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
The ALS Association is crediting money raised through the Ice Bucket Challenge for the discovery of a gene they say is among the most common that contribute to the progressive disease. Those who accepted the challenge allowed buckets of ice water to be dumped on their heads to raise awareness of ALS. The challenge became a viral sensation in 2014 and raised more than $100 million for the association. Some of that money helped fund a global effort to help find genetic drivers of the condition called Project MinE. The ALS Association says a paper published this week in the journal Nature Genetics reveals Project MinE researchers have identified the NEK1 gene's connection to ALS. It says understanding
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.
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 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.
The latest El Nino weather phenomenon, which was one of the most powerful on record, has ended but could be replaced by its stormy sister La Nina in the coming months, the UN meteorological agency said Thursday. "Atmospheric indicators that had shown strong El Nino patterns early in 2016 returned to near-average in June and July," the World Meteorological Organization said. El Nino affects rainfall patterns and causes both drought and flooding.
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.
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
"Have a look at that dark purple blob on the left, there." With those words, scientists aboard the Exploration Vessel Nautilus uncovered a marine mystery: a small purple orb tucked halfway under a rock off the coast of California. Researchers are so far stumped as to what the colorful, bumpy little ball might be. Their best guess is that it might be a gastropod (a mollusk such as a snail or slug that belongs to the class Gastropoda) called a pleurobranch — and possibly a new species. "None of the known species of California pleurobranch are purple," said Susan Poulton, a spokeswoman for the E/V Nautilus expeditions.

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.
Maps can tell us a great deal about the world we live in. Maps are how we find our way in the world, and how we relate to the other places and things around us. Rebbelib are made of bamboo sticks and cowrie shells, with the shells denoting the locations of islands in the chain.
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.
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 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.
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.
British physics professor Brian Cox taught students at St. Paul's Way Trust School in London on Tuesday how to create fire with methane gas. The school is hosting a science summer school and invited the celebrity physicist, who says he hopes the project will bring in those from different backgrounds. "There is no shortage of enthusiasm for students and young people when you talk about science and engineering," Cox said.
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.
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
The Wall Street Journal reports that by changing the DNA make-up of tomatoes, researchers were able to target the gene responsible for pectate lyase, the enzyme at fault for softening your ruby red tomatoes by breaking down cell walls. After said enzyme was toyed with, the tomatoes showed no signs of wrinkling after two weeks.
Let’s start with the ending: you don’t need to wash your jeans. Unless there are spots or stains you want to remove or they’ve just gotten terribly dirty, with normal wear jeans don’t need washing, according to Tech Insider. Given the wide selection of
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.
The Perseids, one of the most popular meteor showers of the year, is coming up in just under a month. Right now, we are in the middle of a meteor shower called the Delta Aquarids, which began around July 12. Tonight and tomorrow, the Delta Aquarids will reach their peak.
