Heated tobacco products cause immediate cardiovascular and genetic damage

Just one session of heated tobacco product use results in measurable damage to the blood vessels, according to a study published today (Tuesday) in the European Journal of Preventive Cardiology.

Study reveals how cancer cells survive chemotherapy in a zombie-like state

Scientists at Trinity College Dublin have made an important breakthrough in understanding how cancer cells can evade the cell-killing effects of chemotherapy and enter a "zombie-like state", called premature senescence, that can attract the wound healing properties of the immune system.

Maternal stress alters placental pathways affecting fetal brain development

About one in five U.S. women experience maternal mental health conditions, and chronic stress during pregnancy can contribute to risk for both maternal and child health challenges.

How microplastics and bacteria interact to drive antibiotic resistance

Microplastics can change how bacteria form biofilms and develop antibiotic resistance. Maria Jazmin Silvero Compagnucci explains.

Half-matched bone marrow transplants show high survival in young aplastic anemia patients

Researchers at the Johns Hopkins Sidney Kimmel Comprehensive Cancer Center and Johns Hopkins Children's Center report that bone marrow transplant using half-matched family donors achieved a 96% survival rate among children, adolescent, and young adult patients with severe aplastic anemia, a rare, life-threatening disorder in which the bone marrow fails to produce enough healthy blood cells.

Global study aims to map brain changes across eight psychiatric disorders

Researchers from the Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC will lead a worldwide effort to map how eight common psychiatric disorders affect brain function, supported by a five-year, $3.2 million grant from the National Institutes of Health.

Scientists discover immune pathway behind radiation-induced lung damage

Researchers at City of Hope®, one of the largest and most advanced cancer research and treatment organizations in the country, have uncovered an immune pathway that may contribute to radiation-related lung damage and have identified a potential strategy to block it.

Researchers use mitochondrial uncouplers to target breast cancer metastasis

Mitochondrial serine catabolic pathway (MSCP), also called serine, glycine, and one-carbon metabolism, is essential for cancer cells to produce amino acids, one-carbon units, and reducing equivalents.

Blood pressure drug losartan boosts metabolism by stimulating brown fat

Losartan, a drug commonly prescribed for high blood pressure, boosts brown adipose tissue or "brown fat" activity and enhances its metabolism, according to a preclinical study by Weill Cornell Medicine, Rockefeller University and Memorial Sloan Kettering Cancer Center researchers.

Study reveals mature immune functions in embryonic neutrophils

Neutrophils are white blood cells that form part of the body's first line of defence. Researchers have now demonstrated for the first time that neutrophils are found in many tissues during embryonic development, and that they can perform the same functions as adult neutrophils.

Cannabis users face increased heart attack risk around surgery

As marijuana use becomes more common and legal in most U.S. states, patients who use cannabis may face a significantly higher risk of heart attack around the time of surgery, while also showing an unexpected lower risk of dangerous blood clots in the veins, suggests a study presented at the ANESTHESIOLOGY® 2026 annual meeting.

Postoperative monitoring apps reduce emergency visits and complications

Mobile app-based monitoring may help address the vulnerable days and weeks after surgery when recovery shifts from the hospital to home with little direct supervision.

You don't need 10,000 steps a day to benefit your heart, cardiologists say

A new American College of Cardiology scientific statement recommends integrating individualized exercise prescriptions into routine cardiovascular care, drawing on evidence supporting aerobic activity, resistance training, and cardiac rehabilitation. The authors emphasize that previously inactive individuals have the most to gain from increasing physical activity, while exercise recommendations should consider individual health conditions, functional capacity, and safety.

AI study of 101,000 patients links brown fat to heart and mental health

In a retrospective analysis of PET-CT records from 101,243 patients, researchers found that detectable brown fat was associated with lower prevalence of cardiometabolic and psychiatric conditions, while greater activity, particularly in the axillary region, was linked to more favourable metabolic outcomes. Medication screening identified losartan, which increased brown fat thermogenic activity in laboratory experiments and energy expenditure in mice, although its effects on human brown fat remain unproven.

Scientists discover water-triggered reactions that may explain microplastic harm

Researchers found that six common types of microplastics spontaneously generate reactive oxygen species at their interfaces with water, with more hydrophobic plastics showing greater chemical activity. Laboratory experiments also linked these surface properties to biomolecular adsorption, protein aggregation, and mouse red blood cell damage, although the implications for human health remain uncertain.

Aged aircraft exhaust poses a rising threat to human health

Fine particulate matter consists of tiny particles with diameters in the nanometer range. They are produced, for example, by fuel combustion, remain suspended in the air and can penetrate deep into the respiratory tract.

Understanding how neutrophil signaling pathways disrupt the human intestinal barrier

The intestinal mucosal barrier separates the host from the gut lumen and is essential for systemic homeostasis.

Common blood pressure drug boosts brown adipose tissue activity and metabolism

Scientists have discovered that the drug losartan, commonly prescribed for high blood pressure, boosts brown adipose tissue activity in mice, enhancing their metabolism.

Early vasopressin use does not improve septic shock survival

A new study from researchers at Intermountain Health in Salt Lake City found that starting an advanced medication earlier for critically ill patients with life-threatening septic shock does not improve their survival, shorten hospital stays, or improve their recovery compared with waiting until their condition potentially worsens.

New immune profiling tool identifies antibodies that trigger preterm births

A typical pregnancy lasts 40 weeks, but for about 1 in 10 pregnant women labor begins too soon. Premature or preterm birth is the leading cause of newborn deaths worldwide.
