    Google Revives Controversial Cold-Fusion Experiments
    According to a peer-reviewed paper revealed this week, Google is continuing its experiments into the controversial science of cold fusion -- the theory that nuclear fusion, the process that powers the Sun, can produce energy in a table-top experiment at room temperature. While Google's recent project found no evidence that cold fusion is possible, it did make some advances in measurement and materials-science techniques that the researchers say could benefit energy research. "The team also hopes that its work will inspire others to revisit cold-fusion experiments, even if the phenomenon still fails to materialize," reports Nature. From the report: The Google team explored three experimental set-ups that have been proposed to generate cold fusion -- two involving palladium and hydrogen, and one involving metallic powders and hydrogen. None foundï evidence of fusion. The results have been published across 12 papers over the past 2 years: 9 in peer-reviewed journals and 3ï on the arXiv preprint server. In March 1989, two U.S.-based chemists Stanley Pons and Martin Fleischmann announced that they had seen excess heat and fusion-reaction products -- signs of nuclear fusion -- when they ran a current across two palladium plates in water laden with deuterium, a heavy isotope of hydrogen. Others quickly pointed out errors in their experimental procedure. Since then, two U.S. Department of Energy reviews have found no evidence of the phenomenon . But cold fusion -- now commonly referred to as low-energy nuclear reactions -- has retained a persistent following that continues to claim evidence of success. Google's $10-million project aimed to test the cold-fusion claims rigorously in a field that lacked credible scientific data, says Matthew Trevithick, a research program manager at Google. Another goal was also to push methods in challenging experimental conditions. But, he adds: "The fact that the pay-out could be huge is definitely a component of our interest.

    Samsung's New Chips Support 100W USB-C Fast Charging
    Samsung on Tuesday announced the launch of two new chips that it says will support secure, fast-charging USB-C power delivery controllers. "One of them, the SE8A, is what the company calls the industry's first solution that combines a power delivery controller and Secure Element in a single chip, offering new protections like security key storage," reports BGR. "Another result of the development of these new power delivery controllers is that Samsung's power chargers will now be able to support up to a 100W capacity: A 10x improvement over the 10W of a general smartphone charger." From the report: Samsung said the MM101 supports a symmetric encryption algorithm called the Advanced Encryption Standard that enables product authentication and includes moisture sensing capabilities to ensure safer charging conditions. The SE8A supports USB Type-C Authentication, the certificate-based authentication program for USB-C chargers and devices. "With enhanced security," Samsung explained in the announcement, "the SE8A opens possibilities for new kinds of content and services that may be exclusive to a certain brand, location or event." Today's announcement is also significant because Samsung says the new power delivery controllers meet the most recent USB specs for fast-charging which addresses things like compatibility and efficiency challenges across mobile devices and other electronics. Those challenges can have effects like causing a device to, for example, charge slower than usual in addition to compromising the battery's life cycle.

    iRobot Unveils Roomba S9+ and Braava Jet M6 Robots That Clean Together
    An anonymous reader writes: iRobot today launched two new robots: the Roomba s9+ robot vacuum cleaner and the Braava jet m6 robot mop. The Roomba s9+ robot vacuum with Clean Base Automatic Dirt Disposal starts at $1,299. The Roomba s9 without the Clean Base starts at $999. The Braava jet m6 robot mop starts at $499. All the robots are available for purchase today in the U.S. and Canada. They will start shipping in select European countries on July 12, 2019. The two robots can use iRobot's Imprint Link Technology to "talk to each other" -- vacuuming and then mopping automatically. The technology also works with the Roomba i7+, which launched in September. iRobot is thus introducing two robots that can clean together "as a team." Owners of the robots can initiate a "Linked clean" in the iRobot Home app.

    Intel Graphics Division Shares Wild Futuristic GPU Concept Cards
    MojoKid writes: What do you think graphics cards will look like in the next decade and a half? Intel wanted to know that as well, so it commissioned designer Cristiano Siquiera to give us a taste of what graphics cards might look like in the year 2035. Siquiera, the original talented designer that brought the first set of Intel Odyssey GPU renders not long ago, focused primarily on the fan/shroud designs and what innovations could be fostered in the coming years. He was tasked with thinking far beyond current design conventions, materials and cooling technologies in current-gen graphics cards, and to envision new designs that could employ technologies and materials not even invented yet. One concept, called Gemini, shows an ionic-based cooling system that isn't too far beyond the realm of feasibility. Yet another design, called Prometheus, showcases top edge-mounted display readout that could also be fairly easily employed with flexible OLED display technology. Intel also just launched a new Graphics Command Center driver package today, which offers more customization, better control of power and cooling and one-click game optimization for Intel GPU-enabled systems.
