Long-term, persistent weekly or more frequent cannabis smoking leaves a distinct and partially reversible epigenetic footprint on blood DNA. These methylation changes strongly overlap with those from tobacco and may serve as biomarkers of smoke exposure.

Researchers warn that accelerating human-driven loss of microbial diversity threatens both planetary and human health. The Microbiota Vault Initiative offers a global, equitable framework to safeguard critical microbiomes for future generations.

A mouse study shows that dietary oleic acid, a key Mediterranean diet component, protects against age-related bone and microbiome damage triggered by periodontal infection. In contrast, a Western-style palmitic acid diet worsens bone loss and destabilizes the gut microbiome.

Researchers found that older adults who received AS01-adjuvanted shingles or RSV vaccines had a significantly lower risk of developing dementia within 18 months compared to flu vaccine recipients. The protective effect is likely linked to the AS01 adjuvant itself, highlighting new avenues for dementia prevention.

A new study published in Nutrients offers new insight into omega-6 and whether it is truly the proinflammatory fatty acid many claim it to be.

A new study by the Genomics and Microbial Evolution Group at the Miguel Hernández University of Elche (UMH) together with the Department of Host-Microbe Interactions at St. Jude Children's Research Hospital in Memphis, USA, sheds light on one of the great enigmas of microbiology: why only certain strains of common bacteria become pandemic pathogens.

A new study presented today at the 41st Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE) reveals that women with polycystic ovary syndrome (PCOS) have distinct gut microbiota and metabolic signatures linked to premature endometrial aging and a higher risk of adverse pregnancy outcomes.

Florida Atlantic University researchers have secured two key grants to investigate targeting a gene for the first time as a new approach to treat glioblastoma, a very aggressive and fast-growing type of brain cancer.

New research from the University of Pittsburgh School of Medicine and La Jolla Institute for Immunology, published today in Nature Microbiology, reveals an opportunity for developing a therapy against cytomegalovirus (CMV), the leading infectious cause of birth defects in the United States.

Even small drops in national income can significantly increase the risk of various forms of childhood malnutrition- not only undernutrition but also overweight and obesity, shows a study led by the Barcelona Institute for Global Health (ISGlobal), an institution supported by "la Caixa" Foundation.

Hansen's Disease, more commonly known as leprosy, is a chronic disease that can lead to physical impairment. Today it exists in over 100 countries, and while the infection is treatable, access to treatment varies widely with socioeconomic conditions.

A new study by the University of Vienna shows that particularly long periods of parental leave around the birth of a child are associated with a higher risk of unhealthy behavior - specifically smoking - in the long term.

A pioneering study has provided unprecedented insights into the immune response following pig-to-human kidney xenotransplantation.

Spinal cord injuries are currently incurable with devastating effects on people's lives, but now a trial at Waipapa Taumata Rau, University of Auckland offers hope for an effective treatment.

Mayo Clinic researchers have developed a new artificial intelligence (AI) tool that helps clinicians identify brain activity patterns linked to nine types of dementia, including Alzheimer's disease, using a single, widely available scan - a transformative advance in early, accurate diagnosis.

A new study in PLOS Biology shows that deep N2 sleep, rather than light N1 sleep, dramatically boosts the likelihood of “aha” moments in a challenging perceptual task. The researchers also reveal that aperiodic brain activity during sleep best predicts who will gain insight after a nap.

Citrate is essential for the metabolism and development of neurons. A membrane transport protein called SLC13A5 plays a central role in this process and has previously been linked to a particularly severe form of epileptic encephalopathy.

A major umbrella review shows that higher intake of vegetables and dairy products is linked to a lower risk of endometriosis, while butter and high caffeine intake appear to increase risk. However, the evidence remains weak due to limitations in existing observational studies.

Ribosomes are tiny molecular machines inside all living cells that build proteins, and ribosome biogenesis is the complex, multi-step process by which they are made.

Gene therapy for sickle cell disease may help improve a major contributing factor to stroke risk in patients, reports a new study from St. Jude Children's Research Hospital.
