The European Space Agency says it is switching off its radio link to the probe that landed on a comet, after receiving no signal from the lander for a year. The agency says the decision to shut down a communications instrument on the Rosetta spacecraft Wednesday was taken to conserve energy. Rosetta had used the instrument to communicate with its lander, Philae, which touched down on comet 67P/Churyumov-Gerasimenko in November 2014. During the next two months, Rosetta will use its remaining power to conduct scientific measurements before it crash-lands on the comet Sept. 30. Data collected by Rosetta and Philae have improved scientists' understanding of comets and the role they played in the
Police officers in the U.S. are more likely to stop or arrest black, Hispanic and Native American people than they are to stop or arrest non-Hispanic white people, a new study finds. The researchers also found that more blacks, Hispanics and Native Americans were killed and injured by police over the study period than non-Hispanic whites. "Both blacks and white Hispanics are four times as likely to be killed by the police as white non-Hispanics are," said lead study author Ted Miller, a senior research scientist at the Pacific Institute for Research and Evaluation in Maryland.
A recent Pew Research Center survey and accompanying focus group spells out how Americans feel about using biomedical innovation to alter the human body and its performance capacity. The center asked Americans about the use of gene editing, brain chips and synthetic blood enhancements and found that most have little interest in melding man with machine. Let's take a brief look at three interesting findings from Pew's latest survey—and ask yourself where you fall in the mix. First, consider your religious commitment. Do you pray or attend religious services often, occasionally, or not at all? Survey participants who reported practicing a faith less often than others “are more inclined to see
The chairman of the House Science Committee threatened further action Wednesday after the New York and Massachusetts attorneys general refused to comply with congressional subpoenas seeking records about their investigations into whether Exxon Mobil misled investors about man-made climate change. Texas GOP Rep. Lamar Smith said he was disappointed that New York Attorney General Eric Schneiderman and Massachusetts Attorney General Maura Healey refused to comply with subpoenas he issued two weeks ago.
Spanish troops intervened Tuesday as a wildfire near the eastern city of Valencia spread to a nature reserve after laying waste to some 1,400 hectares (3,500 acres) of land, regional authorities said.
The mysterious, missing Malaysia Airlines Flight MH370 likely crashed off the coast of Australia or hundreds of miles to the north, researchers in Italy said. The potential crash area overlaps with the underwater zone that investigators are now scouring for hunks of metal debris. Search efforts have so far failed to reveal why and where the airliner wrecked more than two years ago, taking with it 239 passengers and crew members.
A nocturnal species of weasel with a robber-mask-like marking across its eyes has returned to the remote ranchlands of western Wyoming where the critter almost went extinct more than 30 years ago. Wildlife officials on Tuesday released 35 black-footed ferrets on two ranches near Meeteetse, a tiny cattle ranching community 50 miles east of Yellowstone National Park. Black-footed ferrets, generally solitary animals, were let loose individually over a wide area.
NEWS BRIEF Using remote sensing technologies, U.S. archaeologists have unlocked a lost piece of early North American history—all without actually digging. The fort of San Marcos, located in present-day Parris Island, South Carolina, was one of five forts that existed in 1577 in the Spanish colonial town of Santa Elena, the remains of which were first uncovered almost 40 years ago. After two years of research, Chester DePratter of the University of South Carolina and Victor Thompson of the University of Georgia were able to uncover the missing fort by employing ground-penetrating radar, soil testing, and monitoring magnetic fields to detect the landscape of the ancient settlement. The 16th-century
Jupiter's Great Red Spot is such a crazy, turbulent storm that it creates sound waves that travel hundreds of miles up and actually heat the planet's upper atmosphere. That's the conclusion of scientists who found a striking hotspot right above the Great Red Spot. They describe their finding Wednesday in the journal Nature. The Great Red Spot is a vast storm about 10,000 miles wide — around 1.5 times the size of Earth. "It's the largest storm in the solar system," says James O'Donoghue, a researcher at Boston University's Center for Space Physics. "I guess, really, it's the largest storm we know about anywhere, so far." This storm has screaming winds that blow up to 350 miles per hour, he says.
People who identify as transgender should not be considered to have a mental health disorder, according to a new study from Mexico. The World Health Organization currently lists transgender identity as a mental health disorder, and the new study is the first in a series of research aimed at finding out whether this categorization is apt. In the new study, published today (July 26) in the journal The Lancet Psychiatry, the researchers investigated whether the distress and dysfunction associated with transgender identity were the result of social rejection and stigmatization or an inherent part of being transgender.
A footprint measuring over a meter wide that was made by a meat-eating predator some 80 million years ago has been discovered in Bolivia, one of the largest of its kind ever found. The print, which measures 1.2 meters (1.3 yards) across, probably belonged to the abelisaurus, a biped dinosaur that once roamed South America, said Argentine paleontologist Sebastian Apesteguia, who is studying the find. The print was found some 64 kilometers (40 miles) outside the city of Sucre in central Bolivia by a tourist guide earlier this month.
Super volcanic eruptions are so catastrophically powerful that they could devastate the entire planet. In a worst case scenario, these kinds of eruptions can eject 1000s of cubic kilometers of magma and ash in the matter of days or few months. That much ash in the atmosphere could block out the light and heat of the sun for years or decades. Unlike most volcanic eruptions, what makes super-eruptions different is that they are unable to erupt easily.
US military bases along the Atlantic Ocean and Gulf of Mexico will be increasingly vulnerable to floods and power-packed storms as the planet warms, researchers said Wednesday. The report by the Union of Concerned Scientists spanned 18 military bases, and found that many risk losing land and strategic assets in the coming decades due to sea level rise. The analysis was based on two different projections of sea level rise and how it may affect US bases from Florida to Maine.
Four cloned sheep that are genetically identical to Dolly, the first cloned mammal, are still healthy even in old age, a new study found. The four sheep, which were derived from the same batch of cells as Dolly and could be considered her clone "sisters," have just reached their 9th birthday, which is equivalent to age 70 in human years, researchers who have been studying the sheep said. All of the sheep were free from many diseases commonly found in older sheep, such as diabetes and high blood pressure, the study showed.
University of Washington biology professor Adam Summers no longer has to coax hospital staff to use their CT scanners so he can visualize the inner structures of stingray and other fish. Last fall, he installed a small computed tomography, or CT, scanner at the UW's Friday Harbor Laboratories on San Juan Island in Washington state and launched an ambitious project to scan and digitize all of more than 25,000 species in the world.
Bayer's (BAYRY) second-quarter figures are the financial equivalent of a glass half-full and half-empty for the German company's management as it ponders the merits of improving a rejected $63.5 billion bid for Monsanto (MON) . The better-than-expected earnings of €3.05 billion ($3.35 billion) lent heavily on the Leverkusen, Germany-based company's strong pharmaceuticals business and, in doing so, highlighted problems at its agricultural division. For the Monsanto takeover's cheerleaders, including Bayer CEO Werner Baumann, crop science's weakness may be seen as justification for the acquisition. In this narrative the Monsanto purchase will supercharge performance at an underperforming business by creating the world's largest agricultural chemicals and seeds business.
Carrier, who saw himself as the Thomas Edison of air conditioners, changed the world with his invention—but its original aims were much smaller than that. The air conditioner, built to both cool a room and reduce humidity, was originally created to keep moist air in a printing plant from wrinkling magazine pages. Research he produced for the company saved them $40,000 a year, and Carrier was put in charge of a new department of experimental engineering, where he designed his first air-conditioner for the printing plant.
Retired NASA astronaut Mark Kelly and his wife, former Arizona congresswoman Gabrielle Giffords, will address the Democratic National Convention (DNC) in Philadelphia today (July 27), presumably about gun violence in America. In January 2011, Giffords was shot in the head during a meeting with constituents at a Tucson supermarket. She survived, but six other people present at the event were killed. Since that tragic event, both Giffords and Kelly have been outspoken advocates of the need for more gun control, and it appears they will address this topic today at the DNC. "Gabby & I are excited to speak at @DemConvention on Wed. about why @HillaryClinton will make our country safer," Kelly said
With antibiotic-resistant super bugs on the rise, researchers are on an urgent hunt for other bacteria that might yield chemicals we can harness as powerful drugs. Scientists once found most of these helpful bacteria in soil, but in recent decades this go-to search location hasn't delivered. Now, researchers at the University of Tübingen in Germany say that to find at least one promising candidate, we need look no further than our own noses. The scientists report Wednesday in the journal Nature that a species of bacteria inside the human nose produces a substance capable of killing a range of bacteria, including the strain of drug-resistant Staphylococcus aureus known as MRSA. The Tübingen team
These questions affect parents and children of every race and ethnicity, and though the substance of individual conversations may differ, the underlying advice on how to talk to kids doesn't change, experts said: Meet them where they are, encourage openness and don't expect that a single conversation will cover the topic. "It's OK to make a mistake," in conversation with a child, said Kimberly Seals Allers, the founder of MochaManual.com, an online destination for parents of color. Black parents don't have the luxury of ignoring color, Allers told Live Science.
Good news: China claims it has discovered the world's largest hole. On Wednesday, state broadcaster CCTV announced that the newly found "dragon's hole," a 984-foot (300-meter) cavern in the disputed waters of the South China Sea, is now the world's largest hole. With territorial claims by Vietnam, Malaysia, Indonesia, Brunei, the Philippines, Taiwan, and China, the South China Sea — rich in natural resources and crisscrossed by shipping routes — is one of the most militarized areas on the planet. According to Xinhua, the blue hole is called the "eye" by locals and lies within the disputed Paracel Islands, which is claimed by China and Taiwan and Vietnam.
The World Wildlife Fund on Thursday urged Asian states to investigate all tiger breeding centres and crack down on any involved in black-market animal trade. On the eve of the International Day of the Tiger, WWF said it was crucial for governments to identify and close so-called "tiger farms", which are distinct from zoos or breeding centres with a legitimate conservation mission. Tiger farms have been linked to the highly lucrative and internationally prohibited trade in tiger parts.
By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - Apollo astronauts who ventured to the moon are at five times greater risk of dying from heart disease than shuttle astronauts, U.S. researchers said on Thursday, citing the dangers of cosmic radiation beyond the Earth's magnetic field. The study by researchers at Florida State University and NASA found that three Apollo astronauts, including Neil Armstrong, the first person to walk on the moon, or 43 percent of those studied, died from cardiovascular disease, a finding with implications for future human travel beyond Earth. The research, published in the journal Scientific Reports, was the first to look at the mortality of Apollo astronauts, the only people so far to travel beyond a few hundred miles (km) of Earth.
