Researchers have discovered a tiny protein without which the soil and lab-dwelling worm C. elegans can't deliver iron-rich heme taken in from their diets to the rest of their bodies or to their developing embryos. The finding reported in the May 27th issue of the journal Cell, a Cell Press publication, offers important insight into the transport of the essential ingredient in worms and other animals, including humans. Researchers say it also suggests a strategy for the development of drugs...

Using a tiny bloodless worm, University of Maryland Associate Professor Iqbal Hamza and his team have discovered a large piece in the puzzle of how humans, and other organisms, safely move iron around in the body. The findings, published in the journal Cell, could lead to new methods for treating age-old scourges - parasitic worm infections, which affect more than a quarter of the world's population, and iron deficiency, the world's number one nutritional disorder. Using C. elegans, a common...

Nitric oxide gas appears to directly impact the source of the classic, disabling pain crises of sickle cell disease, Georgia Health Sciences University researchers report. The short-acting gas helps unglue hemoglobin molecules that stick together, forming long chains that ultimately deform red blood cells and prompting a cellular pileup in small blood vessels and pain, said Dr. C. Alvin Head, Chairman of GHSU's Department of Anesthesiology. The findings get scientists closer to understanding...
