Visual Glitch Leads To Accidental Discovery Of Spiral In Mysterious Oort Cloud

Scientists have long assumed the Oort Cloud, one of the most mysterious structures in our solar system, to be spherical. But during the pre-production of their new space show, "Encounters in the Milky Way," they noticed a strange spiral pattern in the middle of the cloud.
The show, which premiered on Monday at New York City's Hayden Planetarium, featured a computer-generated visualisation of the Oort Cloud on the dome. The team was reviewing the animation when they noticed what appeared to be a spiral structure inside the typically spherical cloud shape.
It immediately attracted the attention of astronomers and animators, despite not being a part of the project and only happening by chance. The structure surprised the scientists as it looked like a spiral galaxy like ours.
Jackie Faherty, an astrophysicist at the American Museum of Natural History and the curator of the show said, "We hit play on the scene, and immediately we saw it. It was just there. I was confused and thought that was super weird. I didn't know if it was an artefact; I didn't know if it was real," as per CNN.
During the investigation, David Nesvorny, an institute scientist with the Southwest Research Institute in Boulder, Colorado, and the Oort Cloud expert said he initially thought the spiral pattern might just be a mistake in the animation. When he rechecked, he found the spiral was real and it wasn't just a glitch. He was surprised to know about this, as he had never noticed it before.
Mr Nesvony published a scientific paper in April, "The Astrophysical Journal," saying, "Weird way to discover things... I should know my data better after years of working with it."
He explained that the spiral shape in the Oort Cloud happened because of the galactic tide. Although the Sun's gravity controls everything in our solar system, the Oort Cloud is so far away from the Sun that its gravity becomes weaker and it starts to affect the objects there.
So, instead of pulling them straight, it twists the way they orbit, giving it a spiral pattern look. The spiral pattern could help scientists better understand how solar systems form and evolve over time.

Scientists Recreate Face Of 10,500-Year-Old Woman Using DNA

Researchers at Ghent University have reconstructed the visage of a pale, dark-haired, blue-eyed prehistoric woman who lived 10,500 years ago in what is now Belgium. They produced an amazing image, depicting the face of a woman who lived and died in the Meuse River valley, using ancient DNA. In 1988, the remains of the Mesolithic woman were found in the Margaux cave, which is close to Dinant. She was a hunter-gatherer from Western Europe, the same group as the popular Cheddar Man from Great Britain. DNA studies showed the Margaux woman's eyes were blue, just like Cheddar Man's. She did, however, have a somewhat lighter complexion than the majority of other Mesolithic individuals in Western Europe examined so far. It is a minor but crucial detail, according to the project's lead geneticist, Dr. Maite Rivollat. The reconstruction of her face and living conditions was made possible by a mix of anatomical, genetic, and archaeological data. Ghent University archaeologist Isabelle De Groote told CNN that the 'Meuse Woman' was from the same ethnicity as the Cheddar Man, who lived in what is now the United Kingdom at the time, but had a lighter complexion. "We could also infer from the skull that she was between 35 and 60 years old," De Groote told CNN. The prehistoric Belgian woman also resembled Cheddar Man with a prominent nasal bridge. "She also has noticeable brow ridges, even though she's a woman," De Groote added. University archaeologist Philippe Crombe said that "quite good quality" DNA was extracted from the woman's skull so that "a very detailed reconstruction" could be made. While some of her features, like her jewellery and tattoos, are based on archaeological data gathered from previous digs in the River Meuse basin, helping researchers create a picture of the woman's daily life — her complexion, hair, and eyes are all based on ancient DNA. The creative team also used archaeological evidence, such as tools, shells, paints, and camp remnants. This made her world come to life, along with her face. Every detail was meticulously recreated, from hunting methods to transportation, from plants to animals. The remains of the 'Meuse Woman' were discovered in the Margaux cave in Dinant in 1988-1989, along with the remains of eight other women. This was "an unusual finding" because the majority of Mesolithic burial sites include a mix of men, women, and children. The reconstruction was carried out in cooperation with Dutch artists Kennis and Kennis and researchers from the ROAM project (a Regional Outlook on Ancient Migration), an interdisciplinary effort comprising archaeologists, bioanthropologists, geneticists, and artists.

New study claims parents must worry about ‘addictive use' more than screen time

Parents worldwide remain worried about the number of hours children remain glued to their mobile screens in a day. Now, a new study suggests that longer screen time at age 10 is not associated with higher rates of suicidal behavior. What mattered more is whether the children are getting addicted to their screens or not. The research, published on Wednesday in JAMA journal of the American Medical Association states that the time children spent on social media and video games was not associated with internalizing symptoms of mental health problems (anxiety and depression), CNN reported. The study covered more than 4,000 children across the US over a period of four years, with the participants being in the 9-10 years age group at the beginning, CNN reported. Also read: Trump Mobile: All about president's new mobile service and gold 5G phone The authors found that children, who remain at higher risk for suicidal behaviors, were the ones who told them that their use of technology become 'addictive' over time, The New York Times reported. ( Lead study author Yunyu Xiao, associated with the Weill Cornell Medical College in New York, dubbed addictive use as 'excessive use' which further interferes with home responsibilities, schoolwork and other activities. The ones addicted had a "craving for it and cannot stop using it," the assistant professor said. During the study, this addictive behavior was found to be very common among children, especially in terms of mobile phone usage, where almost half of them had high addictive use. Also, more than 40 per cent were on a high trajectory of addictive use for video games. The study warns that children with high or increasing use of social media and mobile phones were two to three times as likely as other kids to have suicide thoughts or harm themselves. Yunyu Xiao said this was the first study to find out that "addictive use is important, and is actually the root cause, instead of time'. The research asks parents to help prevent screen addiction in their children. For this, kids should be made aware about times when they should use cell phones, video games and other things. Psychologist Jean Twenge said children should be kept away from social media until they turn 15, while parents should avoid giving them internet-enabled phones for as long as possible. In 2023, Gallup reported that US teens were spending 4.8 hours on an average per day on YouTube, TikTok and Instagram.
