Mega study charts how genetic variants affect metabolism
A genome-wide association study of metabolic biomarkers in 136,000 participants discovered more than 400 independent genomic regions affecting metabolism. The study also highlighted the importance of participant characteristics, such as fasting status, that can substantially affect the genetic associations.

Oxytocin produced by neurons in fat tissue releases stored lipids
The hormone oxytocin is secreted by the brain during labour and lactation. It has also been associated with lipid release from intracellular stores, but the physiological implications of this were unknown. This study shows that oxytocin is produced locally by neurons that innervate the adipose tissue and is required for maximizing energy release from fat.
