URI scientists study life buried deep beneath the ocean floor
... buried oceanic sediment. Microorganisms have been recovered from depths as great as a half-mile below the seafloor and have been estimated to constitute one-tenth to one-third of Earth's living biomass. URI oceanographers Steven D'Hondt, Scott Rutherford, and Arthur J. Spivack are studying the activity of ba...Ocean ecosystems only altered following two great mass extinctions

These results further defined the appropriate dose for a phase II trial of gemcitabine in superficial bladder cancer and such a trial is ongoing. A large phase III trial designed to fulfill FDA requirements for approval of gemcitab...New technology creates 'super soap'

In three clinical studies, the bacteria attachment to the hands washed with the MAT-containing soap was reduced by a statistically significant 50-58% relative to the hands washed with placebo or com...First primate archaeological dig uncovers new tool development links
...h they used as anvils. The researchers last fall, recovered 479 stone pieces, chips of granite, laterite, feldspar and quartz broken from the hammers. Some of the stone by-products of the chimpanzee nut cracking are similar to what we see among the technologically simplest Oldowan [hominid] sites in East Afr...Clonal human (hNT) neurons re-establish connection in rats with severe spinal cord injury
... All seven animals in the delayed transplant group recovered electrical activity in the spinal cord neurons that control muscle movement. Only two of nine animals in the immediate transplant group did. In addition this electrical activity known as motor evoked potentials or MEPs measured much stronger in ...... repeated tone presentations, control mice quickly recovered from this fear reaction. CB1-deficient mice, in contrast, showed a weak reduction of fear (Fig. 2). Noteworthy, acquisition and consolidation of fear memory were completely normal in CB1 knock-out mice: the mice successfully learned to associate the ...First drug developed for widespread use against botulism

Since the screening procedure uses only the binding portion of each antibody, they then had to generate full length antibodies to determine...Bacterial alterations source of persistent COPD lung infections

New technology involving DNA testing enabled investigators to study the molecular signature of the bacteria, resulting in extremely accurate identification.
