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 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.

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

See the First Photos and Videos of the Rare Subalpine Woolly Rat, a Massive but Elusive Rodent in New Guinea’s Mountains Working with local Indigenous people, biologist František Vejmělka spent six months surveying the creatures that live on Mount Wilhelm in Papua New Guinea Trail cameras recorded nocturnal subalpine woolly rats roaming around in search of plants to eat. Czech Academy of Sciences The subalpine woolly rat lives high in the mountains of New Guinea, where it spends its nights searching for plants to eat and its days hiding in underground burrows or tree canopies. This furry rodent is massive, measuring more than 2.5 feet from nose to tail and tipping the scales at more than four pounds. But despite its large size, the subalpine woolly rat (Mallomys istapantap) is incredibly elusive. First described in 1989, the species was only known to scientists because of a few museum specimens, and it had never been photographed in the wild—until now. František Vejmělka, a biologist at the Czech Academy of Sciences and the University of South Bohemia, spent six months exploring the highlands of Papua New Guinea. With help from local Indigenous people, he surveyed and genetically identified 61 species of rodents and marsupials found on Mount Wilhelm, a 14,793-foot peak and the country’s highest mountain. But perhaps his most significant work centered around the subalpine woolly rat. Vejmělka captured the first photos and videos of the mysterious creature in the wild. He also caught a few individuals, which allowed him to take the first biometric measurements of males and gather data about the rats’ behavior, diet and parasites. He shared his findings in a paper published April 18 in the journal Mammalia. By capturing several subalpine woolly rats, František Vejmělka was able to take the first biometric measurements of males of the species. Czech Academy of Sciences “It’s astonishing that such a large and striking animal has remained so poorly studied. How much more is there to discover about the biodiversity of tropical mountains?” Vejmělka says in a statement shared last week. The subalpine woolly rat is the biggest rodent in Australia and Oceania, and it’s one of the largest in the world. It’s a “striking and formidable creature,” with three-inch-long paws, sharp teeth and dense, shaggy fur covering most of its body, according to the statement. But these rodents are only active at night, and they live between 10,500 and 12,140 feet above sea level. Their rugged, remote habitats, coupled with their nocturnal habits, have made them difficult for researchers to study. Subalpine Woolly Rat Filmed For The First Time Watch on Vejmělka was up for the challenge. He wanted to know more about this mysterious species, as well as the mammalian diversity of New Guinea more broadly. For help, he turned to several tribes living on Mount Wilhelm. Their support and collaboration were crucial to the project, he says. The rats spend their days hiding in underground burrows or tree canopies, but they come out at night to search for food. Czech Academy of Sciences “If it weren’t for the Indigenous hunters who accompanied me in the mountains and helped me locate the animals, I would never have been able to collect this data,” he says in the statement. From trail camera footage and biometric observations, Vejmělka was able to glean several new insights into the lives of these mysterious creatures. He learned they primarily eat ferns and other plant material, for example, and that both males and females have a reddish brown color on their chests, reports IFLScience’s Eleanor Higgs. The species’ large size is likely due to “insular gigantism,” a biological phenomenon in which animals on islands evolve to become larger than those on the mainland, Vejmělka tells Live Science’s Jess Thomson in an email. Scientists think the rodents’ predecessors first arrived on New Guinea roughly five million years ago. Without much competition to worry about, they’ve been able to adapt to the rainforest landscape and thrive. “Their ancestors arrived from Asia to the island completely absent of any other terrestrial placental mammals (only marsupials and monotremes),” Vejmělka adds to Live Science.

A Succinea snail that has been infected by a zombifying parasiteshutterstock/JoostP Rise of the Zombie Bugs Mindy Weisberger (Johns Hopkins University Press) A snail, eyestalks pulsing with coloured stripes, leaves the safety of the shade and oozes its way onto an exposed leaf, where it catches the beady eye of a bird. The larger animal mistakes those eyestalks for delicious caterpillars and pounces; in the process, it accidentally gobbles up the parasitic worms infesting the Succinea putris snail. This poor mollusc is far from alone: worms, wasps and other creatures that manipulate their hosts’ behaviour are common in the…
