hackingbear shares a report from Popular Science: China Electronics Technology Group Corporation (CETC), China’s foremost military electronics company, announced that its groundbreaking quantum radar has achieved capability of tracking high altitude objects, likely by increasing the coherence time entangled photons. CETC envisions that its quantum radar will be used in the stratosphere to track objects in “the upper atmosphere and beyond” (including space). Quantum can identify the position, radar cross section, speed, direction and even “observe” on the composition of the target such as differentiating between an actual nuclear warhead against inflatable decoys. […] Importantly, attempts to spoof the quantum radar would be easily noticed since any attempt to alter or duplicate the entangled photons would be detected by the radar. The news is an important illustration of a larger trend of Chinese advancement in the new, crucial area of quantum research. Other notable projects in China’s quantum technology include the Micius satellite, and advances by Alibaba and the Chinese University of Science and Technology in a world record of entangling 18 photons (a quantum supercomputer would require about 50 entangled photons), such that China arguably leads the world in quantum technologies.

An anonymous reader quotes a report from The Guardian: The Republic of Ireland will become the world’s first country to sell off its investments in fossil fuel companies, after a bill was passed with all-party support in the lower house of parliament. The state’s 8 billion euro national investment fund will be required to sell all investments in coal, oil, gas and peat “as soon as is practicable”, which is expected to mean within five years. The Irish fossil fuel divestment bill was passed in the lower house of parliament on Thursday and it is expected to pass rapidly through the upper house, meaning it could become law before the end of the year. The Irish state investment fund holds more than 300 million euro in fossil fuel investments in 150 companies. The bill defines a fossil fuel company as a company that derives 20% or more of its revenue from exploration, extraction or refinement of fossil fuels. The bill also allows investment in Irish fossil fuel companies if this funds their move away from fossil fuels. “The [divestment] movement is highlighting the need to stop investing in the expansion of a global industry which must be brought into managed decline if catastrophic climate change is to be averted,” said Thomas Pringle, the independent member of parliament who introduced the bill. “Ireland by divesting is sending a clear message that the Irish public and the international community are ready to think and act beyond narrow short term vested interests.”

After multiple lawsuits have been filed over the butterfly-switch keyboards found on the MacBook Pro and MacBook lineups, you would think Apple would fix this issue by including a keyboard in the new MacBook Pros that can’t be damaged by a little dust. Unfortunately, while the new 2018 MacBook Pro does have an updated third-generation keyboard, Apple tells CNET it doesn’t include any new engineering or tweaks to address the sticky key issue. CNET reports: Instead, the third-generation keyboard’s tweaks are about making it quieter. In a brief typing test, CNET’s long-time MacBook reviewer Dan Ackerman says it isn’t “whisper-quiet” but does “lack the sharp click of the previous design.” Technically, Apple has admitted only that “a smaller percentage of the keyboards in certain MacBook and MacBook Pro models” have demonstrated the sticky key issue. If you buy one, you may likely never have that problem. But it’s worth noting that when the company launched its free keyboard repair program in June, it made literally every single model of MacBook Pro with the “butterfly switch” keyboard eligible.

Sprint on Thursday unveiled a new, more complicated lineup of unlimited mobile data plans. Sprint goes from having one plan starting at $60 per month to four different options costing $50 to $70 a month. “The main price hike hits customers who want to watch streaming video at HD quality instead of being reduced to DVD quality,” reports Fortune. From the report: A new “unlimited plus” plan most resembles the carrier’s current one, with subscribers allowed to use up to 15 GB monthly before experiencing slowed download speeds, receiving HD-quality streaming video, and getting free Hulu and Tidal subscriptions. It costs $70 for one line, rising to $180 for four lines. But Sprint also added a “limited time” promotion that cuts the price to $50 to $100 per month for customers who buy a new phone or bring their own device. A cheaper “unlimited basic” plan, starting at $60 for one line and up to $140 for four lines, slows downloads to 3G speeds after just 500 MB, downgrades streaming to DVD-quality, and offers just a Hulu subscription, but no Tidal account.

Although consumers no longer get cut off or have to pay expensive overage charges when they run through a monthly data allowance, they face an increasing array of restrictions and conditions on all but the most expensive unlimited plans, including slowed download speeds. Sprint’s four-page press release announcing the new plans included 11 footnotes, signaling just how complicated they are.

Mr.Intel writes from a report via Reuters: “Fliers may have a tough time recovering damages for invasive screenings at U.S. airport security checkpoints, after a federal appeals court on Wednesday said screeners are immune from claims under a federal law governing assaults, false arrests and other abuses,” reports Reuters. In a 2-1 vote, the 3rd U.S. Circuit Court of Appeals in Philadelphia said Transportation Security Administration (TSA) screeners are shielded from liability under the Federal Tort Claims Act (FTCA) because they do not function as “investigative or law enforcement officers.” The decision, the first on the issue by a federal appeals court, was a defeat for Nadine Pellegrino, a business consultant from Boca Raton, Florida. “She and her husband had sued for false arrest, false imprisonment and malicious prosecution over a July 2006 altercation at Philadelphia International Airport,” reports Reuters. According to court papers, Pellegrino had been randomly selected for additional screening at the Philadelphia airport before boarding a U.S. Airways flight to Fort Lauderdale, Florida. Pellegrino, then 57, objected to the invasiveness of the search, but conditions deteriorated and she was later jailed for about 18 hours, the papers show. Criminal charges were filed, and Pellegrino was acquitted at a March 2008 trial.

An anonymous reader quotes a report from Space.com: Astronomers have traced a high-energy neutrino to its cosmic source for the first time ever, solving a century-old mystery in the process. Observations by the IceCube Neutrino Observatory at the South Pole and a host of other instruments allowed researchers to track one cosmic neutrino to a distant blazar, a huge elliptical galaxy with a fast-spinning supermassive black hole at its heart. And there’s more. Cosmic neutrinos go hand in hand with cosmic rays, highly energetic charged particles that slam into our planet continuously. So, the new find pegs blazars as accelerators of at least some of the fastest-moving cosmic rays as well. Astronomers have wondered about this since cosmic rays were first discovered, way back in 1912. But they’ve been thwarted by the particles’ charged nature, which dictates that cosmic rays get tugged this way and that by various objects as they zoom through space. Success finally came from using the straight-line journey of a fellow-traveler ghost particle.

On Sept. 22, 2017, […] IceCube picked up another cosmic neutrino. It was extremely energetic, packing about 300 teraelectron volts — nearly 50 times greater than the energy of the protons cycling through Earth’s most powerful particle accelerator, the Large Hadron Collider. Within 1 minute of the detection, the facility sent out an automatic notification, alerting other astronomers to the find and relaying coordinates to the patch of sky that seemed to house the particle’s source. The community responded: Nearly 20 telescopes on the ground and in space scoured that patch across the electromagnetic spectrum, from low-energy radio waves to high-energy gamma-rays. The combined observations traced the neutrino’s origin to an already-known blazar called TXS 0506+056, which lies about 4 billion light-years from Earth. The IceCube team also went through its archival data and found more than a dozen other cosmic neutrinos that seemed to be coming from the same blazar. These additional particles were picked up by the detectors from late 2014 through early 2015. The findings are reported in two separate studies published in the journal Science.
