SARS-CoV-2 rarely reaches first-trimester placentas but still disrupts early pregnancy immunity

Researchers analyzing 761 first-trimester pregnancies found that SARS-CoV-2 was rarely detected in placental tissues, suggesting in utero transmission early in pregnancy is uncommon. However, maternal infection was linked to immune dysregulation at the maternal-fetal interface, altered trophoblast signaling, and inflammatory changes that could affect placental development.

Common osteoporosis drugs could slow or halt aneurysm progression

Aortic aneurysms are characterized by abnormal enlargement of the aorta, the primary artery responsible for carrying blood from the heart. Rupture often leads to sudden death, and currently, no effective drug therapies are available to halt disease progression.

Study finds when parents are depressed may shape children’s mental health for decades

A long-running UK cohort study found that exposure to parental depression from pregnancy through young adulthood was linked to higher odds of depression and anxiety in adult offspring. Maternal depression in late pregnancy was uniquely associated with later psychotic symptoms, while paternal associations emerged more clearly from mid-childhood onward.

States change custody laws to keep children of detained immigrants out of foster care

As immigration authorities carry out what President Donald Trump has promised will be the largest mass deportation operation in U.S. history, several states are passing laws to keep children out of foster care when their detained parents have no family or friends available to take temporary custody of them.

A new model to break the cycle of chronic nightmares in children

The DARC-NESS model targets chronic nightmares in youth, promoting confidence and coping strategies to restore healthy sleep patterns and mental well-being.

Very high prenatal PFAS exposure increases childhood asthma risk

High prenatal exposure to PFAS linked to increased childhood asthma risk, highlighting concerns over 'forever chemicals' and early-life environmental impacts.

Microplastics lab studies may fail to reflect real-world exposure

Microplastics pose health risks, but lab studies often fail to reflect real-world exposure, highlighting critical gaps in toxicological research methodologies.

Study finds top AI models still struggle with clinical reasoning

Researchers tested 21 frontier large language models on 29 stepwise MSD Manual clinical vignettes and found that, although many models performed well on final diagnosis, they remained much weaker at differential diagnosis and diagnostic testing. They also introduced the PrIME-LLM score, a multidimensional benchmark designed to better capture balanced clinical reasoning across the full workflow rather than raw accuracy alone.

Study warns of rising teen dependency on AI companions

It's estimated that more than half of all of U.S. teens are regularly using companion chatbots powered by large language models and generative artificial intelligence (AI) technology.

New method boosts AI-driven protein engineering with massive data

Protein engineering is a field primed for artificial intelligence research. Each protein is made up of amino acids; to optimize a protein function, researchers modify proteins by switching out one of 20 different amino acids for another.

Generative AI falls short in diagnostic reasoning despite accuracy

Despite increasing use of artificial intelligence (AI) in health care, a new study led by Mass General Brigham researchers from the MESH Incubator shows that generative AI models continue to fall short at their clinical reasoning capabilities.

Categorization is fundamental and predictive across all brain processing

Challenging the classic view, two cognitive scientists argue in a new review that categorization is not a late, specialized stage of sensory processing.

Alzheimer's risk gene APOE4 impacts bone health in females

Scientists at the Buck Institute for Research on Aging, along with collaborators at UC San Francisco, have discovered that APOE4, the most common genetic risk factor for Alzheimer's disease, causes bone quality deficits specifically in female mice, through a mechanism that is invisible to standard imaging and can emerge as early as midlife.

Prenatal opioid exposure shows minimal effect on later academic performance

Every 25 minutes in the United States, a baby is diagnosed with neonatal abstinence syndrome (NAS), a condition that occurs in newborns who have been exposed to opioids in the womb and develop withdrawal after birth, according to the Centers for Disease Control and Prevention.

Supportive neighborhoods linked to slower cognitive decline in older immigrants

Older Chinese immigrants living in neighborhoods with greater access to community amenities, services and supportive infrastructure experienced slower cognitive decline over time, according to Rutgers Health researchers.

Postpartum Medicaid expansion improved coverage but showed limited care changes

The federal policy requiring states to keep Medicaid beneficiaries enrolled during the COVID-19 pandemic extended postpartum Medicaid coverage nationwide and sharply increased the number of individuals remaining insured after childbirth, according to a Rutgers Health researcher.

Prostate cancer patients recover faster with TULSA than robotic surgery

A new randomized clinical trial found that men with localized, intermediate‑risk prostate cancer recovered faster and experienced less short‑term impact on their daily lives when treated with MRI‑guided, transurethral ultrasound ablation (TULSA) compared with robotic prostate surgery.

Vaping may raise cognitive impairment risk in young adults, study finds

A cross-sectional study of 232 young adults in Bangkok found that e-cigarette users were more likely than non-smokers to screen as at risk for cognitive impairment on the MoCA, while no significant differences were seen for ADHD symptom tendency or emotional intelligence. The authors say the findings raise neurocognitive concerns but do not prove causation, and they call for longitudinal research to clarify whether vaping contributes to later cognitive decline.

Beetroot supplement raises nitric oxide markers in triathletes after one week

A randomized cross-over pilot study in 10 amateur male triathletes found that a beetroot-based multi-ingredient nitrate supplement increased nitric oxide-related and redox biomarkers over 7 days without evidence of lipid oxidative damage. The supplement was generally well tolerated, but the study did not measure whether these biochemical changes improved performance or recovery.

Study shows why an apple a day may work differently for different people

A 12-week single-blind trial in 38 Japanese adults found that daily Fuji apple intake did not significantly change overall host metabolic markers, but responses differed by baseline gut enterotype. Participants in the Bacteroidaceae-dominant enterotype showed significant increases in fecal short-chain fatty acids after apple consumption, suggesting that gut microbiota structure may shape functional dietary responses.
