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 […]

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 […]

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 […]

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 […]

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 […]

Study shows novel test can detect new and recurrent bladder cancer

A revolutionary new urine screening test that utilizes a novel Keratin 17 (K17) cancer biomarker can detect the presence of new bladder cancer in patients with hematuria, or blood in the urine, according to a study led by researchers at Yale Cancer Center, Stony Brook University, and KDx Diagnostics, Inc. The findings also […]

“Electronic Nose” Accurately Sniffs Out Hard-to-Detect Cancers

An odor-based test that sniffs out vapors emanating from blood samples was able to distinguish between benign and pancreatic and ovarian cancer cells with up to 95 percent accuracy, according to a new study from researchers at the University of Pennsylvania and Penn’s Perelman School of Medicine. The findings suggest that the Penn-developed […]

Healing hydrogels

Hydrogels are polymer materials made mostly from water. They can be used in a wide range of medical and other applications. However, previous incarnations of the materials suffered from repeated mechanical stress and would easily become deformed. A novel crystal that can reversibly form and deform, allows hydrogels to rapidly […]

Tiny implant cures diabetes in mice without triggering immune response

A team of researchers led by diabetes specialists and biomedical engineers at Washington University School of Medicine in St. Louis and Cornell University has demonstrated that using a miniscule device, they can implant insulin-secreting cells into diabetic mice. Once implanted, the cells secrete insulin in response to blood sugar, reversing […]

A connectomic study of a petascale fragment of human cerebral cortex

The human brain is the most interesting object in neuroscience. Recently, researchers from Harvard University and Google released a 1.4-petabyte dataset of a small sample of the human cerebral cortex (a surface layer of the brain, responsible for higher-level cognitive functions). The sample has been imaged at 4nm-resolution using electron […]

Case Western Reserve-led research team aims to determine which diabetic individuals can successfully donate corneas for transplant (and which should not)

About a third of the corneal transplant surgeries in the United States involve people with diabetes who donate their corneas after death. The number of corneal transplants has grown over the last decade, but through continuous research, the medical community has learned that not all corneal tissue from diabetics may […]
