Hints of Colonial Pollution Hidden in Andean Ice Cap

Traces of air pollution from 16th-century Spanish silver mines were discovered deep inside an ice cap in the Peruvian Andes, scientists announced today (Feb. 9). The researchers said it's the first clear evidence of man-made air pollution in South America from the time before the Industrial Revolution. Though the imprint of metal-rich smog was discovered in Peru, the pollution likely originated hundreds of miles away, in what is now Bolivia, at the Potosí mountaintop silver mines. "There is a long pre-industrial history of mining in Peru and Bolivia," said study author Paolo Gabrielli, a research scientist at the Byrd Polar and Climate Research Center at Ohio State University.

Orion Nebula Glows in Amateur Astronomer's Amazing Photo

This stunning image of the Orion Nebula shows the bright, colorful region of the celestial object. Amateur astronomer Keith Hanssen took the image in November from Montana. "I had purchased a telescope for the first time in my life earlier in 2013 after retiring and moving to Montana. In the summer of 2014 I started taking a few deep sky objects but I was always waiting for the Great Orion Nebula to return to the evening sky," Hanssen wrote in an email to Space.com.

Cheaper robots could replace more factory workers: study

The falling cost of industrial robots will allow manufacturers to use them to replace more factory workers over the next decade while lowering labor costs, according to new research. Robots now perform roughly 10 percent of manufacturing tasks that can be done by machines, according to the Boston Consulting Group. In turn, labor costs stand to drop by 16 percent on average globally over that time, according to the research. The shift will mean an increasing demand for skilled workers who can operate the machines, said Hal Sirkin, a senior partner at Boston Consulting.

America's Amazing, Drivable Crater: Alamo Impact Yields Secrets

One of America's biggest impact craters was sliced and diced until it spread across Nevada like a plate of crudités. Evidence provided by pulverized rocks suggests the crater was more than 90 miles (150 kilometers) wide, as big as the Chesapeake Bay impact crater offshore Virginia. The findings, published Jan. 14 in the journal Geosphere, offer the most comprehensive view yet of the Alamo crater, the most accessible impact crater in North America. If you drive along Nevada's Extraterrestrial Highway, you're traveling through the Alamo impact crater.

Europe's Experimental Mini-Space Shuttle to Launch Wednesday

The European Space Agency (ESA) plans to launch an experimental space plane this Wednesday to test out technologies needed for vehicles to survive the return to Earth from space. The unmanned space plane, called the Intermediate eXperimental Vehicle (IXV), is slated to blast off Wednesday (Feb. 11) at 8 a.m. EST (1300 GMT) from French Guiana. "The crucial moments will certainly be those after the blackout phase … The signal from the vehicle after this phase will be an important sign," Giorgio Tumino, ESA's project manager for IXV, told Space.com via email.

Peruvian ice cap harbors evidence of conquistadors' avarice

By Will Dunham WASHINGTON (Reuters) - After vanquishing the Inca Empire with superior weapons and a touch of treachery, the Spanish conquistadors sought to satisfy their lust for riches by forcing multitudes of native people to toil in silver mines in dire conditions that claimed many lives. Scientists on Monday described evidence of this bitter chapter of South American history preserved deep in an ice cap in the Peruvian Andes in the form of residue from the relentless clouds of metallic dust spewed from the mines starting in the 16th century.

Stress May Affect Heart Attack Recovery

Stress may play an important role in a person's ability to recover from a heart attack, a new study suggests. Researchers at Yale University found that younger and middle-age men and women who had more mental stress in their lives tended to have worse recovery one month after a heart attack than those under less stress. The data also showed that the women in the study experienced greater mental stress than the men, and the researchers said this difference might partially explain why women generally recover worse than men after heart attacks. A higher level of mental stress is known to affect blood flow in the heart and is linked with hardening of the arteries, said study researcher Xiao Xu, an assistant professor of obstetrics, gynecology and reproductive sciences at the Yale School of Medicine in New Haven, Connecticut.

Moon objects found in astronaut Neil Armstrong's closet

A treasure trove of objects that were supposed to have been left behind after the first moon landing have turned up in the closet of Neil Armstrong, the first man to step onto the lunar surface, the Smithsonian Institution has said. Armstrong died in August 2012 and his wife, Carol, found the items from the 1969 lunar landing as she was cleaning out one of his home closets in Cincinnati, Allan Needell, a space history curator at the National Air and Space Museum, wrote in a recent blog.

Glacier's Groans Can Pinpoint Iceberg Calving

New research finds that sound recordings can not only capture the timing of iceberg calving, but can also help determine whether that ice is breaking off above or below the waterline, and how it is doing so. Ultimately, just by using underwater microphones, researchers hope to be able to gauge how quickly a glacier is losing ice. "Melting glaciers contribute to global sea level rise, and this contribution is really substantial," study leader Oskar Glowacki, a researcher at the Polish Academy of Sciences' Institute of Geophysics, told Live Science. And that danger is poorly understood, Glowacki said.

Drones May Aid Bird Studies Without Ruffling Feathers

Drones have become an important tool in war, but these robotic flyers could have myriad uses off the battlefield, including as bird-watchers. "More or less everyone can have access to small drones, at least in Europe," said study co-author David Grémillet, an ecologist at France's National Center for Scientific Research in Montpellier. "Both researchers and members of the public are keen to approach birds with drones," Grémillet told Live Science. In the first study of the potential effects of these drones on birds, Grémillet and his colleagues flew small, camera-equipped, four-rotor "quadricopter" drones on more than 200 flights.

SpaceX signs deal for landing pad in Florida

By Irene Klotz CAPE CANAVERAL, Fla (Reuters) - Space Exploration Technologies will take over a mothballed rocket launch site in Florida to develop landing pads for its Falcon family of rockets, the U.S. Air Force said on Tuesday. A draft environmental assessment showed that SpaceX, as the California company is known, plans to build a primary concrete square landing pad measuring 200 by 200 foot (61 by 61 meters) and four round pads measuring 150 feet in diameter at Cape Canaveral Air Force Station's Launch Complex 13, which was used for 51 Atlas and Agena rockets between 1958 and 1978. The assessment was prepared for the Federal Aviation Administration, which oversees commercial space launches and landings in the United States,  "This is a classic combination of a highly successful launch past morphing into an equally promising future," Brig. Gen. Nina Armagno, commander of the Air Force's 45th Space Wing, said in a statement.

Europe to test spaceplane in bid for its first reusable space tech

The European Space Agency (ESA) is due to launch an experimental spaceplane from its spaceport in French Guiana on Wednesday which it hopes will pave the way towards Europe's first reusable space transportation systems. ESA's Intermediate eXperimental Vehicle (IXV), which is the size of a car, will lift off at 1300 GMT (0800 ET) aboard a rocket before splashing down in the Pacific Ocean around 100 minutes later. IXV, which ESA says cost around 150 million euros ($169 million) in design, development and related ground support, will separate from the rocket at an altitude of 320 kilometers (200 miles) and will coast up to an altitude of 450 kilometers before beginning re-entry. While Europe is well advanced in launcher technology and in orbiting systems, it is behind the United States when it comes to systems enabling a return to earth, IXV project manager Giorgio Tumino told Reuters.

An Evolving Guide to the (Unfinished) Universe (Op-Ed)

Thanks to the glacial pace of the publishing world, it would be almost another year and a half before the book hit the shelves, so I started (quietly) praying that there wouldn't be any new universe-shattering discoveries made before the book made it into print. Fortunately, for me at least, the Large Hadron Collider was taken off-line for an upgrade and some of the great space-based telescopes conveniently ran out of stuff like helium coolant and no major discoveries were made. The great joy of astronomy (and, indeed, science in general) is that some of the biggest discoveries — the real game changers that alter our perception of how the universe works — are those that we could never have anticipated in advance. At the time, the idea of a Big Crunch seemed to be a logical extension of the Big Bang.

Yoga Becoming More Popular With Kids, Adults

A growing number of kids and adults in the United States are practicing yoga, according to new results from a government survey. Over the last decade, the percentage of U.S. adults who said they practiced yoga increased from 5.1 percent in 2002 to 9.5 percent in 2012, according to the survey, which was conducted by the National Institutes of Health and the Centers for Disease Control and Prevention. Yoga among children is also on the rise: the percentage of children ages 4 to 17 who do yoga increased from 2.3 percent in 2007 to 3.1 percent in 2012, which translates to about 400,000 more kids practicing yoga. Part of the reason for the rise may be the increase in the number of yoga studios and instructors that has occurred in recent years, making yoga more accessible to a larger number of people, the researchers said.

SpaceX Dragon Capsule Leaves Space Station for Ocean Splashdown

SpaceX's robotic Dragon capsule is headed back to Earth after spending one month attached to the International Space Station, marking the start of a big day for the private spaceflight company that also includes a satellite launch and bold rocket landing attempt. The uncrewed Dragon supply ship — carrying hardware and experiments back from the station — cast off from the space station at about 2:10 p.m. EST (1910 GMT) today, Feb. 10. Dragon will splash down in the Pacific Ocean at 7:44 p.m. EST (0044 Feb. 11 GMT), where a recovery ship is standing by to retrieve the capsule. If all goes according to plan, the splashdown should occur just hours after SpaceX is due to launch a Falcon 9 rocket carrying Deep Space Climate Observatory (DSCOVR) space weather satellite into orbit.
