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.

Microsoft has been given a non-voting observer seat on OpenAI’s board, following the official return of Sam Altman as the ChatGPT company’s chief. OpenAI reached a deal to have Mr Altman back as the company’s chief executive, just days after it abruptly fired him. Mr Altman said he was looking forward to returning to OpenAI with the support of Microsoft chief Satya Nadella. “Sam Altman is back as CEO, Mira Murati as CTO and Greg Brockman as President. OpenAI has a new initial board,” OpenAI posted on Thursday on X. “I have never been more excited about the future. I am extremely grateful for everyone’s hard work in an unclear and unprecedented situation, and I believe our resilience and spirit set us apart in the industry,” Mr Altman said in a memo to employees. The addition of Microsoft, which has heavily invested in OpenAI, to its board as a non-voting observer means the software giant will get more access to view the company’s progress. It will, however, not have an official vote on its decisions. Mr Altman’s return also resolves some of the uncertainties around the non-profit company and its leadership. “The best interests of the company and the mission always come first. It is clear that there were real misunderstandings between me and members of the board,” the returning chief said in his memo. “For my part, it is incredibly important to learn from this experience and apply those learnings as we move forward as a company,” he said. “I welcome the board’s independent review of all recent events.” With three of the board members who ousted Mr Altman now gone, the company said its new board will consist of former Salesforce co-chief Bret Taylor, who will be OpenAI chairman, former treasury secretary Larry Summers and Quora boss Adam D’Angelo. OpenAI co-founder Ilya Sutskever, who voted to remove Mr Altman and later changed position to push for his return, will also exit the board, the company said. Greg Brockman, who quit the company amid the chaos last week, is returning to his previous role as the company’s president, OpenAI said. “Our research roadmap is clear; this was a wonderfully focusing time. I share the excitement you all feel; we will turn this crisis into an opportunity,” Mr Altman told employees.

Instagram posts are appearing elsewhere – without the knowledge of the people posting them, and with no way for them to stop it once they do find out. Users of the company’s new Instagram Threads app are finding that their posts are being automatically pushed into their Facebook feeds. The company said that it was “listening” to complaints from users who did not want their posts appearing on Facebook. But it does not appear to be offering a way for people to stop it happening. Meta has often used its various platforms to promote other ones. New apps and features have often been shown in the Facebook news feed especially, as the company looks to introduce them to other users. Facebook has long shown posts from Instagram Reels, for instance. And companies on WhatsApp can buy ads that show on Facebook. The new behaviour means that people loading up their Facebook news feed may see posts that their friends have put on Instagram Threads. Users complained that the behaviour was unwanted, however. “How do I keep my Threads from showing up on Facebook? I want [them] separate and I don’t want my Threads randomly showing up on Facebook in someone’s “for you” or any place else,” one user wrote in response to the company. In response, it confirmed that it had made the change but did not appear to suggest it would be changed. The update was intended “to make it easier for people to see the latest content from Threads directly on Facebook and Instagram”, it said, but it is “listening to feedback like yours as we continue to build on this”. Author and YouTuber Hank Green was one of many who pleaded with the company to go back to keeping posts on the various apps separate. “It’s really true that threads and Facebook have very different cultures and I choose specifically what I want to go where. For other people, that can actually be a little unsafe. Let people opt out. Next time, build that first. Move slow, fix things. We’re doing good here,” he wrote in response to the official Threads account.
