The discovery of “non-equilibrium matter” could re-write the rules of physics. Long-time Slashdot reader jasonbrown quotes ScienceAlert: For months now, there’s been speculation that researchers might have finally created time crystals — strange crystals that have an atomic structure that repeats not just in space, but in time, putting them in perpetual motion without energy. Now it’s official — researchers have just reported in detail how to make and measure these bizarre crystals. And two independent teams of scientists claim they’ve actually created time crystals in the lab based off this blueprint, confirming the existence of an entirely new form of matter. Both teams — one at Harvard and the other at the University of Maryland — have submitted their findings to peer-reviewed publications, according to the article, and “the fact that two separate teams have used the same blueprint to make time crystals out of vastly different systems is promising.” Read more of this story at Slashdot.

An anonymous reader quotes a report from Ars Technica: In 1935, scientists predicted that the simplest element, hydrogen, could also become metallic under pressure, and they calculated that it would take 25 GigaPascals to force this transition (each Gigapascal is about 10, 000 atmospheres of pressure). That estimate, in the words of the people who have finally made metallic hydrogen, “was way off.” It took until last year for us to reach pressures where the normal form of hydrogen started breaking down into individual atoms — at 380 GigaPascals. Now, a pair of Harvard researchers has upped the pressure quite a bit more, and they have finally made hydrogen into a metal. All of these high-pressure studies rely on what are called diamond anvils. This hardware places small samples between two diamonds, which are hard enough to stand up to extreme pressure. As the diamonds are forced together, the pressure keeps going up. Current calculations suggested that metallic hydrogen might require just a slight boost in pressure from the earlier work, at pressures as low as 400 GigaPascals. But the researchers behind the new work, Ranga Dias and Isaac Silvera, discovered it needed quite a bit more than that. In making that discovery, they also came to a separate realization: normal diamonds weren’t up to the task. “Diamond failure, ” they note, “is the principal limitation for achieving the required pressures to observe SMH, ” where SMH means “solid metallic hydrogen” rather than “shaking my head.” The team came up with some ideas about what might be causing the diamonds to fail and corrected them. One possibility was surface defects, so they etched all diamonds down by five microns to eliminate these. Another problem may be that hydrogen under pressure could be forced into the diamond itself, weakening it. So they cooled the hydrogen to slow diffusion and added material to the anvil that absorbed free hydrogen. Shining lasers through the diamond seemed to trigger failures, so they switched to other sources of light to probe the sample. After loading the sample and cranking up the pressure (literally — they turned a handcrank), they witnessed hydrogen’s breakdown at high pressure, which converted it from a clear sample to a black substance, as had been described previously. But then, somewhere between 465 and 495 GigaPascals, the sample turned reflective, a key feature of metals The study has been published in the journal Science. Read more of this story at Slashdot.

It appears Apple is filtering and censoring bad reviews of the LG’s UltraFine 5K display. From a report on The Next Web: The deletion was first spotted by a Reddit user four days ago. Though it’s possible the reviews were removed for some other reason, at first glance, it looks like censorship. It’s not a good look for the company. Apple said it was getting out of the monitor business, and instead chose to work more closely with third-party partners, heavily featuring LG’s 5K and 4K UltraFine displays at its recent MacBook Pro unveiling. But then the monitor received multiple negative reviews from users who were experiencing issues such as the screen failing to wake up from sleep. The Reddit post also points out that: “In many cases, attempts to fix the problem through physical reconnection[sic] of the monitor, or manual restarts, have caused the attached Mac to crash, become otherwise unresponsive, or develop problems with the touch bar (where equipped).” Read more of this story at Slashdot.

China, the world’s second largest economy, is pouring 1.5 billion yuan ($168 million) into a program aimed at making it rain in its usually arid northwestern region. From a report: No stranger to using technologies like cloud seeding to influence and even control weather patterns, China’s top economic planners recently gave the go ahead for what will be one of the country’s largest weather-modification projects, reports the South China Morning Post. According to the Post, a feasibility study by the country’s meteorological agency concluded that the three-year program could see a rise in precipitation over an area of 960, 000 sq km, or as much as 10% of the country’s landmass. The multi-million dollar budget allocated by the National Development and Reform Commission will reportedly cover the cost for four new aircraft and updates to eight existing planes, nearly 900 rocket launch systems and over 1, 800 digital control devices.

China Is Splashing $168 Million To Make It Rain
An anonymous reader quotes a report from The Guardian: Libraries in St Louis have been bought to a standstill after computers in all the city’s libraries were infected with ransomware, a particularly virulent form of computer virus used to extort money from victims. Hackers are demanding $35, 000 (£28, 000) to restore the system after the cyberattack, which affected 700 computers across the Missouri city’s 16 public libraries. The hackers demanded the money in electronic currency bitcoin, but, as CNN reports, the authority has refused to pay for a code that would unlock the machines. As a result, the library authority has said it will wipe its entire computer system and rebuild it from scratch, a solution that may take weeks. On Friday, St Louis public library announced it had managed to regain control of its servers, with tech staff continuing to work to restore borrowing services. The 16 libraries have all remained open, but computers continue to be off limits to the public. Spokeswoman Jen Hatton told CNN that the attack had hit the city’s schoolchildren and its poor worst, as many do not have access to the internet at home. “For many we’re their only access to the internet, ” she said. “Some of them have a smartphone, but they don’t have a data plan. They come in and use the wifi.” As well as causing the loans system to seize up, preventing borrowers from checking out or returning books, the attack froze all computers, leaving no one able to access the four million items that should be available through the service. The system is believed to have been infected through a centralized computer server, and staff emails have also been frozen by the virus. The FBI has been called in to investigate.

“Any student progress from 9:19 to 10:33 a.m. on Friday was not saved…” explained the embarrassed CTO of the educational non-profit Code.org, “and unfortunately cannot be recovered.” Slashdot reader theodp writes: Code.org CTO Jeremy Stone gave the kids an impromptu lesson on the powers of two with his explanation of why The Cloud ate their homework. “The way we store student coding activity is in a table that until today had a 32-bit index… The database table could only store 4 billion rows of coding activity information [and] we didn’t realize we were running up to the limit, and the table got full. We have now made a new student activity table that is storing progress by students. With the new table, we are switching to a 64-bit index which will hold up to 18 quintillion rows of information. The issue also took the site offline, temporarily making the work of 16 million K-12 students who have used the nonprofit’s Code Studio disappear. “On the plus side, this new table will be able to store student coding information for millions of years, ” explains the site’s CTO. But besides Friday’s missing saves, “On the down side, until we’ve moved everything over to the new table, some students’ code from before today may temporarily not appear, so please be patient with us as we fix it.” Read more of this story at Slashdot.

Billions of robocalls came from two groups selling extended auto warranties, SEO services, and home security systems over the last seven years — many to numbers on the “Do Not Call” list — but this week the Federal Trade Commission took action. Trailrunner7 shares this report from OnTheWire: Continuing its campaign against phone fraud operations, the FTC has dismantled two major robocall organizations… They and many of their co-defendants have agreed to court-ordered bans on robocall activities and financial settlements… The FTC and the FCC both have been cracking down on illegal robocall operations recently. The FCC has formed a robocall strike force with the help of carriers and also has signed an agreement to cooperate with Canadian authorities to address the problem. “The law is clear about robocalls, ” says one FTC executive. “If a telemarketer doesn’t have consumers’ written permission, it’s illegal to make these calls.” Read more of this story at Slashdot.
