A 27-year old Tamagotchi mystery was solved this week when a collector figured out how to unlock secret characters on the Mothra Tamagotchi, released in Japan in 1997. From a report: A Discord user named rhubarb_pie found out how to unlock the "Moll & Lora" twins as playable characters, which were previously seen in the handheld pet-raising-simulator as medical nurses who healed your character when it was sick. The Tamagotchi Wiki states they had previously been obtained through a "battery glitch," but rhubarb_pie figured out how to unlock them as playable characters through the normal course of gaming.

As a reminder, Tamagotchis are virtual pets made by Bandai and introduced in 1996 that were incredibly popular at the time and inspired a ton of clones. There have been many different versions of Tamagotchi since its original release, which included the Mothra Tamagotchi, which was tied to the Japanese release of the movie Rebirth of Mothra II. Mothra is a giant flying moth that exists in the Godzilla cinematic universe. There is an entire community of Tamagotchi collectors, enthusiasts, and reverse engineers, and for several decades players had wondered whether Moll & Lora could be unlocked as playable characters on the Mothra Tamagotchi. "After years of debate whether this was even possible, I have proven that, in fact, you can raise the Twin characters Moll & Lora on the Mothra," rhubarb_pie wrote in a lengthy guide to unlocking the characters posted on Discord Wednesday. "The ROM for the Mothra was dumped about a month ago and I figured out how everything worked by studying the code."

Retailers are struggling to rein in the proliferation of scammers tricking Americans into buying thousands of dollars' worth of gift cards. From a report: The Federal Trade Commission estimates that Americans lost at least $217 million to gift card scams last year. That number is likely higher, given many victims are too embarrassed to report to law enforcement. Cracking down on gift card scams was a hot topic this week at the National Retail Federation's (NRF) cybersecurity conference in Long Beach, California.

Some gift card scams start with texts from people pretending to be tech support, your boss, the government or a wrong number. Eventually, those conversations lead to someone asking the victim to buy gift cards on their behalf and send the barcode number to them via text. Others involve criminals in physical locations, tampering with a gift card to access the barcode information and then stealing the funds without taking the actual card. Each scam targets vulnerable populations: elderly, less-tech savvy people; those who are lonely and work from home; and even young kids, experts say.

Microsoft says it's making its new Recall feature in Windows 11 that screenshots everything you do on your PC an opt-in feature and addressing various security concerns. From a report: The software giant first unveiled the Recall feature as part of its upcoming Copilot Plus PCs last month, but since then, privacy advocates and security experts have been warning that Recall could be a "disaster" for cybersecurity without changes. Thankfully, Microsoft has listened to the complaints and is making a number of changes before Copilot Plus PCs launch on June 18th. Microsoft had originally planned to turn Recall on by default, but the company now says it will offer the ability to disable the controversial AI-powered feature during the setup process of new Copilot Plus PCs. "If you don't proactively choose to turn it on, it will be off by default," says Windows chief Pavan Davuluri.

An anonymous reader shares a report: Apple is expected to announce major artificial intelligence updates to the iPhone, iPad, and Mac next week during its Worldwide Developers Conference. Except Apple won't call its system artificial intelligence, like everyone else, according to Bloomberg's Mark Gurman on Friday. The system will reportedly be called "Apple Intelligence," and allegedly will be made available to new versions of the iPhone, iPad, and Mac operating systems. Apple Intelligence, which is shortened to just AI, is reportedly separate from the ChatGPT-like chatbot Apple is expected to release in partnership with OpenAI. Apple's in-house AI tools are reported to include assistance in message writing, photo editing, and summarizing texts. Bloomberg reports that some of these AI features will run on the device while others will be processed through cloud-based computing, depending on the complexity of the task. The name feels a little too obvious. While this is the first we're hearing of an actual name for Apple's AI, it's entirely unsurprising that Apple is choosing a unique brand to call its artificial intelligence systems.

California's proposed legislation to regulate AI has sparked a backlash from Silicon Valley heavyweights, who claim the bill will stifle innovation and force AI start-ups to leave the state. The Safe and Secure Innovation for Frontier Artificial Intelligence Systems Act, passed by the state Senate last month, requires AI developers to adhere to strict safety frameworks, including creating a "kill switch" for their models. Critics argue that the bill places a costly compliance burden on smaller AI companies and focuses on hypothetical risks. Amendments are being considered to clarify the bill's scope and address concerns about its impact on open-source AI models.

An anonymous reader shares a report: Two senior officials working for anti-terror police in Bangladesh allegedly collected and sold classified and personal information of citizens to criminals on Telegram, TechCrunch has learned. The data allegedly sold included national identity details of citizens, cell phone call records and other "classified secret information," according to a letter signed by a senior Bangladeshi intelligence official, seen by TechCrunch.

The letter, dated April 28, was written by Brigadier General Mohammad Baker, who serves as a director of Bangladesh's National Telecommunications Monitoring Center, or NTMC, the country's electronic eavesdropping agency. Baker confirmed the legitimacy of the letter and its contents in an interview with TechCrunch. "Departmental investigation is ongoing for both the cases," Baker said in an online chat, adding that the Bangladeshi Ministry of Home Affairs ordered the affected police organizations to take "necessary action against those officers." The letter, which was originally written in Bengali and addressed to the senior secretary of the Ministry of Home Affairs Public Security Division, alleges the two police agents accessed and passed "extremely sensitive information" of private citizens on Telegram in exchange for money.

Apple will introduce a new app called Passwords next week, aiming to simplify website and software logins for users, according to Bloomberg. The app -- offered as part of iOS 18, iPadOS 18, and macOS 15 -- will be unveiled at Apple's Worldwide Developers Conference on June 10. Powered by iCloud Keychain, Passwords will generate and manage passwords, allowing imports from rival services, and support Vision Pro headset and Windows computers.

The European Union's Copernicus Climate Change Service reported that the past year saw record-breaking heat, with global temperatures surpassing all historical measurements. According to Copernicus, May marked the 12th consecutive month of record-high global temperatures, and exceeded a key Paris Agreement temperature target. The Week reports: The stretch is a "stark warning." In a separate study published Wednesday, a group of 57 scientists found that human activity was responsible for 92% of 2023's warming, which increased at a rate "unprecedented in the instrumental record."

While averting catastrophe is "still just about possible," the decisions made by global leaders "especially in the next 18 months" will determine whether the planet can be saved, U.N. Secretary General Antonio Guterres said in a special address. "We need an exit ramp off the highway to climate hell."

Without serious efforts to reverse global warming, "this string of hottest months will be remembered as comparatively cold," Copernicus Director Carlo Buontempo said. "The 11 months in a row that tied or broke the 1.5C barrier did not yet constitute a breaching of the Paris target, since the benchmark refers to a timescale of multiple decades," notes Axios. "Still, the fact that the climate is now exceeding the target with greater regularity, and is projected to continue doing so, is a sign of the matter's urgency."

An anonymous reader quotes a report from New Atlas: The universe is awash with strange radio signals, but astronomers have now detected a really bizarre one that repeats every hour, cycling through three different states. While they have some ideas about its origin it can't be explained by our current understanding of physics. The signal first appeared in data gathered by the ASKAP radio telescope in Australia, which watches a big swath of sky at once for transient pulses. Officially designated ASKAP J1935+2148, the signal seems to repeat every 53.8 minutes. Whatever it is, the signal cycles through three different states. Sometimes it shoots out bright flashes that last between 10 and 50 seconds and have a linear polarization, meaning the radio waves all "point" in the same direction. Other times, its pulses are much weaker with a circular polarization, lasting just 370 milliseconds. And sometimes, the object misses its cue and stays silent.

So what could be behind such a weird radio signal? Let's get it out of the way up front: it's not aliens (probably). The most likely explanation, according to the scientists who discovered it, is that it's coming from a neutron star or a white dwarf. But it's not a neat solution, since the signal's weird properties don't fit with our understanding of the physics of those two kinds of objects. Neutron stars and white dwarfs are fairly similar, but with some key differences. They're both born from the deaths of bigger stars, with the original mass dictating whether you end up with a neutron star or a white dwarf. Neutron stars are known to blast radio waves out regularly, so they're a prime suspect here. It's possible that signals this varied could be produced by interactions between their strong magnetic fields and complex plasma flows. But there's a major problem: they usually spin at speeds of seconds or fractions of a second per revolution. It should be physically impossible for one to spin as slow as once every 54 minutes. White dwarfs, on the other hand, would have no problem spinning that slowly, but as the team says, "we don't know of any way one could produce the radio signals we are seeing here." "It might even prompt us to reconsider our decades-old understanding of neutron stars or white dwarfs; how they emit radio waves and what their populations are like in our Milky Way galaxy," added Caleb.

The findings have been published in the journal Nature Astronomy.

Longtime Slashdot reader destinyland shared a story from Space.com reporting on Boeing's missed opportunity to dock with the International Space Station, after five of the 28 thrusters that help control Starliner's movement in space stopped operating. NASA has since been able to recover four of the thrusters to successfully dock Boeing's Starliner capsule with the ISS. From the report: There are now two U.S.-built crew spacecraft docked with the ISS for the first time. Boeing's Starliner joined SpaceX's Dragon capsule "Endeavour," which arrived in March. Boeing's Starliner launched successfully on Wednesday to begin the crew flight test. The mission represents a final major step before NASA certifies Boeing to fly crew on operational missions. [...]

NASA flight controllers called off a previously scheduled approach to resolve issues with Starliner's propulsion system. Starliner has 28 jets, known as its reaction control system, or RCS, engines, that help the spacecraft make small movements in orbit. The crew on Starliner, NASA astronauts Butch Wilmore and Suni Williams, were told by NASA capsule communicator, or CAPCOM, Neal Nagata, that the 12:15 p.m. docking attempt had to be called off to resolve the spacecraft's propulsion issue. CAPCOM Nagata noted that the ISS has a zero fault tolerance for a spacecraft control problem.

The agency and Boeing had to troubleshoot five of the RCS jets that were not operating. Four of Starliner's malfunctioning jets were recovered after Wilmore and Williams worked with flight controllers to test fire the thrusters. CAPCOM Nagata had the astronauts hold the spacecraft beyond the "keep out sphere," an invisible boundary around the ISS that serves as a safety measure, while diagnosing the problematic thrusters.

An anonymous reader quotes a report from the New York Times: In a blow to publishers and authors, Costco plans to stop selling books regularly at stores around the United States, four publishing executives who had been informed of the warehouse retailer's plans said on Wednesday. Beginning in January 2025, the company will stop stocking books regularly, and will instead sell them only during the holiday shopping period, from September through December. During the rest of the year, some books may be sold at Costco stores from time to time, but not in a consistent manner, according to the executives, who spoke anonymously in order to discuss a confidential business matter that has not yet been publicly announced.

Costco's shift away from books came largely because of the labor required to stock books, the executives said. Copies have to be laid out by hand, rather than just rolled out on a pallet as other products often are at Costco. The constant turnaround of books -- new ones come out every Tuesday and the ones that have not sold need to be returned -- also created more work. The decision could be a significant setback for publishers at a moment when the industry is facing stagnant print sales and publishing houses are struggling to find ways to reach customers who have migrated online. Costco had already stopped selling books in some markets, including Alaska and Hawaii. While Costco may not be as critical of an outlet as a bookstore like Barnes & Noble, its influence is also evident in the large quantities it orders. When Costco chose to carry a book, "it often went big, ordering tens of thousands of copies at a minimum," says the report. "For major blockbusters, they might stock hundreds of thousands of copies of a single title."

"The change may also impact Costco customers, particularly those who live in areas without a bookstore. And because many books at Costco were impulse buys, some of those sales may not shift over to Amazon or Barnes & Noble. Instead, they might not happen at all."

Online marketplace behemoth eBay said it plans to no longer accept American Express, citing what the company says are "unacceptably high fees." CNBC: It's a notable blow to American Express, whose customers are often the most attractive among merchants and spend the most money per month on their cards. But it's not the first time merchants have voiced opposition to AmEx's business practices by walking away, most notably the warehouse chain Costco nearly a decade ago.

[...] Overland said that eBay customers have become aware of new ways to pay for items, making payments more competitive than ever before, and AmEx was no longer a necessary partner for eBay. eBay has increasingly been offering customers buy now, pay later options on purchases through Apple Pay, PayPal and other companies like Klarna and Affirm as well.

Longtime Slashdot reader MattSparkes shares a report from NewScientist: Quantum computing experts are baffled by the UK government's new export restrictions on the exotic devices (source paywalled), saying they make little sense. [The UK government has set limits on the capabilities of quantum computers that can be exported -- starting with those above 34 qubits, and rising as long as error rates are also higher -- and has declined to explain these limits on the grounds of national security.] The legislation applies to both existing, small quantum computers that are of no practical use and larger computers that don't actually exist, so cannot be exported. Instead, there are fears the limits will restrict sales and add bureaucracy to a new and growing sector. For more context, here's an excerpt from an article published by The Telegraph in March: The technology has been added to a list of "dual use" items that could have military uses maintained by the Export Control Joint Unit, which scrutinizes sales of sensitive goods. A national quantum computer strategy published last year described the technology as being "critically important" for defense and national security and said the UK was in a "global race" to develop it. [...] The changes have been introduced as part of a broader update to export rules agreed by Western allies including the US and major European countries. Several nations with particular expertise on quantum computer technologies have added specific curbs, including France which introduced rules at the start of this month.

Last year, industry body Quantum UK said British companies were concerned about the prospect of further export controls, and that they could even put off US companies seeking to relocate to the UK. Quantum computer exports only previously required licenses in specific cases, such as when they were likely to lead to military use. Oxford Instruments, which makes cooling systems for quantum computers, said last year that sales in China had been hit by increasing curbs. James Lindop of law firm Eversheds Sutherland said: "Semiconductor and quantum technologies -- two areas in which the UK already holds a world-leading position -- are increasingly perceived to be highly strategic and critical to UK national security. This will undoubtedly create an additional compliance burden for businesses active in the development and production of the targeted technologies."

GOG, a Poland-based popular gaming platform, has announced plans to enforce a 200MB limit on cloud save files per game. This move may adversely affect players of open-world titles like Cyberpunk 2077, where save folders can reach several gigabytes. A report adds: The company will begin deleting game saves that exceed the limit on Aug 31. When the deadline rolls around, GOG will delete saves for each game, beginning with the oldest until it's below the 200MB threshold. That means your newest saves will survive.
