New simulations reveal hot neutrinos trapped during neutron star collisions

When stars collapse, they can leave behind incredibly dense but relatively small and cold remnants called neutron stars. If two stars collapse in close proximity, the leftover binary neutron stars spiral in and eventually ...

Backdoor method creates high-entropy material at lower temperatures

Entropy is a hot mess. Randomness and disorder are not exactly virtues in science. Yet it turns out, a sloppy jumble of differently sized atoms can do a better job stabilizing certain nanocrystals than a tidy arrangement ...

Unexpected diversity of light-sensing proteins goes beyond vision in frogs

Frogs have maintained a surprising diversity of light-sensing proteins over evolutionary time, according to a new study led by a Penn State researcher. Light-sensing proteins, called opsins, enable vision in sighted animals, ...

Tanzania fertilizer use increased after intervention, but changes were not sustained, study shows

Smallholder farmers in Sub-Saharan Africa tend to use very small amounts of fertilizer, limiting their crop productivity. A 2016 intervention in Tanzania increased farmers' fertilizer use and their crop yields. However, a ...
