Common medications trigger potentially harmful prescribing cascades in older adults

A new Ontario-wide study reveals that common medications, from statins to iron supplements, are quietly setting off prescribing cascades that leave older adults unknowingly taking drugs to treat side effects of other drugs.

Childhood chemotherapy leaves lasting DNA damage in healthy cells

Chemotherapy, which saves the lives of many children with cancer, causes previously unknown DNA alterations in the liver and leaves genetic footprints in other healthy cells as well.

Laser therapy offers new hope for inoperable pancreatic tumors

UCI Health, the clinical enterprise of the University of California, Irvine, is conducting a first-in-human, phase 1 clinical trial using laser light to target localized but inoperable pancreatic tumors to help patients become cancer free.

Refined starch activates immune pathways after low-carb weight loss

After substantial weight loss on a very-low-carbohydrate diet, participants who switched to a diet rich in refined starch showed greater activation of circulating immune and metabolic pathways than those who continued the low-carbohydrate diet or consumed a high-carbohydrate diet rich in added sugar. Mouse experiments suggested that activation of the complement immune pathway may help explain the inflammatory response associated with starch intake.

Strength training shows no added arrhythmia risk in people with arrhythmogenic cardiomyopathy

People living with arrhythmogenic cardiomyopathy (ACM), a heritable heart condition that can significantly increase risks for sudden cardiac death, are advised to avoid high-intensity aerobic exercise.

Study reveals hidden DNA damage from childhood chemotherapy

The amount of DNA damage caused by certain chemotherapies used to effectively treat childhood cancer has been revealed, along with a hidden impact on the liver, paving the way for future research into new ways to mitigate these impacts.

Aging brain actively shapes biology and progression of tumors

Brain tumors develop within an organ that changes substantially with age. A new review in Ageing and Cancer Research & Treatment examines evidence that the aging brain microenvironment may influence brain tumor progression, treatment resistance, and cognitive outcomes.

Rituximab alters T-cell metabolism in patients with nephrotic syndrome

Nephrotic syndrome is caused when the filtering system in the kidneys is damaged, allowing large amounts of protein to leak into the urine.

Popular AMH blood test fails to predict natural fertility

Increasing numbers of Australian women are using a blood test to assess their fertility, but new research suggests it may not provide the answers many are looking for.

Symptomless liver condition linked to heart and kidney disease

A common liver condition thought to be harmless could be dramatically increasing the risk of heart disease, kidney failure and premature death, according to a new review led by University of Manchester and Northern Care Alliance NHS Foundation Trust researchers.

Nighttime light exposure may alter heart structure and function

Exposure to light during the nighttime is linked to important and potentially harmful changes to the structure and function of the heart, according to a study of more than 11,000 people published in the European Heart Journal today (Thursday).

Tizanidine looked promising early in a migraine trial, but the benefit did not last

A randomized, double-blind, placebo-controlled trial found that low-dose tizanidine did not provide sustained reductions in headache burden over 12 weeks in people with episodic migraine, despite a transient improvement with the 1 mg dose at week 4. Exploratory analyses suggested that smoking and sex may influence tizanidine exposure, while sex-specific efficacy signals remained hypothesis-generating and require confirmation.

Gut microbiome may reveal inflammation and future disease risk better than age

Gut microbiota composition explained more variation than chronological age in nearly all inflammatory cytokines and most physiological measures examined, with specific microbial profiles linked to markedly different patterns of inflammation across adulthood. People with the Bacteroides 2 enterotype showed an inflammaging-like profile decades earlier than other groups and had a higher risk of subsequent disease, while a high-diversity microbiota profile was associated with lower inflammation and reduced disease incidence.

Blood protein profiling could improve rare disease diagnosis

Researchers from Queen Mary University of London, the Berlin Institute of Health at Charité (BIH) and Genomics England have shown that measuring proteins in the blood can provide important additional clues about the effects of genetic variants, helping to identify diagnoses and potential new disease-causing genes that genome sequencing alone has been unable to resolve.

Spleen imaging features may reveal coronary artery disease risk

A new study led by investigators from Mass General Brigham reveals that certain features in the spleen hidden within imaging scans may signal a person's risk of coronary artery disease (CAD), suggesting targets for prevention and treatment.

Chaotic tumor environments may trigger cancer cell invasion

In 2024, malignant tumors caused more than 21,300 deaths in Austria, 4.7% more than in 2014. Faced with a similarly pressing global challenge, scientists are striving to better understand what drives cancer cells to grow, spread, and invade healthy tissue.

Pink noise boosts brain waste clearance during sleep

During the day, waste products such as lactic acid and worn-out proteins build up in the brain. When we sleep at night, waves of cerebrospinal fluid (CSF) help to wash away this waste, keeping the brain healthy.

Early B-cell therapy linked to better MS disease control

For people recently diagnosed with multiple sclerosis (MS), early treatment choices were associated with only slight differences after two years, based on the first treatment they used, according to a study published September 9, 2026, in Neurology Open Access, an official journal of the American Academy of Neurology.

New nanobody antivenom offers broad protection against Indian cobras

Snakebite is a neglected tropical disease, causing hundreds of thousands of deaths and disabilities each year. India alone reports nearly 50,000 deaths every year, the most by snakebite in the world.

Gut infection leaves long-lasting immune ‘memories’ at the brain’s borders in mice

In mice, intestinal infections reshaped dural CD4+ T-cell populations and seeded the brain’s outer meningeal border with antigen-specific memory cells that persisted for months and mounted rapid recall responses to bloodborne antigens. Oral priming was associated with reduced Salmonella spread to the brain and modest cross-protection in an engineered shared-antigen Candida model, although the researchers could not definitively prove that dural CD4+ T cells alone caused the protection.
