Single Hubble Image Captured Supernova At Three Different Times (arstechnica.com) 3

John Timmer writes via Ars Technica: Over the last few decades, we've gotten much better at observing supernovae as they're happening. Orbiting telescopes can now pick up the high-energy photons emitted and figure out their source, allowing other telescopes to make rapid observations. And some automated survey telescopes have imaged the same parts of the sky night after night, allowing image analysis software to recognize new sources of light. But sometimes, luck still plays a role. So it is with a Hubble image from 2010, where the image happened to also capture a supernova. But, because of gravitational lensing, the single event showed up at three different locations within Hubble's field of view. Thanks to the quirks of how this lensing works, all three of the locations captured different times after the star's explosion, allowing researchers to piece together the time course following the supernova, even though it had been observed over a decade earlier. [...]

By checking that Hubble data against different classes of supernovae that we've imaged in the modern Universe, it was likely to be produced by the explosion of either a red or blue supergiant star. And the detailed properties of the event were a much better fit to a red supergiant, one that was roughly 500 times the size of the Sun at the time of its explosion. The intensity of the light at different wavelengths provides an indication of the explosion's temperature. And the earliest image indicates that it was roughly 100,000 Kelvin, which suggests we were looking at it just six hours after it exploded. The latest lensed image shows that the debris had already cooled to 10,000 K over the eight days between the two different images.

Obviously, there are more recent and closer supernovae that we can study in far more detail if we want to understand the processes that drive a massive star's explosion. If we're able to find more of these lensed supernovae in the distant past, however, we'll be able to infer things about the population of stars that were present much earlier in the Universe's history. At the moment, however, this is only the second one we've found. The authors of the paper describing it make an effort to draw some inferences, but it's clear those will have a higher uncertainty. So, in many ways, this doesn't help us make major advances in understanding the Universe. But as an example of the strange consequences of the forces that govern the Universe's behavior, it's a pretty impressive one.
The findings appear in the journal Nature.

Debris From Destroyed Space Shuttle Challenger Found On Ocean Floor 36 Years On (www.cbc.ca) 6

A large section of the destroyed space shuttle Challenger has been found buried in sand at the bottom of the Atlantic, more than three decades after the tragedy that killed a schoolteacher and six others. CBC.ca reports: NASA's Kennedy Space Center announced the discovery Thursday. "Of course, the emotions come back, right?" said Michael Ciannilli, a NASA manager who confirmed the remnant's authenticity. When he saw the underwater video footage, "My heart skipped a beat, I must say, and it brought me right back to 1986 ... and what we all went through as a nation." It's one of the biggest pieces of Challenger found in the decades since the accident, according to Ciannilli, and the first remnant to be discovered since two fragments from the left wing washed ashore in 1996.

Divers for a History Channel TV documentary first spotted the piece in March while looking for wreckage of a Second World War plane. NASA verified through video a few months ago that the piece was part of the shuttle that broke apart shortly after liftoff on Jan. 28, 1986. All seven on board were killed, including the first schoolteacher bound for space, Christa McAuliffe. The underwater video provided "pretty clear and convincing evidence," said Ciannilli. The piece is more than 4.5 metres by 4.5 metres, and likely bigger because part of it is covered with sand. Because there are square thermal tiles on the piece, it's believed to be from the shuttle's belly, Ciannilli said.

The fragment remains on the ocean floor just off the Florida coast near Cape Canaveral as NASA determines the next step. It remains the property of the U.S. government. The families of all seven Challenger crew members have been notified. "We want to make sure whatever we do, we do the right thing for the legacy of the crew," Ciannilli said.

New Drug Reverses Neural and Cognitive Effects of a Concussion (scitechdaily.com) 10

An anonymous reader quotes a report from SciTechDaily: ISRIB, a tiny molecule identified by the University of California, San Francisco (UCSF) researchers can repair the neural and cognitive effects of concussion in mice weeks after the damage, according to a new study. ISRIB blocks the integrated stress response (ISR), a quality control process for protein production that, when activated chronically, can be harmful to cells. The study, which was recently published in the Proceedings of the National Academy of Sciences, discovered that ISRIB reverses the effects of traumatic brain injury (TBI) on dendritic spines, an area of neurons vital to cognition. The drug-treated mice also showed sustained improvements in working memory.

The authors suggest that TBI triggers a persistent activation of the ISR, which in turn leads to the ongoing proliferation of transient spines that fail to support memory formation. Future experiments will explore whether ISRIB has similar effects on other cell types, brain areas, and cognitive tasks. ISR activation has been implicated in many neurological disorders, including Alzheimer's disease, Parkinson's disease, multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS). Thus, the researchers believe ISRIB may have therapeutic potential in multiple patient populations. While there was no evidence of the drug's toxicity in mice, clinical trials are currently evaluating the safety and effectiveness of ISRIB in humans.

Kaspersky To Kill Its VPN Service In Russia Next Week (bleepingcomputer.com) 17

Kaspersky is stopping the operation and sales of its VPN product, Kaspersky Secure Connection, in the Russian Federation, with the free version to be suspended as early as November 15, 2022. BleepingComputer reports: As the Moscow-based company informed on its Russian blog earlier this week, the shutdown of the VPN service will be staged, so that impact on customers remains minimal. Purchases of the paid version of Kaspersky Secure Connection will remain available on both the official website and mobile app stores until December 2022. Customers with active subscriptions will continue to enjoy the product's VPN service until the end of the paid period, which cannot go beyond the end of 2023 (one-year subscription).

Russian-based users of the free version of Kaspersky Secure Connection will not be able to continue using the product after November 15, 2022, so they will have to seek alternatives. BleepingComputer emailed Kaspersky questions regarding its decision to stop offering VPN products in Russia, but a spokesperson has declined to provide more information.
Russia's telecommunications watchdog, Roskomnadzor, announced VPN bans in June 2021 and then again in December 2021. "The reason for banning 15 VPNs in the country was because their vendors refused to connect their services to the FGIS database, which would apply government-imposed censorship in VPN connections, and would also make user traffic and identity subject to state scrutiny," reports BleepingComputer.

"Ever-increasing controls are strangling VPN usage in Russia. On Tuesday, the Ministry of Digital Transformation requested all state-owned companies to declare what VPN products they use, for what purposes, and in what locations."

How Mem Plans To Reinvent Note-Taking Apps With AI (theverge.com) 15

David Pierce writes via The Verge: In the summer of 2019, Kevin Moody and Dennis Xu started meeting with investors to pitch their new app. They had this big idea about reshaping the way users' personal information moves around the internet, coalescing all their data into a single tool in a way that could actually work for them. But they quickly ran into a problem: all of their mock-ups and descriptions made it seem like they were building a note-taking app. And even in those hazy early days of product development -- before they had a prototype, a design, even a name -- they were crystal clear that this would not be a note-taking app. Instead, the founders wanted to create something much bigger. It would encompass all of your notes but also your interests, your viewing history, your works-in-progress. "Imagine if you had a Google search bar but for all nonpublic information," Xu says. "For every piece of information that was uniquely relevant to you."

That's what Moody and Xu were actually trying to build. So they kept tweaking the approach until it made sense. At one point, their app was going to be called NSFW, a half-joke that stood for "Notes and Search for Work," and for a while, it was called Supernote. But after a few meetings and months, they eventually landed on the name "Mem." Like Memex, a long-imagined device that humans could use to store their entire memory. Or like, well, memory. Either way, it's not a note-taking app. It's more like a protocol for private information, a way to pipe in everything that matters to you -- your email, your calendar events, your airline confirmations, your meeting notes, that idea you had on the train this morning -- and then automatically organize and make sense of it all. More importantly, it's meant to use cutting-edge AI to give all that information back to you at exactly the right time and in exactly the right place. [...]

So far, Mem is mostly a note-taking app. It's blisteringly fast and deliberately sparse -- mostly just a timeline of every mem (the company's parlance for an individual note) you've ever created or viewed, with a few simple ways to categorize and organize them. It does tasks and tags, but a full-featured project manager or Second Brain system this is not. But if you look carefully, the app already contains a few signs of where Mem is headed: a tool called Writer that can actually generate information for you, based on both its knowledge of the public internet and your personal information; AI features that summarize tweet threads for you; a sidebar that automatically displays mems related to what you're working on. All this still barely scratches the surface of what Mem wants to do and will need to do to be more than a note-taking app...

FTX Assets Frozen By Bahamian Regulator (coindesk.com) 9

Bahamian regulators have frozen the assets of FTX Digital Markets and related parties, calling it a "prudent course of action" to "preserve assets and stabilize the company," according to a press release on Thursday. CoinDesk reports: The Securities Commission of the Bahamas also suspended FTX's registration and appointed an attorney -- Brian Sims, a senior partner at Lennox Paton -- as a provisional liquidator of the assets. FTX is based in the Bahamas and is a separate entity from FTX US.

"The commission is aware of public statements suggesting that clients' assets were mishandled, mismanaged and/or transferred to Alameda Research. Based on the commission's information, any such actions would have been contrary to normal governance, without client consent and potentially unlawful," the commission said in its release.

WeWork Will Close About 40 Locations As Losses Narrow (nytimes.com) 31

WeWork said Thursday that it was going to close roughly 40 "underperforming" locations in the United States and tempered its revenue forecast for the year, highlighting the challenges the co-working company still faces after its near collapse and subsequent bailout in 2019. The New York Times reports: For the third quarter, WeWork said it lost $568 million, an improvement from the same period last year, when it lost $802 million. Revenue of $817 million in the latest quarter was more than 20 percent higher than the $661 million reported a year earlier. WeWork does not own its buildings but leases office space and parcels it out to its customers, which include individuals, small businesses and larger companies. Memberships rose in the third quarter. But occupancy was only slightly higher in WeWork's 647 consolidated locations around the world, rising to 71 percent in the third quarter from 70 percent in the second.

The company said it expected revenue of $3.35 billion to $3.37 billion this year. The upper end of that forecast is lower than the forecast it issued last quarter, when WeWork projected up to $3.5 billion in 2022 revenue. One factor leading to the pared back forecast, the company said, was "slower than expected growth" in its operations in the United States, Canada and Japan. WeWork said closing the locations was likely to reduce revenue but would benefit the company by cutting costs. The company has lost more than $12 billion since the end of 2018.

Demand for office space has plummeted since companies started letting employees work from home during the pandemic. But WeWork considers this trend an opportunity. Because it offers space for shorter periods than traditional landlords, the company has claimed that it provides businesses more flexibility. "The headwinds in the office sector are really benefiting the flex model," Sandeep Mathrani, WeWork's chief executive, said Thursday on a call to discuss third-quarter results. Still, large companies' share of memberships has fallen, to 47 percent in the third quarter from 49 percent a year earlier. The enormous costs of WeWork's office leases and the expenses involved in running the locations have led many investors to express skepticism about WeWork's turnaround plan. The company's stock has lost more than three-quarters of its value since WeWork went public last year, giving it a market capitalization of $1.9 billion, a small fraction of the $47 billion value that private investors placed on the company in 2019.

Amazon Introduces 'Sparrow' Robotic Arm That Can Do Repetitive Warehouse Tasks (cnbc.com) 24

An anonymous reader quotes a report from CNBC: Amazon on Thursday showed off a new robot that could one day assist warehouse workers with some of the more tedious aspects of the job. The company unveiled "Sparrow," a robotic arm that can pluck millions of items of varying shapes and sizes, on stage at the Delivering the Future conference near Boston, where it showcased new robotics, transportation and last-mile delivery technologies. Amazon says Sparrow uses computer vision and artificial intelligence to move products before they're packaged. A video of Sparrow shows the robotic arm picking up a board game, a bottle of vitamins and a set of sheets -- all the kinds of items that might flow through one of the company's warehouses -- and deftly placing them in crates.

Suction cups attached to the surface of the robot allow it to firmly grasp items. Previous iterations of robotic arms have been able to pick up boxes, which are generally uniform in their shape but might vary in size. But Sparrow is capable of handling items with varying curvature and size, said Jason Messinger, principal technical product manager of robotic manipulation at Amazon Robotics, in a demonstration. "This is not just picking the same things up and moving it with high precision, which we've seen in previous robots," Messinger said. The robotic arm can identify around 65% of Amazon's product inventory, the company said.

While the introduction of robots to the warehouse often raises questions about whether human jobs will be replaced, Amazon says Sparrow will "take on repetitive tasks," freeing employees up to focus on other things. The company also said the technology can improve safety in the workplace, although that prospect has been debated. An investigation by Reveal from the Center for Investigative Reporting found the company's warehouses with robots have higher injury rates than facilities without automation.

NSA Urges Organizations To Shift To Memory Safe Programming Languages (nsa.gov) 100

In an press release published earlier today, the National Security Agency (NSA) says it will be making a strategic shift to memory safe programming languages. The agency is advising organizations explore such changes themselves by utilizing languages such as C#, Go, Java, Ruby, or Swift. From the report: The "Software Memory Safety" Cybersecurity Information Sheet (PDF) highlights how malicious cyber actors can exploit poor memory management issues to access sensitive information, promulgate unauthorized code execution, and cause other negative impacts. "Memory management issues have been exploited for decades and are still entirely too common today," said Neal Ziring, Cybersecurity Technical Director. "We have to consistently use memory safe languages and other protections when developing software to eliminate these weaknesses from malicious cyber actors."

Microsoft and Google have each stated that software memory safety issues are behind around 70 percent of their vulnerabilities. Poor memory management can lead to technical issues as well, such as incorrect program results, degradation of the program's performance over time, and program crashes. NSA recommends that organizations use memory safe languages when possible and bolster protection through code-hardening defenses such as compiler options, tool options, and operating system configurations.

Studio Ghibli Is Teaming Up With Lucasfilm (polygon.com) 10

Studio Ghibli, the beloved animation producer behind worldwide hits like Spirited Away, Ponyo, My Neighbor Totoro, and Grave of the Fireflies, is teaming up with Lucasfilm, home to the Star Wars and Indiana Jones franchises, for a mysterious new project. Polygon reports: On Thursday, the Japanese studio tweeted a cryptic video teaser, with the Lucasfilm and Studio Ghibli logos back to back and... maddeningly nothing else. The video is silent, so there are no John Williams-penned themes to work from here. But suffice it to say, the teaser is most likely for an animated project based on a Lucasfilm property, and Star Wars seems like a safe bet. Lucasfilm and Disney have multiple animated Star Wars series, including the recently released Tales of the Jedi and -- the most likely candidate for Studio Ghibli -- Star Wars: Visions.

A second season of Star Wars: Visions is coming to Disney Plus in spring 2023. And while Disney and Lucasfilm have not revealed much about who is contributing to it, Star Wars: Visions Volume 2 is pitched as a "global tour, celebrating the incredible animation happening across countries and cultures."

Police Use DNA Phenotyping To Limit Pool of Suspects To 15,000 (vice.com) 29

An anonymous reader quotes a report from Motherboard: The Queensland, Australia police have used DNA phenotyping for the first time ever in hopes of leading to a breakthrough for a 1982 murder. The department partnered with a U.S.-based company called Parabon NanoLabs to create a profile image of the murder suspect, a Caucasian man with long blonde hair. Police claim that this image was generated using blood samples found at the scene of the murder of a man from 40 years ago; according to the Australian Broadcasting Corporation this is the first time "investigative genetic genealogy" has been used in Queensland.

This image does not factor in any environmental characteristics, such as tattoos, facial hair, and scars, and cannot determine the age or body mass of the suspect. However, Queensland investigators have published the image online and are offering a $500,000 reward and indemnity from prosecution to anyone who might have information about the suspect. The image is a vague rendering of a man that does not provide any more information than the sketch that the department already has of the suspect. This further perpetuates the hyper-surveillance of any man who resembles the image. Parabon NanoLabs has already been criticized by criminal justice and privacy experts for disseminating images that implicate too broad a pool of suspects.

The Queensland police department said that the DNA sample from the case generated a genealogy tree of "15,000 'linked' individuals" and they have not been able to find a close match yet. Instead of facing the possibility that DNA phenotyping may not be an effective tool for narrowing down a suspect, the police department's strategy is to ask the public for their DNA samples. Criminologist Xanthe Mallett said in a press release that to help police find a match, people can "opt-in" to share their own DNA samples with investigators through DNA services such as Family Tree and GEDMatch.
"Many members of the public that see this generated image will be unaware that it's a digital approximation, that age, weight, hairstyle, and face shape may be very different, and that accuracy of skin/hair/eye color is approximate," said Callie Schroeder, the Global Privacy Counsel at the Electronic Privacy Information Center.

Intel Takes on AMD and Nvidia With Mad 'Max' Chips For HPC (theregister.com) 11

Intel's latest plan to ward off rivals from high-performance computing workloads involves a CPU with large stacks of high-bandwidth memory and new kinds of accelerators, plus its long-awaited datacenter GPU that will go head-to-head against Nvidia's most powerful chips. From a report: After multiple delays, the x86 giant on Wednesday formally introduced the new Xeon CPU family formerly known as Sapphire Rapids HBM and its new datacenter GPU better known as Ponte Vecchio. Now you will know them as the Intel Xeon CPU Max Series and the Intel Data Center GPU Max Series, respectively, which were among the bevy of details shared by Intel today, including performance comparisons. These chips, set to arrive in early 2023 alongside the vanilla 4th generation Xeon Scalable CPUs, have been a source of curiosity within the HPC community for years because they will power the US Department of Energy's long-delayed Aurora supercomputer, which is expected to become the country's second exascale supercomputer and, consequently, one of the world's fastest.

In a briefing with journalists, Jeff McVeigh, the head of Intel's Super Compute Group, said the Max name represents the company's desire to maximize the bandwidth, compute and other capabilities for a wide range of HPC applications, whose primary users include governments, research labs, and corporations. McVeigh did admit that Intel has fumbled in how long it took the company to commercialize these chips, but he tried to spin the blunders into a higher purpose. "We're always going to be pushing the envelope. Sometimes that causes us to maybe not achieve it, but we're doing that in service of helping our developers, helping the ecosystem to help solve [the world's] biggest challenges," he said. [...] The Xeon Max Series will pack up to 56 performance cores, which are based on the same Golden Cove microarchitecture features as Intel's 12th-Gen Core CPUs, which debuted last year. Like the vanilla Sapphire Rapids chips coming next year, these chips will support DDR5, PCIe 5.0 and Compute Express Link (CXL) 1.1, which will enable memory to be directly attached to the CPU over PCIe 5.0.

NASA Launched an Inflatable Flying Saucer, Then Landed It in the Ocean (nytimes.com) 21

On Thursday morning, NASA sent a giant inflatable device to space and then brought it back down from orbit, splashing in the ocean near Hawaii. From a report: You might think of it as a bouncy castle from space, although the people in charge of the mission would prefer you did not. "I would say that would be inaccurate," Neil Cheatwood, principal investigator for the Low-Earth Orbit Flight Test of an Inflatable Decelerator, or LOFTID for short, said of the comparison during an interview. LOFTID may sound like just an amusing trick, but the $93 million project demonstrates an intriguing technology that could help NASA in its goal of getting people safely to the surface of Mars someday. The agency has landed a series of robotic spacecraft on Mars, but the current approaches only work for payloads weighing up to about 1.5 tons -- about the bulk of a small car. That is inadequate for the larger landers, carrying 20 tons or more, that are needed for people and the supplies they will need to survive on the red planet.

A more accurate description of the device might be that it is a saucer, 20 feet wide when inflated. It is made of layers of fabric that can survive falling into the atmosphere at 18,000 miles per hour and temperatures close to 3,000 degrees Fahrenheit. Still, an inflatable heat shield shares a key characteristic with a bouncy castle: Uninflated, it can be folded and packed tightly. LOFTID fit in a cylinder a bit over four feet wide and one and a half feet high. For a traditional rigid heat shield, there is no way to cram something 20 feet in diameter into a rocket that is not that wide. A larger surface like LOFTID's generates much more air friction -- essentially it is a better brake as it slices through the upper atmosphere, and the greater drag allows heavier payloads to be slowed down. For future Mars missions, the inflatable heat shield would be combined with other systems like parachutes and retrorockets to guide the lander en route to a soft landing.

Google Play To Pilot Third-Party Billing in New Markets Including US (techcrunch.com) 13

Google today announced it's expanding its user choice billing pilot, which allows Android app developers to use other payment systems besides Google's own. The program will now become available to new markets, including the U.S., Brazil and South Africa, and Bumble will now join Spotify as one of the pilot testers. From a report: Google additionally announced Spotify will now begin rolling out its implementation of the program starting this week. The company had first announced its intention to launch a third-party billing option back in March of this year, with Spotify as the initial tester. Since then, the program has steadily expanded. Last month, for example, Google invited other non-game developers to apply for the user choice billing program in select markets, including India, Australia, Indonesia, Japan and the European Economic Area (EEA). The company also introduced a similar policy for developers in the EEA region in July, but the new guidelines raised the commission discount from 3% to 4% for developers who opted in. With today's expansion, user choice billing will be made available to 35 countries worldwide. Google says it's been working with Spotify to help develop the experience and now the streaming music service will begin to put the new features into action in supported markets. The experience could still change over time, Google warned, as this is still the early days of the pilot test.
