New avian flu viruses send U.S. scientists scrambling

By Julie Steenhuysen CHICAGO (Reuters) - Three highly pathogenic avian flu viruses that have infected poultry and wild birds in the U.S. Midwest appear unlikely to present a significant risk to humans. The H parts, which are highly pathogenic in poultry, originated in Asia, and the N parts come from North American, low pathogenic, avian flu viruses, said Dr. Rubin Donis, an associate director fo

Giant Easter Island 'Hats' Rolled Into Place, Study Says

The distinctive headgear worn by some of the famous Easter Island statues may have been rolled up ramps to reach those high perches, a new study suggests. A simple analysis of the physics suggests that rolling the headwear — bulky cylindrical shapes that look like Russian fur hats — would have been a relatively easy matter, said study co-author Sean Hixon, an undergraduate student in archaeology a

Whooping Cough Outbreaks Traced to Change in Vaccine

The recent outbreaks of whooping cough in the United States may be due, in part, to a change made two decades ago to vaccine ingredients, a new study finds. In 2012, the United States had about 48,000 cases of whooping cough (also called pertussis) — the most cases since 1955. They used an enormous data set from a variety of sources on whooping cough cases in the U.S. from 1950 to 2009. They fou
