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.
Solar Impulse 2 — the experimental solar plane which first set out on its circumnavigation attempt in 2015 — has just landed in Abu Dhabi, its final landing spot and the city where its around-the-world bid began. Piccard and his fellow Solar Impulse pilot André Borschberg set out on this world tour to raise awareness about solar power and clean technology that could one day change the way we travel. Solar Impulse 2 is making use of energy efficient batteries and other technologies that could one day help make flight more fuel efficient and friendly for the environment.
Israel's national museum is set to display a 2,200-year-old Egyptian mummy of a man who was afflicted with some modern-day illnesses such as osteoporosis and tooth decay, the museum said on Tuesday. The mummy is the only such relic in Israel, named the "Protective Eye of Horus," after a pharaonic deity. It was kept for decades at a Jesuit institute in Jerusalem before it was loaned to the Israel Museum.
When it comes to height, Dutch men and Latvian women tower over all other nationalities, a study reveals. The average Dutchman is now 183cm (6ft) tall, while the average Latvian woman reaches 170cm (5ft 7in). The research, published in the journal eLife, has tracked growth trends in 187 countries since 1914. It finds Iranian men and South Korean women have had the biggest spurts, increasing their height by an average of more than 16cm (6in) and 20cm (8in). In the UK, the sexes have gone up virtually in parallel by about 11cm (4in). "Mr Average" in Britain is now 178cm (5ft 10in) tall; Ms Average stands at 164cm (5ft 5in). This contrasts for example with men and women in the US, where the height
Futuristic technologies that promise to improve people's strength and smarts by editing genes, implanting brain chips or super-charging blood have raised more concern than enthusiasm among Americans, a poll showed on Tuesday. The survey by the Pew Research Center included more than 4,700 US adults, and is considered a nationally representative sample. The prospect of brain implants that could increase intelligence and focus also raised concern for 69 percent of people, as did the potential of synthetic blood that could improve speed, strength and stamina (63 percent).
It was definitely déjà vu in the media today. Reuters, The New Yorker, Los Angeles Times, and more were back on the "brain training prevents dementia" bandwagon. STAT's headline was particularly boosterish: Play on! In a first, brain training cuts risk of dementia years later. It's just a few months since the US Federal Trade commission fined a company $2 million for false advertising based on brain training claims like this. And in October 2014, an international scientific consensus statement tried to stem this tide. Yet here we are again. Sigh! This time, the results aren't even just getting the usual claim of being "promising": in the STAT article, they're "highly, highly promising"! And that's
Researchers found the world's deepest underwater sinkhole in the South China Sea. As local fishermen tell it, the deep blue “Dragon Hole” in the Paracel Islands, called the “eye” of the South China Sea, is where the Monkey King in “Journey to the West” acquired his famous golden cudgel. After nearly a year of exploration, Chinese researchers have determined that the underwater sinkhole is likely the world’s deepest, reaching about 987 feet below the surface and surpassing the previous record holder, Dean’s Blue Hole near the Bahamas, by more than 300 feet, Xinhua News Agency reported. Blue holes are named as such for their rich, dark blue coloring, a stark contrast to the otherwise aqua waters that surround them.
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.
Unfortunately, we can't go back in time to sample the oxygen content of prehistoric air. The mass spectrometer measured the oxygen content of the prehistoric air and found that the air 800 million years ago was about 10 percent oxygen.
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.
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 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.
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.
Millions of children will suffer disproportionately from the failed harvests and devastated livelihoods left behind by the El Nino weather phenomenon, Save the Children warned Tuesday. El Nino affects rainfall patterns and causes both drought and flooding. As it recedes the Pacific cooling trend known as La Nina is set to begin.
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.
Archaeologist Arnoldo Gonzalez said researchers believe the tomb and pyramid were purposely built atop a spring between AD 683 and 702. Attention has focused on the heavily carved stone sarcophagus in which Pakal was buried, and which some erroneously believe depict the Maya ruler seated at the controls of a spaceship. The director of archaeology for the National Institute of Anthropology and History, Pedro Sanchez Nava, said the theory makes sense in light of other pre-Hispanic peoples, such as those who lived at Teotihuacan, near Mexico City, where another water tunnel was found.
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

Past earthquakes that damaged ancient temples perched high in the Himalayas could be harbingers of dangerous quakes to come, new research suggests. "The supporting pillars and temple structures are tilted with respect to their original positions.
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.
By Kate Kelland LONDON (Reuters) - Scientists in Germany have discovered a bacteria hiding out in peoples' noses that produces an antibiotic compound that can kill several dangerous pathogens, including the superbug MRSA. The early-stage finding, reported in the journal Nature on Wednesday, could one day lead to a whole new class of antibiotic medicines being developed to fight drug-resistant bacterial infections, the researchers said. As well as being a focal point for many viral infections, the nasal cavity is also a rich ecosystem of 50 or so different species of bacteria, lead researcher Andreas Peschel of the University of Tuebingen told reporters in a telephone briefing.
It took a group of researchers from five different countries including India, Japan, Canada, the U.S. and France but we’ve finally learned (and it should come as no surprise because they’re indestructible) that cockroaches are the fountain of youth. The highly disgusting, Diploptera punctata AKA Pacific Beetle Cockroach — which is the only known viviparous cockroach. Meaning that like humans, the Pacific Beetle Cockroach gives birth to live babies rather than hatching eggs.
