Age, genetics and lifestyle are known to influence how people respond to viral infections. Scientists also know that differences in immune response play an important role, but exactly how these factors shape the course of an infection has remained unclear.

A new, large-scale Curtin University study has found children who experience parental loss are twice as likely to develop a mental health disorder, compared to those living with both parents.

In a rare pair of papers published back-to-back in the journal Genes & Development, research teams led by senior author Anindya Bagchi, PhD, associate professor in the Cancer Genome and Epigenetics Program at Sanford Burnham Prebys Medical Discovery Institute, establish a unified framework that governs one of cancer's most powerful master regulators.

As the government prepares to introduce updated school food standards, an investigation by The BMJ finds that more than a third of the firms exhibiting at the UK's biggest school food show sell products high in fat, sugar or salt (HFSS).

Giving intravenous iron to patients with anemia before heart surgery reduces the need for a red blood transfusion and results in an extra day at home in the first 90 days after surgery, finds a clinical trial published by The BMJ today.

Machine learning-derived cellular aging clocks mapped more than 7,000 plasma proteins to over 40 cell types, revealing marked differences in how individual cell populations age. These blood-based signatures were associated with future risks of Alzheimer’s disease, ALS, lung cancer, type 2 diabetes, and mortality across follow-up extending to 15 years.

A review published today in Nature Reviews Cardiology provides the most detailed picture yet of how nicotine damages the cardiovascular system – tracing the biological chain of events from the moment nicotine binds to receptors in blood vessel walls through to the atherosclerotic plaque rupture that triggers heart attacks and strokes.

A nearly $1 million grant from the National Science Foundation will allow University of Houston researchers to investigate how mutation rates evolve across species - work that could offer critical insights into cancer progression and antibiotic resistance.

Scripps Research assistant professor Tiantian Liu has received a five-year NIAID DP2 award from the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health (NIH), to advance basic understanding of immune processes that could aid the design of next-generation immunotherapies.

People living near dry cleaners may have a higher risk of developing Parkinson's disease according to a new nationwide study led by researchers at Barrow Neurological Institute in Phoenix.

Use of the antiseizure drug valproate by fathers before conception is not associated with neurodevelopmental disorders like autism or attention-deficit/hyperactivity disorder (ADHD) in their children, according to a new study published August 19, 2026, in Neurology®, an official journal of the American Academy of Neurology.

Researchers at The University of Texas MD Anderson Cancer Center found that, in preclinical models of colorectal cancer, tumors can start damaging peripheral nerves before chemotherapy begins.

A urinary tract infection that follows a moderate brain injury can worsen cognitive problems caused by the injury, new research in mice shows.

A compound produced in the body after eating pomegranates improves heart function by up to 80% in a type of heart failure with limited treatment options.

A nationally representative US study found that 68.6% of adults with access to medical records viewed immediately released test results before hearing from a healthcare practitioner. Among these viewers, only 34.9% rated their understanding as very good, with comprehension varying by region, digital literacy, patient-centered communication, and experiences of medical care discrimination.

A large prospective U.S. study followed more than 111,000 adults to examine whether sugar-sweetened and artificially sweetened beverage intake was associated with gastric cancer incidence. Researchers identified 278 gastric cancer cases over 3.2 million person-years and found that associations differed according to beverage type and level of consumption.

A 19-year German claims analysis of more than 2.8 million pregnancies found that recorded maternal vaccination increased substantially after national recommendations for influenza and pertussis immunization were introduced. Influenza vaccination reached 19.4% and pertussis vaccination about 37% in 2020-2022, while COVID-19 vaccination was not captured in the databas

Analysis of 7,392 menu items from 200 large restaurant chains found that lower-calorie options on two major UK food delivery platforms carried a substantially higher cost per 100 kcal than higher-calorie items. The findings suggest that per-calorie pricing may create financial disincentives for choosing lower-calorie foods, with potential implications for diet-related health inequalities.

Cancer epidemiology is not merely about counting cases; it is a dynamic field that informs screening policies, resource allocation, and clinical trial design.

Brands that market hemp-derived, intoxicating cannabinoid products are capitalizing on lack of oversight on social media platforms to reach consumers, according to Rutgers Health researchers.
