Researchers have announced the discovery of an astronomical object called GPM J1839-10, which emits regular bursts of radio energy similar to a pulsar but with a much longer interval between pulses of 21 minutes. The nature and physics behind this behavior remain unknown, as it does not fit into any existing astronomical categories or explanations, making it a unique and enigmatic phenomenon that requires further study and observation. Ars Technica reports: GPM J1839-10 was discovered in a search of the galactic plane for transient objects -- something that's not there when you first look, but appears the next time you check. The typical explanation for a transient object is something like a supernova, where a major event gives something an immense boost in brightness. They're found at the radio end of the spectrum, fast radio bursts, but are also very brief and, so, fairly difficult to spot. In any case, GPM J1839-10 showed up in the search in a rather unusual way: It showed up as a transient item twice in the same night of observation. Rather than delivering a short burst of immense energy, such as a fast radio burst, GPM J1839-10 was much lower energy and spread out over a 30-second-long burst.

Follow-on observations showed that the object repeated pretty regularly, with a periodicity of about 1,320 seconds (more commonly known as 22 minutes). There's a window of about 400 seconds centered on that periodicity, and a burst can appear anywhere within the window and will last anywhere from 30 to 300 seconds. While active, the intensity of GPM J1839-10 can vary, with lots of sub-bursts within the main signal. Occasionally, a window will also go by without any bursts. A search through archival data showed that signals had been detected at the site as far back as 1988. So, whatever is producing this signal is not really a transient, in the sense that the phenomenon that's producing these bursts isn't a one-time-only event. The list of known objects that can produce this sort of behavior is short and consists of precisely zero items. [...]

So, given that every possible explanation is terrible, where do we go from here? The good news is that these objects will be so difficult to spot that it's possible there are a lot more out there that we've overlooked. The bad news is that they're still hard to spot. The length of the burst -- up to 300 seconds -- and the gap between bursts mean short-cadence observations will likely either see something there the whole time or miss it entirely. We'd really need to have hardware stare at a single area of space for a half-hour or more, and to have its staring divided up into multiple exposures, to be sure we catch it in both its on and off states. And that involves a major commitment of hardware. In the meantime, we can potentially narrow down the location of GPM J1839-10 to try to see if there's anything interesting in other wavelengths. Since this is located within the galactic plane, however, that's going to be challenging as well.

Kevin Mitnick, once the so-called "most wanted computer criminal in US history," died on Sunday. He was 59. The New York Times adds: The cause was complications from pancreatic cancer. He had been undergoing treatment at the University of Pittsburgh Medical Center following his diagnosis more than a year ago, according to the King David Memorial Chapel & Cemetery in Las Vegas. After serving prison time for breaking into and tampering with corporate computer networks, he was released in 2000 and began a new career as a security consultant, writer and public speaker.

Mr. Mitnick was best known for the crime spree during the 1990s that involved the theft of thousands of data files and credit card numbers from computers across the country. He used his skills to work his way into the nation's phone and cell networks, vandalizing government, corporate and university computer systems. Investigators at the time named him the "most wanted" computer hacker in the world.

In 1995, after a more than two-year-long manhunt, Mr. Mitnick was captured by the F.B.I. and charged with the illegal use of a telephone access device and computer fraud. "He allegedly had access to corporate trade secrets worth millions of dollars. He was a very big threat," Kent Walker, a former assistant U.S. attorney in San Francisco, said at the time. In 1998, while Mr. Mitnick awaited sentencing, a group of supporters commandeered The New York Times website for several hours, forcing it to shut down. The next year, Mr. Mitnick pleaded guilty to computer and wire fraud as part of an agreement with prosecutors and was sentenced to 46 months in prison. He was also prohibited from using a computer or cellphone without the permission of his probation officer for the three years following his release.
From an obituary: Kevin was an original; much of his life reads like a fiction story. The word that most of us who knew him would use -- magnificent.

He grew up brilliant and restless in the San Fernando Valley in California, an only child with a penchant for mischief, a defiant attitude toward authority, and a love for magic. Kevin's intelligence and delight in holding the rapt attention of audiences revealed themselves early in his childhood and continued throughout his life. In time, he transitioned from pranks and learning magic tricks to phone phreaking, social engineering, and computer hacking.

When his desire to push boundaries led him too far astray, he landed in juvenile detention and eventually served a couple of stints in prison. His time on the FBI's Most Wanted List was well documented in his New York Times bestselling book, The Ghost in the Wires: My Adventures as the World's Most Wanted Hacker, and his other titles: The Art of Deception, The Art of Intrusion, both co-authored with William Simon, and The Art of Invisibility with Robert Vamosi.

Kevin emerged from his final prison term, which he deemed a 'vacation,' in January 2000. He was a changed individual, and began constructing a new career, as a White Hat hacker and security consultant. He became a highly sought-after global public speaker, a writer, and established the successful Mitnick Security Consulting. In November 2011, he became the Chief Hacking Officer and part owner of security awareness training company KnowBe4, founded by close friend and business partner Stu Sjouwerman.

An anonymous reader quotes a report from Engadget: Fervo Energy says it has achieved a breakthrough in geothermal technology. It carried out a 30-day well test at its site in northern Nevada and says it was able to achieve a "flowrate of 63 liters per second at high temperature that enables 3.5 megawatts of electric production." The company says the test resulted in flow and power output records for an enhanced geothermal system (EGS) and that it was completed without incident. A megawatt can power around 750 homes at once. Fervo is expected to connect its Project Red site to the grid this year. It will be used to power Google data centers and some of the company's other Nevada infrastructure. Google and Fervo signed an agreement in 2021 to develop a "next-generation geothermal power project."

This is the first time an energy company has shown that an EGS can work on a commercial scale, according to Bloomberg. It's been a long road to reach this point, as scientists have been trying to make EGS a reality since the 1970s. [...] Fervo says it's the first company to "successfully drill a horizontal well pair for commercial geothermal production, achieving lateral lengths of 3,250 feet, reaching a temperature of 191C, and proving controlled flow through rigorous tracer testing." The company is hoping to replicate its success at a site in Utah. If Fervo sees similar results there and it successfully implements design upgrades to maximize output, the site is expected to generate enough electricity to power 300,000 homes simultaneously, Latimer said. That's around a quarter of all homes in Utah.

sciencehabit shares a report from Science: This week, the much anticipated movie Oppenheimer hits theaters, giving famed filmmaker Christopher Nolan's take on the theoretical physicist who during World War II led the Manhattan Project to develop the first atomic bomb. J. Robert Oppenheimer, who died in 1967, is known as a charismatic leader, eloquent public intellectual, and Red Scare victim who in 1954 lost his security clearance in part because of his earlier associations with suspected Communists. To learn about Oppenheimer the scientist, Science spoke with David C. Cassidy, a physicist and historian emeritus at Hofstra University. Cassidy has authored or edited 10 books, including J. Robert Oppenheimer and the American Century. How did Oppenheimer compare to Einstein? Did he actually make any substantiative contributions to THE Bomb? And why did he eventually lose his security clearance?

Today, Nissan announced it's adopting Tesla's North American Charging Standard (NACS) in its electric vehicles, following in the footsteps of Ford, GM, Rivian, Mercedes-Benz, Volvo, and Polestar. Ars Technica reports: "Adopting the NACS standard underlines Nissan's commitment to making electric mobility even more accessible as we follow our Ambition 2030 long-term vision of greater electrification," said Jeremie Papin, chairperson of Nissan Americas. "We are happy to provide access to thousands more fast chargers for Nissan EV drivers, adding confidence and convenience when planning long-distance journeys."

This is actually Nissan's second time changing its DC fast-charging plugs. An early pioneer of EVs with the first- and then second-generation Leaf, it chose the CHAdeMO standard for those models, which is popular in Japan but never really caught on elsewhere. But when Nissan built the Ariya crossover as its third-generation EV, it dropped CHAdeMO for CCS, which appeared like it was going to win the charging standard war by dint of having every OEM onboard other than Tesla. CCS may have had the power of numbers in terms of OEMs, but EVs from all those makes are still heavily outnumbered on the road by the sheer mass of Models 3 and Y, and it's hard to argue with the superiority of Tesla's Supercharger network, either in terms of reliability or number of deployed chargers.

A year after its largest quarterly loss and a significant drop in subscribers, Netflix has made a remarkable recovery by adding 5.9 million global subscribers in the second quarter of 2023, surpassing analyst expectations. TechCrunch reports: The subscriber addition far exceeds industry guidance; analysts forecasted an increase of 1.7 million subs. Netflix ended Q1 with 232.5 million users. Netflix's quarterly earnings results arrive a few hours after news broke out that the streamer dropped its basic plan in the U.S. and the U.K.

Netflix's significant subscriber gain this quarter reflects the impact of its paid sharing rules. Netflix wrote in its letter to shareholders, "In May, we successfully launched paid sharing in 100+ countries, representing more than 80% of our revenue base." The company added that today it's rolling out paid sharing to "almost all the remaining countries," including Croatia, Kenya, Indonesia and India. Netflix reported $8.2 billion in revenue and a net income of $1.5 billion.

An anonymous reader quotes a report from the BBC: An open letter signed by more than 1,300 experts says AI is a "force for good, not a threat to humanity." It was organized by BCS, the Chartered Institute for IT, to counter "AI doom." Rashik Parmar, BCS chief executive, said it showed the UK tech community didn't believe the "nightmare scenario of evil robot overlords." In March, tech leaders including Elon Musk, who recently launched an AI business, signed a letter calling for a pause in developing powerful systems. That letter suggested super-intelligent AI posed an "existential risk" to humanity.

But the BCS sees the situation in a more positive light, while still supporting the need for rules around AI. Richard Carter is a signatory to the BCS letter. Mr Carter, who founded an AI-powered startup cybersecurity business, feels the dire warnings are unrealistic: "Frankly, this notion that AI is an existential threat to humanity is too far-fetched. We're just not in any kind of a position where that's even feasible." Signatories to the BCS letter come from a range of backgrounds -- business, academia, public bodies and think tanks, though none are as well known as Elon Musk, or run major AI companies like OpenAI.

Those the BBC has spoken to stress the positive uses of AI. Hema Purohit, who leads on digital health and social care for the BCS, said the technology was enabling new ways to spot serious illness, for example medical systems that detect signs of issues such as cardiac disease or diabetes when a patient goes for an eye test. She said AI could also help accelerate the testing of new drugs. Signatory Sarah Burnett, author of a book on AI and business, pointed to agricultural uses of the tech, from robots that use artificial intelligence to pollinate plants to those that "identify weeds and spray or zap them with lasers, rather than having whole crops sprayed with weed killer." The letter argues: "The UK can help lead the way in setting professional and technical standards in AI roles, supported by a robust code of conduct, international collaboration and fully resourced regulation." By doing so, it says Britain "can become a global byword for high-quality, ethical, inclusive AI."

A bipartisan pair of senators unveiled a bill Wednesday to ban stock ownership by lawmakers and administration officials. The Hill reports: The bill, introduced by Sens. Kirsten Gillibrand (D-N.Y.) and Josh Hawley (R-Mo.), would establish firmer stock trading bans and disclosure requirements for lawmakers, senior executive branch officials and their spouses and dependents. The bill would ban congressional members, the president, vice president, senior executive branch members, and their spouses and dependents from holding or trading stocks, with no exception to blind trusts. Congressional members who violate this ban would be required to pay at least 10 percent of the banned investments.

The legislation also establishes harsh penalties for executive branch stock trading, requiring executive branch officials to give up profits from covered finance interests to the Department of Treasury, while also facing a fine from the Automatic Special Counsel. Congressional members, senior congressional staff and senior executive branch employees would also be required to report if they, a spouse or a dependent applies for or receives a "benefit of value" from the federal government, including loans, contracts, grants, agreements and payments. If they fail to file, they will face a $500 penalty.

The bill aims to increase transparency, requiring public databases of personal financial disclosures and financial transaction filings required by the STOCK Act, which prohibits members of Congress from using insider information when buying and selling stocks. The penalty for the failing to file STOCK Act transaction reports would also increase from $200 to $500.

You now have a new way to connect your Windows PC to an Android device to share files: Nearby Share, an app Google released Wednesday and which will be bundled with upcoming PCs. From a report: As the name suggests, Nearby Share allows you to share files back and forth between Android devices and PCs. It's similar to Apple's AirDrop, with the key difference being that Nearby Share connects devices from two different companies, rather than iPhones and Macs. Google released the beta version of Nearby Share earlier this year.

Nearby Share connects your phone to your PC, but it can also be used for you to send files and photos to nearby Android phones that you don't use, as well as to nearby PCs. That makes it handy for simply sharing a photo at a concert, or dropping a file onto a friend's PC without hassle. You'll just need to be within about 16 feet to do so, Google says. Why use Nearby Share? Google's unspoken argument is that it's simpler to do so. There are already numerous ways to view and transfer files and photos from Android phones to PCs, from the tried-and-true sneakerware to uploading and downloading from the cloud, to more modern approaches like Microsoft's Your Phone, now called Phone Link. Device makers like Samsung also have released their own specific versions for Galaxy devices. Google, though, made its mark with Gmail and search, both functions that worked more simply and effectively than other solutions.

Microsoft is expanding its suite of free security tools for customers, the software company said on Wednesday, following criticism that it was charging clients to protect themselves against Microsoft's mistakes. From a report: The move follows a high-level hack that allowed allegedly Chinese spies to steal emails from senior U.S. officials - and complaints from security specialists and lawmakers against paying for tools In a blog post published on Wednesday, Microsoft said the advanced features in Microsoft's auditing suite - which it calls Microsoft Purview - would be available to all customers "over the coming months." Although not enough to prevent hacks on their own, digital auditing tools are critical for helping organizations figure out whether intruders are in their network, how they got in and how to get them out.

Blizzard Entertainment is bringing its PC games to Steam, starting with the release of Overwatch 2 on Valve's digital storefront on Aug. 10, Blizzard announced Wednesday. Polygon reports: The Windows PC version of Overwatch 2, like many of Blizzard's PC games, is currently only available through Battle.net. But with Microsoft's impending acquisition of Activision Blizzard and declining player engagement in the game, the maker of Diablo, Warcraft, and Overwatch appears to be changing its strategy. Blizzard says it will bring "a selection" of its games to Steam, but did not specify which titles beyond Overwatch 2 will make the jump from Battle.net. (A few classic Blizzard games, including the original Diablo and the first two Warcraft games, are available through GOG.com.)

The acceptance of Steam as a platform for Blizzard's games is part of the studio's evolution, the company said in a blog post. "[O]ne of the ideas pushing us forward is meeting players around the world where they are, and making our games as easy as possible to access and play," the company said. "We want to give everyone a chance to experience our universes with old friends while making new ones, no matter how they choose to play." In its announcement, Blizzard said it's not moving away from Battle.net. But, it explained, "as we've evolved, the industry has evolved too -- gaming is no longer just for specific communities as it was when Battle.net launched over two decades ago, gaming is for everyone -- and though we remain committed to continually investing in and supporting Battle.net, we want to break down the barriers to make it easier for players everywhere to find and enjoy our games."

Blizzard says that players on Steam will still need a Battle.net account connected to Overwatch 2 to play the game. The Steam version will support Steam achievements and friends lists, but Blizzard did not announce Steam Deck support. Overwatch 2 can now be wishlisted through Steam. As for Blizzard's future plans for other game releases on Steam, the company said it will be "sharing more about potential other games coming to the platform when the time is right."

An anonymous reader quotes a ArsTechnica report: On Wednesday, two German researchers, Sophie Jentzsch and Kristian Kersting, released a paper that examines the ability of OpenAI's ChatGPT-3.5 to understand and generate humor. In particular, they discovered that ChatGPT's knowledge of jokes is fairly limited: During a test run, 90 percent of 1,008 generations were the same 25 jokes, leading them to conclude that the responses were likely learned and memorized during the AI model's training rather than being newly generated. The two researchers, associated with the Institute for Software Technology, German Aerospace Center (DLR), and Technical University Darmstadt, explored the nuances of humor found within ChatGPT's 3.5 version (not the newer GPT-4 version) through a series of experiments focusing on joke generation, explanation, and detection. They conducted these experiments by prompting ChatGPT without having access to the model's inner workings or data set.

"To test how rich the variety of ChatGPT's jokes is, we asked it to tell a joke a thousand times," they write. "All responses were grammatically correct. Almost all outputs contained exactly one joke. Only the prompt, 'Do you know any good jokes?' provoked multiple jokes, leading to 1,008 responded jokes in total. Besides that, the variation of prompts did not have any noticeable effect." [...] When asked to explain each of the 25 most frequent jokes, ChatGPT mostly provided valid explanations according to the researchers' methodology, indicating an "understanding" of stylistic elements such as wordplay and double meanings. However, it struggled with sequences that didn't fit into learned patterns and couldn't tell when a joke wasn't funny. Instead, it would make up fictional yet plausible-sounding explanations.

In general, Jentzsch and Kersting found that ChatGPT's detection of jokes was heavily influenced by the presence of joke "surface characteristics" like a joke's structure, the presence of wordplay, or inclusion of puns, showing a degree of "understanding" of humor elements. Despite ChatGPT's limitations in joke generation and explanation, the researchers pointed out that its focus on content and meaning in humor indicates progress toward a more comprehensive research understanding of humor in language models: "The observations of this study illustrate how ChatGPT rather learned a specific joke pattern instead of being able to be actually funny," the researchers write. "Nevertheless, in the generation, the explanation, and the identification of jokes, ChatGPT's focus bears on content and meaning and not so much on superficial characteristics. These qualities can be exploited to boost computational humor applications. In comparison to previous LLMs, this can be considered a huge leap toward a general understanding of humor."

An anonymous reader shares a report: In March 2020, as the Covid-19 pandemic began to transform the world, the company then known as Facebook struck a deal to buy all the augmented reality displays made by British firm Plessey. At the time, the deal appeared to be a savvy way of squeezing out Apple in the competition to develop AR glasses, as Plessey was one of the few makers of AR displays. Three years on, however, the deal has turned into a bust for Meta. Development of Plessey's technology has stalled, say people with direct knowledge of the effort. Facebook, now called Meta Platforms, has struggled to make Plessey's displays bright enough for use in its AR glasses under development and to reduce defects that crop up in the manufacturing process. Earlier this year, Meta decided to abandon Plessey's microLED tech in favor of an older display technology, liquid crystal on silicon or LCoS. The decision is one of several Meta has made, for either technological or cost-saving reasons, that will reduce the edge that the AR glasses have over existing AR headsets like Microsoft's HoloLens.

The episode highlights the twists and turns Meta is navigating as it tries to stay ahead of Apple and other rivals in the still-developing market for AR and virtual reality. Meta was early to the VR market with its Quest headsets and has been working on developing AR glasses to get ahead of rivals like Snap which are trying to develop similar products. Now it faces competition from Apple, which last month unveiled its mixed-reality headset, the Vision Pro, which will be available early next year. At the same time, Meta is under pressure from investors to curb the more than $10 billion it is spending annually at the Reality Labs division developing its AR and VR products. Technical setbacks have forced Meta to delay the timeline for releasing AR glasses multiple times, and it isn't anticipating releasing a pair of AR glasses to the public until at least 2027.

An anonymous reader shares a report: Danny Sullivan, Google's Search Liaison, responded to Vox Media's claim that AI content is currently "well-received by search engines." Sullivan said, "It's still not correct that AI content will be "well-received by search engines," at least for us." Sullivan went on to explain on Twitter that "There's lots of AI content on the web that doesn't rank well and hence isn't well received" by Google Search. "AI content has no magic ranking powers," Sullivan said. Only "if content is helpful, then it might succeed," but not because AI wrote it does it mean the content is helpful.

Sullivan wrote to the author, "FYI about this part: "he's learned that AI content 'will, at least for the moment, be well-received by search engines'." This isn't correct. Our systems are looking at the helpfulness of content, rather than how it is produced," Danny Sullivan clarified. "We'd encourage publishers, however they produce content, to ensure they're making it for people-first," he added. "Producing a lot of content with the primary purpose of ranking in search, rather than for people, should be avoided. Sites producing a lot of unhelpful content not intended for people-first may find all of their content less likely to be successful with search," he said.

Following months of intense scrutiny of his scientific work, Marc Tessier-Lavigne announced Wednesday that he would resign as president of Stanford University after an independent review of his research found significant flaws in studies he supervised going back decades. From a report: The review, conducted by an outside panel of scientists, refuted the most serious claim involving Dr. Tessier-Lavigne's work -- that an important 2009 Alzheimer's study was the subject of an investigation that found falsified data and that Dr. Tessier-Lavigne had covered it up. The panel concluded that the claim, published in February by The Stanford Daily, the campus newspaper, "appear to be mistaken" and that there was no evidence of falsified data, or that Dr. Tessier-Lavigne had otherwise engaged in fraud.

But the review also stated that the 2009 study, conducted while he was an executive at the biotech company Genentech, had "multiple problems" and "fell below customary standards of scientific rigor and process," especially for a paper of such potential consequences. As a result of the review, Dr. Tessier-Lavigne said he would retract a 1999 paper that appeared in the journal Cell and two others that appeared in Science in 2001. Two other papers published in Nature, including the 2009 Alzheimer's study, would also undergo what was described as comprehensive correction. Stanford is known for its leadership in scientific research, and even though the claims involved work published before Dr. Tessier-Lavigne's arrival at the university in 2016, the allegations reflected poorly on the university's integrity.
