...Unlike solar eclipses, which can be seen only in certain earth where it's nighttime, Noyes said."Millions of people will see it tonight," he said...
...lesions, known as solar or actinic keratoses, commonly appear as rough red areas on the skin. Wrinkling--technically known as photoaging--and the lesions are different abnormalities related to exposure to dangerous ultraviolet rays...
...novel properties of such materials makethem useful in solar cells and in the structuralcomponents of jet engines, Aziz says...
Most of the work of investigating and colonizing the solar system (and perhaps beyond) would be done by robot probes smaller and smarter than those of today. Advances in computer technology and genetic engineering, predicts physicist Freeman Dyson of the Institute for Advanced Study in Princeton, New Jersey, will enable scientists to squeeze the capabilities of a Voyager spacecraft, say, into a 2-lb. package that is half machine, half organism. This he dubs the astrochicken. Launched as an "egg," the astrochicken would sprout solar-panel wings that would double as radio antennae during flight. Arriving at its destination...
...atom by atom or molecule by molecule. His colleagues have already made motors smaller in diameter than a human hair. Drexler believes a bundle of nanorobots, weighing practically nothing, would be the perfect interstellar emissaries. Having arrived at a planet or asteroid around some distant star, perhaps in a solar sailship pushed to high speeds by a powerful laser beam from earth, they would go to work, antlike, building radio transmitters and other gear to report home for new instructions. They could also reproduce themselves and their ships in order to send off a new set of explorer robots...
