...insistent patter of a HealthWatch Model 9000 alarm clock. "Today is Monday, and the time is 6 a.m.," the little box chirps. Angela stares at its smooth, blue face long enough for the embedded microlaser to scan the back of her eye. "Ocular pressure, blood pressure and carbon-dioxide levels normal," the alarm clock reports. "But you are dehydrated. I'll signal the refrigerator to fix you an electrolyte cocktail...
...question is more important than the literal, but the literal is irresistibly short: No, unfortunately not. Humans will have at our disposal as much gasoline as we can burn in the 21st century. Nor are we likely to run out of heating oil, coal or natural gas, the other carbon-based fuels that have powered industrial civilization for 200 years...
...While many find fault with this hypothesis - the skull is a lone example and does not contain the correct matter for carbon-dating - anthropologists around the world agree that decisive evidence of the skull's geographic ancestry will be produced by testing its DNA and comparing it to that of other Negroid peoples, such as Australian aborigines and Africans. The remains of the woman who's spawning the debate, nicknamed Luzia, were found in 1975 outside Belo Horizonte, Brazil's third largest city, and were in storage in a Rio museum for a quarter of a century. That sound...
...Carbon dioxide, or CO2, lasers have been widely used since 1994 to bloodlessly eradicate wrinkles and sun damage by vaporizing the upper layer of skin, thus stimulating the underlying collagen fibers to rejuvenate the skin. Some 170,000 people had laser resurfacing done last year, making it by far the most popular laser procedure. Though chemical peels do essentially the same thing--and cost less than the average $2,500 to $3,000 for laser resurfacing--lasers have the advantage of being more controllable, since chemicals are absorbed at different rates by different skin...
...tons the year before. Is that an impressive improvement? Or is 6,600 tons still too much? Is there a permissible discharge level? And where did the discharges take place? What about emissions of greenhouse gases? Oil companies may brag about meeting tough targets on cutting emissions of carbon dioxide. But some advocacy groups say those targets shouldn't be accepted as goals because the ultimate goal should be an end to fossil-fuel...
