Science News! Let’s take a look at some of the important developments in science this week…
First, researchers at Princeton University have produced 3D footage of the brain activity of a nematode. This is the first time that such a detailed view of brain wide neural activity with single neuron resolution in a free moving animal has been captured, and could help in understanding how neurons coordinate motion and behavior.

Second, scientists have found that they can change the social behavior of ants using epigenetic drugs. By changing gene expression, but not the DNA sequence itself, the researchers were able to alter the behavior of individual ants that would usually act in accordance to the ant caste to which they belonged.

Third, researchers have successfully used gene editing to treat mice with Duchenne muscular dystrophy. A system was used that deleted DNA preventing cells from producing a protein that is essential for muscle function, and a virus was used to deliver the alteration into the cells of the mice.
