Grupo Aeromexico SAB is investigating whether a drone slammed into a Boeing Co. 737 jetliner as the aircraft approached its destination in Tijuana, Mexico, on the U.S. border. From a report: Images on local media showed considerable damage to the nose of the 737-800, which was operating Wednesday as Flight 773 from Guadalajara. In a cabin recording, crew members can be heard saying they heard a "pretty loud bang" and asking the control tower to check if the nose was damaged. The collision happened shortly before landing. "The exact cause is still being investigated," Aeromexico said in a statement. "The aircraft landed normally and the passengers' safety was never compromised."

The potential drone strike stoked fears that the rising use of uncrewed aircraft will endanger planes filled with passengers. While most nations prohibit drones from flying in pathways reserved for airliners, the millions of small consumer devices that have been purchased around the world can't be tracked on radar, making it difficult for authorities to enforce the rules. In addition, many users don't know the rules or don't follow them.

A notorious millennial dating practice is starting to creep into the workplace: ghosting. Employers are noticing with increasing frequency that workers are leaving their jobs by simply not showing up and cutting off contact with their companies [Editor's note: the link may be paywalled; syndicated source]. From a report: "A number of contacts said that they had been 'ghosted,' a situation in which a worker stops coming to work without notice and then is impossible to contact," the Federal Reserve Bank of Chicago noted in December's Beige Book, which tracks employment trends. National data on economic "ghosting" is lacking. The term, which usually applies to dating, first surfaced in 2016 on Dictionary.com. But companies across the country say silent exits are on the rise. Analysts blame America's increasingly tight labor market. Job openings have surpassed the number of seekers for eight straight months, and the unemployment rate has clung to a 49-year low of 3.7 percent since September. Janitors, baristas, welders, accountants, engineers -- they're all in demand, said Michael Hicks, a labor economist at Ball State University in Indiana. More people may opt to skip tough conversations and slide right into the next thing.

An anonymous reader shares a report (may be paywalled): Every morning, time once was, a giant roar from Heathrow Airport would announce the departure of flight BA001 to New York. The roar was caused by the injection into the aircraft's four afterburners of the fuel which provided the extra thrust that it needed to take off. Soon afterwards, the pilot lit the afterburners again -- this time to accelerate his charge beyond the speed of sound for the three-and-a-half hour trip to JFK. The plane was Concorde.

Supersonic passenger travel came to an end in 2003. The crash three years earlier of a French Concorde had not helped, but the main reasons were wider. One was the aircraft's Rolls-Royce/Snecma Olympus engines, afterburners and all, which gobbled up too much fuel for its flights to be paying propositions. The second was the boom-causing shock wave it generated when travelling supersonically. That meant the overland sections of its route had to be flown below Mach 1. For the Olympus, an engine optimised for travel far beyond the sound barrier, this was commercial death.

That, however, was then. And this is now. Materials are lighter and stronger. Aerodynamics and the physics of sonic booms are better understood. There is also a more realistic appreciation of the market. As a result, several groups of aircraft engineers are dipping their toes back into the supersonic pool. Some see potential for planes with about half Concorde's 100-seat capacity. Others plan to start even smaller, with business jets that carry around a dozen passengers. The chances of such aircraft getting airborne have recently increased substantially.

A day after hosting a pop-up store in New York City's Bryant Park to explain how privacy is the "foundation of the company," Facebook disclosed that a security flaw potentially exposed the public and private photos of as many as 6.8 million users to developers. From a report: On Friday, the Menlo Park, California-based company said in a blog post that it discovered a bug in late September that gave third-party developers the ability to access users' photos, including those that had been uploaded to Facebook's servers but not publicly shared on any of its services. The security flaw, which exposed photos for 12 days between Sept. 13 and Sept. 25, affected up to 1,500 apps from 876 developers, according to Facebook.

"We're sorry this happened," Facebook said in the post. "Early next week we will be rolling out tools for app developers that will allow them to determine which people using their app might be impacted by this bug. We will be working with those developers to delete the photos from impacted users." Facebook has not yet responded to questions about whether company representatives staffing its privacy pop-ups yesterday were aware of this security flaw as they were meeting with reporters and customers to discuss privacy.

Some YouTube channels are publishing full-length episodes of TV shows, rights of which they obviously do not own, and on top of this, they are trying to crowdfund their piracy efforts by asking viewers to donate some cash. From a report: YouTube creators asking for money is nothing new, be it through the site's built-in membership features or third-party services such as Patreon. But trying to profit off someone else's intellectual property isn't the same as asking for support on an original video they've created. The person who runs the Kitchen Nightmares Hotel Hell and Hell's Kitchen channel did not respond to multiple requests for comment from Engadget, but their Patreon page (named YoIUploadShows) isn't coy.

"Hey! It's not as easy as you might think to make my content, I have to look for the best quality episodes I can find, download them, convert them, edit them, render them and upload them," YoIUploadShows' Patreon page reads. "This can sometimes take at least a few hours. Especially because the downloads are usually slow and the rendering itself can take a couple hours, because I started making all my uploads in HD instead of 480p to give them a little extra clarity." It's not easy, folks, so for that he or she "would really appreciate the extra support if you have any money to spare :)"

Chinese hackers are breaching Navy contractors to steal everything from ship-maintenance data to missile plans, triggering a top-to-bottom review of cyber vulnerabilities, WSJ reported Friday, citing officials and experts. From the report: A series of incidents in the past 18 months has pointed out the service's weaknesses, highlighting what some officials have described as some of the most debilitating cyber campaigns linked to Beijing. Cyberattacks affect all branches of the armed forces but contractors for the Navy and the Air Force are viewed as choice targets for hackers seeking advanced military technology, officials said. Navy contractors have suffered especially troubling breaches over the past year, one U.S. official said. The data allegedly stolen from Navy contractors and subcontractors often is highly sensitive, classified information about advanced military technology, according to U.S. officials and security researchers. The victims have included large contractors as well as small ones, some of which are seen as lacking the resources to invest in securing their networks. One major breach of a Navy contractor, reported in June, involved the theft of secret plans to build a supersonic anti-ship missile planned for use by American submarines, according to officials.

An anonymous reader writes: Plenty of high-tech electronic components, like solar panels, rechargeable batteries, and complex circuits require specific rare metals. These can include magnetic neodymium, electronic indium, and silver, along with lesser-known metals like praseodymium, dysprosium, and terbium. These metals are mined in large quantities in countries around the world, and they make their way into the supply chains of all sorts of electronics and renewables companies.

A group of researchers from the Dutch Ministry of Infrastructure determined how many of these important metals will be required by 2050 in order to make enough solar panels and wind turbines to effectively combat climate change. With plenty of countries, states, cities, and companies pledging to go 100 percent renewable by 2050, the number of both solar panels and wind turbines is expected to skyrocket. According to the analysis, turbines and solar panels might be skyrocketing a bit too much. Demand for some metals like neodymium and indium could grow by more than a dozen times by 2050, and there simply might not be enough supply to power the green revolution.

Imax is making its exit from virtual reality (VR) official: The company notified shareholders with a SEC filing this week that it will close down its remaining three VR centers, and write off "certain VR content investments." From a report: A company spokesperson confirmed the planned closures and shared the following statement with Variety: "With the launch of the IMAX VR centre pilot program our intention was to test a variety of different concepts and locations to determine which approaches work well. After a trial period with VR centres in multiplexes, we have decided to conclude the IMAX VR centre pilot program and close the remaining three locations in Q1 2019."

The company previously closed four of its seven VR centers, including most recently its sole European outpost in Manchester. Imax launched Imax VR in early 2017 with a flagship location adjacent to the Grove mall in Los Angeles. At the time, the expansion into VR was billed as an experiment, and a way for Imax to determine whether VR could be the next big thing for the company. [...] Imax also set up a $50 million VR content fund, and got CAA, China Media Capital, and the Raine Group to co-produce VR experiences. Further reading: The virtual reality dream is dying.

A week after releasing v5.0 major update, WordPress has pushed the first security patch for its popular CMS service. ZDNet: Released hours ago, WordPress version 5.0.1 fixes seven security vulnerabilities (some of which allow site takeover) but also plugs a pretty serious privacy leak. The latter was found by the authors of the popular Yoast SEO plugin, who discovered that in some cases the activation screen for new users could end up being indexed by Google. With specially crafted Google searches, an attacker could find these pages and collect users' email addresses, and in some rare cases, default-generated passwords. This leak could have catastrophic consequences if the user has an admin role or if the user didn't change his default password, as is regularly advised.

A corporate-issued laptop lifted from a Lenovo employee in Singapore contained a cornucopia of unencrypted payroll data on staff based in the Asia Pacific region, news outlet The Register reports. From the report: Details of the massive screw-up reached us from Lenovo staffers, who are simply bewildered at the monumental mistake. Lenovo has sent letters of shame to its employees confessing the security snafu. "We are writing to notify you that Lenovo has learned that one of our Singapore employees recently had the work laptop stolen on 10 September 2018," the letter from Lenovo HR and IT Security, dated 21 November, stated.

"Unfortunately, this laptop contained payroll information, including employee name, monthly salary amounts and bank account numbers for Asia Pacific employees and was not encrypted." Lenovo employs more than 54,000 staff worldwide, the bulk of whom are in China.

An anonymous reader quotes a report from The Guardian: Journalists working as factcheckers for Facebook have pushed to end a controversial media partnership with the social network, saying the company has ignored their concerns and failed to use their expertise to combat misinformation. Current and former Facebook factcheckers told the Guardian that the tech platform's collaboration with outside reporters has produced minimal results and that they've lost trust in Facebook, which has repeatedly refused to release meaningful data about the impacts of their work. Some said Facebook's hiring of a PR firm that used an antisemitic narrative to discredit critics -- fueling the same kind of propaganda factcheckers regularly debunk -- should be a deal-breaker.

Facebook now has more than 40 media partners across the globe, including the Associated Press, PolitiFact and the Weekly Standard, and has said false news on the platform is "trending downward." While some newsroom leaders said the relationship was positive, other partners said the results were unclear and that they had grown increasingly resentful of Facebook. Facebook has said that third-party factchecking is one part of its strategy to fight misinformation, and has claimed that a "false" rating leads an article to be ranked lower in news feed, reducing future views by 80% on average. The company has refused, however, to publicly release any data to support these claims. Facebook said in a statement that it had "heard feedback from our partners that they'd like more data on the impact of their efforts," adding that it has started sending "quarterly reports" with "customized statistics" to partners and would be"looking for more statistics to share externally in early 2019." Facebook declined to share the reports with the Guardian.

NASA's Juno mission to the gas giant Jupiter has reached its halfway mark and has revealed new views of cyclones at the poles. The BBC reports: As it orbits the planet every 53 days - Juno performs a science-gathering dive, speeding from pole to pole. Its sensors take measurements of the composition of the planet, in an effort to decipher how the largest world in our Solar System formed. Mapping the magnetic and gravity fields should also expose Jupiter's structure.

But images from JunoCam -- a camera that was intended to capture images that could be shared with the public -- has already given us some surprising insights. "When we made our first pass over the poles, we knew we were seeing a territory on Jupiter we had never seen before," said Dr Candice Hansen, from the Planetary Science Institute in Arizona. "What we did not expect was that we would see these orderly polygons of cyclones; huge storms - twice the size of Texas."

"The Register has an article on the possibility that a supernova or a series of them could explain a mass die-off of marine animals around 2.6 million years ago," writes Slashdot reader KindMind. From the report: A gigantic supernova explosion may have triggered mass extinctions for creatures living in Earth's prehistoric oceans some 2.6 million years ago, according to new research published in Astrobiology. Marine animals like the megalodon [...] suddenly disappeared during the late Pliocene. Around the same time, scientists [...] noticed a peak in the iron-60 isotope in ancient seabeds. "As far back as the mid-1990s, people said, "Hey, look for iron-60. It's a telltale because there's no other way for it to get to Earth but from a supernova.' Because iron-60 is radioactive, if it was formed with the Earth it would be long gone by now. So, it had to have been rained down on us" explained Adrian Melott, lead author of the paper and a physics and astronomy professor at the University of Kansas.

The team believes that a supernova located 150 light years away set of a chain of supernovae bursts and covered the Earth in a shroud of deadly cosmic ray radiation. This was amplified, Melott said, because the Solar System is right on the edge of an area of the interstellar medium called the Local Bubble. The Local Bubble extends about 300 light years across and contains the two main clouds of dust and gas: Local Interstellar Cloud and the G-Cloud. As the supernovae ejected cosmic rays, these beams of energetic particles would have repeatedly bounced off the clouds to create a "cosmic-ray bath" that could have lasted 10,000 to 100,000 years. Some of that radiation such as cosmic ray muons would have leaked onto Earth, and over time it could have led to genetic mutations and cancers [that would have caused animals like the megalodon to die off prematurely].

An anonymous reader quotes a report from The Guardian: Surgical instruments used in brain operations should be treated to ensure they are not contaminated with proteins linked to Alzheimer's disease, according to scientists who found evidence that they may be spread by certain medical procedures. The researchers urged doctors to decontaminate neurosurgical tools more thoroughly as a precautionary measure to reduce the potential risk of spreading abnormal proteins known to build up in the brains of Alzheimer's patients. Prof John Collinge, director of the Medical Research Council prion unit at University College London, said that while Alzheimer's disease was not contagious, there was a slim risk that harmful proteins that drive the disease could spread through brain surgery and other rare procedures.

schwit1 shares a report from The Times: It will shake houses and tall buildings, and unleash a 100ft tsunami on one of the most densely populated and industrialized coastlines in the world. It could kill and injure close to a million people. It will almost certainly come in the next few decades. Now, the Japanese government is making plans to evacuate millions of people in anticipation of what could be one of the worst natural disasters in history (Warning: source may be paywalled; alternative source). It is known as the Nankai Trough megaquake. The Japanese government has previously estimated that there is a 70 to 80 percent chance that such an event will take place in the next 30 years and that the earthquake, and subsequent tsunami, could kill 323,000 people and injure 623,000. Unfortunately, the report doesn't outline how the government plans to get people out of harm's way. The city with the most people in the danger zone is Nagoya, Japan's fourth largest city and home to 2.3 million people. "The home of the nation's industry Hamamatsu is also at risk and home to over 800,000 people," reports The Irish Sun.
