A cemetery dating back roughly 1,700 years has been discovered along part of the Silk Road, a series of ancient trade routes that once connected China to the Roman Empire. The cemetery was found in the city of Kucha, which is located in present-day northwest China.

A DNA test has confirmed that a lone gray wolf is roaming Arizona, just north of the Grand Canyon, a long way from its home in the northern Rockies. The animal, which is protected under the Endangered Species Act, is the first known gray wolf to visit Arizona in about 70 years. After repeated sightings of the wolf over the last month, the U.S. Fish and Wildlife Service (FWS) collected a sample of the animal's feces in Kaibab National Forest, near the north rim of the Grand Canyon. This means the wolf traveled at least 450 miles (725 kilometers) to get to northern Arizona.

Antarctica's ice paradox has yet another puzzling layer. Not only is the amount of sea ice increasing each year, but an underwater robot now shows the ice is also much thicker than was previously thought, a new study reports. According to climate models, the region's sea ice should be shrinking each year because of global warming. Instead, satellite observations show the ice is expanding, and the continent's sea ice has set new records for the past three winters.

By Patricia Reaney NEW YORK (Reuters) - A Nobel Prize gold medal awarded to American scientist Dr. James Watson, a co-discoverer of DNA, is expected to sell for up to $3.5 million at auction next month in New York, Christie's said on Monday. Watson, along with Francis Crick and Maurice Wilkins, unraveled the double-helix structure and function of deoxyribonucleic acid (DNA) in England in 1953 in a discovery that heralded the modern era of biology. The medal, the first to be offered by a living recipient, will go under the hammer on Dec. 4, with a pre-sale estimate of $2.5 million to $3. ...

NASA's Cassini spacecraft captured this intimate snapshot of Saturn on Aug. 23 while flying about 1.1 million miles (1.7 million kilometers) from the ringed planet, though the space agency unveiled the image on Monday (Nov. 17) as an image feature. The conditions in Saturn's atmosphere have created some unique formations, like a hexagon-shaped cloud. The spacecraft was positioned on the sunlit side of Saturn's rings, which serve as a backdrop and about 25 degrees above the plane of the rings. The image was taken in red light with the Cassini spacecraft's narrow-angle camera.

NASA astronaut Terry Virts, European Space Agency astronaut Samantha Cristoforetti and cosmonaut Anton Shkaplerov blasted off atop a Russian Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan at 4:01 p.m. EST (2101 GMT, 3:01 a.m. local time in Baikonur). The trio reached the space station about six hours later after a quick trip through space. Virts is planning on sharing his experiences in space via social media websites like Twitter.

By Irene Klotz (Reuters) - A Russian Soyuz rocket blasted off from the Baikonur Cosmodrome in Kazahkstan on Sunday to deliver three new crew members to the International Space Station, including Italy's first female astronaut. A Soyuz capsule carrying incoming station commander Terry Virts from U.S. space agency NASA, Soyuz commander Anton Shkaplerov from the Russian Federal Space Agency and first-time flier Samantha Cristoforetti of the European Space Agency lifted off at 2101 GMT (4.01 p.m. EST) Sunday. ...

By Kate Kelland LONDON (Reuters) - - A banking culture that implicitly puts financial gain above all else fuels greed and dishonesty and makes bankers more likely to cheat, according to the findings of a scientific study. Researchers in Switzerland studied bank workers and other professionals in experiments in which they won more money if they cheated, and found that bankers were more dishonest when they were made particularly aware of their professional role. ...

Small volcanic eruptions account for part of the global warming slowdown since 2000, a new study suggests. Until now, the climate impacts of small volcanic blasts were overlooked because their planet-cooling particles cluster below the reach of satellites, scientists reported Oct. 31 in the journal Geophysical Research Letters. The stratosphere is the second layer of Earth's atmosphere, above the one in which humans live (the troposphere). Closer to the polar regions, the boundary drops to about 6 miles (10 km), said lead study author David Ridley, an atmospheric scientist at MIT.

JOHANNESBURG (Reuters) - A tiny shrimp equipped with large, candy-striped eyes to ward off predators has been discovered in South African waters, the University of Cape Town said on Friday. The 10-15 mm-long crustacean has been christened the "star-gazer mysid" as its eyes seem to gaze permanently upwards. Similar to insects' eyes, they each look in a different direction. "The vivid ringed patterns are thought to be there to make the eyes appear to belong to a much bigger creature, and hence to scare off predators," the university said. ...
