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...
New biologic treatment for tennis elbow may replace surgery for chronic sufferers

Heparin prepared synthetically could replace animal-derived drug
Researchers at Rensselaer Polytechnic Institute and University of North Carolina at Chapel Hill have discovered an alternative way to produce heparin, a drug commonly used to stop or prevent blood from clotting. The findings could enable the current supply of the drug ?now extracted from animal tis...
