  • Facebook’s secret censorship rules protect white men from hate speech but not black children
    mark_zuckerberg (Credit: Reuters/Stephen Lam) In the wake of a terrorist attack in London earlier this month, a U.S. congressman wrote a Facebook post in which he called for the slaughter of “radicalized” Muslims. “Hunt them, identify them, and kill them,” declared U.S. Rep. Clay Higgins, a Louisiana Republican. “Kill them all. For the sake of all that is good and righteous. Kill them all.” Higgins’ plea for violent revenge went untouched by Facebook workers who ...

  • Repeated radiation warnings go unheeded at sensitive Idaho nuclear plant
    (AP Photo/John Bazemore, File) (Credit: AP) Ted Lewis knew the plutonium plates at the government lab where he worked could leak potentially lethal radioactive dust. He had seen it occur in the 1970s, when he was helping load some of those plates into a nuclear reactor at the lab near Idaho Falls, Idaho. A steel jacket enclosing one of the plates somehow cracked, spilling plutonium oxide particles into the air. But Lewis and his colleagues ... Read more...

  • NASA keeps a close eye on tiny stowaways
    Pasadena CA (JPL) Jun 28, 2017 Wherever you find people, you also find bacteria and other microorganisms. The International Space Station is no exception. That generally is not a problem. For one thing, the space station is kept cleaner than many environments on Earth. Routine cleaning activities are included on astronaut task schedules. Cargo sent to the station, and the vehicles that carry it, undergo a rigorous clean ... Read more...

  • Mars rover Opportunity on walkabout near crater rim
    Pasadena CA (JPL) Jun 26, 2017 NASA's senior Mars rover, Opportunity, is examining rocks at the edge of Endeavour Crater for signs that they may have been either transported by a flood or eroded in place by wind. Those scenarios are among the possible explanations rover-team scientists are considering for features seen just outside the crater rim's crest above "Perseverance Valley," which is carved into the inner slope ...

  • Snake robot could help maintain space station, explore moon
    Washington (UPI) Jun 20, 2017 Scientists at SINTEF, a research institute in Norway, are working on designs for a snake robot that could one day carry out maintenance missions on the space station and explore lava tubes on the moon. The research is being funded by the European Space Agency, which is intent on establishing an international settlement on the moon. ESA scientists suggest lava tubes, underground tunnels ...

  • AI Will Prepare Robots for the Unknown
    Pasadena CA (JPL) Jun 26, 2017 How do you get a robot to recognize a surprise? That's a question artificial intelligence researchers are mulling, especially as A.I. begins to change space research. A new article in the journal Science: Robotics offers an overview of how A.I. has been used to make discoveries on space missions. The article, co-authored by Steve Chien and Kiri Wagstaff of NASA's Jet Propulsion Laboratory, ... Read more...

  • The curious case of the warped Kuiper Belt
    Tucson AZ (SPX) Jun 23, 2017 An unknown, unseen "planetary mass object" may lurk in the outer reaches of our solar system, according to new research on the orbits of minor planets to be published in the Astronomical Journal. This object would be different from - and much closer than - the so-called Planet Nine, a planet whose existence yet awaits confirmation. In the paper, Kat Volk and Renu Malhotra of the University ... Read more...

  • Small scale, big improvements
    Newark DE (SPX) Jun 16, 2017 Methods to improve water purification or build better batteries are problems that have challenged scientists for decades. Advances have inched forward, but rising demand moves the finish line further and further away. At the same time, the chemical reactions that make these improvements possible occur at scales invisible to the naked eye (the atomic scale) where liquids and solid surfaces ... Read more...
