Anxiety and insomnia linked to reduced natural killer cell levels in young women

Natural killer (NK) cells are the bodyguards of our immune system. As a first line of defense, they destroy invading pathogens, foreign bodies, and infected cells in early stages, thereby preventing them from spreading.

Early warning for diabetes: AI model identifies prediabetes risk with high accuracy

A Scientific Reports study developed a pattern neural network that integrates total antioxidant status with clinical and metabolic markers to predict prediabetes in Indian adults. The model achieved very high accuracy and highlighted oxidative stress and waist circumference as key predictors, supporting earlier detection before progression to type 2 diabetes.

Researchers unravel why mRNA-based vaccines for COVID-19 can cause heart damage

Stanford Medicine investigators have unearthed the biological process by which mRNA-based vaccines for COVID-19 can cause heart damage in some young men and adolescents - and they've shown a possible route to reducing its likelihood.

Study offers a unified biological model to explain the causes of autism

A new University of California San Diego School of Medicine study offers a unified biological model to explain how genetic predispositions and environmental exposures converge to cause autism spectrum disorder (ASD).

Surprising new function of immune cells uncovered: Excess weight loss prevention

Researchers at the University of California San Diego School of Medicine have uncovered a surprising new function for immune cells: preventing excess weight loss.

Triaptosis could be a promising strategy in the fight against cancer

Cancer remains one of the most critical global public health challenges, exerting profound social, economic, and clinical burdens while limiting gains in human life expectancy.

Study shines new light on how cancer avoids the mitotic stopwatch pathway

When cell division (mitosis) takes too long, it can be a sign that something is wrong with the cells, for example DNA damage or chromosomal instability.

New arts and wellbeing program supports the social needs of families affected by dementia

A new arts and wellbeing program co-developed by the University of South Australia, Flinders University and the University of Adelaide shows that supporting the social needs of people living with dementia and their carers can help families rediscover connection, confidence and a sense of community.

SwRI and Trinity researchers work on next-generation intranasal therapy for PTSD

Southwest Research Institute (SwRI) and Trinity University are developing an intranasal (IN) drug-device combination to treat post-traumatic stress disorder (PTSD).

Nanoflower-treated stem cells deliver healthier mitochondria to stressed cells

This study shows that vacancy-engineered MoS₂ nanoflowers drive mitochondrial biogenesis in human mesenchymal stem cells by activating SIRT1–PGC-1α signaling and reducing oxidative stress. These treated cells transfer more functional mitochondria to injured recipient cells, restoring energy metabolism and redox balance in multiple in vitro models.

Landmark RSI trial reshapes sedative selection for emergency airway management

Doctors treating seriously ill patients in an emergency setting may want to give the sedative etomidate, rather than ketamine, while placing a breathing tube, according to a randomized trial published in the New England Journal of Medicine.

Brain function discovery helps explain why childhood adversity raises metabolic disease risk in women

McGill University researchers have identified a brain function that helps explain why childhood stress raises metabolic health risks for some women later in life.

Accuracy of remote photoplethysmography drops sharply at elevated heart rates

Researchers at Bielefeld University have analyzed how reliably AI methods can detect pulse rates from simple video recordings.

Supportive marriages may shape appetite control through oxytocin and the brain–gut axis

Supportive marital relationships are associated with lower BMI, fewer food addiction symptoms, higher oxytocin, stronger frontal brain responses to food cues, and favorable gut tryptophan metabolites. These coordinated social, neural, hormonal, and gut pathways suggest a plausible biological link between emotional support and healthier eating regulation.

Laughing gas shows fast antidepressant effects in early clinical trials

A systematic review and meta-analysis in eBioMedicine shows that nitrous oxide can rapidly reduce depressive symptoms within hours, particularly at higher doses, but effects are short-lived after single treatments. Repeated dosing appears to extend and strengthen antidepressant benefits, although the current evidence is based on small, early-phase trials with limited long-term safety data.

Why female athletes need injury prevention rules built for women, not men

This International Olympic Committee consensus synthesised evidence from over 600 studies to develop 56 injury prevention recommendations tailored to female, woman and girl athletes. It concludes that reducing injury risk requires a whole sports system approach that integrates training, policy, environment and culture, not exercise alone.

PTSD may be linked to accelerated brain aging among World Trade Center responders

Researchers from the Icahn School of Medicine at Mount Sinai have found that post-traumatic stress disorder (PTSD) may be linked to accelerated brain aging among World Trade Center (WTC) responders involved in rescue and recovery operations after the 9/11 terrorist attacks.

A North Carolina hospital was slated to open in 2025. Mired in bureaucracy, it’s still a dirt field.

Madison County, tucked in the mountains of western North Carolina, has no hospital and just three ambulances serving its roughly 22,000 people.

Social media affects children's ability to concentrate, study reveals

Children who spend a significant amount of time on social media tend to experience a gradual decline in their ability to concentrate.

Kiwifruit intake boosts vitamin C in skin and supports dermal structure

Study shows that increasing dietary vitamin C intake with kiwifruit raises vitamin C levels in both the dermis and epidermis through active transport from the bloodstream. Higher skin vitamin C levels were associated with increased skin density and epidermal cell proliferation, but not with improved UV protection or measurable increases in new collagen markers.
