Why Chewing Feels So Good to Your Brain

New research reveals that gnawing isn't just a reflex—it’s a brain-rewarded behavior that keeps jaws aligned and pleasure centers firing.

Lifetime Lead Exposure Triples Alzheimer’s Risk

Think lead is a problem of the past? New research shows that lead stored in your bones for decades could triple your risk of Alzheimer’s disease. By tracking thousands of adults, scientists have discovered that historical exposure to leaded gas and paint is a "silent" driver of nearly 1 in 5 dementia cases.

High Pollen Levels Tied to Rising Suicide Risk

A U.S. study combining pollen and suicide data from over a decade shows that high pollen days are linked to a measurable rise in suicide risk. The risk increased incrementally with pollen levels, peaking at a 7.4% rise on the highest days.

Human Stem Cell Transplants Boost Vision in Advanced Dry AMD

A new clinical trial suggests stem cell therapy may restore vision in people with advanced dry age-related macular degeneration, a disease that currently has no cure. Researchers transplanted retinal pigment epithelial stem cells, derived from adult postmortem eye tissue, into patients’ eyes.

Dietary Intervention Could Slow Deadly Brain Cancer Growth

A new study reveals that glioblastoma, the most aggressive brain cancer, thrives by using sugar in unique ways that differ from healthy brain cells. While normal brain tissue channels sugar into energy and neurotransmitters, glioblastoma cells divert it into producing DNA and RNA, fueling relentless tumor growth.

Brain Rewiring Patterns May Predict Alzheimer’s Years in Advance

Researchers have discovered that people with Alzheimer’s show unusually high neural flexibility—the constant reorganizing of brain networks—even while resting. In a large study of older adults, higher neural flexibility in the visual network predicted which healthy participants would later develop dementia.

Nighttime Brain Activity Keeps Glucose Levels in Check

A new study reveals that the brain actively maintains blood sugar stability during everyday life, not just during crises. Researchers identified VMHCckbr neurons in the hypothalamus that regulate glucose by promoting fat breakdown, especially during the early hours of sleep.

How Cool Touch Travels From Skin to Brain

A groundbreaking study has mapped the full neural circuit that carries cool temperature signals from the skin to the brain. The pathway begins with molecular sensors in the skin, which activate neurons that send signals to the spinal cord, where the message is amplified before reaching the brain.

Sleep’s Secret Sequence May Sculpt Our Memories Like a Garden

A new theory suggests that the order of sleep phases—non-REM followed by REM—is essential for strengthening and organizing memories. In mice studies and computational models, researchers found that non-REM sleep reinforces new memories, while REM sleep prunes overlapping or irrelevant ones, keeping them distinct.

Seasonal Sunlight Still Shapes Human Sleep

Despite modern lighting and lifestyle, human sleep patterns remain deeply influenced by seasonal changes in sunlight. New research reveals that our circadian rhythms track daylight shifts across seasons, impacting mood, sleep alignment, and overall health.

Personality Could Help Predict Bipolar Disorder

New research suggests that personality testing could help tailor treatment for people with bipolar disorder by predicting who is more likely to experience recurrent depression or struggle with daily life functioning. Analyzing data from over 2,500 individuals, researchers identified combinations of personality traits—called personality styles—that either increase or protect against long-term mental health risks.

When to Talk Puberty: Parents Split on Best Timing

A national survey reveals that while most parents recognize the importance of discussing puberty, many are uncertain about when or how to start the conversation. Roughly half of parents prefer a proactive approach, while others wait until children ask questions—or avoid the topic altogether.
