Superconductor breakthrough could represent ‘biggest physics discovery of a lifetime’ – but scientists urge caution
Scientists have claimed to make a breakthrough that would be “one of the holy grails of modern physics” – but experts have urged caution about the results. In recent days, many commentators have become excited by two papers that claim to document the production of a new superconductor that works at room temperature and ambient pressure. Scientists in Korea said they had synthesised a new material called LK-99 that would represent one of the biggest physics breakthroughs of recent decades. Superconductors are a special kind of material where electrical resistance vanishes, and which throw out magnetic fields. They are widely useful, including in the production of powerful magnets and in reducing the amount of energy lost as it moves through circuits. They are also often impractical, since they require low temperatures and high pressure. That means that they cannot be used in most traditional circuits, for instance. Since the beginning of the last century, scientists have been working not only to understand superconductivity but also develop new materials that would allow the phenomenon to be harvested at ambient temperatures and pressures. That has not been successful, and the discovery of such a material would mark a major breakthrough in physics. The new papers, published in recent days as a preprint on the website arXiv, claims to have overcome that problem. The researchers said they had not only found a way to synthesise such a superconducting material, but also that it could be done relatively easily – leading to huge excitement on social media. One Twitter thread from Alex Kaplan, a recent Princeton graduate who is now head of coffee product at startup Cometeer, helped propel the news into the mainstream. His thread had been viewed 8.5 million times, Twitter said, and has been retweeted more than 10,000 times. “Today might have seen the biggest physics discovery of my lifetime. I don’t think people fully grasp the implications of an ambient temperature / pressure superconductor,” he wrote in a long thread that went on to explain the possible applications of the material. Mr Kaplan pointed to the fact that vast amounts of energy are lost in the transmission of electricity across the world, that the the authors claimed material could be made in just 34 hours with simple equipment, and that such a superconductor would have revolutionary uses in everything from nuclear fusion reactors to batteries and quantum computers. Scientists away from the work agreed that such a breakthrough would be hugely significant. But they urged caution, pointing to the fact that the paper has not yet gone through the peer review process, the results have not been replicated, and that there could be other explanations for the apparently astonishing behaviour described in the work. “A real, working room-temperature superconductor which works at ambient pressure would be one of the holy grails of modern physics, unlocking major new developments in energy, transportation, healthcare, and communications,” said Mohammad Yazdani-Asrami of the University of Glasgow’s James Watt School of Engineering. “As it stands, however, the paper is not yet peer-reviewed and has not yet been tested in other labs to see if other researchers can reproduce its results. These are both key to determining for sure whether the world should be getting excited about the authors’ claims, which need much more scrutiny at this early stage. If the claims of findings are approved, perhaps, this is one of the most significant achievements of last few decades in physics and material engineering.” Others voiced specific concerns about the paper. Some of the results meant that other researchers working on superconductors were not convinced by the claims made in the paper. “The recent preprint by Lee, Kim and Kwon suggesting that they have observed room temperature superconductivity in the copper doped lead phosphate system, without the need for very high applied pressures, is interesting, but not yet wholly convincing,” said Susannah Speller, Professor of Materials Science at the University of Oxford, and Chris Grovenor, Professor of Materials at the University of Oxford. Professors Speller and Grovenor pointed to the fact that the data did not show the behaviour that would be expected to happen when the material became superconducting. Features that would be expected to be evident in the results were not, they said, and “and so it is too early to say that we have been presented with compelling evidence for superconductivity in these samples”. John Durrell, professor of superconductor engineering at Cambridge University, said that it could take considerable time to see the practical benefits of the breakthrough, even if the team’s results were confirmed. “There will be understandable scepticism about this result in the community as there have been numerous reports of room temperature superconductors over the years which have not held up,” he told The Independent. “I would, therefore, personally withhold judgement on this work until it becomes clear if the result is reproducible in other laboratories. “From my engineering point of view, a practical room temperature superconductor would be potentially transformative – allowing a host of exciting applications such as cheap MRI machines, more compact and efficient motors and low loss power transmission. “However, there can be significant challenges in turning a newly discovered superconducting material into a practical material. In previous cases, this has taken one or two decades and is not always possible.” Read More Europe to cover continent in fast EV chargers under new law Elon Musk takes control of @X account from user who had held it for 16 years iPhone users urged to check their photo library amid fears they could be deleted Europe to cover continent in fast EV chargers under new law Elon Musk takes control of @X account from user who had held it for 16 years iPhone users urged to check their photo library amid fears they could be deleted

No ‘smoking gun’ linking mental health harm and the internet – study
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.
