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.

(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.

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.

New research has found a drug target that suggests a potent way to kill colon cancers that resist current drugs aimed at blocking a molecule found on the surface of cells.

A novel natural product yields potential new ways to fight diseases. Researchers have deciphered the highly unusual molecular structure of a naturally produced, ocean-based compound that is giving new understanding of the function of mammalian nerve cells.
