New stem cell-based vascular grafts could revolutionize cardiac surgery
Sources for small-diameter vessels, most commonly used for the coronary bypass surgery, are limited. This work is an important step in advancing stem cell technologies for bioengineering vascular grafts for cardiac vessel repair and their clinical translation.
Scientists Discover Protein Key to Bacteria's Survival in Extreme Environments
Scientists have discovered a protein that enables bacteria to shut down into dormant spores under extreme conditions. The process, which enables the bacteria to become practically indestructible, explains why bacteria can survive in uninhabitable places such as under the permafrost, in the depths of the ocean or in outer space.
French Scientists Studying Neanderthals Discover New Blood Type and Possibly Key to Human Evolution in Red Blood Antigens
Researchers out of France have identified a unique antigen in red blood cells that may have contributed to the downfall of Neanderthals.
Research findings solve the paradox of how the immune system balances speed and precision
Germinal centers are high-speed evolution machines. Tiny clusters in the lymph nodes, germinal centers refine antibodies through mutation and expansion until they produce high-affinity B cells adapted to keep different pathogens in check. But rapid evolution should come at a cost. Most mutations are deleterious, so constant mutation during every cell division, coupled with unchecked proliferation, should be a recipe for disaster. How B cells somehow rapidly mutate and improve all at once was a long-standing mystery.
Early-Onset Breast Cancer Rising in Younger Women, Study Finds
Study reveals increasing breast cancer rates in US women under 40, with geographic and demographic differences suggesting environmental factors may play a role
