SpaceX capsule splashes down in Pacific with space station cargo
News ImageBy Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - A Space Exploration Technologies Dragon cargo capsule made a parachute splashdown into the Pacific Ocean on Thursday, wrapping up a five-week stay at the International Space Station. The capsule blasted off on April 14 aboard a Falcon 9 rocket from Cape Canaveral Air Force Station in Florida and arrived at the orbiting outpost three days later with more than 4,300 pounds (1,950 kg) of food, supplies and science experiments for the live-aboard crew. It was repacked with 3,100 pounds of science samples and other equipment and released back into orbit at 7:04 a.m. EDT (1104 GMT) on Thursday for a return trip to Earth, a NASA TV broadcast showed.

Bowwow wow! Dog domestication much older than previously known
News ImageBy Will Dunham WASHINGTON (Reuters) - Genetic information from a 35,000-year-old wolf bone found below a frozen cliff in Siberia is shedding new light on humankind's long relationship with dogs, showing canine domestication may have occurred earlier than previously thought. Scientists said on Thursday they pieced together the genome of the wolf that lived on Russia's Taimyr Peninsula and found that it belonged to a population that likely represented the most recent common ancestor between dogs and wolves. Using this genetic information, they estimated that dog domestication occurred between 27,000 and 40,000 years ago.

Scientists want you to know plankton is not just whale food
News ImageBy Will Dunham WASHINGTON (Reuters) - Scientists on Thursday unveiled the most comprehensive analysis ever undertaken of the world's ocean plankton, the tiny organisms that serve as food for marine creatures such as the blue whale, but also provide half the oxygen we breathe. Planktonincludemicroscopic plants and animals, fish larvae, bacteria, viruses and other microorganisms that drift in the oceans. "Plankton are much more than just food for the whales," said Chris Bowler, a research director at France's National Center for Scientific Research, and one of the scientists involved in the study published in the journal Science.

Lockheed-Boeing rocket venture needs commercial orders to survive
By Andrea Shalal WASHINGTON (Reuters) - United Launch Alliance, a 50-50 joint venture of Lockheed Martin Corp and Boeing Co, on Thursday said it would go out of business unless it won commercial and civil satellite launch orders to offset an expected slump in U.S. military and spy launches. ULA President Tory Bruno said the company must attract those kind of orders to remain a "viable economic entity" so it is scrambling to restructure and develop a new rocket that in seven or eight years could launch satellites twice as fast at half the current cost. Formed by the two largest U.S. weapons makers in 2006, ULA has long been the sole company able to launch U.S. military and intelligence satellites into orbit. Thu, 21 May 2015 16:54:16 -0400
Mind-controlled prosthetic limbs allow precise, smooth movement
News ImageBy Will Dunham WASHINGTON (Reuters) - More than a decade after becoming paralyzed from the neck down, Erik Sorto has been unable to perform even the simplest of daily tasks. "That was the ultimate goal: to drink a beer by myself," said Sorto, a 34-year-old from Los Angeles who became a quadriplegic after a 2002 gunshot wound. Things may be looking up for Sorto and others with similar disabilities.

Memorial Day Meals: Expert Tips for Packing a Healthy Picnic
Memorial Day is considered the unofficial start of summer and perhaps the unofficial start of the outdoor eating season. Picnics are appealing, especially to people in colder climates who don't get many chances to eat outside in nice weather and enjoy a slow, relaxing meal, and they could also bring back childhood memories, said Sara Haas, a dietitian and chef in Chicago and a spokeswoman for the Academy of Nutrition and Dietetics. So pack up the red-checkered tablecloth, coolers and picnic basket, and bring along family and friends. Sat, 23 May 2015 14:49:18 -0400
Squid 'Sees' with Its Skin (No Eyes Needed)
Squid, cuttlefish and octopuses are masters of camouflage, capable of changing their skin colors and patterns in the blink of an eye. Two new studies, published this week in the Journal of Experimental Biology, find that cephalopod skin is chock-full of light-sensing cells typically found in eyes that help them "see." The cells likely send signals to alter skin coloration without involving the central nervous system, the researchers said. "It may be that the patterning is just generated directly on the spot, just by the cells," said Tom Cronin, a biologist at the University of Maryland and an author of one of the studies.

Record-Breaking Energy Unleashed in Largest Atom Smasher
News ImageThe world's largest atom smasher is really cranking now: Protons zipped around the giant underground ring at near light-speed and collided head on, releasing record-breaking energies. The beauty of the fallout from these powerful particle smash-ups can be seen in images released yesterday (May 21) by the European Organization for Nuclear Research (CERN), which oversees the 17-mile-long (27 kilometers) Large Hadron Collider (LHC). This week during a test run, the protons sped into each other with energies of 13 tera-electronvolts (TeV), or double the collider's previous power.

See Jupiter and the Moon in Night Sky Spectacle Tonight
News ImageThere, about half way up from the south-southwest horizon to the overhead point, youll see an eye-catching sight for the Memorial Day weekend: Jupiter and the moon in a celestial display. Tonight, a rather wide crescent moon, 34-percent illuminated will be visible against the darkening sky and hovering about 3 degrees almost directly above this lunar sliver will be a brilliant silvery white "star." But this isn't a star, but the planet identified with the supreme sky-god, Jupiter. To judge how far apart Jupiter and the moon will appear in the sky, remember that your clenched fist, correctly held, will measure 10 degrees of the night sky.

What Are Those Bright Spots on Ceres? Go Vote!
News ImageThe puzzling white spots on the surface of the dwarf planet Ceres are definitely reflecting sunlight, scientists said, but the cause of the marks remains a mystery. The newest batch of images from the Dawn spacecraft, which began orbiting Ceres on March 6, was released May 15. With the release of these new images, NASA has asked the public to submit a guess for what is creating the spots: volcanos, geysers, rocks, ice, salt deposits, or "other." As of this writing, 37 percent of people who took NASA's poll for what the white spots might be said "other." Alien colonies, perhaps?

Ancient Wolf DNA Could Solve Dog Origin Mystery
News ImageGenetic evidence from an ancient wolf bone discovered lying on the tundra in Siberia's Taimyr Peninsula reveals that wolves and dogs split from their common ancestor at least 27,000 years ago. "Although separation isn't the same as domestication, this opens up the possibility that domestication occurred much earlier than we thought before," said lead study author Pontus Skoglund, who studies ancient DNA at Harvard Medical School and the Broad Institute in Massachusetts. "Siberian huskies have a portion of their genome that traces back exclusively to this ancient Siberian wolf," Skoglund told Live Science.
