An anonymous reader quotes a report from Polygon: In the wake of storefronts like Steam and itch.io curbing the sale of adult games, irate fans have started an organized campaign against the payment processors that they believe are responsible for the crackdown. While the movement is still in its early stages, people are mobilizing with an eye toward overwhelming communication lines at companies like Visa and Mastercard in a way that will make the concern impossible to ignore. On social media sites like Reddit and Bluesky, people are urging one another to get into contact with Visa and Mastercard through emails and phone calls. Visa and Mastercard have become the targets of interest because the affected storefronts both say that their decisions around adult games were motivated by the danger of losing the ability to use major payment processors while selling games. These payment processors have their own rules regarding usage, but they are vaguely defined. But losing infrastructure like this could impact audiences well beyond those who care about sex games, spokespeople for Valve and itch.io said.

In a now-deleted post on the Steam subreddit with over 17,000 upvotes, commenters say that customer service representatives for both payment processors seem to already be aware of the problem. Sometimes, the representatives will say that they've gotten multiple calls on the subject of adult game censorship, but that they can't really do anything about it. The folks applying pressure know that someone at a call center has limited power in a scenario like this one; typically, agents are equipped to handle standard customer issues like payment fraud or credit card loss. But the point isn't to enact change through a specific phone call: It's to cause enough disruption that the ruckus theoretically starts costing payment processors money.

"Emails can be ignored, but a very very long queue making it near impossible for other clients to get in will help a lot as well," reads the top comment on the Reddit thread. In that same thread, people say that they're hanging onto the call even if the operator says that they'll experience multi-hour wait times presumably caused by similar calls gunking up the lines. Beyond the stubbornness factor, the tactic is motivated by the knowledge that most customer service systems will put people who opt for call-backs in a lower priority queue, as anyone who opts in likely doesn't have an emergency going on. "Do both," one commenter suggests. "Get the call back, to gum up the call back queue. Then call in again and wait to gum up the live queue." People are also using email to voice their concerns directly to the executives at both Visa and Mastercard, payment processors that activist group Collective Shout called out by name in their open letter requesting that adult games get pulled. Emails are also getting sent to customer service.

Christie Wilcox reports via Science.org: Both longhorn crazy ants (Paratrechina longicornis) and humans can figure out how to work together to move an unwieldy object through a series of obstacles. So scientists pitted the two against each other. They had individuals and groups of different sizes of both species maneuver a T-shaped object through holes in walls (as seen in the video above), both of which were scaled to the body size of the participants. This kind of puzzle is hard for ants because their pheromone-based communication doesn't account for the kind of geometry needed to get the object through the doors. To make the experiments even more comparable, the team also took away the humans' communication in some of the trials by making them wear sunglasses and masks and forbidding talking and gestures. So the people, like the ants, had to work together without language, relying on the forces generated by their fellow participants to figure out how to move the T-shaped piece.

The groups of ants were much better at solving the puzzle than individual ants, exhibiting what the researchers described as "emergent" collective memory -- an intelligence greater than the sum of its parts. The groups of humans, on the other hand, often didn't do better when working together, especially if they weren't allowed to talk. In fact, multiple people sometimes performed worse than individuals -- and worse than the ants. The researchers posit that, in the absence of the ability to discuss and debate, individuals attempt to reach a consensus quickly rather than fully assessing the problem. This "groupthink," they suggest, leads people toward fruitless "greedy" efforts where they directly pull the T toward the gaps in the wall, rather than the less obvious, correct solution of pulling the object into the space between first. Whereas the ants "excel in cooperation," they write, humans need to be able to talk through their reasoning to avoid simply going with what they think the crowd wants. The study has been published in the journal Proceedings of the National Academy of Sciences.

Valerie Warner is 71 years old — and owes $268,000 in student loans.

Roughly 40 years ago she went to law school, but was only able to find work as a legal aid and later work in the public school system, which the Washington Post calls "a rewarding job but one that didn't pay enough to wipe out her loans." Later she earned a masters of education degree: All told, Warner borrowed a total of about $60,000 for her two advanced degrees. The amount seemed reasonable given the career trajectory that both credentials promised, but that path never materialized. Working a series of low-wage jobs, she went in and out of forbearance before ultimately defaulting. The balance ballooned to the current $268,000 total over the years due to collection fees and interest capitalization.
And she's not the only one in debt. "On a dreary December afternoon, a group of senior citizens stood in the rain outside the Education Department pleading for relief from a debt that many fear will burden them for the rest of their lives..." Some sat in rocking chairs, cross-stitching their debt number in a pattern. Others held signs that read, "Time is running out, sunset our debt." Or wore T-shirts saying, "Debt relief before we die...."

[A]ctivists are urging the U.S. Education Department to discharge the student debt of older borrowers who they say are in no position to repay. They say the department could use a little-known federal statute that considers a person's ability to pay within a reasonable time and the inability of the government to collect the debt in full. There are 2.8 million federal student loan borrowers aged 62 and older with a total of $121.5 billion in debt, more than 726,300 of them over the age of 71, according to the Education Department. Older borrowers are one of the fastest-growing segments of the government's student loan portfolio, and their Social Security benefits are subject to garnishment...

The Education Department would only acknowledge receiving a memo from the Debt Collective, the group organizing the campaign, outlining the agency's authority to cancel the debt of older borrowers. The activist organization said it has been meeting with members of Congress, White House committees and Education Department officials about the matter since September. "Many of these folks have been borrowers for 20 or 30 years, with punishingly high interest rates. Their balances and the way they have dragged on for decades is just an indictment of the broken system and the failure of past relief efforts," said Eleni Schirmer, an organizer with the Debt Collective... According to the think tank New America, the number of Americans approaching retirement age with student loan debt has skyrocketed over 500 percent in the last two decades. Some have loans they took out to finance their college educations, while others took out federal Parent Plus loans or co-signed private loans for their children.
The article points out that the U.S. government will garnish up to 15 percent of the Social Security income to recoup student loan debt, even if it means leaving recipients below the poverty line.

But it also includes this quote from Adam Minsky, an attorney who specializes in student debt, about the prospects for federal action that survives challenges in the U.S. court system. "[A]s a practical matter, I don't think that judges and courts that have been hostile to mass debt relief would treat this differently from other programs that have been blocked or struck down."

Bruce Perens, original co-founder of the Open Source Initiative, has responded to questions from Slashdot readers about a new alternative he's developing that hopefully helps "Post Open" developers get paid.

But first, "One of the things that's clear from the Slashdot patter is that people are not aware of what I've been doing, in general," Perens says. "So, let's start by filling that in..."

Read on for the rest of his wide-ranging answers....

An anonymous reader quotes a report from TechCrunch: The CEO of AI search company Perplexity, Aravind Srinivas, has offered to cross picket lines and provide services to mitigate the effect of a strike by New York Times tech workers. The NYT Tech Guild announced its strike Monday, after setting November 4 as its deadline months earlier. The workers represented provide software support and data analysis for the Times, on the business side of the outlet. They have been asking for an annual 2.5% wage increase and to cement a current two days per week in-office expectation, among other things. [...] Picketers demonstrated in front of the NYT building in New York as negotiations continued. Meanwhile, on X, formerly known as Twitter, Perplexity's CEO offered to step in for the striking workers.

Replying to Semafor media editor Max Tani quoting the publisher, Srinivas wrote: "Hey AG Sulzberger @nytimes sorry to see this. Perplexity is on standby to help ensure your essential coverage is available to all through the election. DM me anytime here." Many on X immediately castigated Srinivas for acting as a scab -- a derogatory term for people willing to perform the jobs of striking workers. It is widely considered a disreputable behavior in matters of labor and equity. By undercutting collective action, scabs limit the ability of workers to bargain with those in positions of power. Srinivas may simply be trying to make sure people have the information they need on election day. The company has lately unveiled its own elections info hub and map. But to offer its services explicitly as a replacement for striking workers was bound to be an unpopular move.

Though TechCrunch asked Perplexity for comment, Srinivas responded to TechCrunch's post on X saying that "the offer was *not* to 'replace' journalists or engineers with AI but to provide technical infra support on a high-traffic day." The striking workers in question, however, are the ones who provide that service to the NYT. It's not really clear what services other than AI tools Perplexity could offer, or why they would not amount to replacing the workers in question.

SC World reports: Several major end-to-end encrypted cloud storage services contain cryptographic flaws that could lead to loss of confidentiality, file tampering, file injection and more, researchers from ETH Zurich said in a paper published this month.

The five cloud services studied offer end-to-end encryption (E2EE), intended to ensure files can not be read or edited by anyone other than the uploader, meaning not even the cloud storage provider can access the files. However, ETH Zurich researchers Jonas Hofmann and Kien Tuong Truong, who presented their findings at the ACM Conference on Computer and Communications Security (CCS) last week, found serious flaws in four out of the five services that could effectively bypass the security benefits provided by E2EE by enabling an attacker who managed to compromise a cloud server to access, tamper with or inject files.

The E2EE cloud storage services studied were Sync, pCloud, Seafile, Icedrive and Tresorit, which have a collective total of about 22 million users. Tresorit had the fewest vulnerabilities, which could enable some metadata tampering and use of non-authentic keys when sharing files. The other four services were found to have more severe flaws posing a greater risk to file confidentiality and integrity.
BleepingComputer reports that Sync is "fast-tracking fixes," while Seafile "promised to patch the protocol downgrade problem on a future upgrade." And SC World does note that all 10 of the tested exploits "would require the attacker to have already gained control of a server with the ability to read, modify and inject data.

"The authors wrote that they consider this to be a realistic threat model for E2EE services, as these services are meant to protect files even if such a compromise was to occur."

Midjourney version 6, the latest and greatest iteration of the popular image generation AI model from the research collective of the same name founded by David Holz, dropped last night as an alpha release. From a report: Among those new features are drastically improved and more realistic, highly detailed images, and the ability to have the model generate legible text within images, something that had eluded Midjourney since its release in 2022 even as other rival AI image generators such as OpenAI's DALL-E 3 and Ideogram had launched this type of feature. "This model can generate much more realistic imagery than anything we've released before," wrote Holz in a message posted in the Midjourney Discord server, which has over 17 million members. Holz said V6 was actually the "third model trained from scratch on our AI superclusters" and took nine months to develop.

It happened a quarter of a century ago. The New York Times wrote that "An internal memorandum reflecting the views of some of Microsoft's top executives and software development managers reveals deep concern about the threat of free software and proposes a number of strategies for competing against free programs that have recently been gaining in popularity." The memo warns that the quality of free software can meet or exceed that of commercial programs and describes it as a potentially serious threat to Microsoft. The document was sent anonymously last week to Eric Raymond, a key figure in a loosely knit group of software developers who collaboratively create and distribute free programs ranging from operating systems to Web browsers. Microsoft executives acknowledged that the document was authentic...

In addition to acknowledging that free programs can compete with commercial software in terms of quality, the memorandum calls the free software movement a "long-term credible" threat and warns that employing a traditional Microsoft marketing strategy known as "FUD," an acronym for "fear, uncertainty and doubt," will not succeed against the developers of free software. The memorandum also voices concern that Linux is rapidly becoming the dominant version of Unix for computers powered by Intel microprocessors.

The competitive issues, the note warns, go beyond the fact that the software is free. It is also part of the open-source software, or O.S.S., movement, which encourages widespread, rapid development efforts by making the source code — that is, the original lines of code written by programmers — readily available to anyone. This enables programmers the world over to continually write or suggest improvements or to warn of bugs that need to be fixed. The memorandum notes that open software presents a threat because of its ability to mobilize thousands of programmers. "The ability of the O.S.S. process to collect and harness the collective I.Q. of thousands of individuals across the Internet is simply amazing," the memo states. "More importantly, O.S.S. evangelization scales with the size of the Internet much faster than our own evangelization efforts appear to scale."
Back in 1998, Slashdot's CmdrTaco covered the whole brouhaha — including this CNN article: A second internal Microsoft memo on the threat Linux poses to Windows NT calls the operating system "a best-of-breed Unix" and wonders aloud if the open-source operating system's momentum could be slowed in the courts.

As with the first "Halloween Document," the memo — written by product manager Vinod Valloppillil and another Microsoft employee, Josh Cohen — was obtained by Linux developer Eric Raymond and posted on the Internet. In it, Cohen and Valloppillil, who also authored the first "Halloween Document," appear to suggest that Microsoft could slow the open-source development of Linux with legal battles. "The effect of patents and copyright in combating Linux remains to be investigated," the duo wrote.
Microsoft's slogain in 1998 was "Where do you want to go today?" So Eric Raymond published the documents on his web site under the headline "Where will Microsoft try to drag you today? Do you really want to go there?"

25 years later, and it's all still up there and preserved for posterity on Raymond's web page — a collection of leaked Microsoft documents and related materials known collectively as "the Halloween documents." And Raymond made a point of thanking the writers of the documents, "for authoring such remarkable and effective testimonials to the excellence of Linux and open-source software in general."

Thanks to long-time Slashdot reader mtaht for remembering the documents' 25th anniversary...

The NFC Forum has revealed a roadmap for NFC technology that extends from now to 2028. The roadmap outlines five key initiatives for the direction of the technology over the next two to five years, including increasing the range of NFC connections, increasing wireless charging over NFC, enabling multiple-purpose taps, giving NFC-enabled smartphones Point-of-Sale functionality, and the ability to share how products should be recycled. Android Authority reports: Currently, NFC connections only work at a distance of 5mm. However, the NFC Forum wants to extend this distance by four to six times. Not only would this allow contactless payments to become truly contactless, but it would also make transactions faster and easier. Even a modest change is said to be enough to reduce the precision needed to align the antenna. Improving the range was far from the only matter the collective was looking into. The group shared that it wanted to increase wireless charging over NFC from 1W to 3W. Doing so would allow for wireless power and charging in smaller devices. It could even allow the creation of new applications previously left unexplored.

Another initiative is to enable multiple-purpose taps. This would reportedly make supporting several actions with a single tap possible. Additionally, the group mentioned giving NFC-enabled smartphones Point-of-Sale functionality and the ability to share how products should be recycled.

A New York Times opinion piece argues people in the AI industry "are desperate to be regulated, even if it slows them down. In fact, especially if it slows them down." But how? What they tell me is obvious to anyone watching. Competition is forcing them to go too fast and cut too many corners. This technology is too important to be left to a race between Microsoft, Google, Meta and a few other firms. But no one company can slow down to a safe pace without risking irrelevancy. That's where the government comes in — or so they hope... [A]fter talking to a lot of people working on these problems and reading through a lot of policy papers imagining solutions, there are a few categories I'd prioritize.

The first is the question — and it is a question — of interpretability. As I said above, it's not clear that interpretability is achievable. But without it, we will be turning more and more of our society over to algorithms we do not understand... The second is security. For all the talk of an A.I. race with China, the easiest way for China — or any country for that matter, or even any hacker collective — to catch up on A.I. is to simply steal the work being done here. Any firm building A.I. systems above a certain scale should be operating with hardened cybersecurity. It's ridiculous to block the export of advanced semiconductors to China but to simply hope that every 26-year-old engineer at OpenAI is following appropriate security measures.

The third is evaluations and audits. This is how models will be evaluated for everything from bias to the ability to scam people to the tendency to replicate themselves across the internet. Right now, the testing done to make sure large models are safe is voluntary, opaque and inconsistent. No best practices have been accepted across the industry, and not nearly enough work has been done to build testing regimes in which the public can have confidence. That needs to change — and fast.
The piece also recommends that AI-design companies "bear at least some liability for what their models." But what legislation should we see — and what legislation will we see? "One thing regulators shouldn't fear is imperfect rules that slow a young industry," the piece argues.

"For once, much of that industry is desperate for someone to help slow it down."

An anonymous reader quotes a report from Phys.Org: Like electronics or photonics, magnonics is an engineering subfield that aims to advance information technologies when it comes to speed, device architecture, and energy consumption. A magnon corresponds to the specific amount of energy required to change the magnetization of a material via a collective excitation called a spin wave. Because they interact with magnetic fields, magnons can be used to encode and transport data without electron flows, which involve energy loss through heating (known as Joule heating) of the conductor used. As Dirk Grundler, head of the Lab of Nanoscale Magnetic Materials and Magnonics (LMGN) in the School of Engineering explains, energy losses are an increasingly serious barrier to electronics as data speeds and storage demands soar. "With the advent of AI, the use of computing technology has increased so much that energy consumption threatens its development," Grundler says. "A major issue is traditional computing architecture, which separates processors and memory. The signal conversions involved in moving data between different components slow down computation and waste energy."

This inefficiency, known as the memory wall or Von Neumann bottleneck, has had researchers searching for new computing architectures that can better support the demands of big data. And now, Grundler believes his lab might have stumbled on such a "holy grail". While doing other experiments on a commercial wafer of the ferrimagnetic insulator yttrium iron garnet (YIG) with nanomagnetic strips on its surface, LMGN Ph.D. student Korbinian Baumgaertl was inspired to develop precisely engineered YIG-nanomagnet devices. With the Center of MicroNanoTechnology's support, Baumgaertl was able to excite spin waves in the YIG at specific gigahertz frequencies using radiofrequency signals, and -- crucially -- to reverse the magnetization of the surface nanomagnets. "The two possible orientations of these nanomagnets represent magnetic states 0 and 1, which allows digital information to be encoded and stored," Grundler explains.

The scientists made their discovery using a conventional vector network analyzer, which sent a spin wave through the YIG-nanomagnet device. Nanomagnet reversal happened only when the spin wave hit a certain amplitude, and could then be used to write and read data. "We can now show that the same waves we use for data processing can be used to switch the magnetic nanostructures so that we also have nonvolatile magnetic storage within the very same system," Grundler explains, adding that "nonvolatile" refers to the stable storage of data over long time periods without additional energy consumption. It's this ability to process and store data in the same place that gives the technique its potential to change the current computing architecture paradigm by putting an end to the energy-inefficient separation of processors and memory storage, and achieving what is known as in-memory computation. The research has been published in the journal Nature Communications.

Anyone remember the high-end commercial UNIX workstations from a few decades ago — like from companies like IBM, DEC, SGI, and Sun Microsystems?

Today OSnews looked back — but also explored what happens when you try to buy one today> : As x86 became ever more powerful and versatile, and with the rise of Linux as a capable UNIX replacement and the adoption of the NT-based versions of Windows, the days of the UNIX workstations were numbered. A few years into the new millennium, virtually all traditional UNIX vendors had ended production of their workstations and in some cases even their associated architectures, with a lacklustre collective effort to move over to Intel's Itanium — which didn't exactly go anywhere and is now nothing more than a sour footnote in computing history.

Approaching roughly 2010, all the UNIX workstations had disappeared.... and by now, they're all pretty much dead (save for Solaris). Users and industries moved on to x86 on the hardware side, and Linux, Windows, and in some cases, Mac OS X on the software side.... Over the past few years, I have come to learn that If you want to get into buying, using, and learning from UNIX workstations today, you'll run into various problems which can roughly be filed into three main categories: hardware availability, operating system availability, and third party software availability.
Their article details their own attempts to buy one over the years, ultimately concluding the experience "left me bitter and frustrated that so much knowledge — in the form of documentation, software, tutorials, drivers, and so on — is disappearing before our very eyes." Shortsightedness and disinterest in their own heritage by corporations, big and small, is destroying entire swaths of software, and as more years pass by, it will get ever harder to get any of these things back up and running.... As for all the third-party software — well, I'm afraid it's too late for that already. Chasing down the rightsholders is already an incredibly difficult task, and even if you do find them, they are probably not interested in helping you, and even if by some miracle they are, they most likely no longer even have the ability to generate the required licenses or release versions with the licensing ripped out. Stuff like Pro/ENGINEER and SoftWindows for UNIX are most likely gone forever....

Software is dying off at an alarming rate, and I fear there's no turning the tide of this mass extinction.
The article also wonders why companies like HPE don't just "dump some ISO files" onto an FTP server, along with patch depots and documentation. "This stuff has no commercial value, they're not losing any sales, and it will barely affect their bottom line.

Snapchat's parent company is asking workers to return to the office 80% of the time, or the equivalent of four days a week, beginning early next year, in the latest sign of tech employees receiving less flexibility nearly three years after the pandemic took hold and amid a wave of industry cost cutting. CNN reports: "After working remotely for so long we're excited to get everyone back together next year with our new 80/20 hybrid model," a spokesperson for Snap (SNAP) confirmed to CNN in a statement Tuesday. "We believe that being together in person, while retaining flexibility for our team members, will enhance our ability to deliver on our strategic priorities of growing our community, driving revenue growth, and leading in [augmented reality]." The new policy will take effect at the end of February.

News of Snap's stricter in-office policy was first reported by Bloomberg, which cited an internal memo from CEO Evan Spiegel telling employees they may have to "sacrifice" some amount of "individual convenience" but it will benefit "our collective success."

An anonymous reader quotes a report from the Guardian: A group of New Zealand Uber drivers have won a landmark case against the global ridesharing company, forcing it to treat them as employees, not contractors, and entitling them to a suite of worker rights and protections. New Zealand's employment court ruled on Tuesday that the drivers were employees, not independent contractors. While the ruling applies specifically to the case of four drivers, the court noted that it may have wider implications for drivers across the country. The court "does not have jurisdiction to make broader declarations of employment status" so all Uber drivers "do not, as a result of this judgment, instantly become employees," chief judge Christina Inglis wrote. She continued, however: "It may well have broader impact, particularly where, as here, there is apparent uniformity in the way in which the companies operate, and the framework under which drivers are engaged."

Employment status is the bedrock on which most of New Zealand's minimum employment rights rest. It is "the gate through which a worker must pass" before they can access legal minimum entitlements including the minimum wage, six minimum hours of work, rest and meal breaks, holidays, parental leave, domestic violence leave, bereavement leave, ability to pursue a personal grievance, and access to union membership and collective bargaining. A spokesperson for Uber said the company was "disappointed" and would be appealing against the decision. They said it was "too soon to speculate" on whether New Zealand's drivers having employee status would affect the company's operations in the country more broadly.

An anonymous reader quotes a report from The Register: A dozen US midwestern research colleges and universities have signed up to a project intended to bolster the semiconductor and microelectronics industries with combined research and education to ensure work for their students in high-tech industries. The "Midwest Regional Network to Address National Needs in Semiconductor and Microelectronics" consists of a dozen institutions, made up of eight from Ohio, two from Michigan, and two from Indiana. Their stated aim is to support the onshoring efforts of the US semiconductor industry by addressing the need for research and a skilled workforce.

According to Wright State University, the network was formed in response to Intel's announcement that it planned to build two chip factories near Columbus, Ohio, and followed a two-day workshop in April hosted by the state. [...] However, the university network was also formed to help address the broader national effort to regain American leadership in semiconductors and microelectronics, or at least bring some of it back onshore and make the US less reliant on supplies of chips manufactured abroad.

The president of each institution has signed a memorandum of understanding to form the network, and the expectation is that the group will expand to include more than these dozen initial members. The intention is that the institutions taking part will be able to make use of each other's existing research, learning programs, capabilities, and expertise in order to boost their collective ability to support the semiconductor and microelectronics industry ecosystems. Challenges for the network include developing mechanisms to connect existing research, and training assets across the region, and developing a common information sharing platform to make it easier to identify opportunities for joint programming and research across the network. The institutions involved in the network include: Wright State University, Columbus State Community College, Lorain County Community College, Michigan State University, Ohio State University, Purdue University, Sinclair Community College, University of Cincinnati, University of Dayton, University of Michigan, and the University of Notre Dame, Indiana.

An anonymous reader quotes a report from International Business Times: US scientists have developed a new form of drug that promotes the regeneration of cells and reversed paralysis in mice with spinal injuries, allowing them to walk again within four weeks of treatment. The research was published in the journal Science on Thursday, and the team of Northwestern University scientists behind it hope to approach the Food and Drug Administration as early as next year to propose human trials. [Northwestern's Samuel Stupp, who led the study, and his team] used nanofibers to mimic the architecture of the "extracellular matrix" -- a naturally occurring network of molecules surrounding tissue that is responsible for supporting cells. Each fiber is about 10,000 times narrower than a human hair, and they are made up of hundreds of thousands of bioactive molecules called peptides that transmit signals to promote nerve regeneration. The therapy was injected as a gel into tissue surrounding the spinal cords of lab mice 24 hours after an incision was made in their spines.

The team decided to wait a day because humans who receive devastating spinal injuries from car accidents, gunshots and so on also experience delays in getting treatment. Four weeks later, mice who received the treatment regained their ability to walk almost as well as before the injury. Those left untreated did not. The mice were then put down to examine the impacts of the therapy on the cellular level, and the team found dramatic improvements to the spinal cords. The severed extensions of neurons called axons regenerated, and scar tissue that can act as a physical barrier to regeneration was significantly diminished. What's more, an insulating layer of axons called myelin that is important in transmitting electric signals had reformed, blood vessels that deliver nutrients to injured cells had formed, and more motor neurons survived.

A key discovery by the team was that creating a certain mutation in the molecules intensified their collective motion and heightened their efficacy. This is because receptors in neurons are naturally in constant motion, Stupp explained, and increasing the motion of the therapeutic molecules within the nanofibers helps connect them more effectively with their moving targets. The researchers in fact tested two versions of the treatment -- one with the mutation and one without -- and found that mice that received the modified version regained more function. The gel developed by the scientists is the first of its kind, but could usher in a new generation of medicines known as "supramolecular drugs," because the therapy is an assembly of many molecules rather than a single molecule, said Stupp. According to the team, it is safe because the materials biodegrade within a matter of weeks and become nutrients for cells. Stupp said he hopes to rapidly move direct to human studies next without the need for further animal testing, such as on primates.

Aalto University reports via Phys.Org: When two substances are brought together, they will eventually settle into a steady state called thermodynamic equilibrium; examples include oil floating on top of water and milk mixing uniformly into coffee. Researchers at Aalto University in Finland wanted to disrupt this sort of state to see what happens -- and whether they can control the outcome. In their work, the team used combinations of oils with different dielectric constants and conductivities. They then subjected the liquids to an electric field. "When we turn on an electric field over the mixture, electrical charge accumulates at the interface between the oils. This charge density shears the interface out of thermodynamic equilibrium and into interesting formations," explains Dr. Nikos Kyriakopoulos, one of the authors of the paper. As well as being disrupted by the electric field, the liquids were confined into a thin, nearly two-dimensional sheet. This combination led to the oils reshaping into various completely unexpected droplets and patterns.

The droplets in the experiment could be made into squares and hexagons with straight sides, which is almost impossible in nature, where small bubbles and droplets tend to form spheres. The two liquids could be also made to form into interconnected lattices: grid patterns that occur regularly in solid materials but are unheard of in liquid mixtures. The liquids can even be coaxed into forming a torus, a donut shape, which was stable and held its shape while the field was applied -- unlike in nature, as liquids have a strong tendency to collapse in and fill the hole at the center. The liquids can also form filaments that roll and rotate around an axis. One of the exciting results of this work is the ability to create temporary structures with a controlled and well-defined size which can be turned on and off with voltage, an area that the researchers are interested in exploring further for creating voltage-controlled optical devices. Another potential outcome is the ability to create interacting populations of rolling microfilaments and microdroplets that, at some elementary level, mimic the dynamics and collective behavior of microorganisms like bacteria and microalgae that propel themselves using completely different mechanisms. The research has been published in the journal Science Advances.

From today's edition of Mike Melanson's "This Week in Programming" column: This week, Docker announced some changes to Docker Hub Autobuilds — the primary one of interest being that autobuilds would no longer be available to free tier users — and much of the internet let out a collective groan to the tune of "this is why we can't have nice things...!"

"As many of you are aware, it has been a difficult period for companies offering free cloud compute," wrote Shaun Mulligan, principal product manager at Docker in the company's blog post, citing an article that explores how crypto-mining gangs are running amok on free cloud computing platforms. Mulligan goes on to explain that Docker has "seen a massive growth in the number of bad actors," noting that it not only costs them money, but also degrades performance for their paying customers. And so, after seven years of free access to their autobuild feature, wherein even all of you non-paying Docker users could set up continuous integration for your containerized projects, gratis, the end is nigh. Like, really, really nigh, as in next week — June 18.

While Docker offered that they already tried to correct the issue by removing around 10,000 accounts, they say that the miners returned the next week in droves, and so they "made the hard choice to remove Autobuilds...." For its part, Docker has tried to again stave off the criticism, offering users a discount on subscriptions, and offering members of its open source program the ability to continue to use autobuilds for free...
Docker says they've also changed Autobuild "to take advantage of BuildKit by default for improved build performance," increased the number of parallel builds for subscribers, and increased the build instance types, "so you get a beefier machine to build on!" While the changes were apparently inspired by their struggles with cryptocurrency miners, "All of these improvements should see a faster and more stable build experience with lower queue times..."

An anonymous reader shares a report: Academic and scientific research needs to be accessible to all. The world's most pressing problems like clean water or food security deserve to have as many people as possible solving their complexities. Yet our current academic research system has no interest in harnessing our collective intelligence. Scientific progress is currently thwarted by one thing: paywalls. Paywalls, which restrict access to content without a paid subscription, represent a common practice used by academic publishers to block access to scientific research for those who have not paid. This keeps $25.5bn flowing from higher education and science into for-profit publisher bank accounts.

My recent documentary, Paywall: The Business of Scholarship, uncovered that the largest academic publisher, Elsevier, regularly has a profit margin between 35-40%, which is greater than Google's. With financial capacity comes power, lobbyists, and the ability to manipulate markets for strategic advantages â" things that underfunded universities and libraries in poorer countries do not have. Furthermore, university librarians are regularly required to sign non-disclosure agreements on their contract-pricing specifics with the largest for-profit publishers. Each contract is tailored specifically to that university based upon a variety of factors: history, endowment, current enrolment. This thwarts any collective discussion around price structures, and gives publishers all the power.

Tim Berners-Lee, writing for The New York Times: All technologies come with risks. We drive cars despite the possibility of serious accidents. We take prescription drugs despite the danger of abuse and addiction. We build safeguards into new innovations so we can manage the risks while benefiting from the opportunities. The web is a global platform -- its challenges stretch across borders and cultures. Just as the web was built by millions of people collaborating around the world, its future relies on our collective ability to make it a better tool for everyone.

As we forge the web of tomorrow, we need a set of guiding principles that can define the kind of web we want. Identifying these will not be easy -- any agreement that covers a diverse group of countries, cultures and interests will never be. But I believe it's possible to develop a set of basic ideals that we can all agree on, and that will make the web work better for everyone, including the 50 percent of the world's population that has yet to come online.

Governments, companies and individuals all have unique roles to play. The World Wide Web Foundation, an organization I founded in 2009 to protect the web as a public good, has drawn up a set of core principles outlining the responsibilities that each party has to protect a web that serves all of humanity. We're asking everyone to sign on to these principles and join us as we create a formal Contract for the Web in 2019. The principles specify that governments are responsible for connecting their citizens to an open web that respects their rights.
