New evidence points to pollution as main cause of much coral reef destruction
...urse, been explored by other researchers, but with mixed results that Lapointe believes stemmed from such problems as poor choice of study sites. Some research teams, he says, have inadvertently studied the effects of experimentally increased nutrients in locations where nutrient levels were already so hig...Purdue engineers develop quick, inexpensive method to prototype microchips
... allowed them to separate specific proteins from a mixed solution. By manipulating the fiber's properties, scientists can identify or separate various types of molecules, such as proteins or antibodies, from solutions pumped through the chip. Depending on the properties of the fiber, liquids placed at o...BRCA mutations do not increase risk of colorectal cancer
... risk of colorectal cancer, however, have produced mixed and inconsistent results. In the current study, Gruber and colleagues tested blood samples from 1,422 patients with colorectal cancer and 1,566 control subjects without colorectal cancer for mutations in BRCA1 or BRCA2.

...lease all of its proteins. All of the proteins are mixed with beads, or tags, which "grab" just the DHFR-TS enzyme. Once DHFR-TS has been isolated, it's collected in a tube, concentrated and crystallized. The crystal, which is an ordered array of enzyme molecules, is subjected to a powerful X-ray beam.
