    unfortunately the original article is subscription only "Among the evidence the article cites for this conclusion is Google's recent hiring of Brian Holtz and Dave Bettinger. Both came from companies (O3b and VT iDirect respectively) that specialize in communication satellites. Google has also invested in O3b and a current Google employee sits on company's board. A Boeing representative told The Information that Facebook and Google are "beginning to show a broader interest in satellite technology." While both companies are looking to space to broaden their reach, the ad-supported Google has the potential resources (cash) and gumption to actually follow through in the immediate future."

    Two apps - the Distributed Electronic Cosmic-ray Observatory (DECO) and Cosmic Rays Found in Smartphones (CRAYFIS) - transform smartphones into miniature cosmic-ray detectors. They use the CMOS chips inside phones' onboard cameras to detect the secondary particles produced when cosmic rays - energetic, charged subatomic particles arriving from beyond the solar system - collide with air molecules in the Earth's atmosphere

    Soft Robots Scientists from Cornell University and the Italian Technology Institute in Pontedera have developed an elastic robotic skin that is able to stretch up to five times its size, change colors, and even detect pressure. The luminescent skin, partly funded by the Army and Air Force's research wings, is comprised of different kinds of specialized silicone, making it flexible and soft.

Researchers find new phase of carbon, make diamond at room temperature - 1 views

    Researchers from North Carolina State University have discovered a new phase of solid carbon, called Q-carbon, which is distinct from the known phases of graphite and diamond. They have also developed a technique for using Q-carbon to make diamond-related structures at room temperature and at ambient atmospheric pressure in air. It turns out this configuration is harder than diamond, plus the material has a very low work function. The latter might be very interesting for electronics or as electrode material.

    Maybe* this is the wonder material with very low workfunction needed in the Photon Enhanced Thermionic Emitter future prototype :)

    "Pérez and his friends were astonished to see the unicorn herd. These creatures could be seen from the air without having to move too much to see them - they were so close they could touch their horns. While examining these bizarre creatures the scientists discovered that the creatures also spoke some fairly regular English. Pérez stated, "We can see, for example, that they have a common 'language,' something like a dialect or dialectic."

    Shocking. I assume that this could indeed have severe implications if it gets in the "wrong hands".

    "Feed it the first few paragraphs of a Guardian story about Brexit, and its output is plausible newspaper prose, replete with "quotes" from Jeremy Corbyn, mentions of the Irish border, and answers from the prime minister's spokesman." https://www.youtube.com/watch?time_continue=37&v=XMJ8VxgUzTc "Feed it the opening line of George Orwell's Nineteen Eighty-Four - "It was a bright cold day in April, and the clocks were striking thirteen" - and the system recognises the vaguely futuristic tone and the novelistic style, and continues with: "I was in my car on my way to a new job in Seattle. I put the gas in, put the key in, and then I let it run. I just imagined what the day would be like. A hundred years from now. In 2045, I was a teacher in some school in a poor part of rural China. I started with Chinese history and history of science." (https://www.theguardian.com/technology/2019/feb/14/elon-musk-backed-ai-writes-convincing-news-fiction)

    It's really lucky that it was OpenAI who made that development and Elon Musk is so worried about AI. This way at least they try to assess the whole spectrum of abilities and applications of this model before releasing the full research to the public.

    They released a smaller model, I got it running on Sandy. It's fairly straight forward: https://github.com/openai/gpt-2
