AMD has surpassed Intel in datacenter processor sales for the first time in history, marking a dramatic shift in the server chip market. AMD's datacenter revenue hit $3.549 billion in Q3, edging out Intel's $3.3 billion, according to SemiAnalysis.

The milestone ends Intel's decades-long dominance in server processors, where it held over 90% market share until recent years. AMD's EPYC processors now power many high-end servers, commanding premium prices despite selling at lower costs than comparable Intel chips.

Astronomers have discovered a supermassive black hole in the early Universe devouring matter at over 40 times the Eddington limit. ScienceAlert reports: Led by astronomer Hyewon Suh of Gemini Observatory and NSF's NOIRLab, a team of researchers used JWST to take follow-up observations of a smattering of galaxies identified by the Chandra X-ray Observatory that were bright in X-rays but dim in other wavelengths. When they got to LID-568, they were having trouble identifying its distance across space-time. The galaxy was very faint and very hard to see; but, using the integral field spectrograph on JWST's NIRSpec instrument, the team homed in on the galaxy's exact position. LID-568's far-off location is surprising. Although the object is faint from our position in the Universe, its distance means it must be incredibly intrinsically bright. Detailed observations revealed powerful outflows from the supermassive black hole, a signature of accretion as some of the material is being diverted and blasted into space.

A painstaking analysis of the data revealed that the supermassive black hole is a relatively small one, as supermassive black holes go; just 7.2 million times the mass of the Sun. And the amount of light being produced by the material around the disk was much, much higher than a black hole of this mass should be capable of producing. It suggests an accretion rate some 40 times higher than the Eddington limit. At this rate, the period of super-Eddington accretion should be extremely brief, which means Suh and her team were extremely lucky to catch it in action. And we expect that LID-568 will become a popular observation target for black hole scientists, allowing us a rare glimpse into super-Eddington processes. The research has been published in Nature Astronomy.

Five years ago remote workers were offered $10,0000 to move to Tulsa, Oklahoma for at least a year. Since then roughly 3,300 have accepted the offer, according to the New York TImes. [Alternate URL here.] But more importantly, now researchers are looking at the results: Their research, released this month, surveyed 1,248 people — including 411 who had participated in Tulsa Remote and others who were accepted but didn't move or weren't accepted but had applied to the program — and found that remote workers who moved to Tulsa saved an average of $25,000 more on annual housing costs than the group that was chosen but didn't move... Nearly three-quarters of participants who have completed the program are still living in Tulsa. The program brings them together for farm-to-table dinners, movie nights and local celebrity lectures to help build community, given that none have offices to commute to.
The article says every year the remote workers contribute $14.9 million in state income taxes and $5.8 million in sales taxes (more than offsetting the $33 million spent over the last five years). And additional benefits could be even greater. "We know that for every dollar we've spent on the incentive, there's been about a $13 return on that investment to the city," the program's managing director told Fortune — pointing out that the remote workers have an average salary of $100,000. (500 of the 3,300 even bought homes...)

The Tulsa-based George Kaiser Family Foundation — which provides the $10,000 awards — told the New York Times it will continue funding the program "so long as it demonstrates to be a community-enhancing opportunity." And with so much of the population now able to work remotely, the lead author on the latest study adds that "Every heartland mayor should pay attention to this..."

Long-time Slashdot reader schwit1 shared this report from the blog Interesting Engineering: A team of students made history this month by performing Europe's first rocket hop test.

Those who have followed SpaceX's trajectory will know hop tests are a vital stepping stone for a reusable rocket program, as they allow engineers to test their rocket's landing capabilities.

Impressively, no private company or space agency in Europe had ever performed a rocket hop test before. Essentially, a group of students performed one of the most important rocket tests in the history of European rocketry.

However, the remarkable nature of this story doesn't end there. Amazingly, the whole thing was almost derailed by a piece of cheese. A slice of Gruyère the team strapped to their rocket's landing legs almost caused the rocket to spin out of control.

Thankfully, disaster was averted, and the historic hopper didn't end up as rocket de-Brie.

Somewhere off in interstellar space, 15.4 billion miles away from Earth, NASA's 47-year-old Voyager "recently went quiet," reports Mashable.

The probe "shut off its main radio transmitter for communicating with mission control..." Voyager's problem began on October 16, when flight controllers sent the robotic explorer a somewhat routine command to turn on a heater. Two days later, when NASA expected to receive a response from the spacecraft, the team learned something tripped Voyager's fault protection system, which turned off its X-band transmitter. By October 19, communication had altogether stopped.

The flight team was not optimistic. However, Voyager 1 was equipped with a backup that relies on a different, albeit significantly fainter, frequency. No one knew if the second radio transmitter could still work, given the aging spacecraft's extreme distance.

Days later, engineers with the Deep Space Network, a system of three enormous radio dish arrays on Earth, found the signal whispering back over the S-band transmitter. The device hadn't been used since 1981, according to NASA.

"The team is now working to gather information that will help them figure out what happened and return Voyager 1 to normal operations," NASA said in a recent mission update.
It's been more than 12 years since Voyager entered interstellar space, the article points out. And interstellar space "is a high-radiation environment that nothing human-made has ever flown in before.

"That means the only thing the teams running the old probes can count on are surprises."

"One technology critical to fighting climate change is lagging," reports the Washington Post, "thanks to a combination of high interest rates, rising costs, misinformation and the cycle of home construction. Adoption of heat pumps, one of the primary ways to cut emissions from buildings, has slowed in the United States and stalled in Europe, endangering the switch to clean energy.

"Heat pump investment in the United States has dropped by 4 percent in the past two years, even as sales of EVs have almost doubled, according to data from MIT and the Rhodium Group. In 13 European countries, heat pump sales dropped nearly in half in the first half of 2024, putting the European Union off-track for its climate goals." "Many many markets are falling," said Paul Kenny, the director general of the European Heat Pump Association. "It takes time to change people's minds about a heating system." Heat pumps — essentially air conditioners that can also work in reverse, heating a space as well as cooling it — are crucial to making buildings more climate-friendly. Around 60 percent of American homes are still heated with furnaces running on oil, natural gas, or even propane; to cut emissions from homes, all American houses and apartments will need to be powered by electricity...

In the United States, experts point to lags in construction, high interest rates, and general belt-tightening from inflation... [Cora Wyent, director of research for the electrification advocacy group Rewiring America] added, heat pumps are still growing as a share of overall heating systems, gaining ground on gas furnaces. In 2023, heat pumps made up 55 percent of all heating systems sold, while gas furnaces made up just 45 percent. "Heat pumps are continuing to increase their total market share," she said.

Homeowners may also run into trouble when trying to find contractors to install heat pumps. Barton James, the president and CEO of the Air Conditioning Contractors of America, says many contractors don't have training on how to properly install heat pumps; if they install them incorrectly, the ensuing problems can sour consumers on the technology... In the United States, low gas prices also make the economics of heat pumps more challenging. Gas is around three times cheaper than electricity — while heat pumps make up most of that ground with efficiency, they aren't the most cost-effective option for every household.
The Post also spoke to the manager for the carbon-free buildings team at the clean energy think tank RMI. They pointed out that heating systems need to be replaced roughly every 15 years — and the next cycle doesn't start until 2035.

The article concludes that "even with government policies and subsidies, many parts of the move to clean energy will require individual people to make changes to their lives. According to the International Energy Agency, the number of heat pumps will have to triple by 2030 to stay on track with climate goals. The only way to do that, experts say, is if incentives, personal beliefs, and technology all align."

This week's Ubuntu Summit 2024 was attended by Lproven (Slashdot reader #6,030). He's also a FOSS correspondent for the Register, where he's filed this report: One of the first full-length sessions was presented by David Morin, executive director of the Academy Software Foundation, introducing his organization in a talk about Open Source Software for Motion Pictures. Morin linked to the Visual Effects Society's VFX/Animation Studio Workstation Linux Report, highlighting the market share pie-chart, showing Rocky Linux 9 with at some 58 percent and the RHELatives in general at 90 percent of the market. Ubuntu 22 and 24 — the report's nomenclature, not this vulture's — got just 10.5 percent. We certainly didn't expect to see that at an Ubuntu event, with the latest two versions of Rocky Linux taking 80 percent of the studio workstation market...

What also struck us over the next three quarters of an hour is that Linux and open source in general seem to be huge components of the movie special effects industry — to an extent that we had not previously realized.
There's a "sizzle reel" showing examples of how major motion pictures used OpenColorIO, an open-source production tool for syncing color representations originally developed by Sony Pictures Imageworks. That tool is hosted by a collaboration between the Linux Foundation with the Science and Technology Council of the Academy of Motion Picture Arts and Sciences (the "Academy" of the Academy Awards). The collaboration — which goes by the name of the Academy Software Foundation — hosts 14 different projects The ASWF hasn't been around all that long — it was only founded in 2018. Despite the impact of the COVID pandemic, by 2022 it had achieved enough to fill a 45-page history called Open Source in Entertainment [PDF]. Morin told the crowd that it runs events, provides project marketing and infrastructure, as well as funding, training and education, and legal assistance. It tries to facilitate industry standards and does open source evangelism in the industry. An impressive list of members — with 17 Premier companies, 16 General ones, and another half a dozen Associate members — shows where some of the money comes from. It's a big list of big names. [Adobe, AMD, AWS, Autodesk...]
The presentation started with OpenVBD, a C++ library developed and donated by Dreamworks for working with three-dimensional voxel-based shapes. (In 2020 they created this sizzle reel, but this year they've unveiled a theme song.) Also featured was OpenEXR, originally developed at Industrial Light and Magic and sourced in 1999. (The article calls it "a specification and reference implementation of the EXR file format — a losslessly compressed image storage format for moving images at the highest possible dynamic range.")

"For an organization that is not one of the better-known ones in the FOSS space, we came away with the impression that the ASWF is busy," the article concludes. (Besides running Open Source Days and ASWF Dev Days, it also hosts several working groups like the Language Interop Project works on Rust bindings and the Continuous Integration Working Group on CI tools, There's generally very little of the old razzle-dazzle in the Linux world, but with the demise of SGI as the primary maker of graphics workstations — its brand now absorbed by Hewlett Packard Enterprise — the visual effects industry moved to Linux and it's doing amazing things with it. And Kubernetes wasn't even mentioned once.

The Washington Post reports that America's Consumer Financial Protection Bureau (or CFPB) "is considering legal action against Meta over allegations that it improperly used financial data obtained from third parties in its highly-lucrative advertising business..."

The article says a Meta securities filing Thursday revealed it had received a formal notification about the federal investigation last month. The filing said only that the inquiry relates to "advertising for financial products and services on our platform." A spokesperson for Meta declined to comment on the investigation. "We disagree with the claims," the company's filing said, "and believe an enforcement action is unwarranted...."

The CFPB's probe underscores its aggressive recent focus on Big Tech. In recent years, major companies including Apple, Amazon, Facebook and Google have launched a wave of new financial services, including credit cards and apps that help users send money to friends... Under its current director, Rohit Chopra, the CFPB has also sought to ensure that tech giants adhere to the same safeguards that have long applied to their brick-and-mortar banking predecessors. The bureau formalized its tech crackdown in 2021, when Chopra ordered companies including Facebook to turn over records related to their payment apps and other financial service offerings.

At the time, he expressed fear that these giants already possessed troves of customer data and could solidify their dominance if they gained greater insight into users' purchasing and spending habits. "This data can be monetized by companies that seek to profit from behavioral targeting, particularly around advertising and e-commerce," Chopra said in a statement announcing the review. "That many Big Tech companies aspire to grow in this space only heightens these concerns." Since then, the watchdog agency has proposed new rules that could treat Apple, Google and PayPal-owned Venmo more like banks, opening the door for federal regulators to inspect some of their operations in a bid to protect users' deposits.

The rules, which have not been finalized, have sparked fierce lobbying opposition from major tech companies.

An anonymous reader quotes a report from The Guardian: A new global inventory has catalogued air pollution from space activities from 2020 to 2022. The inventory includes time, position and pollution from 446 launchers as they ascended and the tracks of re-entries as objects are heated to extreme temperatures and break up or burn up in the upper atmosphere. It catalogues the pollution from 63,000 tons of rocket propellants used in 2022 and from 3,622 objects, including rocket parts and satellites, that re-entered the atmosphere between 2020 and 2023, amounting to about 12,000 tons. [...]

Types of launch pollutants depend on the propellent but can include particles of soot and aluminum oxides as well as nitrogen oxides, chlorine and water vapour and carbon dioxide. Extreme heat on re-entry causes atmospheric oxygen and nitrogen to combine to form more nitrogen oxides and also produces tiny metal-oxide particles as the objects break and burn up. Soot emitted high in the atmosphere can persist for several years, with a resulting climate warming impact that is up to 500 times greater than the same amount of soot from aviation or ground-level sources. Aluminum oxide particles, nitrogen oxides and chloride can consume the ozone in the stratosphere that protects us from the sun's ultraviolet radiation. These can remain in the atmosphere for decades. Dr Connor Barker, of the UCL team, said: "Many rocket manufacturers and space agencies keep this information tightly controlled. We had to be creative about the different sources we consulted, from launch live streams on YouTube to online databases maintained by space enthusiasts in their spare time."

A new study suggests Uranus' moon Miranda may harbor a vast subsurface ocean, challenging previous assumptions about its frozen state and positioning it as a potential ocean world alongside other icy moons. Phys.Org reports: Among the moons in the solar system, Miranda stands out. The few images Voyager 2 captured in 1986 show Miranda's southern hemisphere (the only part we've seen) is a Frankenstein-like hodgepodge of grooved terrain quartered off by rough scarps and cratered areas, like squares on a quilt. Most researchers suspect these bizarre structures are the result of tidal forces and heating within the moon. Caleb Strom, a graduate student at the University of North Dakota who worked with Nordheim and Alex Patthoff of the Planetary Science Institute in Arizona, revisited the Voyager 2 images. The team set out to explain Miranda's enigmatic geology by reverse engineering the surface features, working backward to uncover what the moon's interior structure must have been to shape the moon's geology in response to tidal forcing.

After first mapping the various surface features like cracks, ridges and Miranda's unique trapezoidal coronae, the team developed a computer model to test several possible structures of the moon's interior, matching the predicted stress patterns to the actual surface geology. The setup that produced the best match between predicted stress patterns and observed surface features required the existence of vast ocean beneath Miranda's icy surface some 100-500 million years ago. This subsurface ocean was at least 62 miles (100 kilometers) deep, according to the study, and hidden beneath an icy crust no more than 19 miles (30 kilometers) thick. Given Miranda has a radius of just 146 miles (235 kilometers), the ocean would have filled almost half of the moon's body. "That result was a big surprise to the team," Strom said.

Key to creating that ocean, the researchers believe, were tidal forces between Miranda and nearby moons. These regular gravitational tugs can be amplified by orbital resonances -- a configuration where each moon's period around a planet is an exact integer of the others' periods. Jupiter's moons Io and Europa, for example, have a 2:1 resonance: For every two orbits Io makes around Jupiter, Europa makes exactly one, leading to tidal forces that are known to sustain an ocean beneath Europa's surface. These orbital configurations and the resulting tidal forces deform the moons like rubber balls, leading to friction and heat that keeps interiors warm. This also creates stresses that crack the surface, creating a rich tapestry of geologic features. Numerical simulations have suggested that Miranda and its neighboring moons likely had such a resonance in the past, offering a potential mechanism that could have warmed Miranda's interior to produce and maintain a subsurface ocean.

At some point, the moons' orbital ballet desynchronized, slowing the heating process so that the moon's insides started to cool and solidify. But the team doesn't think Miranda's interior has fully frozen yet. If the ocean had completely frozen, Nordheim explained, it would have expanded and caused certain telltale cracks on the surface, which aren't there. This suggests that Miranda is still cooling -- and may have an ocean beneath its surface even now. Miranda's modern-day ocean is probably relatively thin, Strom noted. "But the suggestion of an ocean inside one of the most distant moons in the solar system is remarkable," he said. Miranda wasn't predicted to have an ocean. With its small size and old age, scientists thought it would likely be a frozen ball of ice. Any leftover heat from its formation was assumed to have dissipated long ago. But as Patthoff pointed out, predictions about ice moons can be wrong, as evidenced by Saturn's moon Enceladus. The study has been published in The Planetary Science Journal.

Dropbox is letting go 20% of its workforce as the cloud company undergoes what CEO Drew Houston calls a "transitional period." From a report: In a letter to staff, Houston said that the reduction in headcount would impact 528 people. The goal, he added, was to make cuts in areas where Dropbox has "over-invested" while designing a "flatter, more efficient" team structure.

"As CEO, I take full responsibility for this decision and the circumstances that led to it, and I'm truly sorry to those impacted by this change," he wrote. "This market is moving fast and investors are pouring hundreds of millions of dollars into this space. This both validates the opportunity we've been pursuing and underscores the need for even more urgency, even more aggressive investment, and decisive action." According to a filing with the SEC, Dropbox estimates it'll lay out total cash expenditures of $63 million to $68 million on the layoffs, primarily in the form of severance and benefits, and recognize $47 million to $52 million of incremental expense.

An anonymous reader quotes a report from the European Space Agency: White dots arranged in five clusters against a black background (PNG). This is the simulated extraterrestrial signal transmitted from Mars and deciphered by a father and a daughter on Earth after a year-long decoding effort. On June 7, 2024, media artist Daniela de Paulis received this simple, retro-looking image depicting five amino acids in her inbox. It was the solution to a cosmic puzzle beamed from ESA's ExoMars Trace Gas Orbiter (TGO) in May 2023, when the European spacecraft played alien as part of the multidisciplinary art project 'A Sign in Space.' After three radio astronomy observatories on Earth intercepted the signal, the challenge was first to extract the message from the raw data of the radio signal, and secondly to decode it. In just 10 days, a community of 5000 citizen scientists gathered online and managed to extract the signal. The second task took longer and required some visionary minds.

US citizens Ken and Keli Chaffin cracked the code following their intuition and running simulations for hours and days on end. The father and daughter team discovered that the message contained movement, suggesting some sort of cellular formation and life forms. Amino acids and proteins are the building blocks of life. Now that the cryptic signal has been deciphered, the quest for meaning begins. The interpretation of the message, like any art piece, remains open. Daniela crafted the message with a small group of astronomers and computer scientists, with support from ESA, the SETI Institute and the Green Bank Observatory. The artist and collaborators behind the project are now taking a step back and witnessing how citizen scientists are shaping the challenge on their own.

Federal Communications Commission Chair Jessica Rosenworcel outlined a vision for universal connectivity last week that merges satellite and ground-based networks. The FCC recently became the first regulator to establish a framework for supplemental coverage from space (SCS). "Satellites may be in our skies, but they are the anchor tenant in our communications future," said Rosenworcel, calling for seamless integration of fiber, cellular, wireless, and satellite infrastructure into a unified network. The vision comes as the FCC's Affordable Connectivity Program recently ended due to funding depletion.

NASA's economic impact report highlights that in fiscal year 2023, the agency's initiatives contributed $75.6 billion to the U.S. economy, created over 300,000 jobs, and drove advancements in areas like space exploration, climate research, and technology innovation. The agency's budget for that year was $25.4 billion. Space.com reports: The Moon to Mars program alone created $23.8 billion in economic output and 96,479 jobs, while investments in climate research and technology contributed $7.9 billion and 32,900 jobs. The report also drills down into impacts in each state, with 45 states seeing over $10 million in impact and eight states surpassing the $1 billion mark. [...]

NASA's missions supported 304,803 jobs across America, according to the report -- the third agency-wide study of its kind -- generating an estimated total of $9.5 billion in federal, state, and local taxes. Additionally, NASA's technological innovations and transfers in 2023 led to 40 new patent applications, 69 patents issued, and thousands of software usage agreements. A number of NASA technology spinoffs have become everyday household items. The full NASA economic impact report can be found here.

Ars Technica's Stephen Clark reports: For those who follow NASA's human spaceflight program, a burning question for the last year-and-a-half has been what caused the Orion spacecraft's heat shield to crack and chip away during atmospheric reentry on the unpiloted Artemis I test flight in late 2022. Multiple NASA officials said Monday they now know the answer, but they're not telling. Instead, agency officials want to wait until more reviews are done to determine what this means for Artemis II, the Orion spacecraft's first crew mission around the Moon, officially scheduled for launch in September 2025.

"We have gotten to a root cause," said Lakiesha Hawkins, assistant deputy associate administrator for NASA's Moon to Mars program office, in response to a question from Ars on Monday at the Wernher von Braun Space Exploration Symposium. "We are having conversations within the agency to make sure that we have a good understanding of not only what's going on with the heat shield, but also next steps and how that actually applies to the course that we take for Artemis II," she said. "And we'll be in a position to be able to share where we are with that hopefully before the end of the year."

While the space program is far down the list of most voters' priorities, this means a decision and announcement on what will happen with Artemis II won't come until the post-election lame duck period in the waning weeks of the Biden administration, and likely Bill Nelson's tenure as NASA administrator. This is several months later than NASA officials expected to make a decision. The question here is whether NASA managers decide it is safe enough to fly the Orion heat shield as-is on Artemis II, or if it is too risky with people onboard. Artemis II will be a 10-day mission taking its four-person crew on a path around the far side of the Moon, then back to Earth. This will be the first time people travel to such distances since the Apollo program ended more than 50 years ago.

An anonymous reader quotes a report from TechCrunch: Similar to how Mastodon offers an open source, distributed version of X, the fediverse is getting its own TikTok competitor. This week, an app called Loops began accepting signups on its new platform for sharing short, looping videos. Still in the early stages, Loops is not yet open sourced, nor has it completed its integration with ActivityPub, the protocol that powers Mastodon, Pixelfed, PeerTube, and other federated apps. However, both those efforts are in the works and when complete, will allow Loops to add another layer of social activity to the growing open social web known as the fediverse, which now has north of 11.6 million users and over 1 million monthly active users. (Mastodon accounts for roughly 65% of that activity.) Growth in this space has also encouraged other apps to adopt ActivityPub, like social magazine app Flipboard and Meta's Threads. The latter is not yet fully integrated but already has more than 200 million monthly active users.

Loops, meanwhile, was developed by Daniel Supernault, who also created the federated Instagram rival Pixelfed. In fact, Loops will run under the Pixelfed project, according to an FAQ on its website. [...] Aimed at users 13 and up, Loops will allow you to follow other users, as well as like, comment on, or share their videos. But as a part of the federated web -- the open social web running on ActivityPub -- remote users from other platforms like Mastodon and Pixelfed will also be able to follow users' Loops accounts and then view the videos in their home feed on those respective platforms. These remote followers will also be able to like, comment on, or share videos if their platform supports it. Videos published to the app will be held for moderation if the uploader has a low trust score, but trusted users will be able to skip the queue and publish immediately. The trust score is also used to hide problematic comments on posts and apply content warnings, Supernault notes. Other features, like profile sharing or the ability for Loops users to follow Mastodon and Pixelfed users in return, are still "to be announced," the site notes.

There's finally an "official" definition of open source AI. The Open Source Initiative (OSI), a long-running institution aiming to define and "steward" all things open source, today released version 1.0 of its Open Source AI Definition (OSAID). TechCrunch: The product of several years of collaboration with academia and industry, the OSAID is intended to offer a standard by which anyone can determine whether AI is open source -- or not. You might be wondering why consensus matters for a definition of open source AI. Well, a big motivation is getting policymakers and AI developers on the same page, said OSI EVP Stefano Maffulli.

"Regulators are already watching the space," Maffulli told TechCrunch, noting that bodies like the European Commission have sought to give special recognition to open source. "We did explicit outreach to a diverse set of stakeholders and communities -- not only the usual suspects in tech. We even tried to reach out to the organizations that most often talk to regulators in order to get their early feedback." [...] To be considered open source under the OSAID, an AI model has to provide enough information about its design so that a person could "substantially" recreate it. The model must also disclose any pertinent details about its training data, including the provenance, how the data was processed, and how it can be obtained or licensed.

When SpaceX developed reusable boosters for its Falcon rockets, it helped cut costs of launches.

Now the Wall Street Journal reports that last week's first-time catch of "its huge Starship booster" could "extend SpaceX's cost advantages, especially in launches to low-Earth orbit, where SpaceX and others operate satellites." A fully and rapidly reusable Starship would push down SpaceX's costs by limiting the need to crank out new hardware and cutting downtime between flights, space industry executives say. Bain, the consulting firm, has estimated that Starship would reduce the cost of getting each kilogram to low-Earth orbit by 50 to 80 times... SpaceX's rocket peers are moving toward reusability, but they are behind the progress Musk's company has made.

- The huge booster that will power New Glenn, the orbital rocket Jeff Bezos' Blue Origin is developing, is designed to be reusable. That rocket is slated to launch for the first time next month.

- ULA, the rocket operator owned by Boeing and Lockheed Martin, is looking to recover the two engines that help power the first part of its new rocket, Vulcan Centaur. The parent company for Arianespace, whose new vehicle is powered by an expendable booster, has also invested in a startup developing a reusable booster.

- Last year, Rocket Lab USA used an engine that had flown before on a flight of its Electron rocket, and is working on a new vehicle, called Neutron, with a booster it could use again.

- Jason Kim, chief executive of Firefly Aerospace, said the reusable vehicle the Texas-based company is developing with Northrop Grumman would give launch customers more flexibility and better pricing. "It really comes down to the affordability and the schedule," Kim said in a recent interview.
"We need reusability for rockets, just like we have reusability for cars, for airplanes, for bicycles, for horses," Musk said in a video SpaceX posted earlier this year...

Communications of the ACM checks in on the quest for room-temperature superconductivity. "Time and time again, physicists have announced breakthroughs that were later found to be irreproducible, in error, or even fraudulent."

But "The issue is once again simmering..." In January 2024, a group of researchers from Europe and South America announced they had achieved a milestone in room-temperature ambient-pressure superconductivity. Using Scotch-taped cleaved pyrolytic graphite with surface wrinkles, which formed line defects, they observed a room-temperature superconducting state. Their paper, published in the journal Advanced Quantum Technologies, has gained considerable attention in the scientific world... Although many in the scientific community remain incredulous, if valid, this development could help solve a key piece of the puzzle: how defects and wrinkles in a material such as scotch-taped cleaved pyrolytic graphite (HOPG) affect electrical properties and behavior within superconductive systems...

"We haven't reached a point where there is a clear path to room temperature superconductivity because researchers are either overly enthusiastic or deceptive," said Elie Track, chief technology officer at HYPRES, Inc., an Elmsford, NY, company that develops and commercializes superconductor integrated circuits (ICs) and systems. "People fail to check measurements and others can't reproduce their results. There is a lot of carelessness and sloppy science surrounding the space because people are so eager to achieve success." The team conducting research into scotch-taped cleaved pyrolytic graphite believe their discovery could tilt the search for practically useful room-temperature superconductivity in a favorable direction. They reported they were able to achieve one-dimensional superconductivity in pyrolytic graphite at temperatures as great as 300 degrees Kelvin (26.85 degrees Celsius), and at ambient pressure. Vinokur and physicist Maria Cristina Diamantini described the development as the first "unambiguous experimental evidence" for a global room temperature zero-resistance state. If true, the team's research could illuminate a path to new superconducting materials....

Others remain skeptical, however. For example Alan Kadin [a technical consultant in the field and a former professor of electrical engineering at the University of Rochester] pointed out that one of the key researchers for the project, Yakov Kopelevich, has been working in the field for two decades and, so far, "The results are not reproducible in other labs...Until someone else independently reproduces these results, I think we can safely ignore them," he argued...

Yet as scientists continue to bang away at the superconducting challenge — including the possibility of using generative AI to explore materials and techniques — optimism is growing that a major breakthrough could occur.

"Friction between bosses and their employees over the terms of their return shows no signs of abating," reports the Los Angeles Times. But there's one big loophole... About 80% of organizations have put in place return-to-office policies, but in a sign that many managers are reluctant to clamp down on the flexibility employees have become accustomed to, only 17% of those organizations actively enforce their policies, according to recent research by real estate brokerage CBRE. "Some organizations out there have 'mandated' something, but if most of your organization is not following that mandate, then there is not too much you can do to enforce it," said Julie Whelan, head of research into workplace trends for CBRE...

The tension "is due to the fact that we have changed since we all went to our separate corners and then came back" from pandemic-imposed office exile, said Elizabeth Brink, a workplace expert at architecture firm Gensler. "It's fair to say that we have different needs now." A disconnect persists between employer expectations for office attendance and employee behavior, CBRE found. Sixty percent of leaders surveyed said they want their employees in the office three or more days a week, while only 51% reported that employees work in the office at that frequency. Conversely, 37% of employees show up one or two days a week, yet only 17% of employers are satisfied with that attendance.
In the article, one worker complains about their employer's two-days-a-week of mandated in-office time. "I feel like I'm back in grade school and being forced to sit down and do my homework."
