Researchers identify a molecule that may have been key to the surprisingly common transition from single-celled ancestors to today’s complex, multicellular organisms. 

Chilly mice develop more tumors; gut bacteria aid cancer treatment; two Y chromosome genes sufficient for assisted reproduction; HIV’s “invisibility cloak”

Grasshopper mice harbor mutations in a pain-transmitting sodium channel that allow them to prey on highly toxic bark scorpions.

At age 16, Alexandra Sourakov has her first scientific publication, on the foraging behavior of butterflies.

Ancient bacteria living in deep-sea sediments are alive—but with metabolisms so slow that it’s hard to tell.
