Obesity and metabolic disorders are increasingly significant global public health issues. In a novel study, a team of dermatologists evaluated the effect of ultraviolet (UV) exposure on appetite and weight regulation. They found that UV exposure raises norepinephrine levels, decreases leptin levels, and induces the browning of subcutaneous fat, thereby increasing energy expenditure. These results potentially pave the way for new approaches to prevent and treat obesity and metabolic disorders.

The brain is often referred to as a 'black box'-- one that's difficult to peer inside and determine what's happening at any given moment. This is part of the reason why it's difficult to understand the complex interplay of molecules, cells and genes that underlie neurological disorders. But a new CRISPR screen method has the potential to uncover new therapeutic targets and treatments for these conditions.
