Belgian scientists have uncovered new details about how the immune system responds to vaccines. Dendritic cells, which are key immune messengers that help kick-start the body's defenses, show specific responses to lipid nanoparticles.

Psychotherapy leads to measurable changes in brain structure. Researchers at Martin Luther University Halle-Wittenberg (MLU) and the University of Münster have demonstrated this for the first time in a study in "Translational Psychiatry" by using cognitive behavioral therapy.

GLP-1 receptor agonists are transforming obesity and diabetes care, but may reduce skeletal muscle mass, raising concerns about sarcopenic obesity. This comprehensive review explores the mechanisms, clinical implications, and mitigation strategies, including exercise, protein intake, and adjunct therapies.

Nearly 1 in 5 packaged foods sold in the US in 2020 contained synthetic dyes; products with these dyes had 141% more sugar and were disproportionately marketed to children. The study also revealed wide variability in dye use across companies, highlighting opportunities for reformulation.

Does insurance play a role in which critically ill patients live or die? The unfortunate answer may be yes, due in part to a difference in the rate of inter-hospital transfer, according to new research from the University of Michigan.

Regular yogurt consumption is linked with a lower risk of type 2 diabetes, according to credible but limited scientific evidence. The FDA has approved a qualified health claim in 2024, marking yogurt as a promising food-based tool for public health.

Researchers linked genetics, plasma metabolites, and Mediterranean diet adherence to dementia risk in two large US cohorts, showing APOE4 homozygotes had distinct metabolic pathways. Diet-related metabolites mediated protection, highlighting precision-prevention opportunities.

People with lower interleukin-6 activity have a reduced risk of cardiovascular diseases, a new LMU study reveals.

A new research paper was published in Volume 17, Issue 7 of Aging (Aging-US) on July 21, 2025, titled "Association of DNA methylation age acceleration with digital clock drawing test performance: the Framingham Heart Study."

UCLA scientists have developed the first comprehensive road map showing how the ovarian reserve forms in primates, providing crucial insights into women's health that could revolutionize treatments for infertility and hormonal disorders such as polycystic ovary syndrome, or PCOS.

Most research suggests that opioid overdoses involving multiple substances in the United States typically occur among people ages 25-54.

In a groundbreaking study, research scientists from the Indiana University School of Medicine and Regenstrief Institute found that individuals with a parent who died from liver disease face more than double the risk of developing alcohol-associated hepatitis, one of the deadliest forms of alcohol-related liver disease, compared with similar heavy drinkers without that family history.

A special set of neurons directs mice's attention to or away from their peers, depending on the situation. The Kobe University discovery has implications for finding causes for neuropsychiatric conditions such as autism spectrum disorder or schizophrenia.

Older adults who are overweight may face a lower risk of death in the first 30 days following major elective surgery compared with those who have a normal body mass index (BMI), new research suggests.

An analysis using data from the National Health and Nutrition Examination Survey (NHANES) among 5,374 women of reproductive age indicates that two thirds of women within this demographic have at least one modifiable risk factor, such as low folate status or unmanaged diabetes, that can increase the chance of serious birth defects.

In a revealing Genomic Press Interview published today in Brain Medicine, Professor Alexei Verkhratsky dismantles decades of neuroscience orthodoxy with discoveries that position neuroglia as active architects of brain function rather than passive cellular bystanders.

A natural compound could help fight aggressive leukaemia and amplify the effect of chemotherapy drugs.

Researchers have developed a new light technology that appears to improve cognitive function in Alzheimer's patients in clinical trials.
