SARS and MERS: What’s Next?
It may be difficult to remember now, but when SARS was first recognized in February 2003, people were scared. This heretofore unknown disease was killing people—nearly 10 percent of those infected with what came to be recognized as the SARS-associated coronavirus. Before the end of the year, cases were reported in 29 countries.
"The original source of SARS was undoubtedly bats," said Julian Leibowitz, MD, PhD, a professor at the Texas A&M...
Computer bots are more like humans than you might think, having fights lasting years
New study findings are a warning to those using artificial intelligence for building autonomous vehicles, cyber security systems or for managing social media. It suggests that scientists may have to devote more attention to bots' diverse social life and their different cultures.Credit: © xb100 / Fotolia

NASA telescope reveals largest batch of Earth-size, habitable-zone planets around single star
NASA's Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water.
The discovery sets a new record for greatest number of habitable-zone planets found around a single star outside our solar system. All of these seven planets could have liquid...

From rocks in Colorado, evidence of a 'chaotic solar system'
The layer cake of sedimentary rock near Big Bend, Texas, shows the alternating layers of shale and limestone characteristic of the rock laid down at the bottom of a shallow ocean during the late Cretaceous period. The rock holds the 87 million-year-old signature of a 'resonance transition' in the orbits of Mars and Earth,...
