D-serine promotes gastric cancer growth by suppressing tumor immunity

Researchers from Keio University have found that D-serine increases the growth of gastric cancer by creating an immunosuppressive and anti-inflammatory tumor microenvironment.

Nighttime light linked to conflicting signs of biological aging

Higher residential nighttime light exposure was associated with contrasting biological aging patterns in nearly 300,000 UK Biobank participants, depending on the aging algorithm used. PhenoAge and homeostatic dysregulation suggested a potentially adverse aging pattern, while KDM-BA showed the opposite association, underscoring uncertainty about how nighttime light relates to biological aging.

Parenting stress influences children's screen habits, study finds

Researchers at FIU have a message for parents: If screen time is part of getting through a stressful day, find a way to make it count. The goal should be to focus less on quantity and more on quality.

First-trimester protein intake linked to lower odds of small-for-gestational-age birth

A secondary analysis of 7,067 nulliparous participants found that first-trimester protein intake of 0.8 to less than 1.1 g/kg/day was associated with 22% lower adjusted odds of delivering an SGA infant than intake of at least 1.1 g/kg/day. The association was exploratory, with no dose-response pattern and no confirmation in sensitivity analyses.

ACLM launches first lifestyle medicine evidence repository for healthcare professionals

The American College of Lifestyle Medicine (ACLM) has launched the Lifestyle Medicine Evidence Repository, the first centralized, curated collection of scientific research focused specifically on lifestyle medicine interventions.

Biofortified millet improves toddler gut health without adverse effects

Toddlers who ate iron- and zinc-biofortified pearl millet for nine months did not experience adverse effects typically associated with increased iron intake and developed gut microbiomes with distinct and potentially beneficial changes, according to a new study led by researchers at Cornell University's Joan Klein Jacobs Center for Precision Nutrition and Health.

Inflammatory bowel disease linked to elevated risk of psychiatric disorders

Patients with inflammatory bowel disease (IBD) face a significantly higher risk of psychiatric disorders starting two to three years before diagnosis and lasting up to a decade after, according to a nationwide study to be published in Clinical Gastroenterology and Hepatology.

Mouse study shows how liraglutide briefly rewires gut bacterial communities

Researchers treated male high-fat-fed mice with liraglutide for 14 days, then tracked fecal bacterial communities after a 7-day washout using 16S rRNA sequencing. Liraglutide shifted the microbiome toward Lactobacillus- and Leptogranulimonas-related taxa while reducing several fermentative taxa, but most changes moved back toward baseline after treatment stopped.

NIH funds smartphone platform to improve driving safety for teens

Dr. Jeffrey Keller, Hibernia National Bank/Edward G. Schleider Endowed Chair at LSU's Pennington Biomedical Research Center, and Sara Seifert, president of Minnesota HealthSolutions, have received a new National Institutes of Health Small Business Innovation Research (SBIR) award to develop an innovative digital health platform that will help parents support teenagers with attention-deficit/hyperactivity disorder (ADHD) as they learn to drive.

Better sleep may boost academic and social success in adolescents

A new UC Davis Health study published in Psychological Medicine suggests that when it comes to helping adolescents succeed in school and maintain healthy friendships, sleep may matter more than screen time, exercise or diet.

Exercise helps protect Hispanic adults from late life cognitive decline

Previous studies have examined the associations between adherence to LS7 and cognitive outcomes, with findings suggesting that higher LS7 scores are associated with better cognitive performance, reduced dementia risk and improved brain health.

Study shows how solid food shapes immune system development

In a mouse model, LMU researchers have discovered a signaling pathway through which diet influences the development of the immune system.

Researchers suggest a potential therapeutic strategy for muscle loss associated with obesity

Obesity has been linked to skeletal muscle loss and deterioration. While M2 macrophages may play a role in regulating muscle function, the underlying mechanisms remain poorly understood.

Blood filtration method helps clear circulating lipids and toxic microplastics

The machine is not new. Some version of it has run in hospital treatment rooms for about four decades, drawing blood from one arm, separating out the plasma, passing it across a filter or an adsorber, and returning it to the other arm.

Continuous glucose monitors show no proven benefits for healthy people

Continuous glucose monitors are becoming increasingly popular, including among people without diabetes.

Food may taste different on GLP-1 drugs, but taste may not be the reason

The review suggests that patient-reported “taste changes” during GLP-1RA treatment may reflect reduced food enjoyment and motivation rather than consistent impairment of basic taste. The authors propose a sensory-liking-wanting framework while emphasizing that current human evidence remains heterogeneous and largely indirect.

Study links lower vitamin D to mood and cognitive health in adults over 85 with diabetes

Researchers studying 188 adults aged 85 years or older with type 2 diabetes found the lowest serum 25(OH)D concentrations among those with both depressive symptoms and mild cognitive impairment. Lower levels remained associated with having both conditions after adjustment for selected factors, but the cross-sectional study cannot establish causation or a benefit from supplementation.

Daily social connections may improve long-term health and cognition

Calling a friend after a long day. Showing up to a neighbor's dinner when you'd rather stay home. Lingering a little longer in a conversation that didn't need to last.

Restricting select amino acids may mimic protein restriction’s healthy aging benefits

A review finds that restricting protein, particularly methionine, isoleucine, and valine, may improve metabolism and influence key aging pathways, largely in experimental models. Short human studies suggest metabolic benefits, but effects on lifespan remain unknown and restriction may harm people with unmet or increased protein needs.
