May 18, 2025Accidental Alchemy, Flamingo Food Tornado, and Kosmos-482 LandsKosmos-482 crash-lands, physicists turn lead to gold and animals show some clever behaviors. Anaissa Ruiz Tejada/Scientific AmericanSUBSCRIBE TO Science QuicklyHappy Monday, listeners! For Scientific American’s Science Quickly, this is Allison Parshall filling in for Rachel Feltman. Let’s kick off the week with a quick roundup of some of the latest science news.First, an update on that doomed Soviet-era spacecraft Rachel mentioned last week. After spending more than half a century orbiting Earth, the Kosmos-482 probe made a crash landing on May 10. According to a post on the app Telegram from Russian space agency Roscosmos, the spacecraft crashed into the Indian Ocean somewhere west of Jakarta, the capital of Indonesia. Space.com reports that other space agencies have estimated different landing spots for the probe, from locations on land in South Asia to stretches of the eastern Pacific. We may never know exactly where Kosmos-482 finally came to rest. In any case, we haven’t heard any reports of falling space junk causing harm to humans, so it seems likely the object crashed somewhere out of the way.Now for some accidental alchemy. Despite the wishes of medieval scholars, there’s no way to turn lead into gold, right? Wrong. Physicists at the Large Hadron Collider apparently did just that—very briefly, but still. The scientists published a description of this magical-sounding transformation earlier this month in the journal Physical Review C.

Instead of smashing head-on, the nuclei usually pass very close to one another. In these near-misses, the powerful electric field from one nucleus can shake up the other. If the field is strong enough, it can knock out three protons from an incoming lead nucleus. Since gold has three fewer protons than lead, this transforms the lead into gold.The researchers estimate that 89,000 gold nuclei are produced per second during these experiments. That means that between 2015 and 2018—the accelerator’s second run, which is when the scientists collected this data—the collider produced 29 trillionths of a gram of gold. Unfortunately for any prospectors at CERN, those atoms tend to get obliterated in about a microsecond. Nature reports that another CERN accelerator also observed this alchemical reaction during a 2002 to 2004 run. But because that experiment used less energy, less gold was produced.In public health news, Centers for Disease Control and Prevention data released last Wednesday indicates a massive drop in overdose deaths between 2023 and 2024. In the 45 years that the CDC has collected equivalent data, the biggest one-year dip seen previously was 4 percent in 2018, according to the Associated Press. Deaths dropped from about 110,000 in 2023 to roughly 80,000 in 2024, which represents a nearly 27 percent decrease. The AP reports that experts mentioned several possible factors behind the drop, including the increased availability of naloxone for treating overdoses.It’s important to note that, while this is promising news, we still have a long way to go. Overdose deaths are still higher than they were before the COVID pandemic, and overdose remains the leading cause of death for people in the U.S. between ages 18 and 44. If you don’t already carry naloxone with you in case you encounter someone experiencing an overdose, consider looking into what resources your state and county offer for training and distribution.

You’re probably picturing the birds standing calmly in crystal clear water. But according to a study published last Monday in the journal Proceedings of the National Academy of Sciences, they’re surprisingly busy just beneath the surface.Similar to the way spiders use webs to trap prey, the study authors say, flamingos create little water tornados to coax food straight into their mouths.First, the birds use their feet to churn sediment up. Then they jerk their heads up, turning those small whorls of sediment into vortexes. Meanwhile, the animals chatter their beaks to create even more water movement, pulling the swirling sediment into their mouths. From there, the flamingos can filter out tiny prey such as brine shrimp—but it seems like this filter feeding is a lot less passive than it looks.In other animal news, it turns out that chimps use leaves for everything from first aid to bathroom hygiene. In a study published Tuesday in Frontiers in Ecology and Evolution, researchers describe their observations of two different communities of chimpanzees in Uganda. The researchers identified numerous instances of “self-care” using leaves, from dabbing wounds to packing them with chewed-up plant matter. The chimps sometimes offered this care to others, too. That’s similar to behavior other researchers reported last year in orangutans over in Indonesia. Orangutans have also been seen applying juice made from saliva and the leaves of a plant with anti-inflammatory properties all over their bodies, which scientists suspect they might be doing to relieve joint and muscle pain.Plants seem to be part of a larger wellness routine for chimps, too: the scientists also saw them using leaves to clean themselves up after pooping or having sex. The researchers even described one instance of what they called “prosocial postcoital penis wiping,” which means one chimp leant another a hand with intimate personal hygiene.While these aren’t the first documented cases of first aid in nonhuman animals—or even in chimps, who have been seen putting smashed insects in their wounds, possibly for medicinal purposes—scientists are excited to see evidence that medicinal plant use might be more widespread than expected among our close relatives. That could suggest that wound care goes way, way back in our evolutionary history.That’s all for this week’s news roundup.

Feeding Flamingos Create Underwater Tornado-Like Vortices to Capture Their Prey, Study Finds Rather than passively filter-feeding, the birds use their heads, beaks and feet to generate motion in the water that funnels invertebrates into their mouths A new study reveals how Chilean flamingos are so adept at finding food. Victor Ortega Jiménez / UC Berkeley Flamingos have a natural ability to filter out food, like shrimp and worms, from the surrounding water, even in the most food-poor environments. Now, a new study published Monday in Proceedings of the National Academy of Sciences reveals how the birds use the power of physics to nab their elusive prey. Victor Ortega Jiménez, an integrative biologist at the University of California, Berkeley, and lead author of the study, first became interested in flamingos’ eating behavior after a visit to Zoo Atlanta in 2019. The pink birds stomped their feet and submerged their beaks, but from the surface, he saw only ripples. The researcher wanted to know what was happening underwater. “We don’t know anything about what is happening inside,” he says in a statement. “That was my question.” Flamingo model tornado vortex Watch on So, Ortega Jiménez and his team took a closer look with the help of three Chilean flamingos at the Nashville Zoo. They trained the animals to feed from a water-filled tray over several weeks and used high-speed cameras and lasers to monitor the process. Then, the researchers created 3D printed models of the birds’ heads, feet and bills to more closely study how they make the water and particles move. The final step of the work involved attaching a real flamingo beak to a machine that snaps it open and shut, with a small pump to simulate the bird’s tongue. The researchers found that the flamingos use the motion of water to their advantage, combining techniques to funnel water—and the invertebrates within it—to their mouths. They’ll stomp their feet in dance-like motions to bring food up to the surface. Then, they’ll quickly bob their heads up and down to create tornado-like underwater vortices that help catch their prey more efficiently. The birds also snap or “chatter” their beaks and move their tongues in and out—and that chattering allows flamingos to capture seven times more brine shrimp. “We are challenging the idea that flamingos are just passive filter feeders,” says Ortega Jiménez to Rachel Nuwer at the New York Times. “Just as spiders produce webs, flamingos produce vortices.” Tornado flamingo chattering Watch on The team calculated just how quickly the flamingos chattered their beaks and bobbed their heads. To create a tornado-like vortex, a bird would retract its head in a short burst of speed at nearly 16 inches per second. The chattering motion involved the lower beak snapping about 12 times per second. The study is “an outstanding demonstration of how biological form and motion can control the surrounding fluid to serve a functional role,” adds Sunghwan Jung, a biophysicist at Cornell University who was not involved in the study, to the New York Times. Flamingo brine filtering foot Watch on Flamingos’ feeding prowess can even benefit other birds: A 2018 study found that Wilson’s phalaropes can double their food intake by following behind a stomping flamingo. Next, Ortega Jiménez wants to study what goes on inside flamingos’ beaks during feeding, in hopes that it can inspire new technologies that harness the strength of vortices to capture toxic algae or microplastics from water. “These behaviors that look kind of silly are generating these really useful water flows,” Elizabeth Brainerd, a functional morphologist at Brown University who was not involved with the study, told Elizabeth Pennisi at Science when the work was presented at a conference in 2023. “That’s unexpected … and quite elegant.” Get the latest stories in your inbox every weekday.
