Scientists have developed a simple test in the search for alien life, they claim. The breakthrough helps the search for the “holy grail” of astrobiology: a reliable test that will determine whether there is or was life on other planets. The discovery uses artificial intelligence to determine with 90 per cent accuracy whether a sample is biological or not. And it could be used on existing samples, researchers say. That might mean, for instance, that we already have gathered the samples that could tell us whether there is life on Mars. Scientists hope that their test could be used on samples already collected by the Mars Curiosity rover’s Sample Analysis at Mars (SAM) instrument. The rover has an instrument on board to analyse those samples, and that data could be used in the test. The findings could also help tell us more about our own planet, revealing the history of mysterious and ancient rocks found on Earth. “The search for extraterrestrial life remains one of the most tantalizing endeavors in modern science,” said lead author Jim Cleaves of the Earth and Planets Laboratory, Carnegie Institution for Science, Washington, DC. “The implications of this new research are many, but there are three big takeaways: First, at some deep level, biochemistry differs from abiotic organic chemistry; second, we can look at Mars and ancient Earth samples to tell if they were once alive; and third, it is likely this new method could distinguish alternative biospheres from those of Earth, with significant implications for future astrobiology missions.” The technique does not look for specific molecules or compounds that could be indicative of life, as much previous work has done. Instead, it looks for small differences in the molecular patterns of samples using different kinds of analysis. It was built by giving an artificial intelligent system data about 134 known samples, with information about whether they are biotic or abiotic. To test it, it was then given new samples – including those from living things, remnants of ancient life and other abiotic samples that did not point to life, such as pure chemicals – and identified them with 90 per cent accuracy. The system also started predicting another kind of sample type, dividing the biotic ones into “living” and “fossils”. That means it could tell the difference between a freshly harvested leaf and something else that died long ago, for instance. Scientists hope that with time it could eventually be able to distinguish other hints in the data, such as signs of photosynthesis or cells that have a nucleus. Previous research has struggled because organic molecules tend t degrade over time. But the new method works even when the samples have decayed and changed significantly, the researchers behind it said. “This routine analytical method has the potential to revolutionize the search for extraterrestrial life and deepen our understanding of both the origin and chemistry of the earliest life on Earth,” said Robert Hazen, of the Carnegie Institution for Science, one of the leaders of the research. “It opens the way to using smart sensors on robotic spacecraft, landers and rovers to search for signs of life before the samples return to Earth.” The findings could also help solve mysteries on life. Many ancient rocks on Earth are at the middle of argument over whether they hold the oldest fossil microbes in life, while others say they do not have any life – and researchers are already feeding data about those rocks from Australia, Canada and elsewhere into the tool. “We’re applying our methods right now to address these long-standing questions about the biogenicity of the organic material in these rocks,” Hazen says. A paper describing the work, ‘A robust, agnostic biosignature based on machine learning’, is published in the Proceedings of the National Academy of Sciences.

There is no evidence to suggest using Facebook is detrimental to wellbeing, Oxford scientists have said, challenging the view that the social media platform is linked to psychological harm. Researchers from the University’s Oxford Internet Institute analysed data from nearly a million people across 72 countries over 12 years – in the largest study of its kind – to understand more about the impact of Facebook on wellbeing. Professor Andrew Przybylski, who co-led the research published in the journal Royal Society Open Science, said: “We examined the best available data carefully – and found they did not support the idea that Facebook membership is related to harm – quite the opposite. “In fact, our analysis indicates Facebook is possibly related to positive well-being.” The research looked at Facebook data from 2008 to 2019, going back to when the platform was in its early stages. “We examined 72 countries’ per capita active Facebook users in males and females in two age brackets, 13-34 years and 35+ years,” the researchers said. The results also showed the association between using Facebook and wellbeing was slightly more positive for males as well as for younger people. Writing in the research paper, the authors said: “Although reports of negative psychological outcomes associated with social media are common in academic and popular writing, evidence for harms is, on balance, more speculative than conclusive.” Professor Matti Vuorre, also of the Oxford Internet Institute, who co-led the study, said: “Our findings should help guide the debate surrounding social media towards more empirical research foundations. “We need more transparent collaborative research between independent scientists and the technology industry to better determine how, when and why modern online platforms might be affecting their users.” Commenting on the study, Peter Etchells, professor of psychology and science communication at Bath Spa University, said: “This is a fascinating study that attempts to link Facebook uptake with measures of mental wellbeing in a broad-strokes manner, using data from over 70 countries. “Contrary to popular sentiment, the researchers didn’t find a negative association between the two; instead, it was generally the case that there were positive associations between country-level Facebook uptake and mental wellbeing. “To my mind, the value in this study lies in proof of principle – it demonstrates that it’s possible to leverage industry data to address meaningful questions about how digital technology interacts with our mental health.” But Prof Etchells said there were some caveats associated with the findings – which the study authors have addressed. He said: “This is a descriptive study, and as such cannot tell us anything about causation – that is, we don’t know how, if, or to what extent, changes in Facebook adoption drive changes in mental wellbeing. “Wellbeing is a complex phenomenon, and even in the context of social media use, we need to be careful drawing any firm conclusions by looking at how people use a single platform such as Facebook.” Read More Move fast and beat Musk: The inside story of how Meta built Threads Japan's tech investor SoftBank trims losses and promises offensive turnaround Chatbots sometimes make things up.
