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
For the first time, SpaceX has fired the Raptor rocket engine Elon Musk and his company intend to use to send people to the Red Planet. SpaceX founder Elon Musk tweeted photos of the Raptor rocket engine churning out streams of fiery exhaust Monday morning. In a tweet, Musk stated that "SpaceX propulsion just achieved first firing of the Raptor interplanetary transport engine." The announcement of the first successful firing comes a day before a speech at the International Astronautical Congress in Mexico where Musk will be discuss his plans for sending humans to other planets in our solar system.
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.
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".
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
Finally, the veil of mystery around the origins and spread of ancient cats is beginning to lift. The first large-scale genetic study of domesticated cats has revealed a huge amount of information about how early feline companiions boarded boats that would take them around the world, hitching rides with all sorts of ancient cultures, including the Vikings. Cats first began developing an affinity with humans around the dawn of agriculture, some 12,000 years ago. The study, presented at the 7th International Symposium on Biomolecular Archaeology in Oxford, Britain, suggests that the first of these domesticated cats were descended from wild cats that would chase small rodents in fields planted by early farmers.
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.
India made the announcement three weeks after it said that it wouldn't be able to ratify the agreement this year due to "domestic procedures." However, India agreed to sign it after several rounds of meetings between Modi and United States President Barack Obama. "Today, on the birth anniversary of Deendayal Upadhyay , I announce that India will ratify the decisions (formally join the Paris Agreement) on October 2, the birth anniversary of Mahatma Gandhi," Modi said during BJP's national council meet in Kozhikode.
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
On Monday, India sent a rocket into space which successfully launched eight satellites in one go. The main purpose of the launch which took place at the Sriharikota space centre off India's eastern coast, was to put into orbit SCATSAT-1, a satellite that will help weather forecasting. Five of the other satellites that were on board are foreign, from the US, Canada and Algeria. In June India launched 20 satellites in a single mission, the most in the history of the country's ambitious space programme. Seventeen of those were foreign. Monday's launch takes the number of foreign satellites launched by India to 79. This has earned the country more than $120m (£92m). And India's space agency has already
There has been an upturn in Singapore's manufacturing sector, as output emerges from the red in August. According to the latest figures by the Singapore Economic Development Board manufacturing output increased 0.1% in August 2016.
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.
Canada's parks department on Monday confirmed the discovery of a British exploration ship that vanished during a storied Arctic expedition in 1846. The statement comes two weeks after scientists from the Arctic Research Foundation announced they had found the ship -- part of a two-vessel expedition during which both disappeared -- submerged but well-preserved beneath 24 meters of water in the Northwest Passage. "Parks Canada's underwater archaeology team is proud to confirm that the wreck located in Terror Bay on the south-west side of King William Island, Nunavut is that of HMS Terror," the government agency said.
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.
Tonight Hillary Clinton and Donald Trump will take the stage for their first presidential debate. And while science topics aren't likely to get much airtime during the back-and-forth, the website ScienceDebate.org has given us a preview of where the candidates stand on a variety of science-related issues. ScienceDebate.org is a nonprofit, nonpartisan organization, backed by a long list of science organizations, business representatives, and Nobel Laureates, that has been advocating since the 2008 election for a presidential debate devoted entirely to science topics. That hasn't happened yet, but this year the candidates agreed to answer 20 questions about science, health, technology, and environmental
On Monday morning, the Zhejiang Geely Holding Group—which owns Chinese car brand Geely as well as Volvo and the London Taxi Company—announced that it is now the main sponsor and official automotive partner of the Bloodhound SSC land speed record project. The three-year deal includes both financial and technical support for the project, as well as an extension of Bloodhound SSC's STEM in schools promotion across China. Richard Noble, the main driving force behind Bloodhound SSC (and both previous land speed records) said "We could not have a better partner than Geely: not only are they an international technology company with tremendous vision and capability, they share our passion for innovation
Correcting the irregular heartbeat of an arrhythmia with a standard defibrillator can be a shocking experience that jolts the patient and sometimes leaves residual damage to the very heart muscle that the technique is trying to fix. A team of researchers from John Hopkins University hopes to change this by developing a kinder and gentler process that uses light pulses — directed toward the heart — to fix an arrhythmia without any significant damage to the heart. The Optogenetics defibrillator can reset a heart arrhythmia using a gentle pulse of light that corrects the arrhythmia slowly instead of through the jolting punch used by the electrical shock method.
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
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.
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%.
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.
Ever wonder what the computer-generated Transformer robots in director Michael Bay's movies would look like in real life? A Turkish company has the answer, with a fully functional Transformer prototype. In a series of videos, the company Letvision unveiled a transforming robot built from a BMW 3 Series coupe.
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.
Unless it does more, the United States probably will fall short of goals set under last year's Paris agreement to dramatically reduce emissions of heat-trapping gases, according to a new study. The U.S. pledged to reduce its greenhouse gas emissions in 2025 by 26 to 28 percent below 2005 levels. Looking at all types of greenhouse gases from energy and other sources— carbon dioxide, methane, nitrous oxide, and various fluorocarbons — two scientists at the U.S. Department of Energy's Lawrence Berkeley National Lab figure the U.S. will have to cut about 1,660 million tons of annual emissions.
