...molecular biologist, McCarty will receive an honorary Doctorate of Science...
...zero in on the proteins that nurture tumor cells. In the past year alone, the FDA has approved three such drugs (for non-Hodgkin's lymphoma, breast cancer and leukemia). And more are in the pipeline, because scientists are becoming increasingly skilled at designing drugs that target specific, critical molecular processes that tumor cells need to survive. Herceptin, for example, takes advantage of the fact that most breast-cancer cells overproduce a certain growth-factor protein; the drug preferentially seeks out tumor cells in which the protein's concentration is high...
DoubleTwist's achievement reminds us that sequencing the human genome isn't the same as understanding it. What Celera and the federal project have been doing is figuring out the order of the DNA's chemical constituents--some 3 billion molecular "letters" that spell out the instructions for constructing a functioning human being...
...estimated 95% of those letters fall into the category of "junk DNA"--molecular gobbledygook that spells nothing at all. Discovering where the actual genes begin and end, therefore, is key to understanding their functions--and DoubleTwist has taken a step in that direction. Using a Sun Microsystems supercomputer, the company has taken raw data downloaded from the public project's growing online database and put them through a computational wringer...
...nation's livestock with antibiotics may be creating superresistant bacteria in humans. Here's new evidence: after contact with cattle on his family's farm, a 12-year-old Nebraska boy became infected with the same antibiotic-resistant strain of salmonella that had sickened the cows. Using a "molecular fingerprint," researchers confirmed that the cow bug and human bug were indeed one and the same...
