Why vitamin B6 could raise the risk of hypoglycemia for people with diabetes

A large-scale Mendelian randomization study found no genetic evidence that vitamins A, C, or D reduce the risk of major diabetic complications. However, higher genetically predicted vitamin B6 levels were strongly associated with increased risk of diabetic hypoglycemia, warranting caution with supplementation.

Twin study reveals genetic influence on infant crying and sleep

How much an infant cries is largely steered by their genetics and there is probably not much that parents can do about it.

Circadian misalignment in the blind may impact daily brain functions

This study investigates how blindness affects sleep, dreams, and spatial awareness, revealing links between circadian rhythms and cognitive performance.

Study provides a molecular snapshot of Tanshi constitution's immunological landscape

The study aims to uncover the immunological basis of Tanshi (phlegm-dampness) constitution—a subhealth type in traditional Chinese medicine (TCM)—using single-cell RNA sequencing (scRNA-seq) of peripheral blood mononuclear cells (PBMCs).

Bayesian neural networks advance understanding of gut microbe metabolism

Gut bacteria are known to be a key factor in many health-related concerns. However, the number and variety of them is vast, as are the ways in which they interact with the body's chemistry and each other.

$Ten-year study tracks trends in pediatric clavicle fractures across the U.S.$

Ten-year study tracks trends in pediatric clavicle fractures across the U.S.

Clavicular fractures are common injuries among children, usually due to sports-related trauma or accidental falls. The purpose of this study was to assess the epidemiology of clavicular fractures among children in the United States between 2014 and 2023.

Teen drivers spend over one fifth of each trip distracted by phones

A new study offers a stark reminder of how pervasive cell phone use while driving is for young people, as findings demonstrate teen drivers spend an average of 21.1% of each trip viewing their mobile behind the wheel.

Are you at risk? Waist size, not weight, could affect fertility in women

Researchers found that higher relative fat mass (RFM), a measure of visceral body fat, is significantly associated with increased infertility risk in U.S. women aged 20–44. The study suggests RFM may be a more sensitive screening tool for infertility risk than traditional BMI, especially in women with normal weight but high visceral fat.

Survey: Many adults unaware of key facts that can help prevent SIDS

Sudden infant death syndrome (SIDS) is the unexpected, unexplained, sudden death of a child younger than one year old.

Study reveals high rates of distracted driving among teenagers

A new study from Mass General Brigham researchers offers a stark reminder of how pervasive cell phone use while driving is among young people.

Why afternoon sunlight could be keeping your teen awake at night

Bright afternoon and early evening light exposure in adolescents leads to lower melatonin levels and delays circadian rhythms, instead of protecting against evening light effects. Long-term light history, especially morning exposure, may help align adolescent sleep cycles.

Poor lifestyle habits nearly double your chance of developing AFib

A large Framingham Heart Study analysis found that adults with poor cardiovascular health scores on the Life’s Essential 8 were nearly twice as likely to develop atrial fibrillation as those with ideal scores. Maintaining healthy lifestyle habits, especially optimal BMI, blood pressure, and glucose, may help reduce AF risk.

Looking for a natural way to lower blood pressure? Whole grains might be the answer

A new meta-analysis of prospective cohort studies found that higher whole grain intake is linked to a significantly lower risk of developing hypertension, with a 26% risk reduction observed between highest and lowest intake groups. In contrast, refined grain consumption showed no clear association with hypertension risk.

Targeting a key enzyme could reverse early Parkinson's effects

Putting the brakes on an enzyme might rescue neurons that are dying due to a type of Parkinson's disease that's caused by a single genetic mutation, according to a new Stanford Medicine-led study conducted in mice.

New brain scan tool predicts aging speed and dementia risk

Any high school reunion is a sharp reminder that some people age more gracefully than others. Some enter their older years still physically spry and mentally sharp. Others start feeling frail or forgetful much earlier in life than expected.

Is lactose intolerance secretly stealing your restful sleep?

Researchers surveyed over 1,000 university students and found that lactose intolerance, especially when accompanied by gastrointestinal symptoms, is linked to more frequent nightmares and poor sleep. Only a small minority reported that food affected their dreams, highlighting a specific risk for those with food sensitivities.

Why exercise is key for keeping slim after you quit smoking

Quitting smoking is linked to greater long-term waist circumference gain, but this effect may be due to shared genetics rather than quitting itself. Increased physical activity consistently helped limit waist expansion across all genetic backgrounds.

Spaceflight exposes astronauts to hidden threats in their gut

This review highlights how the unique stressors of space travel, radiation, microgravity, and circadian disruption impact astronauts’ gut microbiomes, with potential consequences for their mood, cognition, and immunity. The authors call for targeted microbiome monitoring and dietary interventions to protect astronaut mental health on future missions.
