The implications for crop science of such findings could be considerable, said Chory.

...n mammalian systems, so it is quite interesting to discover that they also play an important role in plants and are regulated similarly," Assmann says. "The more you can understand about how plants function on the molecular level, the more likely it is that you can use breeding or biotechnology to develop mo...Researchers identify fatty-acid oxidation as additional source of nutrients in the placenta
... Southwestern Medical Center at Dallas have helped discover that an expectant mother's placenta nourishes her fetus by oxidizing fatty acids in addition to providing the developing fetus with glucose previously believed to be the placenta's only energy source. The findings will appear in the June issue of th...Hebrew University researcher wins prize for work leading to new anti-cancer drugs

"It shows that aldolase and perhaps other proteins can hold dual roles in the cell. We should keep that possibility in mind when assessing the possible function of proteins."...Energy department awards $9 million for energy-related genomic research
