NIH study uncovers blood vessel damage and inflammation in COVID-19 patients’ brains but no infection

In an in-depth study of how COVID-19 affects a patient’s brain, National Institutes of Health researchers consistently spotted hallmarks of damage caused by thinning and leaky brain blood vessels in tissue samples from patients who died shortly after contracting the disease. In addition, they saw no signs of SARS-CoV-2 in […]

Microbiome study: Gum disease-causing bacteria borrow growth molecules from neighbors to thrive

The human body is filled with friendly bacteria. However, some of these microorganisms, such as Veillonella parvula, may be too nice. These peaceful bacteria engage in a one-sided relationship with pathogen Porphyromonas gingivalis, helping the germ multiply and cause gum disease, according to a new University at Buffalo-led study. The […]

Stopping RAS inhibitors tied to worse outcomes in patients with advanced chronic kidney disease

Small studies have suggested that a group of medications called RAS inhibitors may be harmful in persons with advanced chronic kidney disease, and physicians therefore often stop the treatment in such patients. Researchers at Karolinska Institutet now show that although stopping the treatment is linked to a lower risk of […]

Artificial intelligence may diagnose the leading cause of blindness much earlier

Artificial intelligence is able to analyze vast amounts of information very quickly and efficiently. And, therefore, unsurprisingly it is very useful in medicine. Scientists from UCL and the Western Eye Hospital have now developed a new eye test, which takes advantage of AI technology to predict wet age-related macular degeneration […]

Testosterone therapy may help preventing type 2 diabetes

Type 2 diabetes is oftentimes called a lifestyle disease, because it is associated with obesity, poor levels of physical activity and a terrible diet. It can be prevented through lifestyle changes, but what are other options? A team of scientists led by the University of Adelaide conducted a 2 year […]

Scientists discover how our brains track where we and others go

For the first time, scientists have recorded how our brains navigate physical space and keep track of others’ location. Researchers used a special backpack to wirelessly monitor the brain waves of epilepsy patients as each one walked around an empty room hunting for a hidden, two-foot spot. In an article […]

Scientists at TAU develop new gene therapy for deafness

A new study from Tel Aviv University (TAU) presents an innovative treatment for deafness, based on the delivery of genetic material into the cells of the inner ear. The genetic material “replaces” the genetic defect and enables the cells to continue functioning normally. The scientists were able to prevent the gradual deterioration […]

Decoding our immune response is nothing but a genetic ‘turn off’

How genes get ‘switched on’ has fascinated scientists for decades, but equally important questions about how they are ‘turned off’ have been largely overlooked. As the messengers carrying instructions from DNA for the creation of proteins, the formation and decay of cellular RNAs is critical to maintaining cell stability and […]
