NASA Probe Snaps Amazing New Views of Dwarf Planet Ceres (Photos, Video)

	NASA Probe Snaps Amazing New Views of Dwarf Planet Ceres (Photos, Video) A spacecraft closing in on the dwarf planet Ceres in the solar system's asteroid belt has captured tantalizing new views of the huge space rock, revealing hints of craters and other structures on the surface of this mysterious body. NASA's Dawn spacecraft snapped the new images of Ceres, which is the largest object in the asteroid belt between the orbits of Mars and Jupiter, on Jan. 13. Dawn is rapidly approaching Ceres and is due to arrive in orbit around the dwarf planet on March 6. "The [Dawn] team is very excited to examine the surface of Ceres in never-before-seen detail," Chris Russell, principal investigator for the Dawn mission, said in a statement from NASA's Jet Propulsion Laboratory in Pasadena, California.

People in the study who drank four or more cups of coffee daily were 20 percent less likely to develop malignant melanoma than noncoffee drinkers, according to the study published today (Jan. 20) in JNCI: Journal of the National Cancer Institute. Of course, the findings don't give you license to fire up the Mr. Coffee and then spend your day lounging in the sun without any sunscreen — the best way to prevent skin cancer remains avoiding sun exposure and ultraviolet radiation, said study researcher Erikka Loftfield, a doctoral student at the Yale School of Public Health and a fellow at the National Cancer Institute. Previous studies had found hints that drinking coffee might be linked to lower rates of nonmelanoma skin cancers, but the findings were mixed when researchers looked at coffee and melanoma, the deadliest form of skin cancer.

Musk first revealed the idea for this "fifth mode of transportation" (i.e., not a car, train, plane or boat) in August 2013. But during a speech at the Texas Transportation Forum on last week, Musk said he is planning to build a 5-mile (8 kilometers) track to test prototype versions of the pods that could one day travel the Hyperloop at speeds of up to 760 mph (1,220 km/h). Musk says the Hyperloop is a great solution for traveling between congested cities that aren't very far apart (no farther than 900 miles, or 1,450 kilometers apart, to be exact).

Google and Fidelity will collectively own just under 10 percent of SpaceX, the company said in a statement on Tuesday. (Reporting by Avik Das in Bengaluru; Editing by Savio D'Souza) Read More » Elon Musk's SpaceX Gets $1 Billion from Google and Fidelity Google and Fidelity Investments have invested $1 billion in SpaceX, representatives of the private spaceflight company announced today (Jan. 20). Google and Fidelity now together own about 10 percent of SpaceX, which is run by billionaire entrepreneur Elon Musk. Other SpaceX investors are Founders Fund, Draper Fisher Jurvetson, Valor Equity Partners and Capricorn, company representatives said. The cash infusion could help SpaceX — which to date has made its name with rockets and a spaceship called Dragon — get its bold new satellite program off the ground.

The 20-story-tall rocket, manufactured and flown by United Launch Alliance, a joint venture of Lockheed Martin Corp and Boeing Co, lifted off at 8:04 p.m. EST, the first of 13 missions the company plans for this year. Perched on top of the rocket was the third spacecraft for the U.S. Navy's $7.3 billion Mobile User Objective System, or MUOS, network, which is intended to provide 3G-like cellular technology to vehicles, ships, submarines, aircraft and troops on the move. "MUOS is a game-changer in communications for our warfighters," Iris Bombelyn of satellite manufacturer Lockheed Martin said in a statement before launch.

Obama urged Congress in his address to boost research funding to support new investments in "precision medicine." "I want the country that eliminated polio and mapped the human genome to lead a new era of medicine – one that delivers the right treatment at the right time," Obama said, noting the approach had helped reverse cystic fibrosis in some patients. "Tonight, I'm launching a new precision medicine initiative to bring us closer to curing diseases like cancer and diabetes – and to give all of us access to the personalized information we need to keep ourselves and our families healthier." The sequencing of individual genomes, read-outs of a person's complete genetic information, could speed scientific research and help drug companies and physicians tailor medicines to an individual's genetic profile.

Instead of there being some kind of multicellular organism on, say, Jupiter's moon Europa, scientists instead aim to find something more like a microbe. Frank Rosenzweig, an evolutionary geneticist at the University of Montana, is looking into such questions over the next five years with funding from the NASA Astrobiology Institute. "Over my career, I've been interested in what are the genetic bases of adaptation and how do complex communities evolve from single clones," Rosenzweig said. Complex life is only known to exist on Earth, but scientists aren't ruling out other locations in the Solar System.

Two new maps released Friday (Jan. 16) considerably improve estimates of the amount of land farmed in the world — one map reveals the world's agricultural lands to a resolution of 1 kilometer, and the other  provides the first look at the sizes of the fields being used for agriculture, the researchers said. "The field-size map is really unique — no such global product currently exists," study co-author Linda See, a researcher at the International Institute for Applied Systems Analysis in Austria, said in a statement. The researchers built the cropland database by combining information from several sources, such as satellite images, regional maps, video and geotagged photos, which were shared with them by groups around the world.

The castle dates back to the 15th century, and once housed the powerful MacQuillan family, which controlled a large amount of territory in Northern Ireland. On a recent dig, the Northern Ireland Environment Agency planned to uncover part of the lost 17th century town of Dunluce near the castle. "This is a tremendously exciting historical development," Mark Durkan, Northern Ireland's environment minister, said in a statement.

The increasing use of opioids to treat people with chronic pain has created serious concerns about misuse and addiction in the medical community. Now, a panel convened by the National Institutes of Health has taken a deep look at the data, finding that in the absence of solid evidence on the effectiveness of opioids, many doctors prescribe doses of the painkillers that are too high. On the other hand, some doctors avoid prescribing opioids altogether, out of fear of sending patients down a path to addiction.

Run by the British technology firm Satellite Applications Catapult and backed by environmental groups, Project 'Eyes on the Sea' will open a "Virtual War Room". Experts will be able to watch satellite feeds of the waters around Easter Island, a Chilean territory in the southeastern Pacific Ocean, and the western Pacific island nation of Palau, which lacks the resources to monitor all the illegal fishing taking place near its waters. The technology analyses numerous sources of live satellite tracking data, enabling monitors to link to information about a ship's country of registration and ownership history to spot suspicious vessels. "This system will enable authorities to share information on those vessels operating outside the law, build a comprehensive case against them, track them into port or within reach of enforcement vessels, and take action against them," Joshua Reichert from the Pew Charitable Trusts, the environmental group driving the project, said in a statement. Read More » Mummy Mask May Reveal Oldest Known Gospel A text that may be the oldest copy of a gospel known to exist — a fragment of the Gospel of Mark that was written during the first century, before the year 90 — is set to be published. In recent years scientists have developed a technique that allows the glue of mummy masks to be undone without harming the ink on the paper. The first-century gospel is one of hundreds of new texts that a team of about three-dozen scientists and scholars is working to uncover, and analyze, by using this technique of ungluing the masks, said Craig Evans, a professor of New Testament studies at Acadia Divinity College in Wolfville, Nova Scotia. Not just Christian documents, not just biblical documents, but classical Greek texts, business papers, various mundane papers, personal letters," Evans told Live Science.

But the research raises a number of ethical questions, including whether it is acceptable to use human fetal organs in research, or to transplant human organs into animals. Previously, other scientists had attempted to grow immature human kidneys in the abdomens of mice, but the new research "is definitely the first time an actual whole human organ has been grown in an animal, and has sustained the life of that animal," Gu told Live Science. In the new study, Gu and his colleagues obtained human fetal kidneys from Stem Express, a Placerville, California-based company that supplies researchers with tissue from deceased adults and fetuses.

A new study from Seattle suggests people are paying attention to calorie postings — the percentage of people in the area who said they used the calorie information on restaurant menus tripled in the years after the labels became mandatory in the region. Researchers analyzed information from more than 3,000 people living in King County, Washington, (which includes Seattle), an area that in January 2009, started to require chain restaurants to post calorie information on their menus.

The advance, reported on Wednesday in Nature, offers what one scientist calls a "genetic firewall" to achieve biocontainment, a means of insuring that GMOs cannot live outside a lab or other confined environment. Although the two labs accomplished this in bacteria, "there is no fundamental barrier" to applying the technique to plants and animals, Harvard Medical School biologist George Church, who led one of the studies, told reporters.

The clock is a visual metaphor that was created nearly 70 years ago by The Bulletin of the Atomic Scientists. Each year, the magazine's board assesses threats to humanity — with special attention to nuclear warheads and climate change — to decide whether the Doomsday Clock needs an adjustment. Tomorrow (Jan. 22), at a news conference in Washington, D.C., The Bulletin of the Atomic Scientists will announce where the hands will rest for 2015. Read More »

Food diversity under siege from global warming, UN says

	Pizza Prescription: Kids Should Eat Less, Researchers Say Children consume an average of 136 calories per day from pizza, the new study found. For the new study, Powel and her colleagues looked at questionnaires about the diets of children and teens ages 2 to 19, that were completed every two years between 2003 and 2010. The researchers found that the number of calories children consumed from pizza decreased 25 percent between 2003 and 2010, which is good news, they said. On such days, teens consume an average of 230 extra calories, and younger children consume an average of 84 extra calories, compared with the days on which kids don't eat pizza.

The results reveal that the meteorite contained a number of features associated with minerals such as olivines, phyllosilicates, carbonates, and possibly pyroxenes, as well as organics. However, a key conclusion of the paper, and one that is likely to be of keen interest to astrobiologists, is confirmation that meteorites can become contaminated by Earth-based organics very quickly. Several fragments of the meteorite were recovered, four of them shortly after the fall, and others several days later after a heavy rainstorm.  The research team used infrared spectroscopy, employing several different analytical devices to obtain spectra from very small samples.

Certain wild crops - varieties not often cultivated by today's farmers - could prove more resilient to a warming planet than some popular crop breeds, the U.N. Food and Agriculture Organisation (FAO) said. Ensuring food security and protecting at-risk species in the face of climate change is one of "the most daunting challenges facing humankind", the paper said. Between 16 and 22 percent of wild crop species may be in danger of extinction within the next 50 years, said the FAO paper.

Solar Plane's Route for Around-the-World Flight Revealed

	Big data tops humans at picking 'significant' films: study By Sharon Begley NEW YORK (Reuters) - In the escalating battle of big data vs. human experts, score another win for numbers. The most accurate predictions of which movies the U.S. Library of Congress will deem "culturally, historically, or aesthetically significant" are not the views of critics or fans but a simple algorithm applied to a database, according to a study published on Monday. The crucial data, scientists reported in Proceedings of the National Academy of Sciences, are what the Internet Movie Database (IMDb.com) calls "Connections" - films, television episodes and other works that allude to an earlier movie. For 15,425 films in IMDB.com examined in the study, the measure that was most predictive of which made it into the Library of Congress's National Film Registry, which honors "significant" movies, was the number of references to it by other films released many years later.

"Trying to describe this ancient Greek drinking game, kottabos, to my students was always a little bit difficult because we do have these illustrations of it, but they only show one part of the game — where individuals are about to flick some dregs at a target," said Heather Sharpe, an associate professor of art history at West Chester University of Pennsylvania. So, with a 3D-printed drinking cup, some diluted grape juice and a handful of willing students, Sharpe did just that.

"Our study didn't address the reasons for success," Wardle told Live Science. The men and women were participants in a long-term study on aging, and they regularly completed questionnaires about their health behaviors for up to a four-year period. The researchers looked at the effect of one partner's decision to make a positive change in one of three health behaviors — smoking, exercising or losing 5 percent of their body weight — on the other partner's health habits.

The Next-Generation Transit Survey (NGTS for short) — located at the European Southern Observatory's (ESO) Paranal Observatory — is designed to seek out planets two to eight times the diameter of Earth as they pass in front of their stars. "We are excited to begin our search for small planets around nearby stars," Peter Wheatley, an NGTS project lead from the University of Warwick, U.K., said in as statement. The NGTS is made up of 12 telescopes that will operate robotically, according to ESO.

Another printer uses a combination of conductive inks and filaments to print quadcopters already embedded with the electronics that allow them to hover in the air. The message these companies are sending couldn't be clearer: 3D printing isn't just for makers anymore. Increasingly, this trendy technology is turning into a must-have tool for doctors, researchers and engineers, according to Nick Liverman, CEO and founder of Old World Labs (OWL), a Virginia-based company that designs dissolvable 3D-printed implants.

"For seismologists, the focus was, 'If a train is passing, let's make sure we can remove those trains,'" said Nima Riahi, a researcher and seismologist at the Scripps Institution of Oceanography in La Jolla, California. Now, scientists are returning to the city, tapping into the weak signals from trains, planes, cars and other human noise as a cheap alternative to more expensive surveying techniques, according to research presented last month (December 2014) at the American Geophysical Union's annual meeting in San Francisco. "This technology is still in its infancy, but the initial results are very promising," said Larry Brown, a seismologist at Cornell University in Ithaca, New York.

By analyzing the genes of Neanderthals and other extinct human ancestors, scientists also found that modern humans may be much better at digesting starch than any other known member of the human family tree. Although modern humans are the world's only surviving human lineage, other human lineages also once dwelled on Earth. These included Neanderthals, the closest extinct relatives to modern humans and Denisovans, whose genetic footprint apparently extended across Asia.

"Recess is a pretty big deal to kids," said lead researcher Joe Price, an associate professor in the Department of Economics at Brigham Young University in Provo, Utah. For four days in the spring and nine days in the fall, the researchers measured how many fruits and vegetables each student ate during lunch. In the schools that switched recess to before lunch, children ate 54 percent more fruits and vegetables than they did before the switch, the researchers found. Previous studies had attempted to encourage children to eat healthier by increasing the variety of fruits and vegetables available or providing small incentives for the kids to eat them.

Primordial Reptile Fossils Show Mother Caring for Babies The fossilized remains of a small aquatic reptile surrounded by six babies suggest that the extinct animal was caring for the little ones when they died, a new study finds. The reptile is an extinct species called the philydrosaurus, and likely lived during the Early Cretaceous, a time period that spans about 145 to about 100 million years ago. An anonymous farmer donated the "beautifully preserved skeletons" to the Jinzhou Museum of Paleontology in northeastern China in 2010, the scientists added.

The X-ray-based method can be used to decipher the charred, damaged texts that were found in the ancient town of Herculaneum without having to unroll them, which could damage them beyond repair, scientists say. One problem with previous attempts to use X-rays to read the scrolls was that the ancient writers used a carbon-based material from smoke in their ink, said study co-author Vito Mocella, a physicist at the National Research Council in Naples, Italy. "The papyri have been burnt, so there is not a huge difference between the paper and the ink," Mocella told Live Science.
