How Chemotherapy Triggers Nerve Damage, and How to Stop It

A new study reveals that chemotherapy-induced nerve pain arises from a stress response in immune cells that triggers inflammation and neurotoxicity. Researchers found that activating a cellular stress sensor called IRE1α causes nerve damage and pain during chemotherapy, but blocking it prevents both in mice.

Football Players Show Subtle Brain Differences Linked to CTE Risk

Brain scans of former football players revealed subtle differences in brain grooves compared to men who never played contact sports, possibly marking early signs of chronic traumatic encephalopathy (CTE). Researchers found that players had shallower grooves in a key frontal region previously associated with CTE and that years of play correlated with structural changes in another area of the brain.

Dopamine Boost Makes People More Patient

In one of the largest studies of its kind, researchers found that increasing dopamine levels with L-DOPA made people slightly more willing to wait for larger, delayed rewards—reducing impulsive decisions by about 20%. The study challenges earlier research suggesting that dopamine increases impulsivity, showing instead that it promotes patience and long-term thinking.

Gene That Controls How Sensitive You Are to Alcohol Discovered

Researchers have discovered that a gene called CHRNA3 plays a key role in determining alcohol sensitivity, helping explain why some people tolerate alcohol better than others. When this gene was mutated, subjects were slower to avoid alcohol and consumed more of it, showing reduced sensitivity to its calming effects.

Daily Light and Sound Therapy May Slow Alzheimer’s Decline

A long-term study found that daily 40Hz light and sound stimulation may help slow cognitive decline in people with late-onset Alzheimer’s disease. After two years of treatment, participants maintained stronger cognitive performance than typical Alzheimer’s patients and showed reduced levels of tau protein, a key disease biomarker.

Brain Cells That May Prevent Schizophrenia Symptoms Identified

Researchers have identified a rare type of brain cell whose overactivity may contribute to schizophrenia-like symptoms, such as cognitive deficits and disrupted sleep. When scientists reduced the activity of these cells in mice with a schizophrenia-linked mutation, the animals’ behavior and sleep patterns normalized.

Music and Nature Work in Harmony to Ease Stress and Lift Mood

The viral phrase “touch grass” may be more than internet humor—science shows that engaging with nature and music can significantly boost emotional and physical well-being. A new review found that combining these experiences—such as listening to music outdoors, gardening while singing, or caring for animals—can improve mood, reduce stress, and ease symptoms of anxiety and depression.

Listening to Music After 70 May Cut Dementia Risk by Nearly 40%

Older adults who regularly listen to or play music may significantly lower their risk of dementia, according to a study of more than 10,800 people over age 70. Those who always listened to music showed a 39% lower risk of developing dementia and better memory performance, while those who played instruments had a 35% lower risk.

Alzheimer’s Disrupts Brain’s Internal Clock, Unraveling Gene Rhythms

Alzheimer’s disease not only damages memory but also distorts the brain’s internal clock, disrupting the daily rhythms of hundreds of genes tied to brain health. Researchers found that in mice with amyloid buildup, normal circadian gene activity in microglia and astrocytes—the brain’s immune and support cells—became erratic.

Swap 30 Minutes of Sitting for Light Activity to Boost Next-Day Mood

New research reveals that replacing even 30 minutes of sitting with light physical activity—like walking or doing household chores—can boost mood and energy the following day. The study tracked over 350 young adults using wearable monitors to assess daily movement patterns.

Pain Resilience, Not Pain Itself, Predicts How Active People Stay

A new study reveals that how people think about and cope with chronic pain is more important than the pain itself in determining physical activity levels. Researchers found that individuals with higher pain resilience — the ability to maintain positive functioning despite pain — were significantly more active than those with lower resilience.

Lack of Sleep in Teens Linked to Higher Suicide Risk

Teenagers who sleep less or experience frequent night awakenings are significantly more likely to attempt suicide later in adolescence, according to a major longitudinal study. Researchers analyzed data from more than 8,500 teens and found that poor sleep at age 14 predicted suicide attempts by age 17, even after accounting for other mental health risk factors.
