Rescued giant moths emerge from cocoons in Mexico's sprawling capital
'When I get here and find this, I jump with delight,' said María Eugenia Díaz Batres, who has been caring for insects at the Museum of Natural History and Environmental Culture in Mexico City for nearly six decades.
The mating pair of 'four mirrors' moths as they're popularly known in Mexico, or scientifically as Rothschildia orizaba, are evidence that the museum's efforts to save some 2,600 cocoons rescued from an empty lot were worth the trouble.
The moths, whose numbers have fallen in Mexico City due to urbanization, have cultural relevance in Mexico.
'The Aztecs called them the 'butterfly of obsidian knives,' Itzpapalotl,' Díaz Batres said. 'And in northern Mexico they'd fill many of these cocoons with little stones and put them on their ankles for dances.'
These cocoons arrived at the museum in late December.
'They gave them to us in a bag and in a box, all squeezed together with branches and leaves, so my first mission was to take them out, clean them,' Díaz Batres said.
Mercedes Jiménez, director of the museum in the capital's Chapultepec park, said that's when the real adventure began since they had never received anything like this before.
Díaz Batres had the cocoons hung in any place she thought they might do well, including her office where they hang from lines crisscrossing above her table. It has allowed her to watch each stage of their development closely.
The moths only survive for a week or two as adults, but they give Díaz Batres tremendous satisfaction, especially when she arrives at her office and new moths 'are at the door, on the computer.'
So she tries to help them 'complete their mission' and little by little their species recovers.

Scientists get a rare peek inside of an exploding star
NEW YORK (AP) — Scientists for the first time have spotted the insides of a dying star as it exploded, offering a rare peek into stellar evolution. Stars can live for millions to trillions of years until they run out of fuel. The most massive ones go out with a bang in an explosion called a supernova. Using telescopes that peer deep into space, researchers have observed many such explosions. The cosmic outbursts tend to jumble up a dying star's layers, making it hard for scientists to observe the inner structure. But that wasn't the case for the new discovery, a supernova called 2021yfj located in our Milky Way galaxy. The collapsing star's outermost layers of hydrogen and helium had peeled away long ago, which wasn't surprising. But the star's dense, innermost layers of silicon and sulfur had also shed during the explosion. 'We have never observed a star that was stripped to this amount,' said Northwestern University's Steve Schulze, who was part of the discovery team that published the research Wednesday in the journal Nature. The finding lends evidence to ideas scientists have about how large stars look near the end of their lives, organized into layers with lighter elements on the outside and heavier ones close to the core. 'Because so many of the layers had been stripped off this star, this basically confirmed what those layers were,' said Anya Nugent, who studies supernovas at the Harvard-Smithsonian Center for Astrophysics. She was not involved with the new research. It's not yet clear how this star got so whittled down — whether its layers were flung off violently in the final stages of its life or yanked away by a twin star. Future research may yield clues, though scientists acknowledged such an event may be tough to capture again. ___ The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute's Department of Science Education and the Robert Wood Johnson Foundation.

Manhattan-sized interstellar object appears to emit its own light: Harvard scientist
Interstellar object 3I/ATLAS — which is zooming through our inner solar system — appears to be emitting its own light, according to Harvard astrophysicist Avi Loeb. The observation by Loeb, if verified, would contradict NASA's classification of the Manhattan-sized object as a comet, the scientist argues in a new blog post. 4 An image of 3I/ATLAS taken by the Hubble Telescope on July 21, according to NASA. AP Advertisement Loeb and a colleague analyzed photos released by NASA of the object in determining that the source of its glow is likely not from the sun. The astrophysicist wrote the 'brightness profile around 3I/ATLAS implies that the nucleus dominates the observed light.' 'The simplest interpretation is that the nucleus of 3I/ATLAS produces most of the light,' he wrote in the paper published Sunday. Advertisement The level of light observed on 3I/ATLAS could be achieved 'from a source diameter smaller than 100 meters,' according to Loeb. This shift in understanding the light source would also mean that 3I/ATLAS is quite smaller than initially thought, and more comparable in size to the two other known interstellar objects, Oumuamua and Borisov. 4 Images taken by the Hubble Telescope show the object glowing at its front end and not having any comet tail. Jewitt et al. 2025 If 3I/ATLAS were reflecting light, it would mean the object was 12 miles long, which is improbable, according to the astrophysicist. Advertisement Loeb speculated that the nucleus of the object could in fact be nuclear — and possibly an engine crafted by an alien people. 'A natural nuclear source could be a rare fragment from the core of a nearby supernova that is rich in radioactive material. This possibility is highly unlikely, given the scarce reservoir of radioactive elements in interstellar space,' Loeb wrote. 4 The trajectory of the object brings it through our inner Solar System in perfect position to possibly observe Earth. NASA/JPL-Caltech 'Alternatively, 3I/ATLAS could be a spacecraft powered by nuclear energy, and the dust emitted from its frontal surface might be from dirt that accumulated on its surface during its interstellar travel,' Loeb conjectured, adding, 'This cannot be ruled out, but requires better evidence to be viable.' Advertisement Loeb argued this conclusion is bolstered by 3I/Atlas' 'fine-tuned trajectory.' That suspicious trajectory will see the object blocked from Earth's view by the sun just as it will get its closest to our pale blue dot. It will also make passes of Mars and Jupiter, adding to Loeb's suspicions that this could be a reconnaissance mission conducted by an inquisitive and interstellar intelligence. 4 The object was first discovered by the NASA-funded ATLAS survey telescope in Chile on July1, according to NASA. ATLAS/University of Hawaii/NASA Loeb is now calling for the Mars Reconnaissance Orbiter to use its HiRISE camera to make observations of 3I/ATLAS when it passes by 17 million miles away in the first week of October. He has also called for NASA to direct its Juno craft, currently orbiting Jupiter, to make what observations it can when 3I/ATLAS passes nearby next spring. NASA has maintained that 3I/ATLAS is merely a comet. Loeb pointed out to The Post that earlier this year NASA claimed to discover a new asteroid which turned out to merely be the Tesla Roadster that Elon Musk launched into space.

'Silicon Valley' star Kumail Nanjiani says Elon Musk hated HBO satire
Elon Musk hated HBO's 'Silicon Valley' so much that he reportedly felt compelled to gripe about its satirical portrayal of lame 'tech bro' parties — and brag to the show's star about the superior shindigs he has attended himself. Kumail Nanjiani said that the world's richest mogul complained to him that the tech gatherings depicted on the HBO comedy were nothing like his exclusive billionaire bashes. 'He was like, all the parties I go to are much cooler than these parties,' Nanjiani, 47, told comedian Mike Birbiglia on his podcast last week about meeting Musk. 5 Kumail Nanjiani, star of the hit HBO satire 'Silicon Valley,' said that Elon Musk panned the show. YouTube / Mike Birbiglia 5 Musk supposedly told Nanjiani, that 'all the parties I go to are much cooler than these parties.' AP The 'Silicon Valley' star had the perfect comeback: 'I was like, yeah man, you're one of the richest people in the world. We're, like, losers on the show. Of course your parties are better than my parties.' Nanjiani's revelation offers a rare glimpse into Musk's thinking on how Hollywood portrays the tech elite — even in a show that never actually featured him as a character. The Tesla CEO's reaction sparked renewed interest in the real Silicon Valley party scene, which in years past has gained notoriety for pushing boundaries far beyond what HBO ever showed. 'Silicon Valley,' which was created by Mike Judge of 'Beavis and Butt-Head' fame, ran for 53 episodes across six seasons from 2014 to 2019. The series followed Richard Hendricks, an awkward programmer building a startup called Pied Piper with his misfit friends. The show earned five consecutive Emmy nominations for Outstanding Comedy Series by savagely mocking 'brogrammer culture' and the eccentricities of tech billionaires. While Musk never appeared as a character, the series featured various fictional moguls like Gavin Belson of 'Hooli' who parodied traits associated with real tech titans. Nanjiani revealed he'd met several Silicon Valley heavyweights during the show's run, including Meta CEO Mark Zuckerberg. But Musk stood out for his particularly negative reaction, according to the actor. The HBO show particularly irritated Musk with its opening scene featuring Kid Rock performing at a sparsely attended tech party, according to Nanjiani. 'The first scene of the show is — it's such a funny opening — it's Kid Rock playing on stage,' Nanjiani explained, 'and then it cuts to the audience and it's at, clearly, some tech party. There's seven nerdy dudes standing there, (and) nobody's paying attention.' 'Elon was upset. He was like, 'Well, the parties I go to are much cooler than these parties,'' the 'Big Sick' star recalled. 5 Nanjiani is seen alongside co-stars Martin Starr (left) and Thomas Middleditch (right) in a scene from 'Silicon Valley.' AP 'It was like, 'Yeah man, you're one of the richest people in the world. We're like losers on the show. Of course your parties are better than my parties. What are you talking about?'' Back in 2014, Musk showed up at a special screening of 'Silicon Valley' and made it clear he wasn't impressed, according to Vox. Speaking to reporters afterward, Musk complained that Judge had missed the essence of the tech world's party scene. 'I really feel like Mike Judge has never been to Burning Man, which is Silicon Valley,' Musk said at the afterparty. 5 While Musk never appeared as a character, the series featured various fictional moguls like Gavin Belson of 'Hooli' who parodied traits associated with real tech titans. 'If you haven't been, you just don't get it. You could take the craziest LA party and multiply it by a thousand, and it doesn't even get fucking close to what's in Silicon Valley. The show didn't have any of that.' Musk contrasted Silicon Valley's social culture with Hollywood's, adding: 'The parties in Silicon Valley are amazing because people don't care about how they're perceived socially, which I don't think Mike got. Hollywood is a place where people always care about what the public will think of them, and it's f–king sad, and the show felt more like that.' 'I've lived in Hollywood 12 years, and I've never been to a f–king good party,' Musk said. He even went so far as to suggest he'd personally take Judge to Burning Man—though it's unknown if the offer was ever taken up. The billionaire's complaint about party accuracy becomes more intriguing considering what really goes down at elite tech gatherings. Emily Chang's explosive 2018 book 'Brotopia' exposed secretive Silicon Valley parties featuring drug use and open sexual behavior among venture capitalists and founders. 5 Back in 2014, Musk showed up at a special screening of 'Silicon Valley' and made it clear he wasn't impressed. AP These events allegedly involved MDMA and 'cuddle puddles' encouraging intimacy, with women reporting feeling pressured to participate. Chang claimed Musk attended at least one such gathering in 2017 at investor Steve Jurvetson's house — though Musk vigorously disputed her characterization. The SpaceX founder insisted he thought it was a costume party and saw nothing inappropriate before leaving early. 'Nerds on a couch are not a 'cuddle puddle,'' Musk told Wired in 2018. 'I was hounded all night by DFJ-funded entrepreneurs, so went to sleep around 1am. Nothing remotely worth writing about happened.' His reference to Draper Fisher Jurvetson-funded entrepreneurs suggests even Musk's 'cooler' parties involve relentless networking and startup pitches. DFJ is a prominent Silicon Valley venture capital firm that funds technology startups. The Post has sought comment from Nanjiani and Musk.
