Signal gradients in 3-D guide stem cell behavior
Scientists know that physical and biochemical signals can guide cells to make, for example, muscle, blood vessels or bone. But the exact recipes to produce the desired tissues have proved elusive.

(Phys.org) —Synthetic biology is a science that aims to harness natural biological processes for other uses, such as in the manufacture of fuels and drugs. Now, synthetic biology researchers in the U.S. have developed a ...
In all the centuries that humans have studied chemical reactions, just 36 basic types of reactions have been found. Now, thanks to the work of researchers at MIT and the University of Minnesota, a 37th type of reaction can ...
