City Council Approves DNA Research...
...Cambridge City Council last night ensured the survival of recombinant DNA research within the city limits as it ratified the recommendations of the Cambridge Experimentation Review Board (CERB), the citizen’s panel that recommended the controversial research be allowed to continue under special guidelines...
...Something you know is easy: it's a password, a personal identification number that no one else should have. Something you have is an ATM card or an ID card at work. Something you are can be your handwriting, your fingerprint or your DNA sample, depending on how detailed you want to get. Some very advanced systems use GPS to pinpoint where you are, but that's a different level of technology...
...phytochemicals with 100 times the antioxidant punch of vitamin C. Laboratory experiments suggest that one group of polyphenols in green tea called catechins may inhibit the growth of new blood vessels, which some scientists think may help prevent cancer by depriving early tumors of nourishment. (Catechins may also prevent DNA damage caused by carcinogens from occurring in the first place.) Indeed, population studies in China link drinking green tea daily with a lowered risk of stomach, esophageal and liver cancers. Studies from Japan show that consuming 10 cups a day may reduce the risk of heart disease. If that much...
...accidental discovery, but it could hardly be called serendipitous. By adding a single gene to its DNA, Australian researchers turned a mousepox virus that normally causes only mild symptoms in rodents into a virulent killer that wiped out all their lab mice in less than 10 days. Alarms were sounded, not over the prospect of mouse plague but out of concern that rogue scientists might use the technique to create human pathogens even more lethal than anthrax or smallpox...
