Cockatoos know how to pick the right tools for the job

Cockatoos know how to pick the right tools for the job

The New York Times reports: Cockatoos contain contradictions. “They behave like gremlins,” said Antonio Osuna-Mascaró, a biologist at the University of Veterinary Medicine Vienna. His colleague Alice Auersperg agreed. “Imagine a toddler with pliers in their head,” she said, that is also able to fly. But just like toddlers, cockatoos can be sweet and curious, always exploring the world around them. Dr. Auersperg and other researchers showed the innateness of this curiosity in 2021, when they reported that wild Goffin’s…

More incursions or more detections? Mystery surrounds airborne objects shot down over U.S. and Canada

More incursions or more detections? Mystery surrounds airborne objects shot down over U.S. and Canada

The Guardian reports: Questions remain after the US government shot down two high-altitude objects, one near Deadhorse, Alaska along the north-eastern Alaskan coast and a second near Yukon, Canada, that have yet to be identified. Canadian prime minister Justin Trudeau tweeted on Saturday afternoon that he had ordered the takedown of an unidentified object in Canadian airspace. Though efforts by the navy, coast guard and FBI are under way to recover the object shot down near Alaska, officials had yet…

Hominids used stone tool kits to butcher animals earlier than once thought

Hominids used stone tool kits to butcher animals earlier than once thought

Science News reports: Nearly 3 million years ago, hominids employed stone tool kits to butcher hippos and pound plants along what’s now the shores of Kenya’s Lake Victoria, researchers say. Evidence of those food preparation activities pushes back hominids’ use of these tool kits, known as Oldowan implements, by roughly 300,000 years, say paleoanthropologist Thomas Plummer of Queen’s College, City University of New York and colleagues. That makes these finds possibly the oldest known stone tools. Several dating techniques place…

Chinese balloon part of vast aerial surveillance program, U.S. says

Chinese balloon part of vast aerial surveillance program, U.S. says

The Washington Post reports: The U.S. intelligence community has linked the Chinese spy balloon shot down on Saturday to a vast surveillance program run by the People’s Liberation Army, and U.S. officials have begun to brief allies and partners who have been similarly targeted. The surveillance balloon effort, which has operated for several years partly out of Hainan province off China’s south coast, has collected information on military assets in countries and areas of emerging strategic interest to China including…

What ChatGPT and generative AI mean for science

What ChatGPT and generative AI mean for science

Nature reports: In December, computational biologists Casey Greene and Milton Pividori embarked on an unusual experiment: they asked an assistant who was not a scientist to help them improve three of their research papers. Their assiduous aide suggested revisions to sections of documents in seconds; each manuscript took about five minutes to review. In one biology manuscript, their helper even spotted a mistake in a reference to an equation. The trial didn’t always run smoothly, but the final manuscripts were…

Microplastics are filling the skies. Will they affect the climate?

Microplastics are filling the skies. Will they affect the climate?

Nicola Jones writes: Plastic has become an obvious pollutant over recent decades, choking turtles and seabirds, clogging up our landfills and waterways. But in just the past few years, a less-obvious problem has emerged. Researchers are starting to get concerned about how tiny bits of plastic in the air, lofted into the skies from seafoam bubbles or spinning tires on the highway, might potentially change our future climate. “Here’s something that people just didn’t think about — another aspect of…

The difference between speaking and thinking

The difference between speaking and thinking

Matteo Wong writes: Language is commonly understood to be the “stuff” of thought. People “talk it out” and “speak their mind,” follow “trains of thought” or “streams of consciousness.” Some of the pinnacles of human creation—music, geometry, computer programming—are framed as metaphorical languages. The underlying assumption is that the brain processes the world and our experience of it through a progression of words. And this supposed link between language and thinking is a large part of what makes ChatGPT and similar…

The DOJ’s antitrust case against Google is ambitious but risky

The DOJ’s antitrust case against Google is ambitious but risky

CNBC reports: The Department of Justice’s latest challenge to Google’s tech empire is an ambitious swing at the company with the potential to rearrange the digital advertising market. But alongside the possibility of great reward comes significant risk in seeking to push the boundaries of antitrust law. “DOJ is going big or going home here,” said Daniel Francis, who teaches antitrust at NYU School of Law and previously worked as deputy director of the Federal Trade Commission’s Bureau of Competition,…

How wind, sun and water can power the world

How wind, sun and water can power the world

The Guardian reports: “Combustion is the problem – when you’re continuing to burn something, that’s not solving the problem,” says Prof Mark Jacobson. The Stanford University academic has a compelling pitch: the world can rapidly get 100% of its energy from renewable sources with, as the title of his new book says, “no miracles needed”. Wind, water and solar can provide plentiful and cheap power, he argues, ending the carbon emissions driving the climate crisis, slashing deadly air pollution and…

New data show that light pollution is rapidly obscuring the night sky

New data show that light pollution is rapidly obscuring the night sky

Science News reports: The night sky has been brightening faster than researchers realized, thanks to the use of artificial lights at night. A study of more than 50,000 observations of stars by citizen scientists reveals that the night sky grew about 10 percent brighter, on average, every year from 2011 to 2022. In other words, a baby born in a region where roughly 250 stars were visible every night would see only 100 stars on their 18th birthday, researchers report…

Human noise drowns out communication between dolphins

Human noise drowns out communication between dolphins

The New York Times reports: Mammals in the ocean swim through a world of sound. But in recent decades, humans have been cranking up the volume, blasting waters with noise from shipping, oil and gas exploration and military operations. New research suggests that such anthropogenic noise may make it harder for dolphins to communicate and work together. When dolphins cooperated on a task in a noisy environment, the animals were not so different from city dwellers on land trying to…

Iran says face recognition will identify women breaking hijab laws

Iran says face recognition will identify women breaking hijab laws

Wired reports: Last month, a young woman went to work at Sarzamineh Shadi, or Land of Happiness, an indoor amusement park east of Iran’s capital, Tehran. After a photo of her without a hijab circulated on social media, the amusement park was closed, according to multiple accounts in Iranian media. Prosecutors in Tehran have reportedly opened an investigation. Shuttering a business to force compliance with Iran’s strict laws for women’s dress is a familiar tactic to Shaparak Shajarizadeh. She stopped…

Complex supply chains may have appeared more than 3,000 years ago

Complex supply chains may have appeared more than 3,000 years ago

Science News reports: Long-distance supply chains, vulnerable to disruptions from wars and disease outbreaks, may have formed millennia before anyone today gasped at gas prices or gawked at empty store shelves. Roughly 3,650 to 3,200 years ago, herders and villagers who mined tin ore fueled long-distance supply chains that transported the metal from Central Asia and southern Turkey to merchant ships serving societies clustered around the Mediterranean, a new study finds. Remote communities located near rare tin deposits tapped into…

A single Iranian attack drone found to contain parts from more than a dozen U.S. companies

CNN reports: Parts made by more than a dozen US and Western companies were found inside a single Iranian drone downed in Ukraine last fall, according to a Ukrainian intelligence assessment obtained exclusively by CNN. The assessment, which was shared with US government officials late last year, illustrates the extent of the problem facing the Biden administration, which has vowed to shut down Iran’s production of drones that Russia is launching by the hundreds into Ukraine. CNN reported last month…

80% of new cars sold in Norway are now electric vehicles

80% of new cars sold in Norway are now electric vehicles

CBS News reports: Electric vehicles accounted for almost four out of every five new car registrations in Norway last year, setting a new record, according to figures released Monday. Led by U.S. carmaker Tesla, which topped the list with a 12.2% market share, 138,265 new electric cars were sold in the Scandinavian country last year, representing 79.3% of total passenger car sales, the Norwegian Road Federation (OFV) said in a statement. In doing so, Norway, which is both a major…

Capitalism excels at innovation but is failing at maintenance

Capitalism excels at innovation but is failing at maintenance

Andrew Russell and Lee Vinsel write: Innovation is a dominant ideology of our era, embraced in America by Silicon Valley, Wall Street, and the Washington DC political elite. As the pursuit of innovation has inspired technologists and capitalists, it has also provoked critics who suspect that the peddlers of innovation radically overvalue innovation. What happens after innovation, they argue, is more important. Maintenance and repair, the building of infrastructures, the mundane labour that goes into sustaining functioning and efficient infrastructures,…
