When new species evolve, they leave genetic evidence behind in the form of “breakpoint regions.” These regions are sites on the genome where chromosomes broke…
The ends of the chromosomes, the telomeres, are repetitive DNA sequences that shorten every time a cell divides during the process of duplicating its genome….
These old cells were reprogrammed in vitro to induced pluripotent stem cells (iPSC) and to rejuvenated and human embryonic stem cells (hESC): cells of all…
Researchers at Wake Forest Baptist Medical Center's Institute for Regenerative Medicine, collaborating with other institutions, report in Experimental…
Research into differentiation has led to a variety of breakthroughs as stem cell researchers harvest cells from one part of the body and genetically adapt them…
The cerebellum is far more intensively involved in helping us navigate than previously thought. To move and learn effectively in spatial environments our…
Using a mouse model that mimics the devastating condition in newborns, the researchers found that high levels of the protective protein, Nmnat1, substantially…

WHAT: Epstein-Barr virus (EBV) infects nine out of ten people worldwide at some point during their lifetimes. Infections in early childhood often cause no…
Long-lived fruit flies offer Salk scientists clues to slowing human aging and fighting diseaseOne of the few reliable ways to extend an organism's lifespan, be…
The vast majority of the human genome consists of DNA without any apparent function, so-called “junk DNA”. A study conducted by the scientists Dr. Laurence…
H. pylori are the only bacteria known to survive in the human stomach. Infection with the bacterium is associated with an increased risk of gastric cancer, the…
The tangles, which were first identified in the early 1900s by German psychiatrist and neuropathologist Aloysius Alzheimer, are formed when changes in a…
