...wouldn't want to live as long as Methuselah, myself. But I would like to reach old age alive and kicking. My hope is that the science of life will mature fast enough so that 30 years from now, when my sons begin to ask those eternal questions about growing old, I can look at them and say, "I recommend...
Scientists are also focusing on the differences between two types of fat cells, known as brown and white. The former, active in young mammals (including humans), convert fat into heat rather than storing it. That's crucial in newborns, whose temperature-regulation systems aren't fully formed. As we age, the brown cells become inactive and the white, which convert dietary fat to body fat, take over. Several research teams have found that by reactivating the brown cells in an adult animal with medication, they can burn off fat dramatically. Now the doctors are looking for a genetic switch that...
...technology is not enough. Just as critical are changes in attitudes and lifestyles. Brad Allenby, AT&T's vice president for environment, safety and health, believes our move from the industrial age to the information age could help enormously. At last count, he says, 29% of AT&T's management force telecommuted, meaning less reliance on cars. This, Allenby speculates, could be part of something bigger--a shift in our view of what enhances our quality of life. Maybe we'll put less value on things that use lots of materials--like three cars in the family driveway--and more...
...degrees]F) warmer than it is now. This time period is regarded as one of the most benign weather regimes in history. To find temperature swings at the upper end, you have to go back 10,000 years, to when the earth was exiting the last Ice Age. Temperatures during the Ice Age were 5[degrees]C (10[degrees]F) cooler than they are now, and there was a series of incidents during which global temperatures changed as much as 10[degrees]F in a matter of decades. If that were to happen now, expanding oceans might flood coastlines...
...makes no sense to overreact to the prospect of global warming, but it makes no sense to ignore it either. A prudent policy that stresses conservation and alternate energy sources seems to me to be wise insurance in an uncertain age. After all, our grandchildren will thank us for developing high-mileage cars, energy-efficient appliances and cheap solar energy, no matter how the future of global warming plays...
