Car coolant rejected by Daimler is safe, say EU scientists
EU scientists have found that the new car coolant at the centre of a dispute that has pitched regulators against Germany and its luxury carmaker Daimler does not pose any serious safety risks, the European Commission said on Friday. The Commission, the EU executive, has launched legal proceedings against Germany over Daimler's refusal to stop using an old-style coolant that has global warming potential more than 1,000 times greater than that of carbon dioxide. The suggested substitute, which has roughly the same impact as carbon dioxide, is the R1234yf coolant developed by U.S. conglomerate Honeywell in partnership with Dupont.
Israeli scientists shoot for the moon with dishwasher-sized spacecraft
By Steven Scheer JERUSALEM (Reuters) - It's only the size of a dishwasher and weighs as much as giant panda, but its inventors are hoping this spacecraft will go where no other Israeli vessel has gone before - to the moon. Working on a shoestring budget, the Israeli scientists and engineers building the shuttle - temporarily named "Sparrow" - believe it will land on the moon by the end of 2015, a feat only the United States, Russia and China have managed so far. The landing will be the toughest task in the Sparrow's mission, not least because of the moon's many mountains and craters, said Yariv Bash, an electronic engineer and the founder of SpaceIL, the group building the spacecraft. The $20 million prize will go to the first team to land a spacecraft on the moon, make it jump 500 meters and transmit images and video back to earth.
Study pinpoints source of Mars meteorites
After traveling millions of years, some eventually landed on Earth, becoming the biggest of three main types of meteorites hailing from the Red Planet. Now researchers say they have pinpointed the source of those Martian meteorites classified as the "shergottites." The finding, if confirmed, would give scientists fresh insights into Mars' history and evolution. "If one were able to say, 'Oh, this Martian meteorite is from exactly this spot on Mars,' then that would have significant added value to what you could get out of it," said Carl Agee, meteorite curator and director of University of New Mexico's Institute of Meteoritics. University of Oslo planetary scientist Stephanie Werner and colleagues say they have done just that.
As scientists watch, distant asteroid disintegrates
By Will Dunham WASHINGTON (Reuters) - Patsy Cline's classic country song "I Fall to Pieces," has nothing on this one. The rocky asteroid, named P/2013 R3, was one of the innumerable objects populating the crowded asteroid belt located between the orbits of Mars and Jupiter, roughly three times further away from the sun than Earth. This time, however, scientists first noticed the dramatic events using ground-based telescopes in Arizona and Hawaii and then got a better look using the orbiting Hubble Space Telescope. "After looking at the asteroid belt for a couple of hundred years - the first one was discovered in 1801 - to find a new thing like this is really exciting," David Jewitt, a UCLA astronomer who led the research, said in a telephone interview.
'Sicilian Space Program' launches pastry into stratosphere
By Naomi O'Leary ROME (Reuters) - Sicilian amateur scientists have launched a model cannolo, a cream-stuffed pastry roll symbolic of the Italian island, into the stratosphere, capturing bizarre images of the dessert flying far above the earth. The 'Sicilian Space Program', which cost a rough total of 350 euros, had symbolic importance as well as being a scientific feat, the three natives of the island town of Enna behind it told Reuters. We wanted to lift up Sicily in our own way," said filmmaker Fabio Leone, 34, who recorded the project with Antonella Barbera, 38. It rose to at least 29,768 meters according to Paolo Capasso, 37, a computer technician responsible for the careful calculations behind the launch on February 2.
Free Birth Control Has Little Effect on Women's Sexual Behavior, Study Suggests
Offering free contraception to women and teenage girls does not cause them to increase their risky sexual behavior over time, a new study suggests. Researchers found that after receiving free birth control, most women reported no change in their number of sexual partners, and only a modest increase in sex frequency, from an average of four times a month before getting free birth control to six times a month after receiving it. "We didn't see women engage in multiple sex partners after providing them with no-cost contraception," said Gina Secura, project director of the Contraceptive CHOICE Project and the study's lead author. Moreover, there was no increase in sexually transmitted infections among the women who received free contraception, said Secura, who is also an epidemiologist in the department of obstetrics and gynecology at the Washington University School of Medicine in St. Louis.
Wastewater Injection Triggered Oklahoma's Earthquake Cascade
One of Oklahoma's biggest man-made earthquakes, caused by fracking-linked wastewater injection, triggered an earthquake cascade that led to the damaging magnitude-5.7 Prague quake that struck on Nov. 6, 2011, a new study confirms. The findings suggest that even small man-made earthquakes, such as those of just a magnitude 1 or magnitude 2, can trigger damaging quakes, said study co-author Elizabeth Cochran, a seismologist with the U.S. Geological Survey. The Prague earthquake was the largest of thousands of quakes that rattled Oklahoma in late 2011. The 2011 quakes struck along the Wilzetta fault, a fault zone near Prague.
Which US State Has the Healthiest Habits?
Healthy living appears to be common in Vermont: Residents of the state were the most likely in the nation to say they exercised frequently and ate their veggies, according to a new Gallup-Healthways poll. In 2013, 65.3 percent of adults living in Vermont said they exercised for at least 30 minutes, three times a week ? the most of any state, the poll found. Hawaii came in second, with 62.2 percent of residents saying they reached this level of exercise, followed by Montana and Alaska, both at 60.1 percent. The states in which people were the least likely to report frequent exercise were Delaware, West Virginia, Alabama and New Jersey.
Winklevoss Twins in Space: Not the 1st Identical Siblings to Leave Earth
The Winklevoss twins launched into the headlines Wednesday (March 5) by announcing their plan to ride a Virgin Galactic space plane (and paying with Bitcoins, no less), but they aren't the first set of identical twins to fly in space. NASA, it turns out, got there first. Years before the Winklevoss twins planned their Virgin Galactic space trip, the identical twins Mark and Scott Kelly ? both 50 ? of West Orange, N.J., were busy flying space shuttles for NASA. Not only are the Kelly brothers the first identical twin astronauts in history, but they were also simultaneous captains in the U.S. Navy until Mark Kelly retired from both NASA and the Navy in 2011.
'Cosmos' for a New Generation: Astrophysicist Neil deGrasse Tyson Explains We...
When Neil deGrasse Tyson was 17, Carl Sagan, then the world's most famous astronomer, invited the teenager to spend a day in Ithaca. By Tyson's account, Sagan was a good host. A few years after that visit, Sagan would become America's gentle guide through the universe in his hugely popular series "Cosmos: A Personal Voyage" on PBS. "Cosmos: A Spacetime Odyssey," hosted by Tyson, premieres next weekend on Fox and the National Geographic Channel. In Tyson's view, every generation needs a "Cosmos."

Artful Science Logos Honor Greatest Astronomers and Physicists of All Time (I...
From the ancient Egyptian astronomer Hypatia to modern-day astrophysicist Stephen Hawking, physicists throughout history are getting the artist's treatment in a new set of illustrations honoring the thinkers' contributions to science. Dr. Prateek Lala, a physician based in Canada, has recently crafted playful images using the names of famous scientists to show, in logo form, what they gave to theoretical physics. Called "science typographies" or "logotypes," some of the more striking images include Isaac Newton's apple and Edwin Hubble with the Hubble Space Telescope that eventually flew his name into space. Lala started making his images in 2013 after speaking with a friend about the ways in which people learn, and how to get everyone interested in scientific research.
'Cosmos' Reborn: New Fox TV Show Aims to Bring Science to Everyone
"Cosmos: A Spacetime Odyssey," is a relaunch of Carl Sagan's classic "Cosmos: A Personal Voyage." The new Cosmos series premieres Sunday (March 9), and the creators of the show, hosted by astrophysicist Neil deGrasse Tyson, hope that it will reach a wide audience like the Sagan's "Cosmos" did during its run in 1980. "We wanted to reach everyone because we believed that this knowledge is a birthright," Ann Druyan, Sagan's widow and a co-writer of the new show, said of the first "Cosmos" series during a webcast here at the Hayden Planetarium Tuesday (March 4). "Cosmos: A Spacetime Odyssey" uses animation and virtual effects ? including a unique spaceship which Tyson travels on ? to create an immersive TV experience.
The dawning of the age of genomic medicine, finally
By Julie Steenhuysen LA JOLLA, California (Reuters) - When President Bill Clinton announced in 2000 that Craig Venter and Dr. Francis Collins of the National Human Genome Research Institute had succeeded in mapping the human genome, he solemnly declared that the discovery would "revolutionize" the treatment of virtually all human disease. The expectation was that this single reference map of the 3 billion base pairs of DNA -- the human genetic code -- would quickly unlock the secrets of Alzheimer's, diabetes, cancer and other scourges of human health. As it turns out, Clinton's forecast was not unlike President George Bush's "mission accomplished" speech in the early days of the Iraq war, said Dr. Eric Topol of Scripps Translational Science Institute, which is running a meeting On the Future of Genomic Medicine here March 6-7.
It's 3 a.m., Is that a Parasitic Worm in Your Cheek? (Op-Ed)
Jonathan Allen is a professor in the Department of Biology at the College of William & Mary. His teaching, as well as his research, is directed at marine invertebrates and he participates in the William & Mary Marine Science minor. I am a scientist, and therefore not the kind of person who goes down the rabbit-hole looking to self-diagnose a rare disease, but there I was, night-surfing internet health sites trying to figure out what was behind the strange rough spot in my mouth. I began to wonder if some kind of parasite might explain the wandering rough patch in my mouth.
