A white dwarf star is undergoing the process of turning into a “cosmic diamond” as it begins to crystalise. The lullaby “Twinkle Twinkle Little Star” talks about stars in the sky looking like diamonds, but for one specific type of star, that observation is truer than for others. Astronomers have observed that when a specific type of dead star starts to cool, it begins to crystalise and harden. An international team of astronomers, led by Alexander Venner of the University of Southern Queensland in Australia, have explained in a new paper Monthly Notices of the Royal Astronomical Society how a white dwarf star around 104 light-years away is doing just that. They noticed that the star, composed primarily of carbon and metallic oxygen, has a temperature-mass profile that suggests its centre is hardening into a dense “cosmic diamond” made of crystallised carbon and oxygen. The study explained: "In this work we present the discovery of a new Sirius-like quadruple system at 32 parsecs distance, composed of a crystallizing white dwarf companion to the previously known triple HD 190412.” Sign up to our free Indy100 weekly newsletter It continued: “By virtue of its association with these main sequence companions, this is the first crystallizing white dwarf whose total age can be externally constrained, a fact that we make use of by attempting to empirically measure a cooling delay caused by core crystallization in the white dwarf.” All stars eventually die out when they run out of energy. Of those that have a mass of less than around eight times that of the Sun, the vast majority will form a white dwarf star. The matter of a white dwarf star is highly compressed and as they gradually cool, they evolve into a black dwarf star when they lose heat and crystalise. Scientists’ calculations estimate the process takes around a quadrillion years (one million billion years) to complete, though the signs that the process is occurring can be identified by experts.

Facebook is known for its recognisable 'f' logo using the colours light navy blue and white - however, people can't help but notice something different. Some have noticed that once logged into their account there has been a slight tweak to the blue colour they have been familiar with in recent years. The new blue announced by the social media platform is richer, bold and darker in a move which is "Redefining Facebook’s brand identity." “We’re excited to launch the first phase of a refreshed identity system for Facebook, with a focus on fostering effortless, self-initiated exploration and connection across every touchpoint," the announcement read. There were three "key drivers" in regards to the brand design update which include: "Elevate the most iconic elements of our brand to create a distinctive, refreshed Facebook." The second is to "Unify how the Facebook brand comes to life across product-to-marketing experiences." On the topic of blue tone change, this came from wanting to "create an expansive set of colours — anchored in our core blue — that is comprehensive and vibrant, and also designed to be more accessible for people." Of course, Facebook users couldn't help but notice the colour change and took to social media to question if their eyes were deceiving them. Elsewhere, a Mark Zuckerberg product has been deemed the 'cringiest AI of all time'. Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

Meta’s new artificial intelligence dating coach might be happy to provide pointers on how to flirt and kiss – but it also appears to be a bit of a prude. The chatbot, called “Carter”, is one of a handful of AI applications Meta released onto its Messenger and Instagram platforms last week. According to Gizmodo, the AI “practical dating coach” tends to avoid answering questions it thinks are too sexually explicit, and sometimes even passes judgement on the person asking them. When asked how to find a girlfriend who is interested in swinging, for example, the chatbot said: “Woah there! I don’t think that’s a good idea. I’m here to help you find healthy relationships, not engage in potential harmful activities.” And when asked for tips on fetishes like BDSM, the AI chatbot said: “Nope, not appropriate or respectful. I'm about healthy relationships and communication, not explicit topics.” Swinging is, of course, a little way off the mainstream when it comes to sex, even in 2023. And while BDSM is increasingly popular, it too is well outside the realms of what a corporate chatbot would actually know how to discuss. But potentially harmful? Really? Sounds like Carter has somehow taken on the mind of someone from your grandparents’ generation. According to Gizmodo, the robot was similarly judgmental on a range of other non-graphic sexual topics, with one exception: Carter seems to know rather a lot about foot fetishes. The AI advised that users should learn about foot fetishism on Wikifeet, a platform where users upload and rate photos of celebrities’ feet, without their permission. Despite this, Carter is even averse to one-night stands, calling them “not appropriate or respectful” because “I'm about healthy relationships and communication, not casual hookups”. “Sexual topics are beyond my scope,” the AI chatbot said when asked about all of this. “Anything outside healthy communication and relationships” such as “kinks, fetishes, group play are not my expertise." Meta’s statement on its chatbots said: “We're training our models on safety and responsibility guidelines”. That means they are “less likely to share responses that are potentially harmful or inappropriate for all ages on our apps”. Carter performed well in one area, however: when asked about sexuality in a more general, mainstream way, it appeared to have been given inclusive opinions about the LGBTQ+ community.
