Were DeepSeek's Development Costs Much Higher Than Reported? (msn.com) 49

Nearly three years ago a team of Chinese AI engineers working for DeepSeek's parent company unveiled an earlier AI supercomputer that the Washington Post says was constructed from 10,000 A100 GPUs purchased from Nvidia. Roughly six months later "Washington had banned Nvidia from selling any more A100s to China," the article notes.

Remember that number as you read this. 10,000 A100 GPUs... DeepSeek's new chatbot caused a panic in Silicon Valley and on Wall Street this week, erasing $1 trillion from the stock market. That impact stemmed in large part from the company's claim that it had trained one of its recent models on a minuscule $5.6 million in computing costs and with only 2,000 or so of Nvidia's less-advanced H800 chips.

Nvidia saw its soaring value crater by $589 billion Monday as DeepSeek rocketed to the top of download charts, prompting President Donald Trump to call for U.S. industry to be "laser focused" on competing... But a closer look at DeepSeek reveals that its parent company deployed a large and sophisticated chip set in its supercomputer, leading experts to assess the total cost of the project as much higher than the relatively paltry sum that U.S. markets reacted to this week... Lennart Heim, an AI expert at Rand, said DeepSeek's evident access to [the earlier] supercomputer would have made it easier for the company to develop a more efficient model, requiring fewer chips.

That earlier project "suggests that DeepSeek had a major boost..." according to the article, "with technology comparable to that of the leading U.S. AI companies." And while DeepSeek claims it only spent $5.6 million to train one of its advanced models, "its parent company has said that building the earlier supercomputer had cost 1 billion yuan, or $139 million.") Yet the article also cites the latest insights Friday from chip investment company SemiAnalysis, summarizing their finding that DeepSeek "has spent more than half a billion dollars on GPUs, with total capital expenditures of almost $1.3 billion."

The article notes Thursday remarks by OpenAI CEO Sam Altman that DeepSeek's energy-efficiency claims were "wildly overstated... This is a model at a capability level that we had quite some time ago." And Palmer Luckey called DeepSeek "legitimately impressive" on X but called the $5.6 million training cost figure "bogus" and said the Silicon Valley meltdown was "hysteria." Even with these higher total costs in mind, experts say, U.S. companies are right to be concerned about DeepSeek upending the market. "We know two things for sure: DeepSeek is pricing their services very competitively, and second, the performance of their models is comparable to leading competitors," said Kai-Shen Huang, an AI expert at the Research Institute for Democracy, Society and Emerging Technology, a Taipei-based think tank. "I think DeepSeek's pricing strategy has the potential to disrupt the market globally...."

China's broader AI policy push has helped create an environment conducive for a company like DeepSeek to rise. Beijing announced an ambitious AI blueprint in 2017, with a goal to become a global AI leader by 2030 and promises of funding for universities and private enterprise. Local governments across the nation followed with their own programs to support AI.

Quantum Computer Built On Server Racks Paves the Way To Bigger Machines (technologyreview.com) 27

An anonymous reader quotes a report from MIT Technology Review: A Canadian startup called Xanadu has built a new quantum computer it says can be easily scaled up to achieve the computational power needed to tackle scientific challenges ranging from drug discovery to more energy-efficient machine learning. Aurora is a "photonic" quantum computer, which means it crunches numbers using photonic qubits -- information encoded in light. In practice, this means combining and recombining laser beams on multiple chips using lenses, fibers, and other optics according to an algorithm. Xanadu's computer is designed in such a way that the answer to an algorithm it executes corresponds to the final number of photons in each laser beam. This approach differs from one used by Google and IBM, which involves encoding information in properties of superconducting circuits.

Aurora has a modular design that consists of four similar units, each installed in a standard server rack that is slightly taller and wider than the average human. To make a useful quantum computer, "you copy and paste a thousand of these things and network them together," says Christian Weedbrook, the CEO and founder of the company. Ultimately, Xanadu envisions a quantum computer as a specialized data center, consisting of rows upon rows of these servers. This contrasts with the industry's earlier conception of a specialized chip within a supercomputer, much like a GPU. [...]

Xanadu's 12 qubits may seem like a paltry number next to IBM's 1,121, but Tiwari says this doesn't mean that quantum computers based on photonics are running behind. In his opinion, the number of qubits reflects the amount of investment more than it does the technology's promise. [...] Xanadu's next goal is to improve the quality of the photons in the computer, which will ease the error correction requirements. "When you send lasers through a medium, whether it's free space, chips, or fiber optics, not all the information makes it from the start to the finish," he says. "So you're actually losing light and therefore losing information." The company is working to reduce this loss, which means fewer errors in the first place. Xanadu aims to build a quantum data center, with thousands of servers containing a million qubits, in 2029.
The company published its work on chip design optimization and fabrication in the journal Nature.

Commercial Tea Bags Release Millions of Microplastics, Entering Human Intestinal Cells 108

A new study finds that polymer-based commercial tea bags release billions of nanoplastics and microplastics when infused. It also shows for the first time that these particles are capable of being absorbed by human intestinal cells, entering the bloodstream, and potentially affecting human health. The study by the Mutagenesis Group of the UAB Department of Genetics and Microbiology has been published in the journal Chemosphere. Medical Xpress reports: The tea bags used for the research were made from the polymers nylon-6, polypropylene and cellulose. The study shows that, when brewing tea, polypropylene releases approximately 1.2 billion particles per milliliter, with an average size of 136.7 nanometers; cellulose releases about 135 million particles per milliliter, with an average size of 244 nanometers; while nylon-6 releases 8.18 million particles per milliliter, with an average size of 138.4 nanometers. To characterize the different types of particles present in the infusion, a set of advanced analytical techniques such as scanning electron microscopy (SEM), transmission electron microscopy (TEM), infrared spectroscopy (ATR-FTIR), dynamic light scattering (DLS), laser Doppler velocimetry (LDV), and nanoparticle tracking analysis (NTA) were used.

The particles were stained and exposed for the first time to different types of human intestinal cells to assess their interaction and possible cellular internalization. The biological interaction experiments showed that mucus-producing intestinal cells had the highest uptake of micro and nanoplastics, with the particles even entering the cell nucleus that houses the genetic material. The result suggests a key role for intestinal mucus in the uptake of these pollutant particles and underscores the need for further research into the effects that chronic exposure can have on human health.

SpaceX's Thursday Launch Enables Starlink's New Satellite-to-Cellphone Internet Service (newatlas.com) 50

"SpaceX has launched 20 of its Starlink satellites up into Earth's orbit, enabling direct-to-cellphone connectivity for subscribers anywhere on the planet," reports the tech blog New Atlas. That completes the constellation's first orbital shell, following a launch of an initial batch of six satellites for testing back in January. The satellites were launched with a Falcon 9 rocket from California's Vandenberg Space Force Base on December 5 at 10 PM EST; they were then deployed in low Earth orbit. SpaceX founder Elon Musk noted on X that the effort will "enable unmodified cellphones to have internet connectivity in remote areas." He added a caveat for the first orbital shell — "Bandwidth per beam is only ~10 Mb, but future constellations will be much more capable...."

The big deal with this new venture is that unlike previous attempts at providing satellite-to-phone service, you don't need a special handset or even a specific app to get access anywhere in the world. Starlink uses standard LTE/4G protocols that most phones are compatible with, partners with mobile operators like T-Mobile in the U.S. and Rogers in Canada, and has devised a system to make its service work seamlessly with your phone when it's connecting to satellites 340 miles (540 km) above the Earth's surface. The SpaceX division noted it's also worked out latency constraints, ideal altitudes and elevation angles for its satellites, along with several other parameters, to achieve reliable connectivity. Each satellite has an LTE modem on board, and these satellites plug into the massive constellation of 6,799 existing Starlink spacecraft, according to Space.com.

Connecting to that larger constellation happens via laser backhaul, where laser-based optical communication systems transmit data between satellites. This method leverages the advantages of lasers over traditional radio frequency communications, enabling data rates up to 100 times faster, increased bandwidth, and improved security.

The direct-to-cell program was approved last month, the article points out — but it's ready to ramp up. "You'll currently get only text service through the end of 2024; voice and data will become available sometime next year, as will support for IoT devices (such as smart home gadgets). The company hasn't said how much its service will cost. " (They also note there's already competing services from Lynk, "which has satellites in orbit and launched in the island nation of Palau back in 2023, and AST SpaceMobile, which also has commercial satellites in orbit and contracts with the U.S. government, Europe, and Japan.")

Elon Musk's announcement on X.com prompted this interesting exchange:

X.com User: You've stated that purchasing Starlink goes toward funding the journey to Mars, yes?

Elon Musk: Yes.

NASA Investigates Laser-Beam Welding in a Vacuum for In-Space Manufacturing (nasa.gov) 41

NASA hopes to stimulate in-space manufacturing through a multi-year "laser beam welding collaboration" with Ohio State University. The project "seeks to understand the physical processes of welding on the lunar surface," according to NASA.gov, "such as investigating the effects of laser beam welding in a combined vacuum and reduced gravity environment." The goal is to increase the capabilities of manufacturing in space to potentially assemble large structures or make repairs on the Moon, which will inform humanity's next giant leap of sending astronauts to Mars and beyond. "For a long time, we've used fasteners, rivets, or other mechanical means to keep structures that we assemble together in space," said Andrew O'Connor, a Marshall materials scientist who is helping coordinate the collaborative effort and is NASA's technical lead for the project. "But we're starting to realize that if we really want strong joints and if we want structures to stay together when assembled on the lunar surface, we may need in-space welding."

The ability to weld structures in space would also eliminate the need to transport rivets and other materials, reducing payloads for space travel. That means learning how welds will perform in space. To turn the effort into reality, researchers are gathering data on welding under simulated space conditions, such as temperature and heat transfer in a vacuum; the size and shape of the molten area under a laser beam; how the weld cross-section looks after it solidifies; and how mechanical properties change for welds performed in environmental conditions mimicking the lunar surface. "Once you leave Earth, it becomes more difficult to test how the weld performs, so we are leveraging both experiments and computer modeling to predict welding in space while we're still on the ground," said O'Connor.

In August 2024, a joint team from Ohio State's Welding Engineering and Multidisciplinary Capstone Programs and Marshall's Materials & Processes Laboratory performed high-powered fiber laser beam welding aboard a commercial aircraft that simulated reduced gravity. The aircraft performed parabolic flight maneuvers that began in level flight, pulled up to add 8,000 feet in altitude, and pushed over at the top of a parabolic arc, resulting in approximately 20 seconds of reduced gravity to the passengers and experiments. While floating in this weightless environment, team members performed laser welding experiments in a simulated environment similar to that of both low Earth orbit and lunar gravity. Analysis of data collected by a network of sensors during the tests will help researchers understand the effects of space environments on the welding process and welded material.

They performed that laser-beam welding in a vacuum chamber during the parabolic flight (on a Boeing 727), according to the article — and successfully completed 69 out of 70 welds in microgravity and lunar gravity conditions. "The last time NASA performed welding in space was during the Skylab mission in 1973...

"Practical welding and joining methods and allied processes, including additive manufacturing, will be required to develop the in-space economy."

Mozilla Foundation Lays Off 30% Staff, Drops Advocacy Division (techcrunch.com) 77

An anonymous reader quotes a report from TechCrunch: The Mozilla Foundation, the non-profit arm of the Firefox browser maker Mozilla, has laid off 30% of its employees as the organization says it faces a "relentless onslaught of change." When reached by TechCrunch, Mozilla Foundation's communications chief Brandon Borrman confirmed the layoffs in an email. "The Mozilla Foundation is reorganizing teams to increase agility and impact as we accelerate our work to ensure a more open and equitable technical future for us all. That unfortunately means ending some of the work we have historically pursued and eliminating associated roles to bring more focus going forward," read the statement shared with TechCrunch.

According to its annual tax filings, the Mozilla Foundation reported having 60 employees during the 2022 tax year. The number of employees at the time of the layoffs was closer to 120 people, according to a person with knowledge. When asked by TechCrunch, Mozilla's spokesperson did not dispute the figure. This is the second layoff at Mozilla this year, the first affecting dozens of employees who work on the side of the organization that builds the popular Firefox browser. [...] Announcing the layoffs in an email to all employees on October 30, the Mozilla Foundation's executive director Nabiha Syed confirmed that two of the foundation's major divisions -- advocacy and global programs -- are "no longer a part of our structure." The move, according to Syed, is in part to produce a "unified, powerful narrative from the Foundation," including revamping the foundation's strategic communications.
"Our mission at Mozilla is more high-stakes than ever," said Syed. "We find ourselves in a relentless onslaught of change in the technology (and broader) world, and the idea of putting people before profit feels increasingly radical."

"Navigating this topsy-turvy, distracting time requires laser focus -- and sometimes saying goodbye to the excellent work that has gotten us this far because it won't get us to the next peak. Lofty goals demand hard choices."

Royal Navy Successfully Tests Quantum-Sensing Technology (royalnavy.mod.uk) 25

An anonymous reader quotes a report from the Royal Navy: The Royal Navy has successfully demonstrated the capabilities of ground-breaking cold atom technology. P2000 vessel HMS Pursuer hosted the trial, which unlocks new possibilities in areas such as covert monitoring, which require precise signals for accurate positioning, navigation and timing. The Office of the Chief of Technology Officer (OCTO) for the RN worked with UK quantum technology company Aquark Technologies. The trial involved the company's miniature cold atom systems, founded on Aquark's unique laser-cooling method, known as supemolasses.

This method to generate cold atoms does not need an applied magnetic field, therefore reducing the size, weight, power consumption and cost of sensors. A cold atom is an atom that has been laser-cooled to extremely low temperatures, typically near absolute zero (-273.15C). At these temperatures, the thermal motion of atoms is very slow, allowing their quantum mechanical properties to be precisely controlled. Quantum Sensing is an advanced sensor technology that detects changes in motion, and electric and magnetic fields, by collecting data at the atomic level.
Commander Matthew Steele, who heads up Future Technology for OCTO, said: "Quantum technologies being developed in the UK will offer an alternative Position, Navigation and Timing (PNT) capability necessary to operate effectively in GPS denied or degraded environments."

"Over the next three years, the Navy seeks to accelerate the development of quantum technologies -- such as Aquarks -- through funding and sea trials, to secure the Royal Navy an opportunity to invest in a non-GPS-based PNT capability and to maintain its global operating advantage."

NASA Reveals Prototype Telescope For Gravitational Wave Observatory (phys.org) 14

NASA has revealed a full-scale prototype for six telescopes designed to detect gravitational waves. Phys.Org reports: The LISA (Laser Interferometer Space Antenna) mission is led by ESA (European Space Agency) in partnership with NASA to detect gravitational waves by using lasers to measure precise distances -- down to picometers, or trillionths of a meter -- between a trio of spacecraft distributed in a vast configuration larger than the sun. Each side of the triangular array will measure nearly 1.6 million miles, or 2.5 million kilometers.

The Engineering Development Unit Telescope, which was manufactured and assembled by L3Harris Technologies in Rochester, New York, arrived at Goddard in May. The primary mirror is coated in gold to better reflect the infrared lasers and to reduce heat loss from a surface exposed to cold space, since the telescope will operate best when close to room temperature.

The prototype is made entirely from an amber-colored glass-ceramic called Zerodur, manufactured by Schott in Mainz, Germany. The material is widely used for telescope mirrors and other applications requiring high precision because its shape changes very little over a wide range of temperatures. The LISA mission is slated to launch in the mid-2030s.

Startup Can Identify Deepfake Video In Real Time (wired.com) 28

An anonymous reader quotes a report from Wired: Real-time video deepfakes are a growing threat for governments, businesses, and individuals. Recently, the chairman of the US Senate Committee on Foreign Relations mistakenly took a video call with someone pretending to be a Ukrainian official. An international engineering company lost millions of dollars earlier in 2024 when one employee was tricked by a deepfake video call. Also, romance scams targeting everyday individuals have employed similar techniques. "It's probably only a matter of months before we're going to start seeing an explosion of deepfake video, face-to-face fraud," says Ben Colman, CEO and cofounder at Reality Defender. When it comes to video calls, especially in high-stakes situations, seeing should not be believing.

The startup is laser-focused on partnering with business and government clients to help thwart AI-powered deepfakes. Even with this core mission, Colman doesn't want his company to be seen as more broadly standing against artificial intelligence developments. "We're very pro-AI," he says. "We think that 99.999 percent of use cases are transformational -- for medicine, for productivity, for creativity -- but in these kinds of very, very small edge cases the risks are disproportionately bad." Reality Defender's plan for the real-time detector is to start with a plug-in for Zoom that can make active predictions about whether others on a video call are real or AI-powered impersonations. The company is currently working on benchmarking the tool to determine how accurately it discerns real video participants from fake ones. Unfortunately, it's not something you'll likely be able to try out soon. The new software feature will only be available in beta for some of the startup's clients.

As Reality Defender works to improve the detection accuracy of its models, Colman says that access to more data is a critical challenge to overcome -- a common refrain from the current batch of AI-focused startups. He's hopeful more partnerships will fill in these gaps, and without specifics, hints at multiple new deals likely coming next year. After ElevenLabs was tied to a deepfake voice call of US president Joe Biden, the AI-audio startup struck a deal with Reality Defender to mitigate potential misuse. [...] "We don't ask my 80-year-old mother to flag ransomware in an email," says Colman. "Because she's not a computer science expert." In the future, it's possible real-time video authentication, if AI detection continues to improve and shows to be reliably accurate, will be as taken for granted as that malware scanner quietly humming along in the background of your email inbox.

Starlink Is Now Available on All Hawaiian Airlines Airbus Flights (cnet.com) 36

Hot on the heels of United Airlines' Starlink announcement, Hawaiian Airlines said it, too, is offering "fast and free Starlink Wi-Fi" across its entire Airbus fleet. CNET reports: Hawaiian Airlines is now the first major carrier to use Elon Musk's satellite internet service, which taps more than 7,000 satellites in low earth orbit to deliver high-speed internet worldwide. "In Starlink's low earth orbit constellation of advanced satellites, the latest of which utilize a revolutionary laser mesh network, we found an ideal solution to ensure reliable, high-speed, low-latency Wi-Fi on transpacific flights," a Hawaiian Airlines representative told CNET. "Working with Starlink has allowed us to offer a fast and consistent in-flight connectivity experience that meets our high standard for guest service."

The company first debuted Starlink on its planes in February on a flight from Honolulu to Long Beach, California. It first struck a deal with Starlink in 2022 and has now completed installation across its entire Airbus fleet, which includes 24 A330 planes and 18 A321neos. Hawaiian Airlines will also deploy the service on its two Boeing 787-9 planes, but not its Boeing 717 aircraft, which are used on shorter flights between the Hawaiian Islands.

A Revolutionary Quantum Compass Could Soon Make GPS-Free Navigation a Reality (scitechdaily.com) 73

America's Department of Energy has three R&D labs, according to Wikipedia, one of which is Sandia National Labs. And that New Mexico-based lab has just announced that "A milestone in quantum sensing is drawing closer, promising exquisitely accurate, GPS-free navigation." with research into "a motion sensor so precise it could minimize the nation's reliance on global positioning satellites." Until recently, such a sensor — a thousand times more sensitive than today's navigation-grade devices — would have filled a moving truck. But advancements are dramatically shrinking the size and cost of this technology. For the first time, researchers from Sandia National Laboratories have used silicon photonic microchip components to perform a quantum sensing technique called atom interferometry, an ultra-precise way of measuring acceleration. It is the latest milestone toward developing a kind of quantum compass for navigation when GPS signals are unavailable. The team published its findings and introduced a new high-performance silicon photonic modulator — a device that controls light on a microchip — as the cover story in the journal Science Advances... The new modulator is the centerpiece of a laser system on a microchip. Rugged enough to handle heavy vibrations, it would replace a conventional laser system typically the size of a refrigerator...

Besides size, cost has been a major obstacle to deploying quantum navigation devices. Every atom interferometer needs a laser system, and laser systems need modulators. "Just one full-size single-sideband modulator, a commercially available one, is more than $10,000," said Sandia scientist Jongmin Lee. Miniaturizing bulky, expensive components into silicon photonic chips helps drive down these costs. "We can make hundreds of modulators on a single 8-inch wafer and even more on a 12-inch wafer," Kodigala said. And since they can be manufactured using the same process as virtually all computer chips, "This sophisticated four-channel component, including additional custom features, can be mass-produced at a much lower cost compared to today's commercial alternatives, enabling the production of quantum inertial measurement units at a reduced cost," Lee said.

As the technology gets closer to field deployment, the team is exploring other uses beyond navigation. Researchers are investigating whether it could help locate underground cavities and resources by detecting the tiny changes these make to Earth's gravitational force. They also see potential for the optical components they invented, including the modulator, in LIDAR, quantum computing, and optical communications.

NASA Fires Lasers At the ISS (theverge.com) 28

joshuark shares a report from The Verge: NASA researchers have successfully tested laser communications in space by streaming 4K video footage originating from an airplane in the sky to the International Space Station and back. The feat demonstrates that the space agency could provide live coverage of a Moon landing during the Artemis missions and bodes well for the development of optical communications that could connect humans to Mars and beyond. NASA normally uses radio waves to send data and talk between the surface to space but says that laser communications using infrared light can transmit data 10 to 100 times faster than radios. "ISS astronauts, cosmonauts, and unwelcomed commercial space-flight visitors can now watch their favorite porn in real-time, adding some life to a boring zero-G existence," adds joshuark. "Ralph Kramden, when contacted by Ouiji board, simply spelled out 'Bang, zoom, straight to the moon!'"

Mars Rover's SHELOC Instrument Back Online (nasa.gov) 14

Longtime Slashdot reader thephydes writes: NASA Jet Propulsion Laboratory (JPL) has announced that the SHERLOC (Scanning Habitable Environments with Raman & Luminescence for Organics and Chemicals) instrument on the Perseverance rover has been brought back online "Six months of running diagnostics, testing, imagery and data analysis, troubleshooting, and retesting couldn't come with a better conclusion," said SHERLOC principal investigator Kevin Hand of JPL.

JPL writes in a press release. "Mounted on the rover's robotic arm, SHERLOC uses cameras, spectrometers, and a laser to search for organics and minerals that have been altered by watery environments and may be signs of past microbial life." In addition to its black-and-white context camera, SHERLOC is assisted by WATSON, a color camera for taking close-up images of rock grains and surface textures.
The instrument stopped working this past January when it encountered an issue where the "movable lens cover designed to protect the instrument's spectrometer and one of its cameras from dust became frozen in a position that prevented SHERLOC from collecting data," says JPL.

"Analysis by the SHERLOC team pointed to the malfunction of a small motor responsible for moving the protective lens cover as well as adjusting focus for the spectrometer and the Autofocus and Context Imager (ACI) camera. By testing potential solutions on a duplicate SHERLOC instrument at JPL, the team began a long, meticulous evaluation process to see if, and how, the lens cover could be moved into the open position."

Lynn Conway, Leading Computer Scientist and Transgender Pioneer, Dies At 85 (latimes.com) 155

Lynn Conway, a pioneering computer scientist who made significant contributions to VLSI design and microelectronics, and a prominent advocate for transgender rights, died Sunday from a heart condition. She was 85. Pulitzer Prize-winning journalist Michael Hiltzik remembers Conway in a column for the Los Angeles Times: As I recounted in 2020, I first met Conway when I was working on my 1999 book about Xerox PARC, Dealers of Lightning, for which she was a uniquely valuable source. In 2000, when she decided to come out as transgender, she allowed me to chronicle her life in a cover story for the Los Angeles Times Magazine titled "Through the Gender Labyrinth." That article traced her journey from childhood as a male in New York's strait-laced Westchester County to her decision to transition. Years of emotional and psychological turmoil followed, even as he excelled in academic studies. [Conway earned bachelor's and master's degrees in electrical engineering from Columbia University in 1961, quickly joining a team at IBM to design the world's fastest supercomputer. Despite personal success, she faced significant emotional turmoil, leading to her decision to transition in 1968. Initially supportive, IBM ultimately fired Conway due to their inability to reconcile her transition with the company's conservative image.]

The family went on welfare for three months. Conway's wife barred her from contact with her daughters. She would not see them again for 14 years. Beyond the financial implications, the stigma of banishment from one of the world's most respected corporations felt like an excommunication. She sought jobs in the burgeoning electrical engineering community around Stanford, working her way up through start-ups, and in 1973 she was invited to join Xerox's brand new Palo Alto Research Center, or PARC. In partnership with Caltech engineering professor Carver Mead, Conway established the design rules for the new technology of "very large-scale integrated circuits" (or, in computer shorthand, VLSI). The pair laid down the rules in a 1979 textbook that a generation of computer and engineering students knew as "Mead-Conway."

VLSI fostered a revolution in computer microprocessor design that included the Pentium chip, which would power millions of PCs. Conway spread the VLSI gospel by creating a system in which students taking courses at MIT and other technical institutions could get their sample designs rendered in silicon. Conway's life journey gave her a unique perspective on the internal dynamics of Xerox's unique lab, which would invent the personal computer, the laser printer, Ethernet, and other innovations that have become fully integrated into our daily lives. She could see it from the vantage point of an insider, thanks to her experience working on IBM's supercomputer, and an outsider, thanks to her personal history.

After PARC, she was recruited to head a supercomputer program at the Defense Department's Advanced Research Projects Agency, or DARPA -- sailing through her FBI background check so easily that she became convinced that the Pentagon must have already encountered transgender people in its workforce. A figure of undisputed authority in some of the most abstruse corners of computing, Conway was elected to the National Academy of Engineering in 1989. She joined the University of Michigan as a professor and associate dean in the College of Engineering. In 2002 she married a fellow engineer, Charles Rogers, and with him lived active life -- with a shared passion for white-water canoeing, motocross racing and other adventures -- on a 24-acre homestead not far from Ann Arbor, Mich.
In 2020, Conway received a formal apology from IBM for firing her 52 years earlier. Diane Gherson, an IBM senior vice president, told her, "Thanks to your courage, your example, and all the people who followed in your footsteps, as a society we are now in a better place.... But that doesn't help you, Lynn, probably our very first employee to come out. And for that, we deeply regret what you went through -- and know I speak for all of us."

Dutch Police Test AI-Powered Robot Dog to Raid Drug Labs (interestingengineering.com) 29

"Police and search and rescue forces worldwide are increasingly using robots to assist in carrying out their operations," writes Interesting Engineering. "Now, the Dutch police are looking at employing AI-powered autonomous robot dogs in drug lab raids to protect officers from criminal risks, hazardous chemicals, and explosions."

New Scientist's Matthew Sparkes (also a long-time Slashdot reader) shares this report: Dutch police are planning to use an autonomous robotic dog in drug lab raids to avoid placing officers at risk from criminals, dangerous chemicals and explosions. If tests in mocked-up scenarios go well, the artificial intelligence-powered robot will be deployed in real raids, say police. Simon Prins at Politie Nederland, the Dutch police force, has been testing and using robots in criminal investigations for more than two decades, but says they are only now growing capable enough to be practical for more...
Some context from Interesting Engineering: The police force in the Netherlands carries out such raids at least three to four times a week... Since 2021, the force has already been using a Spot quadruped, fitted with a robotic arm, from Boston Dynamics to carry out drug raids and surveillance. However, the Spot is remotely controlled by a handler... [Significant technological advancements] have prompted the Dutch force to explore fully autonomous operations with Spot.

Reportedly, such AI-enabled autonomous robots are expected to inspect drug labs, ensure no criminals are present, map the area, and identify dangerous chemicals... Initial tests by force suggest that Spot could explore and map a mock drug lab measuring 15 meters by 20 meters. It was able to find hazardous chemicals and put them away into a designated storage container.

Their article notes that Spot "can do laser scans and visual, thermal, radiation, and acoustic inspections using add-on payloads and onboard cameras." (A video from Boston Dynamics — the company behind Spot — also seems to show the robot dog spraying something on a fire.)

The video seems aimed at police departments, touting the robot dog's advantages for "safety and incident response":
  • Enables safer investigation of suspicious packages
  • Detection of hazardous chemicals
  • De-escalation of tense or dangerous situations
  • Get eyes on dangerous situations

It also notes the robot "can be operated from a safe distance," suggesting customers "Use Spot® to place cameras, radios, and more for tactical reconnaissance."

Blacklisted Chinese Companies Rebrand as American To Dodge Crackdown (wsj.com) 46

American Lidar, a company registered in Michigan in December, is a subsidiary of China-based lidar maker Hesai Group, which the U.S. has labeled a security concern, WSJ reported Wednesday, citing policymakers and national-security experts. Chinese firms facing regulatory or reputational problems are rebranding and creating U.S.-domiciled businesses to sell their wares as the Biden administration expands the government entity lists that restrict Chinese companies' business dealings in the U.S., the report said.

These moves, while legal, irritate regulators who can't enforce laws when it isn't clear who is behind a company. Hesai became a target in the U.S.-China tech-trade war after allegations that its laser sensors could be used to collect sensitive American data, and was added to the Defense Department list that designates companies as Chinese military entities operating in the U.S. BGI Genomics and DJI are also facing similar challenges and are attempting to rebrand or license their technology to American startups to avoid sanctions.

Earthcare Cloud Mission Launches To Resolve Climate Unknowns (bbc.com) 25

An anonymous reader quotes a report from the BBC: A sophisticated joint European-Japanese satellite has launched to measure how clouds influence the climate. Some low-level clouds are known to cool the planet, others at high altitude will act as a blanket. The Earthcare mission will use a laser and a radar to probe the atmosphere to see precisely where the balance lies. It's one of the great uncertainties in the computer models used to forecast how the climate will respond to increasing levels of greenhouse gases. "Many of our models suggest cloud cover will go down in the future and that means that clouds will reflect less sunlight back to space, more will be absorbed at the surface and that will act as an amplifier to the warming we would get from carbon dioxide," Dr Robin Hogan, from the European Centre for Medium-Range Weather Forecasts, told BBC News.

The 2.3-tonne satellite was sent up from California on a SpaceX rocket. The project is led by the European Space Agency (ESA), which has described it as the organization's most complex Earth observation venture to date. Certainly, the technical challenge in getting the instruments to work as intended has been immense. It's taken fully 20 years to go from mission approval to launch. Earthcare will circle the Earth at a height of about 400km (250 miles). It's actually got four instruments in total that will work in unison to get at the information sought by climate scientists.

The simplest is an imager -- a camera that will take pictures of the scene passing below the spacecraft to give context to the measurements made by the other three instruments. Earthcare's European ultraviolet laser will see the thin, high clouds and the tops of clouds lower down. It will also detect the small particles and droplets (aerosols) in the atmosphere that influence the formation and behavior of clouds. The Japanese radar will look into the clouds, to determine how much water they are carrying and how that's precipitating as rain, hail and snow. And a radiometer will sense how much of the energy falling on to Earth from the Sun is being reflected or radiated back into space.

Sonos Enters the Headphones Market (wired.com) 11

After being rumored for years, Sonos has officially entered the headphones market with its new Ace headphones. "The Sonos Ace wireless over-ear active noise-canceling headphones are specified to go toe-to-toe with the established market leaders from the likes of Apple and Bose, and they're priced to match at $449," reports Wired. From the report: Visually, you get an elegant and notably slim pair of over-ear headphones in either a black or "soft" white matte finish. Thanks to a light 312-gram weight, and with some very well-judged clamping force and a clever hanger arrangement that conceals the hinged yoke inside the body of the ear cups, it means all-day comfort. The combination of memory foam, vegan leather, and stainless steel is equally beneficial where comfort and aesthetics are concerned. Branding is restricted to one ear cup, and it's laser-etched, so it manages to be understated while still catching the eye. Where the Apple AirPods Max shout "look at ME!," the Sonos Ace enunciate it quietly and precisely.

As far as performance is concerned, you get all the bells and whistles you'd expect. Wireless connectivity is via Bluetooth 5.4, and they have SBC and AAC codecs, allowing the Ace to be compatible with ALAC and Qualcomm Snapdragon Sound aptX Lossless. Sound is delivered by a pair of custom-designed 40-mm dynamic drivers. Sonos is characteristically coy about frequency response, but from my brief listen at a recent press event in London, they were full-range enough for real bass. Ported acoustic architecture allows for optimum low-frequency extension. Spatial audio is available via those streaming services that support Dolby Atmos and/or Sony 360 Reality Audio, and Sonos' Intelligent Motion Processing with Dolby Head Tracking dynamically follows your head movement to provide an even greater sensation of immersion and envelopment.

There are other cool features that most other headphones can't offer, by virtue of Sonos' ubiquity in many homes. At launch, the Ace will interact seamlessly with the Sonos Arc Dolby Atmos soundbar to swap TV sound between bar and phones at the touch of a button. Sonos suggests that compatibility with its other soundbars (Beam, Beam Gen 2, and Ray) is coming soon, along with a new TrueCinema technology that will map your listening space to reproduce your room's characteristics in the sound of the Ace.

Is America's Defense Department 'Rushing to Expand' Its Space War Capabilities? (japantimes.co.jp) 46

America's Defense Department "is rushing to expand its capacity to wage war in space," reports the New York Times, "convinced that rapid advances by China and Russia in space-based operations pose a growing threat to U.S. troops and other military assets on the ground and U.S. satellites in orbit." [T]he Defense Department is looking to acquire a new generation of ground- and space-based tools that will allow it to defend its satellite network from attack and, if necessary, to disrupt or disable enemy spacecraft in orbit, Pentagon officials have said in a series of interviews, speeches and recent statements... [T]he move to enhance warfighting capacity in space is driven mostly by China's expanding fleet of military tools in space... [U.S. officials are] moving ahead with an effort they are calling "responsible counterspace campaigning," an intentionally ambiguous term that avoids directly confirming that the United States intends to put its own weapons in space. But it also is meant to reflect this commitment by the United States to pursue its interest in space without creating massive debris fields that would result if an explosive device or missile were used to blow up an enemy satellite. That is what happened in 2007, when China used a missile to blow up a satellite in orbit. The United States, China, India and Russia all have tested such missiles. But the United States vowed in 2022 not to do any such antisatellite tests again.

The United States has also long had ground-based systems that allow it to jam radio signals, disrupting the ability of an enemy to communicate with its satellites, and is taking steps to modernize these systems. But under its new approach, the Pentagon is moving to take on an even more ambitious task: broadly suppress enemy threats in orbit in a fashion similar to what the Navy does in the oceans and the Air Force in the skies.

The article notes a recent report drafted by a former Space Force colonel cited three ways to disable enemy satellite networks: cyberattacks, ground or space-based lasers, and high-powered microwaves. "John Shaw, a recently retired Space Force lieutenant general who helped run the Space Command, agreed that directed-energy devices based on the ground or in space would probably be a part of any future system. 'It does minimize debris; it works at the speed of light,' he said. 'Those are probably going to be the tools of choice to achieve our objective." The Pentagon is separately working to launch a new generation of military satellites that can maneuver, be refueled while in space or have robotic arms that could reach out and grab — and potentially disrupt — an enemy satellite. Another early focus is on protecting missile defense satellites. The Defense Department recently started to require that a new generation of these space-based monitoring systems have built-in tools to evade or respond to possible attack. "Resiliency feature to protect against directed energy attack mechanisms" is how one recent missile defense contract described it. Last month the Pentagon also awarded contracts to two companies — Rocket Lab and True Anomaly — to launch two spacecraft by late next year, one acting as a mock enemy and the other equipped with cameras, to pull up close and observe the threat. The intercept satellite will not have any weapons, but it has a cargo hold that could carry them.
The article notes that Space Force's chief of space operations has told Senate appropriators that about $2.4 billion of the $29.4 billion in Space Force's proposed 2025 budget was set aside for "space domain awareness." And it adds that the Pentagon "is working to coordinate its so-called counterspace efforts with major allies, including Britain, Canada and Australia, through a multinational operation called Operation Olympic Defender. France has been particularly aggressive, announcing its intent to build and launch by 2030 a satellite equipped with a high-powered laser." [W]hat is clear is that a certain threshold has now been passed: Space has effectively become part of the military fighting domain, current and former Pentagon officials said. "By no means do we want to see war extend into space," Lt. Gen. DeAnna Burt, deputy chief of space operations, said at a Mitchell Institute event this year. "But if it does, we have to be prepared to fight and win."
