AI is helping reveal how the brain flushes out toxic waste while we sleep.
A study published in Science Advances used AI to map the fluid flow velocity of the brain’s glymphatic system—the essential nightly “rinse cycle” that clears away metabolic proteins linked to Alzheimer’s disease. It shows that waste clearance moves via two distinct speeds — a fast track around open surface regions and a trickle through deep tissue that is 50 times slower. Researchers hope this information helps create more non-invasive screening tools to identify poor brain circulation.
The mystery of chronic itch may finally be traced back to the finest hairs on your skin.
A study published in the Journal Neuron reveals that the short, fine hairs we think of as peach fuzz on our skin are wired to sensitive neurons dedicated strictly to transmitting mechanical itching sensations. While typical treatments effectively soothe chemical irritations like mosquito bites, they completely fail against this pathway. Researchers hope this finding helps create more effective therapies for chronic itch.
An herbal supplement marketed as a safe, natural remedy is quietly sparking a major public health crisis among young Americans.
According to a national study in the Journal Of Addiction Medicine, lifetime use of kratom rose significantly between 2021 and 2024, impacting more than 100 thousand children aged 12 to 17. Researchers found an alarming correlation between kratom use and severe psychiatric distress, major depression, and poly-substance use disorders. The study underscores an urgent need for state regulations to protect vulnerable minors.
The secret to conquering mosquito season might be sitting right in your pantry.
A study published in the American Journal Of Clinical Nutrition found that high-quality whey protein powder is consistently outperformed by a variety of physical strength exercises. Extra protein intake yielded absolutely no change in muscle strength or functional mobility. So for healthy seniors already consuming the recommended daily allowance of nutrients, protein shakes alone are no substitute for the vital mechanical stress of regular exercise.
