U.S. spacecraft reaches dwarf planet Ceres for 16-month study

The dwarf planet Ceres taken by NASA's Dawn spacecraftBy Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - A U.S. space probe slipped into orbit around Ceres, a miniature planet beyond Mars believed to be left over from the formation of the solar system, NASA said on Friday. Launched in 2007, the Dawn spacecraft made a 14-month tour of the asteroid Vesta before steering itself toward Ceres, the largest body in the asteroid belt between Mars and Jupiter. Dawn shifted its path to allow itself to be captured by Ceres’ gravity at 7:39 a.m. EST, becoming the first spacecraft to orbit a dwarf planet.

Astronomers find star speeding out of the galaxy

The star, known as US 708, is traveling at about 746 miles (1,200 km) per second, fast enough to actually leave the Milky Way galaxy in about 25 million years, said astronomer Stephan Geier with Germany-based European Southern Observatory, which operates three telescopes in Chile. US 708 is not the first star astronomers have found that is moving fast enough to escape the galaxy, but it is the only one so far that appears to have been slingshot in a supernova explosion. Before it was sent streaming across the galaxy, US 708 was once a cool giant star, but it was stripped of nearly all of its hydrogen by a closely orbiting partner.

Hubble captures quadruple image of ancient exploding star

Hubble Space Telescope image shows multiple images of a single distant supernovaBy Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - Astronomers using the Hubble Space Telescope and a naturally occurring cosmic magnifying lens captured surprising multiple images of the same exploded ancient star, research published on Thursday shows. The four images captured by Hubble were caused by light taking different paths around a massive galaxy cluster located between the exploded star and the Earth-orbiting telescope. By chance, the supernova, which exploded about 9 billion years ago, was aligned with the intervening galaxy cluster being used during a Hubble observation period in 2011. “The supernova team was looking at these image and bam, up popped not one, not two, not three, but four images,” said astronomer Jennifer Lotz, with the Space Telescope Science Institute in Baltimore, Maryland.

Fresh coat: scientists develop tough new self-cleaning paint

British and Chinese scientists say they have developed a new paint that can be applied to clothes, paper, glass and steel to make resilient surfaces that can self-clean even after being scratched or scuffed. In research published in the journal Science on Thursday, the scientists said the paint, made from coated titanium dioxide nanoparticles, is extremely repellent to water but, unlike other waterproof coatings, continues to work even when damaged or exposed to oil. "The biggest challenge for self-cleaning surfaces is finding a way to make them tough enough to withstand everyday damage," said Claire Carmalt, a professor of inorganic chemistry at University College London, who co-led the research.

Fewer Americans Say Vaccines Are Crucial

The percentage of Americans who consider vaccines crucial for children has declined slightly in the past decade, according to a new survey. And 30 percent of Americans now say they've heard "a great deal" about the disadvantages of vaccines, compared to 15 percent who said that in 2001. The percentage of Americans who say they consider vaccines to be worse than the diseases they prevent has not changed much in 14 years: 9 percent of Americans held this view in 2015, compared with 6 percent in 2001. Only 6 percent of Americans say they think vaccines cause autism, while 41 percent say that vaccines do not cause autism, and 52 percent said they were unsure.

'Chappie': How Realistic Is the Film's Artificial Intelligence?

'Chappie': How Realistic Is the Film's Artificial Intelligence?The new film "Chappie" features an artificially intelligent robot that becomes sentient and must learn to navigate the competing forces of kindness and corruption in a human world. Directed by Neill Blomkamp, whose previous work includes "District 9" and "Elysium," the film takes place in the South African city of Johannesburg. One of these robots, named "Chappie," receives an upgrade that makes him sentient. Yet, while today's technology isn't quite at the level of that in the film, "We definitely have had major aspects of systems like Chappie already in existence for quite a while," said Wolfgang Fink, a physicist and AI expert at Caltech and the University of Arizona, who did not advise on the film.

170-Year-Old Shipwreck Beer Smells Gross

170-Year-Old Shipwreck Beer Smells GrossIf hints of soured milk and burnt rubber, or a "goaty" taste sound delightful to you, then brews that were aged for 170 years at the bottom of the Baltic Sea might just be your thing. Scientists recently opened two bottles of beer from a shipwreck off the coast of Finland to get a profile of the 19th century brews. The bottles came from 165 feet (50 meters) below the surface of the Baltic, from the wreckage of a schooner that sank near Finland's Aland Islands in the 1840s. In 2010, divers found 150 bottles of champagne at the wreck, as well as five beer bottles, though one did not survive the journey back to land.

NASA Dawn Probe Enters Orbit Around Dwarf Planet Ceres, a Historic First

NASA Dawn Probe Enters Orbit Around Dwarf Planet Ceres, a Historic FirstThe year of the dwarf planet has begun. NASA's Dawn probe arrived at Ceres today (March 6) at about 7:39 a.m. EST (1239 GMT), becoming the first spacecraft ever to orbit a dwarf planet. Dawn's observations over the next 16 months should lift the veil on Ceres, which has remained largely mysterious since its 1801 discovery, mission team members say. "It's really going to be exciting to see what this exotic, alien world looks like," Dawn mission director and chief engineer Marc Rayman, who's based at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, told Space.com in late January.

UK scientists work out weight of Sophie the Stegosaurus

This undated handout photo issued by the Natural History Museum, shows an artist's impression of how Sophie, the world's most complete Stegosaurus skeleton, may have looked. Scientists at a British museum have worked out the weight of Sophie, one of the world’s most complete Stegosaurus skeletons, it was reported on Wednesday, March 4, 2015. London’s Natural History Museum says Sophie, a young adult when it died, weighed around 1.6 tons and was about the same size as a small rhinoceros. The scientists worked out the dinosaur's body mass after creating a 3D digital version of its skeleton, calculating the volume of flesh around the bones, and comparing the data with information from similar-sized modern animals. (AP Photo/PA, Bob Nicholls/Natural History Museum)LONDON (AP) — Scientists at a British museum have worked out the living weight of Sophie, one of the world's most complete Stegosaurus skeletons.

Ceres Science: NASA Probe to Study Dwarf Planet's Bright Spots and More

Ceres Science: NASA Probe to Study Dwarf Planet's Bright Spots and MoreThere's something highly reflective on Ceres twinkling at NASA's Dawn spacecraft, and scientists hope to figure out what it is after the probe arrives at the dwarf planet later this week. The bright-spot mystery is just one question Dawn will tackle after it enters orbit around Ceres at about 7:20 a.m. EST (1220 GMT) on Friday (March 6). "Ceres has really surprised us, and the first images have produced some really puzzling features that have got the team, and I think some other people, really excited," Dawn Deputy Principal Investigator Carol Raymond, of NASA's Jet Propulsion Laboratory in Pasadena, California, said during a news conference Monday (March 2). The two bright spots are close to each other inside a 57-mile-wide (92 kilometers) crater that sits at about 19 degrees north latitude on Ceres, which is the largest object in the main asteroid belt between Mars and Jupiter.

Global Warming Brought on California's Severe Drought

Global Warming Brought on California's Severe DroughtCalifornia's severe and ongoing drought is just a taste of the dry years to come, thanks to global warming, a new study finds. "California's warming trend is driving an increase in the risk of drought," said study co-author Daniel Swain, a doctoral student in climate science at Stanford University in California. "Warming in California has made it more probable that when a low precipitation year occurs, it occurs in warm conditions and is more likely to produce severe drought," said lead study author Noah Diffenbaugh, an associate professor in the School of Earth Sciences at Stanford.

Against the Science, Meat Pushes Back into U.S. Diet (Op-Ed)

Dr. Michael Greger is the director of Public Health and Animal Agriculture at the Humane Society of the United States. Every five years, the U.S. Department of Health and Human Services (HHS) and the U.S. Department of Agriculture (USDA) issue the "Dietary Guidelines for Americans," which are intended to encourage individuals to eat a healthful diet. The advisory council's report, just published for the 2015 guidelines, is cause for celebration on many fronts. The nutrition experts who created it seemed to be less susceptible to industry influence, and their report could lead to the most evidence-based dietary guidelines the nation has ever adopted.

Syria's civil war linked partly to drought, global warming

FILE - In this Feb. 2, 2014 file photo, Lebanese police inspectors, investigates the site of a deadly car bomb that exploded near a gas station, in the predominately Shiite town of Hermel, about 10 miles from the Syrian border in northeast Lebanon. Global warming worsened record droughts in war-torn Syria and peaceful California, contributing to the unrest that has torn the Middle Eastern country apart, two new studies say. In what scientists say is one of the most detailed and strongest connections between violence and human caused climate change, researchers from Columbia University and the University of California Santa Barbara trace Syria’s drought to the collapse of farming to the migration of 1.5 million farmers to the cities to poverty to civil unrest. Syria’s drought started in 2007 and went until at least 2010 _ maybe longer with weather records harder to get in wartime. (AP Photo/Hussein Malla.

Cool Pacific Ocean Slowed Global Warming

Cool Pacific Ocean Slowed Global WarmingThe Pacific Ocean has been a planetary air conditioner for the past two decades, but the relief may soon end, a new study finds. The Pacific and Atlantic oceans undergo decades-long natural oscillations that alter their sea surface temperatures. Over the past 130 years, the tempo of global warming has revved up or slowed down in tune with changing ocean temperatures, researchers reported today (Feb. 26) in the journal Science. The Pacific Ocean wielded its mighty influence starting in 1998, when it interrupted the rapid climb of global temperatures, the study reported.

'Big Brain' Gene Found in Humans, Not Chimps

'Big Brain' Gene Found in Humans, Not ChimpsA single gene may have paved the way for the rise of human intelligence by dramatically increasing the number of brain cells found in a key brain region. This gene seems to be uniquely human: It is found in modern-day humans, Neanderthals and another branch of extinct humans called Denisovans, but not in chimpanzees. By allowing the brain region called the neocortex to contain many more neurons, the tiny snippet of DNA may have laid the foundation for the human brain's massive expansion. "It is so cool that one tiny gene alone may suffice to affect the phenotype of the stem cells, which contributed the most to the expansion of the neocortex," said study lead author Marta Florio, a doctoral candidate in molecular and cellular biology and genetics at the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden, Germany.

Cooler Pacific has slowed global warming, briefly: study

A man and a girl paddle in the Pacific Ocean at sunset in Santa MonicaBy Alister Doyle OSLO (Reuters) - A natural cooling of the Pacific Ocean has contributed to slow global warming in the past decade but the pause is unlikely to last much longer, U.S. scientists said on Thursday. The slowdown in the rate of rising temperatures, from faster gains in the 1980s and 1990s, has puzzled scientists because heat-trapping greenhouse gas emissions from factories, power plants and cars have hit record highs. Almost 200 nations are due to agree a U.N. deal to slow climate change in Paris in December. Examining temperatures of the Pacific and Atlantic Oceans back to 1850, which have natural swings in winds and currents that can last decades, the scientists said a cooler phase in the Pacific in recent years helped explain the warming hiatus.

Scientists discover black hole so big it contradicts growth theory

This artist's concept illustrates a supermassive black holeBy Colin Packham SYDNEY (Reuters) - Scientists say they have discovered a black hole so big that it challenges the theory about how they grow. Scientists said this black hole was formed about 900 million years after the Big Bang. "Based on previous research, this is the largest black hole found for that period of time," Dr Fuyan Bian, Research School of Astronomy and Astrophysics, Australian National University (ANU), told Reuters on Wednesday. "Current theory is for a limit to how fast a black hole can grow, but this black hole is too large for that theory." The creation of supermassive black holes remains an open topic of research.

Obesity Is Complicated and Needs New Approach, Scientists Say

With obesity rates continuing to rise around the globe and the majority of Americans now obese or overweight, it's easy to see that we are losing the battle of the bulge. Aside from isolated areas of improvement where people are, in fact, losing weight — in a city here, a neighborhood there — no country has succeeded in reversing its obesity epidemic. In a series of six critical articles covering the health, policy, economics and politics of obesity, scientists lay out what society has been doing wrong and call for a new global action plan to meet what they call the "modest" goal of the World Health Organization: no increase in the prevalence of obesity from now through 2025. "There are clear agreements on what strategies should be implemented and tested to address obesity," said Christina Roberto, an assistant professor of social and behavioral sciences and nutrition at the Harvard School of Public Health, and lead author of the first report of the series.

Robert Copeland, a follower of Boston sports and an entomologist at the International Centre of Insect Physiology and Ecology in Nairobi, told the newspaper that the wasp’s yellow and black colouring resembles a Boston Bruins jersey. The research also was underwritten by the government of Finland, where Rask was born.  "This species is named after the acrobatic goaltender for the Finnish national ice hockey team and the Boston Bruins, whose glove hand is as tenacious as the raptorial fore tarsus of this dryinid species," the authors wrote in the paper, which is due to be published in March in the scientific journal Acta Entomologica Musei Nationalis Pragae.  Rask told the newspaper he was unaware of any animals named after him, other than the occasional fan’s pet cat or dog.

Scientists find peanut-eating prevents allergy, urge rethink

By Kate Kelland LONDON (Reuters) - In research that contradicts years of health advice, scientists said on Monday that babies at risk of developing a childhood peanut allergy can avoid it if they are given peanuts regularly during their first 11 months. The study, the first to show that eating certain foods is an effective way of preventing allergy, showed an 80 percent reduction in the prevalence of peanut allergies among high-risk children who ate peanuts frequently from infanthood, compared to those who avoided them. "This is an important clinical development and contravenes previous guidelines," said Gideon Lack, who led the study at King's College London. "New guidelines may be needed to reduce the rate of peanut allergy in our children." Rates of food allergies have been rising in recent decades, and peanut allergy now affects between 1 and 3 percent of children in Western Europe, Australia and the United States.

Corrected - U.S. FDA approves 23andMe's genetic screening test for rare disorder

(In 6th paragraph, corrects to show that four patient were treated for infections at the hospital, not that they developed infections at the hospital) By Toni Clarke WASHINGTON (Reuters) - Google-backed 23andMe won U.S. approval on Thursday to market the first direct-to-consumer genetic test for a mutation that can cause children to inherit Bloom syndrome, a rare disorder that leads to short height, an increased risk of cancer and unusual facial features. The Food and Drug Administration said it plans to issue a notice to exempt this and other carrier screening tests from the need to win FDA review before being sold. "This action creates the least burdensome regulatory path for autosomal recessive carrier screening tests with similar uses to enter the market," the agency said in a statement, referring to genetic mutations carried by two unaffected parents. The FDA previously barred Mountain View, California-based 23andMe from marketing a saliva collection kit and personal genome service designed to identify a range of health risks including cancer and heart disease, saying it had not received marketing clearance.
