This new human blood-brain barrier on a chip gets its surprising edge by giving astrocytes 3D living space GEORGIA INSTITUTE OF TECHNOLOGY A scrupulous gatekeeper stands between the brain and its circulatory system to let in the good and keep out the bad, but this porter, called the blood-brain barrier, also blocks trial drugs to...
Mass General Hospital researchers identify new ‘universal’ target for antiviral treatment
MASSACHUSETTS GENERAL HOSPITAL BOSTON – As the coronavirus outbreak shows, viruses are a constant threat to humanity. Vaccines are regularly developed and deployed against specific viruses, but that process takes a lot of time, doesn’t help everyone who needs protection, and still leaves people exposed to new outbreaks and new viruses. Now, researchers at Massachusetts...
How cranberry juice can prevent UTIs
Cranberries have long been considered a folk remedy for the prevention of urinary tract infections. Now a team of researchers including scientists at the University of Georgia think they know why. UGA scientists, working with colleagues at the University of Mississippi, provided crucial information in the discovery of a class of oligosaccharides—a type of complex...
