...waters come down, they will expose a city that will have been steeping for weeks in a noxious soup. Although emergency-management officials are relieved that the flooding did not crack open the storage tanks of the large petrochemical factories south and east of the city, the waters still contain a poisonous mix of gasoline, household and industrial chemicals and stinking human waste. They will leave a layer of heavily contaminated silt everywhere. John Pardue, director of the Louisiana Water Resources Research Institute at Louisiana State University, says, "We're going to have to find out how deep the contamination...
...from as far afield as Singapore and Estonia compete for the world title. Scandinavians have held the top spot in recent years (in 2004, Oslo chef Ola Nilsson unseated the previous year's Swedish winner). The trick is to combine speed with precision. Competitors are penalized if their oysters contain grit, or if flesh is improperly detached from the shells or damaged...
...least that's the idea. Cardiac CT is not foolproof. Unlike catheterization, it doesn't yet produce clear enough pictures of some of the smaller arteries of the heart. And any arterial plaques that contain calcium deposits, which typically appear in older people, show up like white blobs, so that the blockage could be partial or total (see box). Then there's the issue of radiation. A typical cardiac CT scan exposes a patient to 50 to 80 times the amount of radiation in a series of full-mouth dental X rays. Researchers hope to figure out ways to decrease...
Even the sharpest pictures can't show you everything. Over the past few years, it has become increasingly clear that not all plaques that form inside a coronary artery's walls are dangerous. Some appear to be stable and don't grow much, whereas others contain an explosive combination of hardened fat and inflammatory proteins that make them likely to burst, triggering a heart attack. Neither CT nor MRI scans can reliably distinguish between the two sorts of lesions. Researchers are developing compounds that are chemically attracted to the inflammatory components of an unstable plaque with the hope of someday...
...country, Las Vegas has a powerful thirst. Every month 5,000 to 7,000 newcomers arrive to retire or find jobs, meaning the already swollen population could double in 20 to 30 years. Though water-conservation measures have reduced the city's annual consumption since 2002, they cannot contain such explosive growth. So Las Vegas has gone looking for its water farther from home...
