Phys.org / Look to women for sustainable livestock farming bordering the Amazon rainforest, says study
When trees and livestock compete for land, the trees usually lose. It doesn't have to be this way. But centrally designed plans to implement tree-livestock coexistence in deforested areas don't always work on faraway farmland.

Phys.org / 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 ...
