New study uncovers why dispersed glioblastoma cells are more dangerous

A new study, led by researchers at Sylvester Comprehensive Cancer Center part of the University of Miami Miller School of Medicine, captured details of glioblastoma that had never before been seen and revealed a surprise finding: Glioblastoma cells that "cluster" together with other cells of the same type are less deadly than those that disperse from these clusters.

International societies release new guideline for 18F-flurpiridaz PET myocardial perfusion imaging

The Society of Nuclear Medicine and Molecular Imaging (SNMMI), American Society of Nuclear Cardiology (ASNC), European Association of Nuclear Medicine (EANM), and American College of Nuclear Medicine (ACNM) have issued a new clinical guideline for 18F-flurpiridaz PET myocardial perfusion imaging (MPI) and blood flow quantitation.

Study identifies microstructural brain changes from heading in amateur soccer athletes

A brain imaging technique developed by Columbia researchers has identified areas in the brain's cerebral cortex-just behind the forehead-that are most damaged by the repetitive impacts from heading a soccer ball.

Light-activated coating kills bacteria and viruses

Light on – bacteria dead. Disinfecting surfaces could be as simple as that. To turn this idea into a weapon against antibiotic-resistant germs, Empa researchers are developing a coating whose germicidal effect can be activated by infrared light.

Vitamin D2 supplementation linked to decrease in natural vitamin D3 concentration

Taking vitamin D2 might lower the body's levels of the more efficient form of vitamin D, vitamin D3, according to new research from the University of Surrey, John Innes Centre and Quadram Institute Bioscience.

New study reveals a 25-year rise in alcohol-induced mortality

In an analysis by race, sex, age, and geography, alcohol-induced death rates in 2024 are nearly double those in 1999, with a sharp increase at the onset of the COVID-19 pandemic.

Researchers identify seizure-associated depolarization as cause of post-ictal symptoms

People with temporal lobe epilepsy in particular often wander around aimlessly and unconsciously after a seizure. Researchers at the University Hospital Bonn (UKB), the University of Bonn, and the German Center for Neurodegenerative Diseases (DZNE) have identified a neurobiological mechanism that could be responsible for this so-called post-ictal wandering and potentially other postictal symptoms.

Tracking antibodies reveals four distinct COVID-19 vaccine responses

Two healthcare workers get COVID-19 vaccinations on the same day. Both show strong antibody responses initially, but six months later one stays healthy while the other contracts the virus. A new study published in Science Translational Medicine could help explain this difference.

Resistance training may help preserve aging nerves

Simple resistance training may help counteract age-related nerve deterioration that puts seniors at risk of injuries from falls and other accidents, according to cross-institutional research led by Syracuse University postdoctoral researcher JoCarol Shields and Department of Exercise Science Professor Jason DeFreitas.

Frequent soccer heading linked to alterations within the folds of the brain

In amateur soccer players, more frequent heading, or using the head to control or pass the ball, is linked to alterations within the folds of the brain, according to a study published on September 17, 2025, in Neurology, the medical journal of the American Academy of Neurology.

Holder vs Retort: How milk pasteurization shapes preterm infants’ gut health

Researchers at Vanderbilt University Medical Center found that pasteurization methods shape the gut microbiomes of preterm infants fed donor human milk. Holder pasteurization preserved microbial diversity and beneficial taxa better than Retort, producing microbiomes more similar to those from mothers’ own milk.

Fire-driven air pollution is rising worldwide and reversing decades of clean air gains

Global exposure to fire-related fine particulate matter (PM2.5) has increased sharply from 1990 to 2018, despite a decline in overall PM2.5 pollution. This surge has driven tens of thousands of additional deaths annually, especially in Eastern Europe and sub-Saharan Africa.

Long COVID linked to heavier periods and symptom flare-ups during menstruation

Researchers found that long COVID is linked to heavier, longer, and more irregular bleeding without disrupting ovulation. Symptom severity also peaks around menstruation, likely driven by hormonal and immune changes.

Loss of key Y chromosome gene causes infertility in male mice

In a new study conducted at the University of Hawaiʻi at Mānoa, researchers from the John A. Burns School of Medicine (JABSOM) have shown that the loss of a key male fertility gene leads to infertility and changes expression of hundreds of other important genes.
