A mysterious new set of stars has been detected by Nasa’s James Webb Space Telescope, which could shed new light on dark matter. Dark matter remains one of the most hotly debated elements in our solar system, and the new objects could change the way it is studied. Scientists believe the huge, newly-discovered stars are powered by illusive dark matter and shared their findings in the journal PNAS. “Discovering a new type of star is pretty interesting all by itself, but discovering it’s dark matter that’s powering this – that would be huge,” said study co-author Katherine Freese from The University of Texas in Austin. Sign up to our free Indy100 weekly newsletter The dark stars, known as JADES-GS-z13-0, JADES-GS-z12-0 and JADES-GS-z11-0 – were first identified as galaxies last December. It’s thought that they existed about 320-400 million years after the Big Bang, making them some of the earliest objects ever seen. The nature of dark matter continues to fascinate and mystify the scientific community. It’s believed that it could be formed by a new type of undiscovered particle, and the theorised component of the universe does not absorb, reflect or emit light. It’s also thought that suspected dark stars like these could explain a potential anomaly surrounding the number of large galaxies in the early universe. Currently, there are too many to fit the predictions of the theories surrounding the origins and the future of the universe. “It’s more likely that something within the standard model [of cosmology] needs tuning, because proposing something entirely new, as we did, is always less probable,” Dr Freese said. “But if some of these objects that look like early galaxies are actually dark stars, the simulations of galaxy formation agree better with observations,” she explained.

Microsoft has hired OpenAI co-founder and former chief executive Sam Altman just days after he was ousted from his company. Mr Altman was fired on Friday, less than a year after launching the hugely successful AI chatbot ChatGPT, with OpenAI’s board saying it “no longer has confidence in his ability to continue leading OpenAI”. Microsoft CEO Satya Nadella was reportedly “furious” about being blindsided by Mr Altman’s firing, despite the tech giant being a key investor of the artificial intelligence firm. On Monday, Mr Nadella announced that both Mr Altman and fellow OpenAI co-founder Greg Brockman would be joining his company. “We’re extremely excited to share the news that Sam Altman and Greg Brockman, together with colleagues, will be joining Microsoft to lead a new advanced AI research team,” Mr Nadella wrote on X, formerly Twitter. “We look forward to moving quickly to provide them with the resources needed for their success.” Mr Altman replied to the post: “The mission continues.” Mr Altman had previously posted a picture of himself wearing an OpenAI guest pass over the weekend, together with the caption: “First and last time I ever wear one of these.” Mr Nadella followed up his original post on X with further details about what Mr Altman’s new role might be within the company. “I’m super excited to have you join as CEO of this new group, Sam, setting a new pace for innovation,” he wrote. “We’ve learned a lot over the years about how to give founders and innovators space to build independent identities and cultures within Microsoft, including GitHub, Mojang Studios, and LinkedIn, and I’m looking forward to having you do the same.” Read More OpenAI in talks to bring Sam Altman back days after CEO ouster, reports say OpenAI co-founder Sam Altman ousted as CEO ChatGPT Plus stops signups after major update ChatGPT creator mocks Elon Musk in brutal tweet ChatGPT goes offline ChatGPT update allows anyone to make their own personalised AI assistant

The internet and mobile phones may not have a “blanket negative effect” on wellbeing and mental health, researchers say. A large international study used data from two million people aged 15 to 89 in 168 countries, and found smaller associations than would be expected if the internet were causing widespread psychological harm. The researchers say that if the link between internet use and poor health were as universal and robust as many think they would have found it. We looked very hard for a ‘smoking gun’ linking technology and wellbeing and we didn’t find it Professor Andrew Przybylski, Oxford Internet Institute However, the study did not look at social media use, and although the data included some young people, the researchers did not analyse how long people spent online. Professor Andrew Przybylski, of the Oxford Internet Institute, and Assistant Professor Matti Vuorre, Tilburg University, and Research Associate, Oxford Internet Institute, carried out the research into home and mobile broadband use. Prof Przybylski said: “We looked very hard for a ‘smoking gun’ linking technology and wellbeing and we didn’t find it.” He added: “The popular idea that the internet and mobile phones have a blanket negative effect on wellbeing and mental health is not likely to be accurate. “It is indeed possible that there are smaller and more important things going on, but any sweeping claims about the negative impact of the internet globally should be treated with a very high level of scepticism.” Looking at the results by age group and gender did not reveal any specific patterns among internet users, including women and young girls. Instead, the study, which looked at data for the past two decades, found that for the average country, life satisfaction increased more for females over the period. Data from the United Kingdom was included in the study, but the researchers say there was nothing distinctive about the UK compared with other countries. Although the study included a lot of information, the researchers say technology companies need to provide more data, if there is to be conclusive evidence of the impacts of internet use. They explain: “Research on the effects of internet technologies is stalled because the data most urgently needed are collected and held behind closed doors by technology companies and online platforms. “It is crucial to study, in more detail and with more transparency from all stakeholders, data on individual adoption of and engagement with internet-based technologies. “These data exist and are continuously analysed by global technology firms for marketing and product improvement but unfortunately are not accessible for independent research.” For the study, published in the Clinical Psychological Science journal, the researchers looked at data on wellbeing and mental health against a country’s internet users and mobile broadband subscriptions and use, to see if internet adoption predicted psychological wellbeing. In the second study they used data on rates of anxiety, depression and self-harm from 2000-2019 in some 200 countries. Wellbeing was assessed using data from face-to-face and phone surveys by local interviewers, and mental health was assessed using statistical estimates of depressive disorders, anxiety disorders and self-harm in some 200 countries from 2000 to 2019.
