...inch long by an inch and a half, maybe two inches wide, all the flesh. It severed the main tendon to his big toe, the main tendon to the next toe, crushed the casing to the joints that join the big toe to the foot. So its bacteria was then inside the bone. This thing carries 22 deadly bacteria in its mouth. His toe was completely hanging off, and we didn't know if he would keep his toe, his foot, if he would ever be able to walk again or what was gonna happen. There were tons of children...
...scientists reported at last week's meeting of the American Society for Microbiology. In a preliminary study--financed by the tea industry--volunteers swished either black tea or lukewarm water in their mouth. An analysis of their saliva showed that tea inhibits the growth of tooth-decaying bacteria and reduces their tendency to form sticky clumps. In addition, tea drinkers' saliva contains less enamel-eroding acid. Does that translate into fewer cavities? Probably. In previous clinical trials, green tea was shown to prevent cavities, and these new findings lead researchers to suspect that black tea will too--as long...
...astronomical sums of other people's money or just deciding what to pack for London. It might seem another problem altogether to spend your time reconstructing that fateful period 3.5 billion years ago, when protein molecules dancing through the earth's primordial foam collectively spit forth the first proto-bacteria, life's earliest ancestors. You know the rest...
...mercury being dumped by the illegal miners in Talawaan is a relatively stable compound that is toxic only after repeated contact. But eventually it will be converted by bacteria into methyl mercury, the far more toxic form that wreaked such damage in Minamata after the same transformation took place. Guesses about how long the process will take range from two to 10 years. But nobody disputes that the conversion will happen. And when it does, Manado will be in grave danger. In Minamata, the population subsisted largely on a diet of fish caught in their...
...quit smoking? Here's a new one: to protect your kids' teeth. It turns out that secondhand smoke can nearly double the risk that kids ages 4 through 11 will develop cavities. What's the connection? A by-product of nicotine called cotinine, once thought to kill off the bacteria linked to cavities, actually does the opposite, encouraging tooth-destroying bugs to grow and multiply...
