... nutrition. For example, over three billion people worldwide suffer from Iron and/or Zinc deficiencies. Food consumption studies suggest that doubling the Iron in rice can increase the Iron intake of the poor by 50 percent. Rice is a staple food in many of the countries with widespread Iron deficiencies in hu...

Mapping the protein world

...RP/wARP has made the life of structural biologists worldwide a lot easier and will do even more so once the new features planned under the NIH grant have been implemented."

How bad is malaria anemia? It may depend on your genes

...mia that kills almost half of the 2 million people worldwide who die each year of malaria. The culprit is a protein cells make in response to inflammation called MIF, which appears to suppress red blood cell production in people whose red blood cells already are infected by malaria parasites. The parasite t...

Statins stop hepatitis C virus from replicating

...ournal/hepatology . Currently, 170 million people worldwide are infected with HCV.

Report warns about carbon dioxide threats to marine life

...fs and Other Marine Calcifiers," warns that oceans worldwide absorbed approximately 118 billion metric tons of carbon between 1800 and 1994. Oceans are naturally alkaline, and they are expected to remain so, but the interaction with carbon dioxide is making them less alkaline and more acidic. The increased aci...
