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.
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.
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.
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.
Big is definitely better in the Netherlands and Latvia. Research has shown that Dutch men are the tallest in the world, with the average man clocking in at an imposing 183 centimeters (6 feet). Meanwhile, Latvian women are the tallest among their female peers, with the average woman reaching 170 centimeters (5 feet 7 inches). Fortunately, their national counterparts are not far behind—Dutch women are the second-tallest in the world, while Latvian men are fourth in the male stakes. The study, published Tuesday in the journal eLife, brings together data from 187 countries over a century from 1914 to 2014, tracking growth trends around the world. The research shows that Europe has come to completely
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.
This will warm your heart.
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.
At first glance, Daisy, Debbie, Denise and Diana are like any other sheep, ambling in a green field in Nottingham, England, chewing cud and minding their own business. The reason — they are clones of the most famous sheep in history. “‘Sister clones’ probably best describes them,” Kevin Sinclair, a professor of developmental biology at the University of Nottingham, and the lead author of the first detailed and comprehensive assessment of age-related non-communicable diseases in cloned organisms, told NPR.
Almost all living things need oxygen to survive. The Earth’s atmosphere is currently around 21 percent oxygen, but it didn’t always provide that big of a breath of fresh air to its inhabitants. Millions and billions of years ago, oxygen levels were much lower, but exactly how low was unclear. Now, a remarkable discovery has been made by a team at Brock University in Canada by studying 815-million-year-old air bubbles, preserved in rock salt. They’ve found that oxygen levels were five times what was originally thought at that time. Their results show that oxygen existed in abundance well before the appearance of complex animals, and it calls into question the evolution of these life forms, long
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
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.
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.
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.
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 world's first round-the-world flight to be powered solely by the sun's energy made history Tuesday as it landed in Abu Dhabi, where it first took off on an epic 25,000-mile (40,000-kilometer) journey that began more than a year ago. Since its March 2015 take off, the Swiss-engineered Solar Impulse 2 has made 16 stops across the world without using a drop of fuel to demonstrate that using the plane's clean technologies on the ground can halve the world's energy consumption, save natural resources and improve quality of life. After landing the plane, pilot Bertrand Piccard was greeted outside the cockpit by his Solar Impulse partner and fellow pilot Andre Borschberg.
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.
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.
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.
The number of young kids in Colorado who accidentally consume marijuana has increased since buying the drug for recreational use became legal there in 2014, according to a new study. During 2009, before the recreational use of marijuana was legalized in Colorado, only nine calls were made to a regional poison center regarding kids accidentally ingesting or inhaling marijuana, researchers found. "We anticipated that the rate would likely go up" after the recreational use of marijuana was legalized in Colorado, said study co-author Dr. Genie Roosevelt, a pediatrician at Denver Health Medical Center.
The Ice Bucket Challenge is being credited with helping to raise significant funds that have allowed researchers to identify a gene found to be one of the most common in people with the deadly disease that affects neurons in the brain and spinal cord. The Challenge became a sensation two summers ago and involved participants, including many athletes and celebrities, pouring ice water over their heads to help raise awareness of amyotrophic lateral sclerosis, better known as Lou Gehrig's disease. The effort raised more than $100 million in contributions for the ALS Association, which contributed $1 million to the Project MinE research project. "The ALS Ice Bucket Challenge enabled us to secure funding from new sources in new parts of the world," said Bernard Muller, an entrepreneur who suffers from the progressive disease and helped start the research project.
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 billion years ago, sometime around Earth's 560 millionth birthday, Luca was born. Luca is your great-to-an-infinite-degree grandmother and grandfather, as it is your dog's and your goldfish's and your ficus'. Every living thing on Earth owes it existence to Luca, whose very name stands for "Last Universal Common Ancestor." It is the origin of life on Earth, from which the rest of us evolved. And now scientists believe they have mapped a genetic picture of the qualities that would have belonged to Luca, giving us a startling look at how life on Earth might have begun: ...By comparing their sequence of DNA letters, genes can be arranged in evolutionary family trees, a property that enabled
