Study uncovers bacteria's worst enemy

...al contamination from nuclear waste and processing activities may depend more upon how resistant the bacteria are to chemicals than to how tolerant they are to radioactivity. The results of a recent Laboratory study may help make bacterial bioremediation a more widespread method for cleaning up sites contaminat...

Measles Deaths Worldwide Drop By Nearly 40% Over Five Years

...ugh routine services or supplementary immunization activities (SIAs) every three to four years. The SIAs have proven especially effective. From 1999 to 2003, more than 350 million children throughout the world were vaccinated against measles through SIAs. As measles wards shut down all over the African contine...

Researchers develop assay that could be applied to drug screening

...CME is of fundamental importance for many cellular activities including receptor down-regulation, nutrient uptake and maintenance of signal transmission across nerve cell junctions. Mis-regulation of CME has been implicated in some types of cancer and neuro-degenerative disease and the protein machinery of CME ...

Changing ecosystems throw scientists mega-challenges

The report encourages NSF to maintain its foundation-wide emphasis on investigations of coupled human and natural systems, as currently embodied in the Biocomplexity in the Environment pr...

Stanford gut check shows diversity of intestinal ecosystem

...unities may indicate where they have been and what activities they have pursued in terms of travel, diet, antibiotic use and the like. Relman emphasized that the study looked at only a limited number of individuals and examined only one genetic feature of the microbes, so there are many studies that must and w...

Too much water may be as dangerous as too little during long-distance athletic events

Disabling gene defuses rheumatoid arthritis in mice

...rrently trying to discern more details of Foxo3a's activities in neutrophils, including the pathways the gene activates to block apoptosis. They will also be looking for drugs that inhibit Foxo3a and testing them in the mice as potential anti-arthritis drugs. ### Jonsson H, Allen P, Peng SL. "Inflammatory art...

NYU, Rockefeller researchers find complexity of regulation by microRNA genes

...ripts and that many microRNAs can coordinate their activities to regulate specific target genes. The paper contains detailed genome-wide predictions for all human microRNAs as well as tissue-specific predictions. Several predictions were validated experimentally. The findings demonstrate an unforeseen staggerin...

ORNL, UC Berkeley unravel real-world clues to Earth's mysteries

...es, scientists know little about the structure and activities within these communities. This is because the commonly used artificially cultivated organisms lack the diversity found in nature, so potentially critical community and environmental interactions go unsampled.

Arthritis: What Wnt wrong?

...sociate. Nakamura has been studying the biological activities and signaling pathway of a Wnt-related gene that causes severe joint degenerative disease in humans. "More specific analyses such as gain-of-function and loss-of-function study of Wnt-7b will give us a clue which Wnt-7b would be an important pathobi...
