Vitamin D Supplementation Slows Cellular Aging

A large 4-year randomized trial found that daily vitamin D3 supplements help slow the shortening of telomeres in healthy older adults. Participants taking 2,000 IU of vitamin D3 lost around 140 fewer base pairs than those on placebo.

Cold Sore Virus Linked to Higher Alzheimer’s Risk

A US study suggests that symptomatic infection with herpes simplex virus type 1 (HSV-1), the virus that causes cold sores, may increase the risk of Alzheimer’s disease. People treated with antiviral drugs had a lower risk.

Blood and Urine Biomarkers Reveal How Much Ultra-Processed Food We Eat

A study from the U.S. National Cancer Institute developed poly-metabolite scores based on metabolites in blood and urine to measure ultra-processed food (UPF) intake. This method offers a more reliable alternative to self-reported diet data.

Stabilized, Not Shut Down: What Ketamine Really Does to the Brain

Research reveals that ketamine stabilizes brain activity in a dose-dependent way. The study used high-density EEG to track changes in brain stability, suggesting ketamine’s effects on brain dynamics might be central to its therapeutic use.

How ADHD and Obesity Are Linked – And Why City Living Might Help

A study shows that ADHD can increase obesity risk through impulsive behaviors and biological pathways. The study highlights how urban environments, including access to mental health services and food insecurity, shape this link.

Carbohydrate Choices in Midlife Affect Aging Outcomes

A 30-year study of 47,000 women found that consuming high-quality carbohydrates and fiber during midlife improves odds of healthy aging. Diets rich in whole grains, fruits and vegetables supported better physical and cognitive health.

Biomarkers Reveal Neurological Basis for Long COVID

A pilot study comparing people with and without long COVID symptoms found differences in brain inflammation and recovery signals. People with long COVID had more fatigue and anxiety, lower nerve growth factor and signs of ongoing immune activity.

Why a Mutation in Ginger Cats Might Explain Both Color (and Chaos)

A Stanford-led study has identified a mutation on the X chromosome that causes orange fur in cats. The mutation switches on the normally silent Arhgap36 gene in pigment cells, blocking black/brown pigment production.

Why Do We Keep Doing Things That Don’t Feel Rewarding?

UCL researchers have discovered a second dopamine-based learning system in the brain that reinforces repeated actions without regard to outcome. This “action prediction error” signal helps form habits and may explain why certain behaviors persist.

Endometriosis May Double Risk of Premature Menopause

A large study found that women with endometriosis are at an increased risk of experiencing early or surgical menopause. Surgical menopause occurred 19 months earlier, while natural menopause happened 5 months earlier.
