People with obesity face a significantly increased risk of atherosclerosis, and consequently heart attack and stroke. This elevated risk is largely driven by chronic inflammation in the blood vessels, which is more common in severe obesity. A new study led by Florian Kiefer at the Division of Endocrinology and Metabolism, MedUni Vienna, has now identified brown adipose tissue (brown fat) as a potential protective factor for vascular health. The findings, published in Atherosclerosis, Thrombosis and Vascular Biology, show for the first time in humans that individuals with obesity and active brown fat exhibit significantly lower arterial inflammation.
Blood tests measuring the aging of certain white blood cells can predict cognitive and mood-related symptoms of depression, rather than physical symptoms.
The findings, published in The Journals of Gerontology, Series A: Biological Sciences and Medical Sciences, bring researchers closer to identifying a biomarker for detecting the mood disorder, which affects nearly one in five US adults.
For decades, scientists have wondered what triggered the sudden "explosion" of complex animal life on Earth. This new hypothesis suggests that the answer isn't found in shells or legs, but in the evolution of the brain as a response to an increasingly crowded and tiered ocean. By developing the genetic "blueprints" to organize a complex nervous system first, a few lucky lineages were able to recycle those same instructions to build the most diverse and sophisticated bodies in nature.
Two University of Virginia scientists have been elected to the prestigious American Academy of Arts & Sciences, a storied group founded during the Revolutionary War by John Adams, John Hancock and 60 other scholar-patriots to advance the public good.
Penn Engineers have developed a new way to use AI to solve inverse partial differential equations (PDEs), a particularly challenging class of mathematical problems with broad implications for understanding the natural world. The advance, which the researchers call “Mollifier Layers,” could benefit fields as varied as genetics and weather forecasting, because inverse PDEs help scientists work backward from observable patterns to infer the hidden dynamics that produced them.
During early stages of an epidemic, a host’s genetics and sex influence how a virus evolves, according to new research. Using lab mice, University of Utah biologists found the influenza virus can gain virulence more quickly as it passes through females that generate a stronger immune response.
