Navigating the dense urban canyons of cities like San Francisco or New York can be a nightmare for GPS systems. The towering skyscrapers block and reflect satellite signals, leading to location errors of tens of meters. For you and me, that might mean a missed turn. But for an autonomous vehicle or a delivery robot, that level of imprecision is the difference between a successful mission and a costly failure. These machines require pinpoint accuracy to operate safely and efficiently. Addressing this critical challenge, researchers from the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have introduced a groundbreaking new method for visual localization during CVPR 2025 Their new paper, “FG2: Fine-Grained Cross-View Localization by Fine-Grained Feature Matching,” presents a novel AI model that significantly enhances the ability of a ground-level system, like an autonomous car, to determine its exact position and orientation using only a camera and a corresponding aerial (or satellite) image. The new approach has demonstrated a remarkable 28% reduction in mean localization error compared to the previous state-of-the-art on a challenging public dataset. Key Takeaways: Superior Accuracy: The FG2 model reduces the average localization error by a significant 28% on the VIGOR cross-area test set, a challenging benchmark for this task. Human-like Intuition: Instead of relying on abstract descriptors, the model mimics human reasoning by matching fine-grained, semantically consistent features—like curbs, crosswalks, and buildings—between a ground-level photo and an aerial map. Enhanced Interpretability: The method allows researchers to “see” what the AI is “thinking” by visualizing exactly which features in the ground and aerial images are being matched, a major step forward from previous “black box” models. Weakly Supervised Learning: Remarkably, the model learns these complex and consistent feature matches without any direct labels for correspondences. It achieves this using only the final camera pose as a supervisory signal. Challenge: Seeing the World from Two Different Angles The core problem of cross-view localization is the dramatic difference in perspective between a street-level camera and an overhead satellite view. A building facade seen from the ground looks completely different from its rooftop signature in an aerial image. Existing methods have struggled with this. Some create a general “descriptor” for the entire scene, but this is an abstract approach that doesn’t mirror how humans naturally localize themselves by spotting specific landmarks. Other methods transform the ground image into a Bird’s-Eye-View (BEV) but are often limited to the ground plane, ignoring crucial vertical structures like buildings. FG2: Matching Fine-Grained Features The EPFL team’s FG2 method introduces a more intuitive and effective process. It aligns two sets of points: one generated from the ground-level image and another sampled from the aerial map. Here’s a breakdown of their innovative pipeline: Mapping to 3D: The process begins by taking the features from the ground-level image and lifting them into a 3D point cloud centered around the camera. This creates a 3D representation of the immediate environment. Smart Pooling to BEV: This is where the magic happens. Instead of simply flattening the 3D data, the model learns to intelligently select the most important features along the vertical (height) dimension for each point. It essentially asks, “For this spot on the map, is the ground-level road marking more important, or is the edge of that building’s roof the better landmark?” This selection process is crucial, as it allows the model to correctly associate features like building facades with their corresponding rooftops in the aerial view. Feature Matching and Pose Estimation: Once both the ground and aerial views are represented as 2D point planes with rich feature descriptors, the model computes the similarity between them. It then samples a sparse set of the most confident matches and uses a classic geometric algorithm called Procrustes alignment to calculate the precise 3-DoF (x, y, and yaw) pose. Unprecedented Performance and Interpretability The results speak for themselves. On the challenging VIGOR dataset, which includes images from different cities in its cross-area test, FG2 reduced the mean localization error by 28% compared to the previous best method. It also demonstrated superior generalization capabilities on the KITTI dataset, a staple in autonomous driving research. Perhaps more importantly, the FG2 model offers a new level of transparency. By visualizing the matched points, the researchers showed that the model learns semantically consistent correspondences without being explicitly told to. For example, the system correctly matches zebra crossings, road markings, and even building facades in the ground view to their corresponding locations on the aerial map. This interpretability is extremenly valuable for building trust in safety-critical autonomous systems. “A Clearer Path” for Autonomous Navigation The FG2 method represents a significant leap forward in fine-grained visual localization. By developing a model that intelligently selects and matches features in a way that mirrors human intuition, the EPFL researchers have not only shattered previous accuracy records but also made the decision-making process of the AI more interpretable. This work paves the way for more robust and reliable navigation systems for autonomous vehicles, drones, and robots, bringing us one step closer to a future where machines can confidently navigate our world, even when GPS fails them.

Key Takeaways on Ant PoopDo ants poop? Yes. Any creature that eats will poop and ants are no exception. Because ants live in close quarters, they need to protect the colony from their feces so bacteria and fungus doesn't infect their health. This is why they use toilet chambers. Whether they isolate it in a toilet chamber or kick it to the curb, ants don’t keep their waste around. But some ants find a use for that stuff. One such species is the leafcutter ant that takes little clippings of leaves and uses these leaves to grow a very particular fungus that they then eat.Like urban humans, ants live in close quarters. Ant colonies can be home to thousands, even tens of thousands of individuals, depending on the species. And like any creature that eats, ants poop. When you combine close quarters and loads of feces, you have a recipe for disease, says Jessica Ware, curator and division chair of Invertebrate Zoology at the American Museum of Natural History. “Ant poop can harbor bacteria, and because it contains partly undigested food, it can grow bacteria and fungus that could threaten the health of the colony,” Ware says. But ant colonies aren’t seething beds of disease. That’s because ants are scrupulous about hygiene.Ants Do Poop and Ant Toilets Are RealAnt colony underground with ant chambers. (Image Credit: Lidok_L/Shutterstock)To keep themselves and their nests clean, ants have evolved some interesting housekeeping strategies. Some types of ants actually have toilets — or at least something we might call toilets. Their nests are very complicated, with lots of different tunnels and chambers, explains Ware, and one of those chambers is a toilet chamber. Ants don’t visit the toilet when they feel the call of nature. Instead, worker ants who are on latrine duty collect the poop and carry it to the toilet chamber, which is located far away from other parts of the nest. What Does Ant Poop Look Like? This isn’t as messy a chore as it sounds. Like most insects, ants are water-limited, says Ware, so they try to get as much liquid out of their food as possible. This results in small, hard, usually black or brownish pellets of poop. The poop is dry and hard enough so that for ant species that don’t have indoor toilet chambers, the workers can just kick the poop out of the nest.Ants Use Poop as FertilizerWhether they isolate it in a toilet chamber or kick it to the curb, ants don’t keep their waste around. Well, at least most types of ants don’t. Some ants find a use for that stuff. One such species is the leafcutter ant. “They basically take little clippings of leaves and use these leaves to grow a very particular fungus that they then eat,” says Ware. “They don't eat the leaves, they eat the fungus.” And yep, they use their poop to fertilize their crops. “They’re basically gardeners,” Ware says. If you’d like to see leafcutter ants at work in their gardens and you happen to be in the New York City area, drop by the American Museum of Natural History. They have a large colony of fungus-gardening ants on display.Other Insects That Use ToiletsAnts may have toilets, but termites have even wilder ways of dealing with their wastes. Termites and ants might seem similar at first sight, but they aren’t closely related. Ants are more closely related to bees, while termites are more closely related to cockroaches, explains Aram Mikaelyan, an entomologist at North Carolina State University who studies the co-evolution of insects and their gut microbiomes. So ants’ and termites’ styles of social living evolved independently, and their solutions to the waste problem are quite different.“Termites have found a way to not distance themselves from the feces,” says Mikaelyan. “Instead, they use the feces itself as building material.” They’re able to do this because they feed on wood, Mikaelyan explains. When wood passes through the termites’ digestive systems into the poop, it enables a type of bacteria called Actinobacteria. These bacteria are the source of many antibiotics that humans use. (Leafcutter ants also use Actinobacteria to keep their fungus gardens free of parasites.) So that unusual building material acts as a disinfectant. Mikaelyan describes it as “a living disinfectant wall, like a Clorox wall, almost.”Insect HygieneIt may seem surprising that ants and termites are so tidy and concerned with hygiene, but it’s really not uncommon. “Insects in general are cleaner than we think,” says Ware. “We often think of insects as being really gross, but most insects don’t want to lie in their own filth.”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.

As President Donald Trump kicked off a birthday military parade on the streets of Washington, DC, what’s estimated as roughly 2,000 events were held across the US and beyond — protesting Trump and Elon Musk’s evisceration of government services, an unprecedented crackdown by Immigration and Customs Enforcement (ICE), and countless other actions from the administration in its first five months. Held under the title “No Kings” (with, as you’ll see, one conspicuous exception), they’re the latest in several mass protests, following April’s Hands Off events and a wave of Tesla Takedown demonstrations in March.As The Verge’s Tina Nguyen went to downtown DC, we also sent reporters to No Kings demonstrations spanning the country, plus a “No Tyrants” event in the UK. How would they unfold after promises of “very heavy force” against protesters in the capital, after the deployment of thousands of military troops in a move a judge has bluntly called illegal, and after promises to “liberate” the city of Los Angeles from its “burdensome leadership” by local elected officials? What about the overnight killing of a Minnesota Democratic state representative and her husband, and the shooting of a Democratic state senator and his wife?The answer, at the events we attended, was fairly calmly — even against a backdrop of chaos.Downtown Los Angeles, CaliforniaAn inflatable baby Donald Trump, dressed in a diaper, hovered over throngs of people rallying outside of Los Angeles City Hall. Demonstrators outnumbered clumps of California National Guard members in fatigues posted up along sidewalks. “Go home to your families, we don’t need you in our streets,” one young person wearing a long braid down her back tells them while marching past. “Trump come catch these hands foo!” the back of her sign reads. I can’t see what the front says, but I can tell there’s an empty bag of Cheetos pasted to it.The big baby joins the march, floating through the streets of Downtown LA over demonstrators. A flatbed truck rolls ahead of it, the band — maybe LA’s own Ozomatli? — singing “We don’t like Trump” to the tune of “We Want The Funk.” Ducking inside Grand Central Market from the march, I talk to Puck and Twinkle Toes — two demonstrators in line for the public restrooms. Twinkle Toes tells me she’s part of an activist clown collective called Imp and Circumstance, wearing pink and white clown makeup and a striped pink and white bow wrapped around a loose hair bun atop her head. She’s here exercising her right to free speech, she says. Demonstrators in Los Angeles marched alongside an inflatable Donald Trump baby dressed in a diaper.“The more people that are out here, the more we know that this is not okay. That we don’t want an autocrat. We want democracy,” Puck tells me, adding that the Pride March in Hollywood last weekend was “nothing but love and sunshine” despite protests and burning driverless cars making headlines in downtown. “The news tries to make you think all of LA is rioting. It’s not.” Puck says.Back out on the streets, a young man quickly writes “Fuck ICE” on a black wall with white spray paint before a group of older demonstrators wearing floppy hats shushes him away — warning him that tagging will only attract more law enforcement.Further along, another older man with tufts of white hair sticking out under his Lakers cap walks stiffly and slowly along under the summer sun. A Mexican flag draped across his shoulders, he crosses Hope Street. A young man wearing a Nike cap makes his way over to ask if he wants water; the old man accepts a bottle and keeps walking without stopping. The march has looped around downtown, and is coming to an end back at City Hall. As I make my way to my bus stop, a line of police vehicles — sirens blasting — whizzes past me, back toward the crowd still gathering around City Hall.The Los Angeles Police Department issued a dispersal order for parts of downtown Los Angeles later in the afternoon, citing people “throwing rocks, bricks, bottles and other objects.” Law enforcement reportedly cleared crowds using gas, and the LAPD authorized the use of “less lethal” force.— Justine CalmaPortland, OregonFour different “No Kings” protests in the greater Portland area on Saturday drew massive crowds of tens of thousands across the city. Various activists, government officials, and representatives for politicians spoke at the rallies, which also featured music and live performances. (One advertised free drag shows.) Protesters of all ages came with dogs, strollers, flags, banners, and hand-made signs. At the downtown waterfront, some tourist boats appeared to still be departing, but the bike rental stand (which also sells ice cream) was closed for the day with a hand-lettered explanation reading “No crowns, no thrones, no kings” and “Americans against oligarchy.” Women appearing to be organizers passed out free American flags; many attendees came with their own American flags modified to fly upside down. Most protesters brought signs expressing a wide range of sentiments on the theme of “No Kings.” Some signs were surprisingly verbose (“If the founders wanted a unitary executive (a king) we’d all still be British”) while others were more succinct (“Sic semper tyrannis”). Others opted for simple images, such as a picture of a crown crossed out, or — less frequently — a guillotine. Image: Sarah JeongThe waterfront park area was filled with people from the shoreline to the curb of the nearest street, where protesters held up signs to passing cars that honked in approval. The honking of a passing fire truck sent the crowd into an uproarious cheer. Portland is about a thousand miles from the border with Mexico, but the flag of its distant neighbor nation has emerged as protest iconography in solidarity with Los Angeles. The rainbow pride flag was flown as often as the Mexican flag. Military veterans were scattered throughout the crowd, some identifying themselves as having seen action in conflicts spanning from Vietnam to Afghanistan. Emanuel, an Air Force veteran, told me that he had turned out in defense of the constitution and due process, saying, “Nobody has any rights if one person doesn’t have any rights.” Image: Sarah JeongAnger was directed at ICE and the mass deportations all throughout the day, in signage, in chants, and in rally speeches. The previous night, about 150 people protested at a local ICE facility — coincidentally located by the Tesla dealership — a mile south of downtown, near a highway exit. The ICE facility protests, which have been continuous for some days, have been steadily building up. A couple of “No Kings” signs were present on Friday. (The following day, a handful of “Chinga la migra” signs would show up at the “No Kings” protests). Demonstrators stood on the curb urging passing cars to “Honk if you hate fascists,” successfully eliciting car horns every few seconds, including some from a pristine white Tesla. Federal law enforcement in camo and helmets, their faces obscured, maced and shot at protesters with pepper balls, targeting them through the gates and sniping at them from the rooftop of the building. A handful of protesters — many wearing gas masks and respirators — formed phalanx formations in the driveway, wielding umbrellas and handmade shields. On Saturday, a speaker at one of the “No Kings” rallies advertised the occupation of the ICE facility, saying, “We’re a sanctuary city.” The crowd — replete with American flags both upside down and right side up — cheered. — Sarah JeongNew Port Richey, FloridaNearly every intersection on Pasco County’s State Road 54 looks the same: a cross-section of strip malls, each anchored by a Walmart or Target or Publix, surrounded by a mix of restaurants, nail salons, and gas stations. It’s not an environment that is particularly conducive to protests, but hundreds of people turned out in humid, 90-plus degree weather anyway. The overall size of the crowd is hard to determine, but it’s larger than I — and other attendees — anticipated, given the local demographics. (Trump won 61 percent of the vote in Pasco County in 2024.) New Port Richey, FL. Image: Gaby Del ValleEveryone is on the sidewalk; an organizer with a megaphone tells people to use crosswalks if they’re going to attempt to brave the six-lane highway. Two days earlier, Governor Ron DeSantis said Floridians could legally run over protesters on the street if they feel “threatened.” New Port Richey, FL. Image: Gaby Del ValleSo far, most drivers seem friendly. There are lots of supportive honks. One woman rolls down her window and thanks the protesters. “I love you! I wish I could be with you, but I have to work today!” she yells as she drives away. Not everyone is amenable. A man in a MAGA hat marches through the crowd waving a “thin green line” flag and yelling “long live the king!” as people in the crowd call him a traitor. A pickup truck drives by blasting “Ice Ice Baby,” waving another pro-law enforcement flag. The protesters have flags, too: American flags large and small, some upside down; Mexican; Ukrainian; Palestinian; Canadian; different configurations of pride and trans flags. Their signs, like their flags, illustrate their diverse reasons for attending: opposition to Trump’s “big beautiful” funding bill, DOGE’s budget cuts, and ICE arrests; support for immigrants, government workers, and Palestinians. One woman wears an inflatable chicken suit. Her friend pulls an effigy of Trump — dressed to look both like an eighteenth-century monarch, a taco, and a chicken — alongside her.New Port Richey, FL. Image: Gaby Del ValleMost of the demonstrators are on the older side, but there are people of all ages in attendance. “I thought it was going to be maybe 20 people with a couple of signs,” Abby, 24, says, adding that she’s pleasantly surprised at both the turnout and the fact that most of the protesters are of retirement age. Abe, 20, tells me this is his first protest. Holding a sign that says “ICE = GESTAPO,” he tells me he came out to support a friend who is Mexican. Three teenagers walk by with signs expressing support for immigrants: “While Trump destroys America, we built it.” “Trump: 3 felonies. My parents: 0.” As I drive away, I notice nine counter-protesters off to the side, around the corner from the main event. They wave their own flags, but the demonstrators seemingly pay them no mind.— Gaby Del ValleHistoric Filipinotown, Los AngelesWearing a camo baseball cap — “Desert Storm Veteran” emblazoned on the front — Joe Arciaga greets a crowd of about 100 people in Los Angeles’ Historic Filipinotown around 9:00AM.“Good morning everyone, are you ready for some beautiful trouble?” Arciaga says into the megaphone, an American flag bandana wrapped around his wrist. The faces of Filipino labor leaders Philip Vera Cruz and Larry Itliong, who organized farm workers alongside Cesar Chavez, peer over his shoulders from a mural that lines the length of Unidad Park where Arciaga and a group called Lakas Collective helped organize this neighborhood No Kings rally. “I’m a Desert Storm veteran, and I’m a father of three and a grandfather of three, and I want to work for a future where democracy is upheld, due process, civil rights, the preservation of the rule of law — That’s all I want. I’m not a billionaire, I’m just a regular Joe, right?”, he tells The Verge.Joe Arciaga speaks to people at a rally in Historic Filipinotown, Los Angeles. Image: Justine Calma“I am mad as hell,” he says, when I ask him about the Army 250th anniversary parade Donald Trump has organized in Washington, DC coinciding with the president’s birthday. “The guy does not deserve to be honored, he’s a draft dodger, right?” Arciaga says. He’s “livid” that the President and DOGE have fired veterans working for federal agencies and slashed VA staff.Arciaga organizes the crowd into two lines that file out of the park to stand along Beverly Blvd., one of the main drags through LA. Arciaga has deputized a handful of attendees with security or medical experience with whistles to serve as “marshals” tasked with flagging and de-escalating any potentially risky situation that might arise. Johneric Concordia, one of the co-founders of the popular The Park’s Finest barbecue joint in the neighborhood, is MCing out on Beverly Blvd. He and Arciaga direct people onto the sidewalks and off the asphalt as honking cars zip by. In between chants of “No hate! No fear! Immigrants are welcome here!” and rap songs from LA artist Bambu that Concordia plays from a speaker, Concordia hypes up the organizers. “Who’s cool? Joe’s cool?” He spits into the microphone connected to his speaker. “Who’s streets? Our streets!” the crowd cheers. An hour later, a man sitting at a red light in a black Prius rolls down his window. “Go home!” he yells from the intersection. “Take your Mexican flag and go home!”The crowd mostly ignores him. One attendee on the corner holds up his “No Kings” sign to the Prius without turning his head to look at him. A few minutes later, a jogger in a blue t-shirt raises his fist as he passes the crowd. “Fuck yeah guys,” he says to cheers.By 10AM, the neighborhood event is coming to a close. Demonstrators start to trickle away, some fanning out to other rallies planned across LA today. Concordia is heading out too, microphone and speaker still in hand, “If you’re headed to downtown, watch out for suspicious crew cuts!” — Justine CalmaSan Francisco, California1/10Most of the crowd trickled out after 2pm, which was the scheduled end time of the protest, but hundreds stayed in the area. Image: Vjeran PavicLondon, UKLondon’s protest was a little different than most: it was almost entirely bereft of “No Kings” signs, thanks to the fact that about two miles away much larger crowds were gathered to celebrate the official birthday of one King Charles III. “We don’t have anything against King Charles,” Alyssa, a member of organizers Indivisible London, told me. And so, “out of respect for our host country as immigrants,” they instead set up shop in front of the US embassy with a tweaked message: “No kings, no crowns” became “no tyrants, no clowns.” London, UK. Image: Dominic PrestonOf the hundreds gathered, not everyone got the memo, with a few painted signs decrying kings and crowns regardless, and one brave Brit brandishing a bit of cardboard with a simple message: “Our king is better than yours!”London, UK. Image: Dominic PrestonStill, most of the crowd were on board, with red noses, clown suits, and Pennywise masks dotted throughout, plus costumes ranging from tacos to Roman emperors. “I think tyrants is the better word, and that’s why I dressed up as Caesar, because he was the original,” says Anna, a Long Island native who’s lived in London for three years. “Nobody likes a tyrant. Nobody. And they don’t do well, historically, but they destroy a lot.”For 90 minutes or so the crowd — predominantly American, judging by the accents around me — leaned into the circus theme. Speakers shared the stage with performers, from a comic singalong of anti-Trump protest songs to a protracted pantomime in which a woman in a banana costume exhorted the crowd to pelt a Donald Trump impersonator with fresh peels. London, UK. Image: Dominic PrestonDuring a break in festivities, Alyssa told the crowd, “The most threatening sound to an oligarch is laughter.”— Dominic PrestonProspect Park, Brooklyn, New YorkThe No Kings protest at Brooklyn’s Grand Army Plaza was a calmer affair. Instead of gathering under the picturesque memorial arch, protesters were largely sequestered to a corner right outside Prospect Park, with some streets blocked off by police. The weekly farmers market was in full swing, meaning people cradling bundles of rhubarb were swerving in and out of protest signs that read things like, “Hating Donald Trump is Brat” and “Is it time to get out the pitch forks?” Like during the Hands Off protest in April, New York got rain on Saturday.Prospect Park, Brooklyn. Image: Mia SatoThe area where protesters were gathered made it difficult to count the crowd, but there were hundreds — perhaps a few thousand — people that streamed in and out. At one point, some protesters began marching down the street alongside Prospect Park, while others stayed at Grand Army Plaza to chant, cheer, and hold signs up at oncoming vehicles. With its proximity to the public library, the park, and densely populated neighborhoods, the massive intersection is a high-foot traffic area. Cars blared their horns as they passed, American flags waving in the chilly afternoon breeze.Jane, a Brooklyn resident who stood on the curb opposite the protesters, said she isn’t typically someone who comes out to actions like this: before the No Kings event, she had only ever been to one protest, the Women’s March. (Jane asked that The Verge use her first name only.) Prospect Park, Brooklyn. Image: Mia Sato“I’m deeply concerned about our country,” Jane said, pausing as a long stream of trucks and cars honked continuously in support of the protesters in the background. “I think Trump is behaving as an authoritarian. We’ve seen in Russia, in Hungary, in Hong Kong, that the slide from freedom to not freedom is very fast and very quick if people do not make their voices heard,” Jane said. “I’m concerned that that’s what’s happening in the United States.” Jane also cited cuts to Medicaid and funding for academic research as well as tariffs as being “unacceptable.”Prospect Park, Brooklyn. Image: Mia SatoThe event was peaceful — there were lots of kids present — and people were in good spirits despite the rain. Protest signs ran the gamut from general anti-Trump slogans (“I trust light tampons more than this administration”) to New York City-specific causes like “Andrew Cuomo can’t read” (there is a contenious mayoral election this month). One sign read, “Fix your hearts or die,” an iconic line from the late director, David Lynch’s, Twin Peaks: The Return. And of course, amid nationwide immigration raids that have been escalated by the involvement of the federal government, ICE was top of mind: one sign simply read, “Melt ICE,” and another protester held a large “NO ICE IN NYC” sign. Though it was smaller and more contained than other events, the protest didn’t lack conviction: attendees of all ages stood in the cold rain, chanting and blowing into vuvuzela, banging the lids of pots and pans. At one point a man stood on the median on the street, leading the group in chants of “No justice, no peace.” Cars laid on the horn as they drove by.— Mia SatoAkron, OhioIt’s been raining pretty hard the last few days in Akron, OH, so much that I didn’t think there’d be a large turnout for our chapter of the No Kings protest. But I was emphatically proven wrong as the crowds I saw dwarfed the Tesla Takedown protests last month. Officially, the protest was to take place in front of the John F. Seiberling Federal Building on Main Street in Downtown Akron. But the concentration of people spilled over from that small space down Main Street and up Market Street. All told, though there were no official counts, I estimate somewhere between 500 to 900 people in this blue enclave in Northeast Ohio.The mood was exuberant, buoyed by supporters who honked their horns as they passed. The chorus of horns was nonstop, and when a sanitation truck honked as it went by, cheers got louder. The chants the crowds were singing took on a local flare. Ohio is the home of the Ohio State Buckeyes and anywhere you go, shout “O-H” and you’ll invariably get an “I-O” response. The crowds used that convention to make their own chant, “OH-IO, Donald Trump has got to go.”There was no police presence here and the crowd was very good at policing itself. Ostensibly out of concern for the incidents where people have rammed their cars into protestor crowds, the people here have taken up crossing guard duties, aiding folks who wish to cross Main or Market Streets. Toward the end of my time at the protest, I saw an older gentleman wearing Kent State gear and holding a sign that read, “Remember another time the National Guard was called in?” His sign featured a drawing of the famous photo from the event in which four Kent State students during a protest of the Vietnam War were killed by National Guard troops. I caught up with him to ask him some questions and he told me his name was Chuck Ayers, a professional cartoonist, and was present at the shooting. Akron, OH. Image: Ash Parrish“When I saw the National Guard in front of the federal building in LA,” he told me, “It was just another flashback.”He did not tell me this at the time, but Ayers is a nationally recognized cartoonist, noted for co-creating the comic strip Crankshaft. He’s lived in Ohio his entire life and of course, drew that sign himself. As he was telling me about how seeing news of the National Guard being deployed in LA, I could see him strain to hold back his emotions. He said it still hurts to see this 55 years later, but that he was heartened to see so many people standing here in community and solidarity. He also said that given his pain and trauma he almost didn’t come. When I asked why he showed up when it so obviously causes him pain he said simply, “Because I have to.”— Ash ParrishOneonta, New YorkOn a northward drive to Oneonta — population roughly 15,000, the largest city in New York’s mainly rural Otsego County — one of the most prominent landmarks is a sprawling barn splashed in huge, painted block letters with TRUMP 2024. (The final digits have been faithfully updated every election since 2016.) It’s Trump country, but not uniformly Trumpy country, as evidenced by what I estimated as a hundreds-strong crowd gathered in a field just below Main Street that came together with a friendly county-fair atmosphere. Kids sat on their parents’ shoulders; American flags fluttered next to signs with slogans like SHADE NEVER MADE ANYONE LESS GAY, and attendees grumbled persistently about the event’s feeble sound system, set up on the bed of a pickup truck. It was the kind of conspicuously patriotic, far-from-urban protest that the Trump administration has all but insisted doesn’t exist.Image: Adi RobertsonBeyond a general condemnation of Trump, protest signs repped the same issues being denounced across the country. The wars in Gaza and Ukraine made an appearance, as did Elon Musk and Tesla. A couple of people called out funding cuts for organizations like NPR, one neatly lettered sign reminded us that WEATHER FORECASTING SAVES LIVES, another warned “Keep your nasty little hands off Social Security,” and a lot — unsurprisingly, given the past week’s events — attacked mass deportations and ICE. An attendee who identified himself as Bill, standing behind a placard that blocked most of him from sight, laid out his anger at the administration’s gutting of the Environmental Protection Agency. “I think if it was not for protests, there would be no change,” he told me.The event itself, supported by a coalition including the local chapter of Indivisible, highlighted topics like reproductive justice and LGBTQ rights alongside issues for groups often stereotyped as Republican blocs — there was a speech about Department of Veterans Affairs cuts and a representative from the local Office for the Aging (whose words were mostly lost to the sound system’s whims). Rules for a march around the modest downtown were laid out: no blocking pedestrians or vehicles, and for the sake of families doing weekend shopping, watch the language. “Fuck!” one person yelled indistinctly from the audience. “No, no,” the event’s emcee chided gently. The philosophy, as she put it, was one of persuasion. “We want to build the resistance, not make people angry at us.”Image: Adi RobertsonBut even in a place that will almost certainly never see a National Guard deployment or the ire of a Truth Social post, the Trump administration’s brutal deportation program had just hit close to home. Only hours before the protest commenced, ICE agents were recorded handcuffing a man and removing him in an unmarked black car — detaining what was reportedly a legal resident seeking asylum from Venezuela. The mayor of Oneonta, Mark Drnek, relayed the news to the crowd. “ICE! We see you!” boomed Drnek from the truckbed. “We recognize you for what you are, and we understand, and we reject your vile purpose.”The crowd cheered furiously.

Reading Time: 3 minutes In a recent webinar hosted by MoEngage, QSR marketing experts from Radar and Bottle Rocket came together to unpack the findings of the 2025 State of Cross-Channel Marketing for QSRs report.  With more than 800 total survey responses, including 70 from QSR marketers, this report revealed where quick-service restaurants are focusing their energy, what is holding them back, and the emerging strategies reshaping the guest experience. Here is a recap of the key takeaways, expert insights, and actionable advice shared by our panelists.   Where QSRs Are Focused in 2025: Loyalty, Personalization & Speed The webinar kicked off with a deep dive into shifting priorities. Customer engagement and loyalty emerged as the top focus for QSR marketers in 2025, with 80% of respondents increasing investment in customer experience technology. Mobile-first experiences and real-time personalization are no longer optional; they are essential for effective QSR marketing. Nick Patrick, CEO of Radar, put it simply: “Mobile has become the primary interface between QSRs and their customers. Real-time context is what makes that interface intelligent.” Challenges: Disconnected Data, Tech Silos, and Execution Speed While QSRs have the vision, many struggle with execution.  The report found that 60% of QSR leaders still struggle with personalization, and more than a quarter cited siloed data as a top challenge. The panelists echoed these findings, pointing to fragmented systems and misaligned teams as major hurdles. Brendan shared: “The POS system was designed for speed and accuracy, not personalization. But when you can use even a basic signal, like a loyalty status, to prompt a more human, high-touch experience, it makes a real difference.” Strategies That Work: Start Small, Focus Deep, Earn Trust Panelists emphasized the value of starting small with high-impact initiatives like curbside pickup or loyalty nudges. Cross-functional alignment and choosing scalable tech partners were key themes. “Don’t boil the ocean,” Brendan advised. “Start with one moment in the journey that can be improved and work cross-functionally to get it right.” Earning Location Opt-ins the Right Way Location data is a powerful lever for marketing and operations, but only if opt-ins are earned with care. Nick shared a practical framework: “It comes down to three things: transparency, value, and timing. You can’t just ask up front with no context and expect users to say yes.” He pointed to Outback Steakhouse as a standout example: “They clearly explain the value, guide users through branded screens, and then request OS-level permissions. It’s thoughtful, and it works.” AI in Action: Real Business Impact Artificial intelligence was another hot topic. Brendan shared two areas where AI is delivering real value: smarter cross-sell/upsell and feedback intelligence. “Even simple segmentation by daypart or region can lift basket size. Some tools report a 10% increase just by turning it on,” he said. “It doesn’t need to be complex to be effective.” QSR Webinar Recap: Closing Thoughts Whether optimizing app experiences, trying to unify your tech stack, automating manual processes, or building stronger loyalty loops, the advice was clear: start small, stay focused, and partner with tools and teams that can scale with you.

Bacteria wouldn’t be so bad if we could tell them what to do. “Stop spreading! Stop sticking together! Stop fending off our antibiotics!” A new method is starting to allow scientists to do just that, letting them use light to control certain functions of bacteria. Introduced in a paper published in The European Physical Journal Plus, the preliminary approach could have several potential applications, including a possible avenue for combating antibiotic resistance.The Problem of Antibacterial Resistance Bacteria are behind a variety of diseases, from strep to staph to pneumonia and meningitis, and they attack our bodies in a variety of ways, as well, including through the production of toxins that damage and disrupt our cells. Some of these infections stop on their own, but others are too stubborn, or too serious, to leave untreated. These are the infections that we target with antibiotics — that is, as long as our antibiotics are working.But, because bacteria are constantly changing, they can develop defenses against the antibiotics that we use to stave them off, making these treatments much less effective. That’s the gist of the growing threat posed by antibiotic resistance, which has contributed to millions of deaths since 1990 and is anticipated to contribute to millions more by 2050. Setting out to find a new solution to this growing problem, scientists from the Italian Institute of Technology and the Polytechnic University of Milan embarked on the Engineering of Bacteria to See Light (EOS) project. The project aims to use light to control bacteria, primarily for the fight against antibiotic resistance. And the new method pushes the project closer to achieving that aim. Using light and light-sensitive molecules to adjust the electrical signals that are transmitted across the bacterial membrane, the method impacts the biological activity of bacteria without any alterations to their genetic makeup.“This interplay between light and electrical [signaling] allows us to control key biological processes such as movement, biofilm formation, and antibiotic sensitivity,” said Giuseppe Maria Paternò, a study author and a professor at the Polytechnic University of Milan, according to a press release. “We can influence antibiotic uptake and restore or even enhance the effectiveness of treatments against resistant strains.”Coating Bacteria to Curb Antibiotic ResistanceTo control bacteria, the method takes advantage of a light-sensitive molecule called Ziapin2, which sticks to the bacterial surface. By covering bacteria with this light-sensitive molecule and by subjecting the covered bacteria to light, the scientists were able to modify the electrical signals that were transmitted across their bacterial membranes, transforming the bacteria’s basic functioning. Testing their method on one of the most studied bacterial species, the scientists changed the electrical signaling across the membranes of Bacillus subtilis, a popular model organism that’s often used as a stand-in for Staphylococcus aureus, the bacterium that causes staphylococcus, or staph, infections.When tested, the method modulated the bacteria’s susceptibility to Kanamycin, an intracellular antibiotic that’s frequently used as a treatment for severe bacterial infections after other treatments fail. “Under blue light,” Paternò said in the release, “the effectiveness of Kanamycin was significantly reduced,” indicating that the electrical signaling on the bacterial membrane “plays a crucial role in the drug’s uptake.”Additional research is required to tailor the method to increase the effectiveness of Kanamycin and other antibiotics against bacteria. But for now, it seems that such an outcome could be possible. “This initial assessment […] represents a first step in a completely new field of study,” the scientists state in their paper. “This proof-of-concept study underscores the potential of non-genetic, light-based interventions to modulate bacterial susceptibility in real time. Future work will expand this approach […] ultimately advancing our understanding of bacterial bioelectric regulation and its applications in antimicrobial therapies.”This article is not offering medical advice and should be used for informational purposes only.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.

The drama between US president Donald Trump and his former buddy-in-chief Elon Musk is far from over.As ABC reported today, now that he's been summarily retired from the White House, the billionaire SpaceX boss has been privately venting his frustrations at Trump. One particularly stinging betrayal, per the network's reporting: Trump's sudden withdrawal of Musk's buddy and financial benefactor, Jared Isaacman, from consideration to be the next NASA administrator.As the day progressed, Musk's tension with Trump exploded into public view as history's richest man tweeted or amplified no less than 25 posts blasting Trump's "big, beautiful" tax and spending bill, which takes the form of yet another piece of legislation meant to gut assistance for the poorest Americans while siphoning money to the ultra-wealthy.However, that isn't Musk's issue with the package. Instead, his commentary is centered on the bill's impact on the US national deficit — something he tried and failed to curb in any meaningful way during his time as a pay-to-play government operative.On X-formerly-Twitter, Musk's frenzied posts range from Rand Paul interview clips to hysterical conspiracy peddling. ("America is in the fast lane to debt slavery," he fomented at one point.)"Call your Senator, call your Congressman, bankrupting America is NOT ok!" Musk urged his 220 million followers on X-formerly-Twitter. "KILL the BILL."The tech titan also went out of his way to amplify some low-res footage of Warren Buffett explaining his theoretical plan to reduce the deficit. "Anytime there's a deficit of more than 3 percent of GDP, all sitting members of Congress are ineligible for reelection," the investor suggested, to which Musk replied that "this is the way."Needless to say, a month ago — or even a week — this type of assault on Trump by Musk would have been unthinkable. The bill is also a baffling hill for the tech mogul to die on, especially considering that government spending is what made his tech dynasty possible in the first place. It's more plausible, as Axios notes, that national debt is a smokescreen for other issues nearer to Musk's heart. Most notably, the big beautiful bill is set to cut the electric vehicle tax credits that made Tesla the automotive giant it is today. (Confusingly, as recently as last year, Musk was publicly calling for an end to the tax credit — but that was before his activities in the White House eviscerated Tesla's brand image and sent it deeply into the red.)Of course, that raises another intriguing possibility: that at least some portion of Musk's rage at Trump is essentially kayfabe, with Musk betting that a break from the president could resuscitate at least some enthusiasm for the Tesla brand among the left-leaning customers that he's successfully turned off over the past year.If so, it's not hard to imagine Musk instead accidentally alienating more or less everybody — failing to get the environmental left back on board, but also creating a powerful enemy with Trump, who holds immense power over the government contracts and policy that keep Musk's business empire afloat.More on politics: Elon Musk’s Dad Slams His Son's Whimpering Failure at PoliticsShare This Article

A Deadly Disease Is Eating Away at Caribbean Corals and Wreaking Havoc on Reefs. Could Probiotics Be the Solution? New research suggests the probiotic McH1-7 could help stop the spread of stony coral tissue loss disease among wild corals near Fort Lauderdale, Florida Scientists determined the most effective method of halting the disease was covering a coral colony with a weighted plastic bag, then injecting a seawater solution that contains the probiotic. They left the colony covered for two hours to allow the probiotic bacteria to colonize the coral. Hunter Noren Probiotics can be good for human health. Now, new research suggests they might also help protect coral reefs. A bacterial probiotic helped slow the advance of stony coral tissue loss disease—a fast-spreading and deadly condition—among wild corals in Florida, researchers report today in a new study published in the journal Frontiers in Marine Science. The probiotic may be a good alternative to antibiotics like amoxicillin, which temporarily curb the spread of the disease but must be reapplied frequently. In addition, scientists fear stony coral tissue loss disease may one day become resistant to these antibiotic treatments—just as “superbugs” that infect humans are building resistance to our own drugs. Antibiotics are meant to kill microorganisms, but probiotics are beneficial living microbes. The idea is that a probiotic can be incorporated into corals’ natural microbiomes, ideally offering them longer-lasting protection. First discovered in Florida in 2014, stony coral tissue loss disease attacks the soft tissue of more than 30 different species of coral. Without treatment, the disease eventually kills the corals, and their soft tissue falls off, revealing the white calcium carbonate skeleton below. In just weeks or months, it can devastate a whole colony. Stony coral tissue loss disease can be spread by fish that eat coral, as well as by boaters and divers who do not disinfect their gear. The condition has since expanded its range beyond Florida to reefs throughout the Caribbean. Several years ago, researchers looking at the great star coral (Montastraea cavernosa) discovered a probiotic called Pseudoalteromonas sp. strain McH1-7. Laboratory tests showed McH1-7 stopped or slowed the progression of stony coral tissue loss disease in infected corals. It also helped prevent the disease from spreading to healthy corals. But that was in the lab. Would McH1-7 be similarly effective in the ocean? Researchers were eager to find out, so they set up an experiment on a shallow reef off the coast of Fort Lauderdale. Study co-author Kelly Pitts, a research technician with the Smithsonian Marine Station, applies a paste containing the probiotic directly onto the disease lesion of an infected coral. Hunter Noren Experimenting with wild corals For the study, the scientists focused on 40 great star coral colonies that were showing symptoms of stony coral tissue loss disease. In one experimental condition, the researchers made a paste that contained McH1-7 and applied it directly onto the disease lesions. For comparison, they also applied the same paste, minus the probiotic, to some corals. In another condition, they covered infected coral colonies with weighted plastic bags, then filled the bags with seawater solutions made with and without McH1-7. They left the corals covered for two hours. “This created a little mini-aquarium that kept the probiotics around each coral colony,” says study co-author Valerie Paul, head scientist at the Smithsonian Marine Station at Fort Pierce, Florida, in a statement. The scientists completed all the treatments within the first 4.5 months of the project. Then, they returned periodically to gather tissue and mucus samples from the corals to measure changes to their microbiomes. Over the next 2.5 years, they took photos from a variety of different angles, which they then used to create 3D models that could track the disease’s progression. In the end, the results suggest covering the corals with plastic bags filled with the probiotic seawater solution was the most effective method. More than two years post-treatment, the colonies that received the probiotic bag had lost just 7 percent of their tissue, while colonies in the control bag condition faced 35 percent tissue loss. Scientists applied a probiotic paste directly to disease lesions on some corals. Kelly Pitts The probiotic paste, by contrast, appears to have made the situation worse: The corals that had the probiotic paste applied directly to their lesions lost more tissue than those treated with the control paste, which did not contain McH1-7. “We do not really know what is going on with the probiotic paste treatment,” Paul tells Smithsonian magazine in an email. But she has a few theories. It’s possible the high concentrations of McH1-7 contributed to localized hypoxia, or low-oxygen conditions that further harmed the already stressed corals, she says. Or, the probiotic could have changed the microbiome at the lesion site in some negative way. Another possibility is that McH1-7 produces antibiotics or other substances that were harmful at high concentrations. Amanda Alker, a marine microbiologist at the University of Rhode Island who was not involved with the study, wonders if this finding suggests McH1-7 is beneficial at specific dosages—a question future laboratory research might be able to answer, she tells Smithsonian magazine in an email. She’s also curious to know which specific molecular components of the probiotic are responsible for the increased tissue loss when applied as a paste. More broadly, Alker would like to see additional experiments validating the bag treatment method, but she says this “inventive” technique seems promising. “Their approach is a safer solution than antibiotic treatment methods that have been deployed to combat [stony coral tissue loss disease] in the field so far,” she says. “Further, this is a practical solution that could be implemented widely because it doesn’t require highly specialized equipment and has the ability to be used with any type of microbial solution.” Looking ahead to save reefs Probiotics are likely not a silver bullet for protecting corals. For one, researchers still don’t know exactly what causes stony coral tissue loss disease, which makes it difficult to determine how or why the probiotic works, Paul says. In addition, since the disease has spread to many different parts of the Caribbean, it might be challenging to use the bag treatment technique on all affected colonies. “We would need to develop better methods of deploying the probiotic through time release formulations or other ways to scale up treatments,” Paul says. “Right now, having divers swim around underwater with weighted bags is not a very scalable method.” The researchers have also conducted similar experiments on infected corals located farther south, in the Florida Keys. However, these tests have produced mixed results, probably because of regional differences in stony coral tissue loss disease. This is another hurdle scientists will likely need to overcome if they hope to expand the use of probiotics. “We probably need to develop different probiotics for different coral species and different regions of the Caribbean,” Paul says. Researchers returned to gather samples of tissues and mucus to see how the corals' microbiomes had changed. Hunter Noren Even so, scientists are heartened by the results of the experiments conducted near Fort Lauderdale. With more research, the findings suggest probiotics could be a promising tool for combatting the disease elsewhere. “Coral probiotics is a challenging field, because there are hundreds of different types of bacteria that associate with corals, and there are limitless experiments that need to be performed,” Amy Apprill, a marine chemist at Woods Hole Oceanographic Institution who was not involved with the research, tells Smithsonian magazine in an email. “These researchers made a major advance with their study by demonstrating the utility of whole colony treatment as well as the specific probiotic tested.” Apprill adds that, while antibiotics have been widely used to control stony coral tissue loss disease, scientists haven’t conducted much research to see how these treatments are affecting the plants and creatures that live nearby. “Using a naturally occurring bacterium for disease treatment may result in lessened impacts to other members of the coral reef ecosystem,” she says. Amid rising ocean temperatures, scientists expect to find even more diseased coral colonies in the future. Warmer waters may also allow other pathogens to thrive and proliferate. Against that backdrop, Apprill adds, probiotics and the different methods of applying them will be “major allies” in the fight to save coral reefs. Paul is also optimistic. Through research and field studies, she’s confident researchers will be able to develop interventions that can “help corals better survive changing environments and respond better to diseases and bleaching,” she says.
