Common weight-loss drug successfully targets fat that can endanger heart health

Researchers at UT Southwestern announced successful results of a clinical trial for a commonly prescribed weight-loss drug called liraglutide. In adults who are overweight or have obesity combined with high cardiovascular risk, once-daily liraglutide combined with lifestyle interventions significantly lowered two types of fat that have been associated with risk to heart health: visceral fat and ectopic fat.

A peek inside a flying bat’s brain uncovers clues to mammalian navigation

When driving up to a busy intersection, you probably pay more attention to where you will be in the near future than where you are at that moment. After all, knowing when you will arrive at the intersection — and whether you need to stop or slow down to avoid a collision with a passing car, pedestrian or cyclist — is usually much more important than knowing your current location.

SARS-CoV-2 Detectable — Though Likely Not Transmissible — on Hospital Surfaces

Watching what was happening around the world in early 2020, University of California San Diego School of Medicine researchers knew their region would likely soon be hit with a wave of patients with COVID-19, the infection caused by the coronavirus SARS-CoV-2. They wondered how the virus persists on surfaces, particularly in hospitals, and they knew they had only a small window of time to get started if they wanted to capture a snapshot of the “before” situation — before patients with the infection were admitted.

Same Difference: Two halves of the hippocampus have different gene activity

A study of gene activity in the brain’s hippocampus, led by UT Southwestern researchers, has identified marked differences between the region’s anterior and posterior portions. The findings, published today in Neuron, could shed light on a variety of brain disorders that involve the hippocampus and may eventually help lead to new, targeted treatments.

Giving brown fat a boost to fight Type 2 diabetes

Increasing a protein concentrated in brown fat appears to lower blood sugar, promote insulin sensitivity, and protect against fatty liver disease by remodeling white fat to a healthier state, a new study led by UT Southwestern scientists suggests. The finding, published online in Nature Communications, could eventually lead to new solutions for patients with diabetes and related conditions.
