Scientists have found that one of the key pillars of theory around how life works – that it depends on carbon – may not be the case on other planets. Here on Earth, life depends on organic compounds which are composed of carbon, and often involve other elements such as sulphur, oxygen, hydrogen, nitrogen and phosphorus. With organic compounds, life is partly sustained by chemical interactions called autocatalysis, which are self-sustaining. That means they produce molecules which then enable the reaction to happen again, and do not need any outside influence to keep going on. In the new study, scientists looked for autocatalysis in non-organic compounds. The theory is that if autocatalysis helps drive a process called abiogenesis – the origin process for life – then this origin process could also come from non-organic matter. Betül Kaçar, an astrobiologist, bacteriologist and evolutionary biologist at the University of Wisconsin-Madison, told news outlet Space.com: “It's important to explore these possibilities so that we have an idea of what all forms of life can look like, not just Earth life.” "One of the major reasons that origin-of-life researchers care about autocatalysis is because reproduction — a key feature of life — is an example of autocatalysis. “Life catalyses the formation of more life. One cell produces two cells, which can become four and so on. “As the number of cells multiply, the number and diversity of possible interactions multiplies accordingly.” The scientists searched in a huge trove of existing scientific documents for examples of autocatalysis, and found 270 different cycles of the reactions. Most of the 270 examples did not feature organic compounds, but rather elements which are rare in life forms such as mercury, or the radioactive metal thorium. “It was thought that these sorts of reactions are very rare,” Kaçar said in a statement. “We are showing that it's actually far from rare. You just need to look in the right place.” Now, it means scientists can test these cycles to get a better understanding of how autocatalysis can work. “The cycles presented here are an array of basic recipes that can be mixed and matched in ways that haven't been tried before on our planet,” said study author Zhen Peng, also an evolutionary biologist at the University of Wisconsin-Madison. “They might lead to the discovery of completely new examples of complex chemistry that work in conditions where carbon- or even silicon-based cycles are too either combusted or frozen out.” The scientists published their findings in the Journal of the American Chemical Society.

An influencer has been criticised for complaining about commuters getting in her way as she posed for photos in front of a tube on the London Underground. In the viral video from last year, TikToker Antonia Freya Lydia (@turnttoni) attempted to show off her black feather strapless dress in a clip but this proved to be challenging as people were walking along the platform. "Taking an aesthetic video in London Underground be like," she wrote in the on-screen text as people walked past and blocked her shot. She added in the caption: "Like can yoh wait just one sec,sir." @turnttoni like can yoh wait just one sec,sir? #fy #foryou #london #underground Since sharing the video, it went with 8.9m views where people took to the comment section and didn't hold back on their thoughts. One person said: "Some people actually use the station to get to places instead of taking insta photos crazy right?!?" "GIRL IT’S A TRAIN STATION—" another person wrote. A third person added: "You know people have to go to work and they're not going to stop their lives for you. Don't want people around, go someplace private." "If you were in a wide open space this would make sense but… in a TRAIN STATION?!" a fourth commented. Someone else replied: "Imagine doing this at Oxford Circus and expecting people to get out of your way." While a few defended the influencer too "Don’t think she knew it was gonna be that busy and she is probably joking lol," one person wrote. Someone else replied: "Idk about y’all but i understand her completely." But this wasn't the end of the matter... The debate was reignited when Twitter user @schizarella (not Antonia in the original video) weighed in with their thoughts after the clip was reposted on the platform on Sunday. "When you see someone recording just walk behind the camera or wait literally ten seconds, if you can't do this then you don't deserve to be part of a civilized society," they wrote in a post that has since become unavailable to view. It prompted many people to disagree and criticise the influencer for her actions - here are some of the comments. In a recent TikTok, Antonia aka the influencer in the original video responded to a critical comment saying they couldn't believe she was complaining about people getting in her shot, and called her content "lame." @turnttoni Replying to @sop excuse me, what do you mean? #fy #foryou #subway To which Antonia replied with a video filled with different snaps of herself all over the world and in different outfits where she seemed to be unbothered as she wrote: "wait.... lame?"
