We’d like to help everyone get started with the prototype, so here’s a brief summary of the current controls. Controller support is planned for a future update. Posted by AngryCatStudios on May 28th, 2025 - Basic Design/Concepts Controls Spells can be selected in two ways: Hold the Q key briefly to bring up the spell bar, then use A, S, D to navigate or simply left-click on a spell. Or use F2 for Arcane Bolt, F3 for Arcane Shield, and F4 for Time Wrap directly. 💡 Note: This is the first iteration of the keybindings. Full keyboard/mouse and controller support will improve usability in future versions. ■ Character Attributes You can allocate points under Primary Attributes / Skills on your character screen. For a Mage, we recommend: A. Arcana – Grants +1 HP, +1 Tempo, and +3 Focus per rank B. Finesse – Grants +2 HP, +2 Tempo, and +1 Focus per rank If survivability is a priority, invest in Vigor, which grants +4 HP and +1 Tempo per rank. 🧪 Many items also boost these attributes depending on their rarity and stats. ■ Combat Basics Main rule: If you run out of Tempo, end your turn by pressing ENTER or clicking the End Turn button. Your character can only move or act as long as they have Tempo remaining. 🏃‍♂️ Tip: If you're near an Exit (marked with a green arrow), you can flee to the adjacent map. ■ Spell Usage Arcane Bolt – A magical projectile that can hit enemies even without Line of Sight. → Press F2, or hold Q, navigate with A/S/D → Press Q again to enter targeting mode → Rotate target with A/D, cast with F Arcane Shield – Currently self-cast only. Grants both physical and magical protection. → Use F3 or hold Q, navigate to the spell → Target yourself, confirm with F Time Wrap – A spell with dual-purpose effects: → Cast on enemies to increase their Tempo cost → Cast on yourself to reduce your Tempo cost → Use the same selection method as above ■ Targeting & Hit Chance When targeting (rotating with A/D), a stats window appears next to the enemy. ⚠️ Note: The window disappears if you move the mouse. The percentage displayed indicates your hit chance. ■ Additional Tips Lootables such as equipment and consumables (e.g. potions) are essential. You can use potions before or during combat. You cannot change gear while in combat.

There’s an artist in everyone. Some bring their ideas to life with digital tools, others capture the perfect moment with a camera or love to grab pen and paper to create little doodles or pieces of lettering. And even if you think you’re far from being an artist, well, why not explore it? It might just be hidden somewhere deep inside of you. For more than 14 years already our monthly wallpapers series has been the perfect opportunity to do just that: to break out of your daily routine and get fully immersed in a creative little project. This month is no exception, of course. For this post, artists and designers from across the globe once again put their creative skills to the test and designed beautiful, unique, and inspiring desktop wallpapers to accompany you through the new month. You’ll find their artworks compiled below, along with a selection of June favorites from our wallpapers archives that are just too good to be forgotten. A huge thank-you to everyone who shared their designs with us this time around — you’re smashing! If you, too, would like to get featured in one of our next wallpapers posts, please don’t hesitate to submit your design. We can’t wait to see what you’ll come up with! You can click on every image to see a larger preview. We respect and carefully consider the ideas and motivation behind each and every artist’s work. This is why we give all artists the full freedom to explore their creativity and express emotions and experience through their works. This is also why the themes of the wallpapers weren’t anyhow influenced by us but rather designed from scratch by the artists themselves.

Interviews Love, Death + Robots – Volume 4: Tim Miller (Creator & Director) & Jennifer Yuh Nelson (Supervising Director) By Vincent Frei - 02/06/2025 Earlier this year, Tim Miller spoke to us about his animated anthology Secret Level. Now, he returns to discuss the latest season of Love, Death + Robots. Jennifer Yuh Nelson talked about season two of Love, Death + Robots in 2021. She later worked on The Sea Beast, before returning once again to the anthology universe. What was your overall vision for the fourth season of Love, Death and Robots and how did it evolve from previous seasons? Tim Miller (TM) // We have the same strategy as every volume – we try to pick the best stories we know of and provide a mix that is hopefully appealing to everyone. There are a lot of variables to consider. Including genre, tone, and style of animation, such as stop motion, CG, and 2D. We try not to have two stories that are too similar. For example, if there’s already a military sci-fi story, we avoid selecting another one. We like to mix humor, horror, sci-fi, fantasy, and anything else that we think might be interesting from either a story or animation perspective. How did you approach the balance between experimenting with new styles and maintaining the signature identity of the show? TM // Honestly, we just try and follow our gut. What we think is interesting as filmmakers, animators, and storytellers will also be interesting to the animation community and fans alike. So, we keep an eye out for new voices, filmmakers, and new ways of doing things to keep things interesting. I’m not sure we have an identity of the show. In fact, I think if we did have an identity, it would be that we don’t have an identity… but we try and do whatever we think is interesting. Jennifer Yuh Nelson (JYN) // The fortunate thing about LDR is that the signature itself is experimenting with new styles. The trick is finding new aggressively experimental styles that still communicate to a mass audience. The stories are key to that. If the story is engaging, even to an audience that doesn’t usually gravitate to animation, then you can make it looks as weird as you want. What are some of the key challenges you faced while overseeing this season and how do you tackle them? TM // This season, there was a lot going on in the animation community that created some challenges with getting work done, whether studios were too full or ceased to exist entirely. Everyone struggled with budgets. But I didn’t feel like it was a problem with our show but rather a problem with the entire industry. People were struggling. And then it’s just always difficult when your ambition is high, your budgets are reasonable but still challenging, and you have to wrangle hundreds of people to get on board with your vision. (JYN) // These shows take a long time to make. R&D for a look that doesn’t exist can take a lot of trial and error. For example, Emily Dean, who directed Very Pulse of the Machine last season, did For He Can Creep this season. She had a cool angle of making her episode look like lithography. That was very very hard, but somehow Polygon, the studio that made both shorts, came through with it. And I think it turned out very well. Can you talk about how you selected the different animation studios for this season? What made you decide to work with the studios involved? (JYN) // We’ve been very fortunate to have worked with amazing people and studios these last few seasons, so it made sense to float some stories by them again. But it really comes down to the stories, and how each leans towards a certain technique. For example, How Zeke Found Religion was holding a slot where we wanted something 2D. We went to Titmouse because they were great with pushing the boundaries of 2D animation, and they suggested Diego Porral as a director who could bring a modern edge. How do you ensure each studio’s unique visual style complements the story and tone of each episode? TM // I know this sounds a little mystical and I don’t mean it to be, but I think the story speaks to you about style. Some things just feels right, and you have an innate concept of what would be the best version of the story, whether it’s stop motion, CG, 2D animation, or even live action. When you start thinking about the story in a creative way, a style becomes apparent. Which is not to say there aren’t many ways to do things and tell stories, but we feel a best version becomes clear. (JYN) // We do a lot of research, not just into what the studios have done before, but also into what they wish to do but haven’t had the chance to do. Often it’s just a matter of getting to know them and seeing if they have a philosophy of pushing for experimentation and risk. Then we try to support them as much as possible in their creative R&D. You both directed episodes for this season, what was that experience like? How did it differ from your work as overseeing directors? TM // For me, it’s really just trying to create the best story and I love working with the artists and trying to be open to what everybody brings to the table because everybody wants to do the best possible episode they can. I try and be open to letting people help carry that load. The best thing about being a director is that you get to pick and choose between all the great ideas that everybody has and shape the narrative by getting the benefit of everyone’s expertise and talent. (JYN) // It’s a different mindset. As a Supervising Director, I help. As a Director, I do. On episodes I’m not directing, I am deciphering that director’s ambition and pushing for whatever is required to make that absolutely great. On an episode I’m directing, every choice and image has to go through my brain so it’s more a reflection of my personal taste. Plus I tend to storyboard a lot more on my own episodes since it’s a way for me to communicate to the crew. I storyboard a lot on other episodes, but mainly to help figure out problems here and there. It also doesn’t come out of those director’s budgets so the free storyboarding is often welcomed. How did you choose the episode you worked on yourself and what aspects of it made it resonate with you both? TM // In my case with “The Screaming of the Tyrannosaur,” it was really by default. I had written the episode for Zack Snyder but Zack was too busy, and by that time I’d already fallen in love with the story, so I figured, why not just do it myself? As for “Golgotha,” I always loved the story. It was very efficient and short, which is hard to find in a story – it felt like a full meal. It has a beginning, middle, and end and it resolves in a satisfying way. “Golgotha” had all of that, plus it was funny. (JYN) // Spider Rose was on the story wall since the beginning. It was one of the “special” ones- very hard, ambitious, uncomfortable. Over the seasons we offered it to different directors and they veered away from it for one reason or another. But it glowed with a complexity that’s rare in a short story. I think that’s because it was written as an exploration for a far larger world that Bruce Sterling was developing. For me, it was the raw emotionality that drew me in. It’s how I understand how to communicate any story. And I love the way Spider Rose draws you in with emotion then shivs you with it. Were there any episodes in this season that particularly pushed the boundaries of what you had done before? How did that push happen? TM // I think “How Zeke got Religion” pushed the boundaries of 2D animation. The amount of detail and action that the guys at Titmouse were able to pull off was truly astonishing. Once again, Robert Valley outdid himself with 400 boys. The action scene at the end was one of my favorite pieces of animation in all of Love, Death, and Robots. (JYN) // Golgotha, Tim’s episode is live action, which is a rarity for the show. There was one live action episode in season 1, but none since. It is primarily an animation series, but nowadays, the line is so fuzzy that it seemed to make sense. How do you balance creative freedom with the thematic unity required for a show like Love, Death, and Robots? TM // There isn’t really a thematic unity. We’re just trying to create the best version of each of the episodes. They don’t tie into each other, they don’t relate to each other, they aren’t supposed to be about either Love, Death or Robots – the title is a meant to be a “catchall” that could hold ANY story or visual art we thought might be cool. Hopefully, the overall assemblage feels like a balanced meal with a little bit of something for everybody. But thematically speaking, again, I think our theme is that there is no theme. (JYN) // We try to set the foundation with a good story, based off the many short stories Tim has read over the years. Then the HOW of what that story becomes is the wooly Wild West. The directors and studios are fully encouraged to push all the boundaries of how to make these as innovative, impractical, and beautiful as they want. And, since each short is under 15 minutes, the studios we choose can be as experimental and scrappy as each story demands. Looking at the overall direction of the season, was there any unexpected moments or surprises that stood out to you during production? TM // Yeah, I think the color palette for “Zeke” was a shock to me in a wonderful way because it was completely unexpected and nothing I would ever do as a director but boy did I love it. And I think that “Can’t Stop” was an interesting addition. We wanted to do a music video from volume 1 onward, and this was the moment that we took to do it. I think it’s the greatest concert video ever made. (JYN) // Why do we have so many cats and babies? I’ve no idea. But when we saw the first giant baby shots in 400 Boys, it was a rare joy. They walk like babies, real babies. And somehow that was both accurate and terrifying. Looking forward, where do you see the show heading in future seasons, are there any new themes or concepts you’d love to explore? TM // So many directors in the industry have asked if they could play in our sandbox, and I would like to expand our reach to get some established names. Not that we don’t want new talent – we will always want that – but it would be great to have some really fantastic directors who have accomplished big movies come and play with our stories. I also think there’s a version where we bring in some content that may have existed in other mediums like comic books and perhaps tell some larger stories that take more than one episode to tell. Truthfully, I’ve already got a some really interesting stories picked out for the next few seasons, — of course those will change as the show evolves, but they’re fascinating stories that explore the whole arc of history… past, present, and future and some of the big challenges that humanity is facing today. I’d be lying if I didn’t mention that many of them explore the future of what mankind will become with the advent of AI and how artificial intelligence and humanity’s future intersect. (JYN) // Often themes only show up afterwards. There is a bit of a “herding cats” energy to the show that promises surprises in the production process. But the point of a show like this is that it is surprising. It has its own energy, and sometimes we just have to listen to it rather than dictate. If you had the opportunity to create any kind of story for Love, Death, and Robots, what would your dream narrative and what type of animation style would you envision for it? TM // Well, I have to say that I love high-end 3D animation, and that’s what Blur does for a reason. And secondly, I’d like to do a kind of story that could be live action and has some vast scope to it, but we choose to do it in animation because we get more value from using the techniques that animation brings. We can tell a bigger story, with more scope, and more action than we would using any other methodology…. and it competes favorably with live action in terms of the kind of audience that comes to watch it. Not just fans of animation, but fans of good cinema. (JYN) // I’d love to see an anime episode, like a Tsutomu Nihei fight scene, or something by Katsuhiro Otomo. A big thanks for your time.

This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology. The Trump administration has shut down more than 100 climate studies The Trump administration has terminated National Science Foundation grants for more than 100 research projects related to climate change, according to an MIT Technology Review analysis of a database that tracks such cuts. The move will cut off what’s likely to amount to tens of millions of dollars for studies that were previously approved and, in most cases, already in the works. Many believe the administration’s broader motivation is to undermine the power of the university system and prevent research findings that cut against its politics.

Best of the rest Research roundup: 7 stories we almost missed Also: drumming chimpanzees, picking styles of two jazz greats, and an ancient underground city's soundscape Jennifer Ouellette – May 31, 2025 5:37 pm | 4 Time lapse photos show a new ping-pong-playing robot performing a top spin.

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.

On June 5, after years of rumors and anticipation, Nintendo will finally launch the Nintendo Switch 2 worldwide. Preorders are already mostly sold out with millions of gamers anxiously awaiting Mario Kart World Tour and new on-the-go ports of Street Fighter 6 and Cyberpunk 2077. Of course Nintendo is no stranger to the hardware business, launching more than a dozen consoles and portables since the Nintendo Entertainment System (NES). And there have been many ups and downs over the last four decades. When considering which Nintendo system actually had the best launch, we looked at the quality and quantity of games at release, price, as well as the overall impressiveness of the hardware at launch. This retrospective also considers only the North American launches of each system. With that in mind, this is the definitive ranking of all of Nintendo’s console and portable launches since the NES gave the world a red-capped Italian plumber!  13. Virtual Boy Since entering the video game market in the 1970s, Nintendo has rarely encountered a massive failure, but it’s hard to see the Virtual Boy as anything but a colossal misstep, albeit an ambitious one. A home VR system in the mid-‘90s was literally decades ahead of its time, but nothing about it was really consumer friendly. Despite being marketed as a Game Boy successor, the Virtual Boy wasn’t really portable, and at home, it required a table to play. And while the black and white monochrome screen was fine for the original Game Boy, the Virtual Boy’s red and black monochrome display was known to just cause headaches. As for the launch games, they were aggressively… okay? Mario’s Tennis is a perfectly competent, if barebones, tennis game. Meanwhile Teleroboxer was an interesting, just not terribly compelling Punch-Out!! successor. But even if the games were decent, the controller, a god-awful monstrosity mixing the worst aspects of the SNES and N64 controllers, didn’t do these titles any favors. The launch price, equivalent to around $370 USD in 2025 dollars, was the final nail in the Virtual Boy’s coffin, and Nintendo quietly discontinued the console a year after release. 12. Wii U The Wii U is Nintendo’s worst selling console by a large margin, and the problems really were evident from the beginning. The tablet controller was an interesting idea but just not as engaging or innovative as the Wii’s motion controls. Nintendo really banked on Nintendo Land showcasing what the system could do and banked on it being their next Wii Sports, but it ended up just showing how limited the new console really was. And while Mario games have historically been system sellers, New Super Mario Bros. U was largely a rehash of its Wii predecessor, just with HD graphics. It’s a fine platformer, but a surprisingly average Mario game. Beyond that, the launch lineup was largely made up of third party ports, some of which had been available on other consoles for years at that point. It’s easy to see why so many people were confused about whether the Wii U was a new console or an upgrade of the Wii, and why so many of those who understood what it was ended up skipping it, even if the $300 launch price was competitive. 11. Game Boy Color If we were looking at the entire history of Nintendo consoles, the Game Boy Color would certainly rank higher, but Nintendo just didn’t put much effort into its launch, likely because Nintendo absolutely dominated the handheld gaming market at the time. They didn’t have to work very hard to sell this thing. They knew the players would show up. The highlight of the Game Boy Color’s launch in 1998 was Game & Watch Gallery 2, a color collection of the old handheld titles Nintendo made in the ‘80s. It actually was a very good showcase of the GBC’s better color graphics, but it wasn’t the type of game that had much staying power. The other launch titles, Pocket Bomberman, Centipede, and Tetris DX, a colorized version of the original Game Boy’s Tetris launch title, were similarly serviceable but largely forgettable, because seriously, who was dying to play a colorized version of Game Boy Tetris at that point? But at $79.95, the launch price was right, and the GBC quickly built an impressive library of exclusives. 10. Nintendo 3DS When the 3DS was first revealed in 2010, its glasses-free stereoscopic 3D generated an immense amount of buzz. Sadly, a botched launch promptly killed a lot of that momentum. Nintendo’s first party offerings were all oddly disappointing. Pilotwings had been a solid launch series in the past, but Pilotwings Resort lacked a lot of content compared to its predecessors. Steel Diver was an interesting submarine sim that just didn’t quite click. And Nintendogs + Cats, well… it was more Nintendogs for whatever that’s worth. The launch lineup wasn’t all disappointments, however. Street Fighter IV 3D Edition and Rayman 3D were excellent ports of console games, and Tom Clancy’s Ghost Recon: Shadow Wars remains an underrated gem of a tactics game. But arguably the biggest knock against the 3DS was its price. The handheld launched at $250, a price that many gamers balked at. Nintendo was forced to cut the price to $170 just a few months later. Early adopters were compensated with a collection of 20 NES and GBA games, but so many unnecessary missteps left a bad taste in the mouths of many Nintendo fans, and it seems like the 3DS never quite reached its full potential. 9. Nintendo 64 I remember first playing Super Mario 64 in a Toys ‘R Us in 1996 before the U.S. launch and being absolutely blown away. I had never used an analog controller before that let me control how fast or slow my character on screen moved. There had been plenty of 3D platformers prior to that point, but Mario’s first 3D outing truly felt like a giant leap forward for gaming thanks to its silky smooth controls and innovative open world gameplay. Join our mailing list Get the best of Den of Geek delivered right to your inbox! The problem with N64’s launch is that there just wasn’t much else to it. It only launched in the U.S. with Super Mario 64 and Pilotwings 64, which was another excellent showcase for what the console could do, but once you played through those games, new releases were sparse, and expensive, an issue that would continue to plague the console for its entire lifespan. The N64 certainly had quality games, it just could never get much quantity. And while the $250 launch price was reasonable, it was only $50 cheaper than a PlayStation at the time, and given that the PS1 had a much larger library, and its games tended to be cheaper, it’s easy to see why Sony’s console outsold Nintendo’s by a large margin in the late ‘90s. 8. Nintendo DS Nintendo didn’t really seem to know what the DS was supposed to be at first. Seemingly rushed to market in late 2004 to get ahead of the imminent Sony PSP launch, the DS was initially marketed as a “third pillar” system that would sit on shelves alongside the GameCube and Game Boy Advance, though it quickly elbowed the GBA out of the handheld space.  That wasn’t exactly thanks to a great launch lineup though. Super Mario 64 DSFeel the Magic: XY/XX was a weird and wonderful minigame showcase of the handheld’s new features, but it had little mass market appeal. And while games like Madden NFL 2005, Spider-Man 2, and Urbz: Sims in the City were all perfectly serviceable, none of them were on par with their console counterparts. But at $150, the DS was $100 cheaper than the PSP, and that easily helped it become a bestseller.  7. Nintendo Switch  In 2025 the Switch is an undisputed massive success, but its launch in 2017 was very much a mixed bag. First the good: the hardware, though underpowered compared to competitors, is fantastic. Being able to seamlessly switch between playing games on a TV and on the go is a wonderful innovation. The Switch feels great in your hands, and the Joy-Cons still offer some of the best feedback of any controller on the market. It was clear that the system had massive potential from the start, and the $300 launch price undercut both Sony and Microsoft. But the launch lineup was the definition of a one trick pony. Yes, The Legend of Zelda: The Breath of the Wild was an instant classic and absolutely deserves to be in the conversation of the greatest games of all time. But beyond that, how many people even remember the Switch’s other launch games? 1-2 Switch is a lame minigame collection. Super Bomberman R had potential as a launch exclusive, but turned out to be a middling entry in the long running franchise. And ports of Just Dance 2017 and Skylanders: Imaginators weren’t exactly moving systems. Still, the success of the Nintendo Switch makes a really good case that all a console needs to be successful is a great design and one killer app. 6. Game Boy When it launched in 1989, the Game Boy was woefully underpowered and lacked the color screen of competitors like the Sega Game Gear and Atari Lynx. It didn’t really matter though. First Nintendo understood that less power meant longer battery life, which is still about the most important feature for portable gaming. More importantly, the Game Boy had a secret weapon: Tetris.  The classic puzzler was a pack-in title for the Game Boy at launch, the equivalent of giving the first hit away for free to get gamers hooked. At $89.99, the launch bundle was an absolute steal. Along with Tetris, Super Mario Land was a quirky and unique take on the Mario series that was well worth checking out, while ports of Tennis and Baseball from the NES library kept people hooked as the Game Boy gained momentum.  5. GameCube The GameCube launch is both better and worse than you remember it. While the console was kind of knocked for not having any truly great exclusives at launch, the exclusives that were released have actually aged rather well. This was a system where you could pick up Luigi’s Mansion, Wave Race: Blue Storm, Star Wars Rogue Squadron II: Rogue Leader, and Super Monkey Ball at launch, all fantastic titles that weren’t available anywhere else. And while it launched three days after the original Xbox, it was also $100 cheaper. Admittedly, the third-party offerings were a bit slim, but Tony Hawk’s Pro Skater 3Crazy Taxi with the all important arcade soundtrack that’d been missing from more recent releases. But those ports also showed off the GameCube’s biggest weakness: there was really nothing different about these versions if you already owned them elsewhere. It’s not surprising then that after this generation, Nintendo started looking toward new gimmicks to sell consoles instead of just pushing graphics technology to its limits. 4. SNES The SNES didn’t launch with a ton of games, but there wasn’t a stinker in the bunch. Of course there was Super Mario World, still arguably the best Mario game ever made. Not only is the design of that game timeless, but the huge graphical upgrade over anything the NES could do quickly justified the upgrade to a new console. Pilotwings and F-Zero, with their revolutionary use of Mode 7 further showed off the power of the system. The $199 launch price (equivalent to around $460 today) was high for the time, but the launch lineup was so good, the price was kind of justified. Even the two games pulling up the rear, Gradius III and an SNES-exclusive version of SimCity were excellent titles worth picking up. But what’s really underrated about the SNES is how much of an improvement the controller was. It was much more ergonomic than the hard rectangle shape of the NES controller, and the addition of X and Y and shoulder buttons made it clear from the get-go that this console was going to open up a lot of new gameplay styles. 3. Game Boy Advance The Game Boy Advance had an all too brief time as Nintendo’s premiere handheld before the DS took the spotlight, but it built an impressive library during its time starting with the launch. The $100 launch price is quite possibly the best of any piece of Nintendo hardware. And the portable had a solid one, two punch out of the gate with F-Zero: Maximum Velocity, an excellent successor to the SNES title, and Super Mario Advance, a full-fledged remake of Super Mario Bros. 2 that remains the best way to experience this classic.  The 15 other titles available at launch included solid ports of games like Rayman and ChuChuRocket!, with the portability of the GBA version arguably making it more preferable to play than its bigger brother on Dreamcast. But for many, the real star of the launch was Tony Hawk’s Pro Skater 2, a technically impressive port that somehow managed to squeeze all of the gameplay of the console version into an isometric view. Before release, many were touting that the GBA was the equivalent of a handheld SNES. These early games showed that it could actually be even better than that. 2. NES By the mid-1980s, console gaming was essentially dead in North America. Atari had killed the market, flooding it with low quality games. It would take an impressive new console, genius marketing, and just a little bit of luck to bring home gaming back from the brink. The NES succeeded at a tough time for video games by trying not to be just another console. It was more of a toy, or “entertainment system,” sold alongside a Zapper light gun and R.O.B., a robot accessory. Gimmicky? Sure, but that was just the opening salvo in Nintendo’s strategy, the Trojan horse to bring consoles back into the living room. Of course, the games needed to be good for the NES to succeed, and Nintendo had that down pat, launching with 17 titles, including Super Mario Bros., Excitebike, Duck Hunt, and Ice Climbers, titles that are iconic to this day. Other titles like Baseball, Tennis, and Pinball were more perfunctory, but good enough to gain the public’s attention and prove that video games weren’t just a fad. Admittedly, the $200 launch price (equivalent to nearly $600 in today’s dollars) was high, though historically similar to many other launch prices for new consoles, and that price point clearly didn’t do much to dissuade prospective buyers. 1. Wii  Twenty years after the NES brought consoles back from the brink, Nintendo’s home console business found itself in a tough spot. Despite good reviews and a respectable library of games, the GameCube had just taken third place in a three-way fight. Clearly, just trying to build the most powerful console wasn’t the key to success. So as Sony and Microsoft turned to HD gaming, Nintendo released a console just slightly more powerful than its predecessor, but with the benefit of motion controls thanks to the Wii-mote. It sounded kinda nuts. Then people played Wii Sports and were immediately hooked. The game was a phenomenon. Not just hardcore gamers wanted to play it, but parents, and even grandparents. The Wii truly brought console gaming to the masses in a way that had previously been unthinkable thanks to an innovative new controller. Oh, and for the hardcore gamers, a little title by the name of The Legend of Zelda: Twilight PrincessExcite TruckTrauma Center: Second Opinion were more than enough to keep the console flying off shelves for years after release, especially because the older technology meant it could be sold substantially cheaper than either the Xbox 360 or the PS3.

What’s a company to do when it faces a multitude of existential crises and seems unable to regain control of the media message? It throws a few dead cats on the table to distract everybody. This aeons-old approach to public relations has recently been rechristened as “flooding the zone” — and it is what I think Apple is doing as news surfaces that it plans to announce a change to the way it names its operating systems in June at its big developer event, WWDC. That means we won’t ever see iOS 19 but will see iOS 26 instead. It also means: A new Apple OS order iPadOS 26 macOS 26 tvOS 26 visionOS 26 watchOS 26 homeOS 26 You can see the pattern, I hope. The 26 refers to the main year in which an operating system exists, which is a little confusing, as it means we need to look forward to iOS 27 (et al.) in 2026.  I don’t think there’s anything particularly contentious about this change: it’s great for me, as it makes it far less likely I’ll use an incorrect OS version number in my work. But for Apple it’s led to a tidal wave of reports around the decision, and while not all of those are positively spun, the fact that the yarns are being worked at all restores some of Apple’s control over the narrative. Existential threats That’s a degree of media management the company needs, given that almost every other story being written about it at this time involves tariffs, regulation, or its problems with artificial intelligence. Even its bigger stories that should have been good news are delivering unexpected results — for example, what should be seen as huge success in pivoting its manufacturing to India is being seen through the lens of nativist US regulation and tariffs.  Also in politics, Europe’s regulators seem to want to turn Apple regulation into a weapon for use in negotiations over US trade. And in the background, the company’s former Chief Designer Jony Ive’s move to get to work on new devices with OpenAI raises all the ghosts of Expos past. What’s Apple to do? Well, right now it can’t ask Siri for comfort, but maybe that will change next year — and we don’t want people paying too much attention to AI, do we? Apple certainly doesn’t seem to want to discuss any of these challenges too much. The decision by Apple executives not to take part in John Gruber’s traditional WWDC ‘talk show’ represents a company whose leaders feel the need to manage the messaging. Apple has participated in these conversations for a decade, so the change is noteworthy. Waiting for the sun (in the Solarium) That Apple chooses these moments just before WWDC to use its official unofficial news and speculation reporters at Bloomberg to share news about the future of its operating system names represents something similar. First, it gets people talking about something else in the here and now. Second, it begins to set relatively low expectations for Apple’s big developer event. The operating systems will get a facelift (Solarium) designed to make them all work a little more similarly, the iPad will gain tools to make it more Mac-like, and Apple will adopt a new nomenclature culture for its operating system names. What is Solarium? This is a UI update that changes the look of icons, menus, windows, buttons, and more. The idea is to deliver a consistent visual interface across all the devices, intentionally a little translucent like sitting in a glass-walled room dappled by sunlight. Which sounds nice, and probably also means rounder icons, floating controls, spatial depth, and visual cues strongly reminiscent of visionOS 1.0.  Prepare for more shocks Will any of this be enough for Apple to regain control of the narrative? I don’t think so. There’s an outside possibility that Apple will introduce exciting digital health tools and maybe other services that provoke deep interest. But, assuming these do not transpire and Solarium is the hot spot for WWDC, then I strongly suspect Apple will play for time (and control of the media narrative) by throwing a few more dead cats into the ring — at least until Siri is at last capable of telling it when to stop.  You can follow me on social media!

Male fertility rates have been plummeting over the past half-century. An analysis from 1992 noted a steady decrease in sperm counts and quality since the 1940s. A more recent study found that male infertility rates increased nearly 80% from 1990 to 2019. The reasons driving this trend remain a mystery, but frequently cited culprits include obesity, poor diet, and environmental toxins. Infectious diseases such as gonorrhea or chlamydia are often overlooked factors that affect fertility in men. Accumulating evidence suggests that a common single-celled parasite called Toxoplasma gondii may also be a contributor: An April 2025 study showed for the first time that “human sperm lose their heads upon direct contact” with the parasite. I am a microbiologist, and my lab studies Toxoplasma. This new study bolsters emerging findings that underscore the importance of preventing this parasitic infection. The many ways you can get toxoplasmosis Infected cats defecate Toxoplasma eggs into the litter box, garden or other places in the environment where they can be picked up by humans or other animals. Water, shellfish and unwashed fruits and vegetables can also harbor infectious parasite eggs. In addition to eggs, tissue cysts present in the meat of warm-blooded animals can spread toxoplasmosis as well if they are not destroyed by cooking to proper temperature. While most hosts of the parasite can control the initial infection with few if any symptoms, Toxoplasma remains in the body for life as dormant cysts in brain, heart and muscle tissue. These cysts can reactivate and cause additional episodes of severe illness that damage critical organ systems. Between 30% and 50% of the world’s population is permanently infected with Toxoplasma due to the many ways the parasite can spread. Toxoplasma can target male reproductive organs Upon infection, Toxoplasma spreads to virtually every organ and skeletal muscle. Evidence that Toxoplasma can also target human male reproductive organs first surfaced during the height of the AIDS pandemic in the 1980s, when some patients presented with the parasitic infection in their testes. While immunocompromised patients are most at risk for testicular toxoplasmosis, it can also occur in otherwise healthy individuals. Imaging studies of infected mice confirm that Toxoplasma parasites quickly travel to the testes in addition to the brain and eyes within days of infection. Toxoplasma cysts floating in cat feces. DPDx Image Library/CDC In 2017, my colleagues and I found that Toxoplasma can also form cysts in mouse prostates. Researchers have also observed these parasites in the ejaculate of many animals, including human semen, raising the possibility of sexual transmission. Knowing that Toxoplasma can reside in male reproductive organs has prompted analyses of fertility in infected men. A small 2021 study in Prague of 163 men infected with Toxoplasma found that over 86% had semen anomalies. A 2002 study in China found that infertile couples are more likely to have a Toxoplasma infection than fertile couples, 34.83% versus 12.11%. A 2005 study in China also found that sterile men are more likely to test positive for Toxoplasma than fertile men. Not all studies, however, produce a link between toxoplasmosis and sperm quality. Toxoplasma can directly damage human sperm Toxoplasmosis in animals mirrors infection in humans, which allows researchers to address questions that are not easy to examine in people. Testicular function and sperm production are sharply diminished in Toxoplasma-infected mice, rats and rams. Infected mice have significantly lower sperm counts and a higher proportion of abnormally shaped sperm. In that April 2025 study, researchers from Germany, Uruguay, and Chile observed that Toxoplasma can reach the testes and epididymis, the tube where sperm mature and are stored, two days after infection in mice. This finding prompted the team to test what happens when the parasite comes into direct contact with human sperm in a test tube. After only five minutes of exposure to the parasite, 22.4% of sperm cells were beheaded. The number of decapitated sperm increased the longer they interacted with the parasites. Sperm cells that maintained their head were often twisted and misshapen. Some sperm cells had holes in their head, suggesting the parasites were trying to invade them as it would any other type of cell in the organs it infiltrates. In addition to direct contact, Toxoplasma may also damage sperm because the infection promotes chronic inflammation. Inflammatory conditions in the male reproductive tract are harmful to sperm production and function. The researchers speculate that the harmful effects Toxoplasma may have on sperm could be contributing to large global declines in male fertility over the past decades. Sperm exposed to Toxoplasma.

Rojas-Barón et al/The FEBS Journal, CC BY-SA Preventing toxoplasmosis The evidence that Toxoplasma can infiltrate male reproductive organs in animals is compelling, but whether this produces health issues in people remains unclear. Testicular toxoplasmosis shows that parasites can invade human testes, but symptomatic disease is very rare. Studies to date that show defects in the sperm of infected men are too small to draw firm conclusions at this time. Additionally, some reports suggest that rates of toxoplasmosis in high-income countries have not been increasing over the past few decades while male infertility was rising, so it’s likely to only be one part of the puzzle. Regardless of this parasite’s potential effect on fertility, it is wise to avoid Toxoplasma. An infection can cause miscarriage or birth defects if someone acquires it for the first time during pregnancy, and it can be life-threatening for immunocompromised people. Toxoplasma is also the leading cause of death from foodborne illness in the United States. Taking proper care of your cat, promptly cleaning the litter box and thoroughly washing your hands after can help reduce your exposure to Toxoplasma. You can also protect yourself from this parasite by washing fruits and vegetables, cooking meat to proper temperatures before consuming and avoiding raw shellfish, raw water and raw milk.
