The world's largest radio telescope began searching for signals from stars and galaxies and, perhaps, extraterrestrial life Sunday in a project demonstrating China's rising ambitions in space and its pursuit of international scientific prestige. Beijing has poured billions into such ambitious scientific projects as well as its military-backed space program, which saw the launch of China's second space station earlier this month. Measuring 500 meters in diameter, the radio telescope is nestled in a natural basin within a stunning landscape of lush green karst formations in southern Guizhou province. It took five years and $180 million to complete and surpasses that of the 300-meter Arecibo Observatory
The methane-fueled engine is expected to form part of the Dragon rocket, with Musk suggesting the engines are three times more powerful than the current Merlin engines that SpaceX uses on its Falcon 9 rocket. The engine was fired at the company's McGregor, Texas facility, according to a report by tech website Engadget and comes ahead of a long-awaited speech by Elon Musk. USA Today reported on Sunday that Musk would outline his ideas for how to establish a city on Mars within a decade. The speech is due to be held at the International Astronautical Congress in Guadalajara, Mexico, and Musk is expected to detail a new system called the "Mars Colonial Transporter," that could deliver 100 people to the planet Mars.
The number of African elephants has dropped by around 111,000 in the past decade, a new report released Sunday at the Johannesburg conference on the wildlife trade said, blaming the plummeting figures on poaching. The revelation, the worst drop in 25 years, came amid disagreement on the second day of the global meet over the best way to improve the plight of Africa's elephants, targeted for their tusks. With Namibia and Zimbabwe, wanting to be allowed to sell ivory stockpiles accrued from natural deaths to fund community elephant conservation initiatives, Zimbabwe's Environment Minister Oppah Muchinguri rejected the "imperialistic policies" of opposing countries, branding them a "clear infringement on the sovereign rights of nations".
A U-2 spy plane that crashed in northern California earlier this week, killing one of the two pilots, focused attention on a normally clandestine aspect of the U.S. military. The U-2 plane has a long and storied history that stretches back to the late 1950s, but how is the reconnaissance aircraft used today? U-2 planes have been flown by the United States and other nations for more than 60 years, as both a spy plane and an instrument of science.
ST. LOUIS • A joint effort between Washington University and the University of Pennsylvania received a $23.6 million federal grant to start a new Science and Technology Center. The partnership, fueled by the five-year grant, creates the Science and Technology Center for Engineering MechanoBiology. It's an effort to understand how single cells work, what they react to and how they can be used or developed to prevent diseases, boost crop practices and more. Single cell organisms are the root of all plants and animals. "Being named an STC is a prestigious distinction reserved for sweeping research projects that have the power to change lives. We're ready to get to work," Guy Genin, principal researcher
A majority of Americans now say that a U.S. president should release all of his or her medical information. The poll, which was conducted by Gallup last week, found that a slim majority of Americans, 51 percent, said that a president should release all medical information that might affect that person's ability to serve in office, whereas 46 percent said that a president should have the right to keep those medical records private. The new poll results are a change from the results in 2004, when just 38 percent of Americans said that a president should release all of his or her medical information, and 61 percent said that a president should be able to keep those records private, according to Gallup.
Just ask any one of the 300,000 Americans who, in any given year, develop kidney stones: What if the excruciating pain of passing one of those little devils could be prevented by strapping yourself into a make-believe runaway mine train, throwing your hands in the air and enduring G-forces as high as 2.5 for about three minutes? In a bit of medical research inspired by strange and remarkable patient accounts, a Michigan State University urologist reports that, yes, riding a medium-intensity roller coaster such as the Disney theme parks’ Big Thunder Mountain Railroad can result in the painless passing of small, and even a few large, kidney stones. For best results, ride in the back, where — roller coaster afficionados all seem to agree — the thrills are greatest. Independent of kidney stone volume and location, findings reported Sunday in the the Journal of the American Osteopathic Assn. showed that sitting in the back of the roller coaster resulted in an average passage rate of 63.89%.
Gordon Moore, co-founder of Intel, believed that the number of transistors on an integrated circuit would double every year or two. And, to his credit, that rule pretty much held out between 1965 and 2015, when the laws of physics began to get in the way. Now, researchers at North Carolina State believe that we don't need to obsess over ever-smaller transistors to make chips even more powerful. Instead, they've turned to chaos theory in the hope that mixing things up will provide the performance boost that Intel can't. Lead researcher Behnam Kia explains that we are now "reaching the limits of physics in terms of transistor size." If you've ever listened to one of Intel's presentations, you'll
Libertarian Party presidential nominee Gary Johnson raised plenty of eyebrows on Sunday by declaring that mankind eventually will have to flee to the far reaches of outer space to save itself when the Earth finally either succumbs to global warming or is obliterated by the sun. "We do have to inhabit other planets,” Johnson explained to George Stephanopoulos, host of ABC News’ This Week.
An ultrasound showed one of Sarah Gray's unborn twins was missing part of his brain, a fatal birth defect. His brother was born healthy but Thomas lived just six days. Latching onto hope for something positive to come from heartache, Gray donated some of Thomas' tissue for scientific research — his eyes, his liver, his umbilical cord blood. Only no one could tell the Washington mother if that precious donation really made a difference. So Gray embarked on an unusual journey to find out, revealing a side of science that laymen seldom glimpse. "Infant eyes are like gold," a Harvard scientist told her. "I don't think people understand how valuable these donations are," said Gray, who hadn't grasped
Strollers and cyclists can breathe easy on the banks of the Seine after Paris on Monday approved a plan to ban cars on a long stretch of riverside road cutting across the city. A centrepiece of her battle against pollution, the plan has divided opinion in the French capital. "We need to slow down a bit, let go, stop and relax," said Violetta Kolodziejczak, a restaurant greeter.
Prime Minister Narendra Modi said India will ratify the Paris Agreement climate change pact on Oct 2. Modi’s announcement on Sunday is seen as a major boost to the implementation of measures at international level in an attempt to control global warming. Modi added that the country has chosen Oct. 2 to coincide with the birth anniversary of Mahatma Gandhi, who lived his entire live with minimum carbon footprint.
The first year of college is a tough transition, and for many students, a disillusioning one. A study conducted last fall at the University of Toronto found that incoming students arrived with unreasonably optimistic expectations. On average, students predicted they would earn grade-point averages of 3.6. Those dreams were swiftly punctured. By the end of the year, the average freshman had only a 2.3. What separated the high-achievers from the low-achievers? As any college admissions counselor will tell you, high school grades have always been the single best predictor of college success. But that does not mean that high school grades are good predictors. Research shows that differences in students'
Hugo Fearnley of Whitby, England is studying the potential of bee-produced medicines for the treatment of human diseases. Fearnley, CEO of BeeVital and Director of the Apiceutical Research Centre (ARC), recently earned a Churchill Travelling Fellowship to fund his research and coalition-building in four African countries. One potentially promising compound for Fearnley is propolis, sometimes called bee glue: a mixture of plant resins and wax used for structural purposes in hives.
Two biologists have been honored with MacArthur "Genius Grants," the MacArthur Foundation announced today (Sept. 22). The MacArthur "Class of 2016" list of 23 fellows represents exceptional achievements in the sciences and arts, as well as in the advancement of human rights and advocacy for social change.
At 3 a.m. on the morning of May 17, 2012, the town of Timpson, Texas, was awoken by the largest earthquake ever measured in the eastern half of the state. Earthquakes do not often strike Texas: Timpson is closer to tornado alley than the Pacific ring of fire. Timpson isn’t even in West Texas, where the state’s worst quakes have historically taken place.
It’s a case of pulsar ping-pong. Repeating radio bursts from space may be the result of pulsars colliding with asteroids in faraway stellar systems. Fast radio bursts (FRBs) are a rare and mysterious phenomenon. Until recently, we had seen fewer than 20 of these milliseconds-long pulses of radio waves, and they have been attributed to everything from quasars to aliens. Last year, astronomers at the Arecibo Observatory in Puerto Rico nearly doubled the number of observed FRBs when they saw 16 bright bursts from the direction of FRB 121102, where a single burst had been detected in 2012. Such repeating FRBs add another layer to the mystery. It’s possible that all FRBs repeat but our telescopes
The Great Barrier Reef stretches 2,300 kilometres down Australia's east coast – that's a lot of area to monitor. Aerospace manufacturer Boeing and the Australian Institute of Marine Science have signed a five-year agreement to develop advanced monitoring capabilities to better understand the health of the Great Barrier Reef. Brisbane-based engineers from Boeing will team up with marine scientists to develop innovative sea-to-space technologies including unmanned aerial vehicles, satellites and autonomous underwater vehicles. “Working with Boeing will provide an ideal platform from which we can paint a detailed picture of what is happening on the reef,” AIMS chief John Gunn, a member of the Great Barrier Reef Foundation’s International Science Advisory Committee, said in a press release.
More than 40 people in a Canadian city were treated for an opioid overdose this summer after they smoked crack cocaine that had been contaminated with an opioid drug related to fentanyl, according to a new report. In mid-July, a hospital in the city of Surrey, British Columbia, experienced a large spike in patients needing treatment for an opioid overdose — about 11 patients per day needed treatment, up from the usual four patients per day. Most of the patients had become unconscious after smoking what they thought was crack cocaine, the report said.
A snow-covered former US army base in Greenland -- dubbed "a city under ice" -- could leak pollutants into the environment as the climate changes, raising difficult questions over who is responsible for a clean-up. In 1959, US army engineers began constructing a futuristic project in northwestern Greenland that might as well have been lifted from a Cold War spy movie. A network of tunnels under the snow contained everything from research facilities to a hospital, a cinema and a church -- all powered by a small, portable nuclear reactor.
This week’s debate between Donald Trump and Hillary Clinton is the first of three the candidates will engage in before the November election. As in years past, each debate will be broadly aimed at one of three single subject areas—domestic policy, the economy and foreign policy. For the last several election cycles, a consortium of Nobel Prize winners and American scientific associations has been pushing for a fourth separate debate devoted entirely to science issues. (Newsweek covered this effort in-depth.) They argue that in our rapidly advancing, high-tech world, with the greatest global challenge being man-caused climate change, voters need to understand where candidates get their scientific
Paul Scharre, a former Army Ranger and the director of the 20YY Future of Warfare Initiative at the Center for a New American Security, said performance-enhancers that are being explored could offer tremendous operational advantages for warfighters. DARPA has launched 4MM, a project to develop a device that could enable dismounted troops to run a four-minute mile, a benchmark normally reserved for the world’s most elite runners. “The underlying theory there is if you can provide some forward push to … the wearer, can you make it so they can run faster,” said Mike LaFiandra, chief of the dismounted warrior branch in the human research and engineering directorate at the Army Research Laboratory, where 4MM prototypes have been tested. With DARPA funding, researchers at Arizona State University developed a system called Air Legs.
Virtually all of us have done it: furiously cram for a test or some other high-stakes event very shortly before it's slated to start. And you can bet to varying degrees that the respective presidential campaigns of Hillary Clinton and Donald Trump are working day and night to prepare their candidates for Monday's debate, and the two debates after that. Reportedly, Clinton and Trump are getting ready for their face-off in very different ways. But what does research say about the best way to prepare for tests, or debates, or what have you? Is cramming smart? 1) First, here's a 2011 article for the American Psychological Association by Lea Winerman. In "Study Smart," she acknowledges that, in particular,
"Arianespace confirms its status as the most reliable launch services provider in the marketplace." -- Arianespace I have to admit, when Arianespace made this boast last week -- just days after I penned a column ranking the success records of the big three space launchers United Launch Alliance (ULA), Arianespace, and SpaceX, in that order -- my eyebrows raised a bit. At last count, United Launch Alliance -- the Boeing (NYSE:BA) and Lockheed Martin (NYSE:LMT) joint venture -- had successfully launched 111 rockets into orbit, in a row, without any of them blowing up in the process. Airbus-controlled (NASDAQOTH:EADSY) Arianespace, on the other hand, with an enviable record of 73 straight successful
