Turning a quantum battery's environmental sensitivity into an advantage
Quantum batteries, devices that store energy by exploiting quantum mechanical phenomena, could, in principle, be charged faster and more efficiently than classical ones. Despite their potential, connecting these batteries ...
Shrews exhibit reversible size changes in their skulls and noses to get through the winter
Scientists had previously observed that some species of shrews undergo a form of biological plasticity in which their bodies, skulls, brains and some organs shrink in the winter, then regrow in the spring. Now, a new study ...
Astronomers catch hot birth of galaxy cluster more than 11 billion light-years away
