Elon Musk has stopped X, formerly Twitter, from showing information about links posted to the site. Until the last day, when someone posted a link on X, it showed as an image and the article’s headline, allowing people to see what they would be reading when they clicked. Now, however, that description has been removed. Instead, the article shows up as a normal picture, with the name of the website showing up small in the corner to show that it is a link. The update prompted confusion from many readers, who said that it was unclear whether a post included a link and what that might be a link to. Many news organisations publicly complained that it had forced them to change their strategy for posting on the site, given they could previously depend on Twitter to show the headline of posts. Many tweets that had included links and were posted before the change instantly became incomprehensible, since they had been written to respond to the headline that had pulled through from the article. Mr Musk has said that he ordered the change to improve the site. When the update was first rumoured, in a Forbes report in August, he responded by saying that it was “coming from me directly” and that it will “greatly improve the esthetics”. But it may also be an attempt to encourage users to stay on the site for longer, rather than clicking away to links. Since Mr Musk took over Twitter around a year ago, he has often focused on increasing the amount of time that users spend in its feed. “Our algorithm tries to optimize time spent on X, so links don’t get as much attention, because there is less time spent if people click away,” Mr Musk wrote in a recent tweet. “Best thing is to post content in long form on this platform.” It is also one of a range of recent decisions that looks to put Mr Musk in conflict with news sites. Earlier this year, for instance, X appeared to have added a delay when users clicked on some news sites and other rivals such as Instagram and Blue Sky. Users found that pages would not load for five seconds.

For centuries we’ve been told that the Moon is made of cheese but now, it turns out, the Earth is more like butter. Or, at least, its inner core is. A new study led by experts at the University of Texas (UT) and collaborators in China found that iron atoms at the very centre of our world move around much more than previously thought, and the implications could be huge. Scientists have long sought to dissect the insides of our planet but it isn’t easy, given that we have no way of directly exploring its core. The deepest hole humans have ever dug – branded the "entrance to hell" – extended an impressive 12,263m (40,230ft) down, but even that doesn’t come close to breaking through the crust to the layers beneath. Still, thanks to techniques like seismic tomography – which analyses how waves of energy travel through different materials during earthquakes – we’ve been able to map out the world’s interior. Now, researchers have used lab experiments and AI algorithms to shed a striking new light on the heart of the planet. "Seismologists have found that the centre of the Earth, called the inner core, is surprisingly soft, kind of like how butter is soft in your kitchen," Youjun Zhang, a Sichuan University professor who co-led the investigation, said in a statement shared with Phys.org. "The big discovery that we've found is that solid iron becomes surprisingly soft deep inside the Earth because its atoms can move much more than we ever imagined. This increased movement makes the inner core less rigid, weaker against shear forces." The findings are significant because they could help explain the role that the inner core plays in generating the world’s magnetic field. They could also help us understand a number of the inner core’s key properties, which have long flummoxed experts. "Now, we know about the fundamental mechanism that will help us with understanding the dynamic processes and evolution of the Earth's inner core," Jung-Fu Lin, one of the study's lead authors, explained. Given that it is impossible for scientists to directly extract specimens from the inner core, Lin and his colleagues recreated it in miniature. They took a small iron plate, shot it with a fast-moving projectile, and collected the resulting temperature, pressure and velocity data, which they then fed into an AI computer model. Using this machine learning system, they were able to scale up the sample iron atoms configuration to mimic the atomic environment within the inner core. At this beefed-up scale, the researchers observed groups of atoms moving about while still maintaining their overall structure. Inner Core iron atom motion model University of Texas This movement could explain why seismic measurements of the inner core reveal an environment that's softer and more malleable than would be expected at such pressures, Prof Zhang explained. Around half of the energy that goes into generating the Earth's magnetic field can be attributed to the inner core, with the rest coming from the outer core, according to the UT team. Thanks to Zhang, Lin and their colleagues, we now have a clearer understanding of the inner core’s machinations at an atomic level, which could help inform how energy and heat are generated at the heart of the planet. This could also shed light on how the inner and outer core work together to generate the Earth’s magnetic field – a key ingredient in making a planet habitable.

Facebook users have shared images of cartoon characters wielding weapons, naked celebrities, and child soldiers – all created using the app’s new AI-generated sticker feature. Parent company Meta unveiled the new feature last week, allowing Facebook, Instagram, Messenger and Instagram users to generate stickers with artificial intelligence by writing prompts. “I don’t think anyone involved has thought anything through,” 3D artist and illustrator Pier-Olivier Desbiens wrote on X, formerly known as Twitter, who used the tool to create stickers with the prompts ‘Waluigi rifle’, ‘child soldier’, ‘Karl Marx large breasts’ and ‘Trudeau buttocks’. “We really do live in the stupidest future imaginable,” he wrote. Another user shared an AI-generated sticker of conspiracy theorist Alex Jones kissing a dog. “It’s completely unhinged,” they wrote. The Independent has reached out to Meta for comment. The new AI stickers are currently only available to a limited number of English-language users, with Meta yet to confirm whether a wider roll out is planned. “Using technology from Llama 2 and our foundational model for image generation called Emu, our AI tool turns your text prompts into multiple unique, high-quality stickers in seconds,” Meta announced in a blog post last week. “This new feature... provides infinitely more options to convey how you’re feeling at any moment.” Meta claims that billions of stickers are sent by Facebook, Instagram, Messenger and WhatsApp users each month, having first introduced the feature in 2013. Other AI-generated image tools, such as OpenAI’s DALL-E 3, have limits in place to prevent misuse. Users are unable to generate images featuring violent content or real people, though other generative AI platforms exist that do not place limitations on the ways content can be generated. In its blog post announcing the new feature, Meta noted that there was a chance that AI tools could be misused, which is why their introduction is being done on a “step by step” basis. “In keeping with our commitment to responsible AI, we also stress test our products to improve safety performance and regularly collaborate with policymakers, experts in academia and civil society, and others in our industry to advance the responsible use of this technology,” the post stated. “We’ll continue to iterate on and improve these features as the technologies evolve and we see how people use them in their daily lives.” Read More Pixel 8: Google unveils ‘AI-centred’ iPhone rival Facebook and Instagram users face monthly fee for ad-free version Zuckerberg says Metaverse can bring back the dead – virtually Meta just took a step towards its dream of the metaverse

Vegetarianism may be written in your DNA, a study has found. According to new research which analysed 5000 vegetarians and 300,000 meat eaters, there are genes associated with how well someone is able to adhere to a vegetarian lifestyle. Researchers identified three genes that are strongly identified and another 31 that are potentially identified with vegetarianism. In a genetic analysis, the researchers saw that vegetarians are more likely than non-vegetarians to have different variations of these genes. This might be because of how different people process lipids, or fats. Several of the genes that the study found to be associated with vegetarianism had to do with metabolising lipids and given plants and meat differ in the complexity of their lipids, it may be that some people genetically need some lipids offered by meat. “At this time we can say is that genetics plays a significant role in vegetarianism and that some people may be genetically better suited for a vegetarian diet than others,” said lead study author Dr. Nabeel Yaseen, professor emeritus of pathology at Northwestern University’s Feinberg School of Medicine. “A large proportion of self-described vegetarians actually report consuming meat products when responding to detailed questionnaires,” he said. “This suggests that many people who would like to be vegetarian are not able to do so, and our data suggest that genetics is at least part of the reason.” Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.
