...Just last week, the Food and Drug Administration warned doctors that protease inhibitors, a key ingredient in the new therapies, can cause diabetes--in addition to known side effects that include liver complications and debilitating nausea. Are the benefits worth the risks? Could overuse of antivirals unleash a new strain of drug-resistant superviruses? Will the availability of a morning-after treatment make people relax their guard? Will there be a widespread return to the risky sexual practices that preceded the AIDS epidemic? These and a host of other questions will be addressed next month at a special meeting...
...check for decades, the Centers for Disease Control confirmed Wednesday. The development, first reported by the Dallas Morning News, may leave doctors without an adequate way to kill the organism and could eventually lead to an unstoppable wave of deadly infections in hospitals. First discovered in Japan, the new strain showed an "intermediate" level of resistance to the antibiotic vancomycin, which has been used worldwide to fight off Staphylococcus and other stubborn types of bacteria for the past 30 years. Dr. Francisco Sapico, an infectious disease specialist at USC's Rancho Los Amigos Medical Center, told TIME Online the possibility...
Those decades came to ugly conclusions, alas, but this one is likely to be different. Why? Unlike most earlier expansions, which crashed to earth when the Federal Reserve raised interest rates sharply to cool down an overinflating economy, the 1990s-style growth shows few signs of strain. To the contrary, a rare combination of price stability and moderate gains in the gross domestic product has made this upturn remarkably steady. Many economists say this tranquillity is owing to the Federal Reserve's strategy of tightening credit in the middle of the decade before prices could turn up. "Inflation...
From the outside, the new strain of mice looked a little, well, lumpy. But when scientists peeled back their fur and skin, what had seemed like extra baggage in the shoulders and hips turned out to be pure muscle--two to three times the muscle mass of the average pip-squeak rodent. These were not your ordinary genetically engineered laboratory mice; these were Mighty Mice...
...colleagues at the Johns Hopkins School of Medicine didn't set out to create muscle-bound lab specimens. As reported in last week's Nature, they wanted to find out how a particular protein, a growth factor called myostatin, regulates the development of tissue. So they produced a strain of mice in which the gene that codes for myostatin had been deleted, or "knocked out." The resulting mutant animals grew up normal in every way--except for their extraordinarily well-developed musculature...
