Could a fingerprick at home flag your Alzheimer's risk? New study says yes

Researchers demonstrated that self-administered fingerprick blood tests measuring p-tau217 and GFAP, returned by post, correlate strongly with venous blood biomarkers and cognitive performance across the Alzheimer's disease continuum. Combined with computerized cognitive testing, this at-home approach offers a scalable, patient-friendly tool for triaging individuals at risk of AD-related impairment.

Do repeated football head hits disrupt the gut microbiome?

A small exploratory study of collegiate football players found that non-concussive head impacts are correlationally linked to acute and season-long shifts in gut microbiome composition, with changes most pronounced 48–72 hours after significant impacts. However, most associations weakened after correction for multiple testing, and the authors stress the findings are preliminary and hypothesis-generating.

What drives adult ADHD symptoms? Study points to executive function over environment

Adults diagnosed with ADHD later in life had fewer childhood symptoms than those diagnosed in childhood, but both groups showed similar symptom severity in adulthood. Executive function, rather than childhood trauma, resilience, or parental bonding, was the strongest correlate of current ADHD symptoms across both diagnostic-history groups.

Liver fat may disrupt post-meal glucagon control in early type 2 diabetes

Researchers found that MASLD, rather than type 2 diabetes alone, was linked to higher fasting glucagon levels in adults with newly diagnosed diabetes and matched controls. In people with early type 2 diabetes, higher liver fat was specifically associated with exaggerated early post-meal glucagon responses, independent of insulin sensitivity, visceral fat, amino acids, or NEFAs.

Can meditation backfire? Study finds brief mindfulness may heighten stereotype bias

Mindful meditation may not only fail to reduce cognitive bias but, based on the study findings, may exacerbate stereotypes.

Lab-grown diamonds enable highly-sensitive radiation dose measurements

A team led by researchers from Tokyo Metropolitan University, in collaboration with Tohoku University and Orbray Co., Ltd., using heteroepitaxial diamond materials developed by Orbray, have shown that lab-grown diamonds might realize a radiation dosimeter compatible with both medical diagnosis and radiation therapy.

Sexual arousal can blur recognition of unclear rejection signals

Sexual arousal can lead to "tunnel vision" that makes it more difficult to recognize when someone is just not that into you, according to new research in Personality and Social Psychology Bulletin.

Researchers uncover how bacterial toxin damages colon lining cells to trigger cancer

Since a landmark 2009 study, researchers have known that a common gut bacterium, Bacteroides fragilis, drives colon tumor formation, potentially leading to colorectal cancer, by secreting a toxin that damages the lining of the colon.

Bioinspired artificial muscle filaments bend and twist with temperature changes

Nature is replete with slender filaments that bend and coil – from climbing grape vines, to folded proteins, to elephant trunks that can pick up a peanut but also take down a tree.

Plant-based mosquito repellent offers effective alternative to DEET lotions

Summertime hikes and afternoons in the backyard can be ruined by mosquito bites. So, many people apply topical synthetic repellents like DEET before heading outside, but there is a growing market for natural repellants that could be less irritating to the skin and more environmentally friendly.

Scientists uncover cellular mechanism behind rare childhood brain disorders

Thousands of times per year, a family's moment of joy turns to unexpected grief. A seemingly healthy infant stops smiling or making eye contact.

Study challenges assumptions about testosterone’s role in brain cancer

Scientists have long suspected that androgens, male sex hormones like testosterone, may help tumors grow because the hormones can suppress immune responses to some cancers.

A brain-based approach may improve smoking cessation treatment success

For many people who smoke, quitting is not just a matter of willpower. It is a tug-of-war in the brain – between the pull of reward and the ability to resist.

New brain findings open pathways for understanding behavioral and neurological disorders

When danger lurks, instinct keeps us safe. It compels us to run from a burning building or wrestle a knife-wielding attacker to the ground. It also adjusts our body physiology to support these behaviors.

Engineered regulatory T cells offer a path toward immunosuppression-free transplants

Organ transplantation remains the cornerstone treatment for end-stage organ failure. While conventional broad-spectrum immunosuppression effectively controls acute rejection, it fails to address chronic rejection and carries long-term side effects including infection, malignancy, and metabolic disorders.
