Scientists shed surprising new light on the Earth's 'butter-like' inner core
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.

Brighton boss explains ‘big, big celebration’ and says no disrespect was meant
Brighton boss Roberto De Zerbi made no apology for celebrating his side’s 3-2 win at Nottingham Forest like they had won the Champions League final. De Zerbi sprinted straight to the away fans at the City Ground, without shaking counterpart Steve Cooper’s hand, after his side ended a six-game winless run in a drama-filled Premier League encounter. The Seagulls looked primed for an easy three points after a tidy finish from Evan Ferguson and Joao Pedro’s double, the second from the penalty spot, put them 3-1 up after Anthony Elanga’s early goal for Forest. But the complexion of the game changed when VAR advised referee Anthony Taylor to give Forest a penalty, with Brighton skipper Lewis Dunk seeing red for his over-zealous protest. Morgan Gibbs-White scored from the spot but Forest could not find a leveller and Brighton held on for a much-needed win, which moves them into the top seven. “I want to explain our celebration, it wasn’t disrespectful to the opponent because I am used to living inside of football, but we are suffering a lot with injuries, we lost two players in the first half, we suffered a red card, we lost two points in the last games against Sheffield United and Fulham, the last win in the Premier League was at the end of September. “We are suffering a lot because it is one of the toughest times in my career. It was a big, big celebration. “We are very happy and I am very proud of the character and attitude we showed in a very tough moment. Without 10 players if Brighton can compete in two competitions, seventh in the league, and in the Europa League with Ajax, AEK Athens and Marseille, it is difficult. “We celebrated it like the final in the Champions League, it was not the Champions League, but the way we won the game with 10 players without the captain was excellent.” Dunk received a straight red card for foul and abusive language following Taylor’s decision to award Forest a penalty, which came 21 seconds after he was booked for encroaching while Taylor checked the VAR monitor. De Zerbi admitted Dunk apologised to his team-mates but will not face any internal disciplinary action. “I have not spoken yet with Lewis, he is a good guy, maybe he made a mistake,” De Zerbi added. “For me the situation is not clear. We have to accept the referee’s decision. “I always accept the referee’s decision. Dunky is a fan of Brighton, he is not a simple player. We can understand his emotion and his mistakes. “I don’t like rules. I am not a policeman, I am coach. He said sorry to everyone, he has understood his mistake.” Forest boss Cooper said would have liked the opportunity to shake De Zerbi’s hand at full-time. “I have not seen him. I don’t want to get into that, to be fair,” he said. “If you ask me I am a British coach, I have been brought up in always shaking hands after games and showing respect and trying to win and lose with dignity. “I am not saying he has not done that, you’ll have to ask him. If you ask me about what I will do, I will always shake hands. “But I understand that elsewhere it is a bit different. That is how it is.” Read More Bournemouth boss Andoni Iraola full of praise for two-goal Marcus Tavernier Joe Root joins England captain Ben Stokes in skipping next Indian Premier League Ding Junhui defies illness to defeat defending champion Mark Allen in York No cause for a party, Rob Edwards warns Luton after victory over Palace West Ham defeat is toughest one to take yet – Burnley boss Vincent Kompany Jonathan Obika’s last-gasp equaliser earns Motherwell point at Celtic
