New genetic test speeds up brain tumor diagnosis to just two hours

Scientists and medics have developed an ultra-rapid method of genetically diagnosing brain tumors that will cut the time it takes to classify them from 6-8 weeks, to as little as two hours – which could improve care for thousands of patients each year in the UK.

Blood filtration may offer new hope for removing microplastics from the body

Researchers report the first evidence that therapeutic apheresis, a blood-filtration technique, can remove microplastic- and nanoplastic-like particles from humans with ME/CFS. While promising, further studies are needed to quantify removal and assess clinical benefits.

Maternal RSV vaccine and nirsevimab sharply cut infant hospitalizations, new data show

Widespread use of maternal RSV vaccination and nirsevimab during the 2024–2025 U.S. RSV season led to a significant reduction in RSV-associated hospitalizations among infants aged 0–7 months. The largest benefits were seen in the youngest and most vulnerable infants, particularly during peak winter months.

BMI changes in adolescence mediate the effect of air pollution on metabolic health

Changes in Body Mass Index (BMI) during adolescence play an important role in the association between air pollution exposure and insulin resistance, according to a new study led by investigators from the Keck School of Medicine of USC.

Longer breastfeeding boosts brain growth and thinking skills in teens, study shows

Longer breastfeeding duration is associated with greater cortical thickness, surface area, and improved fluid cognition in adolescents. These brain structures and cognitive benefits remain stable over two years and support current recommendations for extended breastfeeding.

Gut bacteria and genes jointly shape obesity risk, review reveals hidden links

Researchers examined the heritability of body mass index (BMI), highlighting that genetics and the gut microbiome both play major roles in obesity risk. The review emphasizes that maternal microbiome transmission and family environment may help explain “missing heritability” beyond known genetic factors.

Eating kombu daily enhances gut health and heart markers in men

A 12-week randomized trial found that daily intake of boiled kombu (Laminaria japonica) powder reduced body fat and raised adiponectin in Japanese men, while improving blood pressure and gut microbiota in both sexes. No significant effects were seen in women for body fat reduction or adiponectin.

NIH researchers develop poly-metabolite score to measure ultra-processed food intake

For the first time, researchers at the National Institutes of Health (NIH) identified patterns of metabolites in blood and urine that can be used as an objective measure of an individual's consumption of energy from ultra-processed foods.

Study reveals dual role of TEAD proteins in neural development

Scientists at St. Jude Children’s Research Hospital found that, in neural development, the same set of proteins involved in cellular self-renewal can also facilitate differentiation with the right binding partner.

Most Americans back MMR vaccine as measles surges and misconceptions rise

A national survey shows that most Americans still support MMR vaccination for children, but public understanding of measles complications and vaccine facts is declining. Despite a sharp rise in measles cases, misconceptions about vaccine risks and autism persist.

New discovery may help explain why some people infected with CHIKV develop severe joint pain

Chikungunya virus (CHIKV) is a mosquito-borne pathogen that has been identified in more than 110 countries around the world. The virus typically causes flu-like symptoms, but it can also trigger chronic, severe joint pain in some people.

Snooze alarms steal hours of sleep each month, new research shows

Researchers analyzed over 3 million sleep sessions from a global cohort of smartphone users and found that more than half used snooze alarms, with frequent snoozing linked to irregular sleep patterns. The study highlights potential health implications and the need for further research into the effects of repeated snooze use.

Personalized gene editing corrects fatal infant metabolic disorder in world-first treatment

Researchers have used a personalised base-editing gene therapy to successfully treat an infant with carbamoyl-phosphate synthetase 1 (CPS1) deficiency, a rare and life-threatening inborn error of metabolism. This pioneering approach chemically corrects the underlying mutation without cutting DNA, showing promise for precision treatment of ultrarare genetic disorders.

US withdrawal from global health bodies threatens millions with hunger and disease

A new Perspective in The American Journal of Clinical Nutrition warns of catastrophic global nutrition and health impacts if the US withdraws from the WHO and dismantles USAID. The authors urge urgent policy reversal and call for collaborative global action to prevent widespread humanitarian crises.

Air pollution fuels artery damage and accelerates heart disease, review finds

Researchers reviewed how air pollution, especially fine particulate matter (PM2.5), drives the development and worsening of atherosclerosis, a leading cause of heart attacks and strokes. Their findings highlight robust links between air pollution exposure, early artery changes, and underlying biological mechanisms fueling cardiovascular risk.
