Swine Flu: Just the Latest Chapter in a 91-Year Pandemic Era
July 1, 2009 07:43 AM - Hadley Leggett, WIRED

The current strain of H1N1 influenza, or swine flu, has people scared because it’s a novel virus that most of the population has never been exposed to. But as a group, H1N1 viruses aren’t new. They’ve been circulating since 1918, when a new strain appeared simultaneously in pigs and humans and killed 40 to 50 million people in a single year. Over the past 91 years, the virus has jumped back and forth between humans, pigs and birds – and possibly even been resurrected from a laboratory freezer. Taking a historical view of the swine flu is critical to understanding the current pandemic, and future outbreaks, argue scientists in two perspectives published Monday in the New England Journal of Medicine.

June 21, 2009 02:43 PM - Robert Roy Britt, Live Science

If you've been waiting for the chance to get more done during the day, today, Sunday is your day, but only by a fraction of a second. Like a giant timepiece, Earth and sun are configured for the summer solstice once again. This year it happens June 21, the longest day of the year in the Northern Hemisphere. The sun will be up a fraction of a second longer than the day prior or the day after. (The length of the full day, including night, does not change, of course.)
