These monsters are (usually) stronger than their non-ex counterparts, and they can come with game-changing abilities that determine how your entire deck plays. In the past, players could create frustratingly fearsome decks consisting of two ex Pokémon supported by trainer and item cards. However, unless you pair together very specific ex Pokémon, you’ll now find yourself losing nearly every game you play. - Timothy Monbleau Read MorePrevious SlideNext SlideList slidesPlease, For The Love Of God, Defeat All Illuminate Stingrays In Helldivers 2Image: Arrowhead Game StudiosYou know what?

show some love for the losers Delightfully irreverent Underdogs isn’t your parents’ nature docuseries Ryan Reynolds narrates NatGeo's new series highlighting nature's much less cool and majestic creatures Jennifer Ouellette – Jun 15, 2025 3:11 pm | 5 The indestructible honey badger is just one of nature's "benchwarmers" featured in Underdogs Credit: National Geographic/Doug Parker The indestructible honey badger is just one of nature's "benchwarmers" featured in Underdogs Credit: National Geographic/Doug Parker Story text Size Small Standard Large Width * Standard Wide Links Standard Orange * Subscribers only   Learn more Narrator Ryan Reynolds celebrates nature's outcasts in the new NatGeo docuseries Underdogs. Most of us have seen a nature documentary or two (or three) at some point in our lives, so it's a familiar format: sweeping majestic footage of impressively regal animals accompanied by reverently high-toned narration (preferably with a tony British accent). Underdogs, a new docuseries from National Geographic, takes a decidedly different and unconventional approach. Narrated by with hilarious irreverence by Ryan Reynolds, the five-part series highlights nature's less cool and majestic creatures: the outcasts and benchwarmers, more noteworthy for their "unconventional hygiene choices" and "unsavory courtship rituals." It's like The Suicide Squad or Thunderbolts*, except these creatures actually exist. Per the official premise, "Underdogs features a range of never-before-filmed scenes, including the first time a film crew has ever entered a special cave in New Zealand—a huge cavern that glows brighter than a bachelor pad under a black light thanks to the glowing butts of millions of mucus-coated grubs. All over the world, overlooked superstars like this are out there 24/7, giving it maximum effort and keeping the natural world in working order for all those showboating polar bears, sharks and gorillas." It's rated PG-13 thanks to the odd bit of scatalogical humor and shots of Nature Sexy Time Each of the five episodes is built around a specific genre. "Superheroes" highlights the surprising superpowers of the honey badger, pistol shrimp, and the invisible glass frog, among others, augmented with comic book graphics; "Sexy Beasts" focuses on bizarre mating habits and follows the format of a romantic advice column; "Terrible Parents" highlights nature's worst practices, following the outline of a parenting guide; "Total Grossout" is exactly what it sounds like; and "The Unusual Suspects" is a heist tale, documenting the supposed efforts of a macaque to put together the ultimate team of masters of deception and disguise (an inside man, a decoy, a fall guy, etc.).  Green Day even wrote and recorded a special theme song for the opening credits. Co-creators Mark Linfield and Vanessa Berlowitz of Wildstar Films are longtime producers of award-winning wildlife films, most notably Frozen Planet, Planet Earth and David Attenborough's Life of Mammals—you know, the kind of prestige nature documentaries that have become a mainstay for National Geographic and the BBC, among others. They're justly proud of that work, but this time around the duo wanted to try something different.

National Geographic A vulture sticks its head inside an elephant carcass to eat. National Geographic A manatee releases flatulence while swimming to lose the buoyancy build up of gas inside its stomach, and descend down the water column. National Geographic/Karl Davies "There is a sense after awhile that you're playing the same animals to the same people, and the shows are starting to look the same and so is your audience," Linfield told Ars. "We thought, okay, how can we do something absolutely the opposite? We've gone through our careers collecting stories of these weird and crazy creatures that don't end up in the script because they're not big or sexy and they live under a rock. But they often have the best life histories and the craziest superpowers." Case in point: the velvet worm featured in the "Superheroes" episode, which creeps up on unsuspecting prey before squirting disgusting slime all over their food. (It's a handy defense mechanism, too, against predators like the wolf spider.) Once Linfield and Berlowitz decided to focus on nature's underdogs and to take a more humorous approach, Ryan Reynolds became their top choice for a narrator—the anti-Richard Attenborough. As luck would have it, the pair shared an agent with the mega-star. So even though they thought there was no way Reynolds would agree to the project, they put together a sizzle reel, complete with a "fake Canadian Ryan Reynolds sound-alike" doing the narration. Reynolds was on set when he received the reel, and loved it so much he recoded his own narration for the footage and sent it back. "From that moment he was in," said Linfield, and Wildstar Films worked closely with Reynolds and his company to develop the final series. "We've never worked that way on a series before, a joint collaboration from day one," Berlowitz admitted. But it worked: the end result strikes the perfect balance between scientific revelation and accurate natural history, and an edgy comic tone. That tone is quintessential Reynolds, and while he did mostly follow the script (which his team helped write), Linfield and Berlowitz admit there was also a fair amount of improvisation—not all of it PG-13.  "What we hadn't appreciated is that he's an incredible improv performer," said Berlowitz. "He can't help himself. He gets into character and starts riffing off [the footage]. There are some takes that we definitely couldn't use, that potentially would fit a slightly more Hulu audience."  Some of the ad-libs made it into the final episodes, however—like Reynolds describing an Aye-Aye as "if fear and panic had a baby and rolled it in dog hair"—even though it meant going back and doing a bit of recutting to get the new lines to fit.

National Geographic Cue the Barry White mood music: Two leopard slugs suspend themselves on a rope of mucus as they entwine their bodies to mate with one another. National Geographic Despite their years of collective experience, Linfield and Berlowitz were initially skeptical when the crew told them about the pearl fish, which hides from predators in a sea cucumber's butt (along with many other species). "It had never been filmed so we said, 'You're going to have to prove it to us,'" said Berlowitz. "They came back with this fantastic, hilarious sequence of a pearl fish reverse parking [in a sea cucumber's anus)." The film crew experienced a few heart-pounding moments, most notably while filming the cliffside nests of barnacle geese for the "Terrible Parents" episode. A melting glacier caused a watery avalanche while the crew was filming the geese, and they had to quickly grab a few shots and run to safety. Less dramatic: cinematographer Tom Beldam had his smartphone stolen by a long-tailed macaque mere minutes after he finished capturing the animal on film. If all goes well and Underdogs finds its target audience, we may even get a follow-up. "We are slightly plowing new territory but the science is as true as it's ever been and the stories are good. That aspect of the natural history is still there," said Linfield. "I think what we really hope for is that people who don't normally watch natural history will watch it. If people have as much fun watching it as we had making it, then the metrics should be good enough for another season." Verdict: Underdogs is positively addictive; I binged all five episodes in a single day. (For his part, Reynolds said in a statement that he was thrilled to "finally watch a project of ours with my children. Technically they saw Deadpool and Wolverine but I don't think they absorbed much while covering their eyes and ears and screaming for two hours.") Underdogs premieres June 15, 2025, at 9 PM/8 PM Central on National Geographic (simulcast on ABC) and will be available for streaming on Disney+ and Hulu the following day.  You should watch it, if only to get that second season.

June 13, 20256 min readAir-Conditioning Can Surprisingly Help the Power Grid during Extreme HeatSwitching on air-conditioning during extreme heat doesn’t have to make us feel guilty—it can actually boost power grid reliability and help bring more renewable energy onlineBy Johanna Mathieu & The Conversation US Imagedepotpro/Getty ImagesThe following essay is reprinted with permission from The Conversation, an online publication covering the latest research.As summer arrives, people are turning on air conditioners in most of the U.S. But if you’re like me, you always feel a little guilty about that. Past generations managed without air conditioning – do I really need it? And how bad is it to use all this electricity for cooling in a warming world?If I leave my air conditioner off, I get too hot. But if everyone turns on their air conditioner at the same time, electricity demand spikes, which can force power grid operators to activate some of the most expensive, and dirtiest, power plants. Sometimes those spikes can ask too much of the grid and lead to brownouts or blackouts.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.Research I recently published with a team of scholars makes me feel a little better, though. We have found that it is possible to coordinate the operation of large numbers of home air-conditioning units, balancing supply and demand on the power grid – and without making people endure high temperatures inside their homes.Studies along these lines, using remote control of air conditioners to support the grid, have for many years explored theoretical possibilities like this. However, few approaches have been demonstrated in practice and never for such a high-value application and at this scale. The system we developed not only demonstrated the ability to balance the grid on timescales of seconds, but also proved it was possible to do so without affecting residents’ comfort.The benefits include increasing the reliability of the power grid, which makes it easier for the grid to accept more renewable energy. Our goal is to turn air conditioners from a challenge for the power grid into an asset, supporting a shift away from fossil fuels toward cleaner energy.Adjustable equipmentMy research focuses on batteries, solar panels and electric equipment – such as electric vehicles, water heaters, air conditioners and heat pumps – that can adjust itself to consume different amounts of energy at different times.Originally, the U.S. electric grid was built to transport electricity from large power plants to customers’ homes and businesses. And originally, power plants were large, centralized operations that burned coal or natural gas, or harvested energy from nuclear reactions. These plants were typically always available and could adjust how much power they generated in response to customer demand, so the grid would be balanced between power coming in from producers and being used by consumers.But the grid has changed. There are more renewable energy sources, from which power isn’t always available – like solar panels at night or wind turbines on calm days. And there are the devices and equipment I study. These newer options, called “distributed energy resources,” generate or store energy near where consumers need it – or adjust how much energy they’re using in real time.One aspect of the grid hasn’t changed, though: There’s not much storage built into the system. So every time you turn on a light, for a moment there’s not enough electricity to supply everything that wants it right then: The grid needs a power producer to generate a little more power. And when you turn off a light, there’s a little too much: A power producer needs to ramp down.The way power plants know what real-time power adjustments are needed is by closely monitoring the grid frequency. The goal is to provide electricity at a constant frequency – 60 hertz – at all times. If more power is needed than is being produced, the frequency drops and a power plant boosts output. If there’s too much power being produced, the frequency rises and a power plant slows production a little. These actions, a process called “frequency regulation,” happen in a matter of seconds to keep the grid balanced.This output flexibility, primarily from power plants, is key to keeping the lights on for everyone.Finding new optionsI’m interested in how distributed energy resources can improve flexibility in the grid. They can release more energy, or consume less, to respond to the changing supply or demand, and help balance the grid, ensuring the frequency remains near 60 hertz.Some people fear that doing so might be invasive, giving someone outside your home the ability to control your battery or air conditioner. Therefore, we wanted to see if we could help balance the grid with frequency regulation using home air-conditioning units rather than power plants – without affecting how residents use their appliances or how comfortable they are in their homes.From 2019 to 2023, my group at the University of Michigan tried this approach, in collaboration with researchers at Pecan Street Inc., Los Alamos National Laboratory and the University of California, Berkeley, with funding from the U.S. Department of Energy Advanced Research Projects Agency-Energy.We recruited 100 homeowners in Austin, Texas, to do a real-world test of our system. All the homes had whole-house forced-air cooling systems, which we connected to custom control boards and sensors the owners allowed us to install in their homes. This equipment let us send instructions to the air-conditioning units based on the frequency of the grid.Before I explain how the system worked, I first need to explain how thermostats work. When people set thermostats, they pick a temperature, and the thermostat switches the air-conditioning compressor on and off to maintain the air temperature within a small range around that set point. If the temperature is set at 68 degrees, the thermostat turns the AC on when the temperature is, say, 70, and turns it off when it’s cooled down to, say, 66.Every few seconds, our system slightly changed the timing of air-conditioning compressor switching for some of the 100 air conditioners, causing the units’ aggregate power consumption to change. In this way, our small group of home air conditioners reacted to grid changes the way a power plant would – using more or less energy to balance the grid and keep the frequency near 60 hertz.Moreover, our system was designed to keep home temperatures within the same small temperature range around the set point.Testing the approachWe ran our system in four tests, each lasting one hour. We found two encouraging results.First, the air conditioners were able to provide frequency regulation at least as accurately as a traditional power plant. Therefore, we showed that air conditioners could play a significant role in increasing grid flexibility. But perhaps more importantly – at least in terms of encouraging people to participate in these types of systems – we found that we were able to do so without affecting people’s comfort in their homes.We found that home temperatures did not deviate more than 1.6 Fahrenheit from their set point. Homeowners were allowed to override the controls if they got uncomfortable, but most didn’t. For most tests, we received zero override requests. In the worst case, we received override requests from two of the 100 homes in our test.In practice, this sort of technology could be added to commercially available internet-connected thermostats. In exchange for credits on their energy bills, users could choose to join a service run by the thermostat company, their utility provider or some other third party.Then people could turn on the air conditioning in the summer heat without that pang of guilt, knowing they were helping to make the grid more reliable and more capable of accommodating renewable energy sources – without sacrificing their own comfort in the process.This article was originally published on The Conversation.
