Protein in prostate cancer may inhibit tumor growth

Prostate cancer is the second most common cancer among men, according to the American Cancer Society. It’s also one of the trickiest cancers to diagnose and treat. But new research from the University of Georgia has identified a protein that appears to prevent cancer from spreading to and colonizing the bone, […]

A Breakthrough in the Physics of Blood Clotting

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 […]

Scientists reveal how brain cells in Alzheimer’s go awry, lose their identity

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 […]

In surprising twist, some Alzheimer’s plaques may be protective, not destructive

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 […]

To Prevent Delirium, Increase Mobility, Connection and Sleep

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 […]

How “good” viruses can selectively destroy DNA of “bad” bacteria

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. […]

New study showed that COVID-19 produces a strong autoimmune response

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 […]

Global travelers pick up numerous genes that promote microbial resistance

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 […]

Harnessing healthy behaviors to prevent dementia

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 […]

Study shows how taking short breaks may help our brains learn new skills

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 […]

Researchers Improve Efficiency and Accessibility of CRISPR

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 […]

Final results of SPRINT study confirm controlling blood-pressure is critically important in preventing heart disease and stroke

Follow-up data from the landmark SPRINT study of the effect of high blood pressure on cardiovascular disease have confirmed that aggressive blood-pressure management—lowering systolic blood pressure to less than 120 mm Hg—dramatically reduces the risk of heart disease, stroke and death from these diseases, as well as death from all […]

Scientists develop the ‘evotype’ to help unlock the power of evolution for better engineering biology

Scientists from the University of Bristol have pioneered a new approach to help biological engineers both harness and design the evolutionary potential of new biosystems. Their concept of the ‘evotype’ lays a foundation for the next generation of stable, safe and self-improving biotechnologies. A defining characteristic of all life is […]

Cancer a compelling reason to cut alcohol, and drink counting helps

A new study comparing different ways of encouraging people to reduce their alcohol intake has found telling people alcohol causes cancer makes them want to drink less, and encouraging them to count their drinks helps them do it. Lead author Professor Simone Pettigrew from The George Institute for Global Health said that […]

How Accurate Are Virtual Assessments of Cognitive Function?

Virtual care provided through telephone or videoconference has been broadly implemented in recent months because of the COVID-19 pandemic. A new analysis of published studies has examined the accuracy and reliability of virtual compared with in-person cognitive assessments for diagnosing dementia or mild cognitive impairment. The analysis, which is published […]

Lung cancer’s resistance to chemotherapy reveals new treatment approach

New research at the Garvan Institute of Medical Research and ANZAC Research Institute has uncovered a mechanism that helps lung cancer cells resist standard chemotherapies. A team led by Associate Professor David Croucher and Associate Professor Andrew Burgess found that individual lung adenocarcinoma cells, the most common form of lung […]

New method of gene analysis prevents early death in familial hypercholesterolemia

Researchers at Karolinska Institutet have investigated how a newly developed algorithm in connection with gene analysis can be used to improve the possibilities of preventing premature vascular disease and death in individuals with the hereditary lipid disorder, familial hypercholesterolemia. The findings, published in the Journal of Internal Medicine, show how […]

Studies reveal skull as unexpected source of brain immunity

The immune system is the brain’s best frenemy. It protects the brain from infection and helps injured tissues heal, but it also causes autoimmune diseases and creates inflammation that drives neurodegeneration. Two new studies in mice suggest that the double-edged nature of the relationship between the immune system and the […]
