How cell nuclei squeeze into tight spaces
As cells move throughout our bodies, they often have to squeeze through tight nooks and crannies in their environment, reliably springing back to their original shape. The structures involved in this process are still a mystery, but in a study published Aug. 22 in Developmental Cell, a research team reports one protein responsible for giving a cell's nucleus its durable, deformable nature. These results, the authors say, may explain the invasiveness of certain cancer cells. (2016-08-22)

Long-term health effects of Hiroshima and Nagasaki atomic bombs not as dire as perceived
The detonation of atomic bombs over Hiroshima and Nagasaki in August 1945 resulted in horrific casualties. The long-term effects of radiation exposure also increased cancer rates in the survivors.
