Germ-free lungs of newborn mice are partially protected against hyperoxia

Germ-free lungs of newborn mice are partially protected against hyperoxia

Researchers have used a novel and first-of-its-kind newborn mouse model to study the effect of high oxygen concentrations, or hyperoxia, on lung development of newborn mice that are germ-free -- meaning no microbes colonizing their lungs. Their goal is to learn how differences in the types of microbes that already colonize human lungs at birth -- including extremely premature infants...

Breaking (and restoring) graphene's symmetry in a twistable electronics device

Breaking (and restoring) graphene's symmetry in a twistable electronics device

A recent study demonstrates a new way to tune the properties of 2D materials simply by adjusting the twist angle between them. The researchers built devices consisting of monolayer graphene encapsulated between two crystals of boron nitride and, by adjusting the relative twist angle between the layers, they were able to create multiple moiré pattern--''the first time anyone has seen...
