Medical Xpress / Testosterone increases severity of bacterial skin infections, researchers discover

Men are more susceptible than women to skin infections caused by Staphylococcus aureus bacteria, but the biological basis for this disparity has remained unclear. A new study led by UT Southwestern Medical Center researchers ...

Phys.org / Dogs are more like toddlers than cats when it comes to helping humans

Why does your dog rush to "help" when you are searching for something, while your cat seems… eh, less concerned? New research suggests that this difference may stem from deep evolutionary roots—and that, in certain situations, ...
