Mysterious yellow glass found in Libyan desert 'caused by meteorite', say scientists
Mysterious yellow glass found in Libyan desert 'caused by meteorite', say scientists
A meteorite which smashed into earth 29m years ago may be behind a strange yellow glass found in a certain part of the desert in southeast Libya and southwestern Egypt, according to researchers. The Great Sand Sea Desert stretches over about 72,000 square kilometres across the two countries, and is the only place where the mysterious yellow material is found on Earth. Researchers first described it in a 1933 scientific paper, calling it Libyan desert glass. Mineral collectors have long valued it for its beauty and mysterious qualities – and it was even found in a pendant in Egyptian pharaoh Tutankhamun’s tomb. The origin of the glass has been a mystery for centuries, but researchers writing in the journal De Gruyter used new advanced microscopy technology to get answers. Elizaveta Kovaleva, a lecturer at the University of the Western Cape, wrote that the glass was caused by “the impact of a meteorite on the Earth's surface”. Writing in The Conversation, she said: “Space collisions are a primary process in the solar system, as planets and their natural satellites accreted via the asteroids and planet embryos (also called planetesimals) colliding with each other. These impacts helped our planet to assemble, too.” She said: “We studied the samples with a state-of-the-art transmission electron microscopy technique, which allows us to see tiny particles of material – 20,000 times smaller than the thickness of a paper sheet. “Using this super-high magnification technique, we found small minerals in this glass: different types of zirconium oxide (ZrO₂).” One of the types of this mineral found in the glass can only form at temperatures between 2,250 celsius and 2,700 celsius. Toasty. Kovaleva said: “Such conditions can only be obtained in the Earth's crust by a meteorite impact or the explosion of an atomic bomb.” However, she wrote, there are just as many questions as there are answers. The nearest known meteorite craters are too far away and too small to be the cause of that much glass all concentrated in one part of the world. “So, while we've solved part of the mystery, more questions remain. Where is the parental crater? How big is it – and where is it? Could it have been eroded, deformed or covered by sand?” Safe to say, the scientists will keep on looking until they have the answers.

Crime victims’ data revealed by two police forces in FoI responses
Crime victims’ data revealed by two police forces in FoI responses
The personal data of more than 1,000 people, including victims of crime, was included in Freedom of Information (FoI) responses issued by Norfolk and Suffolk Police, the forces have said. In a statement, the two East Anglian constabularies said a “technical issue” meant raw crime report data was included in a “very small percentage” of FoI responses issued between April 2021 and March 2022. It is the latest data breach involving police responses to FoI requests, coming after the Police Service of Northern Ireland published a document which included the names and other details of around 10,000 officers and staff. A joint statement said: “Norfolk and Suffolk Constabularies have identified an issue relating to a very small percentage of responses to Freedom of Information (FOI) requests for crime statistics, issued between April 2021 and March 2022. “A technical issue has led to some raw data belonging to the constabularies being included within the files produced in response to the FOI requests in question. The data was hidden from anyone opening the files, but it should not have been included. “The data impacted was information held on a specific police system and related to crime reports. The data includes personal identifiable information on victims, witnesses, and suspects, as well as descriptions of offences. It related to a range of offences, including domestic incidents, sexual offences, assaults, thefts and hate crime. “A full and thorough analysis into the data impacted has now been completed, and today we have started the process of contacting those individuals who need to be notified about an impact to their personal data. “This will be done via letter, phone, and, in some cases, face to face, depending on what information was impacted and what support is required. “We expect this process to be complete by the end of September. We will be notifying a total of 1,230 people whose data has been breached.” The data watchdog the Information Commissioner’s Office (ICO) is investigating. Stephen Bonner, deputy commissioner at the ICO, said: “The potential impact of a breach like this reminds us that data protection is about people. It’s too soon to say what our investigation will find, but this breach – and all breaches – highlights just how important it is to have robust measures in place to protect personal information, especially when that data is so sensitive. “We are currently investigating this breach and a separate breach reported to us in November 2022. “In the meantime, we’ll continue to support organisations to get data protection right so that people can feel confident that their information is secure. “If you’re concerned about the way your information has been handled, you can get advice on what to do from our website.” Read More Charity boss speaks out over ‘traumatic’ encounter with royal aide Ukraine war’s heaviest fight rages in east - follow live Police chief calls for parents to be held accountable over social media crazes Hackers ’emptied’ victims’ accounts and tried to blackmail GTA maker, court told AI can predict Parkinson’s subtype with up to 95% accuracy, study suggests

Apple to stop using leather in iPhone, Apple Watch and all new products
Apple to stop using leather in iPhone, Apple Watch and all new products
Apple will stop using leather, it has announced. It will offer no new products using materials taken from animals, it said. That includes iPhone cases and Watch bands, both of which make heavy use of leather. Lisa Jackson, Apple’s vice president of environment, policy and social initiatives, noted that leather is a popular material for accessories. But it has considerable environmental impact, she noted, especially at the scale that Apple uses it. As such, it has committed to phasing out those materials. Instead, it will rely on new materials that have been especially developed. For the Apple Watch’s sport loop, for instance, it has changed the material to use 82 per cent recycled yarn. For the straps that are currently made out of leather, it will rely on a new seemingly custom developed material called “FineWoven”. That will presumably also be used for the cases made for the new iPhone 15. And Apple has developed new straps with Nike and Hermès. The latter collaboration has relied heavily on leather – but recently Apple has been rumoured to be selling off those products cheaply. The new materials will help make the new Apple Watch Series 9 the first carbon neutral product the company has made.

Black Mirror creator Charlie Brooker shares the 's***' episode idea ChatGPT came up with
Black Mirror creator Charlie Brooker shares the 's***' episode idea ChatGPT came up with
A lot of things in the chaos that is life have sparked comparisons to Netflix’s dark anthology series Black Mirror over the years. Its very first episode back in 2011 - “The National Anthem” – resurfaced in 2015 amid ‘Piggate’ and David Cameron, Apple’s Animojis drew parallels with the titular animated bear in “The Waldo Moment”, and just this week people thought Apple’s first AR headset looked particularly dystopian. Now, as both tech experts and political advisers warn of the threat of artificial intelligence (AI), and the AI chatbot ChatGPT continues to generate memes and news stories online, Black Mirror’s creator Charlie Brooker has revealed he’s had a go with the software – albeit with underwhelming results. He told Empire: “I’ve toyed around with ChatGPT a bit. The first thing I did was type ‘generate Black Mirror episode’ and it comes up with something that, at first glance, reads plausibly, but on second glance, is s***. “Because all it’s done is look up all the synopses of Black Mirror episodes, and sort of mush them together. Then if you dig a bit more deeply you go, ‘oh, there’s not actually any real original thought here.’” Shame – that would have been suitably meta. Brooker did, however, note some learnings from his experience with the chatbot, adding: “I was aware that I had written lots of episodes where someone goes, ‘oh, I was inside a computer the whole time!’ So I thought, ‘I’m just going to chuck out any sense of what I think a Black Mirror episode is.’ Sign up to our free Indy100 weekly newsletter “There’s no point in having an anthology show if you can’t break your own rules. Just a sort of nice, cold glass of water in the face.” Although an AI-produced episode of Black Mirror is off the cards for now, fans of the show do have five new ones to look forward to when the hotly anticipated season six drops on Netflix on 15 June. Opening episode “Joan Is Awful” features a Netflix parody known as Streamberry in scenes akin to The Truman Show (and stars Scott Pilgrim actor Michael Cera and comedian Rob Delaney), episode two titled “Loch Henry” is reported to have elements of past episode “White Bear” in it, and Breaking Bad’s Aaron Paul is up in space in “Beyond The Sea”. Meanwhile the penultimate episode “Mazey Day” appears to follow the scandal-hit celebrity in its title, and stage stars Anjana Vasan and Paapa Essiedu round off the series with “Demon 76” – a story which is reportedly about a sales assistant forced to do awful things.
