The makers of the latest in the stealth action series have put Arabic front and centre of the project.

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.

The formula for the perfect fish finger sandwich has been revealed: it's made with four fish fingers, 'real' butter, two slices of white bread, ketchup... and cut sideways.  A poll of 2,000 adults who eat fish finger sandwiches found that 42 per cent said it was their sandwich of choice.  According to those polled, the optimum fish finger sarnie is also made with lettuce (21 per cent), cheese (15 per cent) and tomato (12 per cent).  Nearly half (43 per cent) like their sandwich to be cut sideways, so there are whole fish fingers on both sides of the bread. But 30 per cent like to cut their sarnie lengthways, so all fish fingers are in half, and nine per cent go as far as cutting everything into triangles. Commissioned by Birds Eye, The Marine Stewardship Council (MSC), and Iceland Foods, which sells MSC certified products like Birds Eye fish fingers, the study found 76 per cent would opt for a fish finger sandwich made from sustainably sourced cod.  A spokesperson for the supermarket chain said: "We know our fish fingers are not only great value, but they taste good too - making them a quick and easy meal that is guaranteed to be a crowd pleaser for families. "With one third of the world's fish stocks overfished, it is more important than ever for shoppers to choose seafood from sustainable sources." Exactly nine in 10 said the fish finger sandwich is a quick, easy and affordable meal that tastes good. In addition, just over two thirds (68 per cent) said they care about making mealtimes more sustainable. But 62 per cent claim they only have a vague idea of what sustainable fishing is. Encouragingly, 80 per cent correctly believe the process of sustainable fishing ensures fish are left in the ocean, impact on habitats and ecosystems is minimalised, and fisheries are effectively managed. However, one in 16 mistakenly think sustainable fishing happens once a year so there is enough fish left in the ocean for everyone else. When asked to describe the meaning of the blue MSC label, 42 per cent were “unsure”. However, 44 per cent rightly said it is the symbol of sustainability for wild-caught fish and seafood. More than half (55 per cent) said they care about the impact their food choices have on the planet but find it confusing, while 39 per cent of those who took part in the OnePoll.com study simply can’t afford to make the necessary changes. A spokesperson for MSC said: "The creators of the fish finger, Birds Eye, helped to co-found the MSC to help protect seafood supplies. While Iceland, who won MSC UK Newcomer of the Year in 2020, has made great progress in increasing the availability of sustainable seafood to its customers. "And now offers the highest percentage range of MSC certified wild seafood among all UK retailers.” A spokesperson for Birds Eye added: “We are very proud to be working closely with the MSC. Fish is good for our health, and so for the good of our oceans the Birds Eye fish range is 100 per cent MSC certified to make sure future generations can enjoy fish too.” SWNS Read More Order a bagel and schmear at Feltz Bagels, and you'll be fed an original piece of art Kale, crispy bacon upgrades grilled cheese to an adult level Six healthy recipes that both you and your gut will love Being vegetarian may partly be in one’s genes, study finds Jamie Oliver says he’d choose anonymity over fame if given the choice again

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.
