Researchers discover the molecule that “programs” a tendency to develop an eating disorder 

Lighting up the reward center: Light-sensitive proteins are inserted into specific brain cells. Blue: dopamine-producing cells in the reward system in the ventral tegmental area. Red: cells carrying the inserted protein in a mouse brain. Yellow: Overlap between cells that are carrying the optogenetic protein and those  that are dopamine-producing.

A decades-old debate on the way signals create perception is resolved

Left: normal nerve cells; right cells genetically engineered to neutralize MTCH2. Fluorescent proteins reveal the calcium uptake in the mitochondria of these cells. The genetically engineered cells reveal dramatically less calcium uptake – evidence of the crucial role this gene plays in mitochondria function

Understanding how a gene studied in one lab affects the basic element researched in another may reveal what goes wrong in Alzheimer's
