...mory to mood and perception. Too much glutamate is believed to contribute to conditions such as Alzheimer's and Parkinson's disease. The research is published in the May 30-June 3 on-line early edition of the Proceedings of the National Academy of Sciences.

...researchers point to cases in which reservoirs are believed to have facilitated the rapid spread of invasive species. The authors note that reservoir construction often leads to many-fold increases in the area of standing water in a region and that reservoirs typically replace varied stream habitats with habi...Other highlights in the June 1 JNCI

Because FPR, which was believed to be mainly involved in proinflammatory and antibacterial responses, was discovered to be expressed by some glioma cells, Ji Ming Wang, M.D., Ph.D., of the National Cancer Institute, and colleagues investigated the relationship between FPR and the b...Study: Plants use dual defense system to fight pathogens

The Flores Man is believed to have derived from a more ancient hominid lineage, Homo erectus, which diverged from modern humans some two million years ago, as compared to Neandertal, which diverged 500,000 years ago.
