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.

Hotter days and nights are already stealing sleep across the U.S.

Rising nighttime and daytime temperatures are associated with reduced sleep duration, poorer sleep continuity, delayed sleep onset, and altered sleep stages in a large U.S. cohort tracked with wearable devices. Vulnerability is greatest among adults aged 40–50 years, females, people with lower socioeconomic status, chronic conditions, and those living in marine climate zones, with climate change projected to further magnify sleep loss.

Everyday PFAS exposure alters placental function in early pregnancy

This study measured real-life PFAS concentrations in first-trimester human placentas and used these data to create a pregnancy-relevant PFAS mixture. In 3D trophoblast spheroid models, the mixture altered invasion, hormone secretion, and gene expression without broadly reducing viability at environmentally relevant doses.

Early RSV infection turns maternal allergy into a powerful driver of childhood asthma

Early-life RSV infection and parental allergy interact to substantially increase childhood asthma risk, supported by population data from more than 1.5 million children and mechanistic mouse experiments. The study shows that viral infection reprograms neonatal immune responses by altering how maternally transferred allergen-specific antibodies are handled, driving long-term allergic airway disease.

Genome-edited immune cell therapy shows promise for treating aggressive blood cancer

A groundbreaking new treatment using genome-edited immune cells, developed by scientists at UCL (University College London) and Great Ormond Street Hospital (GOSH), has shown promising results in helping children and adults fight a rare and aggressive form of blood cancer called T-cell acute lymphoblastic leukemia (T-ALL).

Powerful prognostic marker could enable early identification of high-risk cancer patients

Aggressive T-cell lymphoma is a rare and devastating form of blood cancer with a very low five-year survival rate.

Industrial and farm chemicals quietly alter the balance of gut microbes

This study systematically screened over 1,000 agricultural and industrial chemicals and found that many can inhibit human gut bacteria in vitro. Beyond antimicrobial effects, these chemicals act as selective pressures that can reshape microbial competition, tolerance mechanisms, and metabolic pathways.

Lymphocyte levels help predict outcomes after CAR T-cell therapy in non-Hodgkin lymphoma

Measuring the lymphocytes - white blood cells that fight infection - in a patient's blood can be used to predict outcomes in non-Hodgkin lymphoma patients who receive CAR T-cell therapy, according to research from physicians at Fox Chase Cancer Center and Temple Health.

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.

Poor dietary iron weakens lung memory T cells after flu infection

Dietary iron deficiency in mice alters lung T cell activation during influenza infection and leads to memory T cells that are present in normal or increased numbers but have impaired antiviral cytokine responses. These functional deficits are most pronounced in lung CD8-positive memory T cells and persist even under optimal recall conditions.

Timing of genetic mutation dictates childhood leukemia aggressiveness

A team of researchers at the Icahn School of Medicine at Mount Sinai has uncovered why children with the same leukemia-causing gene mutation can have dramatically different outcomes: it depends on when in development the mutation first occurs.

Researchers explore brain activity linking nicotine withdrawal and pain sensitivity

Abstinent smokers experience increased pain sensitivity during withdrawal, to the point that they often require more pain relief after surgery.

Insufficient sleep may decrease life expectancy

A good night's sleep is more than a luxury: New research from Oregon Health & Science University suggests that insufficient sleep may shorten your life.

Intellicule secures $217,941 SBIR Phase I grant to develop biomolecular modeling software

Intellicule, a software company whose solutions determine the 3D structures of biomolecules imaged with cryogenic-electron microscopy (cryo-EM), has received a $217,941 Small Business Innovation Research (SBIR) Phase I grant from the National Institutes of Health.

Researchers discover a surprising ally in the fight against insulin resistance and type 2 diabetes

An international research team led by Professor Marc-Emmanuel Dumas at Imperial College London & CNRS together with Prof. Patrice Cani (Imperial & University of Louvain, UCLouvain), Dr. Dominique Gauguier (Imperial & INSERM, Paris) and Prof. Peter Liu (University of Ottawa Heart Institute) has uncovered a surprising ally in the fight against insulin resistance and type 2 diabetes: a microbial metabolite called trimethylamine (TMA).

Novel wireless device uses light to send information directly to the brain

In a new leap for neurobiology and bioelectronics, Northwestern University scientists have developed a wireless device that uses light to send information directly to the brain - bypassing the body's natural sensory pathways.

JAX wins $30 million contract to create computational "digital twins" of the human heart

Developing new drugs is one of the riskiest and most expensive endeavors in science. Today, The Jackson Laboratory (JAX) announced a bold initiative to improve that trajectory, powered by an up to $30 million contract from the Advanced Research Projects Agency for Health (ARPA-H) Computational ADME-Tox and Physiology Analysis for Safer Therapeutics (CATALYST) program.

Sleep may hold the key to staying active

Getting enough sleep and staying active are two of the most important things we can do for our health, but new research shows that most people struggle to achieve both, and that sleep may hold the key to moving more.

Noninvasive Raman device tracks blood glucose accurately in under a minute

MIT researchers developed a compact band-pass Raman spectroscopy device that noninvasively tracks glucose through the skin in under a minute using physically interpretable optical signals. In a pilot study and tissue phantom validation, the system showed glucose measurements comparable to commercial continuous glucose monitors, supporting further clinical evaluation.

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.
