A pilot study of a system for harvesting kidneys from non-heart-beating donors where attempts of resuscitation after a witnessed out-of-hospital cardiac arrest have failed (uncontrolled NHBDs) resulted in 21 successful kidney transplants -- a 10 percent increase in the transplantation rate -- over 17 months. Researchers have shown that retrieval from uncontrolled NHBDs may provide a valuable source of organs and could help counter the shortage of kidney grafts in France.

http://www.sciencedaily.com –
Despite medicines for patients with vascular disease, a large international study shows these patients have a surprisingly high rate of recurring strokes, heart attacks and hospitalizations as well as mortality. Patients in North America experienced an above-average rate of these events. Patients in Eastern Europe had the highest rate, and those in Australia and Japan had the lowest.

(American Museum of Natural History) In a new Bulletin of the American Museum of Natural History, James Miller revises the taxonomy of the Dioptinae, a subfamily of moths that have conquered the day in the tropical Americas. The roughly 500 described dioptines have a wide diversity of wing types -- from blue to yellow-stripes to clear -- and converge with another group of diurnal insects that probably evolved from a nocturnal, brown moth, the butterflies.

No Such Thing As Ethnic Groups, Genetically Speaking, Researchers Say
http://www.sciencedaily.com –
Central Asian ethnic groups are more defined by societal rules than ancestry. Researchers found that overall there are more genetic differences within ethnic groups than between them, indicating that separate "ethnic groups" exist in the mind more than the blood.

http://www.sciencedaily.com –
Biophysicists in Germany are leading an effort to develop and apply models of the so-called lateral-line system found in fish and some amphibians. This sensory organ enables an animal, even in murky water, to map its surroundings and recognize other animals. In a new study, the researchers report mathematical models that capture essential elements of the system, agree with experimental data, and could be easy to implement technically, as in robots.

http://www.sciencedaily.com –
Some slow-moving faults may help protect against destructive earthquakes, suggests new research. Until now, geologists thought when the crack between two pieces of the Earth's crust was at a very gentle slope, there was no movement along that particular fault line. Now geoscientists have found that such a low-angle normal fault in Italy is moving slowly and steadily.
