🔬 First-Ever Contagious Cancer Found in Freshwater Fish — Plus: The Math Formula That Predicts Relationship Doom

Scientists have identified the first known transmissible cancer in a freshwater animal — and it's spreading among catfish in ways that have researchers racing to understand the mechanism. A landmark clinical trial found that a THC and CBD combination significantly reduced agitation in late-stage dementia patients, offering a rare glimmer of hope for one of the condition's most difficult symptoms. New research reveals that chronic sleep disorders may be physically restructuring key regions of the brain, while decades of financial hardship have been linked to measurable acceleration in brain aging by midlife. Mathematicians claim three decades of data have produced models that can identify 'danger zones' in romantic relationships — and the findings are more rigorous than you might expect. Rounding out the episode: a breakthrough in aging research targets so-called zombie cells, prescribed burns are proving critical to saving giant sequoias, and scientists have found a way to store light inside a fiber frozen to nearly -200°C.Subscribe to Peer Review'd Newsletter: https://peerreviewd.com/Love Science?
