No, the human brain did not shrink
Researchers refute a hypothesis that the human brain shrank 3,000 years ago as a result of the transition to living in modern societies. Last year, a study was widely circulated in which…
What influences where scarab beetles roll their dung balls?
A numerical model helps scientists understand how particularities of different terrains affect the trajectory and behavior of dung beetles. Out in a sunny field scampers a black scarab beetle, making its way…
In situ cancer vaccine captures antigens from tumors
A new in situ, personalized cancer vaccine captures molecules from growing tumors to activate the body’s immune cells against them. Cancer is a complex disease, and as a result of a myriad…
