    Musk's SpaceX successfully tests rocket engine that could help us colonize Mars

    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.

    Mother Uncovers Lasting Impact of Son's Organ Donation

    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

    Climate change may be irreversible

    Current greenhouse gas concentrations could warm the world 3-7℃ (and on average 5℃) over coming millennia. That’s the finding of a paper published in Nature today. The research, by Carolyn Snyder, reconstructed temperatures over the past 2 million years. By investigating the link between carbon dioxide and temperature in the past, Snyder made new projections for the future. The Paris climate agreement seeks to limit warming to a “safe” level of well below 2℃ and aim for 1.5℃ by 2100. The new research shows that even if we stop emissions now, we’ll likely surpass this threshold in the long term, with major consequences for the planet. What is climate sensitivity? How much the planet will warm

    U-2 Spy Plane Crash: Why 'Cold War' Aircraft Are Still Relevant Today

    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.

    China Builds The World's Largest Radio Telescope

    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.

    Over 90% of world breathing bad air: WHO

    Nine out of 10 people globally are breathing poor quality air, the World Health Organization said Tuesday, calling for dramatic action against pollution that is blamed for more than six million deaths a year. New data in a report from the UN's global health body "is enough to make all of us extremely concerned," Maria Neira, the head of the WHO's department of public health and environment, told reporters. Poorer countries have much dirtier air than the developed world, according to the report, but pollution "affects practically all countries in the world and all parts of society", Neira said in a statement.

    In Shift, Most Americans Now Say President Should Release All Medical Records

    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.

    Researchers think chaos theory can get us past Moore's Law

    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

    Stephen Hawking says humanity needs to venture into space for our survival

    In a book excerpt published by The Guardian, Hawking contends that humans need to venture deep into space for the sake of adventure and the survival of our species. "We are entering a new space age, one in which we will help to change the world for good," Hawking said in the How To Make A Spaceship book excerpt. "The probable life span of human civilization is much greater if we’re a multi-planet species as opposed to a single-planet species," Musk said in 2015.

    African elephants 'suffer worst decline in 25 years'

    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".

    Drug Overdose Cluster in Canada Tied to Opioid-Laced Cocaine

    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.

    The Last Black Moon Until 2019 Will Rise In the Sky on Friday Night

    When it comes to rare lunar events, September 2016 seems to be the month that keeps on giving: This Friday, September 30, a Black Moon will rise in the skies of the Western Hemisphere, a phenomenon we haven't seen since March 2014. The Black Moon, which will occur at 8:11 p.m. ET on Friday, will only be happening in the Western Hemisphere because, technically, the new moon will happen on October 1 for the Eastern Hemisphere (they'll be getting their Black Moon at the end of next month). The next time two new moons will fall in the same calendar month in the Americas will be July 2019.

    US not on track to meet 2025 carbon pollution cutting goal

    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.

    Why students who do well in high school bomb in college

    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'

    Try riding a roller coaster to dislodge those painful kidney stones

    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%.

    Why India's commercial space programme is thriving

    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

    Canada confirms Arctic discovery of 200-year-old ship

    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.

    How Two Astronomers Accidentally Discovered the Big Bang

    Nowadays, it's a universally accepted theory that the universe began 13.8 billion years ago with the Big Bang. But did you know that two radio astronomers unintentionally stumbled upon its discovery? In the 1960s, Robert Wilson and Arno Penzias were measuring the brightness of the sky with their radio telescope. No matter where they pointed it, they picked up an inexplicable droning sound. What initially sounded like a mistake ended up being the discovery of a lifetime.
