- Science Podcast: 10 May Show
Listen to stories on markets and morality, origins for cirrus clouds, capturing an asteroid, and more.
Products & Materials
- New Products
A weekly roundup of information on newly offered instrumentation, apparatus, and laboratory materials of potential interest to researchers.
News of the Week
- Around the World
In science news around the world, the Large Millimeter Telescope will begin its first scientific observation season next week, journals are being asked to help tighten U.S. trade sanctions on Iran, and a new research challenge seeks studies that reveal differences between males and females in the development of Alzheimer's disease.
- Newsmakers
Science speaks with microbiologist George F. Gao, who is in the trenches of the H7N9 avian influenza outbreak that has killed 27 people in China since March. And after 26 years, Eugenie Scott, the founding executive director of the National Center for Science Education, has announced her retirement.
- Random Sample
When settlers in the Jamestown, Virginia, colony ran out of food in the winter of 1609, some contemporary records suggest they resorted to eating each other. Now, scientists have found the first physical evidence that they did. And rumors surrounding a bizarre 6-inch-long skeleton have been put to rest with scientists confirming that the specimen is human.
