Billionaire Elon Musk has countered president Donald Trump's threat to "terminate Elon’s Governmental Subsidies and Contracts," in spectacular fashion: by threatening to cut off the United States' access to outer space."In light of the President’s statement about cancellation of my government contracts, SpaceX will begin decommissioning its Dragon spacecraft immediately," Musk tweeted.But it didn't take him long to blink. A few hours later — and after the publication of this story — Musk reversed course, agreeing to "cool off" and saying that "we won't decommission Dragon."That's not surprising. As executives at SpaceX no doubt desperately tried to explain to him after the dustup, the company would be in terrible danger without all the money it gets from NASA.And if Musk were to make good on his threat, the United States' space program could experience a setback of epic proportions. SpaceX's Dragon spacecraft has quickly become the de facto method for NASA astronauts to travel to the International Space Station.In other words, the threat could prevent American astronauts from visiting the space station — especially considering that the only other American option, Boeing's Starliner, is likely still years away from becoming a viable alternative, if ever.It was a significant escalation in a major falling out between the world's most powerful man and its richest one. The pair have been openly feuding about Trump's so-called "big, beautiful bill," culminating in threats and personal attacks.The collateral damage of the feud could be enormous, particularly for the US space program.Ars Technica's Eric Berger suggested that Trump ripping up Musk's government contracts "would both end the International Space Station and simultaneously provide no way to safely deorbit it.""This just gets better and better," Musk replied in a laughing emoji-laden tweet. "Go ahead, make my day…"The news comes after the Trump administration abruptly pulled its nominee for the NASA administrator role, Jared Isaacman.Isaacman, who was hand-picked by Musk, has been to space twice with the help of SpaceX.The news greatly angered Musk, causing him to go on a crusade against Trump's tax bill.Musk's latest threats to decommission SpaceX's Dragon spacecraft could put the Trump administration and NASA in an extremely unfortunate position. Apart from Boeing's much-maligned Starliner, which has yet to complete a successful crewed mission to the ISS, the only alternative to send astronauts to the space station is Russia's Soyuz spacecraft.While the station's days are already numbered — NASA recently awarded SpaceX a contract to decommission the orbital lab in 2030 — continuing operations could prove extremely difficult without Dragon.But whether Musk will make good on his threat remains to be seen, especially considering the billionaire has a lengthy track record of making empty promises.Apart from vowing to decommission Dragon, Musk also attempted to smear Trump's name by arguing that he's "in the Epstein files.""This is the real reason they have not been made public," he tweeted. "Have a nice day, DJT!"Musk is clearly out for blood, even officially calling for Trump to be impeached and replaced by his vice president JD Vance.Who will emerge victorious is anybody's guess. If there's one certainty, it won't be NASA. The agency is expected to be hit by brutal cuts that could lay waste to dozens of space missions.Share This Article

Solo game developer Joyen has shared great news with the community. Loya, an open-world survival crafter with a walking, buildable fortress that they've been working on for the past seven years, has received its first gameplay trailer.Actually, back in 2022, this Unity project had attracted our attention with its procedurally generated bridge and interiors. Fast forward to now, the game has evolved greatly and received a Steam page with a detailed introduction about its gameplay and features. So let's take a closer look. The highlights of Loya include a walking fortress, giant bosses, exploration, defense, and multiplayer. In this game, players must defeat giants to collect their cores. In order to achieve this, you'll need to build and upgrade the walking fortresses and equip them with powerful weapons.  The materials are not easily obtained; there will be fierce battles to get ready for. The vast open world in Loya appears vibrant, allowing you to explore it at your own pace. The walking fortress can not only walk but also fly, allowing you to ascend high into the air and navigate. Also, you can attach towers to it so it can automatically attack the enemies.JoyenIf you're impressed by the gigantic rocky Golem in the trailer, the solo developer has more great news: there will be four such giants, each on a unique biome. Whether you enjoy exploring and battling solo or prefer teaming up with friends, Loya provides the flexibility you need. You can play along with friends or connect to a dedicated server that holds up to 25 players or more. While sharing the new trailer, Joyen also noted that a playtest is underway, allowing testers to experience the complete first biome, which offers approximately 10 to 20 hours of gameplay. Other biomes include a snowy environment and a desert, with the last one to be revealed later. If Loya looks interesting to you, don't hesitate to add the game to your Steam wishlist and follow Joyen on X/Twitter to check out more in-game footage and receive future updates. Join our 80 Level Talent platform and our new Discord server, follow us on Instagram, Twitter, LinkedIn, Telegram, TikTok, and Threads, where we share breakdowns, the latest news, awesome artworks, and more.

IT Pros ‘Extremely Worried’ About Shadow AI: Report By John P. Mello Jr. June 4, 2025 5:00 AM PT ADVERTISEMENT Enterprise IT Lead Generation Services Fuel Your Pipeline. Close More Deals. Our full-service marketing programs deliver sales-ready leads. 100% Satisfaction Guarantee! Learn more. Shadow AI — the use of AI tools under the radar of IT departments — has information technology directors and executives worried, according to a report released Tuesday. The report, based on a survey of 200 IT directors and executives at U.S. enterprise organizations of 1,000 employees or more, found nearly half the IT pros (46%) were “extremely worried” about shadow AI, and almost all of them (90%) were concerned about it from a privacy and security viewpoint. “As our survey found, shadow AI is resulting in palpable, concerning outcomes, with nearly 80% of IT leaders saying it has resulted in negative incidents such as sensitive data leakage to Gen AI tools, false or inaccurate results, and legal risks of using copyrighted information,” said Krishna Subramanian, co-founder of Campbell, Calif.-based Komprise, the unstructured data management company that produced the report. “Alarmingly, 13% say that shadow AI has caused financial or reputational harm to their organizations,” she told TechNewsWorld. Subramanian added that shadow AI poses a much greater problem than shadow IT, which primarily focuses on departmental power users purchasing cloud instances or SaaS tools without obtaining IT approval. “Now we’ve got an unlimited number of employees using tools like ChatGPT or Claude AI to get work done, but not understanding the potential risk they are putting their organizations at by inadvertently submitting company secrets or customer data into the chat prompt,” she explained. “The data risk is large and growing in still unforeseen ways because of the pace of AI development and adoption and the fact that there is a lot we don’t know about how AI works,” she continued. “It is becoming more humanistic all the time and capable of making decisions independently.” Shadow AI Introduces Security Blind Spots Shadow AI is the next step after shadow IT and is a growing risk, noted James McQuiggan, security awareness advocate at KnowBe4, a security awareness training provider in Clearwater, Fla. “Users use AI tools for content, images, or applications and to process sensitive data or company information without proper security checks,” he told TechNewsWorld. “Most organizations will have privacy, compliance, and data protection policies, and shadow AI introduces blind spots in the organization’s data loss prevention.” “The biggest risk with shadow AI is that the AI application has not passed through a security analysis as approved AI tools may have been,” explained Melissa Ruzzi, director of AI at AppOmni, a SaaS security management software company, in San Mateo, Calif. “Some AI applications may be training models using your data, may not adhere to relevant regulations that your company is required to follow, and may not even have the data storage security level you deem necessary to keep your data from being exposed,” she told TechNewsWorld. “Those risks are blind spots of potential security vulnerabilities in shadow AI.” Krishna Vishnubhotla, vice president of product strategy at Zimperium, a mobile security company based in Dallas, noted that shadow AI extends beyond unapproved applications and involves embedded AI components that can process and disseminate sensitive data in unpredictable ways. “Unlike traditional shadow IT, which may be limited to unauthorized software or hardware, shadow AI can run on employee mobile devices outside the organization’s perimeter and control,” he told TechNewsWorld. “This creates new security and compliance risks that are harder to track and mitigate.” Vishnubhotla added that the financial impact of shadow AI varies, but unauthorized AI tools can lead to significant regulatory fines, data breaches, and loss of intellectual property. “Depending on the scale of the agency and the sensitivity of the data exposed, the costs could range from millions to potentially billions in damages due to compliance violations, remediation efforts, and reputational harm,” he said. “Federal agencies handling vast amounts of sensitive or classified information, financial institutions, and health care organizations are particularly vulnerable,” he said. “These sectors collect and analyze vast amounts of high-value data, making AI tools attractive. But without proper vetting, these tools could be easily exploited.” Shadow AI Everywhere and Easy To Use Nicole Carignan, SVP for security and AI strategy at Darktrace, a global cybersecurity AI company, predicts an explosion of tools that utilize AI and generative AI within enterprises and on devices used by employees. “In addition to managing AI tools that are built in-house, security teams will see a surge in the volume of existing tools that have new AI features and capabilities embedded, as well as a rise in shadow AI,” she told TechNewsWorld. “If the surge remains unchecked, this raises serious questions and concerns about data loss prevention, as well as compliance concerns as new regulations start to take effect.” “That will drive an increasing need for AI asset discovery — the ability for companies to identify and track the use of AI systems throughout the enterprise,” she said. “It is imperative that CIOs and CISOs dig deep into new AI security solutions, asking comprehensive questions about data access and visibility.” Shadow AI has become so rampant because it is everywhere and easy to access through free tools, maintained Komprise’s Subramanian. “All you need is a web browser,” she said. “Enterprise users can inadvertently share company code snippets or corporate data when using these Gen AI tools, which could create data leakage.” “These tools are growing and changing exponentially,” she continued. “It’s really hard to keep up. As the IT leader, how do you track this and determine the risk? Managers might be looking the other way because their teams are getting more done. You may need fewer contractors and full-time employees. But I think the risk of the tools is not well understood.” “The low, or in some cases non-existent, learning curve associated with using Gen AI services has led to rapid adoption, regardless of prior experience with these services,” added Satyam Sinha, CEO and co-founder of Acuvity, a provider of runtime Gen AI security and governance solutions, in Sunnyvale, Calif. “Whereas shadow IT focused on addressing a specific challenge for particular employees or departments, shadow AI addresses multiple challenges for multiple employees and departments. Hence, the greater appeal,” he said. “The abundance and rapid development of Gen AI services also means employees can find the right solution [instantly]. Of course, all these traits have direct security implications.” Banning AI Tools Backfires To support innovation while minimizing the threat of shadow AI, enterprises must take a three-pronged approach, asserted Kris Bondi, CEO and co-founder of Mimoto, a threat detection and response company in San Francisco. They must educate employees on the dangers of unsupported, unmonitored AI tools, create company protocols for what is not acceptable use of unauthorized AI tools, and, most importantly, provide AI tools that are sanctioned. “Explaining why one tool is sanctioned and another isn’t greatly increases compliance,” she told TechNewsWorld. “It does not work for a company to have a zero-use mandate. In fact, this results in an increase in stealth use of shadow AI.” In the very near future, more and more applications will be leveraging AI in different forms, so the reality of shadow AI will be present more than ever, added AppOmni’s Ruzzi. “The best strategy here is employee training and AI usage monitoring,” she said. “It will become crucial to have in place a powerful SaaS security tool that can go beyond detecting direct AI usage of chatbots to detect AI usage connected to other applications,” she continued, “allowing for early discovery, proper risk assessment, and containment to minimize possible negative consequences.” “Shadow AI is just the beginning,” KnowBe4’s McQuiggan added. “As more teams use AI, the risks grow.” He recommended that companies start small, identify what’s being used, and build from there. They should also get legal, HR, and compliance involved. “Make AI governance part of your broader security program,” he said. “The sooner you start, the better you can manage what comes next.” John P.

To figure this out, you're going to need to get a pencil and do some back of the envelope calculations.  You're going to need a couple of bits of information.First, you need to know what devices you are going to power. List them all, because forgetting that coffee pot or heated blanket could make the difference between the power station lasting all day, or giving up the ghost on you before the day is over.Specifically, you want to know how much power, in watts, each device draws. This information is usually found on a label on the device. For example, a heater might draw 1,000W, while a CPAP machine might draw 60W. This figure represents the maximum power consumption, and you will find that the power consumption of some devices, such as CPAP machines, fluctuates greatly, while for other devices, like the heater, the power consumption remains quite stable.Next, you need to know how long you plan on running your devices during a day, or between recharges of your power station. Your heater might run for two hours, while the CPAP machine could run for eight hours.Power station capacities are measured in watt-hours (Wh). A device drawing 1,000W running for one hour uses 1,000Wh. Therefore, the same device running for two hours will need 2,000Wh. Heaters are some of the most power-hungry devices that people find themselves needing to run.Similarly, a CPAP machine that uses 60W will consume 60Wh per hour, so running it for eight hours would consume 480Wh.Your total energy usage over 24 hours would then be 2,480Wh.Based on this, you might think that a 2,500Wh capacity power station would be sufficient. However, in reality, nothing is perfect, and there are energy losses in the system. The rule of thumb is to add 20% to your total and then round up to the next highest capacity available. So, you'd be looking at a power station with a capacity of around 3,000Wh to ensure you have enough stored power for the day. Show more How can I make my power station run longer? Simple: Find your biggest power draws and replace them with more energy efficient alternatives. For example, you might find that you can replace that 1,000W heater with a heated throw that only takes 100W to power. That quilt would run for 10 hours on the power that the heater would use in an hour!Another big power hog is incandescent lights. Swapping these out for LEDs will result in huge power savings and dramatically boost your power station's runtime.   Show more What is the difference between a power station and a power bank? The main difference between portable power stations and portable power banks is the amount of power and what they can charge. Power stations have AC outlets and allow you to charge more and bigger devices, including life-saving ones like a CPAP machine, a cooler, or a floodlight for the campsite while going off-grid.Power banks are much smaller and are best for charging devices like phones, headphones, and smartwatches.  Show more Other portable power stations we've tested Further ZDNET Tech Coverage Smartphones Smartwatches Tablets Laptops TVs Other Tech Resources ZDNET Recommends

With Queens of the Dead, Tina Romero, daughter of the legendary filmmaker George A. Romero, is set to make her first directorial outing, premiering the feature at the Tribeca Film Festival June 7. The filmmaker recently spoke to Entertainment Weekly and reflected on her father’s influence. “I am his kid. There’s no denying it. And he has influenced me greatly.” Romero said. Queens of the Dead will feature Easter eggs to honor her father’s legacy. “And this is his monster, this is his genre. I had fun doing my little Romero nods throughout the film, and we have some good ones,” she shared, including appearances by notable figures such as makeup artist and actor Tom Savini and Dawn of the Dead star Gaylen Ross.  “The zombie apocalypse is such a rich sandbox to play in when it comes to social commentary. I can’t be my dad’s daughter without making an attempt at saying something with zombies,” Romero told the magazine. “I did want this to be a film in which I am paying homage to the world and the monster he created, but I’m also introducing my own voice. It’s very much not a film he would make, but it is using his vocabulary and is playing by his rules. As far as the queer element, on one hand, I just feel like the gays need a zombie film. It’s time that we get to have a big gay zombie movie.” “I didn’t want to touch the genre unless it felt authentic to me,” Romero emphasized. Queens of the Dead revolves around a night in the queer party scene when the nightlife vibes at a warehouse drag show get interrupted by the zombie apocalypse. The inspiration came from intense conflict on social media among party promoters during her stint as a DJ. Romero recounted,  “The original promoter posted this manifesto begging the question, ‘When will the queer community stop devouring its own?’ And it hit me like a bolt of lightning. I was like, ‘Oh my God! This would be how I want to explore the zombie genre in this world of queer nightlife.’” The Mandalorian baddie Katy O’Brien plays the fictionalized promoter who leads the film; Romero noted that there’s a special thanks to Tom Cruise in the credits for letting them take the time off their Mission: Impossible shoot to film the horror flick. Romero hopes the film will shine a light on the hunger for more genre films that represent an intersection of gay scream queens with that familiar flair for horror and dark comedy from her father’s roots. The legendary filmmaker didn’t get to see a completed script but mentored his daughter during the development process. Romero shared, “He said, ‘I love it! Run with it. Go for it.’ Unfortunately, he never got to read the completed script because it took me about seven years to get this developed… but I did have this blessing.” Want more io9 news?

After the Nintendo Switch, the Steam Deck might be the most impressive gaming handheld of the last decade. It brings Steam games—most of which were initially designed to run on Windows PCs—to a remarkably designed portable device. The only problem? Battery life can be rough on some games. If you're struggling to stay charged, here are some tips to help you out.When it comes to your Steam Deck's battery life, you're going to notice a lot of variability, even from one game to another. AAA games that rely on high-end GPUs will typically guzzle power. On laptops or desktops, that's usually not as much of a concern, but on the Steam Deck—when those games run at all—they can burn through the battery quickly.So, while we have plenty of tips to get the best battery life, it's important to keep in mind some games will simply burn through your power no matter what. Fortunately, SteamOS is already pretty power efficient (at least compared to other operating systems), and there are several handy tools to help.First, learn what, exactly, is draining your batteryThere are a few common culprits for battery drain in games, and it's helpful to understand them before diving into solutions. This is because what works for one game with minimal performance impact, could make another game unplayable. With that in mind, here are a few key things that drain your battery:Your hardware settings. The display on your Steam Deck is always a pretty big battery drain, and turning down the brightness can help. Wireless radios like wifi or Bluetooth are always sipping power, even if you're not using them, so you can sometimes turn these off if you don't need them.Your refresh rate and FPS. Your Steam Deck has to update the screen dozens of times every second, and for some games it might be way more than necessary. 60 to 90 frames per second might be necessary for a fast-paced game like Doom Eternal, but it's overkill for Stardew Valley.Your processor's TDP. Thermal Design Power (or TDP) is a complicated metric, but it serves as a shorthand for how much power your processor is using. On the Steam Deck, you can limit this directly, which is a blunt way of saving battery, but it can help sometimes.The most useful tool to help you diagnose your biggest battery drains is the Performance Overlay. Press the three-dot menu button while in a game and navigate to the Performance section and you'll see an option to enable this overlay. There are several levels of detail, ranging from a simple frame rate counter, to real-time power consumption and temperature readouts. The Performance tab is also where you'll find several useful features we'll discuss (under Advanced View), so it's good to make friends with this tab.Dive into your game's display settingsWhile the Steam Deck has a lot of useful features for managing battery life, you're still going to find some of your best options in your game's settings. Most games have presets to lower graphics settings with one quick toggle—like switching from Ultra to Medium—and some have even more advanced settings.This is particularly important to keep in mind if you play Steam games on multiple devices. Some games will try to sync settings between them, which can lead to your game rendering at a higher resolution or frame rate than the Steam Deck is even capable of displaying.In general, here are a few settings you should take a look at:Resolution: The Steam Deck has a 1280x800 resolution, so unless you're using an external monitor, there's no reason to set your game to a higher resolution. Most games won't let you go higher anyway, but it's worth it to double check. You can also go lower for some games, if you don't need as much detail.Frame rate: Many games offer the ability to cap how many frames the game generates, even if your display is capable of showing more. This can have a substantial impact on your battery life, especially for games that need to perform a lot of complex calculations (like graphics-heavy shooters) for every new frame.Graphical presets: If your game has a preset slider, try starting on the lowest preset and working your way up to see how the game performs. The Performance Overlay can be a huge help here, to see how much power your system is drawing on different presets. If your eye can't tell the difference, but your battery can, drop the settings.You can play around to find the right balance for you, and it will vary greatly by game. In some games, you might want more graphical detail, but fewer frames per second, while others would benefit from the exact opposite. Try a few options to see what works best.Adjust your refresh rate and FPS in tandem with the Frame Limit sliderAs mentioned above, the number of times your game updates the screen per second can be a huge factor in battery drain. This is affected by both the screen's refresh rate (how many times the display physically updates the pixel you see) and your game's frames per second (or FPS, the number of times the GPU generates a new frame per second). To complicate matters further, your refresh rate can have an effect on your input latency, meaning it's important to strike a delicate balance.To simplify this, the Steam Deck has a slider called Frame Limit that can impose a limit on how many frames your game displays and strike that balance for you. It automatically adjusts your refresh rate to be evenly divisible by the FPS limit, avoiding unnecessary (and asynchronous) refreshes, while still maintaining the highest refresh rate possible to reduce input lag.It's a workaround that's placed somewhat late in the pipeline, and it's sometimes better to adjust your game's settings directly, but it simplifies a complicated process. If you'd rather adjust your display's refresh rate directly, you can toggle Disable Frame Limit and adjust the refresh rate from 45Hz to 90Hz directly. Keep in mind, though, you might still need to adjust some game settings to avoid generating frames your display will just throw out.Put a cap on your Thermal Design Power (TDP), if you mustTweaking your game's graphics settings can adjust your power consumption with scalpel-like precision. By comparison, the TDP limit is a hammer. But even hammers have their uses. By design, the TDP slider on the Steam Deck will put a hard limit on how much power the CPU/GPU can draw from the battery. You can't get much more direct battery savings than that.The problem is that games typically, you know, need power. And even games with really fine-grain settings don't generally ask the user to decide how much electricity to draw. For some, especially graphics-heavy games, putting a hard limit on TDP can cause massive performance drops or even game crashes.Less demanding games, though, can benefit from playing with this setting. A useful rule of thumb is that if the game you're playing is already struggling to maintain a consistent frame rate, try something else before touching TDP. But for games like Stardew Valley, where you're never really concerned with frame rate, you can experiment with lowering the TDP limit to 10W or even 5W to see how well the game performs.Of course, setting a TDP limit only matters if it's below what your game was using in the first place. This is another area where the performance overlay comes in handy. You can get a sense of how much power your system is drawing during your games, and use that to gauge how low you want your TDP limit to be.Don't forget per-game battery setting profilesOn top of all these settings, you can also set game-specific profiles to change your battery settings automatically based on the title you're playing. I can't recommend this feature enough, especially if you tend to play games with very different power demands. Few things are more annoying than forgetting you set a low TDP limit for a simple game, then launching a more demanding game that strains against that limit.To use this, it's one simple toggle on the Performance tab. Enable "Use per-game profile" and the Steam Deck will automatically create a profile for every game you use. You can disable this toggle to switch back to the default, if you ever decide you prefer one consistent profile.Keep in mind the profiles only account for the Steam Deck's settings itself, not any game-specific settings. But it's still a handy tool. It can be overwhelming to keep track of all the different buttons and knobs you can fiddle with to get extra battery life, but the Steam Deck manages to balance a ton of customization options with the simplicity of straight-forward, user-friendly tools so you can game longer.

Tumor Has ItJun 1, 10:00 AM EDT / by Noor Al-Sibai400 Women Are Suing Pfizer Over Birth Control Shot That Allegedly Gave Them Brain TumorsThe pharmaceutical giant allegedly knew about the risks... but didn't warn patients.Jun 1, 10:00 AM EDT / Noor Al-SibaiImage by Beata Zawrzel / NurPhoto via Getty / FuturismRx/MedicinesRecent research has linked Pfizer's widely-used Depo-Provera birth control shot to massively increased risk of developing brain tumors — and hundreds of women are suing the pharmaceutical giant over it.According to a press release filed on behalf of the roughly 400 plaintiffs in the class action suit, the lawsuit claims that Pfizer and other companies that made generic versions of the injectable contraceptive knew of the link between the shot and the dangerous tumors, but didn't properly warn users.The suit follows a study published by the British Medical Journal last year that found that people who took the progestin-based shot for a year or more were up to 5.6 times more likely to develop meningioma, a slow-building brain tumor that forms, per the Cleveland Clinic, on the meninges, or layers of tissue that covers the brain and spinal cord.Though Pfizer attached warning labels about meningioma to Depo-Provera sold in Canada in 2015 and the UK, Europe, and South Africa after the 2024 study was published, no such label was deployed in the United States — a failure which according to the lawsuit is "inconsistent [with] global safety standards."In an interview with the website DrugWatch, one of the suit's plaintiffs, who was identified by the initials TC, said that she had been "told how great Depo-Provera was" and decided to start it after an unplanned pregnancy that occurred when she'd taken the since-discontinued birth control pill Ortho Tri-Cyclen Lo."I thought it would be more reliable and convenient since I wouldn’t have to take it daily," TC told the site, referencing the four annual injections Depo-Provera requires. "I had no idea it would lead to such serious health problems."After being on the contraceptive shot for three years — and experiencing intense headaches, months-long uterine bleeding, and weight gain — the woman finally consulted her doctor and was diagnosed with meningioma. She's since been undergoing treatment and experienced some relief, but even that experience has been "physically and emotionally draining" because she has to get regular MRIs to monitor the tumor, which likely isn't fatal but still greatly affects her quality of life."It’s a constant worry that the tumor might grow," TC said, "and the appointments feel never-ending."That fear was echoed by others who spoke to the Daily Mail about their meningioma diagnoses after taking Depo-Provera. Unlike TC, Andrea Faulks of Alabama hadn't been on the shots for years when she learned of her brain tumors, which caused her years of anguish.Faulks told the British website that she'd begun taking the medication back in 1993, the year after it was approved by the FDA in the United States. She stopped taking it only a few years later, but spent decades having splitting headaches and experiencing dizziness and tremors. After being dismissed by no fewer than six doctors, the woman finally got an MRI last summer and learned that she had a brain tumor — and is now undergoing radiation to shrink it after all this time."I know this is something I'm going to have to live with for the rest of my life, as long as I live," Faulks told the Daily Mail.Currently, the class action case against Pfizer on behalf of women like Faulks and TC is in its earliest stages as attorneys representing those hundreds of women with brain tumors start working to make them whole.Even if they receive adequate payouts, however, that money won't take away their suffering, or give them back the years of their life lost to tumors they should have been warned about.Share This ArticleImage by Beata Zawrzel / NurPhoto via Getty / FuturismRead This Next

In the past, we've featured year-end roundups of cool science stories we (almost) missed. This year, we're experimenting with a monthly collection. May's list includes a nifty experiment to make a predicted effect of special relativity visible; a ping-pong playing robot that can return hits with 88 percent accuracy; and the discovery of the rare genetic mutation that makes orange cats orange, among other highlights. Special relativity made visible Credit: TU Wien Perhaps the most well-known feature of Albert Einstein's special theory of relativity is time dilation and length contraction. In 1959, two physicists predicted another feature of relativistic motion: an object moving near the speed of light should also appear to be rotated. It's not been possible to demonstrate this experimentally, however—until now. Physicists at the Vienna University of Technology figured out how to reproduce this rotational effect in the lab using laser pulses and precision cameras, according to a paper published in the journal Communications Physics. They found their inspiration in art, specifically an earlier collaboration with an artist named Enar de Dios Rodriguez, who collaborated with VUT and the University of Vienna on a project involving ultra-fast photography and slow light. For this latest research, they used objects shaped like a cube and a sphere and moved them around the lab while zapping them with ultrashort laser pulses, recording the flashes with a high-speed camera. Getting the timing just right effectively yields similar results to a light speed of 2 m/s. After photographing the objects many times using this method, the team then combined the still images into a single image. The results: the cube looked twisted and the sphere's North Pole was in a different location—a demonstration of the rotational effect predicted back in 1959.

Chimpanzees are known to "drum" on the roots of trees as a means of communication, often combining that action with what are known as "pant-hoot" vocalizations (see above video). Scientists have found that the chimps' drumming exhibits key elements of musical rhythm much like humans, according to  a paper published in the journal Current Biology—specifically non-random timing and isochrony. And chimps from different geographical regions have different drumming rhythms. Back in 2022, the same team observed that individual chimps had unique styles of "buttress drumming," which served as a kind of communication, letting others in the same group know their identity, location, and activity. This time around they wanted to know if this was also true of chimps living in different groups and whether their drumming was rhythmic in nature. So they collected video footage of the drumming behavior among 11 chimpanzee communities across six populations in East Africa (Uganda) and West Africa (Ivory Coast), amounting to 371 drumming bouts. Their analysis of the drum patterns confirmed their hypothesis. The western chimps drummed in regularly spaced hits, used faster tempos, and started drumming earlier during their pant-hoot vocalizations. Eastern chimps would alternate between shorter and longer spaced hits. Since this kind of rhythmic percussion is one of the earliest evolved forms of human musical expression and is ubiquitous across cultures, findings such as this could shed light on how our love of rhythm evolved.

Distinctive styles of two jazz greats Jazz lovers likely need no introduction to Joe Pass and Wes Montgomery, 20th century guitarists who influenced generations of jazz musicians with their innovative techniques. Montgomery, for instance, didn't use a pick, preferring to pluck the strings with his thumb—a method he developed because he practiced at night after working all day as a machinist and didn't want to wake his children or neighbors. Pass developed his own range of picking techniques, including fingerpicking, hybrid picking, and "flat picking." Chirag Gokani and Preston Wilson, both with Applied Research Laboratories and the University of Texas, Austin, greatly admired both Pass and Montgomery and decided to explore the underlying the acoustics of their distinctive playing, modeling the interactions of the thumb, fingers, and pick with a guitar string. They described their research during a meeting of the Acoustical Society of America in New Orleans, LA. Among their findings: Montgomery achieved his warm tone by playing closer to the bridge and mostly plucking at the string. Pass's rich tone arose from a combination of using a pick and playing closer to the guitar neck. There were also differences in how much a thumb, finger, and pick slip off the string:  use of the thumb (Montgomery) produced more of a "pluck" compared to the pick (Pass), which produced more of a "strike." Gokani and Wilson think their model could be used to synthesize digital guitars with a more realistic sound, as well as helping guitarists better emulate Pass and Montgomery. Sounds of an ancient underground city Credit: Sezin Nas Turkey is home to the underground city Derinkuyu, originally carved out inside soft volcanic rock around the 8th century BCE. It was later expanded to include four main ventilation channels (and some 50,000 smaller shafts) serving seven levels, which could be closed off from the inside with a large rolling stone. The city could hold up to 20,000 people and it  was connected to another underground city, Kaymakli, via tunnels. Derinkuyu helped protect Arab Muslims during the Arab-Byzantine wars, served as a refuge from the Ottomans in the 14th century, and as a haven for Armenians escaping persecution in the early 20th century, among other functions. The tunnels were rediscovered in the 1960s and about half of the city has been open to visitors since 2016. The site is naturally of great archaeological interest, but there has been little to no research on the acoustics of the site, particularly the ventilation channels—one of Derinkuyu's most unique features, according to Sezin Nas, an architectural acoustician at Istanbul Galata University in Turkey.  She gave a talk at a meeting of the Acoustical Society of America in New Orleans, LA, about her work on the site's acoustic environment. Nas analyzed a church, a living area, and a kitchen, measuring sound sources and reverberation patterns, among other factors, to create a 3D virtual soundscape. The hope is that a better understanding of this aspect of Derinkuyu could improve the design of future underground urban spaces—as well as one day using her virtual soundscape to enable visitors to experience the sounds of the city themselves. MIT's latest ping-pong robot Robots playing ping-pong have been a thing since the 1980s, of particular interest to scientists because it requires the robot to combine the slow, precise ability to grasp and pick up objects with dynamic, adaptable locomotion. Such robots need high-speed machine vision, fast motors and actuators, precise control, and the ability to make accurate predictions in real time, not to mention being able to develop a game strategy. More recent designs use AI techniques to allow the robots to "learn" from prior data to improve their performance. MIT researchers have built their own version of a ping-pong playing robot, incorporating a lightweight design and the ability to precisely return shots. They built on prior work developing the Humanoid, a small bipedal two-armed robot—specifically, modifying the Humanoid's arm by adding an extra degree of freedom to the wrist so the robot could control a ping-pong paddle. They tested their robot by mounting it on a ping-pong table and lobbing 150 balls at it from the other side of the table, capturing the action with high-speed cameras. The new bot can execute three different swing types (loop, drive, and chip) and during the trial runs it returned the ball with impressive accuracy across all three types: 88.4 percent, 89.2 percent, and 87.5 percent, respectively. Subsequent tweaks to theirrystem brought the robot's strike speed up to 19 meters per second (about 42 MPH), close to the 12 to 25 meters per second of advanced human players. The addition of control algorithms gave the robot the ability to aim. The robot still has limited mobility and reach because it has to be fixed to the ping-pong table but the MIT researchers plan to rig it to a gantry or wheeled platform in the future to address that shortcoming. Why orange cats are orange Credit: Astropulse/CC BY-SA 3.0 Cat lovers know orange cats are special for more than their unique coloring, but that's the quality that has intrigued scientists for almost a century. Sure, lots of animals have orange, ginger, or yellow hues, like tigers, orangutans, and golden retrievers. But in domestic cats that color is specifically linked to sex. Almost all orange cats are male. Scientists have now identified the genetic mutation responsible and it appears to be unique to cats, according to a paper published in the journal Current Biology. Prior work had narrowed down the region on the X chromosome most likely to contain the relevant mutation. The scientists knew that females usually have just one copy of the mutation and in that case have tortoiseshell (partially orange) coloring, although in rare cases, a female cat will be orange if both X chromosomes have the mutation. Over the last five to ten years, there has been an explosion in genome resources (including complete sequenced genomes) for cats which greatly aided the team's research, along with taking additional DNA samples from cats at spay and neuter clinics. From an initial pool of 51 candidate variants, the scientists narrowed it down to three genes, only one of which was likely to play any role in gene regulation: Arhgap36. It wasn't known to play any role in pigment cells in humans, mice, or non-orange cats. But orange cats are special; their mutation (sex-linked orange) turns on Arhgap36 expression in pigment cells (and only pigment cells), thereby interfering with the molecular pathway that controls coat color in other orange-shaded mammals. The scientists suggest that this is an example of how genes can acquire new functions, thereby enabling species to better adapt and evolve.

Not a Roman "massacre" after all Credit: Martin Smith In 1936, archaeologists excavating the Iron Age hill fort Maiden Castle in the UK unearthed dozens of human skeletons, all showing signs of lethal injuries to the head and upper body—likely inflicted with weaponry. At the time, this was interpreted as evidence of a pitched battle between the Britons of the local Durotriges tribe and invading Romans. The Romans slaughtered the native inhabitants, thereby bringing a sudden violent end to the Iron Age. At least that's the popular narrative that has prevailed ever since in countless popular articles, books, and documentaries. But a paper published in the Oxford Journal of Archaeology calls that narrative into question. Archaeologists at Bournemouth University have re-analyzed those burials, incorporating radiocarbon dating into their efforts. They concluded that those individuals didn't die in a single brutal battle. Rather, it was Britons killing other Britons over multiple generations between the first century BCE and the first century CE—most likely in periodic localized outbursts of violence in the lead-up to the Roman conquest of Britain. It's possible there are still many human remains waiting to be discovered at the site, which could shed further light on what happened at Maiden Castle.
