A nationwide Australian pilot screened more than 10,000 adults aged 18–40 years for high-risk genetic variants linked to hereditary cancer and familial hypercholesterolaemia, identifying clinically actionable findings in about 2% of participants.

A randomized crossover feeding trial in adults aged 65 years or older found that plant-forward diets incorporating either minimally processed lean pork or lentils produced similar short-term improvements in cardiometabolic and neuroactive biomarkers. Both diets supported metabolic health and functional stability, with no overall adverse biomarker effects attributable to including minimally processed red meat within a Dietary Guidelines–aligned pattern.

Environmental change is reshaping food availability, nutrient quality, and health risks, exposing major gaps in how nutrition science addresses climate-related stressors. This perspective argues that dietary supplements may have a context-dependent role but require rigorous, interdisciplinary research before informing public health action.

This cross-sectional study of 191 adolescent girls found that ≥2 hours of organized recreational physical activity in the past week was associated with lower breast percent water content and reduced oxidative stress. These biomarkers are linked to breast cancer risk, although causality and long-term outcomes cannot be inferred.

A simple blood test can help detect cancer in patients with non-specific symptoms such as fatigue, pain or weight loss. This is according to a Swedish study from Karolinska Institutet, Danderyd Hospital and others, published in Nature Communications.

As people age, structural brain changes influence their ability to adapt to the environment. New from eNeuro, Tatiana Wolfe and colleagues at the University of Arkansas characterized changes in the brain across two periods of adulthood that may correspond to changes in adaptive behavior.

When a rhinovirus, the most frequent cause of the common cold, infects the lining of our nasal passages, our cells work together to fight the virus by triggering an arsenal of antiviral defenses.

Through a statewide partnership, hospitals in Michigan drastically increased the number of patients who receive follow up imaging after undergoing aortic aneurysm repair, according to a recent study.

A new study from the Hebrew University of Jerusalem examined how thought-patterns associated with unfairness, known as perceived injustice, shape people's psychological responses to trauma.

Excitement is building for FIFA World Cup soccer games in Toronto and Vancouver in June and July, yet Canada's overburdened health systems may buckle with any additional demand, cautions an editorial published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.252094.

Neurological disorders represent a mounting public health crisis in China, exacerbated by rapid population aging.

After increasing for more than 25 years, lung cancer death rates are finally levelling off among women in European Union (EU) countries apart from Spain, according to predictions of mortality rates from the disease for 2026.

Autistic and non-autistic people express emotions differently through their facial movements, according to a new study, which may help to explain why emotional expressions are sometimes misinterpreted between the two groups.

With another Congressional deadline looming this month for most telehealth coverage under Medicare, a new University of Michigan study adds more data to the debate.

A study of 227 individuals who experienced neuro cognitive difficulties post COVID-19 infection – such as headaches, vertigo, balance dysregulation, changes in taste/smell, and brain fog – displayed a significant increase in their blood plasma of a crucial protein called tau, which is found in nerves and especially in the brain.

The gene variant posing the greatest genetic risk of late-onset Alzheimer's disease (AD) is called APOE-ε4. A different variant of the same gene, APOE-ε2, is thought to confer protection against AD.

A review of 130 studies links PFAS exposure to gestational diabetes, highlighting the need for further research on diabetes outcomes and environmental factors.

New research co-led by Indiana University School of Medicine scientists has exposed a vulnerability in acute myeloid leukemia by identifying the blood cancer's reliance on a specific signaling pathway involved in the body's inflammation response.

Caregiving in the modern era is challenging for even the most prepared adults. So, what happens when this burden falls on children?

Researchers at Mass General Brigham and Karolinska Institutet have identified a new method to predict asthma exacerbations with a high degree of accuracy. The study is published in Nature Communications.
