Cortisol Kill-Switch: Exercise Rewires Stress Biology
A first-of-its-kind one-year clinical trial proves that 150 minutes of weekly aerobic exercise significantly lowers long-term cortisol levels and slows brain aging.
Noise is the Signal: Why Weak Brain Connections Predict Behavior
Researchers have discovered that the 90% of brain signals usually ignored as “noise” can predict behavior just as accurately as the strongest signals, revealing a much more complex “hidden iceberg” of neurobiology.
Could Alzheimer’s Begin in the Nerves, Not the Brain?
Researchers using “human-on-a-chip” technology have found that Alzheimer’s-related movement issues may start in the peripheral nerves, rather than the brain, offering a new path for early diagnosis.
The Destroyed Remnants of a Lost World Are Falling to Earth, Scientists Discover
A rare class of meteorites called angrites likely come from a strange protoplanet that was catastrophically destroyed in the early solar system, leaving only fragmentary remnants.
Entire Animal Kingdom Communicates at the Same Tempo
Species from fireflies to humans communicate at a shared tempo of 2 hertz. This “universal beat” matches the natural processing speed of animal brains.
Stressed Out? Diverse Gut Bacteria Might Be to Blame
High gut microbial diversity is associated with stronger, more flexible stress responses in humans, highlighting the role of bacterial metabolites like butyrate and propionate.
