Targeted mitochondrial therapy accelerates healing of diabetic chronic wounds

Impaired mitophagy and the accumulation of damaged mitochondria are key drivers of endothelial cell (EC)dysfunction in diabetic wounds.

Study reveals immune differences between titanium and zirconia implants

Zirconia is widely regarded as a promising alternative to titanium for bone and dental implants because of its aesthetic advantages, biocompatibility, and potential to reduce metal ion release.

Copper-based nanoplatform shows promise against metastatic tumor growth

What happens if cancer cells lose both their mitochondrial energy supply and their glycolytic backup system? This question is central to a new study published in Research by researchers from Northwestern Polytechnical University and collaborating institutions.

Exercise or caffeine? Study finds neither clearly beats placebo for mental fatigue

Researchers compare the effects of caffeine and aerobic exercise on mental fatigue in adults.

Tumors exploit peripheral nerves to support cancer growth and spread

Tumors do not communicate only with immune cells, blood vessels, and stromal tissue. A growing body of evidence suggests that cancer can also co-opt the nervous system, reshaping the tumor microenvironment in ways that support growth, invasion, immune escape, and therapeutic resistance.

Non-invasive swab test offers fast, accurate tuberculosis detection worldwide

A portable molecular test, MiniDock MTB, detected pulmonary tuberculosis rapidly and accurately across seven high-burden countries, using sputum or tongue swab samples. The study suggests the low-cost, battery-operated platform could expand near-point-of-care TB diagnosis in low-resource settings, although real-world implementation and drug-resistance integration still need evaluation.

Advanced 3D heart models could transform cardiovascular drug discovery

Cardiovascular disease remains a leading global health burden, yet many preclinical systems still struggle to predict how candidate drugs will perform in the human heart.

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.
