Epigenetic marker 5hmC opens door to studying its role in developmental disorders and disease
Nearly every cell in the human body carries a copy of the full human genome. So how is it that the cells that detect light in the human eye are so different from those of, say, the beating heart or the spleen?

Study: Heart repairs very early in life, but not as adults
(Medical Xpress) -- In a two-day-old mouse, a heart attack causes active stem cells to grow new heart cells; a few months later, the heart is mostly repaired. But in an adult mouse, recovery from such an attack ...
