Stem cells replace stroke-damaged tissue in rats

Effective stem cell treatment for strokes has taken a significant step forward today (09 March) as scientists reveal how they have replaced stroke-damaged brain tissue in rats. The team of scientists is funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and led by Dr M...

How to make microwaves on a chip to replace X-rays for medical imaging and security

Is microwave radiation the nondestructive imaging technology of the future? Microwaves with frequencies from a few hundred gigahertz (GHz) up to slightly over 1 terahertz (THz), penetrate just a short distance into surfaces without the ionizing damage caused by X-rays. The technology could be used...

Penn researchers replace organ in adult mice using 'single-parent' stem cells

Researchers at the University of Pennsylvania School of Veterinary Medicine have derived uniparental embryonic stem cells - created from a single donor's eggs or two sperm - and, for the first time, successfully used them to repopulate a damaged organ with healthy cells in adult mice. Their findi...
