In 1909, Theodore Roosevelt Embarked on an Ambitious Expedition to East Africa. Here’s Why His Trip Still Matters Today The 26th U.S. president is both lauded as a conservationist and condemned as a big-game hunter. A new book recounts the historic journey on which he helped form a significant collection of animals at the National Museum of Natural History Roosevelt stands between the Sister of Rev. W.F. Bumsted, at that time mother superior of the convent, and the young King Daudi of Uganda, and is surrounded by members of the king's court at St. Mary's Convent, near Kampala, December 22, 1909 Unidentified photographer / Theodore Roosevelt Collection, Houghton Library, Harvard University On a frigid day in March 1909, President Theodore Roosevelt rode slowly through the streets of Washington, D.C., his horse-drawn carriage navigating nearly a foot of snow and slush on the way to the inauguration of his successor, William Howard Taft. The short trip marked Roosevelt’s exit from the White House, but his thoughts were already on the next great journey of his life. Before the month was over, Roosevelt again found himself surrounded by cheering throngs at another historic departure. This time, in New York, Roosevelt was boarding the Hamburg to embark on an adventure that captivated people all over the world: the Smithsonian expedition to British East Africa. Eager to escape the responsibilities of the presidency and give Taft space to govern, Roosevelt longed to get away, enjoy camp life and take to the field with his gun. Roosevelt and his son Kermit would bag elephants, rhinoceroses and lions—but theirs was no simple big-game safari. The 1909-1910 expedition, through parts of what is now Sudan, South Sudan, Uganda and Kenya, included leading scientists. It produced a written and photographic record of an Africa that few in the West had seen, and it diligently described and preserved hundreds of African animals that became a foundational collection for the newly minted National Museum of Natural History. In a new title from Smithsonian Books, Theodore Roosevelt and the Smithsonian Expedition to British East Africa, 1909-1910, readers can experience the expedition in Roosevelt’s own words, written during evenings in his camp tent. The book features 28 excerpts from his chronicle of the trip, African Game Trails: An Account of the African Wanderings of an American Hunter-Naturalist. It’s illustrated with more than 100 fascinating expedition photographs, many taken by Kermit Roosevelt, that capture East Africa’s landscapes, fauna and people. Author Frank H. Goodyear III provides thoughtful historical context and commentary on the expedition’s enduring scientific significance, while exploring how the endeavor reflects the era’s colonial imperialist attitudes toward Africa and its people. “He saw a long tradition of exploration and seeking out new knowledge, and trying to connect worlds together,” Goodyear says. “Of course, exploration is also part of empire building, so that’s a part of the legacy here as well. But I think he very much saw himself as participating in this history of Western exploration.” Accompany Theodore Roosevelt on his Smithsonian safari to East Africa with new context and perspectives. Key takeaways: Theodore Roosevelt's trip to East Africa In 1909, just after his presidency ended, Roosevelt and his son Kermit journeyed to East Africa to collect specimens for the Smithsonian's new National Museum of Natural History. The museum opened to the public in 1910, and the many animal and plant species that Roosevelt and fellow naturalists brought back from the trip helped form a significant collection for the museum of today. It was a crucial time for such a trip. Roosevelt saw how railroads and settlers had forever altered the wild landscape of the American West. In Africa, such change was happening quickly. Roosevelt knew it, as did many others who were scrambling to collect and document African species and ecosystems that were on the brink of radical transformation or extinction. “It’s a real transitional moment in the history of East Africa,” Goodyear says. “Colonization is really beginning to take hold. You have the construction of the Uganda Railroad that literally opens up the territory; you have the beginnings of large-scale ranching and farming; you have colonial settlements being established throughout the land. So it was clear that the impact on indigenous ecosystems was going to be profound.” Roosevelt presents Kermit to King Daudi of Uganda, December 21, 1909 Charles W. Hattersley / Theodore Roosevelt Collection, Houghton Library, Harvard University Roosevelt’s environmental legacy remains complex. He’s been celebrated as a conservationist and criticized for being a big-game hunter, especially by those who had recently witnessed the destruction of the buffalo and the native ecosystems of the American West. “It was controversial in its own day, and it remains controversial. What some perceived as the wanton destruction of wildlife offended many people,” Goodyear says. But Roosevelt was aware of this criticism and determined that this trip would not be an exercise in “game butchery.” “I would a great deal rather have this a scientific trip, which would give it a purpose and character, than simply a prolonged holiday of mine,” he explained in a letter to his friend Henry Cabot Lodge. Roosevelt’s passion for the natural sciences was real and lifelong, notes Darrin Lunde, mammals collections manager at the Smithsonian’s National Museum of Natural History. “Yes, he liked big-game hunting,” Lunde says. “But he was so much more than a hunter. It genuinely was a scientific expedition led by a former president who himself could hold his own as an ornithologist and a mammalogist.” He was an eternal naturalist who collected specimens and started his own museum as a child. “He was one of those guys who liked to get out with his gun, collect things, do taxidermy, describe new species,” Lunde says, noting that Roosevelt originally went to Harvard University to be a naturalist, a part of him that always remained. He kept correspondence with leading naturalists and curators throughout his life. For Roosevelt, this trip “started out as a hunt and very quickly became a museum expedition,” Lunde says. “Because this was a chance to live that boyhood dream of being this great, classical kind of museum naturalist.” Roosevelt on his favorite horse, Tranquillity, in Nairobi, Kenya, July 26, 1909 Paul Thompson / Theodore Roosevelt Collection, Houghton Library, Harvard University Planning the trip in the White House, Roosevelt proposed an intriguing partnership to Secretary of the Smithsonian Charles Doolittle Walcott. If Walcott would provide naturalists who could identify, describe and catalog the species of Africa, and prepare specimens for transport, Roosevelt would donate them as a collection for the new National Museum of Natural History. “Now, it seems to me that this [trip] opens the best chance for the National Museum to get a fine collection not only of the big-game beasts, but of the smaller mammals and birds of Africa; and looking at it dispassionately, it seems to me that the chance ought not to be neglected,” Roosevelt wrote, asking to except only “a very few personal trophies of little scientific value which for some reason I might like to keep.” The deal also had a financial angle. Roosevelt was adamant about paying for his own expenses, but the extensive scientific aspects of the expedition needed funding. Walcott, thrilled at the prospect of securing a landmark collection for the museum and publicizing it by partnering with a former president, was willing to help. The Smithsonian pledged $30,000, all raised by private subscription, avoiding the need to ask Congress for funds, which Roosevelt found ethically and politically distasteful. The museum got more than its money’s worth. Three naturalists—Edgar Mearns, co-founder of the American Ornithologists’ Union and a former military surgeon; Edmund Heller, an expert in large mammals and African game; and J. Alden Loring, a small mammal specialist with experience on Smithsonian scientific expeditions—worked tirelessly collecting mice, bats, birds and shrews, as well as pressing plants and stockpiling interesting insects. Roosevelt’s Life-Histories of African Game Animals chronicled the collection—which includes thousands of mammal, bird and plant specimens. Each one was measured, cataloged and painstakingly preserved for travel. Many were photographed, and expedition members recorded the time and place of collection habitats, the subjects’ behavior in the field, and other details. The effort produced a collection of enduring value. “All of those Roosevelt specimens, for the most part, are still here,” Lunde says. “We have the best collection of East African mammals anywhere, in large part because of the contributions of the Roosevelt expedition.” The collection is irreplaceable, he notes, because it occurred at a time when scientists could get not just the little mammals still collected today, but the elephants, rhinos and other megafauna still prevalent at the time. Even now, Lunde notes, scientists study the collection: “It’s all represented here, and people are coming in all the time and using those specimens, to this day, and publishing on it.” Mammals Exhibits, Natural History Building, Square-Lipped Rhinoceros Group, 1913 Unidentified photographer / Smithsonian Institution Archives Because Roosevelt was one of the world’s most famous people, countless reporters hoped to accompany the expedition and scoop its stories of African adventure. He rejected them all, preferring to control the narrative and tell the story himself—while earning cash to help fund his personal expenses. Scribner’s paid $50,000 for Roosevelt to write 12 articles from the field, set to appear in Scribner’s Monthly, and the publishing house also agreed to print African Game Trails, which would bring the series together in one volume. Kermit, who had trained as the expedition’s primary photographer, and others supplemented this with an incredible array of pictures. These had scientific value; showing African fauna in their native habitats gave a fuller picture of Africa’s ecosystems. They also helped to promote the trip abroad and enhance Roosevelt’s hale and hardy image. “The photography is what first drew me into this project,” says Goodyear, a former curator of photography at the National Portrait Gallery. “They are absolutely extraordinary: extraordinary in the story they tell and extraordinary in their depth. There are more than 1,000 of these photos, and they comprise an incredible record of the people, places and fauna of East Africa.” (Though not part of the expedition, British photographer and filmmaker Cherry Kearton was also in Africa at the time and crossed paths with Roosevelt at several points, shooting footage that would become the 1910 film Roosevelt in Africa.) A herd of elephants in an open forest, 1909 Kermit Roosevelt / Smithsonian Institution Archives Kenyan entomologist Dino Martins has written a valuable afterword to Goodyear’s book. In it, he stresses that, like other African expeditions and collecting trips, Roosevelt’s group depended on support and knowledge from a wide range of individuals and communities, including traders, local leaders, porters and guides who knew how to travel and survive in a challenging landscape. “Though often unacknowledged, that local knowledge and support made it possible for Western explorers to undertake these journeys, for without them their expeditions would certainly have failed,” Martins writes. Despite their importance to the journey, African people are largely absent from Roosevelt’s narrative in African Game Trails. “Outside of himself, Kermit and a few heads of game, nearly all other figures in the book are shadowy, and even Africa itself does not stand out very clearly. The book is avowedly Rooseveltian,” a reviewer from the Philadelphia Inquirer wrote of Roosevelt’s work in 1910. Although the critic dubbed this trait the “greatest charm” of African Game Trails, today, this narrow focus seems like a lost opportunity. “Some of the Kikuyu assistants and guides did become really close to Roosevelt,” Goodyear says. “But you can only kind of tease out the nature of these relationships by a few passing comments.” Tohan with a Marabou stork, 1909 Kermit Roosevelt / Theodore Roosevelt Collection, Houghton Library, Harvard University The expedition has also contributed a lasting scientific legacy in Africa; it was one of the first to extensively collect and document animals and plants beyond the classic big-game species. In 2015, a “Roosevelt Resurvey” expedition included Kenyan scientists and naturalists co-leading fieldwork and research programs that retraced the footsteps of the Roosevelt expedition. It found a rodent species on Mount Kenya that had been described by the Smithsonian naturalists during the original expedition, then “lost” for more than a century afterward. “Two data points on this little rat, over a century apart: a lesson on how much we still need to learn about the world around us,” writes Martins. And while the Roosevelt expedition literally put a site called Rhino Camp on the map by shooting white rhinos there, its work studying the many smaller species and their interactions has since proved very valuable. “They documented the fauna of that region when it was intact, when it still had white rhino roaming around, so we have an accurate picture before it was perturbed in any serious way,” Lunde explains. More than a century later, that landscape has changed dramatically, with rhinos and other animals wiped out and people moved in. But the Uganda Wildlife Authority is working at the Ajai Reserve to restore the ecosystem and its megafauna, including the iconic white rhino. Doing so successfully is a complicated endeavor, but it’s being informed by the time-machine-like snapshot gathered by the early 20th-century expedition. “Without it, efforts to create these parks would just be guesswork,” says Lunde, whose team at the museum is aiding the effort by surveying existing species to contrast with the past. “Now, the Ugandans are actually doing it, and thanks to the Roosevelt-Smithsonian expedition they are able to refer to a record of what these habitats were like in their natural state.” From left to right: Theodore Roosevelt, R.J.

Contributor: 'Save the whales' worked for decades, but now gray whales are starving

The once-booming population that passed California twice a year has cratered because of retreating sea ice. A new kind of intervention is needed.

Recently, while sailing with friends on San Francisco Bay, I enjoyed the sight of harbor porpoises, cormorants, pelicans, seals and sea lions — and then the spouting plume and glistening back of a gray whale that gave me pause. Too many have been seen inside the bay recently.California’s gray whales have been considered an environmental success story since the passage of the 1972 Marine Mammal Protection Act and 1986’s global ban on commercial whaling. They’re also a major tourist attraction during their annual 12,000-mile round-trip migration between the Arctic and their breeding lagoons in Baja California. In late winter and early spring — when they head back north and are closest to the shoreline, with the moms protecting the calves — they can be viewed not only from whale-watching boats but also from promontories along the California coast including Point Loma in San Diego, Point Lobos in Monterey and Bodega Head and Shelter Cove in Northern California.In 1972, there were some 10,000 gray whales in the population on the eastern side of the Pacific. Generations of whaling all but eliminated the western population — leaving only about 150 alive today off of East Asia and Russia. Over the four decades following passage of the Marine Mammal Protection Act, the eastern whale numbers grew steadily to 27,000 by 2016, a hopeful story of protection leading to restoration. Then, unexpectedly over the last nine years, the eastern gray whale population has crashed, plummeting by more than half to 12,950, according to a recent report by the National Oceanic and Atmospheric Administration, the lowest numbers since the 1970s.Today’s changing ocean and Arctic ice conditions linked to fossil-fuel-fired climate change are putting this species again at risk of extinction.While there has been some historical variation in their population, gray whales — magnificent animals that can grow up to 50 feet long and weigh as much as 80,000 pounds — are now regularly starving to death as their main food sources disappear. This includes tiny shrimp-like amphipods in the whales’ summer feeding grounds in the Arctic. It’s there that the baleen filter feeders spend the summer gorging on tiny crustaceans from the muddy bottom of the Bering, Chuckchi and Beaufort seas, creating shallow pits or potholes in the process. But, with retreating sea ice, there is less under-ice algae to feed the amphipods that in turn feed the whales. Malnourished and starving whales are also producing fewer offspring.As a result of more whales washing up dead, NOAA declared an “unusual mortality event” in California in 2019. Between 2019 and 2025, at least 1,235 gray whales were stranded dead along the West Coast. That’s eight times greater than any previous 10-year average.While there seemed to be some recovery in 2024, 2025 brought back the high casualty rates. The hungry whales now come into crowded estuaries like San Francisco Bay to feed, making them vulnerable to ship traffic. Nine in the bay were killed by ship strikes last year while another 12 appear to have died of starvation.Michael Stocker, executive director of the acoustics group Ocean Conservation Research, has been leading whale-viewing trips to the gray whales’ breeding ground at San Ignacio Lagoon in Baja California since 2006. “When we started going, there would be 400 adult whales in the lagoon, including 100 moms and their babies,” he told me. “This year we saw about 100 adult whales, only five of which were in momma-baby pairs.” Where once the predators would not have dared to hunt, he said that more recently, “orcas came into the lagoon and ate a couple of the babies because there were not enough adult whales to fend them off.”Southern California’s Gray Whale Census & Behavior Project reported record-low calf counts last year.The loss of Arctic sea ice and refusal of the world’s nations recently gathered at the COP30 Climate Summit in Brazil to meet previous commitments to reduce greenhouse gas emissions suggest that the prospects for gray whales and other wildlife in our warming seas, including key food species for humans such as salmon, cod and herring, look grim.California shut down the nation’s last whaling station in 1971. And yet now whales that were once hunted for their oil are falling victim to the effects of the petroleum or “rock oil” that replaced their melted blubber as a source of light and lubrication. That’s because the burning of oil, coal and gas are now overheating our blue planet. While humans have gone from hunting to admiring whales as sentient beings in recent decades, our own intelligence comes into question when we fail to meet commitments to a clean carbon-free energy future. That could be the gray whales’ last best hope, if there is any.David Helvarg is the executive director of Blue Frontier, an ocean policy group, and co-host of “Rising Tide: The Ocean Podcast.” He is the author of the forthcoming “Forest of the Sea: The Remarkable Life and Imperiled Future of Kelp.”

Pills that communicate from the stomach could improve medication adherence

MIT engineers designed capsules with biodegradable radio frequency antennas that can reveal when the pill has been swallowed.

In an advance that could help ensure people are taking their medication on schedule, MIT engineers have designed a pill that can report when it has been swallowed.The new reporting system, which can be incorporated into existing pill capsules, contains a biodegradable radio frequency antenna. After it sends out the signal that the pill has been consumed, most components break down in the stomach while a tiny RF chip passes out of the body through the digestive tract.This type of system could be useful for monitoring transplant patients who need to take immunosuppressive drugs, or people with infections such as HIV or TB, who need treatment for an extended period of time, the researchers say.“The goal is to make sure that this helps people receive the therapy they need to help maximize their health,” says Giovanni Traverso, an associate professor of mechanical engineering at MIT, a gastroenterologist at Brigham and Women’s Hospital, and an associate member of the Broad Institute of MIT and Harvard.Traverso is the senior author of the new study, which appears today in Nature Communications. Mehmet Girayhan Say, an MIT research scientist, and Sean You, a former MIT postdoc, are the lead authors of the paper.A pill that communicatesPatients’ failure to take their medicine as prescribed is a major challenge that contributes to hundreds of thousands of preventable deaths and billions of dollars in health care costs annually.To make it easier for people to take their medication, Traverso’s lab has worked on delivery capsules that can remain in the digestive tract for days or weeks, releasing doses at predetermined times. However, this approach may not be compatible with all drugs.“We’ve developed systems that can stay in the body for a long time, and we know that those systems can improve adherence, but we also recognize that for certain medications, we can’t change the pill,” Traverso says. “The question becomes: What else can we do to help the person and help their health care providers ensure that they’re receiving the medication?”In their new study, the researchers focused on a strategy that would allow doctors to more closely monitor whether patients are taking their medication. Using radio frequency — a type of signal that can be easily detected from outside the body and is safe for humans — they designed a capsule that can communicate after the patient has swallowed it.There have been previous efforts to develop RF-based signaling devices for medication capsules, but those were all made from components that don’t break down easily in the body and would need to travel through the digestive system.To minimize the potential risk of any blockage of the GI tract, the MIT team decided to create an RF-based system that would be bioresorbable, meaning that it can be broken down and absorbed by the body. The antenna that sends out the RF signal is made from zinc, and it is embedded into a cellulose particle.“We chose these materials recognizing their very favorable safety profiles and also environmental compatibility,” Traverso says.The zinc-cellulose antenna is rolled up and placed inside a capsule along with the drug to be delivered. The outer layer of the capsule is made from gelatin coated with a layer of cellulose and either molybdenum or tungsten, which blocks any RF signal from being emitted.Once the capsule is swallowed, the coating breaks down, releasing the drug along with the RF antenna. The antenna can then pick up an RF signal sent from an external receiver and, working with a small RF chip, sends back a signal to confirm that the capsule was swallowed. This communication happens within 10 minutes of the pill being swallowed.The RF chip, which is about 400 by 400 micrometers, is an off-the-shelf chip that is not biodegradable and would need to be excreted through the digestive tract. All of the other components would break down in the stomach within a week.“The components are designed to break down over days using materials with well-established safety profiles, such as zinc and cellulose, which are already widely used in medicine,” Say says. “Our goal is to avoid long-term accumulation while enabling reliable confirmation that a pill was taken, and longer-term safety will continue to be evaluated as the technology moves toward clinical use.”Promoting adherenceTests in an animal model showed that the RF signal was successfully transmitted from inside the stomach and could be read by an external receiver at a distance up to 2 feet away. If developed for use in humans, the researchers envision designing a wearable device that could receive the signal and then transmit it to the patient’s health care team.The researchers now plan to do further preclinical studies and hope to soon test the system in humans. One patient population that could benefit greatly from this type of monitoring is people who have recently had organ transplants and need to take immunosuppressant drugs to make sure their body doesn’t reject the new organ.“We want to prioritize medications that, when non-adherence is present, could have a really detrimental effect for the individual,” Traverso says.Other populations that could benefit include people who have recently had a stent inserted and need to take medication to help prevent blockage of the stent, people with chronic infectious diseases such as tuberculosis, and people with neuropsychiatric disorders whose conditions may impair their ability to take their medication.The research was funded by Novo Nordisk, MIT’s Department of Mechanical Engineering, the Division of Gastroenterology at Brigham and Women’s Hospital, and the U.S. Advanced Research Projects Agency for Health (ARPA-H), which notes that the views and conclusions contained in this article are those of the authors and should not be interpreted as representing the official policies, either expressed or implied, of the United States Government.

A young female manatee washed up alone on a beach in Tortuguero National Park early on January 5, sparking a coordinated effort by local authorities to save the animal. The calf, identified as a Caribbean manatee, appeared separated from its mother, with no immediate signs of her in the area. Park rangers received the first alert around 8 a.m. from visitors who spotted the stranded calf. Staff from the National System of Conservation Areas (SINAC) quickly arrived on site. They secured the animal to prevent further harm and began searching nearby waters and canals for the mother. Despite hours of monitoring, officials found no evidence of her presence. “The calf showed no visible injuries but needed prompt attention due to its age and vulnerability,” said a SINAC official involved in the operation. Without a parent nearby, the young manatee faced risks from dehydration and predators in the open beach environment. As the day progressed, the Ministry of Environment and Energy (MINAE) joined the response. They decided to relocate the calf for specialized care. In a first for such rescues in the region, teams arranged an aerial transport to move the animal safely to a rehabilitation facility. This step aimed to give the manatee the best chance at survival while experts assess its health. Once at the center, the calf received immediate feeding and medical checks. During one session, it dozed off mid-meal, a sign that it felt secure in the hands of caretakers. Biologists now monitor the animal closely, hoping to release it back into the wild if conditions allow. Manatees, known locally as manatíes, inhabit the coastal waters and rivers of Costa Rica’s Caribbean side. They often face threats from boat strikes, habitat loss, and pollution. Tortuguero, with its network of canals and protected areas, serves as a key habitat for the species. Recent laws have strengthened protections, naming the manatee a national marine symbol to raise awareness. This incident highlights the ongoing challenges for wildlife in the area. Local communities and tourists play a key role in reporting sightings, which can lead to timely interventions. Authorities encourage anyone spotting distressed animals to contact SINAC without delay. The rescue team expressed gratitude to those who reported the stranding. Their quick action likely saved the calf’s life. As investigations continue, officials will determine if environmental factors contributed to the separation. For now, the young manatee rests under professional care, a small win for conservation efforts in Limón.

New Records Reveal the Mess RFK Jr. Left When He Dumped a Dead Bear in Central Park

Robert F. Kennedy Jr. says he left a bear cub's corpse in Central Park in 2014 to "be fun." Records newly obtained by WIRED show what he left New York civil servants to clean up.

This story contains graphic imagery.On August 4, 2024, when now-US health secretary Robert F. Kennedy Jr. was still a presidential candidate, he posted a video on X in which he admitted to dumping a dead bear cub near an old bicycle in Central Park 10 years prior, in a mystifying attempt to make the young bear’s premature death look like a cyclist’s hit and run.WIRED's Guide to How the Universe WorksYour weekly roundup of the best stories on health care, the climate crisis, new scientific discoveries, and more. At the time, Kennedy said he was trying to get ahead of a story The New Yorker was about to publish that mentioned the incident. But in coming clean, Kennedy solved a decade-old New York City mystery: How and why had a young black bear—a wild animal native to the state, but not to modern-era Manhattan—been found dead under a bush near West 69th Street in Central Park?WIRED has obtained documents that shed new light on the incident from the New York City Department of Parks and Recreation via a public records request. The documents—which include previously unseen photos of the bear cub—resurface questions about the bizarre choices Kennedy says he made, which left city employees dealing with the aftermath and lamenting the cub’s short life and grim fate.A representative for Kennedy did not respond for comment. The New York Police Department (NYPD) and the Parks Department referred WIRED to the New York Department of Environmental Conservation (NYDEC). NYDEC spokesperson Jeff Wernick tells WIRED that its investigation into the death of the bear cub was closed in late 2014 “due to a lack of sufficient evidence” to determine if state law was violated. They added that New York’s environmental conservation law forbids “illegal possession of a bear without a tag or permit and illegal disposal of a bear,” and that “the statute of limitations for these offenses is one year.”The first of a number of emails between local officials coordinating the handling of the baby bear’s remains was sent at 10:16 a.m. on October 6, 2014. Bonnie McGuire, then-deputy director at Urban Park Rangers (UPR), told two colleagues that UPR sergeant Eric Handy had recently called her about a “dead black bear” found in Central Park.“NYPD told him they will treat it like a crime scene so he can’t get too close,” McGuire wrote. “I’ve asked him to take pictures and send them over and to keep us posted.”“Poor little guy!” McGuire wrote in a separate email later that morning.According to emails obtained by WIRED, Handy updated several colleagues throughout the day, noting that the NYDEC had arrived on scene, and that the agency was planning to coordinate with the NYPD to transfer the body to the Bronx Zoo, where it would be inspected by the NYPD’s animal cruelty unit and the ASPCA. (This didn’t end up happening, as the NYDEC took the bear to a state lab near Albany.)Imagery of the bear has been public before—local news footage from October 2014 appears to show it from a distance. However, the documents WIRED obtained show previously unpublished images that investigators took of the bear on the scene, which Handy sent as attachments in emails to McGuire. The bear is seen laying on its side in an unnatural position. Its head protrudes from under a bush and rests next to a small patch of grass. Bits of flesh are visible through the bear’s black fur, which was covered in a few brown leaves.Courtesy of NYC Parks

U.S. Military Ends Practice of Shooting Live Animals to Train Medics to Treat Battlefield Wounds

The 2026 National Defense Authorization Act bans the use of live animals in live fire training exercises and prohibits "painful" research on domestic cats and dogs

U.S. Military Ends Practice of Shooting Live Animals to Train Medics to Treat Battlefield Wounds The 2026 National Defense Authorization Act bans the use of live animals in live fire training exercises and prohibits “painful” research on domestic cats and dogs Sarah Kuta - Daily Correspondent January 5, 2026 12:00 p.m. The U.S. military will no longer shoot live goats and pigs to help combat medics learn to treat battlefield injuries. Pexels The United States military is no longer shooting live animals as part of its trauma training exercises for combat medics. The 2026 National Defense Authorization Act, which was enacted on December 18, bans the use of live animals—including dogs, cats, nonhuman primates and marine mammals—in any live fire trauma training conducted by the Department of Defense. It directs military leaders to instead use advanced simulators, mannequins, cadavers or actors. According to the Associated Press’ Ben Finley, the bill ends the military’s practice of shooting live goats and pigs to help combat medics learn to treat battlefield injuries. However, the military is allowed to continue other practices involving animals, including stabbing, burning and testing weapons on them. In those scenarios, the animals are supposed to be anesthetized, per the AP. “With today’s advanced simulation technology, we can prepare our medics for the battlefield while reducing harm to animals,” says Florida Representative Vern Buchanan, who advocated for the change, in a statement shared with the AP. He described the military’s practices as “outdated and inhumane” and called the move a “major step forward in reducing unnecessary suffering.” Quick fact: What is the National Defense Authorization Act? The National Defense Authorization Act, or NDAA, is a law passed each year that authorizes the Department of Defense’s appropriated funds, greenlights the Department of Energy’s nuclear weapons programs and sets defense policies and restrictions, among other activities, for the upcoming fiscal year. Organizations have opposed the military’s use of live animals in trauma training, too, including the Physicians Committee for Responsible Medicine and the People for the Ethical Treatment of Animals. PETA, a nonprofit animal advocacy group, described the legislation as a “major victory for animals” that will “save countless animals from heinous cruelty” in a statement. The legislation also prohibits “painful research” on domestic cats and dogs, though exceptions can be made under certain circumstances, such as interests of national security. “Painful” research includes any training, experiments or tests that fall into specific pain categories outlined by the U.S. Department of Agriculture. For example, military cats and dogs can no longer be exposed to extreme environmental conditions or noxious stimuli they cannot escape, nor can they be forced to exercise to the point of distress or exhaustion. The bill comes amid a broader push to end the use of live animals in federal tests, studies and training, reports Linda F. Hersey for Stars and Stripes. After temporarily suspending live tissue training with animals in 2017, the U.S. Coast Guard made the ban permanent in 2018. In 2024, U.S. lawmakers directed the Department of Veterans Affairs to end its experiments on cats, dogs and primates. And in May 2025, the U.S. Navy announced it would no longer conduct research testing on cats and dogs. As the Washington Post’s Ernesto Londoño reported in 2013, the U.S. military has used animals for medical training since at least the Vietnam War. However, the practice largely went unnoticed until 1983, when the U.S. Army planned to anesthetize dogs, hang them from nylon mesh slings and shoot them at an indoor firing range in Maryland. When activists and lawmakers learned of the proposal, they decried the practice and convinced then-Defense Secretary Caspar Weinberger to ban the shooting of dogs. However, in 1984, the AP reported the U.S. military would continue shooting live goats and pigs for wound treatment training, with a military medical study group arguing “there is no substitute for the live animals as a study object for hands-on training.” In the modern era, it’s not clear how often and to what extent the military uses animals, per the AP. And despite the Department of Defense’s past efforts to minimize the use of animals for trauma training, a 2022 report from the Government Accountability Office, the watchdog agency charged with providing fact-based, nonpartisan information to Congress, determined that the agency was “unable to fully demonstrate the extent to which it has made progress.” The Defense Health Agency, the U.S. government entity responsible for the military’s medical training, says in a statement shared with the AP that it “remains committed to replacement of animal models without compromising the quality of medical training,” including the use of “realistic training scenarios to ensure medical providers are well-prepared to care for the combat-wounded.” Animal activists say technology has come a long way in recent decades so, beyond the animal welfare concerns, the military simply no longer needs to use live animals for training. Instead, military medics can simulate treating battlefield injuries using “cut suits,” or realistic suits with skin, blood and organs that are worn by a live person to mimic traumatic injuries. However, not everyone agrees. Michael Bailey, an Army combat medic who served two tours in Iraq, told the Washington Post in 2013 that his training with a sedated goat was invaluable. “You don’t get that [sense of urgency] from a mannequin,” he told the publication. “You don’t get that feeling of this mannequin is going to die. When you’re talking about keeping someone alive when physics and the enemy have done their best to do the opposite, it’s the kind of training that you want to have in your back pocket.” Get the latest stories in your inbox every weekday.
