...abrupt and fatal loss of heart function - is estimated to kill anywhere from 1 in 15,000 to 1 in 50,000 athletes. According to the International Olympic Committee, that rate is about three times higher than in the normal population. The condition usually gains public attention only after the death of an élite sportsman, like when Reggie Lewis of the Boston Celtics collapsed and died during basketball practice in 1993. However, all participants in regular athletic training - from recreational joggers to high school soccer players - are at increased risk. Almost all cases of SCD occur in athletes with...
...whether there was something wrong with their hearts. What's more, some cardiologists believe that physical examinations can be equally effective in uncovering heart defects in athletes. A non-ECG screening of high school and college athletes in the U.S. from 1983 to 1993 resulted in an annual death rate as low as in the Italian ECG screening program - although some cardiologists have disputed the methodology of the study that examined the U.S. screening program.

While the sheer number and size of the found animals were extraordinary - and made possible because the volcanic crater's ecology had been virtually undisturbed by humans - the scientific discovery of new species is actually quite routine. In fact, biologists are identifying new species at a torrid rate, about 50 a day; nearly 17,000 new plants and animals were described in 2006 alone, or some 1% of the 1.8 million species that have been recognized so far. (See 10 species near extinction...
...even as we discover new species, the existing ones are coming under increasing threat. We're losing species 10,000 times faster than the natural rate, a loss of life so great that we've entered the sixth great mass extinction in Earth's history. Why? Global warming plays a role. When the environment changes faster than animals and plants can adapt, extinction is inevitable. By one estimate, more than one-third of all land plants and animals could be extinguished by 2050 if climate change continues unabated. (See pictures of India's contraband wildlife...
...tutoring fees haven’t gone up in more than a decade, raising tutors’ prices seems a sensible move. Therefore, we support the BSC’s decision to save money in a way that will not diminish the services it provides by upping its tuition rates from $4 to $7 per hour (while the rate increases to $14 per hour after the first 10 hours, apparently fewer than a quarter of tutoring requests fall into this category). Critical to our support of the increase, however, is the continued role of the Financial Aid Office, which will...
