...ctric generating stations. Their dust-sized larvae attach to the interior of the pipes, then grow to approximately the size of a lima bean, clogging the pipes to the point that theyre unusable. Zebra mussels immigrated to the United States in the mid-80s as stowaways on foreign ships. Although first discov...'Imprinted' gels hold promise for future medical devices
... The approach attempts to mimic how some molecules attach to "binding sites" on other molecules, similar to the way in which a key fits into a lock. Such binding is critical to various biological processes. Each binding site, however, must possess the proper shape and other characteristics for it to bind to...... immunosorbent assay - is that there is no need to attach fluorescent tags to molecules. This could prove very useful in testing how well candidate drugs bind to their targets, since drugs typically are so small that attaching fluorescent labels interferes with their binding to a protein or enzyme. Cote not...Slight molecular tweak, and flu virus becomes a killer
...surface landscape of a virus is the key it uses to attach to host cells and co-opt their reproductive capabilities. The surface proteins of flu viruses change readily to escape detection by the human immune system. The new research suggests, however, that such changes may also trigger changes that can tran...Bizarre new protein blocks a real-life terminator
...phan concentrations are high, tryptophan molecules attach themselves to the binding sites on TRAP, activating TRAP and allowing it to bind to mRNA, which causes the mRNA-terminator to form. This essentially turns off the genes needed to produce tryptophan,`` notes Valbuzzi, lead author of the Sept. 14 Scien...How bacteria harden their "armor"
...antibiotics like polymyxin or certain peptides, to attach to the outer coat -- a key step in the antibiotic's process of piercing the bacterial coat to kill it. According to Raetz, positively charged peptides are components of many antibiotics, including those employed by the body's innate immune system, ...Scientists discover how some viruses take strong hold of cells
... binding sites on a virus and block its ability to attach to cells. These haven't worked very well, Freimuth suggests, because the double hold the virus forms with the cell makes it hard for these single molecules to compete. But perhaps administering receptor-like molecules with double binding sites would ...Controlled nerve growth factor aids brain cell transplant
...onnecting cells the engineers hoped would grow and attach to others cells in the rat brains. They also created some neo-tissue clusters without the NGF microspheres, as controls to gauge the activity of transplanted cells without the presumed benefits of growth-enhancing microenvironments.
