Is WhatsApp Being Ditched for Signal in Dutch Higher Education? (dub.uu.nl) 42

For weeks Signal has been one of the three most-downloaded apps in the Netherlands, according to a local news site. And now "Higher education institutions in the Netherlands have been looking for an alternative," according to DUB (an independent news site for the Utrecht University community): Employees of the Utrecht University of Applied Sciences (HU) were recently advised to switch to Signal. Avans University of Applied Sciences has also been discussing a switch...The National Student Union is concerned about privacy. The subject was raised at last week's general meeting, as reported by chair Abdelkader Karbache, who said: "Our local unions want to switch to Signal or other open-source software."
Besides being open source, Signal is a non-commercial nonprofit, the article points out — though its proponents suggest there's another big difference. "HU argues that Signal keeps users' data private, unlike WhatsApp." Cybernews.com explains the concern: In an interview with the Dutch newspaper De Telegraaf, Meredith Whittaker [president of the Signal Foundation] discussed the pitfalls of WhatsApp. "WhatsApp collects metadata: who you send messages to, when, and how often. That's incredibly sensitive information," she says.... The only information [Signal] collects is the date an account was registered, the time when an account was last active, and hashed phone numbers... Information like profile name and the people a user communicates with is all encrypted... Metadata might sound harmless, but it couldn't be further from the truth. According to Whittaker, metadata is deadly. "As a former CIA director once said: 'We kill people based on metadata'."
WhatsApp's metadata also includes IP addresses, TechRadar noted last May: Other identifiable data such as your network details, the browser you use, ISP, and other identifiers linked to other Meta products (like Instagram and Facebook) associated with the same device or account are also collected... [Y]our IP can be used to track down your location. As the company explained, even if you keep the location-related features off, IP addresses and other collected information like phone number area codes can be used to estimate your "general location."

WhatsApp is required by law to share this information with authorities during an investigation...

[U]nder scrutiny is how Meta itself uses these precious details for commercial purposes. Again, this is clearly stated in WhatsApp's privacy policy and terms of use. "We may use the information we receive from [other Meta companies], and they may use the information we share with them, to help operate, provide, improve, understand, customize, support, and market our Services and their offerings," reads the policy. This means that yes, your messages are always private, but WhatsApp is actively collecting your metadata to build your digital persona across other Meta platforms...

The article suggests using a VPN with WhatsApp and turning on its "advanced privacy feature" (which hides your IP address during calls) and managing the app's permissions for data collection. "While these steps can help reduce the amount of metadata collected, it's crucial to bear in mind that it's impossible to completely avoid metadata collection on the Meta-owned app... For extra privacy and security, I suggest switching to the more secure messaging app Signal."

The article also includes a cautionary anecdote. "It was exactly a piece of metadata — a Proton Mail recovery email — that led to the arrest of a Catalan activist."

Top Broadband Official Exits Commerce Department With Warning About Starlink (politico.com) 183

An anonymous reader quotes a report from Politico: A top Commerce Department official sent a blistering email to his former colleagues on his way out the door Sunday warning that the Trump administration is poised to unduly enrich Elon Musk's satellite internet company with money for rural broadband. The technology offered by Starlink ... is inferior, wrote Evan Feinman, who had directed the $42.5 billion broadband program for the past three years. "Stranding all or part of rural America with worse internet so that we can make the world's richest man even richer is yet another in a long line of betrayals by Washington," Feinman said.

Feinman's lengthy email, totaling more than 1,100 words and shared with POLITICO, is a sign of deep discomfort about the changes underway that will likely transform the Broadband Equity, Access and Deployment Program. Commerce Secretary Howard Lutnick recently pledged a vigorous review of BEAD, with an aim to rip out what he sees as extraneous requirements and remove any preference for particular broadband technologies like fiber. The program, created in the 2021 infrastructure law program, became a source of partisan fighting last year on the campaign trail as Republicans attacked the Biden administration for its slow pace. No internet expansion projects have begun using BEAD money, although some states were close at the beginning of this year. Feinman's critique: In his email, Feinman notes Friday was his last day leading BEAD and that he's "disappointed not to be able to see this project through."

Feinman's email warns the Trump administration could undermine BEAD and he encourages people to fight to retain its best aspects. Feinman said the administration should "NOT change it to benefit technology that delivers slower speeds at higher costs to the household paying the bill," adding that this isn't what rural America, congressional Republicans or Democrats, the states or the telecom industry wants. "Reach out to your congressional delegation and reach out to the Trump Administration and tell them to strip out the needless requirements, but not to strip away from states the flexibility to get the best connections for their people," Feinman wrote. He said he's not worried about the Trump administration nixing requirements around climate resiliency, labor and middle class affordability, saying those issues "were inserted by the prior administration for messaging/political purposes, and were never central to the mission of the program."
Feinman warns that changes to the BEAD program under the Trump administration could stall state-level broadband progress, with Louisiana, Delaware, and Nevada already stuck in review.

Meanwhile, no specific guidance or timeline for these changes has been provided, and Arielle Roth's confirmation as NTIA head is still pending in the Senate.

Alphabet Spins Off Laser-Based Internet Project Taara From 'Moonshot' Unit (ft.com) 22

Alphabet is spinning out Taara, a laser-based internet company from its X "moonshot" incubator, securing backing from Series X Capital while retaining a minority stake.

Taara's technology transmits data at 20 gigabits per second over 20km by firing pencil-width light beams between traffic light-sized terminals, extending traditional fiber-optic networks with minimal construction costs.

Based in Sunnyvale, California, the company operates in 12 countries, including India and parts of Africa, where it created a 5km laser link over the Congo River between Brazzaville and Kinshasa. The two-dozen-strong team partners with telecommunications firms like Bharti Airtel and T-Mobile to extend core fiber-optic networks to remote locations or dense urban areas.

Taara originated from Project Loon, which was shut down in 2021 after facing regulatory challenges. The company is developing silicon photonic chips to replace mirrors and lenses in its terminals and potentially enable multiple connections from a single transmitter.

After Meta Blocks Whistleblower's Book Promotion, It Becomes an Amazon Bestseller (thetimes.com) 39

After Meta convinced an arbitrator to temporarily prevent a whistleblower from promoting their book about the company (titled: Careless People), the book climbed to the top of Amazon's best-seller list. And the book's publisher Macmillan released a defiant statement that "The arbitration order has no impact on Macmillan... We will absolutely continue to support and promote it." (They added that they were "appalled by Meta's tactics to silence our author through the use of a non-disparagement clause in a severance agreement.")

Saturday the controversy was even covered by Rolling Stone: [Whistleblower Sarah] Wynn-Williams is a diplomat, policy expert, and international lawyer, with previous roles including serving as the Chief Negotiator for the United Nations on biosafety liability, according to her bio on the World Economic Forum...

Since the book's announcement, Meta has forcefully responded to the book's allegations in a statement... "Eight years ago, Sarah Wynn-Williams was fired for poor performance and toxic behavior, and an investigation at the time determined she made misleading and unfounded allegations of harassment. Since then, she has been paid by anti-Facebook activists and this is simply a continuation of that work. Whistleblower status protects communications to the government, not disgruntled activists trying to sell books."

But the negative coverage continues, with the Observer Sunday highlighting it as their Book of the Week. "This account of working life at Mark Zuckerberg's tech giant organisation describes a 'diabolical cult' able to swing elections and profit at the expense of the world's vulnerable..."

Though ironically Wynn-Williams started their career with optimism about Facebook's role in the app internet.org. . "Upon witnessing how the nascent Facebook kept Kiwis connected in the aftermath of the 2011 Christchurch earthquake, she believed that Mark Zuckerberg's company could make a difference — but in a good way — to social bonds, and that she could be part of that utopian project...

What internet.org involves for countries that adopt it is a Facebook-controlled monopoly of access to the internet, whereby to get online at all you have to log in to a Facebook account. When the scales fall from Wynn-Williams's eyes she realises there is nothing morally worthwhile in Zuckerberg's initiative, nothing empowering to the most deprived of global citizens, but rather his tool involves "delivering a crap version of the internet to two-thirds of the world". But Facebook's impact in the developing world proves worse than crap. In Myanmar, as Wynn-Williams recounts at the end of the book, Facebook facilitated the military junta to post hate speech, thereby fomenting sexual violence and attempted genocide of the country's Muslim minority. "Myanmar," she writes with a lapsed believer's rue, "would have been a better place if Facebook had not arrived." And what is true of Myanmar, you can't help but reflect, applies globally...

"Myanmar is where Wynn-Williams thinks the 'carelessness' of Facebook is most egregious," writes the Sunday Times: In 2018, UN human rights experts said Facebook had helped spread hate speech against Rohingya Muslims, about 25,000 of whom were slaughtered by the Burmese military and nationalists. Facebook is so ubiquitous in Myanmar, Wynn-Williams points out, that people think it is the entire internet. "It's no surprise that the worst outcome happened in the place that had the most extreme take-up of Facebook." Meta admits it was "too slow to act" on abuse in its Myanmar services....

After Wynn-Williams left Facebook, she worked on an international AI initiative, and says she wants the world to learn from the mistakes we made with social media, so that we fare better in the next technological revolution. "AI is being integrated into weapons," she explains. "We can't just blindly wander into this next era. You think social media has turned out with some issues? This is on another level."

NAB Calls For End of ATSC 1.0 (broadbandtvnews.com) 47

An anonymous reader quotes a report from Broadband TV News: The National Association of Broadcasters (NAB) has filed a petition with the Federal Communications Commission (FCC) urging the agency to establish a clear, industry-wide transition plan for the full deployment of Next Gen TV (ATSC 3.0). The proposal outlines a two-phased transition while modernizing regulatory requirements to support consumer access and innovation. [...] Under the plan, stations in the top 55 markets, covering 70% of the US population, would transition by February 2028, with all remaining full-power and Class A stations following in or before February 2030. The petition also calls for updates to FCC rules to ensure television reception devices support Next Gen TV, maintain existing MVPD carriage obligations and eliminate regulatory hurdles that could slow adoption. To clarify, ATSC 1.0 is the current standard for free over-the-air (OTA) TV. While ATSC 3.0 (also called NextGen TV) is its intended replacement, it's not backward-compatible, meaning consumers need new equipment to receive it. NAB's petition is to allow a complete shutdown of ATSC 1.0 to accelerate the transition to ATSC 3.0, meaning older TV setups relying on free OTA signals would stop working unless consumers upgrade their equipment. Their argument is that ATSC 3.0 adoption has been slow, and networks would benefit more from shifting away from OTA broadcasting entirely.

Reddit user bshensky argues that shutting down OTA TV would benefit large media corporations and harm independent stations. It's also worth noting that OTA TV operates on valuable spectrum, which could be repurposed for mobile broadband (this has happened before), benefiting cellular providers.

Leaked Apple Meeting Shows How Dire the Siri Situation Really Is (theverge.com) 51

A leaked Apple meeting reveals significant internal struggles with Siri's development, as AI-powered features announced last June have been delayed and may not make it into iOS 19. The Verge reports: Bloomberg (paywalled) has the full scoop on what happened at a Siri team meeting led by senior director Robby Walker, who oversees the division. He called the delay an "ugly" situation and sympathized with employees who might be feeling burned out or frustrated by Apple's decisions and Siri's still-lackluster reputation. He also said it's not a given that the missing Siri features will make it into iOS 19 this year; that's the company's current target, but "doesn't mean that we're shipping then," he told employees. "We have other commitments across Apple to other projects," Walker said, according to Bloomberg's report. "We want to keep our commitments to those, and we understand those are now potentially more timeline-urgent than the features that have been deferred."

The meeting also hinted at tension between Apple's Siri unit and the marketing division. Walker said the communications team wanted to highlight features like Siri understanding personal context and being able to take action based on what's currently on a user's screen -- even though they were nowhere near ready. Those WWDC teases and the resulting customer expectations only made matters worse, Walker acknowledged. Apple has since pulled an iPhone 16 ad that showcased the features and has added disclaimers to several areas of its website noting they've all been punted to a TBD date. They were held back in part due to quality issues "that resulted in them not working properly up to a third of the time," according to Mark Gurman.

[...] Walker told his staff that senior executives like software chief Craig Federighi and AI boss John Giannandrea are taking "intense personal accountability" for a predicament that's drawing fierce criticism as the months pass by with little to show for it beyond a prettier Siri animation. "Customers are not expecting only these new features but they also want a more fully rounded-out Siri," Walker said. "We're going to ship these features and more as soon as they are ready." He praised the team for its "incredibly impressive" work so far. "These are not quite ready to go to the general public, even though our competitors might have launched them in this state or worse," he said of the delayed features.

T-Mobile Raising Rates for More Legacy Customers (cnet.com) 45

After raising rates last June for customers on some of its older plans, T-Mobile is pushing up costs again -- but it's not entirely clear how many people are affected. From a report: According to a memo obtained by CNET and sent to T-Mobile employees early this morning, some people will see a $5 per-line increase beginning with their April or May bills.

The memo by Jon Freier, president of T-Mobile's consumer group, states that customers affected by the price hike should be notified by the end of today, March 13. Only those who receive a notice will see the rate increase.

Freier cites the "rising costs over the past several years" as the impetus behind the price push. Other carriers are facing the same headwinds, such as Verizon last December and this January, and AT&T last January and June.

Supercomputer Draws Molecular Blueprint For Repairing Damaged DNA (phys.org) 10

Using the Summit supercomputer at the Department of Energy's Oak Ridge National Laboratory, researchers have modeled a key component of nucleotide excision repair (NER) called the pre-incision complex (PInC), which plays a crucial role in DNA damage repair. Their study, published in Nature Communications, provides new insights into how the PInC machinery orchestrates precise DNA excision, potentially leading to advancements in treating genetic disorders, preventing premature aging, and understanding conditions like xeroderma pigmentosum and Cockayne syndrome. Phys.Org reports: "Computationally, once you assemble the PInC, molecular dynamics simulations of the complex become relatively straightforward, especially on large supercomputers like Summit," [said lead investigator Ivaylo Ivanov, a chemistry professor at Georgia State University]. Nanoscale Molecular Dynamics, or NAMD, is a molecular dynamics code specifically designed for supercomputers and is used to simulate the movements and interactions of large biomolecular systems that contain millions of atoms. Using NAMD, the research team ran extensive simulations. The number-crunching power of the 200-petaflop Summit supercomputer -- capable of performing 200,000 trillion calculations per second -- was essential in unraveling the functional dynamics of the PInC complex on a timescale of microseconds. "The simulations showed us a lot about the complex nature of the PInC machinery. It showed us how these different components move together as modules and the subdivision of this complex into dynamic communities, which form the moving parts of this machine," Ivanov said.

The findings are significant in that mutations in XPF and XPG can lead to severe human genetic disorders. They include xeroderma pigmentosum, which is a condition that makes people more susceptible to skin cancer, and Cockayne syndrome, which can affect human growth and development, lead to impaired hearing and vision, and speed up the aging process. "Simulations allow us to zero in on these important regions because mutations that interfere with the function of the NER complex often occur at community interfaces, which are the most dynamic regions of the machine," Ivanov said. "Now we have a much better understanding of how and from where these disorders manifest."

SpaceX Readies Starlink India Launch 32

SpaceX's Starlink has secured its first agreement in India, partnering with telecommunications leader Bharti Airtel to bring high-speed satellite internet to the world's most populous country, the companies announced Tuesday [PDF].

The landmark deal will enable Starlink to tap into Airtel's extensive retail network and ground infrastructure while expanding its global reach into previously underserved regions across India, pending regulatory authorizations.

"We are excited to work with Airtel and unlock the transformative impact Starlink can bring to the people of India," said Gwynne Shotwell, President and Chief Operating Officer of SpaceX. "The team at Airtel has played a pivotal role in India's telecom story, so working with them to complement our direct offering makes great sense for our business."

The collaboration will explore selling Starlink equipment through Airtel's retail stores and offering services to business customers while connecting communities in rural areas with limited connectivity.

Axiom Space and Red Hat Will Bring Edge Computing to the International Space Station (theregister.com) 7

Axiom Space and Red Hat will collaborate to launch Data Center Unit-1 (AxDCU-1) to the International Space Station this spring. It's a small data processing prototype (powered by lightweight, edge-optimized Red Hat Device Edge) that will demonstrate initial Orbital Data Center (ODC) capabilities.

"It all sounds rather grand for something that resembles a glorified shoebox," reports the Register. Axiom Space said: "The prototype will test applications in cloud computing, artificial intelligence, and machine learning (AI/ML), data fusion and space cybersecurity."

Space is an ideal environment for edge devices. Connectivity to datacenters on Earth is severely constrained, so the more processing that can be done before data is transmitted to a terrestrial receiving station, the better. Tony James, chief architect, Science and Space at Red Hat, said: "Off-planet data processing is the next frontier, and edge computing is a crucial component. With Red Hat Device Edge and in collaboration with Axiom Space, Earth-based mission partners will have the capabilities necessary to make real-time decisions in space with greater reliability and consistency...."

The Red Hat Device Edge software used by Axiom's device combines Red Hat Enterprise Linux, the Red Hat Ansible Platform, and MicroShift, a lightweight Kubernetes container orchestration service derived from Red Hat OpenShift. The plan is for Axiom Space to host hybrid cloud applications and cloud-native workloads on-orbit. Jason Aspiotis, global director of in-space data and security, Axiom Space, told The Register that the hardware itself is a commercial off-the-shelf unit designed for operation in harsh environments... "AxDCU-1 will have the ability to be controlled and utilized either via ground-to-space or space-to-space communications links. Our current plans are to maintain this device on the ISS. We plan to utilize this asset for at least two years."

The article notes that HPE has also "sent up a succession of Spaceborne computers — commercial, off-the-shelf supercomputers — over the years to test storage, recovery, and operational potential on long-duration missions." (They apparently use Red Hat Enterprise Linux.) "At the other end of the scale, the European Space Agency has run Raspberry Pi computers on the ISS for years as part of the AstroPi educational outreach program."

Axiom Space says their Orbital Data Center is deigned to "reduce delays traditionally associated with orbital data processing and analysis." By utilizing Earth-independent cloud storage and edge processing infrastructure, Axiom Space ODCs will enable data to be processed closer to its source, spacecraft or satellites, bypassing the need for terrestrial-based data centers. This architecture alleviates reliance on costly, slow, intermittent or contested network connections, creating more secure and quicker decision-making in space.

The goal is to allow Axiom Space and its partners to have access to real-time processing capabilities, laying the foundation for increased reliability and improved space cybersecurity with extensive applications. Use cases for ODCs include but are not limited to supporting Earth observation satellites with in-space and lower latency data storage and processing, AI/ML training on-orbit, multi-factor authentication and cyber intrusion detection and response, supervised autonomy, in-situ space weather analytics and off-planet backup & disaster recovery for critical infrastructure on Earth.

Rayhunter: A Cheap New Tool from EFF to Detect Cellular Spying (androidauthority.com) 23

Equuleus42 (Slashdot reader #723) brings word that the Electronic Frontier Foundation (EFF) is sharing a new tool for fighting back against cellphone surveillance by Stingray cell-site simulators.

Android Authority reports: "Rayhunter" uses an open-source software package designed to look for evidence of IMSI catchers in action, running on an old Orbic Speed RC400L mobile hotspot. The great thing about that choice is that you can pick one up for practically nothing — we're seeing them listed for barely over $10 on Amazon, and you can find them even cheaper on eBay. There's an installation script for Macs and Linux to automate getting set up, but once the Orbic is flashed with the Rayhunter software, it should be ready go, collecting data about sketchy-looking "cell towers" it picks up.

Right now, much of the use of IMSI catchers is still shrouded in mystery, with the groups who regularly employ them extremely hesitant to disclose their methods. As a result, a big focus of this EFF project is just getting more info on how and where these are actually used, giving protestors a better sense of the steps they'll need to take if they want to protect their privacy.

Why Most Countries Are Struggling To Shut Down 2G (restofworld.org) 56

Global telecom operators are struggling to shut down aging 2G networks despite pressure to free up spectrum for 4G and 5G services, as the transition threatens to exclude millions of vulnerable users.

While Vietnam successfully decommissioned 2G in November 2024 by providing free 4G phones to low-income users, countries like South Africa and India have delayed shutdowns over concerns about cutting off phone access for millions. According to GSMA Intelligence, 61 countries have planned or initiated 2G network shutdowns to enhance bandwidth and reduce maintenance costs. For 2.5 billion people worldwide, smartphones cost about 30% of monthly income, keeping basic phones essential despite declining global feature phone sales.

US House Panel Subpoenas Alphabet Over Content Moderation (yahoo.com) 40

An anonymous reader quotes a report from Reuters: The U.S. House Judiciary Committee subpoenaed Alphabet on Thursday seeking its communications with former President Joe Biden's administration about content moderation policies. House Judiciary Committee Chairman Jim Jordan, a Republican, also asked the YouTube parent company for similar communications with companies and groups outside government, according to a copy of the subpoena seen by Reuters. The subpoena seeks communications about limits or bans on content about President Donald Trump, Tesla CEO and close Trump ally Elon Musk, the virus that causes COVID-19 and a host of other conservative discussion topics. "Alphabet, to our knowledge, has not similarly disavowed the Biden-Harris Administration's attempts to censor speech," Jordan said in a letter.

Meanwhile, Google spokesperson Jose Castaneda said the company will "continue to show the committee how we enforce our policies independently, rooted in our commitment to free expression."

Starlink Benefits As Trump Admin Rewrites Rules For $42 Billion Grant Program (arstechnica.com) 163

An anonymous reader quotes a report from Ars Technica: The Trump administration is eliminating a preference for fiber Internet in a $42.45 billion broadband deployment program, a change that is expected to reduce spending on the most advanced wired networks while directing more money to Starlink and other non-fiber Internet service providers. One report suggests Starlink could obtain $10 billion to $20 billion under the new rules. Secretary of Commerce Howard Lutnick criticized the Biden administration's handling of the Broadband Equity, Access, and Deployment (BEAD) program in a statement yesterday. Lutnick said that "because of the prior Administration's woke mandates, favoritism towards certain technologies, and burdensome regulations, the program has not connected a single person to the Internet and is in dire need of a readjustment."

The BEAD program was authorized by Congress in November 2021, and the US was finalizing plans to distribute funding before Trump's inauguration. The National Telecommunications and Information Administration (NTIA), part of the Commerce Department, developed rules for the program in the Biden era and approved initial funding plans submitted by every state and territory. The program has been on hold since the change in administration, with Senator Ted Cruz (R-Texas) and other Republicans seeking rule changes. In addition to demanding an end to the fiber preference, Cruz wants to kill a requirement that ISPs receiving network-construction subsidies provide cheap broadband to people with low incomes. Cruz also criticized "unionized workforce and DEI labor requirements; climate change assessments; excessive per-location costs; and other central planning mandates."

Lutnick's statement yesterday confirmed that the Trump administration will end the fiber preference and replace it with a "tech-neutral" set of rules, and explore additional changes. He said: "Under my leadership, the Commerce Department has launched a rigorous review of the BEAD program. The Department is ripping out the Biden Administration's pointless requirements. It is revamping the BEAD program to take a tech-neutral approach that is rigorously driven by outcomes, so states can provide Internet access for the lowest cost. Additionally, the Department is exploring ways to cut government red tape that slows down infrastructure construction. We will work with states and territories to quickly get rid of the delays and the waste. Thereafter we will move quickly to implementation in order to get households connected." Lutnick said the department's goal is to "deliver high-speed Internet access... efficiently and effectively at the lowest cost to taxpayers."

US Communications Agency To Explore Alternatives To GPS Systems (reuters.com) 57

The FCC says it plans to vote next month to explore alternatives to GPS after national security concerns have been raised about relying on a single system crucial to modern life. From a report: "Continuing to rely so heavily on one system leaves us exposed," FCC Chair Brendan Carr said. "We need to develop redundant technologies." There have been reports of a rise in GPS interference around the world, particularly since 2023, known as spoofing raising fears of an increased risk of accidents if planes veer off-course. "Disruptions to GPS have the potential to undermine the nation's economic and national security. And the risks to our current system are only increasing," Carr said, noting President Donald Trump and a bipartisan group of lawmakers have called for action for years.

NASA Uses GPS On the Moon For the First Time (popsci.com) 30

An anonymous reader quotes a report from Popular Science: On March 2, Firefly Aerospace's Blue Ghost made history, becoming the first commercial lunar lander to successfully touchdown on the moon's surface. The groundbreaking lander is wasting no time in getting to work. According to NASA, the joint public-private mission has already successfully demonstrated the ability to use Earth-based GPS signals on the lunar surface, marking a major step ahead of future Artemis missions. Accurate and reliable navigation will be vital for future astronauts as they travel across the moon, but traditional GPS tools aren't much good when you're around 225,000 miles from Earth. One solution could be transmitting data from the Global Navigation Satellite System (GNSS) to the lunar surface in order to autonomously measure time, velocity, and position. That's what mission engineers from NASA and the Italian Space Agency hoped to demonstrate through the Lunar GNSS Receiver Experiment (LuGRE), one of the 10 projects packed aboard Blue Ghost. [...]

"On Earth we can use GNSS signals to navigate in everything from smartphones to airplanes," Kevin Coggins, deputy associate administrator for NASA's SCaN (Space Communications and Navigation) Program, said in a statement. "Now, LuGRE shows us that we can successfully acquire and track GNSS signals at the Moon." LuGRE relied on two GNSS constellations, GPS and Galileo, which triangulate positioning based on dozens of medium Earth orbit satellites that provide real-time tracking data. It performed its navigational fix at approximately 2 a.m. EST on March 3, while about 225,000 miles from Earth. Blue Ghost's LuGRE system will continue collecting information over the next two weeks almost continuously while the lander's other tools begin their own experiments.

Researchers Find Less-Educated Areas Adopting AI Writing Tools Faster 108

An anonymous reader quotes a report from Ars Technica: Since the launch of ChatGPT in late 2022, experts have debated how widely AI language models would impact the world. A few years later, the picture is getting clear. According to new Stanford University-led research examining over 300 million text samples across multiple sectors, AI language models now assist in writing up to a quarter of professional communications across sectors. It's having a large impact, especially in less-educated parts of the United States. "Our study shows the emergence of a new reality in which firms, consumers and even international organizations substantially rely on generative AI for communications," wrote the researchers.

The researchers tracked large language model (LLM) adoption across industries from January 2022 to September 2024 using a dataset that included 687,241 consumer complaints submitted to the US Consumer Financial Protection Bureau (CFPB), 537,413 corporate press releases, 304.3 million job postings, and 15,919 United Nations press releases. By using a statistical detection system that tracked word usage patterns, the researchers found that roughly 18 percent of financial consumer complaints (including 30 percent of all complaints from Arkansas), 24 percent of corporate press releases, up to 15 percent of job postings, and 14 percent of UN press releases showed signs of AI assistance during that period of time.

The study also found that while urban areas showed higher adoption overall (18.2 percent versus 10.9 percent in rural areas), regions with lower educational attainment used AI writing tools more frequently (19.9 percent compared to 17.4 percent in higher-education areas). The researchers note that this contradicts typical technology adoption patterns where more educated populations adopt new tools fastest. "In the consumer complaint domain, the geographic and demographic patterns in LLM adoption present an intriguing departure from historical technology diffusion trends where technology adoption has generally been concentrated in urban areas, among higher-income groups, and populations with higher levels of educational attainment."
"Arkansas showed the highest adoption rate at 29.2 percent (based on 7,376 complaints), followed by Missouri at 26.9 percent (16,807 complaints) and North Dakota at 24.8 percent (1,025 complaints)," notes Ars. "In contrast, states like West Virginia (2.6 percent), Idaho (3.8 percent), and Vermont (4.8 percent) showed minimal AI writing adoption. Major population centers demonstrated moderate adoption, with California at 17.4 percent (157,056 complaints) and New York at 16.6 percent (104,862 complaints)."

The study was listed on the arXiv preprint server in mid-February.

Microsoft Unveils New Voice-Activated AI Assistant For Doctors 18

Microsoft has introduced Dragon Copilot, a voice-activated AI assistant for doctors that integrates dictation and ambient listening tools to automate clinical documentation, including notes, referrals, and post-visit summaries. The tool is set to launch in May in the U.S. and Canada. CNBC reports: Microsoft acquired Nuance Communications, the company behind Dragon Medical One and DAX Copilot, for about $16 billion in 2021. As a result, Microsoft has become a major player in the fiercely competitive AI scribing market, which has exploded in popularity as health systems have been looking for tools to help address burnout. AI scribes like DAX Copilot allow doctors to draft clinical notes in real time as they consensually record their visits with patients. DAX Copilot has been used in more than 3 million patient visits across 600 health-care organizations in the last month, Microsoft said.

Dragon Copilot is accessible through a mobile app, browser or desktop, and it integrates directly with several different electronic health records, the company said. Clinicians will still be able to draft clinical notes with the assistant like they could with DAX Copilot, but they'll be able to use natural language to edit their documentation and prompt it further, Kenn Harper, general manager of Dragon products at Microsoft, told reporters on the call. For instance, a doctor could ask questions like, "Was the patient experiencing ear pain?" or "Can you add the ICD-10 codes to the assessment and plan?" Physicians can also ask broader treatment-related queries such as, "Should this patient be screened for lung cancer?" and get an answer with links to resources like the Centers for Disease Control and Prevention.

Fast New 3D Printing Technique Shines Holograms into Resin (3dprintingindustry.com) 14

Can a new 3D-printing technique shorten 3D printing times to just seconds? A team of researchers in Europe has modified Tomographic Volumetric Additive Manufacturing, which can "create entire objects in one shot by shining light patterns into liquid resin," according to the 3D Printing Industry blog. (The liquid resin then solidifies when the light intensity is high enough...) While this approach can fabricate support-free, micro-scale parts within tens of seconds, it is "highly inefficient." This is because under 1% of the encoded light reaches the resin vial. Conventional TVAM can also lead to unwanted distortions and poor resolution due to light blurring and projection artifacts. To address these limitations, the researchers developed HoloVAM, a new technique that uses a 3D hologram instead of conventional volumetric light projections. This approach reportedly boosts light efficiency by 20 times, resulting in faster and more accurate 3D printing.

According to their paper, published in Nature Communications, HoloVAM successfully fabricated several millimeter-scale objects in under 60 seconds with fine details as small as 31 micrometers...

They believe this new approach offers value for medical bioprinting applications, thanks to HoloVAM's use of "self-healing beams." These can generate and retain their shape when passing through materials, which is particularly valuable when 3D printing with cell-laden bio-resins and hydrogels.

Tesla Moves Towards Launching an Uber Competitor (axios.com) 245

"Tesla is taking steps to launch a ride-sharing service that could compete directly with Uber, Lyft and Waymo," reports Axios, noting that Tesla "has filed for a transportation charter-party carrier permit from the California Public Utilities Commission, Bloomberg reported Thursday." "That classification means Tesla would own and control the fleet of vehicles," Bloomberg reported... "In its communications with California officials, Tesla discussed driver's license information and drug-testing coordination, suggesting the company intends to use human drivers, at least initially," Bloomberg reported. The company is seeking the same type of permit that Waymo uses to run its robotaxi business.Uber is gearing up to begin offering autonomous vehicle services in partnership with Waymo in Austin and Atlanta later this year.
The article also adds that Musk "told investors in January that 'I'm confident that we will release unsupervised FSD in California this year,' referring to the company's Full Self-Driving system." But "Tesla has yet to apply for a permit to operate driverless vehicles..." notes the EV blog Electrek, adding "This is just a step for Tesla to test ride-hailing services ahead of autonomy."

Reuters also points out that "Earlier in October, Tesla revealed the Cybercab, a robotaxi concept that had no steering wheel or control pedals... He has said the Cybercab will go into production in 2026 and will also be available for customers to buy for less than $30,000."
