The communication network in the developing brain builds when neurons partner up to form contact points called synapses, allowing signals to pass form one cell to another.

Cognitive decline in Alzheimer's disease differs substantially from one person to the next and is not well predicted by existing medical tests.

A national study of 5,436 Chinese youths found that longer breastfeeding was not linked to cognition before adjustment, but was associated with modestly better math and word-recognition scores after socioeconomic factors were considered. The findings suggest that family socioeconomic patterns can mask breastfeeding-cognition associations, especially in settings where longer breastfeeding is more common among lower-SES households.

Long-acting RNA interference therapy for hypertension could shift blood pressure control from daily pill-taking to scheduled, system-led protection. But the authors warn that this “vaccine-like” model must preserve lifestyle support, monitoring, and follow-up to avoid clinical disengagement.

GLP-1-based therapies helped adults with overweight or obesity lose weight mainly by reducing fat mass and visceral adipose tissue, while lean body mass losses were generally modest. The findings suggest these treatments can support higher-quality weight loss when paired with individualized care, nutrition, and resistance training.

During infection, pathogens must adapt quickly to the conditions to thrive inside the body. A research team at the University of Basel, Switzerland, has uncovered how a key protein switches on the machinery that enables Leptospira pathogens to survive and cause disease.

Older adults recovering from serious blood clots often face long periods of hospitalization or rehabilitation due to a higher rate of recurrence.

Uterine fibroids may be less common in Latina women than earlier estimates suggested, according to new research.

University of Houston biologists have contributed to a potential breakthrough in treating Crohn's disease by shifting the clinical focus from symptom management to addressing a primary underlying cause of the condition.

A new study from the University of Victoria (UVic) has identified a segment of traumatic brain injury survivors who are using psychedelics to self-medicate for cognitive, mood and somatic symptoms such as headaches.

Rural youth experience higher rates of firearm exposure, handgun carrying and associated mental health risks, according to Rutgers researchers.

Early exposure to PFAS, a group of widely used compounds known as "forever chemicals," was associated with a higher risk of acute lymphoblastic leukemia, the most common childhood cancer, according to University of California, Irvine Joe C. Wen School of Population & Public Health researchers.

People with advanced heart, kidney and metabolic disease may face a higher risk of developing cancer, according to new research published today in the American Heart Association's peer-reviewed scientific journal Circulation: Population Health and Outcomes.

Researchers at VIB and VUB have developed a powerful new way to study how the immune system behaves inside lung tumors.

Vision Zero begins with a simple but powerful premise: No loss of life on the transportation system is acceptable. Despite the ambitious nature of this goal, the United States has made little meaningful progress toward its realization.

Virginia Tech scientists at the Fralin Biomedical Research Institute say the increased risk of cardiovascular disease after menopause may stem not only from declining hormone levels, but also from how those changes influence gene activity.

Researchers at University of California San Diego School of Medicine, the Salk Institute and Sanford Burnham Prebys have received a four-year, $13 million award from the California Institute for Regenerative Medicine (CIRM) to investigate how to reverse age-related neurodegeneration by eliminating what the researchers call "RNA pollution" in aging neurons.

Colorectal cancer (CRC) is the second most common cause of cancer death in the United States and disproportionally impacts people who receive care in under-resourced settings.

Understanding how wounds heal after injury could be a step closer thanks to a new mathematical model developed by researchers at the University of Bristol.

Cedars-Sinai Health Sciences University investigators have developed and successfully tested a new treatment for pregnant women with severe early preeclampsia, a leading cause of premature birth as well as maternal and fetal death.
