'Computer-chemistry' yields new insight into a puzzle of cell division

...further. They did so by using a different software program that could identify the highest and lowest places on the molecules' surfaces, and where "highest" on one might fit into the "deepest" on the other. "That's not easy, because there is no point of reference on those complicated shapes," Rudolph said. ...

Study finds that nutritionally enhanced rice reduces iron deficiency

...Plus, an international, interdisciplinary research program focused on breeding crops for better nutrition and led by IFPRI and the International Center for Tropical Agriculture (CIAT), will continue to work with these research findings and partners to increase the level of nutrient density in rice to be even...

DNA gene vaccine protects against harmful protein of Alzheimer's disease

...amyloid-beta 42 genes attached to other genes that program cells to make the protein. The particles were then injected with a gene gun into the skin cells of the mice's ears using a blast of helium. After receiving 11 injections over several months, the mice showed a high level of antibodies to amyloid-bet...
