Heart attacks and strokes – the leading causes of death in human beings – are fundamentally blood clots of the heart and brain. Better understanding how the blood-clotting process works and how to accelerate or slow down clotting, depending on the medical need, could save lives. New research by Georgia […]

New technique models brain cells in older patients more accurately than ever before. Despite the prevalence of Alzheimer’s, there are still no treatments, in part because it has been challenging to study how the disease develops. Now, scientists at the Salk Institute have uncovered new insights into what goes awry […]

Salk scientists find brain’s immune cells form some plaques as a defense in Alzheimer’s, suggesting a new therapeutic direction. One of the characteristic hallmarks of Alzheimer’s disease (AD) is the buildup of amyloid-beta plaques in the brain. Most therapies designed to treat AD target these plaques, but they’ve largely failed […]

Like thousands of other people you may be starting your day with a cup of coffee. Maybe you consume more caffeine as your day goes by. But did you ever think that it might be seriously bad for you? Scientists at UCL found that big doses of daily caffeine may […]

A new physiological measurement of heart function developed at UVA Health could improve survival for heart-failure patients by identifying high-risk patients who require tailored treatments, a study has found. The study is the first to show a survival benefit from wireless pressure-monitoring sensors implanted in the pulmonary arteries. Pulmonary artery […]

Accelerated cognitive decline in patients with and without existing dementia is one of the most disturbing outcomes of hospitalizations for older adults, affecting at least 2.6 million Americans every year. But the condition, known as delirium, is believed to be preventable in up to 40 percent of hospital-acquired cases, and […]

A new study from Tel Aviv University (TAU) revealed a mechanism through which “good” viruses can attack the genetic systems of “bad” bacteria, destroying them and blocking their reproduction. The researchers demonstrated that the “good” virus (bacteriophage) is able to block the replication mechanism of the bacteria’s DNA without damaging its own. […]

COVID-19 causes a big variety of different symptoms and some of them are quite difficult to explain. Now a new University of Birmingham-led study discovered that at least some of those symptoms are due to the body's immune response against its own tissues and organs. This is some important knowledge […]

Carried like stowaways in the guts of international travelers, new and potentially deadly strains of antimicrobial-resistant superbugs may be coming to a community near you, suggests new research from Washington University School of Medicine in St. Louis. “Even before the COVID-19 pandemic, we knew that international travel was contributing to […]

A new Alzheimer’s disease drug will hit the market soon, the first in nearly two decades. But some experts say the evidence for it isn’t terribly strong and worry that it may cost a lot. Still, the announcement of its approval by the U.S. Food and Drug Administration made headlines […]

In a study of healthy volunteers, National Institutes of Health researchers have mapped out the brain activity that flows when we learn a new skill, such as playing a new song on the piano, and discovered why taking short breaks from practice is a key to learning. The researchers found […]

One of the most powerful tools available to biologists these days is CRISPR-Cas9, a combination of specialized RNA and protein that acts as a molecular scalpel, allowing researchers to precisely slice and dice pieces of an organism's genetic code. But even though CRISPR-Cas9 technology has offered an unprecedented level of […]
