    Top of page. I aim for "special."

    To me, the most fascinating question in science and spirituality, excellent new article. http://www.bbc.com/earth/story/20170...uantum-physics




    Quantum consciousness" is widely derided as mystical woo, but it just will not go away.



    Perhaps the most renowned of its mysteries is the fact that the outcome of a quantum experiment can change depending on whether or not we choose to measure some property of the particles involved.
    When this "observer effect" was first noticed by the early pioneers of quantum theory, they were deeply troubled. It seemed to undermine the basic assumption behind all science: that there is an objective world out there, irrespective of us. If the way the world behaves depends on how – or if – we look at it, what can "reality" really mean?

    THIS IS WHERE IT ALL GETS VERY MEANINGFUL

    John Wheeler, and this "delayed choice" experiment was performed in the following decade.....It turns out that, just as Bohr confidently predicted, it makes no difference whether we delay the measurement or not .....
    It is as if nature "knows" not just if we are looking, but if we are planning to look.
    OUR BRAINS USE ELECTRONS AND PHOSPHATE WITHIN MICROTUBLES THAT "SHOULD" REQUIRE AN OBSERVER TO COLLAPSE TO PARTICLES, BUT WHO IS OBSERVING WHAT IS IN THE BRAIN?



    The article is a brilliant survey of the big questions.


    I can't get around the fact that it seems that our universe is set up specifically for consciousness, and the only "observer" as to what is inside our brains might well be a soul that is independent of our biochemical selves. That or it's a higher power. Wedding science and religion, God.


    That's just me. I've posted before on general idea, and always love the responses.

    Can't resist a story entitled: https://www.sciencenews.org/article/...ce-junk?tgt=nr

    Gecko-inspired robot grippers could grab hold of space junk


    Most strategies for sticking don’t work in space. Chemical adhesives can’t withstand the wide range of temperatures, and suction doesn’t work in a vacuum.
    Adhesives inspired by gecko feet — which use van der Waals forces to cling without feeling sticky could fit the bill, says Mark Cutkosky of Stanford University, whose team has been designing such stickers for more than a decade. Now his team has built robotic gripper “hands” that can grapple objects many times their size without pushing them away.
    Gripper hands could be used to repair or move dead satellites, or help miniature satellites called CubeSats stick to larger spacecraft like barnacles, Parness says

    Should be top of fold news in every paper: https://www.sciencenews.org/article/...about-get-real


    Quantum computers are about to get real





    The most advanced computers are working with fewer than two dozen qubits. But teams from industry and academia are working on expanding their own versions of quantum computers to 50 or 100 qubits, enough to perform certain calculations that the most powerful supercomputers can’t pull off. The race is on to reach that milestone, known as “quantum supremacy.
    Some of the first useful problems quantum computers will probably tackle will be to simulate small molecules or chemical reactions. From there, the computers could go on to speed the search for new drugs or kick-start the development of energy-saving catalysts to accelerate chemical reactions. To find the best material for a particular job, quantum computers could search through millions of possibilities to pinpoint the ideal choice, for example, ultrastrong polymers for use in airplane wings. .....

    Advertisers could use a quantum algorithm to improve their product recommendations — dishing out an ad for that new cell phone just when you’re on the verge of purchasing one.


    One of the most famous potential uses for quantum computers is breaking up large integers into their prime factors. For classical computers, this task is so difficult that credit card data and other sensitive information are secured via encryption based on factoring numbers. Eventually, a large enough quantum computer could break this type of encryption, factoring numbers that would take millions of years for a classical computer to crack.

    If you are on the road, or in the air, and just want to "listen to something," and veg, I cannot recommend this more. Hilarious, fascinating, deep, moving .... you will not regret the time. Talk was given about 8 years ago in Seattle. If anyone saw it, stand up.

    Biggest iceberg on record. http://www.huffingtonpost.com/entry/...ushpmg00000009

    ‘Bergxit’: One Of The Largest Icebergs On Record Set To Break From Antarctic Shelf



    For over two years, the U.K.-based Project MIDAS has been monitoring a large, fast-moving rift in the Larsen C ice shelf, located on the northern end of the Antarctic Peninsula. On Wednesday, researchers with the European Space Agency released a detailed analysis of the soon-to-be iceberg.

    It’s expected to rise some 620 feet above the ocean’s surface — roughly the height of St. Louis’ Gateway Arch — and contain about 277 cubic miles of ice, according to ESA. Below the surface, the iceberg could reach a depth of nearly 700 feet.

    Surface of a Mouse Retina

    The retina, located at the back of the eye, contains light-sensitive cells responsible for converting light into electrical nerve signals that the brain can process. As a result of aging or injury the retina can lose this function, causing vision loss. This image was created by digitally stitching together over 400 images to form one large image, so as to show the entire surface of a mouse retina. Blood vessels (blue) can be seen radiating from the centre of the image, supplying the entire retinal surface. Astrocytes, specialist cells of the nervous system, are double stained in red and green. These cells perform many functions – including maintaining and delivering nutrients to the nerves and the brain, and supporting the repair processes of the brain and spinal cord following injury – and are important for nerve survival and regeneration. Here, scientists are researching whether the function of astrocytes changes during retinal degeneration, which may lead to the development of new treatments for vision loss.

    I read the other day in the Nat. Geo that a polar bear mother swam for 9 straight days and some 425 miles in the Beaufort Sea to reach a ice flow...that is simply amazing to me...unfortunately her cub did not make it.....

    How can anyone not click on a headline like this: https://www.sciencenews.org/article/...teamy-doughnut

    Earth might once have resembled a hot, steamy doughnut



    Earth may have taken on a jelly doughnut shape early in its history. The rocky planet was spinning through space about 4.5 billion years ago when it smacked into a Mars-sized hunk of rotating rock called Theia, according to one theory (SN: 4/15/17, p. 18). That hit may have turned Earth into a synestia, a blob of mostly vaporized rock with an indented center, resembling a slightly squished jelly doughnut, new simulations suggest

    There are times I may have wondered!

    BTW; I missed your great post above regarding the meteorite older than Earth, that's just great stuff. Fascinating. Thanks for posting and I'd love to have more people post on this thread. There's so much interesting stuff happening and it gets little coverage, everything seems political. I think it's great to be a little better rounded, like a dounut.

    Posted something similar a while ago, but this quick video (less than 3:00) takes you back 250 million years in plate tectonics, and then 250 million years into the future.

    Another first for possibly the second most amazing machine man has ever built - Keppler, (First is obviously Hubble).

    Astronomers may have found an exomoon, and Hubble is going to check https://www.sciencenews.org/article/...exomoon-hubble



    The first evidence for an exomoon — a moon orbiting a planet orbiting a distant star — may have been spotted in data from the Kepler space telescope. But surprisingly, exomoons in general may be rare, at least around planets close to their stars.
    A second, smaller dip that appears ahead of or behind the planet could reveal a moon. Such exomoons, researchers have speculated, may be among the best places in the universe to look for extraterrestrial life. But because those signals are faint and inconsistent, they take a lot of computing power to find. Kipping has been searching for such signals for years in a project called the Hunt for Exomoons with Kepler.

    This is a special one, from The Atlantic: https://www.theatlantic.com/science/...statue/535782/


    A Dinosaur So Well Preserved It Looks Like a Statue


    [When we look at dinosaurs in museums, it takes imagination to plaster flesh and skin on top of the bones. But for the dinosaur that Funk unearthed—a 110-million-year-old creature named Borealopelta—imagination isn’t necessary. It looks like a sculpture. And based on pigments that still lurk within the skin, scientists think they know what colors the animal had. “If someone wants to come face to face with a dinosaur, and see what it actually looked like, this is the one for that,” says Caleb Brown from the Royal Tyrrell Museum, who has studied the animal.[




    Borealopelta was one of the ankylosaurs—a group of heavy-set, low-slung, tank-like dinosaurs. It lacked the shin-thwacking tail clubs that some of its relatives wielded, but its back was covered in heavy, armored scales, and a pair of 20-inch-long spikes jutted from its shoulders. It weighed 1.5 tons and was 20 feet from foot to tail. And it probably couldn’t swim very well.


    Somehow, this particular individual ended up at sea. Perhaps it got careless on a shoreline. Perhaps it drowned in a flood and was washed out to sea. Either way, gases started building up in its body, causing it to float belly-up. As those gases released, the dead dinosaur sank, and hit the ocean floor hard enough to leave a small crater. Before sharks had a chance to nibble it, or worms had a chance to bury into its bones, it was quickly smothered by fine sediment and sealed off from the outside world. There it remained for millions of years, until March 11, 2011, when an excavator bit into it.

    The ankylosaur clearly deserved special attention, but because of its delicate state, it was assigned to a single pair of steady hands.

    Those hands belonged to technician Mark Mitchell, who compares the process of separating dinosaur from rock to chipping concrete chunks from a surface as soft as compressed talcum powder. It took him 7,000 hours over 5.5 years, during which he did little else.
