Colorized transmission electron micrograph of HIV-1 virus particles (yellow) budding and replicating from an H9 T cell (dark blue). The virus particles are in various stages of maturity, which accounts for differences in shape.

In 2023, approximately 11% of U.S. 12th graders reported using delta-8-THC, with higher usage in the South and Midwest and states lacking cannabis regulations. Credit: SciTechDaily.comUse of the psychoactive cannabis product is higher in states without existing delta-8 regulations or cannabis legalization, NIH-funded study finds.Approximately 11% of 12th-grade students across the United States reported past-year use of delta-8- tetrahydrocannabinol (delta-8-THC, or delta-8 for short), according to an analysis of data from…

NIH researchers conducted a detailed study on individuals experiencing anomalous health incidents, known as Havana Syndrome, and found no significant MRI-detected brain injuries or clinical differences compared to controls. Despite extensive testing, the symptoms, which include cognitive dysfunction and dizziness, were not linked to detectable neurological damage but were acknowledged as genuine and impactful. Compared to healthy volunteers, affected U.S. government personnel did not exhibit MRI-detectable brain injury or…

A comprehensive study supported by the National Institutes of Health demonstrates a significant link between frequent cannabis smoking and increased risks of heart attack and stroke. Credit: SciTechDaily.comNIH-funded observational study shows risk grows sharply with more frequent use.Frequent cannabis smoking may significantly increase a person’s risk for heart attack and stroke, according to an observational study supported by the National Institutes of Health. The study, published in the Journal of the American Heart…

A study by the National Institutes of Health found that adopting a vegan or ketogenic diet leads to significant immune system changes, with the vegan diet enhancing innate immunity and the keto diet boosting adaptive immunity. Both diets also caused metabolic changes and altered the gut microbiome.NIH study finds distinct immune responses occur quickly when diets change, more research needed to determine health effects.Researchers at the National Institutes of Health (NIH) observed rapid and distinct immune system changes…

Caloric restriction may promote muscle rejuvenation and essential health pathways, as supported by the CALERIE study. Reduced caloric intake benefits muscle strength and impacts genes similarly to animal models, notably boosting energy metabolism genes and reducing inflammation.NIH study suggests a small reduction in daily calories is beneficial for wellness.Reducing overall calorie intake may rejuvenate your muscles and activate biological pathways important for good health, according to researchers at the National…

Advances in Alzheimer’s research have introduced groundbreaking diagnostic methods and treatments aimed at slowing disease progression. Early detection through biomarkers and blood tests offers a new horizon for effective intervention and personalized care strategies.Groundbreaking progress in Alzheimer’s treatment and diagnostics, including biomarkers and blood tests, heralds a new era of early intervention and personalized care in dementia research.Until recently, a diagnosis of dementia might help explain cognitive…

Cognitive behavioral therapy effectively reduces anxiety symptoms and alters brain activity in children with anxiety disorders, offering insights for personalized treatment approaches. Credit: SciTechDaily.comNIH researchers found widespread differences in the brains of children with anxiety disorders that improved after treatment.Researchers at the National Institutes of Health have found overactivation in many brain regions, including the frontal and parietal lobes and the amygdala, in unmedicated children with anxiety…

Researchers improved existing polygenic risk scores using health records and ancestrally diverse genomic data. Credit: Darryl Leja, National Human Genome Research InstituteImproved genetic tests more accurately assess disease risk regardless of genetic ancestry.To prevent an emerging genomic technology from contributing to health disparities, a scientific team funded by the National Institutes of Health has devised new ways to improve a genetic testing method called a polygenic risk score. Since polygenic risk scores have…

Transmission electron micrograph of HIV-1 virus particles (red) budding and replicating from a segment of a chronically infected H9 cell (blue). Particles are in various stages of maturity; arc/semi-circles are immature particles that have started to form but are still part of the cell. Immature particles slowly change morphology into mature forms and exhibit the classic “conical or spherical-shaped core.” Image captured at the NIAID Integrated Research Facility (IRF) in Fort Detrick, Maryland.
