A group of geologists has recently achieved a breakthrough in identifying potential sites for the formation of diamonds. Diamonds, the hardest naturally occurring material we have found, originate under the extreme conditions of immense pressure and high temperatures deep within the Earth's interior. These precious gems are occasionally pushed to the surface in molten rock formations known as kimberlite. However, there are currently two competing theories regarding what is responsible for this rush of kimberlite which brings diamonds to the surface. In a recent study, these theories were closely examined by a research team. In a piece for The Conversation study author and Associate Professor in Earth Science at the University of Southampton, Thomas Gernon explained: “one proposes that kimberlite magmas exploit the ‘wounds’ created when the Earth’s crust is stretched or when the slabs of solid rock covering the Earth - known as tectonic plates - split up.” “The other theory involves mantle plumes, colossal upwellings of molten rock from the core-mantle boundary, located about 2,900km [1,802] beneath the Earth’s surface.” However, neither of these theories adequately explains how magma manages to find its way through the Earth's crust, or the specific composition of the resulting kimberlite. By employing statistical analysis and machine learning, the team analysed the breakup of continents and its correlation with kimberlite formation. Their findings indicated that the majority of kimberlite volcanoes erupt 20 to 30 million years after tectonic breakup. “It also added a major clue,” Gernon explained. “Kimberlite eruptions tend to gradually migrate from the continental edges to the interiors over time at a rate that is uniform across the continents.” Delving deeper into their investigation through computer-generated models, the team ultimately concluded that diamond eruptions stem from a "domino effect." As continents gradually drift apart from each other, they generate rifts of thinned crust. As this happens, regions of thick, cold rock descend into the hot magma beneath, inducing an upsurge of the mantle, which in turn triggers a similar flow in nearby continents. Gernon elaborated on the team's findings, saying, "Various other results from our computer models then advance to show that this process can bring together the necessary ingredients in the right amounts to trigger just enough melting to generate gas-rich kimberlites,” Gernon explained. “Once formed, and with great buoyancy provided by carbon dioxide and water, the magma can rise rapidly to the surface carrying its precious cargo.” Moreover, the same methodology could potentially be employed to locate diamonds and other rare elements. “The processes triggering the eruptions that bring diamonds to the surface appear to be highly systematic,” Gernon siad. “They start on the edges of continents and migrate towards the interior at a relatively uniform rate.” The study is published in the journal Nature.

Chimpanzees are our closest relatives, so it’s not surprising that they can do many of the things that we can. They’re able to create tools and can even use sign language, plus they share 98.8 per cent of their DNA with humans. It is, therefore, no wonder that the question has often been asked: could humans and chimps ever produce offspring? The answer, according to one evolutionary psychologist, is yes – and it’s already happened. Gordum Gallup made the eyebrow-raising claims in an interview with The Sun Online back in 2018. He told the news site that a human-chimpanzee hybrid – which he dubbed a “humanzee” – was born in a Florida lab 100 years ago. And if you’re wondering how the scientists behind the experiment managed to keep it hushed up for decades, it’s because – according to Gallup – they swiftly killed the infant when they realised the implications of what they’d done. Gallup, a professor at New York’s University at Albany, said his former university teacher told him that the secret birth took place at a research facility in Orange Park, where he used to work. “They inseminated a female chimpanzee with human semen from an undisclosed donor and claimed not only that pregnancy occurred but the pregnancy went full term and resulted in a live birth,” the psychologist told The Sun. “But in a matter of days, or a few weeks, they began to consider the moral and ethical considerations and the infant was euthanised.” Putting Gallup’s unsubstantiated story to one side, it’s unclear whether a human-chimpanzee hybrid is even possible. Some experts believe that our human ancestors and chimpanzees may have been capable of interbreeding as late as 4 million years ago according to IFL Science, which notes that our last common ancestor lived 6-7 million years ago. However, the website also notes that this theory is widely contested. It also points out that other animals with similar genetic differences to that of humans and chimps, such as horses and zebras, have been able to reproduce. And yet, the offspring are often infertile. Nevertheless, back in the 1970s, plenty of people believed that a chimp called Oliver was a human-monkey hybrid thanks to his humanistic walk, intelligence and physical features (he was said to have a smaller, flatter face than his ape peers, according to Historic Mysteries). It wasn't until tests were conducted on Oliver in 1996 that the matter was finally settled: he had 48 chromosomes so was categorically not a humanzee but a regular chimp. Oliver The Humanzee www.youtube.com Still, one certainty is that scientists continue to tread an ethical tightrope when it comes to investigating chimps and their potential to further biomedical research. In 2021, scientists created the first (publicly documented) part-monkey, part-human embryo by growing human stem cells in a macaque monkey. The aim of the work, which was carried out at California’s Salk Institute, was to help create organs for transplants and improve our understanding of human development and disease progression. In 2020, a team of German and Japanese scientists spliced human genes into the brains of marmosets, resulting in the monkey fetuses having larger, more human-like brains, according to the study, which was published in the journal Science. Once the experiment was complete, the team destroyed their creations “in light of potentially unforeseeable consequences with regard to postnatal brain function”. One thing’s for sure, no scientist wants to find themselves the architect of a real-life Planet of the Apes. Sign up for our free Indy100 weekly newsletter Have your say in our news democracy.

We don’t want to alarm anyone, but the sun is broken. A section of the sun has left the surface and begun circulating around the top of the star as if it were a huge polar vortex, and it’s not exactly clear why it’s happened. The observation was made possible thanks to the James Webb Space Telescope, and its no surprise that it piqued the interests of scientists everywhere. Tamitha Skov is a space weather physicist who regularly shares updates on social media, and she seemed incredibly excited about the latest developments. Sign up for our free Indy100 weekly newsletter “Talk about Polar Vortex! Material from a northern prominence just broke away from the main filament & is now circulating in a massive polar vortex around the north pole of our Star,” she wrote. “Implications for understanding the Sun's atmospheric dynamics above 55° here cannot be overstated!” Solar prominences consist of hydrogen and helium, and they extrude from the sun’s service releasing plasma. While there’s confusion around the cause of the phenomenon, it could be related to the reversal of the sun’s magnetic field, as well as the fact that something expected has been known to happen when the sun reaches a 55 degree latitude in every 11-year solar cycle. Solar physicist Scott McIntosh, who is the deputy director at the National Center for Atmospheric Research in Boulder, Colorado told Space.com: "Once every solar cycle, it forms at the 55 degree latitude and it starts to march up to the solar poles. “It's very curious. There is a big 'why' question around it. Why does it only move toward the pole one time and then disappears and then comes back, magically, three or four years later in exactly the same region?"

Have you always wanted to be able to do the splits or a backflip? Maybe you’ve watched your kids do a gymnastics class and thought, ‘Wow, that looks so fun’. Adult gymnastics is gaining some serious popularity online, with the TikTok hashtag #adultgymnastics getting over 209.5 million views. Influencers such as Anna Archer – who has over 300,000 followers on Instagram and creates content surrounding lots of different fitness experiments – and stunt woman Corinne Nicewick have shared clips of their experiences of trying out gymnastics as an adult. Nicewick, despite being a talented stuntwoman, has shared clips of how challenging she has found the sport, with viewers finding her attempts both funny and encouraging. Gymnastics has put some famous faces in good stead for other fitness-related challenges, with gymnast Beth Tweddle winning the 2103 series of Dancing on Ice and Ellie Downie, GB gymnast taking on the gruelling SAS: Who Dares Wins reality show in 2023.So, what do you need to know before you get involved? How does adult gymnastics work? Can anyone do it? Classes have been steadily cropping up across the UK encouraging adults of all abilities to get involved in gymnastics, and unless you have a health problem or injury that may restrict you from doing so, anyone can get involved. It is not so dissimilar to exercises you may already do like plyometrics (explosive body weight resistance exercises like box jumps), CrossFit or yoga. “Gymnastics is a series of different exercises that test your strength, mobility, flexibility and agility,” says Sofia Zolobova, instructor and gymnastics expert at Gymbox. “It’s also a lot of fun, incorporating lots of different floor, beam and hoop exercises,” she explains. This element of variety can bring a more fun, playful element to your workout routine. What are the health and wellbeing benefits of adult gymnastics? Gymnastics will give your body a really different workout and improve your strength, mobility and balance. “Strength and mobility are both very important as we grow older,” says Zolobova. “Gymnastics uses your own body weight, so not only do you get stronger, you move better. For example, to be able to execute a hand stand you need great shoulder mobility,” she explains. “With our modern tight shoulders, gymnastics can be helpful in improving our posture.” How do you get past being scared? As a kid, doing a cartwheel and taking a tumble doesn’t seem so threatening, but as adults we are all a bit more scared of getting hurt. Instead of falling into the trap of fear, embrace the playfulness of it. Zolobova says: “It’s a really fun way to exercise. It includes handstands, cartwheels and frog jumps, letting you unleash your inner child. It empowers you to do cool tricks as an adult and work up to a certain goal. It’s also a great fear fighter – sometimes you just have to let go and trust yourself.” What should we be careful of in adult gymnastics? Your fitness and flexibility may not progress as quickly as they might have done as a child. “Children are naturally more flexible than adults, so when undertaking gymnastics for the first time keep this in mind. Take things slow and one step at a time – you can always build up strength and flexibility with consistent practice,” explains Zolobova. How do we protect our backs and joints? Putting your back out or hurting your joints is a very real fear as an adult. Zolobova says: “Stretching should never be skimped on and should be thorough and dynamic [involving movement]. It’s also very important to make sure the body is warmed up before undertaking any gymnastic moves, a light jog and jumping jacks are great ways to get the muscles warm fast.”

Scientists have theorised that if we are going to find life on Mars, it will be microbes and they will be living in caves below the surface. The Perseverance rover, NASA’s exploration robot on the Red Planet, is currently searching for signs of ancient life in the Jezero Crater. Scientists already know that there are so-called lava tubes on Mars, which some think could be large enough to shelter the first human astronauts from the cosmic radiation which is bombarding the planet. When these were formed, they thought conditions on Mars were more similar to those on Earth, with flowing water, an atmosphere and a warmer climate. One theory is that as conditions changed on the surface and Mars lost its magnetic field and atmosphere, life could have shifted underground. Daniel Viúdez-Moreiras from Spain’s National Institute for Aerospace Technology calculated that UV radiation levels would be about 2 percent of the radiation levels found at the surface. Fortunately, we have lava tubes here on Earth too, which could tell us what life could look like in similar conditions elsewhere in the Solar System. Hawai’i’s Mauna Loa volcano lava tubes were recently explored by NASA. Within them, life is sheltered from conditions on the surface. On Earth, that is a bad thing: we have sunlight and oxygen. But on Mars, where conditions are much harsher, that is a big advantage. “The microbes we found in Hawaii could be similar to microbes that once lived on Mars,” researcher Chloe Fishman explained to NASA following a trip to collect samples in April, “or even microbes that live there today.” The team brought back samples from the cave so as to sequence the genomes of the microbes they found there. And there are already plans to explore lava tubes on the Moon, too. So maybe, just maybe, they will hold the secret to life on Mars.

A 20-year-old has swapped veganism for raw meat, eating uncooked items including beef, chicken, heart and liver on a daily basis for the past four years, and claims he has “never gotten sick”. Jones Hussain, from Stockholm, Sweden, has eaten raw chicken as well as raw cuts of beef, minced meat and fish, without batting an eyelid – even if they are brown or smell slightly. He says he would happily eat any kind of meat provided it is good quality, from “wild boar to camel” but that he prefers minced beef because it is cheap, accessible and does not smell compared with chicken. Jones took the decision to eat raw meat just a few months after quitting veganism in 2019 “in the name of health” after he watched a YouTube video with the late American alternative food nutritionist, Aajonus Vonderplanitz, whose “Primal Diet” has inspired people worldwide. Health has always been important for Jones, who supplements his raw meat diet with fruit and juiced vegetables. He said he would not eat cake for £10,000 because of the sugar and claims to have not had a slice since the age of 13. “If any food safety expert looked at the food I eat, I think they would have a heart attack because the beef is sometimes brown, the liver looks green, the chicken stinks,” Jones told PA Real Life. “But I eat that and then nothing happens. “I did the experiments on myself to see whether what we have been led to believe is actually true and surprise, surprise, it wasn’t.” Jones, who said he has always been driven by “health”, came across the raw meat diet plan in 2019 a few months after quitting veganism. “My starting point has always been health,” he said. “So I’ve experimented with a bunch of things in the name of health.” The diet was designed by Vonderplanitz, who touted the benefits of eating raw foods, in particular meat and dairy. “I found one of his lectures on YouTube and started listening,” he said. “At first, I was just as shocked as anyone would be to see someone eat such a diet.” But Jones said he found Vonderplanitz’s arguments to be “honest and convincing” and so decided to give it a try. “I ate raw meat for the first time in November 2019 and I felt great,” he said. “It was just a straight cut of raw beef.” Having not fallen ill, Jones then decided to try raw ground beef. “That was the scary part because that’s when you enter into uncharted territory,” he said. “I was like, if I get sick then I won’t do this anymore. “Lo and behold, again, I didn’t get sick, so I started eating raw ground beef because it’s much cheaper than straight cuts.” To start with, Jones would flavour the raw meat with spices and garlic. “But then I felt that I didn’t need them, even from a taste perspective,” he said. “So I just started consuming it by itself and ever since then I’ve eaten raw ground beef almost every day.” By the summer of 2020, Jones had become accustomed to eating all types of meat. “I had no problems eating raw chicken because I had found a fairly good source in the supermarket so I ate it like KFC,” he said. “I also started buying raw liver here and there, and eating a small amount every day.” The raw meat Jones kept in his fridge soon started to turn “green”, but this did not stop him from eating it. “Since I was so convinced about what Aajonus was saying, I was not worried and just consumed it,” he said. “But if there was any white mould, then I got rid of the batch, although this did not happen very often.” Jones has continued eating raw meat ever since, although his family prefers ground beef to chicken because of the smell. “Nowadays I don’t so much eat raw chicken because it stinks up the house,” he said. In a single sitting, Jones said he is capable of consuming around 400g of raw liver. He said he believes dumping veganism for raw meat has improved his gut health and helped get rid of his acne. “The thing with raw meat is that the nutrients are more easily absorbed and unaltered,” he claimed. “It’s not that raw meat has some kind of special super power, it’s just that by not cooking it, I get more nutrients and no byproducts.” NHS guidelines, however, state that “cooking meat properly” kills harmful bacteria which can cause food poisoning. Jones had been a vegan for two years, from 2017 to 2019, before eventually converting to the primal diet. “It’s not that I was struggling to get enough nutrients,” he said. “It’s that a human being cannot survive on a vegan diet successfully. “Of course you can take supplements but it’s not the same thing, because they are processed. “There is no other way of getting these nutrients naturally other than by eating animal products. “So veganism on that basis, falls on its face.” Jones also eats raw fish such as salmon and tuna and said he is happy to eat any type of meat provided he can find a reliable supplier. The Primal Diet also includes fruit and vegetables, all of which are consumed raw. “I eat cucumbers and tomatoes, as well as oranges and apples when they are available to me,” he said. “The philosophy is don’t cook the food, but there is a variety.” Jones’ unusual diet often shocks people, including his parents who are concerned for his wellbeing. He explained: “Usually people have the same reaction, at first they think what the hell is this guy doing? He’s going to die in a few days. “Then they speak to me and find out that I’ve been doing it for three and half years, that I’ve never gotten sick, that my arguments are logical and that I look healthy. “They are like all right, that’s a new perspective that I had not heard before.” People behave differently on social media, however, said Jones, who has his own YouTube channel, Excellent Health. He also works part time at an elderly day care centre and has written a book titled The 6 Health Commandments. “The only time I ever got food poisoning was from a frozen bag of raspberries before I started eating meat,” he said. “I decided not to act out of fear, but to see what is true and what isn’t true.” To find out more about food safety, visit www.food.gov.uk/safety-hygiene/cooking-your-food.

When it comes to approaching someone you like at a bar, it may be more a case of alcohol giving you liquid courage than “beer goggles”, researchers say. A new study suggests drinking alcohol makes people more likely to approach someone they already find attractive, but does not make others appear more attractive. Some people argue that intoxication makes others seem better-looking – but according to the researchers, this has not been systematically studied. Past research typically had people simply rate others’ attractiveness while sober and while intoxicated based on photos. But the new study added the possibility of meeting the people being rated. The study, led by Molly Bowdring of the Stanford Prevention Research Centre, Stanford University, in the USA (affiliated with University of Pittsburgh at the time of this study), and her dissertation adviser, Michael Sayette, involved 18 pairs of male friends in their twenties. The men were brought to the laboratory to rate the attractiveness of people they saw in photos and videos. They were also told that they may be given the chance to interact with one of those people in a future experiment. After the ratings were given, the men were asked to pick those who they would most like to interact with. Pairs of men visited the lab on two occasions – on one occasion they both received alcohol to drink – up to about a blood alcohol concentration of .08 per cent, the legal limit for driving in England, Wales and Northern Ireland, and the United States, and on the other occasion, they both received a non-alcoholic drink. Friend pairs entered the lab together in order to mimic social interactions that would typically take place in a real drinking situation. The researchers say they did not find evidence of beer goggles – whether or not the men were intoxicated had no effect on how good-looking they found others. Professor Sayette, from the University of Pittsburgh, said: “The well-known beer goggles effect of alcohol does sometimes appear in the literature, but not as consistently as one might expect.” However, according to the findings, drinking alcohol may affect how people react to those they find attractive in a different way. The researchers found it impacted how likely the men were to want to interact with people they found attractive. When drinking, they were 1.71 times more likely to select one of their top-four attractive candidates to potentially meet in a future study compared with when they were sober. The researchers suggest alcohol may not be altering perception but rather enhancing confidence in interactions, giving the men liquid courage to want to meet those they found the most attractive. According to the researchers, the findings could have implications for therapists and patients. Prof Bowdring said: “People who drink alcohol may benefit by recognising that valued social motivations and intentions change when drinking in ways that may be appealing in the short term, but possibly harmful in the long term.” The findings are published in the Journal of Studies on Alcohol and Drugs.
