dendrimers. "It turns out that they cause the same permeability and, in general, they cause membrane destruction as well," said Banaszak Holl. Neutral polymers, however, did not damage membranes. Both Leroueil's work and the earlier research used mo...
Not-for-profit publishers call NIH public access rule a missed opportunity
...f NIH created an enhanced search engine that works like
Google to crawl the journals' full text articles and link to the final published articles residing on the journal websites. This would offer significantly more assistance to those seeking medical research results than a database of NIH-funded manuscr...

Viral protein influences key cell-signaling pathway
...ed women to children through breast milk. HTLV-1, like
its cousin HIV, inserts its genetic information permanently into the DNA of a T lymphocyte and remains there for the life of the cell. HTLV-1 infection is also lifelong. A hallmark of HTLV-1 infection is the proliferation of T lymphocytes. This sets...
Flocking together: Study shows how animal groups find their way
...dividuals to form close-knit, evenly spaced groups like
those of real animals, which pay a high price -- such as being eaten -- if they stray from their group. Second, a few animals were programmed to have a preferred direction, as if aware of a food source or other valued destination. These animals were...

Robot-based system developed at Carnegie Mellon detects life in Chile's Atacama desert
...e detection system worked very well, and something like
it ultimately may enable robots to look for life on Mars," said Alan Waggoner, Atacama team member and director of the Molecular Biosensor and Imaging Center at the university's Mellon College of Science. The "Life in the Atacama" 2004 field season ...
Alaskan puzzles, monitoring provide insight about North Pacific salmon runs

humans and elk and deer, which suffer from a prion disease called chronic wasting disease. Surewicz stresses, however, prion infection between species is still rare. "Fortunately, transmission by eating is very ineffective. There have been hundreds ...
Scientists discover how plants disarm the toxic effects of excessive sunlight

Vibrio and Pseudomonads have systems to sense and protect themselves from singlet oxygen, says Donohue. Other reactive oxygen species - often called "free radicals" - are thought to be at the root of many debilitating diseases. "There have been cons...
Gene Therapy Cures Inherited Liver Disease In Rats
