Indeed, Stair represents a new wave of AI, one that integrates learning, vision, navigation, manipulation, planning, reasoning, speech and natural-language processing. It also marks a transition of AI from narrow, carefully defined domains to real-world situations in which systems learn to deal with complex data and adapt to uncertainty.

"People have imagined that if we stopped emitting carbon dioxide that the climate would go back to normal in 100 years or 200 years. What we're showing here is that's not right. It's essentially an irreversible change that will last for more than a thousand years," Solomon says.

Harrison, of Swarthmore College, and Anderson, of The Living Tongues Institute, are the stars of Ironbound Films’ The Linguists—an exciting and edifying documentary that follows their quest to document (and save) some of the world’s many endangered languages. GOOD phoned these two intrepid linguists to hear their takes on the importance of language revitalization, the value of intellectual diversity, and the sometimes humbling experience of adventure science.

Our Internet Health Pilot site provides links to hundreds of reliable health sites. Our Casewatch site contains a large library of legal cases, licensing board actions, government sanctions, and regulatory actions against questionable medical products.

Even the insect's inedible silk, which makes up 50% of the weight of the dry cocoon, could provide nutrients: The material can be rendered edible through chemical processing and can be mixed with fruit juice, sugar, and food coloring to produce jam, the researchers reported.

Even moderate amounts of the stimulant can lead people to hear voices and see things that are not there, the researchers warn.

Previous studies have shown that too much caffeine can lead to heart palpitations, insomnia and even affect a woman's chances of becoming pregnant.

Dr. Behar and his colleagues at the University of Colorado this past August released 90 yellow rubber ducks into the melt water flowing down a chasm in the largest of Greenland's 200 glaciers -- the Jakobshavn Isbrae -- which has been thinning rapidly since 1997. Each duck was imprinted with an email address and, in three languages, the offer of a reward. If all goes well, Dr. Behar hopes that one day they will emerge 30 miles or so away at the glacier's edge in the open water of Disko Bay near Ilulissat, bobbing brightly amid the icebergs north of the Arctic Circle, each one a significant clue to just how warming temperatures may speed the glacier's slide to the sea.

The Schwarzschild geometry describes the spacetime geometry of empty space surrounding any spherical mass. Karl Schwarzschild derived this geometry at the close of 1915, within a few weeks of Albert Einstein publishing his fundamental paper on the Theory of General Relativity.

Our universe is perfectly tailored for life. That may be the work of God or the result of our universe being one of many.

It turns out that if you peel the popular adhesive tape off its roll in a vacuum chamber, it emits X-rays.
