. A newly developed synthetic polymer is capable of removing that dye from the water, plus it can be cleaned up and reused to treat more wastewater.
