And we’re not talking noisy, never-take-out-the-trash bad neighbors. We’re talking has-a-harpoon-gun-and-points-it-at-you bad neighbors. According to a new study in Science, some bacteria hunt nearby bacterial species when they’re hungry. Using a special weapon system called the Type VI Secretion System (T6SS), these bacteria shoot, spill, and then absorb the nutrients from the microbes they harpoon. “The punchline is: When things get tough, you eat your neighbors,” said Glen D’Souza, a study author and an assistant professor at Arizona State University, according to a press release. “We’ve known bacteria kill each other, that’s textbook. But what we’re seeing is that it’s not just important that the bacteria have weapons to kill, but they are controlling when they use those weapons specifically for situations to eat others where they can’t grow themselves.” According to the study authors, the research doesn’t just have implications for bacterial neighborhoods; it also has implications for human health and medicine. By harnessing these bacterial weapons, it may be possible to build better targeted antibiotics, designed to overcome antibiotic resistance. Ruthless Bacteria Use HarpoonsResearchers have long known that some bacteria can be ruthless, using weapons like the T6SS to clear out their competition. A nasty tool, the T6SS is essentially a tiny harpoon gun with a poison-tipped needle. When a bacterium shoots the weapon into another bacterium from a separate species, the needle pierces the microbe without killing it. Then, it injects toxins into the microbe that cause its internal nutrients to spill out.Up until now, researchers thought that this weapon helped bacteria eliminate their competition for space and for food, but after watching bacteria use the T6SS to attack their neighbors when food was scarce, the study authors concluded that these tiny harpooners use the weapon not only to remove rivals, but also to consume their competitors’ leaked nutrients.“Watching these cells in action really drives home how resourceful bacteria can be,” said Astrid Stubbusch, another study author and a researcher who worked on the study while at ETH Zurich, according to the press release. “By slowly releasing nutrients from their neighbors, they maximize their nutrient harvesting when every molecule counts.” Absorbing Food From NeighborsTo show that the bacteria used this system to eat when there was no food around, the study authors compared their attacks in both nutrient-rich and nutrient-poor environments. When supplied with ample resources, the bacteria used their harpoons to kill their neighbors quickly, with the released nutrients leaking out and dissolving immediately. But when resources were few and far between, they used their harpoons to kill their neighbors slowly, with the nutrients seeping out and sticking around. “This difference in dissolution time could mean that the killer cells load their spears with different toxins,” D’Souza said in another press release. While one toxin could eliminate the competition for space and for food when nutrients are available, another could create a food source, allowing bacteria to “absorb as many nutrients as possible” when sustenance is in short supply.Because of all this, this weapon system is more than ruthless; it’s also smart, and important to some species’ survival. When genetically unedited T6SS bacteria were put in an environment without food, they survived on spilled nutrients. But when genetically edited T6SS bacteria were placed in a similar environment, they died, because their ability to find food in their neighbors had been “turned off.”Harnessing Bacterial HarpoonsAccording to the study authors, the T6SS system is widely used by bacteria, both in and outside the lab. “It’s present in many different environments,” D’Souza said in one of the press releases. “It’s operational and happening in nature, from the oceans to the human gut.” The study authors add that their research could change the way we think about bacteria and could help in our fight against antibiotic resistance. In fact, the T6SS could one day serve as a foundation for targeted drug delivery systems, which could mitigate the development of broader bacterial resistance to antibiotics. But before that can happen, however, researchers have to learn more about bacterial harpoons, and about when and how bacteria use them, both to beat and eat their neighbors.Article SourcesOur writers at Discovermagazine.com use peer-reviewed studies and high-quality sources for our articles, and our editors review for scientific accuracy and editorial standards.

PERFORMANCE ART With technical improvements, Pokemon Scarlet & Violet are utterly transformed on Nintendo Switch 2 What a difference a frame rate makes. On more powerful hardware, Pokemon Scarlet & Violet are practically different games Article by Alex Donaldson Assistant Editor Published on June 4, 2025 I can scarcely think of a game as hampered by its performance as the original Nintendo Switch release of Pokemon Scarlet & Violet. I can think of loads of games that perform worse, of course - broken, shattered releases - but I struggle to think of a great game so thoroughly compromised just from how it runs. That was the log behind my 2022 review of the games, where I called the games a “super-effective new vision” for the series but bemoaned how it ran. The game became famous for stop-motion windmills and distant cliffsides that looked like they’d fallen out of a Nintendo 64 game. The truth is, Scarlet & Violet’s brilliant design and peppy attitude deserved better. Now, three years on from release, Scarlet & Violet is about to get better with a Switch 2 update that I’m going to go ahead and call a total I was invited by The Pokemon Company to take an early look at the patched Switch 2 version of the game - which is always a sign of confidence, given I was quite a noisy detractor of the original game’s performance. I’m honestly not sure what to say other than: wow, what a difference. It is absolute night and day stuff. To the sort of people who say that frame rate doesn’t really matter, I challenge them to play Scarlet & Violet on Switch 2 and then go back to the original. I dare you. As friend of the site Joe says in Serebii's video preview embedded below, it ain’t doable. Watch on YouTube With a crisp presentation at a higher resolution and with a frame rate that as far as I can tell sits at a rock solid 60fps for the vast majority of the time, this is a world apart from the stomach-turning rollercoaster highs and lows of the original release. Distant Pokemon and world elements are no longer slideshows - yes, those infamous windmills are fixed! This isn’t just about technical bragging rights. The difference in how this game now runs is profound enough that it changes the flow and feel of the game. Scarlet & Violet were by design the most footloose and expansive Pokemon games of all time, channeling the open world chops of everything from Skyrim to Breath of the Wild into a Pokemon setting and setup. The performance was a drag on that - if the frame rate tanks every time you whip the camera around to see a nearby approaching threat or take in a distant vista, you’re ripped right out of the game. By stabilising everything, the performance is utterly transformed. Aside from the nebulous concept of ‘game feel’ being improved by the technical advancements, there are also real boons in terms of gameplay. Wild Pokemon spawn in and swarm across the rolling fields and the like in greater numbers. The subtle delay that you’d perceive, that hitch when encountering a wild Pokemon, is eliminated. Menus that were sluggish are now snappier and more responsive. Pokemon Box sprite icons now spring to life instantly. These are small quality of life changes that add up to something greater. Perhaps most importantly battles are now less plodding in their pace, which was frequently obliterated by certain move animations could send the frame rate crashing. It has to be said, it’s not all perfect. The level of detail settings remain pretty aggressive - which means as you’re galloping along at a glorious 60 frames atop your trusty Poke-steed, flowers and other micro detail pop in around you. It’s not ideal. Also, to be honest, the game now being technically accomplished does help to expose the art style for what it is - which is in need of a bit of tightening, I feel. The addition of HDR does really help the colorful exuberance of Paldea to shine, though. In all it’s a triumph, anyway. This is the game Scarlet & Violet should’ve been. Moreover, it feels like the most technically accomplished main-line Pokemon game… possibly ever? Certainly of the 3D era. As with 120fps mouselook Metroid, playing 3D Pokemon at 60fps feels like you’re doing something illegal, frankly. But this is now the way to play these excellent games - and with good-performing Pokemon games now on the table, my excitement for this year’s Pokemon Legends Z-A has skyrocketed.

How Will Transportation Work in the Future? A Look at the Rise of Electric Mobility in CitiesSave this picture!Boise, United States. Image via Wikipedia user: Fæ. License under CC0 1.0. Image Author: Alden SkeieFrom greenhouse gas emissions and air pollution to deforestation, one of the leading contributors to global warming today is emissions from the transportation sector. Exploring its origins and evolution, as well as the major challenges it faces, the development of electric mobility in urban environments represents a global transition that requires a coordinated mix of policies and actions to achieve cleaner and more sustainable transportation systems. Designing safe and comfortable infrastructure for walking and cycling, promoting public transit and shared mobility, and designing more efficient streets that include electric vehicles, among other actions, are part of a growing worldwide effort to reduce carbon emissions.Although electric vehicles were invented before gasoline and diesel cars in the first half of the 19th century, they have undergone significant technological advances over the past 20 years, reducing their costs and their environmental impact, and increasing their utility. Around 1834, Thomas Davenport developed the first battery-powered electric vehicle, building a small train on a circular track and inventing the first direct current (DC) electric motor. Although there were numerous innovations in the years that followed, battery limitations were a major obstacle. The zinc consumption of a battery was four times more expensive than the coal consumption of a steam engine, so at that time it competed with the electric motor. Save this picture!By 1898, the first commercially available electric vehicles were operating in London and New York. As Francisco Martín Moreno explains in "Vehículos eléctricos. Historia, estado actual y retos futuros", in the early 1900s, several electric car models emerged, primarily accessible to wealthy consumers and designed for short distances. In contrast, the early gasoline-powered cars introduced in the 1920s were noisy, emitted strong gasoline odors, and were hard to drive due to complex gear systems. However, large quantities of oil were discovered between 1920 and 1930, making gasoline-powered cars cheaper in Texas and other US states. Highways began to be built connecting cities, allowing gasoline-powered vehicles to travel from one city to another, something beyond the reach of electric vehicles due to their short range. Mass production techniques like Henry Ford's assembly line further reduced costs, making gas-powered cars affordable to the middle class. Related Article Gas Stations and Electric Cars: How Do They Change Cities Save this picture!By the late 1920s, gasoline vehicles had overtaken electric vehicles, and electric car production largely ceased in the 1930s. However, as a result of the oil crisis in the 1970s and the Gulf War in the 1990s, along with the emergence of climate change as a priority, there was a renewed interest in electric cars. This resurgence led to new models of electric vehicles—from small cars to buses and even trucks. The energy crisis led to an increase in gasoline prices, and society in advanced countries began to become aware of the effects of greenhouse gas emissions from oil combustion, the greenhouse effect, and climate change. Concern about greenhouse gas emissions and climate change increased as oil prices rose, and society began to recognize and become more aware of the impact of the current transportation model on cities and the urgency of finding more environmentally friendly transportation alternatives.Save this picture!Save this picture!In developed countries during the 20th century, the growth of cities was largely due to private car use, allowing citizens to travel miles and miles daily from home to work. Suburban expansion shifted the cost of commuting to individuals. Some residential areas are developing far from the city center and industrial zones, where a large proportion of the population relies on cars. In 2010, the global population was around 7 billion, and it's expected to reach 10 billion by 2050. The number of vehicles, meanwhile, is projected to grow from 75 million in 2010 to 2.5 billion by 2050. Will there be enough fossil fuels to power this massive fleet? What will be the future of gas stations?Save this picture!To meet the goals of the Paris Climate Agreement and reduce growing air pollution, low- and middle-income countries should join the global transition to zero-emission electric transport. According to data from the International Energy Agency and the European Alternative Fuels Observatory, China led the world in 2024 with over 7 million electric vehicles (including cars and buses) in operation—an increase of over 3 million in just one year. The U.S. ranked second, followed by Germany, which leads in Europe with about 1.3 million EVs. The UK and France round out the top five.Save this picture!To support this transition, the United Nations Environment Programme (UNEP) has launched a global initiative alongside private sector partners, academic institutions, and financial organizations, helping low- and middle-income countries shift to electric mobility. In Latin America, transportation accounts for around one-third of CO₂ emissions. In Africa, Asia, and parts of Latin America, motorcycles and three-wheelers are essential for daily mobility, often covering over 100 km per day. However, these vehicles usually rely on outdated technologies, making them highly polluting and inefficient. Electrifying two- and three-wheelers presents a significant opportunity to reduce both greenhouse gas emissions and air pollution. UNEP is assisting 17 countries in creating national strategies and running pilot projects to introduce these electric vehicles in regions like Africa, Southeast Asia, and Latin America.Save this picture!Given the rapid urbanization in many low- and middle-income countries, mass public transport remains a cornerstone of urban mobility. Cities across Africa, Asia, and Latin America are investing in better transportation systems, including high-capacity bus corridors and Bus Rapid Transit (BRT) systems. Yet, with the average bus lifespan exceeding 12 years, it's essential to avoid locking cities into outdated technologies. Developing policies to support and incentivize the adoption of zero-emission vehicles is essential to achieving the electrification of public transport. The European Commission proposes promoting investment initiatives in charging infrastructure and emissions trading, to be implemented starting in 2026, by putting a carbon price on fossil-fuel vehicles. This measure seeks to boost the use of electric vehicles and the transformation of transport systems. Now, how could charging infrastructure be developed to support a potential massive growth in the electric vehicle fleet? What upgrades and innovations are needed to handle this future demand? What would happen if all transportation suddenly depended on the power grid?Save this picture!Save this picture!The UN emphasizes that using public transportation is critical to curbing climate change. Electrifying buses and trains could cut greenhouse gas emissions by up to two-thirds per passenger per kilometer compared to private vehicles. Still, private cars hold the greatest potential for emission reduction. In 2018, light-duty vehicles were responsible for nearly half of all transport emissions—including those from rail, sea, and air travel. Several major carmakers have announced ambitious plans to release new EV models in the next five years.Save this picture!According to a study by the McKinsey Center for Future Mobility (2019), roughly 60% of global car trips are under 8 kilometers, making them ideal for micromobility solutions. Electromicromobility refers to small, lightweight, and low-speed electric transportation options for short distances, such as electric skateboards, scooters, bikes, mopeds, and quadricycles. From a user perspective, electric vehicles still face hurdles like high costs, limited range, and long charging times. However, their broader societal benefits—particularly emissions reductions—are significant. Therefore, local and national governments are encouraged to implement supportive policies, such as vehicle purchase subsidies, tax breaks, free charging stations, parking benefits, access to city centers, and special electricity rates for nighttime charging, etc.Save this picture!Save this picture!Ultimately, we should ask: What lies ahead for modern transportation? How could new forms of natural, artificial, and collective intelligence be integrated into the design of today's transportation systems to improve resilience to environmental and growth challenges? What partnerships between countries, industries, and organizations are needed to ensure a sustainable and innovative supply of key materials? What will happen to used EV batteries and electronic components? Will be electric mobility in cities the only way to reduce carbon emissions?This article is part of the ArchDaily Topics: What Is Future Intelligence?, proudly presented by Gendo, an AI co-pilot for Architects.

Deal pricing and availability subject to change after time of publication.There’s no shortage of wireless earbuds out there, but if you’re after strong noise cancellation, bass-heavy sound, full iOS compatibility, and a fit that won’t budge during a workout, you should consider the Beats Fit Pro, and this open-box deal on StackSocial drops the price to $99.99 from the usual $199.99. The sale includes all four color options—white, black, gray, and purple.The “open box” tag just means they’ve likely been handled but not used, and they’ve been inspected to make sure they’re still in new condition. They’re rated IPX4 for water resistance, so sweat and light rain aren’t a problem, though the case itself isn’t protected and doesn’t support wireless charging. Battery life is around six hours with ANC on and another 18 to 23 hours from the case, depending on how you use them.Sound-wise, these lean hard into bass, which some folks will love and others might find a bit much. The low end hits especially well at high volumes without distortion, which makes them great for hip-hop, pop or EDM, notes this PCMag review. The downside is that there’s no customizable EQ, so if you’re not into that sculpted sound, you can’t do much about it. The noise cancellation holds up pretty well for things like plane rumbles and low-frequency distractions, but don’t expect total silence in a noisy café (higher-pitched noises still leak through). There’s also a decent Transparency Mode that lets in just enough outside sound for you to cross the street or chat with someone without pulling out an earbud. Android users do get access to most core features through the Beats app, but some perks like automatic switching, hands-free Siri, and Spatial Audio are still iOS-only. Getting all that for half off isn't a bad deal.

Tech Flying motorcycle zooms at 124 mph without touching the ground A jet-powered flying bike that combines speed, agility, and futuristic design Published June 1, 2025 6:00am EDT close Flying motorcycle zooms at 124 mph without touching the ground Soar above traffc in the air with ease. Imagine gliding through city traffic, not stuck in traffic jams on the road, but soaring above them in the air with ease. The Volonaut Airbike, a jet-powered flying bike developed by Polish entrepreneur Tomasz Patan, is turning this vision into reality. With a top speed of 124 mph and a frame that is seven times lighter than a typical motorcycle, this innovative vehicle could change the way we get around in cities, making travel faster and easier. Jet-powered flying bike  (Volonaut)Jet power and featherweight designUnlike many personal flying devices that depend on large, noisy propellers, the Volonaut Airbike uses a jet propulsion system. While the exact technical details have not been disclosed, the Airbike's design emphasizes extreme lightness and agility.CHINESE WEARABLE EVTOL JETPACK MAKES HISTORIC FIRST FLIGHTExtensive use of carbon fiber and 3D-printed parts allows the vehicle to weigh just 86 pounds without a rider. This is approximately seven times lighter than an average motorcycle, which typically weighs around 600 pounds. This featherweight construction makes the Airbike nimble and efficient in the air. Jet-powered flying bike  (Volonaut)Performance and featuresThe Volonaut Airbike can reach speeds of up to 124 miles per hour, making it faster than most motorcycles in traffic. It features a proprietary stabilization system enhanced by a flight computer, which automatically maintains hover and provides ease of control for the rider. This technology allows even those with limited flying experience to handle the bike safely and confidently. The Airbike's open, roofless design offers the rider an unobstructed 360-degree view, creating a sense of complete freedom and immersion in the flying experience. Additionally, the absence of spinning propellers means the Airbike can navigate through tight spaces with greater ease and safety. Jet-powered flying bike  (Volonaut)A real-life flying bike inspired by imaginationThe Volonaut Airbike's sleek, futuristic silhouette and compact size evoke the image of a flying motorcycle that many have dreamed about for years. Its design and performance bring to life a concept often seen in movies and stories about the future of transportation. Volonaut's promotional videos even feature a rider dressed as a Stormtrooper, highlighting the bike's resemblance to the flying vehicles of popular culture. This playful nod underscores the Airbike's blend of cutting-edge technology and imaginative design. Jet-powered flying bike  (Volonaut)Meet the inventor: Tomasz PatanTomasz Patan is a visionary engineer with a talent for creating groundbreaking airborne vehicles. He is best known for the Jetson One, a quad-rotor electric vertical take-off and landing (eVTOL) drone that can carry a human pilot. Building on the success of that project, Patan has now introduced the Volonaut Airbike, a smaller, more agile flying machine that relies on jet propulsion rather than propellers. His work continues to push the boundaries of what personal flight can achieve. Jet-powered flying bike  (Volonaut)What about the cost?When it comes to price, the Volonaut Airbike is still something of a mystery. Patan has not yet revealed an official cost, but if you look at his previous project, the Jetson One drone, which was priced at around $92,000, you can get a rough idea of where the Airbike might land. Given the advanced materials, jet propulsion and sophisticated flight computer involved, it's safe to assume this won't be a budget-friendly ride. However, as with most new technologies, prices often come down over time as production scales up and designs are refined. So, while it might start out as a high-end gadget for early adopters and enthusiasts, there's hope that flying bikes like this could become more accessible in the years ahead.WHAT IS ARTIFICIAL INTELLIGENCE (AI)? Jet-powered flying bike  (Volonaut)What lies ahead for the Volonaut Airbike?Although the Volonaut Airbike has already been demonstrated in flight, many details remain undisclosed. Patan has not yet revealed the exact propulsion technology, pricing or release date, but he has expressed optimism the Airbike will be available to the public in the near future. As development continues, this flying motorcycle could soon become a practical option for urban commuters seeking a faster, more flexible way to travel. Jet-powered flying bike  (Volonaut)Kurt's key takeawaysHonestly, the Volonaut Airbike feels like something we've all dreamed about but never thought we'd actually see. It's exciting to watch this blend of bold engineering and creative design come to life, making personal flight more real than ever before. Sure, it might be a bit pricey at first, but who knows? Maybe in a few years, zipping through the skies on a flying bike will be just as normal as hopping on a motorcycle today.CLICK HERE TO GET THE FOX NEWS APPWould you feel comfortable trading your motorcycle for a flying bike that soars above city traffic?

Cicadas are back at it again in 2025, already emerging in droves to announce the approach of summer with their screeches. If you live in the Eastern U.S., get ready to meet (and hear) Brood XIV (14), this year’s batch of periodical cicadas. Cicadas in Brood XIV have begun to pop up in multiple states, climbing out of the underground holes that they’ve spent the last 17 years in. Now, they’ll dedicate the entire month of June to mating and laying eggs before dying. Learn more about the lives of these noisy insects and what makes Brood XIV so noteworthy. Cicadas From South to NorthPeriodical cicadas consist of seven species, falling under 15 broods that either emerge every 13 or 17 years. They’re not the same as annual cicadas, which arrive every summer in much smaller numbers and don’t have the same synchronized development.Most years, one brood of periodical cicadas makes an appearance above ground. However, 2024 was an extraordinary year for cicadas because two adjacent broods (XIII and XIX) overlapped. The rare double-brood event was a must-see, since the next double-brood won’t occur until 2037 (IX and XIX will emerge together, but they aren’t adjacent). This year’s Brood XIV — a 17-year brood — won’t bring as much cicada chaos as last year, but its range is undoubtedly impressive. Cicadas will appear mostly in the Midwest and South, with a large swath concentrated from southern Ohio, down through Kentucky, and Tennessee. Their prevalence in Kentucky has led some to designate Brood XIV as the “Bourbon Brood”.Cicadas in Brood XIV will also appear as far south as northern Georgia and as far north as Long Island, New York, and Cape Cod, Massachusetts. Brood XIV is notable for being the second largest brood after XIX, a 13-year brood referred to as “The Great Southern Brood." Brood XIV is also considered to be the ancestral group from which all other 17-year broods have been shaped. This brood holds a special place in history, as its forebears were first recorded by the Pilgrims in the Plymouth Colony in 1634. Understanding the Cicada Lifecycle Cicadas in Brood XIV were last seen above ground in 2008; the ones that lived back then laid the eggs that have now become the fully-fledged cicadas emerging this year. The cicada life cycle starts when eggs that are located underground hatch into nymphs, which eat fluid from the roots of trees. The nymphs undergo five juvenile stages over the course of years, molting with each stage. They eventually crawl out of exit tunnels and find a spot to molt one final time, marking the start of adulthood. Once the adult cicadas’ exoskeleton hardens, they then focus on mating. The males climb up trees and produce their shrill songs en masse, using muscles to vibrate a rigid part of their exoskeletons called tymbals. After mating, a female cicada lays upwards of 600 eggs that will hatch after six to ten weeks, long after all of the adults have died. The newborn nymphs will then fall out of trees and burrow underground to begin the cycle anew. The Issue with Stragglers Tracking and mapping periodical cicadas of each brood is an ongoing process that needs updating nearly every year. The majority of broods come out on time, but it turns out that not all cicadas are flawless in their timekeeping.One factor that complicates tracking efforts is the existence of stragglers, cicadas that emerge earlier or later than their brood is supposed to. Stragglers that arrive at the wrong time could potentially mix with separate, adjacent broods, causing gene flow. For example, the concern this year is that previous broods could have stragglers that appear late and intermingle with Brood XIV. These stragglers could come from Brood X, which last emerged 4 years ago (and stragglers tend to emerge 1 or 4 years after their parent brood). There usually aren’t many stragglers for any given year, and they’re often picked out quickly by predators. However, some survive and influence nearby broods that emerge on time, which can throw off the data that scientists collect. Beyond the inevitable racket that they’ll create, cicadas are entirely harmless. They don’t bite or sting, but at the very least, be prepared for a loud month ahead.
