Disinfectant used in water treatment may impact the incidence of Legionnaire's disease

Preliminary results of a nationwide study suggest that the disinfectant used to treat water before it is distributed through pipes may impact the incidence of Legionnaire's disease in certain parts of the country.

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.

Study uncovers how the body's bile acids bind to block C. diff's most dangerous toxin

In a major step towards a precision therapy for Clostridioides difficile (C. diff) infection, researchers at The Hospital for Sick Children (SickKids) have uncovered how the body's bile acids bind to block C. diff's most dangerous toxin.

Dietary restriction reprograms cancer-fighting immune cells to enhance anti-tumour immunity

Reducing calorie intake helps cancer-fighting immune cells do their jobs more effectively, reports a study by Van Andel Institute scientists and collaborators.

New study could lead to quicker and more targeted support for vulvodyniaia

A first-of-its-kind University of Stirling-led study could lead to quicker and more targeted support for vulvodynia - a painful chronic condition estimated to affect more than one in 10 women with no known cause.

New antibody shows ability to overcome treatment resistance in blood cancers and solid tumors

In a new preclinical study, researchers from The University of Texas MD Anderson Cancer Center developed an antibody therapy called 77A that showed an ability to overcome treatment resistance in blood cancers, such as myeloma and lymphoma, as well as solid tumors.

Australian researchers pinpoint specific genetic changes linked to severe AMD

Australian researchers have for the first time pinpointed specific genetic changes that increase the risk of severe, sight-threatening forms of age-related macular degeneration (AMD).

New study reveals productivity losses from substance use disorder in the U.S.

A new study shows that in 2023, substance use disorders led to nearly $93 billion in lost productivity in the United States from missed work, reduced job performance, inability to work, and lost household productivity.

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.

High BMI and poor physical fitness in adolescence linked to severe bacterial infections in adulthood

High BMI and poor physical fitness during later adolescence increase the risk of both contracting and dying from sepsis and other severe bacterial infections in adulthood, according to a study from the University of Gothenburg.

Physical activity may help restore ease of movement and agility during aging

The brain-chemical surge that comes with running may bolster coordination and speed in the old and young alike, a new study of middle-aged mice shows.

Study reveals how brain protein KCC2 influences reward learning

A new finding from researchers at Georgetown University Medical Center shows that the learning process of associating cues with rewards can be altered by increased or decreased activity of a specific protein in the brain.

Routine blood test may flag hidden osteoporosis risk, study finds

A large hospital-based cross-sectional study examined whether routinely measured serum alkaline phosphatase can indicate osteoporosis risk in adults undergoing health checks. Higher ALP levels, even within the normal range, were associated with greater osteoporosis likelihood, particularly in younger, female, and metabolically healthy individuals.

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.

A 36-week screening strategy safely reduces pre-eclampsia at term

Screening pregnant women at 36 weeks using a validated risk model and offering risk-stratified planned early-term birth reduced the incidence of term pre-eclampsia by about 30 percent without increasing maternal or neonatal complications. The randomised PREVENT-PE trial demonstrates that a personalised timing-of-birth strategy can prevent term pre-eclampsia where no effective medical prevention currently exists.

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.

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.

Older chemical libraries yield new leads for next-generation COVID-19 antivirals

SARS‑CoV‑2, the virus that causes COVID-19, continues to mutate, with some newer strains becoming less responsive to current antiviral treatments like Paxlovid.
