Two emerging pathogens with animal origins - influenza D virus and canine coronavirus - have so far been quietly flying under the radar, but researchers warn conditions are ripe for the viruses to spread more widely among humans.

Researchers at UC San Francisco have uncovered a new clue to how Epstein-Barr virus (EBV) could contribute to multiple sclerosis (MS), a chronic autoimmune disease that affects nearly one million Americans.

A research team from POSTECH and ImmunoBiome in Korea, led by Professor Sin-Hyeog Im, has uncovered a new mechanism showing how butyrate-a short-chain fatty acid produced by gut commensal bacteria-enhances T follicular helper (Tfh) cell activity to promote antibody production and strengthen mucosal vaccine efficacy.

Announcing a new article publication for BIO Integration journal. Extracellular vesicles (EVs) are membrane-bound nanoparticles secreted by cells and have emerged as promising therapeutic agents for osteoarthritis (OA).

Antioxidants have been marketed as miracle supplements, touted for preventing chronic diseases and cancers; treating COPD and dementia; and slowing aging.

Improving blood flow to the brain by opening a narrowed neck artery may not improve patients' cognitive skills, according to a preliminary late-breaking science presentation at the American Stroke Association's International Stroke Conference 2026.

A large U.S. firefighter cohort study identified personal, occupational, and department-level predictors of serum PFAS concentrations, highlighting both modifiable exposures and persistent background sources. Some protective practices, blood or plasma donation, and drinking water sources were associated with differences in specific PFAS analytes, although causal relationships require further longitudinal study.

Giving the clot-busting medication alteplase at the site of a blocked brain artery after blood clot removal may increase the number of patients who fully recover, according to preliminary late-breaking science presented at the American Stroke Association's International Stroke Conference 2026.

Researchers at Baylor College of Medicine report in Science Advances a breakthrough in human norovirus (HuNoV) research.

A new study, jointly led by Liverpool School of Tropical Medicine and the Centre for Research in Infectious Diseases (CRID) in Cameroon, has detected a DNA marker in a gene encoding for a key enzyme, known as cytochrome P450, that helps mosquitoes to break down and survive exposure to pyrethroids, the main insecticides used for treating bed nets.

COVID-19 vaccination is not the cause behind a decrease in childbirth, according to a study from Linköping University, Sweden.

A five-year image-based study in people with type 2 diabetes found metformin use was associated with lower odds of developing intermediate age-related macular degeneration. The observational findings suggest a potential protective link but do not establish causation and warrant prospective clinical trials.

Researchers from The University of Texas at Dallas and their international colleagues have determined the molecular signature of human sleeping -­ or silent -­ nociceptors: sensory neurons that are unresponsive to touch or pressure yet are key culprits in neuropathic pain.

Following a Mediterranean diet is associated with a lower risk of all types of stroke among women, according to a study published on February 4, 2026, in Neurology Open Access, an official journal of the American Academy of Neurology.

How to reduce suffering in children with advanced cancer remains an ongoing but urgent question. A Mass General Brigham-led study examined whether systematically surveying children with advanced cancer and their parents about their symptoms and quality of life, providing feedback to children, families, and clinicians-and acting on that information by implementing personalized palliative care-could improve patients' experiences.

Cancer cells carry thousands of mutations, but not all mutations are created equal. Some make tumors highly visible to the immune system, while others help cancers hide.

Autism has long been viewed as a condition that predominantly affects male individuals, but a study from Sweden published by The BMJ shows that autism may actually occur at comparable rates among male and female individuals.

Testing menstrual blood for human papillomavirus (HPV) could be a "robust alternative or replacement" for current cervical cancer screening by a clinician, finds a study from China published by The BMJ today.

Recent research at Åbo Akademi University highlights that promoting thriving is essential for older persons in care homes and constitutes a cornerstone of high-quality aged care.

Researchers from the Centre for Addiction and Mental Health (CAMH) and the Institute of Neurophysiology at Uniklinik RWTH Aachen in Germany have deciphered the molecular signature of so-called sleeping nociceptors-a type of pain-sensing nerve cell that normally remains quiet and does not respond to touch or pressure, but can become overactive and drive chronic pain.
