...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 tagging trouble...
...that doesn't mean everyone with a high calcium score is headed for a heart attack. For one thing, as we age, we tend to build up more plaque, and therefore more fat and calcium, in our arteries. Thus higher calcium numbers in young people are a more significant indicator of potential problems than they would be in the elderly. It also turns out that even two people of the same age with the same calcium scores don't necessarily have the same heart-disease risk. Like cholesterol, coronary calcium is only one of many risk factors that determine...
Seven Swords doesn't quite take a place among the classics. Hong Kong action movies once blossomed because talented directors like Tsui were paired with charismatic actors like Chow Yun-fat, who could elevate a genre picture with his mere presence. Sadly, the Hong Kong film industry has suffered a power drain in recent years, as no new performers have proved capable of filling the shoes of fleeing stars like Chow. Yen can knock out 100 bad guys without breaking into a sweat, but as the romantic lead in Swords, he makes the stolid Jet Li look like Cary Grant...
...Sinclair—reveals that Sir2 does not serve this function alone. Rather, a group of related genes—the Sir2 family—plays a major role in regulating lifespan. Sinclair said that one of the genes in the family appears to control functions such as fat metabolism and cell survival, while another controls body temperature and the efficiency with which an organism uses energy, and yet others protect against diabetes...
...know there will be another diet soon enough, whether it's The 3-Hour Diet regimen, which involves snacking, or the French Women Don't Get Fat approach, which involves eating a quick, light meal without your husband so he has time to see his mistress. Whichever diet it is, people will swear that it finally holds the solution. And they will believe it. It's part of the optimism Americans have about progress. It's the same attitude that allowed people to pour money into the Google IPO and watch Showtime TV shows. So I have to admit that...
