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.
New research from the UC Davis School of Medicine and collaborating institutions solves the mystery of how mutations in the same gene can cause serious heart disease or severe skin disease — but never both. The findings were published in the Proceedings of the National Academy of Sciences (PNAS).
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.
UC San Diego biologists have identified a way to reinvigorate immune system cells, which can become exhausted after fighting disease. They found that protein recycling malfunctions after a cell burns out. Restoring a proper recycling system allows T cells to regain their cancer-fighting functions.
