Wildfire smoke can trigger breathing problems and flare-ups for people with chronic obstructive pulmonary disease (COPD), yet many people are not receiving the trusted health information they need to stay safe, according to a new study in the May 2026 issue of Chronic Obstructive Pulmonary Diseases: Journal of the COPD Foundation, a peer-reviewed, open access journal.

When semaglutide's popularity exploded following FDA approval for weight management in 2021, so too did a wave of calls to poison control centers.

Scientists from the Department of Microbiology of the University of Malaga, also members of the Institute of Subtropical and Mediterranean Horticulture 'La Mayora' (IHSM), have discovered a hitherto unknown mechanism that allows the bacterium Bacillus cereus, which is responsible for food poisoning and human infections, to protect itself against antibiotics and adverse conditions.

A protein that acts as a 'control switch,' preventing Mycobacterium tuberculosis from accessing the energy sources it needs to survive, has been identified by researchers at the University of Surrey.

The research group led by CIC biomaGUNE's Ikerbasque Research Professor Aitziber L. Cortajarena has developed an innovative anti-fibrotic and anti-tumor treatment by binding a synthetic protein to gold nanoclusters (small aggregates of approximately 6 atoms of gold).

Curtin University Curtin University researchers will examine the 'partygoing' behaviours of young people in regional areas, the use of nicotine pouches and ways to promote physical activity among young people as part of new projects funded by Healthway.

TRIMTECH Therapeutics, a biotechnology company developing novel small molecule therapies that target and degrade protein aggregates associated with neurodegenerative diseases, today announced it has raised an additional $14 million in seed funding, bringing the total for the round to $47 million (£35 million).

Menstrual cycle phases influence heart autonomic regulation, showing HRV variations, yet muscle performance and mood states remain largely unchanged.

Higher serum 25-hydroxyvitamin D levels were independently associated with lower LDL-C, triglycerides, and lipoprotein(a) in 773 male professional athletes. The cross-sectional study cannot establish causality, but it suggests that vitamin D status may be linked to cardiovascular risk-related lipid markers, even in elite athletic populations.

A randomized, crossover trial in healthy adult men found that 4 weeks of L-tyrosine supplementation at doses up to 4 g/day did not cause clinically meaningful changes in safety markers, diet, blood pressure, or body measures. The highest tested dose, 4 g/day, was identified as the no-observed-adverse-effect level under the study’s four-week conditions, although broader and longer-term studies are still needed.

Researchers reviewed Ebola disease cases outside Africa from 1976 to May 2026 and found only 28 confirmed epidemic-linked cases, most involving medical evacuation or occupational exposure. Only four latent travelers were diagnosed after border screening, suggesting that undetected intercontinental spread remains rare when outbreaks are controlled at source.

A Eurosurveillance report describes a multi-country response to an Andes virus outbreak linked to the Dutch-flagged expedition cruise ship MV Hondius, with 13 cases and three deaths reported as of June 18, 2026. Investigators found evidence consistent with an initial zoonotic infection before embarkation, followed by likely person-to-person transmission among passengers and crew in a confined ship setting.

Cancer is often considered a disease of aging. Older adults are at higher risk because they have had more time to accumulate cellular damage that can trigger tumor formation.

Pregnant women with a severe form of nausea face increased risks for several pregnancy and birth complications, according to a new Stanford Medicine study of 2.5 million California births.

Blocking IL1RAP, a receptor that sits at a key control point in inflammatory signaling, can disrupt the tumor-driven inflammatory network that helps pancreatic cancer resist treatment, according to new research.

In 822 deceased older adults from ROS and MAP, researchers linked stable psychological traits to multi-omic molecular subtypes of Alzheimer’s dementia using postmortem brain tissue from the dorsolateral prefrontal cortex. Neuroticism and loneliness were associated with molecular progression, while purpose in life showed subtype-specific inverse associations, suggesting psychological traits may align with Alzheimer’s biology beyond conventional neuropathology.

Researchers found that malaria-Chagas and dengue-ATL hotspots in the Brazilian Amazon aligned with distinct agrarian, socioeconomic, and environmental landscapes. The findings suggest that disease surveillance should account for land use, poverty, forest structure, mining, and local livelihoods rather than treating each infection in isolation.

An experimental study in Science Advances shows that statins, primarily fluvastatin in these experiments, may promote low-level muscle myopathy by reducing isoprenoid-dependent protein prenylation rather than by cholesterol lowering. In primed muscle cells and mouse models, impaired YAP signaling, reduced glycolysis, NLRP3/caspase-1 activation, and nuclear FOXO accumulation increased atrogin-1, reduced protein synthesis, and weakened muscle function.

Researchers mapped 442,239 single nuclei from nonfailing human hearts to chart how cardiac cells change from fetal development to older adulthood. The study identified PRDM16 as an age-declining cardiomyocyte regulator, with experimental evidence showing that restoring Prdm16 in aged mouse hearts improved systolic function and partly reversed aging-associated transcriptional patterns.
