New Cornell-led research finds “little to no evidence” of a link between a person’s normal blood levels of vitamin D and risk of getting COVID-19, or the severity of an infection, in the most comprehensive study of its kind to date. Multiple studies had suggested an association between vitamin D […]

The Vanderbilt Institute for Clinical and Translational Research (VICTR) has been awarded a major federal grant to lead a national trial of treatments targeting the Renin Angiotensin Aldosterone System (RAAS) in patients hospitalized with COVID-19. Comprised of the hormones renin, angiotensin and aldosterone, RAAS is essential for the regulation of […]

Chimpanzees and bonobos diverged comparatively recently in great ape evolutionary history. They split into different species about 1.7 million years ago. Some of the distinctions between chimpanzee (Pan troglodytes) and bonobo (Pan paniscus) lineages have been made clearer by a recent achievement in hominid genomics. A new bonobo genome assembly […]

University of Alberta researchers have uncovered a link between the expression of the protein galectin-9 (gal-9) and whether a cancer patient will benefit from immunotherapy. The discovery could help inform physicians about which patients will likely respond to immunotherapy, and lead to better treatment options. Shokrollah Elahi, a member of […]

Researchers report that one kind of perceptual learning can occur in memory-impaired persons who do not actually remember what they learned. There are many types of memory, but fundamentally, humans remember in two ways. Declarative memory consists of ordinary recollections consciously summoned from the brain. It is dependent on the […]

When someone is diagnosed with cancer, the epicenter of the tumor is easily identifiable, but in 1 to 2 percent of cases, the primary site of tumor origin cannot be determined. Because many modern cancer therapies target primary tumors, the prognosis for a cancer of unknown primary origin is poor, […]

What if a cancer patient could receive life-saving cellular therapy within days of diagnosis rather than weeks?
