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
Could cloning an adult mammal, they wondered, make the clone adult-like right from birth. Maybe clones were not meant to live very long. Scientists at the UK’s University of Nottingham just released a study showing that clones can lead long, healthy lives after all.
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
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.
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.
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.
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. This would surpass the Dean's Blue Hole
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.
A legal saga involving five Native American tribes and a group of scientists—which may now be drawing to a close—began on July 28, 1996. On that day, exactly 20 years ago, their differences of perspective were thrown into dramatic relief with the discovery of a skull on the bottom of the Columbia River near Kennewick, Wash. The coroner called in a forensic anthropologist, Jim Chatters, and the two returned to the site where the skull was found, where they unearthed a nearly complete skeleton.
Hillary Clinton’s campaign is hoping to capitalize on yet another controversial proclamation from Donald Trump: That global warming is a hoax. Trump, the Republican presidential nominee, has said he rejects the scientific consensus on climate change and opposes most U.S. efforts to reduce greenhouse gas emissions and curb fossil fuel use. Trump’s anti-climate stance is the focus of a new short film, directed by James Cameron, that will play tonight at the Democratic National Convention in Philadelphia.
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
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.
Jupiter’s Great Red Spot is the largest storm in the solar system. Located in Jupiter's lower atmosphere, this storm living is so big that you could fit two or three Earths inside of it. Now, a team of scientists at Boston University believe that it might just offer an explanation for one of the biggest mysteries about Jupiter.
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.
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.
By Susan Kelly CHICAGO (Reuters) - Even though many doctors see need for improvement, surgical robots are poised for big gains in operating rooms around the world. Robotic surgery has been long dominated by pioneer Intuitive Surgical Inc, which has more than 3,600 of its da Vinci machines in hospitals worldwide and said last week the number of procedures that used them jumped by 16 percent in the second quarter compared to a year earlier. The anticipated future growth - and perceived weaknesses of the current generation of robots - is attracting deep-pocketed rivals, including Medtronic Inc and a startup backed by Johnson & Johnson and Google.
A Chinese rocket body streaking across the night sky over the Western United States lit up social media as people shared photos and video of the bright object. The Chinese CZ-7 re-entered the atmosphere Wednesday night, U.S. Strategic Command spokeswoman Julie Ziegenhorn confirmed. Photographer Ian Norman was taking pictures of the night sky with friends in Alabama Hills, California, near the eastern Sierra Nevada, when he saw the light and started recording, thinking the flash was a meteor.
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.
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.
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.
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.
THURSDAY, July 28, 2016 -- Former Apollo astronauts have up to five times the rate of heart-related deaths that their Earth-bound peers do, a new study shows. And researchers suspect that exposure to deep space radiation may be the reason why. "We know very little about the effects of deep space radiation on human health, particularly on the cardiovascular system. This gives us the first glimpse into its adverse effects on humans," said Michael Delp, dean of the College of Human Sciences at Florida State University in Tallahassee. The Apollo space program ran from 1961 to 1972. It included 11 manned space flights, some of which went to the moon. Nine of those missions went beyond Earth's orbit
