...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...
...government cover-up, bloggers seized on documents leaked last week from an investigation into how London police came to shoot an innocent Brazilian seven times in the head a day after the attempted bombings on July 21. Contrary to initial accounts, Jean Charles de Menezes did not appear to have worn a bulky jacket or vaulted a turnstile. "We figured the police lied from Day One," crowed WIS[S]E WORDS. But a former British army officer pointed out on the CABARFEIDH pages that the police had said "very little regarding the entire horrific episode." That includes failing to counter...
Intelligence agencies say Tehran still funds various political parties in Iraq. Documents from Iranian Revolutionary Guard Corps files obtained by TIME include voluminous pay records from August 2004 that appear to indicate that Iran was paying the salaries of at least 11,740 members of the Badr Corps. British and U.S. military intelligence suspect those salaries are still being paid, although Badr leader Hadi al-Amri denies that. "I've told the American officers to bring us the evidence that we have a deal with Iran, and we will be ready, but they say they don't have...
Western diplomats say that so far, the ayatullahs appear to be acting defensively rather than offensively. An encouraging sign is that even Shi'ite beneficiaries of Tehran exhibit strains of Iraqi and Arab nationalism; and many have strong familial and tribal ties with the Sunnis. "We are sons of Iraq. The circumstances that forced me to leave did not change my identity," says Badr leader al-Amri. He's proud of his cooperation with the Revolutionary Guard to battle Saddam but says it extended only "to the limit of our interests." An informed Western observer thinks that while those groups...
