    *Update, 23 October, 5:40 a.m.: A study from Google claiming quantum supremacy, accidentally leaked online last month, has now been published in Nature. The Google group reiterates its claim that its 53-qubit computer performed, in 200 seconds, an arcane task that would take 10,000 years for Summit, a supercomputer IBM built for the Department of Energy that is currently the world’s fastest. But IBM appears to have already rebutted Google’s claim. On 21 October, it announced that, by tweaking the way Summit approaches the task, it can do it far faster: in 2.5 days. IBM says the threshold for quantum...

    They live in different places, work at different universities and dedicate their careers to studying different topics. But there's one thing at least four of this year's US Nobel Prize laureates share. They're immigrants. That's in keeping with a long-running trend, according to a recent report from the National Foundation for American Policy. Immigrants have won 38% of the Nobel Prizes awarded to Americans in chemistry, medicine and physics since 2000, and 35% of the Nobel Prizes awarded to Americans in those fields since 1901, the foundation says. This year, French-born Esther Duflo and Indian-born Abhijit Banerjee -- both professors...

    NOAA released its official winter outlook Thursday morning, predicting a higher probability for above average temperatures across much of the country, and above average precipitation for much of the Upper Plains, Midwest and Great Lakes. Forecasters say that even though colder than average temperatures are not favored, there will likely be some areas that end up with temperatures below average for the winter season (December-February). The El Niño Southern Oscillation often times influences our winter weather here in the United States, however forecasters with NOAA say we are currently in neutral conditions (neither El Niño or La Niña are present)...

    If you’re interested in eye-popping, attention-grabbing animals, look no further than hybrids. While hybrid animals like this wolf-dog are a fascinating cross of two separate species, they also reveal a host of ethical problems. < . . . > To create this “bear-dog” hybrid—who didn’t actually have any bear DNA—Russian breeders allegedly used a Chow Chow and some other sort of long-nosed stray. As animal shelter volunteer Polina Kefer put it, “This dog is a ‘badly-made’ Chow Chow.” While the four-year-old pooch might’ve looked cool to some, mentally, he was a mess. < . . . > Unfortunately, all of...

    Economy Minister Peter Altmaier has signaled that the government will consider building a space launch center after German industries demanded more to investment in space research and development. “Space travel excites many people and creates thousands of jobs. We are leaders in satellite technology. Therefore, I will examine the suggestion of the Federation of German Industries (BDI) for a spaceport,” he told the mass-circulation Bild. German industry has called for the space innovation budget to more than double from €285 million ($318 million) to a level on par with France at more than €700 million. …

    Lucy team members presented the completed mission design, showing that they have met all the technical challenges of the mission and were ready to start building the actual hardware. At Lockheed Martin in Colorado over the course of four days, an independent review board, comprised of reviewers from NASA and several external organizations, heard all about the mission design. The Trojan asteroids orbit the Sun at a distance of Jupiter. The mission is set to launch in October 2021; with boosts from Earth's gravity, the spacecraft is expected to complete a 12-year journey to seven different asteroids.

    New PragerU Video Shows 2 Scientific Reasons to Doubt Evolution On Monday, PragerU released a video giving two solid scientific reasons to doubt the Darwinian theory of evolution. In the video, Stephen C. Meyer, who earned a Ph.D. in the history and philosophy of science and who serves as a senior fellow at the Discovery Institute, lays out two key flaws in the evolutionary theory that is often taught as gospel truth in may high schools and colleges.Meyer begins the video by quoting evolutionary biologist and New Atheist Richard Dawkins, who claimed that anyone who does not believe in evolution...

    Townhall ^ | 10/22/2019 | Stephen Moore
    Last week, the lobbying arm of the wind energy industry made an unsurprising, though somewhat embarrassing, announcement. It wants a longer lifeline with federal subsidies. So much for wind being the low-cost energy source of the future. Less than a year ago, the American Wind Energy Association with great fanfare issued a press statement that, as Bloomberg reported: "America's wind farms are ready to go it alone." Sen. Chuck Grassley of Iowa, a Republican who has strongly supported the wind industry since the days of federal support began in 1992, boasted that the wind industry had finally "matured" and wind...

    Science Alert ^ | 10/17/19 | Peter Dockrill
    A pair of mathematicians from Australia and France have devised an alternative way to multiply numbers together, while solving an algorithmic puzzle that has perplexed some of the greatest math minds for almost half a century. For most of us, the way we multiply relatively small numbers is by remembering our times tables – an incredibly handy aid first pioneered by the Babylonians some 4,000 years ago. But what if the numbers get bigger? Well, if the figures get unwieldy – and assuming we don't have a calculator or computer, of course – most of us would then turn to...

    All across the Universe, trillions of galaxies can be seen, with each one typically containing billions and billions of stars. Here on Earth, life not only arose, thrived, and became complex and differentiated, but intelligent, technologically advanced, and even spacefaring, to a degree. But these last advances — taking us into the space and information ages — are extremely recent, and space is enormous. If an alien civilization saw us, would we even appear interesting from their perspective? Tayte Taliaferro wants to know, asking: "I was thinking about the projection of light through space. My curtain was open and I...

    There are two reasons, according to Jim Adovasio, we don’t think of baskets or textiles when we think of the Stone Age. One is that stones and bones, being far more durable, are far more common at archeological sites than artifacts made of fiber... And yet it has been around a long time, as four small pieces of clay described by Adovasio this past year make clear. Found at a site called Pavlov in the Czech Republic, they are 27,000 years old--and impressed with patterns that could only have been created by woven fibers. These artifacts push back the date...

    Last March, Chinese researchers announced an ingenious and potentially devastating attack against one of America’s most prized technological assets—a Tesla electric car. The team, from the security lab of the Chinese tech giant Tencent, demonstrated several ways to fool the AI algorithms on Tesla’s car. By subtly altering the data fed to the car’s sensors, the researchers were able to bamboozle and bewilder the artificial intelligence that runs the vehicle. In one case, a TV screen contained a hidden pattern that tricked the windshield wipers into activating. In another, lane markings on the road were ever-so-slightly modified to confuse the...

    More than 2,600 years ago, strange red clouds over Mesopotamia drew the attention of soothsayers across the land. Their royal reports have now helped confine the date of a severe solar storm that washed over the planet. Based on readings of carbon isotopes trapped in tree rings deposited around that time, astronomers already suspected there was a period of intense solar activity around the middle of the 7th century BC... And it seemed like it had pretty far-ranging effects. Earlier in the year, geologists reported similar signs of a storm from around this period in traces of radioactive particles buried...

    ... these documents point to what Anthony Pelosi, a psychiatrist with the UK’s National Health Service in Glasgow and Honorary Professor at the University of Glasgow, calls “one of the worst scientific scandals of all time.” Eysenck is revered as one of the greatest psychologists in history, his fame built on his work concerning intelligence and personality testing, known as psychometrics. He long maintained the hereditability of IQ and personality traits and was a supporter of the work of people like Charles Murray and Richard Herrnstein, the somewhat infamous authors of The Bell Curve, a book that amongst other things...

    Assembly of the Plasma Liner Experiment (PLX) at Los Alamos National Laboratory is well underway with the installation of 18 of 36 plasma guns in an ambitious approach to achieving controlled nuclear fusion (Figure 1). The plasma guns are mounted on a spherical chamber, and fire supersonic jets of ionized gas inward to compress and heat a central gas target that serves as fusion fuel. In the meantime, experiments performed with the currently installed plasma guns are providing fundamental data to create simulations of colliding plasma jets, which are crucial for understanding and developing other controlled fusion schemes. Most fusion...

    Scientists have unearthed new evidence in Greece proving that the island of Naxos was inhabited by Neanderthals and earlier humans at least 200,000 years ago, tens of thousands of years earlier than previously believed. The findings, published today in the journal Science Advances, are based on years of excavations and challenge current thinking about human movement in the region -- long thought to have been inaccessible and uninhabitable to anyone but modern humans. The new evidence is leading researchers to reconsider the routes our early ancestors took as they moved out of Africa into Europe and demonstrates their ability to...

    Those earthquakes were the first major temblors to occur near the Garlock since scientists began taking records decades ago, meaning it's the first time movement -- also known as creeping -- has been detected along the fault line, according to seismologist Zachary Ross. “The Ridgecrest earthquakes initiated this movement on this Garlock Fault," he said. The study found that the sequence increased strain on the 160-mile-long fault, which spans the Mojave Desert and is capable of producing a devastating magnitude 8.0 earthquake. Orbiting radar satellites recently picked up the movement along the Garlock and acquired before and after images of...
