The Grim Reefer shares a report from Live Science: For the first time, scientists have created a permanently magnetic liquid. These liquid droplets can morph into various shapes and be externally manipulated to move around, according to a new study. Thomas Russell, a distinguished professor of polymer science and engineering at the University of Massachusetts Amherst, and his team created these liquid magnets by accident while experimenting with 3D printing liquids at the Lawrence Berkeley National Laboratory (where Russell is also a visiting faculty scientist). The goal was to create materials that are solid but have characteristics of liquids for various energy applications.

One day, postdoctoral student and lead author Xubo Liu noticed 3D-printed material, made from magnetized particles called iron-oxides, spinning around in unison on a magnetic stir plate. So when the team realized the entire construct, not just the particles, had become magnetic, they decided to investigate further. Using a technique to 3D-print liquids, the scientists created millimeter-size droplets from water, oil and iron-oxides. The liquid droplets keep their shape because some of the iron-oxide particles bind with surfactants -- substances that reduce the surface tension of a liquid. The surfactants create a film around the liquid water, with some iron-oxide particles creating part of the filmy barrier, and the rest of the particles enclosed inside, Russell said. The team then placed the millimeter-size droplets near a magnetic coil to magnetize them. But when they took the magnetic coil away, the droplets demonstrated an unseen behavior in liquids -- they remained magnetized. (Magnetic liquids called ferrofluids do exist, but these liquids are only magnetized when in the presence of a magnetic field.) A video of the new material has been posted to YouTube. The researchers say their findings could lead to a revolutionary class of printable liquid devices for a variety of applications from artificial cells that deliver targeted cancer therapies to flexible liquid robots that can change their shape to adapt to their surroundings.

After a developer based in the Crimea region of Ukraine was blocked from GitHub this week, the Microsoft-owned software development platform said it has started restricting accounts in countries facing U.S. trade sanctions. GitHub lists Crimea, Cuba, Iran, North Korea, and Syris as countries facing U.S. sanctions. ZDNet reports: As the developer reports, his website https://tkashkin.tk, which is hosted on GitHub, now returns a 404 error. He also can't create new private GitHub repositories or access them. While his website could easily be moved to another hosting provider, the block does pose a challenge for his work on GameHub, which has an established audience on GitHub.

GitHub does offer developers an appeal form to dispute restrictions but [the developer] told ZDNet that, at this point, there's nothing to gain by appealing the restriction. "It is just pointless. My account is flagged as restricted and, in order to unflag it, I have to provide a proof that I don't live in Crimea. I am in fact a Russian citizen with Crimean registration, I am physically in Crimea, and I am living in Crimea my entire life," he said. "For individual users, who are not otherwise restricted by U.S. economic sanctions, GitHub currently offers limited restricted services to users in these countries and territories. This includes limited access to GitHub public repository services for personal communications only," it says.

GitHub notes on its page about U.S. trade controls that its paid-for on-premise software -- aimed to enterprise users -- may be an option for users in those circumstances. "Users are responsible for ensuring that the content they develop and share on GitHub.com complies with the U.S. export control laws, including the EAR (Export Administration Regulations) and the U.S. International Traffic in Arms Regulations (ITAR)," GitHub says. "The cloud-hosted service offering available at Github.com has not been designed to host data subject to the ITAR and does not currently offer the ability to restrict repository access by country. If you are looking to collaborate on ITAR- or other export-controlled data, we recommend you consider GitHub Enterprise Server, GitHub's on-premises offering."

An anonymous reader quotes a report from The Verge: A new report from The Wall Street Journal shares some of the proposals for Saudi Arabia's biggest megaproject yet: a city built in the desert named Neom, where robots will outnumber humans and hologram teachers will educate genetically-enhanced students. These are only proposals, of course, dreamt up by American consulting firms like McKinsey and Boston Consulting who have no incentive to bring Saudi leaders down to Earth. But all the same, they give you a flavor of what trillions of dollars of oil wealth will do to your sense of proportion.

The whole Neom project is undeniably fascinating. It was first announced in 2017, with Saudi Arabia's de-facto leader, Crown Prince Mohammed bin Salman, saying he wants the city to attract the "world's greatest minds and best talents." According to planning documents reported by the WSJ, bin Salman "envisions Neom the largest city globally by GDP, and wanted to understand what he can get with up to 500 billion USD investment." The project is the flagpole of Saudi Arabia's plans to diversify the country's economy away from oil. MBS and other Saudi leaders known this source of revenue can't last forever, and they're keen to develop cities like Neom as new commercial hubs. As currently planned, Neom will occupy a region the size of Massachusetts. This will include a huge coastal urban sprawl; outlying towns and villages; advance manufacturing hubs in industries like biotech and robotics; and links with international shipping routes. Early building work has already begun, with facilities including a new airport and palace. Some of the key features of the city include cloud seeding to make it rain, dystopian surveillance to keep citizens safe, genetic engineering to increase human strength and IQ, robot cage fights and "maids," flying taxis, and even a fake moon that could perhaps be created by a fleet of drones or via live-streaming images from space.

The report notes that it's anyone's guess as to whether Neom will live up to its planners' dreams. What may hinder its success is Saudi Arabia's corruption, difficult legal system, and unappealing social norms. "Alcohol is banned; women's rights are restricted; and homosexuality is illegal," the report notes. There's also the sweltering weather that'll only get worse with climate change.

McGruber shares a report from NBC News: In January, two San Diego businessmen launched a company, ScootScoop, that impounds e-scooters at the behest of private property owners. The company already has 4,500 of the e-scoooters packed in warehouses and garages. Most of the scofflaws pay their bounty, but a few of the half dozen or so e-scooter companies active in San Diego aren't on board. ScootScoop charges the companies $30 to release each e-scooter. Its freelance workers will also move or stand up a scooter that's blocking walkways or roads. The cost to the scooter firms is $3 to $5. ScootScoop contractors take photos to show their homework. ScootScoop is also developing an app where San Diego business owners can drop a pin on a map to alert the "scoopers" to an interloper that needs to be impounded within 24 hours. The pair also hopes to go global by using a model whereby satellite operators pay licensing fees. They say they've already had inquiries from entrepreneurs in Mexico and Australia.

The duo behind ScootScoop says their business shouldn't be so urgent. At least some of the e-scooter companies' user agreements specify fines as much as $150 for leaving the devices in forbidden zones, including on private property. But they say the rules aren't enforced by the firms for fear of slowing explosive market growth. Some e-scooter companies have threatened to sue ScootScoop, but so far none have filed complaints. "The community should be careful when engaging with pop-up companies claiming to provide city services like impounding or towing," Lime Electric Scooter Rentals spokeswoman Mary Caroline Pruitt said via email. "Impounding bikes or scooters requires compliance with the California Vehicle Code, and Lime is in the process of reviewing whether these pop-ups are committing violations which may subject them to liability."

MojoKid writes: AMD's new Ryzen 3000 processors can boost as high as 4.6 GHz, a notable bump over previous Ryzen models, but what about AMD's purported Instructions Per Cycle (IPC) gains? Has AMD's Zen 2 architecture finally caught up to Intel's Coffee Lake-based Core series processors in terms of IPC? To prove this out, HotHardware pitted a 12-core Ryzen 9 3900X against Intel's 8-core Core i9-9900K in an array of tests, with both chips locked at 4GHz across all cores and four of the Ryzen CPU cores (or 2 CCXs) disabled (save for a couple of instances to show MT scaling). This allowed AMD's fastest Zen 2-based CPU, with its full 64MB L3 cache complement, to compete against Intel's current fastest desktop chip at identical clock speeds. A series of single-threaded benchmarks were run, in addition to some standard games tests, which are lightly multithreaded. The Intel and AMD multi-core processors essentially traded blows across a number of tests, but Intel won more often than not. The blue team notched IPC wins in SANDRA's Dhrystone integer tests, Geekbench, POV-Ray, LAME MT, and the gaming tests. AMD stole single-threaded victories in SANDRA's Whetstone FPU tests, Cinebench, and Y-Cruncher. While not an outright win for AMD, the company has obviously worked hard to improve 3rd Gen Ryzen IPC throughput, while its multi-core scaling is downright impressive.

An anonymous reader quotes a report from CNBC: In a tweet on Friday, President Trump said his administration will not grant Apple any relief on Mac Pro parts made in China. "Apple will not be given Tariff wavers (sic), or relief, for Mac Pro parts that are made in China," President Trump said. "Make them in USA, no Tariffs!" Apple asked for waivers on tariffs on the Mac Pro. Apple said it wanted to be exempt on some parts it uses for the new Mac Pro, including a power supply unit, the stainless-steel enclosure, finished mice and trackpads and circuit boards. "There are no other sources for this proprietary, Apple-designed component," Apple said in a filing. Apple shifted production of the Mac Pro to China in June, saving shipping costs for components that are supplied near Shanghai.

The Justice Department approved T-Mobile's acquisition of Sprint, a deal it rejected under the previous administration, clearing one of the biggest hurdles to a takeover that will reshape the wireless industry. From a report: T-Mobile and Sprint agreed to sell multiple assets to Dish Network as a condition for approval, paving the way to creating a new wireless company, the Justice Department said in a statement Friday. The carriers have promised to deploy a 5G network that would cover 97% of the U.S. population within three years and 99% within six years. "The remedies set up Dish as a disruptive force in wireless," said Makan Delrahim, the head of the Justice Department's antitrust division, during a briefing with reporters.

Alex Hern, reporting for The Guardian: Apple contractors regularly hear confidential medical information, drug deals, and recordings of couples having sex, as part of their job providing quality control, or "grading," the company's Siri voice assistant, the Guardian has learned. Although Apple does not explicitly disclose it in its consumer-facing privacy documentation, a small proportion of Siri recordings are passed on to contractors working for the company around the world.

They are tasked with grading the responses on a variety of factors, including whether the activation of the voice assistant was deliberate or accidental, whether the query was something Siri could be expected to help with and whether Siri's response was appropriate. Apple says the data "is used to help Siri and dictation ... understand you better and recognise what you say." [...] Apple told the Guardian: "A small portion of Siri requests are analysed to improve Siri and dictation. User requests are not associated with the user's Apple ID. Siri responses are analysed in secure facilities and all reviewers are under the obligation to adhere to Apple's strict confidentiality requirements." The company added that a very small random subset, less than 1% of daily Siri activations, are used for grading, and those used are typically only a few seconds long."

An anonymous reader writes: Marcus 'MalwareTech' Hutchins, the security researcher who helped stop the WannaCry ransomware outbreak, was sentenced today in the US to time served and one year of supervised release. The UK-born malware analyst avoided the prison time in the case as the judge described "too many positives on other side of ledger" -- referring to Hutchins' role in the WannaCry ransomware outbreak and his work as a malware analyst. Judge J. P. Stadmueller had a difficult decision on his hand, and would have considered a pardon. However, courts have no such power, and deferred to the executive branch. In court, Hutchins apologized, again, to victims, family, and friends. The judge waived any fines. The sentence comes after Hutchins pleaded guilty this April on two charges of entering a conspiracy to create and distribute malware, and in aiding and abetting its distribution.

Japan's SoftBank Group unveiled a second technology megafund even bigger than its nearly $100 billion Vision Fund, answering skeptics who questioned whether anyone could raise so much in such a short time. From a report: Vision Fund 2, as the company is calling it, expects to gather some $108 billion in capital from more than a dozen investors that have signed memorandums of understanding, ranging from Apple, and Microsoft to Kazakhstan's sovereign-wealth fund, SoftBank said Friday. Some $38 billion of that capital will come from SoftBank itself, funded by proceeds from the first Vision Fund.

Other investors including Goldman Sachs Group are in active talks to invest, people familiar with the matter said Thursday, and the fund's size is likely to grow. [...] The planned inauguration of the second fund is a victory for SoftBank Chief Executive Masayoshi Son, who started the first Vision Fund just two years ago amid widespread doubt about its viability.

People on the receiving end of addled smartphone navigation deal with the lost; 'Somebody backed into our mailboxes.' From a report: Everett Ogden's dream house was a three-bedroom at the end of a quiet dead-end road along a river in Jacksonville, Fla. It wasn't long after moving in about a year ago that the strangers started to pull up, sometimes eight a day. The driveway is narrow, so they often do U-turns on the lawn and sometimes run over the sprinklers. "Just yesterday," said Mr. Ogden, 42, "somebody backed into our mailboxes." Drivers have made news for relying too much on navigation apps like those from Alphabet's Google Maps and Apple's maps app. They've driven onto airport runways, through muddy fields, into lakes. Then there are the other victims of addled navigation, those living on the receiving end of ill-conceived directions the algorithms deal out.

Mr. Ogden, who works in sales, spent time with Google Maps and cracked the issue: When people wanted to travel from town to streets in a nearby naval base, the mapping service routed them through Mr. Ogden's lot. He made a spreadsheet, and "there were 47 different streets that would point to our house." He reported them to Google and 20 were fixed, he said. Google said it is working to resolve Mr. Ogden's routes. [...] Google Maps and Apple Maps have support pages and app functions that let users submit edits to directions for review. Some users say corrections can take months to be approved, if they're accepted at all. Residents sometimes must take matters into their own hands.

Despite a rare confluence of commercial forces and scientific interest, generating new hair remains outside the realm of the possible. This could be changing, though -- and not owing to new packaging of the same old medicines. From a report: Recently a series of scientific publications has explored advances that involve both stem-cell research and 3-D printing, with the goal of cloning a person's actual hair and then inserting it into his or her scalp -- in tremendous, unlimited quantities. "For a long time, we've been saying this is 10 years away," says Robert Bernstein, a dermatologist in Manhattan who specializes in hair transplantation. "But now it actually might be less." Of all the parts of the body to create in a lab, hair could seem like the simplest. It's a strand of protein filaments wrapped around one another. Hair doesn't have to "function" in the way of a liver or brain; it just has to sit around and grow and not fall out.

But hair is much more complex to make than many researchers initially expected. To produce a single, hardy strand, the body relies on thousands of stem cells called dermal papillae at the base of each hair follicle. Human scalps contain about 100,000 hair follicles, but their life spans are limited: As dermal papillae disappear over time, follicles "miniaturize" and become dormant. When a hair follicle goes dormant, it cannot be restored. [...] The answer, then, lies in generating new hair. This science is progressing alongside the creation of other bodily structures in what is known as cell therapy, a promising area of medicine in which therapies are derived from a person's own stem cells. Pancreatic cells could replace those that stopped producing insulin in people with type 1 diabetes. Immune cells could be used to attack tumors. Nerve cells could be used to repair spinal-cord injuries. And, of course, hair follicles could be used to cover hairless skin. Using cells from a person's own body minimizes the risk that the immune system will reject the hair transplants. The ultimate goal among scientists is to create "hair farms," as the entrepreneur Geoff Hamilton and others put it.

The majority of YouTube videos about the climate crisis oppose the scientific consensus and "hijack" technical terms to make them appear credible, a new study has found. From a report: Researchers have warned that users searching the video site to learn about climate science may be exposed to content that goes against mainstream scientific belief. Dr Joachim Allgaier of RWTH Aachen University in Germany analysed 200 YouTube videos to see if they adhered to or challenged the scientific consensus. To do so, he chose 10 search terms: Chemtrails, climate, climate change, climate engineering, climate hacking, climate manipulation, climate modification, climate science, geoengineering, and global warming.

The videos were then assessed to judge how closely they adhered to the scientific consensus, as represented by the findings of reports by UN Intergovernmental Panel on Climate Change (IPCC) from 2013 onwards. These concluded that humans have been the "dominant cause" of global warming since the 1950s. However, Allgaier found that the message of 120 of the top 200 search results went against this view.

An anonymous reader shares a report: For the better part of two years, the folks at Mozilla have been diligently chipping away at Mozilla WebThings, an open implementation of the World Wide Web Consortium's (W3C) Web of Things standard for monitoring and controlling connected devices. In April, it gained a number of powerful logging, alarm, and networking features, and this week, a revamped component of WebThings -- WebThings Gateway, a privacy- and security-focused software distribution for smart home gateways -- formally debuted. Experimental builds of WebThings Gateway 0.9 are available on GitHub for the Turris Omnia router, with expanded support for routers and developer boards to come down the line. (Separately, there's a new build compatible with the recently announced Raspberry Pi 4.) Mozilla notes that it currently only offers "extremely basic" router configuration and cautions against replacing existing firmware, but the company says that it's a noteworthy milestone in its path to creating a full software distribution for wireless routers.

Beverage firm Long Island Iced Tea -- now known as Long Blockchain -- is being investigated by the U.S. Federal Bureau of Investigation for insider trading and securities fraud. From a report: Court records show that the FBI is investigating suspicious dealings that date back to December 2017 -- around the time when the beverage company changed its name and shifted its "primary corporate focus" from selling sweetened iced tea to blockchain. The company's stock shot up by almost 300 percent after it announced the pivot in late 2017. The FBI is focusing in on secretive phone message conversations about Long Island Iced Tea between two men, Oliver Lindsay and Gannon Giguiere, who were previously arrested for securities fraud related to a different company.

Alphabet's autonomous driving and robotaxi company Waymo teamed up with fellow Alphabet company and AI specialist DeepMind to develop new training methods that would help makes its training better and more efficient. TechCrunch reports: The two worked together to bring a training method called Population Based Training (PBT for short) to bear on Waymo's challenge of building better virtual drivers, and the results were impressive -- DeepMind says in a blog post that using PBT decreased by 24% false positives in a network that identifies and places boxes around pedestrians, bicyclists and motorcyclists spotted by a Waymo vehicle's many sensors. Not only that, but is also resulted in savings in terms of both training time and resources, using about 50% of both compared to standard methods that Waymo was using previously.

What DeepMind and Waymo did with this experiment was essentially automate killing the "bad" training and replacing them with better-performing spin-offs of the best-in-class networks running the task. That's where evolution comes in, since it's kind of a process of artificial natural selection. Yes, that does make sense -- read it again. In order to avoid potential pitfalls with this method, DeepMind tweaked some aspects after early research, including evaluating models on fast, 15-minute intervals, building out strong validation criteria and example sets to ensure that tests really were building better-performing neural nets for the real world, and not just good pattern-recognition engines for the specific data they'd been fed. Finally, the companies also developed a sort of "island population" approach by building sub-populations of neural nets that only competed with one another in limited groups, similar to how animal populations cut off from larger groups (i.e. limited to islands) develop far different and sometimes better-adapted characteristics versus their large land-mass cousins.

France announced plans on Thursday to develop satellites armed with laser weapons that will be used against enemy satellites that threaten the country's space forces. Popular Mechanics reports: In remarks earlier today, French Defense Minister Florence Parly said, "If our satellites are threatened, we intend to blind those of our adversaries. We reserve the right and the means to be able to respond: that could imply the use of powerful lasers deployed from our satellites or from patrolling nano-satellites." "We will develop power lasers, a field in which France has fallen behind," Parly added.

France also plans to develop nano-satellite patrollers -- small satellites that act as bodyguards for larger French space assets by 2023. Per Parly's remarks, nano-sats could be armed with lasers. According to DW, France is also adding cameras to new Syracuse military communications satellites. Additionally France plans to set up its own space force, the "Air and Space Army," as part of the French Air Force. The new organization will be based in Toulouse, but it's not clear if the Air and Space Army will remain part of the French Air Force or become its own service branch.

Louisiana Governor John Bel Edwards has activated a state-wide state of emergency in response to a wave of ransomware infections that have hit multiple school districts. ZDNet reports: The ransomware infections took place this week and have impacted the school districts of three North Louisiana parishes -- Sabine, Morehouse, and Ouachita. IT networks are down at all three school districts, and files have been encrypted and are inaccessible, local media outlets are reporting. By signing the Emergency Declaration, the Louisiana governor is making available state resources to impacted schools. This includes assistance from cybersecurity experts from the Louisiana National Guard, Louisiana State Police, the Office of Technology Services, the Governor's Office of Homeland Security and Emergency Preparedness (GOHSEP), and others. State officials hope that additional IT expertise will speed up the recovery process so schools can resume their activity and preparations for the upcoming school year. Earlier today, some residents of Johannesburg have been left without electricity after a ransomware infection.

The Stopping Bad Robocalls Act passed the U.S. House of Representatives by a nearly unanimous vote, with only two Republicans and one independent voting against the bill. Gizmodo reports: The bill, sponsored by Rep. Frank Pallone Jr., chairman of the House Energy and Commerce Committee, prescribes strict regulations around the use of automatic telephone dialing systems or other artificial or prerecorded messages. The bill specifically requires any entity making robocalls to first obtain the consent of those being called. The bill also requires the creation of reliable mechanisms whereby consumers can withdraw their consent. Emergency services and certain non-commercial entities would be exempt from the new regulations, which would be enforced by the Federal Communications Commission. If passed, the law would also prohibit phone companies from passing on the cost of robocall enforcement to consumers in the form of line-item charges. The bill now heads to the Senate where it's expected to pass without hardly any resistance.

An anonymous reader quotes a report from The Register: Some models of Airbus A350 airliners still need to be hard rebooted after exactly 149 hours, despite warnings from the EU Aviation Safety Agency (EASA) first issued two years ago. In a mandatory airworthiness directive (AD) reissued earlier this week, EASA urged operators to turn their A350s off and on again to prevent "partial or total loss of some avionics systems or functions." The revised AD, effective from tomorrow (26 July), exempts only those new A350-941s which have had modified software pre-loaded on the production line. For all other A350-941s, operators need to completely power the airliner down before it reaches 149 hours of continuous power-on time.

Concerningly, the original 2017 AD was brought about by "in-service events where a loss of communication occurred between some avionics systems and avionics network" (sic). The impact of the failures ranged from "redundancy loss" to "complete loss on a specific function hosted on common remote data concentrator and core processing input/output modules." In layman's English, this means that prior to 2017, at least some A350s flying passengers were suffering unexplained failures of potentially flight-critical digital systems.
