"If, as astronomers believe, the death of large stars leave behind black holes, there should be hundreds of millions of them scattered throughout the Milky Way galaxy," notes an announcement from the University of California at Berkeley. "The problem is, isolated black holes are invisible.

"Now, a team led by University of California, Berkeley, astronomers has for the first time discovered what may be a free-floating black hole by observing the brightening of a more distant star as its light was distorted by the object's strong gravitational field — so-called gravitational microlensing." The team, led by graduate student Casey Lam and Jessica Lu, a UC Berkeley associate professor of astronomy, estimates that the mass of the invisible compact object is between 1.6 and 4.4 times that of the sun. Because astronomers think that the leftover remnant of a dead star must be heavier than 2.2 solar masses in order to collapse to a black hole, the UC Berkeley researchers caution that the object could be a neutron star instead of a black hole. Neutron stars are also dense, highly compact objects, but their gravity is balanced by internal neutron pressure, which prevents further collapse to a black hole.

Whether a black hole or a neutron star, the object is the first dark stellar remnant — a stellar "ghost" — discovered wandering through the galaxy unpaired with another star.

"This is the first free-floating black hole or neutron star discovered with gravitational microlensing," Lu said. "With microlensing, we're able to probe these lonely, compact objects and weigh them. I think we have opened a new window onto these dark objects, which can't be seen any other way...." The analysis by Lam, Lu and their international team has been accepted for publication in The Astrophysical Journal Letters. The analysis includes four other microlensing events that the team concluded were not caused by a black hole, though two were likely caused by a white dwarf or a neutron star.

The team also concluded that the likely population of black holes in the galaxy is 200 million — about what most theorists predicted.

Notably, a competing team from the Space Telescope Science Institute (STScI) in Baltimore analyzed the same microlensing event and claims that the mass of the compact object is closer to 7.1 solar masses and indisputably a black hole. A paper describing the analysis by the STScI team, led by Kailash Sahu, has been accepted for publication in The Astrophysical Journal....

The astrometric data came from NASA's Hubble Space Telescope.... While surveys like these discover about 2,000 stars brightened by microlensing each year in the Milky Way galaxy, the addition of astrometric data is what allowed the two teams to determine the mass of the compact object and its distance from Earth.

In 2003, the Human Genome Project finished sequencing every bit of human DNA, remembers MIT News.

"Now, over two decades later, MIT Professor Jonathan Weissman and colleagues have gone beyond the sequence to present the first comprehensive functional map of genes that are expressed in human cells." The data from this project, published online June 9 in Cell, ties each gene to its job in the cell, and is the culmination of years of collaboration on the single-cell sequencing method Perturb-seq.

The data are available for other scientists to use. "It's a big resource in the way the human genome is a big resource, in that you can go in and do discovery-based research," says Weissman, who is also a member of the Whitehead Institute and an investigator with the Howard Hughes Medical Institute....

"I think this dataset is going to enable all sorts of analyses that we haven't even thought up yet by people who come from other parts of biology, and suddenly they just have this available to draw on," says former Weissman Lab postdoc Tom Norman, a co-senior author of the paper.
The announcement credits the single-sequencing tool Perturb-seq and CRISPR-Cas9 genome editing which introduced genetic changes into cells and then captured information about which RNAs expressed (uses single-cell RNA sequencing).

The researchers scaled the method to the entire genome using human blood cancer cell lines and noncancerous cells derived from the retina, ultimately using Perturb-seq across more than 2.5 million cells.

"Researchers at MIT have discovered an unfixable vulnerability in Apple Silicon that could allow attackers to bypass a chip's 'last line of defense'," writes the Apple Insider blog, "but most Mac users shouldn't be worried." More specifically, the team at MIT's Computer Science & Artificial Intelligence Laboratory found that Apple's implementation of pointer authentication in the M1 system-on-chip can be overcome with a specific hardware attack they've dubbed "PACMAN." Pointer authentication is a security mechanism in Apple Silicon that makes it more difficult for attackers to modify pointers in memory. By checking for unexpected changes in pointers, the mechanism can help defend a CPU if attackers gain memory access.... The flaw comes into play when an attacker successfully guesses the value of a pointer authentication code and disables it.

The researchers found that they could use a side-channel attack to brute-force the code. PACMAN echoes similar speculative execution attacks like Spectre and Meltdown, which also leveraged microarchitectural side channels. Because it's a flaw in the hardware, it can't be fixed with a software patch.

[A]ctually carrying out the PACMAN attack requires physical access to a device, meaning the average Mac user isn't going to be at risk of exploit. The flaw affects all kinds of ARM-based chips — not just Apple's. The vulnerability is more of a technological demonstration of a wider issue with pointer authentication in ARM chips, rather than an issue that could lead to your Mac getting hacked.
MIT has made more information available at the site PACMANattack.com — including answers to frequently asked questions. Q: Is PACMAN being used in the wild?
A: No.
Q: Does PACMAN have a logo?
A: Yeah!
The MIT team says their discovery represents "a new way of thinking about how threat models converge in the Spectre era." But even then, MIT's announcement warns the flaw "isn't a magic bypass for all security on the M1 chip." PACMAN can only take an existing bug that pointer authentication protects against, and unleash that bug's true potential for use in an attack by finding the correct PAC. There's no cause for immediate alarm, the scientists say, as PACMAN cannot compromise a system without an existing software bug....

The team showed that the PACMAN attack even works against the kernel, which has "massive implications for future security work on all ARM systems with pointer authentication enabled," says Ravichandran. "Future CPU designers should take care to consider this attack when building the secure systems of tomorrow. Developers should take care to not solely rely on pointer authentication to protect their software."
TechCrunch obtained a comment from Apple: Apple spokesperson Scott Radcliffe provided the following: "We want to thank the researchers for their collaboration as this proof of concept advances our understanding of these techniques. Based on our analysis as well as the details shared with us by the researchers, we have concluded this issue does not pose an immediate risk to our users and is insufficient to bypass operating system security protections on its own."

Browser maker Vivaldi's email client has finally hit version 1.0, seven years after it was first announced. From a report: Vivaldi Mail, which includes a calendar and feed reader as well as an email client, first arrived in technical preview in 2020. A slightly wobbly beta arrived last year alongside version 4 of the Chromium-based browser. After another year of polish and tidying of loose ends, the company has declared the client ready.

As before, the client is built into the browser, meaning it is unlikely to appeal to many beyond Vivaldi's existing user base. Enabling it is a simple matter of dropping into Settings pages and wading through until the option to enable Mail, Calendar, and Feeds can be selected. Vivaldi has a lot of settings -- delightfully customizable for some and downright baffling for others. That said, for users still pining for a good old-fashioned email client that doesn't require wading through a web page festooned with adverts, there's a lot to like. It supports multiple accounts, will sort messages and create folders automatically (locally, rather than on a mystery server in the cloud), and permits searching (with indexing performed offline). IMAP and POP3 are supported, making adding a provider relatively straightforward, and the company also claims that users can log into their Google accounts from Mail and Calendar.

Anyone who has more money than they know what to do with eventually tries to cure aging. Google founder Larry Page has tried it. Jeff Bezos has tried it. Tech billionaires Larry Ellison and Peter Thiel have tried it. Now the kingdom of Saudi Arabia, which has about as much money as all of them put together, is going to try it. From a report: The Saudi royal family has started a not-for-profit organization called the Hevolution Foundation that plans to spend up to $1 billion a year of its oil wealth supporting basic research on the biology of aging and finding ways to extend the number of years people live in good health, a concept known as "health span." The sum, if the Saudis can spend it, could make the Gulf state the largest single sponsor of researchers attempting to understand the underlying causes of aging -- and how it might be slowed down with drugs. The foundation hasn't yet made a formal announcement, but the scope of its effort has been outlined at scientific meetings and is the subject of excited chatter among aging researchers, who hope it will underwrite large human studies of potential anti-aging drugs.

The fund is managed by Mehmood Khan, a former Mayo Clinic endocrinologist and the onetime chief scientist at PespsiCo, who was recruited to the CEO job in 2020. "Our primary goal is to extend the period of healthy lifespan," Khan said in an interview. "There is not a bigger medical problem on the planet than this one." The idea, popular among some longevity scientists, is that if you can slow the body's aging process, you can delay the onset of multiple diseases and extend the healthy years people are able to enjoy as they grow older. Khan says the fund is going to give grants for basic scientific research on what causes aging, just as others have done, but it also plans to go a step further by supporting drug studies, including trials of "treatments that are patent expired or never got commercialized."

"Microsoft on Thursday announced a new strategy for dealing with organized labor..." reports the Washington Post (in a story republished on MSN.com): In a blog post shared with The Washington Post, Microsoft President Brad Smith wrote that the company will respect workers' rights to unionize and plans to work collaboratively with organized labor organizations to "make it simpler rather than more difficult" for employees to unionize if they so choose.

Microsoft is in the process of completing a $69 billion acquisition of Activision, a video game company where employees of a small subsidiary voted to unionize in March. That union, the Game Workers Alliance, is a division of the Communications Workers of America (CWA), which in a statement called Microsoft's announcement "encouraging and unique among the major tech companies." CWA Secretary-Treasurer Sara Steffens added that "to truly give workers a legally protected voice in decisions that affect them and their families, these principles must be put into action and incorporated into Microsoft's day-to-day operations and its expectations for its contractors...."

Rebecca Givan, a Rutgers University professor of labor relations, said Microsoft's announcement could mean the company is trying to smooth things over with employees interested in unionizing. "There's a lot of actual organizing or talk or desire in the video game sector, and that's a piece of what Microsoft does. That might be what they're trying to get out in front of," Givan said.
The article argues that Microsoft is "attempting to set itself apart from other Big Tech firms like Google and Amazon that have clashed publicly with employees seeking union representation." And it provides specific examples where other big tech companies have "gotten into trouble" with America's National Labor Relations Board:

• "The labor board has repeatedly found that Amazon wrongfully terminated or retaliated against workers who were involved with union organizing."

• "Google, too, has had to settle charges with workers who said the company fired them in response to union organizing."

• "Workers at Apple told The Post in April that they were targeted by management for supporting the union and threatened with the loss of certain benefits and opportunities for promotion."

The president of America's largest federation of union, the AFL-CIO, tells the Post in a statement that "Microsoft's collaborative approach to working with its employees who seek to organize is a best practice that we look forward to seeing implemented at Microsoft and other companies."

"A new study from Stanford and the University of British Columbia has bad news for the next generation of nuclear reactors," writes Slashdot reader SoftwareArtist

An announcement from Stanford University warns that "Small modular reactors, long touted as the future of nuclear energy, will actually generate more radioactive waste than conventional nuclear power plants," citing joint research with the University of British Columbia published in Proceedings of the National Academy of Sciences. "Our results show that most small modular reactor designs will actually increase the volume of nuclear waste in need of management and disposal, by factors of 2 to 30 for the reactors in our case study," said study lead author Lindsay Krall, a former MacArthur Postdoctoral Fellow at Stanford University's Center for International Security and Cooperation (CISAC). "These findings stand in sharp contrast to the cost and waste reduction benefits that advocates have claimed for advanced nuclear technologies...."

Energy is produced in a nuclear reactor when a neutron splits a uranium atom in the reactor core, generating additional neutrons that go on to split other uranium atoms, creating a chain reaction. But some neutrons escape from the core — a problem called neutron leakage — and strike surrounding structural materials, such as steel and concrete. These materials become radioactive when "activated" by neutrons lost from the core. The new study found that, because of their smaller size, small modular reactors will experience more neutron leakage than conventional reactors. This increased leakage affects the amount and composition of their waste streams.

"The more neutrons that are leaked, the greater the amount of radioactivity created by the activation process of neutrons," Ewing said. "We found that small modular reactors will generate at least nine times more neutron-activated steel than conventional power plants. These radioactive materials have to be carefully managed prior to disposal, which will be expensive."
That's a problem because already, just in America, spent nuclear fuel is accumulating at a rate of about 2,000 metric tonnes per year, the announcement notes, and is "currently stored in pools or in dry casks at reactor sites."

But that's not the only issue: The study also found that the spent nuclear fuel from small modular reactors will be discharged in greater volumes per unit energy extracted and can be far more complex than the spent fuel discharged from existing power plants. "Some small modular reactor designs call for chemically exotic fuels and coolants that can produce difficult-to-manage wastes for disposal," said co-author Allison Macfarlane, professor and director of the School of Public Policy and Global Affairs at the University of British Columbia. "Those exotic fuels and coolants may require costly chemical treatment prior to disposal."

"The takeaway message for the industry and investors is that the back end of the fuel cycle may include hidden costs that must be addressed," Macfarlane said. "It's in the best interest of the reactor designer and the regulator to understand the waste implications of these reactors."

The study concludes that, overall, small modular designs are inferior to conventional reactors with respect to radioactive waste generation, management requirements, and disposal options. One problem is long-term radiation from spent nuclear fuel. The research team estimated that after 10,000 years, the radiotoxicity of plutonium in spent fuels discharged from the three study modules would be at least 50 percent higher than the plutonium in conventional spent fuel per unit energy extracted.

Because of this high level of radiotoxicity, geologic repositories for small modular reactor wastes should be carefully chosen through a thorough siting process, the authors said.

"We shouldn't be the ones doing this kind of study," said Ewing. "The vendors, those who are proposing and receiving federal support to develop advanced reactors, should be concerned about the waste and conducting research that can be reviewed in the open literature."

Last summer Chinese market analyst Ming-Chi Kuo reported the iPhone 13 would include satellite communication capability, remembers long-time tech pundit Robert Cringley, who adds that the prediction was denied by Apple. "This, in itself, was weird because Apple generally doesn't react to rumors. But beyond the mere reaction, the way Apple responded to Ming's prediction was especially odd." An unattributed leak from Cupertino said that the iPhone 13 definitely would not include satellite communication capability. And even if some iPhone could communicate with satellites, the leak continued, it wouldn't be offering satellite voice service (which Ming had mentioned), limiting iPhones to satellite text or iMessage.... This was making less and less sense, but it clearly meant there was something happening.

Then came the iPhone 13 launch and Ming was wrong for a change — no satellite communications. So the Cupertino rumor mill went about its business, Ming's satellite rumor apparently forgotten.

But not by me....
And this leads Cringley to another prediction of his own: I am convinced an announcement will be coming soon. Apple will shortly enter the satellite business by acquiring GlobalStar and its 24 satellites. They will use those 24, plus 24 more satellites that Apple has already commissioned, to offer satellite service for iMessage and Apple's Find My network just like they implied in their denial last year.

These apps are proxies for Apple entering — and then dominating — the Internet of Things (IoT) business. After all, iPhones will give them 1.6 billion points of presence for AirTag detection even on sailboats in the middle of the ocean — or on the South Pole.

IoT is already a big business that is going to get even bigger even faster because of Apple. Adding that satellite connection to iMessage and Find My offers the possibility of ubiquity for IoT, though only on Apple's network. Ubiquity (being able to track anything in near real time anywhere on the planet) signals the maturity of IoT, turning it quickly into a $1 TRILLION business — in this case Apple's $1 TRILLION business....

While Apple's stated goals will be only iMessage and Find My, followed by IoT, in the longer run Cupertino plans to dis-intermediate the mobile carriers — becoming themselves a satellite-based global phone and data company. That will require shifting over additional Globalstar bandwidth plus launching another 300-600 satellites, so it is several years away but IS coming. Apple will compete not just with every other mobile carrier including Cupertino's own customers, they will also compete with satellite Internet providers like Starlink, OneWeb, and Amazon's Kuiper. Apple can compete with Starlink with so many fewer satellites because GlobalStar has vastly more licensed spectrum than does SpaceX, which has to reuse the same spectrum over and over again with thousands of satellites.

NASA said this week that it plans to purchase five additional Crew Dragon missions from SpaceX to carry astronauts to the International Space Station. Ars Technica reports: Although the space agency's news release does not specifically say so, these may be the final flights NASA needs to keep the space station fully occupied into the year 2030. As of now, there is no signed international agreement to keep the station flying until then, but this new procurement sends a strong signal that the space agency expects the orbital outpost to keep flying that long.

The announcement also suggests that SpaceX will fly more than twice as many crews to the space station than the other partner in NASA's commercial crew program, Boeing. Under the new agreement, SpaceX would fly 14 crewed missions to the station on Crew Dragon, and Boeing would fly six during the lifetime of the station.

The New York state legislature has passed the United States' first "right to repair" bill covering electronics. The Verge reports: Called the Fair Repair Act, the measure would require all manufacturers who sell "digital electronic products" within state borders to make tools, parts, and instructions for repair available to both consumers and independent shops. Having passed the legislature, it is awaiting signature by Governor Kathy Hochul, who is expected to support the measure. The measure will take effect one year after it passes into law.

Self-repair groups like iFixit have applauded the ruling, calling it "one giant leap for repairkind" in a blog post following the announcement. "The passage of this bill means that repairs should become less expensive and more comprehensive: people who want to fix their own stuff can," the post reads. "Where before, manufacturers could push consumers to use manufacturer-authorized shops, now they'll have to compete."

An anonymous reader shares a report: Last month, the open source community was abuzz with excitement following a shocking announcement from System76 that HP was planning to release a laptop running the Pop!_OS operating system. This was significant for several reasons, but most importantly, it was a huge win for Linux users as yet another hardware option was becoming available. Best of all, HP employees have been trained by System76 to offer high-quality customer support. If you aren't aware, System76 support is legendary.

At the time of the announcement, details about the hardware were a bit scarce, but I am happy to report we now have full system specifications for the 14-inch HP Dev One laptop. Most interestingly, there is only one configuration to be had. The developer-focused computer is powered by an octa-core AMD Ryzen 7 PRO 5850U APU which features integrated Radeon graphics. The notebook comes with 16GB RAM and 1TB of NVMe storage, both of which can be user-upgraded later if you choose. The laptop is priced at $1,099.

Itochu, Mitsubishi and other companies are investing in Evering (Warning: source paywalled; alternative source), a chip-embedded smart ring that can act as a wallet and a key [...]. Bloomberg reports: Evering is backed by MTG, a listed Japanese health and beauty company. MTG struck a contract with Visa last year and began selling rings in Japan, which cost about 20,000 yen ($158) apiece, including tax. As retailers around the world seek ways to make it easier for consumers to shop seamlessly without touching anything, Evering and MTG are betting that their smart ring will resonate with early adopters. Made out of zirconia, the finger-worn gadget lets people do things such as lock and unlock doors, as well as pay for drinks in stores. More than 10 investors are considering investing a total of around 1 billion yen in Evering, which may eventually seek a public listing [...]. Potential backers include Daiwa House Industry and Toppan, with an announcement due soon.

It's been a bumpy ride for Netflix recently, and the announcement that it will be charging for password sharing hasn't gone as smoothly as it might have hoped, a new report claims. TechCrunch: Subscribers in Peru who were opted in to new password-sharing restrictions have reported confusion over Netflix's loose definition of "household" and noted the lack of clarity around the differing charges imposed on consumers. Global tech news site Rest of World informally surveyed more than a dozen Netflix users in Peru, after Netflix's March announcement that it would be asking customers in the country -- as well as in Chile and Costa Rica -- to pay extra when sharing their account passwords outside their homes. Central and South America represent Netflix's lowest revenue per user, which helps to explain the markets' selection.

The majority of those surveyed by Rest of World in Peru said that they have still not received uniform messaging around the new charges, even though it's been over two months after the policy was first announced. Some subscribers experienced the price increase and then canceled their Netflix accounts as a result. But others who ignored the message about the new policy were able to share their accounts across households without an extra charge, they claimed.

Microsoft looks set to announce an updated version of its compact Surface Laptop Go, if an early retailer listing from Korea is to be believed. From a report: The biggest change with the Surface Laptop Go 2 appears to be its newer 11th-gen Intel CPU (an i5-1135G7), which replaces the 10th-gen model found in the original 2020 laptop. The Go 2 will ship with Windows 11 this time around, and a Google Translate of the retailer page says its webcam will have "improved HD camera performance." Preorders are set to open on June 2nd, so an official announcement might not be far away. WinFuture previously reported that the laptop could have a starting price of $650. Otherwise, the new laptop appears to be very similar to its predecessor. It still has a 12.4-inch display with a 3:2 aspect ratio, the same selection of ports (USB-A, USB-C, a 3.5mm headphone jack, and a port for Microsoft's proprietary charger), and a fingerprint sensor that's still built into the power button on select models. There's no sign of a backlit keyboard, which was an unfortunate omission on the first Laptop Go.

An anonymous reader shares an excerpt from an opinion piece, written by Macworld's Michael Simon: Apple killed its Touch Bar on the 14-inch and 16-inch MacBook Pro last year, but PC makers seem determined to prove the company wrong. First Dell introduced the XPS 13 Plus which sports a "new capacitive touch experience that allows you to switch between media and function keys easily." The laptop is available for purchase but back-ordered for weeks, and there haven't been any reviews so we don't know for sure how it will be received, but Dell's touch bar concept seems even less useful than Apple's: the buttons are static, they merely float above the actual keyboard, and they don't appear to add any functionality. Then Dell added a touch bar to the trackpad on the Latitude 9330. [...]

Now there's a new PC touch bar, this time on the Voyager a1600, Corsair's first-ever gaming laptop. Corsair hasn't named or even officially announced the new feature -- it only appeared as a sneak peek -- but the company told The Verge that the strip features "10 easy-access customizable S-key shortcut buttons." [...] Corsair's Touch Bar doesn't replace the row of function keys but it is in an odd location -- on the hinge below the display. Even in pictures, it looks incredibly uncomfortable to reach. According to renders, you can still access the Touch Bar when the laptop is closed, which seems like an accident waiting to happen (not to mention a battery drain).

But the biggest question I have is: why? No one shed a tear for the Touch Bar when it was killed. While it has its merits, it was never a proper pro-level feature and the implementation didn't evolve past the original idea. It was too skinny, lacked tactile feedback, required constant scrolling, and didn't actually save time. It looked nice, but even Apple didn't seem to know what to do with it. The MacBook Pro Touch Bar was one of Apple's most polarizing features and it never really caught on with developers. Maybe a niche use like gaming or video conferencing will have better results, but ultimately the Touch Bar, Apple's or otherwise, is a failed concept that should stay in the past.

Inside of hard disk drives are platters which hold all your data; these are all manufactured by one company in Japan called Showa Denko which has announced it expects to "realize near-line HDD having storage capacity of more than 30TB" by the end of 2023. From a report: Deciphering that statement, we'd assume it will provide platters with a storage capacity of more than 3TB, sometime in 2023, to partners such as Toshiba, Seagate and Western Digital, who will then produce the hard disk drives, targeting hyperscalers and data centers operators. We'd expect some of them to end up in NAS and 3.5-inch external hard drives, but that won't be the main target markets, as performance is likely to be optimized for nearline usage.

Showa Denko has now started shipment of the platters that will go into new 26TB Ultrastar DC HC670 UltraSMR hard disk drives announced by Western Digital only a few days ago. A 2.6TB platter -- which uses energy-assisted magnetic recording and shingled magnetic recording -- also marks an important milestone as it hits the symbolic 1TB/in^2 density. Showa Denko's announcement comes as a surprise as Toshiba recently suggested 30TB drives (rather than higher capacities) would not come until 2024. A 30TB model would comprise of 11 platters with 2.73TB capacities each, a slight improvement on the 2.6TB capacity that are on the way. Given the fact that 26TB HDDs have now been announced in the first half of 2022, there's a remote chance that we could see 30TB drives before the end of the year or (as the saying goes), depending on market conditions.

Broadcom has announced it is acquiring VMware in a massive $61 billion deal. From a report: The deal is a combination of cash and stock, with Broadcom assuming $8 billion in VMware debt. With VMware, Broadcom gets more than the core virtualization, which the company was built on. It also gets other pieces it acquired along the way to diversify, like Heptio for containerization, and Pivotal, which helps provide support services for companies transitioning to modern technology. At the same time it bought Pivotal, it also acquired security company Carbon Black. That touches upon a lot of technology, but it begs the question, where does it all fit with Broadcom (which has spent a fair amount of money in recent years buying up a couple of key software pieces prior to today's announcement)?

Meta's ad transparency tools will soon reveal another treasure trove of data: advertiser targeting choices for political, election-related, and social issue spots. The Register reports: Meta said it plans to add the targeting data into its Facebook Open Research and Transparency (FORT) environment for academic researchers at the end of May. The move comes a day after Meta's reputation as a bad data custodian resurfaced with news of a lawsuit filed in Washington DC against CEO Mark Zuckerberg. Yesterday's filing alleges Zuckerberg built a company culture of mishandling data, leading directly to the Cambridge Analytica scandal. The suit seeks to hold Zuckerberg responsible for the incident, which saw millions of users' data harvested and used to influence the 2020 US presidential election.

Jeff King, Meta's VP of business integrity, said that FORT would allow researchers to look at detailed targeting information for social issue, electoral and political ads. "This data will be provided for each individual ad and will include information like the interest categories chosen by advertisers," King said. Prior to this announcement, data for social, electoral, and political ads in the run-up to the 2020 election was available as part of a pilot program. This new release will expand the pilot and add data from all ads in those categories run globally since 2020, King said.

The non-academic public has to wait until July to get their hands on that data in Facebook's Ad Library, and when released it will be in a summarized form. Included in the update will be data on total number of social, electoral, and political ads ran on a page using particular targeting data, percentage spent on the different issues, and whether the page uses a custom or lookalike audience. King said that Meta hopes the release will "help people better understand the practices used to reach potential voters on our technologies," and emphasized yet again that Meta is "committed to providing meaningful transparency, while also protecting people's privacy."

"Made In Space, Redwire, and Bigelow, move over," writes long-time Slashdot reader Dr. Crash. "There's yet another 3D printing in space group — and it's not a startup." Mitsubishi Electric just went public with a UV-sensitive resin specially made to print in zero-G and in a hard vacuum — as in outside the airlock.

The polymer is tuned to harden with solar ultraviolet light, so no UV lasers needed (saving power and launch weight).

Their first goal? Printing cubesat parabolic dishes in orbit, so a 300mm cubesat could have what looks like a one-meter dish antenna — or anything else that can be freeform-printed.
This "photopolymerization" technology "specifically addresses the challenge of equipping small, inexpensive spacecraft buses with large structures, such as high-gain antenna reflectors," according to Mitsubishi's announcement — arguing that it also ultimately "enables on-orbit fabrication of structures that greatly exceed the dimensions of launch vehicle fairings."

"The developer of the open source email client FairEmail pulled all of his applications from Google Play and announced that he would stop development," reports gHacks. The announcement comes shortly after the developer received an email from Google stating that they believed the app was spyware. From the report: FairEmail was a popular email client for Google's Android operating system that was free to use. It was privacy-friendly, had no limitations in regards to email accounts that users could set up in the app, supported unified inbox, conversation threading, two-way synchronizing, support for OpenPGP, and a lot more. Marcel Bokhorst, the developer of the application, announced major changes to the project yesterday on XDA Developers.

Earlier that week, Bokhorst received a policy violation email from Google stating that Google believed that the FairEmail application was spyware. The full statement has not been published, but Bokhorst believes that Google might have misinterpreted the use of favicons in the app. He resubmitted a new version of the application that had the use of favicons removed. The appeal he received as a response "resulted in a standard answer". While the content of the answer is unclear, it appears to have been a generic answer that Google Play Store developers have been frustrated with for a long time. Bokhorst decided to pull the application and all of his other applications from the Google Play Store. The apps won't be maintained and supported anymore according to the info.

Other factors played a role in Bokhorst's decision, including the discrepancy between answering thousands of support questions per month and the application's revenue, and the inability to do something against unfair reviews in the Google Play Store. He considered keeping the applications on GitHub, but this would result in an 98% loss of audience. Google also recently forced Total Commander's developer to remove the ability to install APKs from the File Manager.

If you're looking for an alternative email client, gHacks recommends the open-source app K-9 Mail.
