Synthetic Magnetic Fields Steer Light On a Chip For Faster Communications

2025-09-13 15:00:00

Researchers in China have created synthetic magnetic fields within silicon photonic crystals, allowing them to steer and control light on a chip with unprecedented precision. "Beyond immediate applications, the work opens new avenues for studying quantum-inspired phenomena with light," reports Phys.org. "The ability to impose artificial gauge fields in photonic systems could enable devices for optical computing, quantum information, and advanced communication technologies." Slashdot reader alternative_right shares an excerpt from the report: The team achieved this by systematically altering the symmetry of tiny repeating units in silicon photonic crystals. Adjusting the degree of local asymmetry at each point allowed them to 'design' pseudomagnetic fields with tailored spatial patterns, without breaking fundamental time-reversal symmetry. Both theoretical analysis and experiments confirmed that these engineered fields can guide and manipulate light in versatile ways. To demonstrate practical applications, the researchers built two devices commonly used in integrated optics. One was a compact S-shaped waveguide bend that transmitted light with less than 1.83 decibels of signal loss. The other was a power splitter that divided light into two equal paths with low excess loss and minimal imbalance. In a final test, the devices successfully transmitted a high-speed data stream at 140 gigabits per second using a standard telecommunications modulation format, showing that the technique is compatible with existing optical communication systems. The research has been published in Advanced Photonics.

Proton Mail Suspended Journalist Accounts At Request of Cybersecurity Agency

2025-09-13 11:30:00

An anonymous reader quotes a report from The Intercept: The company behind the Proton Mail email service, Proton, describes itself as a "neutral and safe haven for your personal data, committed to defending your freedom." But last month, Proton disabled email accounts belonging to journalists reporting on security breaches of various South Korean government computer systems following a complaint by an unspecified cybersecurity agency. After a public outcry, and multiple weeks, the journalists' accounts were eventually reinstated -- but the reporters and editors involved still want answers on how and why Proton decided to shut down the accounts in the first place. Martin Shelton, deputy director of digital security at the Freedom of the Press Foundation, highlighted that numerous newsrooms use Proton's services as alternatives to something like Gmail "specifically to avoid situations like this," pointing out that "While it's good to see that Proton is reconsidering account suspensions, journalists are among the users who need these and similar tools most." Newsrooms like The Intercept, the Boston Globe, and the Tampa Bay Times all rely on Proton Mail for emailed tip submissions. Shelton noted that perhaps Proton should "prioritize responding to journalists about account suspensions privately, rather than when they go viral." On Reddit, Proton's official account stated that "Proton did not knowingly block journalists' email accounts" and that the "situation has unfortunately been blown out of proportion." The two journalists whose accounts were disabled were working on an article published in the August issue of the long-running hacker zine Phrack. The story described how a sophisticated hacking operation -- what's known in cybersecurity parlance as an APT, or advanced persistent threat -- had wormed its way into a number of South Korean computer networks, including those of the Ministry of Foreign Affairs and the military Defense Counterintelligence Command, or DCC. The journalists, who published their story under the names Saber and cyb0rg, describe the hack as being consistent with the work of Kimsuky, a notorious North Korean state-backed APT sanctioned by the U.S. Treasury Department in 2023. As they pieced the story together, emails viewed by The Intercept show that the authors followed cybersecurity best practices and conducted what's known as responsible disclosure: notifying affected parties that a vulnerability has been discovered in their systems prior to publicizing the incident. Phrack said the account suspensions created a "real impact to the author. The author was unable to answer media requests about the article." Phrack noted that the co-authors were already working with affected South Korean organizations on responsible disclosure and system fixes. "All this was denied and ruined by Proton," Phrack stated. Phrack editors said that the incident leaves them "concerned what this means to other whistleblowers or journalists. The community needs assurance that Proton does not disable accounts unless Proton has a court order or the crime (or ToS violation) is apparent."

US EV Sales Smash Records In August

2025-09-13 09:50:00

US EV sales hit a record 146,332 in August, grabbing nearly 10% of all new car sales, according to Kelley Blue Book. That's the highest yet and up from 9.1% in July. Electrek reports: With the federal EV tax credit set to expire on September 30, analysts say Q3 2025 is shaping up to be the strongest quarter for EV sales in US history. The current record holder is Q4 2024, when 365,824 EVs were sold. Prices ticked higher, too. The average transaction price (ATP) for an EV in August was $57,245, 3.1% more than July's revised lower ATP of $55,562. Year-over-year, though, EV prices were basically flat, down just 0.1%. The wave of EV sales also helped push up the overall market's ATP. Incentives, while not as high as July's record, remained hefty. EV buyers received discounts averaging over $9,000 in August, equal to 16% of ATP. That's more than double the incentive rate in the overall auto market and up from 13.6% a year ago. A separate report from Rho Motion found that global EV sales surged 25% in 2025, led by strong growth in Europe and China. "That amounts to 12.5 million EVs, although the data combines both battery EVs and plug-in hybrid EVs for the total," reports Ars Technica. As for North America? "EV sales are still growing but barely -- up just 6 percent between January and August 2025 compared to the same time period in 2024."

Newfoundland's 10-Year Education Report Calling For Ethical AI Use Contains Over 15 Fake Sources

2025-09-13 09:10:00

Newfoundland and Labrador's 10-year Education Accord report (PDF) intended to guide school reform has been found to contain at least 15 fabricated citations, including references to non-existent films and journals. Academics suggest the fake sources may have been generated by AI. "There are sources in this report that I cannot find in the MUN Library, in the other libraries I subscribe to, in Google searches. Whether that's AI, I don't know, but fabricating sources is a telltale sign of artificial intelligence," said Aaron Tucker, an assistant professor at Memorial whose current research focuses on the history of AI in Canada. "The fabrication of sources at least begs the question: did this come from generative AI?" CBC News reports: In one case, the report references a 2008 movie from the National Film Board called Schoolyard Games. The film doesn't exist, according to a spokesperson for the board. But the exact citation used in the report can be found in a University of Victoria style guide -- a document that clearly lists fake references designed as templates for researchers writing a bibliography. "Many citations in this guide are fictitious," reads the first page of the document. "Errors happen. Made-up citations are a totally different thing where you essentially demolish the trustworthiness of the material," said Josh Lepawsky, the former president of the Memorial University Faculty Association who resigned from the report's advisory board last January, citing a "deeply flawed process" leading to "top-down" recommendations. The 418-page Education Accord NL report took 18 months to complete and was unveiled Aug. 28 by its co-chairs Anne Burke and Karen Goodnough, both professors at Memorial's Faculty of Education. The pair released the report alongside Education Minister Bernard Davis. "We are investigating and checking references, so I cannot respond to this at the moment," wrote Goodnough in an email declining an interview Thursday. In a statement, the Department of Education and Early Childhood Development said it was aware of a "small number of potential errors in citations" in the report. "We understand that these issues are being addressed, and that the online report will be updated in the coming days to rectify any errors."

Employee Who Leaked 'Spider-Man' Blu-ray Sentenced to Nearly 5 Years Prison

2025-09-13 08:30:00

A former Memphis disc manufacturing employee has been sentenced to nearly five years in prison after stealing pre-release Blu-rays from his employer and leaking them online. While he received 21 months for copyright infringement, a concurrent firearm charge extended his total prison term to 57 months. TorrentFreak reports: In February, the U.S. Department of Justice indicted 37-year-old Steven Hale from Tennessee, a former employee of a disc manufacturing and distribution company in Memphis. While working at the unnamed company between 2021 and 2022, Hale allegedly stole numerous "pre-release" DVD and Blu-ray discs from his employer. These stolen discs contained many high-profile movie titles including "Spider-Man: No Way Home." In addition to the copyright infringement charge, Hale was also indicted for a firearm offense. When raiding his premises, law enforcement found a gun in a car that was registered in his name, which, for a felon, is a separate criminal offense. Hale was sentenced at a federal court in Memphis yesterday, where Chief Judge Sheryl H. Lipman handed down a 57-month prison term, exactly in line with the U.S. government's recommendation. Two separate sentences will be served concurrently. Hale received 21 months for the theft and distribution of hundreds of pre-release movie discs. A longer sentence of 57 months was handed down for the firearm charge, which ultimately defines the total prison term. Judge Lipman also granted several requests by the defense. The court recommended that Hale be housed in a facility as close to Memphis as possible so he can be near his family. In addition, the defendant will be allowed to remain on bond and self-surrender to prison at a later date. The 21-month sentence for the copyright infringement charge is substantially lower than the maximum of 60 months. This is in part the result of a guilty plea the defendant signed in May. After accepting responsibility, the prosecution agreed to drop other charges and recommend a sentence at the low end of the guideline range. Hale entered his guilty plea to Count Two of the indictment. The charge relates to his distribution of ten or more copies of copyrighted works, including pre-release movies, for commercial advantage and private financial gain. This includes the pre-release 'Spider-Man: No Way Home' disc, which is likely the source of the public leak.

From Discord To Bitchat, Tech At the Heart of Nepal Protests

2025-09-13 07:50:00

An anonymous reader quotes a report from France24: Fueled in part by anger over flashy lifestyles flaunted by elites, young anti-corruption demonstrators mainly in their 20s rallied on Monday. The loose grouping, largely viewed as members of "Gen Z", flooded the capital Kathmandu to demand an end to a ban on Facebook, YouTube and other popular sites. The rallies ended in chaos and tragedy, with at least 19 protesters killed in a police crackdown on Monday. The apps were restored, but protests widened in anger. On Tuesday, other Nepalis joined the crowds. Parliament was set ablaze, KP Sharma Oli resigned as prime minister, and the army took charge of the streets. Now, many activists are taking to the US group-chat app Discord to talk over their next steps. One server with more than 145,000 members has hosted feverish debate about who could be an interim leader, with many pushing 73-year-old former chief justice Sushila Karki. It is just one example of how social media has driven demands for change. [...] More than half of Nepal's 30 million people are online, according to the World Bank. Days before the protests, many had rushed to VPN services — or virtual private networks — to evade blocks on platforms. Fears of a wider internet shutdown also drove a surge in downloads for Bluetooth messaging app Bitchat, created by tech billionaire Jack Dorsey. "Tech played... an almost decisive role," journalist Pranaya Rana told AFP. "The whole thing started with young people posting on social media about corruption, and the lavish lives that the children of political leaders were leading." Hashtags such as #NepoKids, short for nepotism, compared the designer clothing and luxury holidays shown off in their Instagram posts to the difficulties faced by ordinary Nepalis. One post liked 13,000 times accused politicians' children of "living like millionaires," asking: "Where is the tax money going?" "NepoKids was trending all the time," including in rural areas where Facebook is popular, said rights activist Sanjib Chaudhary. "This fuelled the fire" of anger that "has been growing for a long time," he said. [...] Chaudhary said the government "seriously underestimated the power of social media." Nepal's first female prime minister was sworn in Friday as interim leader after protesters held an informal vote on Discord. "Former chief justice Sushila Karki, 73, was the unlikely choice of the 'Gen Z' protesters behind the movement that started out as a social media demonstration against the lavish lifestyles of 'Nepo Kids' but spilled out onto the streets and into the deadliest social unrest Nepal has seen in years," reports CNN World. "Karki has spent much of her career within the very establishment the youth are protesting against, yet her reputation as a fearless and incorruptible jurist has appealed to many young people in the country of 30 million."
