Just as a computer's operating system can be rewritten after a major update, dengue infection can 're-programme' the body's immune system, leaving a long-lasting genetic imprint that influences how people respond to future infections-an effect not seen with vaccination.

An international team of scientists has revealed how rogue rings of DNA that float outside of our chromosomes – known as extrachromosomal DNA, or ecDNA – can drive the growth of a large proportion of glioblastomas, the most common and aggressive adult brain cancer.

Bedfont® Scientific Limited, an innovative med-tech company with over 48 years of knowledge and expertise in the manufacture of medical breath analysis devices, are seeking new strategic distribution partners at this year's European Respiratory Society (ERS) Congress.

A recent study published in Engineering has shed new light on the potential therapeutic effects of berberine (BBR), a natural compound derived from traditional Chinese medicine, in treating diabetic encephalopathy (DE).

Black adolescents with mental distress are less likely to use mental health services than their White peers, and Black girls are the least likely to access care, according to new research published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.241733.

When it comes to their survival, cancer cells have a host of backup plans.

Scientists have discovered why older people are more likely to suffer severely from the flu, and can now use their findings to address this risk.

Exposure to high concentrations of air pollution may worsen Alzheimer's disease (AD) by accelerating the buildup of toxic proteins in the brain and speeding up cognitive decline.

Women taking popular weight-loss medications during their reproductive years may be unaware of associated risks to pregnancy and unborn babies, warn Flinders University researchers.

Adults using smartphones on the toilet spent significantly more time seated and had 46% higher odds of hemorrhoids on colonoscopy. The cross-sectional study suggests prolonged sitting, not straining, may be the key driver of hemorrhoid risk.

Researchers in Australia found that after mandatory folic acid fortification, gestational diabetes rates tripled, maternal folate levels rose sharply, and placental hormone profiles shifted. The study links folate excess to increased GDM risk, highlighting the need to re-evaluate supplementation policies.

A feasibility study in Germany found that concertgoers strongly supported medical detection dogs for COVID-19 screening, with confidence rising after real-world use. The findings suggest canine testing could complement PCR and antigen tests, especially in large gatherings and high-traffic environments.

Researchers reviewed 13 studies of human milk oligosaccharides (HMOs) through 24 months of breastfeeding, analyzing 4,786 samples. Six “core” HMOs remained dominant, with total concentrations plateauing after 12 months and evidence suggesting persistence into the second year.

A large UK-based retrospective cohort study found that initiating metformin within 90 days of COVID-19 diagnosis reduced the risk of Long COVID by 64% in overweight and obese adults. The findings suggest metformin may offer a low-cost preventive option pending confirmation from randomized trials.

This Food Science & Nutrition review highlights mushrooms as nutrient-rich functional foods packed with bioactive compounds that support human health. It explores their therapeutic, industrial, and environmental applications, from disease prevention and drug discovery to bioremediation and bioenergy.

People with operable diffuse pleural mesothelioma may benefit from immunotherapy before and after surgery, based on results of a clinical trial exploring the sequence of treatment and the role of surgery for this difficult to treat cancer.

New research indicates that many patients who undergo surgery with the intent to cure early-stage cancer continue or start opioid prescriptions in the year following surgery.

A multi-center, randomized phase III trial has found that a three-week hypofractionated radiotherapy (HypoRT) schedule with concurrent chemotherapy provides similar survival outcomes and reduced toxicity compared to the standard six-week conventional fractionated radiotherapy (ConvRT) schedule for patients with limited-stage small cell lung cancer (LS-SCLC).

In a landmark study of Hispanic and Latino adults, researchers at University of California San Diego School of Medicine have identified a link between self-reported cognitive decline and blood-based biomarkers, which could pave the way for a simple blood test to help diagnose Alzheimer's disease and related dementias.

Adding the novel medication baxdrostat to standard care may help manage high blood pressure and delay the progression of kidney disease in people with chronic kidney disease and uncontrolled high blood pressure , according to preliminary research presented at the American Heart Association's Hypertension Scientific Sessions 2025.
