The Wall Street Journal reports that a European initiative studying the feasibility data centers in space "has found that the project could be economically viable" — while reducing the data center's carbon footprint. And they add that according to coordinator Thales Alenia Space, the project "could also generate a return on investment of several billion euros between now and 2050." The study — dubbed Ascend, short for Advanced Space Cloud for European Net zero emission and Data sovereignty — was funded by the European Union and sought to compare the environmental impacts of space-based and Earth-based data centers, the company said. Moving forward, the company plans to consolidate and optimize its results. Space data centers would be powered by solar energy outside the Earth's atmosphere, aiming to contribute to the European Union's goal of achieving carbon neutrality by 2050, the project coordinator said... Space data centers wouldn't require water to cool them, the company said. The 16-month study came to a "very encouraging" conclusion, project manager Damien Dumestier told CNBC. With some caveats... The facilities that the study explored launching into space would orbit at an altitude of around 1,400 kilometers (869.9 miles) — about three times the altitude of the International Space Station. Dumestier explained that ASCEND would aim to deploy 13 space data center building blocks with a total capacity of 10 megawatts in 2036, in order to achieve the starting point for cloud service commercialization... The study found that, in order to significantly reduce CO2 emissions, a new type of launcher that is 10 times less emissive would need to be developed. ArianeGroup, one of the 12 companies participating in the study, is working to speed up the development of such reusable and eco-friendly launchers. The target is to have the first eco-launcher ready by 2035 and then to allow for 15 years of deployment in order to have the huge capacity required to make the project feasible, said Dumestier... Michael Winterson, managing director of the European Data Centre Association, acknowledges that a space data center would benefit from increased efficiency from solar power without the interruption of weather patterns — but the center would require significant amounts of rocket fuel to keep it in orbit. Winterson estimates that even a small 1 megawatt center in low earth orbit would need around 280,000 kilograms of rocket fuel per year at a cost of around $140 million in 2030 — a calculation based on a significant decrease in launch costs, which has yet to take place. "There will be specialist services that will be suited to this idea, but it will in no way be a market replacement," said Winterson. "Applications that might be well served would be very specific, such as military/surveillance, broadcasting, telecommunications and financial trading services. All other services would not competitively run from space," he added in emailed comments. [Merima Dzanic, head of strategy and operations at the Danish Data Center Industry Association] also signaled some skepticism around security risks, noting, "Space is being increasingly politicised and weaponized amongst the different countries. So obviously, there is a security implications on what type of data you send out there." Its not the only study looking at the potential of orbital data centers, notes CNBC. "Microsoft, which has previously trialed the use of a subsea data center that was positioned 117 feet deep on the seafloor, is collaborating with companies such as Loft Orbital to explore the challenges in executing AI and computing in space." The article also points out that the total global electricity consumption from data centers could exceed 1,000 terawatt-hours in 2026. "That's roughly equivalent to the electricity consumption of Japan, according to the International Energy Agency."

Founded in 1846, the not-for-profit Associated Press distributes its news stories to other news outlets. But are free online sites putting those outlets at risk? This week the Associated Press wrote that a "crisis" in local and state news reporting "shows little signs of abating" — and that it's now setting up "a sister organization that will seek to raise money" for those outlets. The organization, which will have a board of directors independent of the AP, will solicit philanthropic spending to boost this news coverage, both within the AP and through outside organizations, the news outlet said Tuesday. "We feel we have to lean in at this point, not pull back," said Daisy Veerasingham, the AP's president and CEO. "But the supporting mechanism — the local newspaper market that used to support this — can't afford to do that anymore." Veerasingham said she's been encouraged by preliminary talks with some funders who have expressed concern about the state of local journalism... The local news industry has collapsed over the past two decades, with the number of journalists working in newspapers dropping from 75,000 to 31,000 in 2022, according to Northwestern University. More than half of the nation's counties have no local news outlets or only one. The AP's CEO offered this succinct summary of their goal. "We want to add new products and services to help the industry."

"The outdoor-apparel brand Patagonia has given 90 U.S. employees a choice," reports Business Insider: "tell the company by Friday that you're willing to relocate or leave your job." [Alternate URL here.] The employees all work in customer services, known at Patagonia as the customer-experience, or CX, team, and have been allowed to work remotely to field calls and inquiries. These workers received a text and email Tuesday morning about an "important" meeting... Two company executives, Amy Velligan and Bruce Old, told staff in a 15-minute video meeting that the team would be moving to a new "hub" model. CX employees are now expected to live within 60 miles of one of seven "hubs" — Atlanta; Salt Lake City; Reno, Nevada; Dallas; Austin; Chicago; or Pittsburgh. Workers were offered $4,000 toward relocation costs and extra paid time off. Those willing to relocate were told to do so by September 30. If CX staff are not willing to live near a hub city, they must leave the company. They were given 72 hours, until Friday, to confirm their decision... Access to company laptops and phones was shut off later that day until employees either agreed to relocate or said they wanted the severance, one affected CX worker said... Both employees who spoke to Business Insider believed this was because Patagonia didn't want to handle the increased demands of employees in states with higher costs of living. "We've been asking for raises for a long time, and they keep telling us that your wage is based on a Reno cost of living and where you choose to live is on you." According to the article, "The company hopes to bring staff together at the hubs at least once every six weeks for in-person training, company gatherings, or 'Activism Hours'." A company spokesperson described the changes as "crucial for us to build a vibrant team culture," and said there were workers who had been complaining about feeling disconnected. Though there may be another motive: "The reality is that our CX team has been running at 200% to 300% overstaffed for much of this year," she added. "While we hoped to reach the needed staffing levels through attrition, those numbers were very low, and retention remained high." One affected worker told Business Insider that the company's proposal "was very factual. If you don't live in these seven metro areas, you either need to move there or give us your stuff and hit the brick. If we don't respond by Friday, they will assume that we have chosen the severance package and we'll start that process." One worker added that the severance package they received was generous...

Lego teamed up with the European Space Agency to make Lego pieces from actual meteorite dust, writes Engadget. "It's a proof of concept to show how astronauts could use moondust to build lunar structures." Consider the sheer amount of energy and money required to haul up building materials from Earth to the Moon. It would be a game changer to, instead, build everything from pre-existing lunar materials. There's a layer of rock and mineral deposits at the surface of the Moon, which is called lunar regolith... However, there isn't too much lunar regolith here on Earth for folks to experiment with. ESA scientists made their own regolith by grinding up a really old meteorite. [4.5 billion years, according to Lego's site, discovered in Africa in 2000.] The dust from this meteorite was turned into a mixture that was used to 3D print the Lego pieces. Voila. Moon bricks. They click together just like regular Lego bricks, though they only come in one color (space gray obviously.) "The result is amazing," says ESA Science Officer Aidan Cowley on the Lego site (though "the bricks may look a little rougher than usual. Importantly the clutch power still works, enabling us to play and test our designs.") "Nobody has built a structure on the Moon," Cowley said in an ESA statement. "So it was great to have the flexibility to try out all kinds of designs and building techniques with our space bricks." And the bricks will also be "helping to inspire the next generation of space engineers," according to the ESA's announcement — since they'll be on display in select Lego stores in the U.S., Canada, the U.K., Spain, France, Germany, the Netherlands, and Australia through September 20th.

In November of 2022, "More than 800 people were selected to participate in the Denver Basic Income Project," reports the Colorado Sun, "while they were living on the streets, in shelters, on friends' couches or in vehicles. One group received $1,000 a month, according to the article, while a second group received $6,500 in the first month, and then $500 for the next 11 months. (And a "control" group received $50 a month.) Amazingly, about 45% of participants in all three groups "were living in a house or apartment that they rented or owned by the study's 10-month check-in point, according to the research." The number of nights spent in shelters among participants in the first and second groups decreased by half. And participants in those two groups reported an increase in full-time work, while the control group reported decreased full-time employment. The project also saved tax dollars, according to the report. Researchers tallied an estimated $589,214 in savings on public services, including ambulance rides, visits to hospital emergency departments, jail stays and shelter nights... The study, which began in November 2022 with payments to the first group of participants, has been extended for an additional eight months, until September, and organizers are attempting to raise money to extend it further.

Tom's Hardware reports that Japan's National Institute of Information and Communications Technology (working with the Aston Institute of Photonic Technologies and Nokia Bell) set a 402 terabits per second data transfer record — over commercially available optical fiber cables. The NICT and its partners were able to transmit signals through 1,505 channels over 50 km (about 31 miles) of optic fiber cable for this experiment. It used six types of amplifiers and an optical gain equalizer that taps into the unused 37 THz bandwidth to enable the 402 Tb/s transfer speed. One of the amplifiers this was demonstrated with is a thulium-based doped fiber amplifier, which uses C-band or C+L band systems. Additionally, semiconductor optical amplifiers and Raman amplifiers were used, which achieved 256 Tb/s data rate through almost 20 THz. Other amplifiers were also used for this exercise which provided a cumulative bandwidth of 25 THz for up to 119 Tb/s data rate. As a result, its maximum achievable result surpassed the previous data rate capacity by over 25 percent and increased transmission bandwidth by 35 percent. "This is achievable with currently available technology used by internet service providers..." the article points out. "With 'beyond 5G' potential speeds achievable through commercially available cables, it will likely further a new generation of internet services."

SK hynix early in Friday announced that the company has finished the development of it's PCB01 PCIe Gen5 SSD, the company's forthcoming high-end SSD for OEMs. Based on the company's new Alistar platform, the PCB01 is designed to deliver chart-topping performance for client machines. And, as a sign of the times, SK hynix is positioning the PCB01 for AI PCs, looking to synergize with the overall industry interest in anything and everything AI.

The bare, OEM-focused drives have previously been shown off by SK hynix, and make no attempt to hide what's under the hood. The PCB01 relies on SK hynix's Alistar controller, which features a PCIe Gen5 x4 host interface on the front end and eight NAND channels on the back end, placing it solidly in the realm of high-end SSDs. Paired with the Alistar controller is the company's latest 238-layer TLC NAND (H25T1TD48C & H25T2TD88C), which offers a maximum transfer speed of 2400 MT/second. Being that this is a high-end client SSD, there's also a DRAM chip on board, though the company isn't disclosing its capacity.

As with other high-end PCIe 5.0 client SSDs, SK hynix is planning on hitting peak read speeds of up to 14GB/second on the drive, while peak sequential write speeds should top 12GB/second (with pSLC caching, of course) – performance figures well within the realm of possibility for an 8 channel drive. As for random performance, at Computex the company was telling attendees that the drives should be able to sustain 4K random read and write rates of 2 million IOPS, which is very high as well. The SSDs are also said to consume up to 30% less power than 'predecessors,' according to SK hynix, though the company didn't elaborate on that figure. Typically in the storage industry, energy figures are based on iso-performance (rather than peak performance) – essentially measuring energy efficiency per bit rather than toal power consumption – and that is likely the case here as well.

At least initially, SK Hynix plans to release its PCB01 in three capacities – 512 GB, 1 TB, and 2 TB. The company has previously disclosed that their 238L TLC NAND has a capacity of 512Gbit, so these are typical capacity figures for single-sided drives. And while the focus of the company's press release this week was on OEM drives, this is the same controller and NAND that is also going into the company's previously-teased retail Platinum P51 SSD, so this week's reveal offers a bit more detail into what to expect from that drive family as well.

Specs aside, Ahn Hyun, the Head of the N-S Committee at SK hynix, said that multiple global CPU providers for on-device AI PCs are seeking collaboration for the compatibility validation process, which is underway, so expect PCB01 drives inside PCs in this back-to-school and holiday seasons.

"We will work towards enhancing our leadership as the global top AI memory provider also in the NAND solution space by successfully completing the customer validation and mass production of PCB01, which will be in the limelight," Ahn Hyun said.

"Stars very close to the center of our galaxy could be fueled by dark matter in perpetuity," writes Gizmodo, "according to a team of astronomers who recently studied the distant light sources." The group of stars, known as S-cluster stars, is just three light-years from the center of the Milky Way (for reference, we are about 26,000 light-years from the center of our galaxy, which hosts a supermassive black hole at its core). The stars are surprisingly young for their galactic neighborhood, yet they don't look like stars that simply migrated to this part of the Milky Way after forming in another location... As reported by Space.com, the research team posits that these weird stars may be accreting dark matter, which they then use as fuel to keep burning. Since models estimate there is plenty of dark matter near the galaxy's core, the stars are "forever young," as study lead author Isabelle John, an astrophysicist at the Kavli Institute for Particle Astrophysics and Cosmology told Space.com. Effectively, the stars have a long, long way to go before they start running low on fuel. The team's paper is currently hosted on the preprint server arXiv, meaning it has not yet gone through the process of peer review. Dark matter is only "seen" through its effects on other objects, the article points out — leading to lots of theories as to where it's actually located. "Earlier this year, a different team of researchers proposed that neutron stars — extremely dense stellar remnants — could actually be a source of dark matter. Last July, yet another team suggested that the Webb Telescope had detected stars that were powered by dark matter."
