The Nobel Prize for Physiology (or Medicine) was announced on Oct. 2 in Sweden. Three American scientists jointly took home this prestigious award for their work on circadian rhythms. This is the biological clock all organisms have which controls our sleep-wake cycle, the release of hormones at important intervals, body temperature, blood pressure, and other critical mechanisms, in order to maintain homeostasis or balance.

Scientists Use CRISPR Gene Editing to Create the World's First Mutant Social Insect

Researchers succeed in deleting key genes from ants, significantly modifying their behavior.

A staple of bad science fiction, mutant ants have been more of a figment of imagination rather than scientific reality. We’ve genetically altered mice and fruit flies, but growing mutant ants has eluded scientists due to the complex life cycle of the little critters. Now two teams announced that they managed to edit out certain genes from lab ants, altering their behavior.
