...every auto company in the world is desperately seeking an engine to replace the internal-combustion machine that has been powering cars, consuming oceans of fossil fuel and polluting the universe for about 100 years. GM, in fact, will begin selling a battery-powered electric car in California this year. California, locked in a perpetual automotive smog, requires that by 2003, 10% of the cars offered for sale in the state produce zero emissions; many states are expected to follow suit...
...space has made a giant leap forward, and many churches are nervous about attacks on creationism. Scientists have not claimed they have found definitive proof of extraterrestrial life, yet the microscopic evidence is being treated as such by most of the media. Even if scientists did find a bacterial fossil that was truly from Mars, that's still a long way from E.T. phoning home or from aliens blowing up our major cities. Darn.

...NASA and university researchers revealed that this well-traveled, 4.2-lb. stone--about the size of a large Idaho potato--had brought with it the first tangible evidence that we are not alone in the universe. Tucked deep within the rock are what appear to be the chemical and fossil remains of microscopic organisms that lived on Mars 3.6 billion years...
...weakest and most controversial parts of the evidence, the panel of scientists at the press conference cited complex chemicals found close by or inside the carbonate globules. These included polycyclic aromatic hydrocarbons (PAHS)--organic molecules that on Earth are formed when microorganisms die and decompose (but also when certain fossil fuels are burned)--and iron sulfides and magnetite, minerals that are often (but not necessarily) produced by living organisms...
...strategy for exploring the finding. Said Clinton: "I am determined the American space program will put its full intellectual power and technological prowess behind the search for further evidence of life on Mars." The scientists found that the pinpoint-sized flecks contained hydrocarbons, which may be the fossil remains of Martian bacteria, single-celled life forms that thrived on the red planet 3.5 billion years ago. The meteorite, called Allan Hills 84001, contains organic molecules called polycyclic aromatic hydrocarbons (PAHs) which in this case are said to be the byproducts of metabolic processes. The PAH molecules were recovered from cracks...
