...world is a brighter place because Shuji Nakamura is not easily discouraged. In 1993 he astonished the scientific community with the first successful blue light-emitting diode, or LED. The blue LED was the last step in the creation of lighting's holy grail, the brilliant white LED--an ultra-efficient successor to Thomas Edison's incandescent lightbulb, circa...
...than the grim reaping of wartime and he does not blink at showing them. They are, in fact, the most shocking and subversive and hard to accept of all his images. We didn't want to see people we've always thought of as heroes in an anti-heroic light. And now we don't want to see people we think of as noble victims turn into ignoble victimizers...
...discovery of REM sleep was supposed to be an opening through which science could throw light on dreaming. And it was, up to a point. But it has also been an obstacle to progress. What happened was that many scientists became convinced that REM sleep and dreaming are more or less the same thing-that they're underpinned by the same physiological processes. REM became known as "dreaming sleep," but that is almost certainly an oversimplification. "Sadly, there's an authoritative school of thought that will not let go of this idea," says Mark Solms, professor of neuropsychology...
...President Bush, however, has promised to veto the bill, delivering his usual warnings about undermining our soldiers, breaking promises to the Iraqi people, and the possibility of winning the war. We understand the Congressional Democrats’ frustration—the only way to make Bush see the light seems to be to force him to do so through legislation.

The recall brought to light that the wheat gluten, which was eventually recalled, came from a single Chinese company but ended up in over 100 brands of pet food. ChemNutra Inc., based in Las Vegas, bought 873 tons of gluten from the Chinese company, farmed it out to three pet food makers and one distributor that services the industry. A highly centralized process may be cheap...
