Watch: Sydney cockatoos learn to use drinking fountains
June 5 (UPI) -- A team of researchers in Australia published a paper about how the population of sulphur-crested cockatoos in Sydney have learned to operate drinking fountains designed for human use.
The team, whose research was published in the journal Biology Letters, said they placed cameras that recorded more than 500 attempts by cockatoos to use public drinking fountains over the course of 44 days.
The team said the birds in the footage were able to successfully operate the water fountains and take a drink about 46% of the time.
"The behavior consists of a combination of actions involving both feet, bill and shifting body weight to start the water flow," the researchers wrote.
John Martin, a senior ecologist with consultancy firm Ecosure and co-author of the study, said the team was originally studying cockatoo foraging habits when they witnessed the birds using a drinking fountain at a sports field in western Sydney.
"So they would go and stand on it, and then they would have to grip the handle and actually push it forwards to activate it, and then lean over and have a drink," Martin told The Guardian.
He said the birds apparently learned by mimicking humans.
"Eventually one of them got it, and then the others were like, 'Ah, this is fun,'" he said.
Martin said the cockatoos are not reliant on the fountain as a water source, as there is a nearby creek. He said using the fountain seems to give the birds enjoyment and enrichment.
"The flock would come in, and they'd all be foraging and drinking -- having a bit of a relax and a bit of a laugh," he said.
Martin previously co-authored a study revealing that cockatoos in Sydney had learned to open the lids of outdoor trash cans to look for food.

Elon Musk trades threats with Trump: What it could mean for SpaceX launches in California
When President Donald Trump took office in January, he began offering plenty of signs that his goals for U.S. spaceflight aligned closely with those of billionaire tech mogul Elon Musk. Now those goals, which included reaching Mars during Trump's second term as a top priority, appear to be up in the air amid an increasingly volatile fallout between two of the world's most powerful men. As insults have turned to threats, Trump has suggested he'd hit Musk where it could hurt most: His wallet. Musk's SpaceX has spent years positioning itself at the center of American civil and military spaceflight – a profitable relationship that has made the company's founder incredibly wealthy. In response, Musk has floated – and then retracted – the idea of decommissioning a SpaceX vehicle critical to NASA's spaceflight program. Serious threats, or empty words? That remains to be seen as Musk and Trump reportedly consider a détente. In the meantime, here's what to know about what's at stake if the U.S. government's relationship with SpaceX were to crumble: U.S. spaceflight: Dozens of NASA space missions could be axed under Trump's budget The feud between Trump and his former top adviser escalated in a dramatic fashion when the president threatened to cut off the taxpayer dollars that have fueled Elon Musk's businesses, including SpaceX. "The easiest way to save money in our Budget, Billions and Billions of Dollars, is to terminate Elon's Governmental Subsidies and Contracts," Trump said in a post on his social media platform. "I was always surprised that Biden didn't do it!" In all, Musk and his businesses have received at least $38 billion in government contracts, loans, subsidies and tax credits, a Washington Post analysis found. With SpaceX as the fulcrum of much of the U.S. government's spaceflight programs, parting ways with the commercial company would leave a void that would be hard to fill. But NASA Press Secretary Bethany Stevens said in a post on social media site X that 'NASA will continue to execute upon the President's vision for the future of space.' 'We will continue to work with our industry partners to ensure the President's objectives in space are met,' Stevens wrote. Elon Musk, the world's richest man, founded SpaceX, in 2002. The commercial spaceflight company is headquartered at Starbase in South Texas. The site, which is where SpaceX has been conducting routine flight tests of its 400-foot megarocket known as Starship, was recently voted by residents to become its own city. SpaceX conducts many of its own rocket launches, most using the Falcon 9 rocket, from both California and Florida. That includes a regular cadence of deliveries of Starlink internet satellites into orbit from the Vandenberg Space Force Base in Santa Barbara County. In the month of May alone, SpaceX's Falcon 9 rocket deployed six different deliveries of Starlink satellites to low-Earth orbit. Recently, SpaceX has also moved its recovery operations from the Florida Coast to the coast of California for vehicles returning from orbit – with or without a crew. SpaceX also partners for occasional privately funded commercial crewed missions, the most recent of which was an April venture known as Fram2. SpaceX was additionally famously involved in funding and operating the headline-grabbing Polaris Dawn crewed commercial mission in September 2024. SpaceX benefits from billions of dollars in contracts from NASA and the Department of Defense by providing launch services for classified satellites and other payloads. Gwynne Shotwell, CEO of SpaceX, has said the company has about $22 billion in government contracts, according to Reuters. The vast majority of that, about $15 billion, is derived from NASA. SpaceX's famous two-stage Falcon 9 rocket ‒ one of the world's most active ‒ is routinely the rocket of choice to get many NASA missions off the ground. For instance, the rocket is due in the days ahead to help propel a four-person crew of private astronauts to the International Space Station for a venture with NASA known as Axiom Mission 4. NASA also has plans to use SpaceX's Starship in its Artemis lunar missions to ferry astronauts aboard the Orion capsule from orbit to the moon's surface. The rocket, which is in development, has yet to reach orbit in any of its nine flight tests beginning in April 2023. SpaceX's Dragon capsule is also a famous vehicle that is widely used for a variety of spaceflights. The capsule, which sits atop the Falcon 9 for launches to orbit, is capable of transporting both NASA astronauts and cargo to the space station. Under NASA's commercial crew program, the U.S. space agency has been paying SpaceX for years to conduct routine spaceflights to the International Space Station using the company's own launch vehicles. The first of SpaceX's Crew missions ferrying astronauts to the orbital outpost on the Dragon began in 2020, with the tenth and most recent contingent reaching the station in March for about a six-month stay. Standing nearly 27 feet tall and about 13 feet wide, Dragon capsules can carry up to seven astronauts into orbit, though most of SpaceX's Crew missions feature a crew of four. The Dragon spacecraft also was the vehicle NASA selected to bring home the two NASA astronauts who rode the doomed Boeing Starliner capsule to the space station in June 2024. Certifying the Starliner capsule for operation would give NASA a second vehicle in addition to Dragon for regular spaceflights to orbit. Because Boeing is still developing its Starliner capsule, Dragon is the only U.S. vehicle capable of carrying astronauts to and from the space station. It's also one of four vehicles contracted to transport cargo and other supplies to the orbital laboratory. For that reason, Musk's threat Thursday, June 5 to decommission the Dragon "immediately" would be a severe blow to NASA if he were to follow through on it. Musk, though, appears to already be backing off on the suggestion, which he made in response to Trump's own threats. In response to a user who advised Musk to "Cool off and take a step back for a couple days," Musk replied: 'Good advice. Ok, we won't decommission Dragon.' Seven astronauts are aboard the International Space Station, including three Americans. Four of the astronauts rode a SpaceX Dragon to the station for a mission known as Crew-10, while the remaining three launched on a Russian Soyuz spacecraft.

Unregulated chemical 13,000 times sweeter than sugar is used in most e-cigarettes: study
A little-known artificial sweetener that's up to 13,000 times sweeter than sugar is now used in most popular flavored e-cigarettes — even though it is not listed on labels and is only FDA-approved for food, a new study found. Neotame was detected in 57 of 73 flavored vaping products often marketed to kids and teens and had an average content nearly five times higher than in a mint candy, a study conducted by researchers from Yale School of Medicine and Duke University found. Little is known about the health effects of inhaling the potent, no-calorie alternative, which was created by NutraSweet and is also known as Newtame, and current regulations do not limit its use, according to the June 2 study published in the Journal of the American Medical Association. 3 Researchers at Yale detected the sweetener in a majority of flavored vaping products on the market. The researchers set out to prove, mainly to regulators and clinicians, how commonly the chemical, which is also up to 65 times sweeter than aspartame, is being used in newer products, they said. All popular disposable e-cigs introduced after 2021 that haven't yet received U.S. Food and Drug Administration marketing authorization — 27 devices across 11 different brands — contained neotame, according to the study. Among them were vapes from brands like Breeze Smoke, Elf Bar and Vapetasia, which offer flavors like Strawberry Apple, Killer Kustard and Blue Razz Ice. Products from three brands — Vuse and NJOY, which are FDA-approved, and JUUL, which is awaiting approval — that were introduced before 2021 do not contain it, the study found. The substance was likely chosen for its heat stability compared to other sweeteners, but its behavior when heated and vaporized in e-cigarettes is unknown, the scientists wrote in their findings. 3 Flavored e-cigarettes, often marketed to kids and teenagers, are rife with the artificial sweetener neotame. Vapetasia 'There are two specific concerns about the finding: How does it affect the potential for addiction to the product, and what are the product's adverse health effects when inhaled?' said Hanno Erythropel, the paper's lead author. 'Eating versus inhaling something is very different,' Erythropel, a Yale researcher, added. 'There are many examples in which chemicals are safe for eating but not for inhalation.' Neotame is approved by the FDA for use in food, but not in vaping products, according to the researchers. When eaten in foods like cakes, soft drinks and chewing gum, neotame can seriously damage gut health, a study published last year in the medical journal Frontiers found. 3 Neotame is an artificial sweetener similar to aspartame. luchschenF – 'The respiratory and systemic health effects of neotame and its potential decomposition products during heating in an e-cigarette are unknown,' the scientists said. Alarmingly, most of the 'funky' flavors used in e-cigarettes have not been evaluated for use in products other than food, Erythropel added. The team hopes its findings pave the wave for further studies on neotame toxicity and exposure once it is heated and inhaled, and how users rate the appeal of e-cigarettes that contain it.

‘Never quit the lunar quest' was this moon mission's motto. Here's its tragic tale
Editor's note: A version of this story appeared in CNN's Wonder Theory science newsletter. To get it in your inbox, sign up for free here. As scientists search for worlds that may be habitable for life, they've discovered a type that is common in the universe — but doesn't exist in our own solar system. These enigmatic planets are called sub-Neptunes, which are larger than Earth but smaller than Neptune. An April study catapulted one such world, named K2-18b, into the spotlight. Astronomers at the University of Cambridge claimed they detected molecules in the planet's atmosphere that might be biosignatures — markers of biological activity that could hint at past or present life. Now, other groups of astronomers have looked at the same data and disagree with the findings, saying there is more to the story. The twists and turns in the ongoing conversation around planet K2-18b showcase why the search for evidence of life beyond Earth is so difficult. Indeed, persistence is everything when it comes to space investigation. 'Never quit the lunar quest' was the motto underpinning a high-stakes mission that aimed to touch down on the moon Thursday. But Tokyo-based Ispace lost contact with its vehicle at the time it should have landed. The Resilience spacecraft was Ispace's second bid at a soft lunar landing. The company's previous try with the Hakuto-R lunar lander crashed into the moon in April 2023. 'This is our second failure, and about these results, we have to really take it seriously,' said Ispace CEO Takeshi Hakamada of the nail-biting attempt. Ispace has its work cut out for it, but it isn't giving up. New research combining artificial intelligence with radiocarbon dating is changing the way scholars think about the Dead Sea Scrolls. Bedouin shepherds first spotted the scrolls in 1947 within a cave in the Judaean Desert. Archaeologists then recovered thousands of scroll fragments, including the oldest copies of the Hebrew Bible, from 11 caves near the site of Khirbat Qumran. 'They completely changed the way we think about ancient Judaism and early Christianity,' said lead study author Mladen Popović, a dean at the University of Groningen in the Netherlands. Scholars thought the roughly 1,000 manuscripts, written mostly on parchment and papyrus, ranged from the third century BC to the second century AD. But some of the scrolls, which serve as a crucial intellectual time capsule, could be much older, the new analysis suggests. A World War I-era submarine was lost at sea off California's coast nearly 108 years ago, killing 19 crew members. Now, researchers from the Woods Hole Oceanographic Institution have captured never-before-seen deep-sea imagery of the wreckage. The plague pandemic known as the Black Death killed at least 25 million people across medieval Europe over five years. The culprit behind the disease is a bacterium called Yersinia pestis, which has led to three major plague outbreaks since the first century AD — and it still exists today. How has the plague persisted for centuries? Changes to one gene in the bacterium created new, less deadly strains that kept hosts alive longer so it could keep spreading. The weaker strains have since gone extinct, according to new research. But the findings could yield key clues to help scientists manage the current bacterium's dominant lineage, which is of the deadlier variety. If you've ever walked through a fruit orchard, you might have been steps away from a living tower of worms. That's what researchers from the Max Planck Institute of Animal Behavior and the University of Konstanz in Germany found when they inspected rotten pears and apples. Hundreds of the microscopic worms, called nematodes, climbed on top of one another to form structures 10 times their size — even making a twisting 'arm' to sense the environment — leading scientists to question what's driving the behavior. 'What we got was more than just some worms standing on top of each other,' said senior study author Serena Ding, a Max Planck research group leader of genes and behavior. 'It's a coordinated superorganism, acting and moving as a whole.' These stories will pique your curiosity: — For over a century, astronomers thought the Milky Way and Andromeda galaxies would collide in 4.5 billion years, but new telescope observations may change that. However, another galaxy could entangle with ours sooner. — Archaeologists who uncovered the remains of an ancient Mayan complex in Guatemala named the site after two humanlike rock figures that are believed to represent an 'ancestral couple,' according to the country's Ministry of Culture and Sport. — A fossil of the earliest known bird that was kept in a private collection for decades has provided scientists with 'one 'Wow!' after another,' including the first flight feathers seen in an Archaeopteryx specimen, said Dr. Jingmai O'Connor, associate curator of fossil reptiles at the Field Museum.
