Scientists report a dramatic success in what may be the first documented rescue of a congenital brain disorder by transplantation of human neural stem cells. The research, published by Cell Press in the June issue of the ...
It’s hard to think of scientists in laboratories working toward solutions for medical problems without mice or other laboratory animals, but animals’ roles in at least one major research laboratory may soon be minimal.
A multi-institutional consortium including Duke University has created startlingly crisp 3-D microscopic views of tiny mouse brains -- unveiled layer by layer -- by extending the capabilities of conventional magnetic resonance ...
The retinas of most mammals contain two types of photoreceptor cells, the cones for daylight vision and colour vision, and the more sensitive rods for night vision. Nocturnal bats were traditionally believed to possess only ...
It has long been recognized that birds possess the ability to use the Earth’s magnetic field for their navigation, although just how this is done has not yet been clarified. However, the discovery of iron-containing structures ...
Cetaceans, the group of marine mammals that includes whales and dolphins, have demonstrated remarkable auditory and communicative abilities, as well as complex social behaviors. A new study published online November 27, 2006 ...
If eyes are "the windows of the soul," corneas are the panes in those windows. They shield the eye from dust and germs. They also act as the eye's outermost lens, contributing up to 75 percent of the eye's focusing power. ...
One of the major goals of cancer nanotechnology research is to develop nanoparticles that deliver cancer imaging agents and anticancer drugs specifically to tumors. Two new reports in the literature highlight new approaches ...
The world's largest Tyrannosaurus rex skull, unearthed nearly 40 years ago in eastern Montana, is now on display at the Museum of the Rockies at Montana State University in Bozeman.
By coating the surfaces of tiny carbon nanotubes with monoclonal antibodies, biochemists and engineers at Jefferson Medical College and the University of Delaware have teamed up to detect cancer cells in a tiny drop of water. ...
