The project features innovations in heterogeneous computer graphics, tangible human-computer interaction, interactive animated characters, and mo...Ready, set, mutate and may the best microbe win
...g three weeks of the test. The research included a raft of additional experiments as well. The team characterized each of the mutant proteins to document precisely how it aided in metabolic regulation. The fermentor experiment was repeated and the same mutations and no others were observed to develop ag...Natural resources and the economy: hand in hand
...inesses and industries--from timber and farming to raft guiding and hotel management--as well as a distinct sense of place and quality of life which attracts more and more people to the area. With increased population--and the development that follows it--comes the responsibility to make sure that economi...UW-Madison researchers find new way to 'sweeten' key drugs
...the discovery of a simple process that may yield a raft of promising new agents to treat cancer and the most stubborn antibiotic-resistant infections. "The work opens the door to a variety of new opportunities in the natural product drug arena," says Thorson. "There are a number of antibiotics and antic...With record resolution and sensitivity, tool images how life organizes in a cell membrane

...ot trail, the researchers carried in an inflatable raft during the summer months in order to collect sediment samples from the middle of the lakes. The lakes range from 8.2 feet (2.5 meters) to 34.5 feet (10.5 meters) deep. The scientists collected sediment in cylindrical plastic tubes, gathering severa......s enriched in the cholera toxin B subunit, a lipid raft molecule, as well as the stem cell marker CD133. The researchers had seeded the outside of the progenitor cells with microscopic markers, quantum dot nanocrystals, and watched as the dots were taken into the cells and delivered specifically to th...Caribbean frogs started with a single, ancient voyage on a raft from South America
