A BLAST FROM THE PAST To find out whether human activities are changing the atmosphere, scientists took ice cores from ancient glaciers in Greenland and Antarctica. Bubbles of air trapped in the ice provided a pristine sampling of the atmosphere going back 650,000 years. The study, published last month in the Journal Science, found that the level of carbon dioxide, one of the greenhouse gases that can warm the planet, is now 27 percent higher than at any previous time. The level is even far higher now than it was in periods when the climate was much warmer and North America was largely tropical. Climatologists said the ice cores left no doubt that the burning of fossil fuels is altering the atmosphere in a substantial and unprecedented way.
FORBIDDEN VACCINE Ever year, about 500,000 women throughout the world develop cervical cancer. In the United States alone, the disease kills about 3,700 women annually. This year, scientists developed a vaccine against human papillomavirus, a sexually transmitted disease that is the primary cause of cervical cancer. The vaccine produced 100 percent immunity in the 6,000 women who received it as part of a multinational trial. As soon as the vaccine is licensed, some health officials say, it should be administered to all girls at age 12. But the Family Research Council and other social conservative groups vowed to fight that plan, even though it could virtually eliminate cervical cancer. Vaccinating girls against a sexually transmitted disease, they say, would reduce their incentive to abstain from premarital sex.
These are 2 that jumped out at me. The first I had never heard, the second shows the problem of letting too much religion into science. We could be saving lives here.
