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
If you want to see a tall population of men, go to the Netherlands. National height averages are useful as an indicator of nutrition, health care, environment and general health that people have experienced from the womb through adolescence, said Majid Ezzati of Imperial College London, who led the research. The tallest men in the new analysis were Dutch, with an average height of about 6 feet (182.5 centimeters).
A computerized brain training program cut the risk of dementia among healthy people by 48 percent, U.S. researchers said on Sunday in reporting an analysis of the results of a 10-year study. The preliminary findings, presented at the Alzheimer's Association International Conference in Toronto, are the first to show that any kind of intervention could delay the development of dementia in normal, healthy adults. To date, cognitive psychologists and neuroscientists have largely rejected evidence that computer-based cognitive-training software or "brain games" have any effect on cognitive function. The new findings would be quite promising if they hold up through peer review and publication in a scientific journal, said Dr. John King, an expert in social research at the National Institute of Aging.
What began as a brush fire last Friday rapidly morphed into a raging blaze over the weekend, burning more than 33,000 acres and destroying at least 18 homes in Los Angeles County. Only about 10 percent of the wildfire was contained by Sunday night, the Los Angeles County Fire Department reported. “All the experience we’ve had with fires is out the window,” John Tripp, the county’s deputy fire chief, told the Associated Press.

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
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.
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.
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.
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.
Ceres, the largest object in the asteroid belt between Mars and Jupiter, should be riddled with craters. But when NASA's Dawn spacecraft started orbiting the dwarf planet last year, scientists were surprised to find it was relatively smooth. In a study published Tuesday in Nature Communications, researchers conclude that something mysterious must have erased the marks. Given the pockmarked appearance of most asteroid belt objects — including Vesta, the asteroid that Dawn visited before arriving at Ceres — scientists expected many large craters to pepper their planetary target. “Ceres is thought to have formed at the dawn of the solar system, some one to ten million years or so after the onset
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.
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.
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
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 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.
The main wreckage from flight MH370, which disappeared over the Indian Ocean more than two years ago, is likely to be found in zone further north than the area currently being searched, scientists have revealed. Additional washed-up debris could be recovered off the coasts of Tanzania, Mozambique as well as on the islands of Madagascar, La Reunion or the Comoros. The disappearance of Malaysian Airline flight MH370 is one of the greatest mysteries in the history of aviation.
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
As local fishermen tell it, the deep blue “Dragon Hole” in the Xisha 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. Researchers with the Sansha Ship Course Research Institute for Coral Protection began exploring Dragon Hole, known as Longdong, in August 2015 and completed the project last month, Xinhua reported.
With the Delta Aquarid meteor shower going on right now, and the crowd-favorite Perseid meteor shower hot on its heels, the next few weeks are going to be the prime-time to watch some shooting stars light up the night sky. NASA is on the lookout for any cosmic objects on a crash course with our planet, and it's found that the chances of us colliding with a comet or asteroid anytime soon are pretty low. If a comet of this size struck Earth, then the energy of the impact would be about as much as 300 times that of the asteroid that scientists believed wiped out the dinosaurs, Donald Yeomans, a senior research scientist at NASA's Jet Propulsion Laboratory, told LiveScience.
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.
The clock is ticking for the rats, possums and weasels that have invaded New Zealand over the past few hundred years. Before humans landed in New Zealand less than 800 years ago, precious few mammals lived on the islands — a vibrant archipelago that provided a home for flightless birds, such as the kiwi, takahe and kakapo parrot, as well as geckos and lizard-like tuataras. "While once the greatest threat to our native wildlife was poaching and deforestation, it is now introduced predators," Key said in a statement.

Solar Impulse 2 on Monday neared the end of its epic journey to become the first sun-powered airplane to circle the globe without a drop of fuel to promote renewable energy. When the experimental aircraft touches down in Abu Dhabi it will cap a remarkable 42,000-kilometre (26,097 mile) journey across four continents, two oceans and three seas. Solar Impulse 2 was expected to enter UAE airspace at around 1:30 am local time on Tuesday (2130 GMT Monday), and land in Abu Dhabi at around 4:00 am (0000 GMT).
When Leonardo da Vinci was doodling, he was figuring out some of the fundamental laws of physics. In a new paper, Professor Ian M. Hutchings of the University of Cambridge argues that a sketch from da Vinci's journals shows that the Renaissance-era polymath was already working out his own ideas about the concepts of friction years earlier than previously thought. Hutchings argues that the sketches, which had previously been seen as inconsequential, were the first known place that da Vinci began to work out his theory of friction (or "tribology").
