...long, has the equivalent of an army division patrolling it, and many Americans say it should be buttoned down even tighter. At the beginning of a new century, there may be no country on earth with as much potential as Mexico to destabilize the U.S.--and to preserve its standard of living. No wonder people can't decide how much the border should be a barrier, how much a bridge...
Here's another twist that doesn't usually get emphasized: although the data supporting the health benefits of moderate alcohol consumption are strong, they are almost entirely from epidemiological studies, not the large, randomized, placebo-controlled trials that are the gold standard of science. Epidemiological studies are very good at identifying possible trends and associations, but they are not designed to prove cause and effect. That's not necessarily a problem. No one has ever done a randomized trial of smoking, yet it clearly causes cancer. On the other hand, it was on the basis of good epidemiological evidence that...
...camera to come up with better techniques, but I would strongly suggest that they start a major hunt for some good writers who have new ideas. Harper Paul Williams Alpharetta, Georgia, U.S. Your story seemed to imply that Hollywood's reluctance to accept high-definition video as the standard for image capture is due to nostalgia or a vague notion that film just feels more organic.

Digital imaging technology will surpass film quality, and that's when moviemakers will start shooting most...

Earle is a Democrat and DeLay has attacked the charges as "a political hit job." He says he did not personally carry out the transactions and that, in any case, they are standard practice for parties around the country. Regardless, DeLay was forced to vacate his post as majority leader because of a House Republican rule (known as "the DeLay rule," because it was enacted amid concern about his legal situation) that requires a leader under indictment to step down...
...across America thinking twice about their bad habits, because the implication is that smokers and drinkers should be getting screened earlier than ever for colorectal cancer. Doctors usually recommend that patients schedule their first exam on or near their 50th birthday. If you get a colonoscopy--considered the gold standard of screenings because it allows doctors to examine the whole length of the lower intestine and snip off any precancerous polyps they find--you may not need to be screened again for 10 years. If you use one of the less definitive tests-- a flexible sigmoidoscopy, barium enema or simple...
