Researchers at the University of Helsinki and the Beatson Institute for Cancer Research in Glasgow have discovered how mutated cells promote their chances to form cancer. Typically, the accumulation of harmful cells is prevented by active competition between multiple stem cells in intestinal glands, called crypts.

A new Cleveland Clinic-led study has identified mechanisms by which COVID-19 can lead to Alzheimer's disease-like dementia. The findings, published in Alzheimer's Research & Therapy, indicate an overlap between COVID-19 and brain changes common in Alzheimer's, and may help inform risk management and therapeutic strategies for COVID-19-associated cognitive impairment.

So-called "good fatty acids" are essential for human health and much sought after by those who try to eat healthily. Among the Omega-3 fatty acids, DHA or docosahexaenoic acid is crucial to brain function, vision and the regulation of inflammatory phenomena.

In addition to these virtues, DHA is also associated with a reduction in the incidence of cancer.

Metformin is a widely prescribed blood sugar-lowering drug. It is often used as an early therapy (in combination with diet and lifestyle changes) for type 2 diabetes, which afflicts more than 34 million Americans.

Metformin works by lowering glucose production in the liver, reducing blood sugar levels that, in turn, improve the body's response to insulin.

A new CDC study finds the mRNA COVID-19 vaccines authorized by the Food and Drug Administration (Pfizer-BioNTech and Moderna) reduce the risk of infection by 91 percent for fully vaccinated people. This adds to the growing body of real-world evidence of their effectiveness. Importantly, this study also is among the first to show that mRNA vaccination benefits people who get COVID-19 despite being fully vaccinated

New research identified a novel interaction between the SARS-CoV-2 spike protein and the galectin-3-binding protein (LGALS3BP) which could be a new therapeutic anti-viral target. The research also found the presence of detectable viral RNA in blood in COVID-19 patients is a strong predictor of mortality.

An experimental, lab-made antibody can completely prevent nonhuman primates from being infected with the monkey form of HIV, new research published in Nature Communications shows.

The results will inform a future human clinical trial evaluating leronlimab as a potential pre-exposure prophylaxis, or PrEP, therapy to prevent human infection from the virus that causes AIDS.
