Computerized systems for labeling photos should save digital image uploaders a lot of time, and cause many more pictures to be found during web image searches.
Court cases increasingly deal with complex science and technical issues. And the last time some judges were in a science classroom was before Watson and Crick published the structure of DNA (or at least before the beginning of the Human Genome Project). We'll talk about bringing judges up to science speed with Franklin Zweig and Robert Bell, the chief judge of the Court of Appeals of Maryland. Zweig is the president and Bell is chairman of the board of directors of the Advanced Science and Technology Adjudication Resource, an organization devoted to training judges in science (and the product of a Congressional mandate accompanying the Human Genome Project). Then, in the Ask A Scientist segment, the Wildlife Conservation Society's Paul Calle responds to a listener query about how some animals seemingly eat just about anything without any dire consequences. And we'll take a quick trip through a batch of other questions submitted by listeners. Websites related to this episode include www.einshac.org; www.wcs.org; www.sciam.com/news; blog.sciam.com.
In this episode, journalist Leslie Sabbagh discusses the teen brain, the subject of her cover story in the August/September issue of Scientific American Mind. Geologist Kip Hodges, the director of the Arizona State University School of Earth and Space Exploration, answers a listener's question about the earth's fickle magnetic poles. Plus we'll test your knowledge about the status of Pluto and other science in the news. Websites mentioned on this episode include www.sciam.com and www.sciammind.com.
