STEM cells from the human brain that were transplanted into the brains of newborn rats have matured and are able to function just like native rat cells. The breakthrough demonstrates the potential for people with brain damage, caused by epilepsy or Parkinson’s for example, to use their own brain stem cells as a treatment.

Cooling Neutron Star
Explanation: Supernova remnant Cassiopeia A (Cass A) is a comfortable 11,000 light-years away. Light from the Cass A supernova, the death explosion of a massive star, first reached Earth just 330 years ago. The expanding debris cloud spans about 15 light-years in this composite X-ray/optical image, while the bright source near the center is a neutron star (inset illustration) the incredibly dense, collapsed remains of the stellar core. Still hot enough to emit X-rays, Cass A’s neutron star is cooling. In fact, 10 years of observations with the orbiting Chandra X-ray observatory find that the neutron star is cooling rapidly, so rapidly that researchers suspect a large part of the neutron star’s core is forming a frictionless neutron superfluid. The Chandra results represent the first observational evidence for this bizarre state of matter.
