Johns Hopkins scientists have developed a reliable method to turn the clock back on blood cells, restoring them to a primitive stem cell state from which they can then develop into any other type of cell in the body.

When the human genome was sequenced, biologists were surprised to find that very little of the genome—less than 3 percent—corresponds to protein-coding genes. What, they wondered, was all the rest of that DNA doing?

Some people and animals grow arteries that allow blood to bypass blockages in the heart. But to engineer these bypasses to serve as lifelines, scientists first need to understand how they work. Researchers have now modeled ...
