A protein in the blood of young mice that seemed to rejuvenate older animals may do the opposite

The “region-specific” pluripotent cells are easier to grow in vitro and graft into an embryo when injected into the right spot

In 2011, Paul Tesar, a professor at Case Western Reserve School of Medicine, worked with collaborators to come up with a method of producing massive numbers of mouse stem cells that are capable of turning into oligodendrocytes, the cells that produce myelin, the protective coating on nerve cells.

This year, I've been very fortunate to be a part of the inaugural class of the Presidential Leadership Scholars (PLS) program, which brings together 60 leaders from around the country to work on projects designed to create significant social impact and change.

It has long been known that bacteria can “talk” to one another, but now a study has shown mammalian cells may similarly coordinate group action

Human testing is under way or poised to start for brain cancer, multiple sclerosis, spinal injury, type 1 diabetes and "Lou Gehrig's" disease

Whenever one examines any area of scientific inquiry, there are two important things to understand: where the science is today, and where it may lead us in the future.

A call by scientists to halt precision gene editing of DNA in human embryos would allow time to work out safety and ethical issues

New inner-ear drug delivery systems could stop relentless ringing or restore lost sound sensitivity

New techniques in orthopedic surgery aim to unleash the body's own healing power

Haruko Obakata caused a sensation earlier this year with papers, now discredited and retracted, that claimed a simple method for creating pluripotent stem cells
