UT Southwestern scientists discover agent that reverses effects of intoxication
A shot of a liver-produced hormone called FGF21 sobered up mice that had passed out from alcohol, allowing them to regain consciousness and coordination much faster than those that didn’t receive this treatment, UT Southwestern researchers report in a new study. The findings, published in Cell Metabolism, could lead to effective treatments for acute alcohol intoxication, which is responsible for about 1 million emergency room visits in the U.S. each year.

A study of retired professional football players by researchers at UT Southwestern Medical Center found that their cognitive abilities did not differ significantly from a control group of similarly aged men who did not play football, nor did those abilities show significant change over one to five years. The findings were published in Brain Injury.
Is brain learning weaker than artificial Intelligence?
Can the brain, with its limited realization of precise mathematical operations, compete with advanced artificial intelligence systems implemented on fast and parallel computers? From our daily experience we know that for many tasks the answer is yes! Why is this and, given this affirmative answer, can one build a new type of efficient artificial intelligence inspired by the brain? In an article published today in Scientific Reports, researchers from Bar-Ilan University in Israel solve this puzzle.

This engineering feat, led by Johns Hopkins University researchers and detailed today in Science Advances, expands what researchers can accomplish with organoids, including mini brains—the lab-grown balls of human cells that mimic some of a brain’s structure and functionality.
How not to use brain scans in neuroscience
The idea that a lone snapshot of a brain can tell you about an individual’s personality or mental health has been the basis of decades of neuroscience studies. That approach was punctured by a paper in Nature earlier this year showing that scientists have massively underestimated how large such studies must be to produce reliable findings. At the center of the research is MRI (magnetic resonance imaging) brain scans. Reaching that conclusion required getting a far broader view of the field than was possible until recently. Along with colleagues at a number of institutions as well as his advisor, Pitt Professor of Psychiatry Beatriz Luna, Tervo-Clemmens combined three recent publicly available studies that together included MRI data from around 50,000 participants.
