Protein movement can be simulated three times as fast than had been thought possible up to now. Researchers from Groningen achieved the gain in speed by leaving out the calculations concerning hydrogen atoms. Meanwhile research groups around the world are adapting their simulation programs.
Up until now researchers calculated all of the positions of atoms in a protein molecule after two femtoseconds. A femtosecond is one millionth of a billionth of a second. The research from Groningen revea
Primates found in Brazil’s Amazon rain forest
Conservation International announced today the discovery of two new species of titi monkey in Brazil’s Amazon rain forest. The findings are published in a just-released special supplement to the journal Neotropical Primates.
They were described by Marc van Roosmalen, a primatologist at Brazil’s National Institute for Amazon Research (INPA), his son, Tomas van Roosmalen, and Russell Mittermeier, president of Conservation Internat
Researchers at the University of Toronto and Mount Sinai Hospital have identified a protein that plays a critical role in the regulation of “natural killers cells” in the immune systems battle against foreign and diseased cells.
“Our research is a small part of the larger problem of how viruses and diseased cells ravage the body and circumvent our immune system,” says Kathleen Binns, a U of T doctoral student in medical genetics and microbiology and an author on a paper in the June 20
A newly established national biomedical center at Cornell University is reporting its first major advance: a new way of measuring, or “visualizing,” proteins. The new technique will hasten the transformation of the human genome project’s blueprints of life into a comprehensive view of the biochemical and physiological circuitry that interconnect to form entire organisms.
The technique, which determines the structure of a protein by measuring the distances between atoms in the molecule at g
The emergence of mutant frogs with extra arms and legs may smack of a low-budget sci-fi script. But it is a reality, and a new study provides more evidence that ultraviolet radiation could be responsible. The findings are reported in three consecutive papers in the July 1 print issue of Environmental Science & Technology, a peer-reviewed journal of the American Chemical Society, the worlds largest scientific society.
Concern has been mounting for years over the depletion of the ozone
Little shavers could prove key in nanoelectronics
Theyre cute little shavers, and they could play a key role in the “small” revolution about us.
Theyre boron nanowhiskers, the worlds first such crystalline nanowires, made by chemists at Washington University in St. Louis.
Reporting in the May 1 issue of the Journal of the American Chemical Society (JACS), graduate student Carolyn Jones Otten, her advisor William. E. Buhro, Ph.D., Washin
