National Institutes of Health scientists and their collaborators found that hepatitis B virus (HBV)-associated acute liver failure (ALF) — a rare condition that can turn fatal within days without liver transplantation — results from an uncommon encounter between a highly mutated HBV variant and an unusual immune response in the patient’s liver that is mainly … Read more
NIH-funded study suggests that bacteria may regulate neuronal circuits behind movement in flies. A new study puts a fresh spin on what it means to “go with your gut.” The findings, published in Nature, suggest that gut bacteria may control movement in fruit flies and identify the neurons involved in this response
Study links frequent red meat consumption to high levels of chemical associated with heart disease. Researchers have identified another reason to limit red meat consumption: high levels of a gut-generated chemical called trimethylamine N-oxide (TMAO), that also is linked to heart disease.
The study showed for every five years a woman’s biologic age was older than her chronologic or actual age, known as age acceleration, she had a 15 percent increase in her chance of developing breast cancer. The study was published online Feb. 22 in the Journal of the National Cancer Institute.
Analysis of genetic data from more than 94,000 individuals has revealed five new risk genes for Alzheimer’s disease, and confirmed 20 known others. An international team of researchers also reports for the first time that mutations in genes specific to tau, a hallmark protein of Alzheimer’s disease, may play an earlier role in the development … Read more

NIH-funded discovery uses common antifungal drug to improve lungs’ ability to fight infection. Researchers say a widely-used antifungal drug may hold promise for treating people with cystic fibrosis, a life-threatening genetic disorder that causes serious damage to the lungs. In studies using human cells and animals models, the researchers found that the medication, called amphotericin, … Read more
Catheter ablation, a common cardiovascular procedure, appears no more effective than drug therapies in preventing strokes, deaths, and other complications in patients with atrial fibrillation. However, patients who get the procedure experience much greater symptom relief and long-term improvements in the quality of life, including fewer recurrences of the condition and fewer hospitalizations, than those … Read more
NIH study suggests tiny electrical brain waves may be a hallmark of successful memory retrieval. NIH scientists showed how electrical brain waves, called ripples, may help us remember our past experiences. Courtesy of Zaghloul lab, NIH/NINDSA sound, a smell, a word can all flood our minds with memories of past experiences. In a study of … Read more
Light physical activity such as gardening, strolling through a park, and folding clothes might be enough to significantly lower the risk of cardiovascular disease among women 63 and older, a new study has found. This kind of activity, researchers said, appears to reduce the risk of cardiovascular disease events such as stroke or heart failure … Read more
National Institutes of Health scientists studying the progression of inherited and infectious eye diseases that can cause blindness have found that microglia, a type of nervous system cell suspected to cause retinal damage, surprisingly had no damaging role during prion disease in mice. In contrast, the study findings indicated that microglia might delay disease progression. … Read more
A new study led by scientists in the Center for Cancer Research (CCR) at the National Cancer Institute (NCI) sheds light on one way tumors may continue to grow despite the presence of cancer-killing immune cells. The findings, published March 29, 2019, in Science, suggest a way to enhance the effectiveness of immunotherapies for cancer … Read more
The drug colchicine, used to treat the arthritic condition gout, could potentially reduce complications accompanying metabolic syndrome, a combination of high blood pressure, high blood sugar and other conditions that increase the risk of heart disease and type 2 diabetes, according to researchers at the National Institutes of Health. Their study appears in Diabetes, Endocrinology, and Metabolism. Previous studies … Read more
NIH study suggests our brains may use short rest periods to strengthen memories. In a study of healthy volunteers, National Institutes of Health researchers found that our brains may solidify the memories of new skills we just practiced a few seconds earlier by taking a short rest. The results highlight the critically important role rest … Read more
A research team led by scientists from NIH’s National Institute of Allergy and Infectious Diseases (NIAID) has determined how several antibodies induced by Epstein-Barr virus (EBV), a herpesvirus that causes infectious mononucleosis and is associated with certain cancers, block infection of cells grown in the laboratory. They then used this information to develop novel vaccine … Read more
Two proteins that bind to stress hormones work together to maintain a healthy heart in mice, according to scientists at the National Institutes of Health and their collaborators. These proteins, stress hormone receptors known as the glucocorticoid receptor (GR) and mineralocorticoid receptor (MR), act in concert to help support heart health. When the signaling between … Read more
