Major depressive disorder (MDD) is a debilitating condition that affects more than 246 million people worldwide, yet scientists have struggled to identify consistent brain markers that could improve diagnosis and treatment. Finding reliable neurobiological markers for MDD has been hampered by the methodological differences observed across neuroimaging studies. Traditional brain imaging studies have produced conflicting results, often due to differences in methods and analysis pipelines. This inconsistency has made it difficult to pinpoint reliable neurobiological signatures of depression.

Olympic skiers, bobsledders and speed skaters all have to master one critical moment: when to start. As athletes prepare for the upcoming Winter Olympics, that split second is in the spotlight because when everyone is fast, strong and skilled, a moment of hesitation can separate gold from silver. Research from Carnegie Mellon University helps explain why that split-second pause happens and how the brain controls it, offering insight not only into elite athletic performance, but also how people make everyday decisions when the outcome isn't clear.

Shift work and irregular eating patterns could affect liver function and disrupt its delicate circadian rhythm, University of Queensland researchers have found. Dr. Meltem Weger from UQ's Institute for Molecular Bioscience said the body has various circadian clocks that regulate critical biological processes including liver function. She said the liver operates its own body clock, releasing proteins in a 24-hour rhythm, and disruptions to this cycle are linked with chronic conditions such as obesity.
