Going on a spacewalk might sound like a lot of fun – but in reality it’s no walk in the park. From their muscles getting less dense all the way to erectile dysfunction, astronauts have to put up with all sorts of things going wrong with their body. And none more gross than what happens to their fingernails. Turns out they just fall right off. The technical term for this is onycholysis, and it has to do with how much – or how little – atmospheric pressure there is in space. Because there is so little ambient pressure in space, astronaut’s space suits need to be pressurised to keep the human body intact. But that’s not good for the hands, it turns out. “Injuries to the hands are common among astronauts who train for extravehicular activity (EVA),” says a 2015 conference paper by space specialists Wyle Laboratories. “When the gloves are pressurized, they restrict movement and create pressure points during tasks, sometimes resulting in pain, muscle fatigue, abrasions, and occasionally more severe injuries such as onycholysis. “Glove injuries, both anecdotal and recorded, have been reported during EVA training and flight persistently through NASA's history regardless of mission or glove model." A 2010 study looked at 232 hand injuries sustained by astronauts, and found that the wider your knuckle joints, the more likely you are to suffer in a space suit. The study suggested that because space suit gloves limit the mobility of these knuckles, the fingers then get put under more pressure. This, in turn, means less blood gets to the fingers, and risks onycholysis. Ouch. Work has been done to try to improve the design of space suit gloves, of course. One team found that the more tailored they were to each astronaut’s finger length the less likely they were to lose their fingernails. That’s no mean feat, however. These gloves are made of at least four layers: one which touches the skin, one which helps create the pressurised environment, another one which makes the pressure layer less stiff, and an outer layer which protects the astronaut from everything on the outside. Mercifully for NASA astronauts at least, they usually have their gloves fitted to each wearer, and with new space suit design moving forward each day, the number of injuries is decreasing. Nonetheless, it sounds like a trip to space is no time for a manicure.

Meta, the parent company of Facebook and Instagram, is rolling back its COVID-19 misinformation rules

It’s footage that’s fascinated conspiracy theorists for decades, but artificial intelligence is making people look at the most famous alleged sighting of ‘Bigfoot’ in a new light. Back in 1967, a clip known as the Patterson–Gimlin film claimed to show the mysterious creature, also known as ‘sasquatch’, walking through the Six Rivers National Forest in California. Roger Patterson and Robert Gimlin shot a figure moving in the woods in low resolution footage and claimed that they had discovered proof of the urban legend known as Bigfoot. The pair claimed at the time they tracked the figure before setting up filming equipment and capturing grainy video which looks briefly at the camera. Sign up to our new free Indy100 weekly newsletter While it was dismissed by the scientific community at the time and seen as a hoax by most people, it’s been poured over by conspiracy theorists ever since. It’s been analysed many times since, but new artificial intelligence has been used to present a clearer image than ever before. The clip has been stabilised and de-grained, and the results are clearer than ever. Social media user Rowan Cheung often shares the “latest developments in the world of artificial intelligence” and he posted the footage. Just as many conspiracists will have feared, the newly treated footage proves that it was clearly just a guy in a gorilla costume all along. Yes, we all knew that already, but this newly developed footage offers the clearest look at an infamous piece of footage yet – and people were quick to react on social media. “Nooppe! thats just a dude on his way to a costume party!” one wrote. Another said: “This is the ai work we needed.” One more said: “Just some bro out for a stroll.” “So it’s a dude in a gorilla suit?” a comment read. Artificial intelligence, it seems, has the power to surprise us when we least expect it. It’s not the first time ‘Bigfoot’ has made headlines this year, after people claimed to have discovered a sighting via Google Maps. Have your say in our news democracy.

Artificial intelligence (AI) can generate Caucasian faces that seem more realistic than actual human faces, according to a new study. As per the research, published in Psychological Science and led by experts at the Australian National University (ANU), more people thought the AI-generated white faces were human than the faces of real people. The study found, however, that the same did not apply to faces generated of people of colour. If white AI faces are consistently perceived as more realistic, this technology could have profound implications for people of colour by ultimately reinforcing racial biases online Dr Amy Dawel According to senior author of the paper, Dr Amy Dawel, the reason for the notable difference between generated Caucasian faces and people of colour comes down to the fact that AI algorithms are trained disproportionately on white faces. Dr Dawel said: “If white AI faces are consistently perceived as more realistic, this technology could have profound implications for people of colour by ultimately reinforcing racial biases online. “This problem is already apparent in current AI technologies used to create professional-looking headshots. “When used for people of colour, the AI is altering their skin and eye colour to those of white people.” Researchers found when it comes to AI “hyper-realism”, most people did not realise they were being fooled. Study co-author and ANU PhD candidate Elizabeth Miller said researchers found that most of the study participants who were most confident that their answers were correct paradoxically thought that the AI faces were real. She said: “This means people who are mistaking AI imposters for real people don’t know they are being tricked.” The researchers were also able to discover why AI faces are fooling people. Although there were still physical differences between the AI and human faces, study participants still managed to misinterpret them. Dr Dawel revealed more in-proportion faces were typical signs that AI had generated a face. However, people mistook it as a sign of humanness. She added: “We can’t rely on these physical cues for long. AI technology is advancing so quickly that the differences between AI and human faces will probably disappear soon.” She said this could have profound implications regarding online misinformation and identity theft. Dr Dawel urged public transparency around AI so society can identify issues with the technology before they become more significant problems. “Given that humans can no longer detect AI faces, society needs tools that can accurately identify AI imposters,” she said. “Educating people about the perceived realism of AI faces could help make the public appropriately sceptical about the images they’re seeing online.” Read More AI among the biggest threats to the UK, cyber security agency warns Meta faces renewed criticism over end-to-end encryption amid child safety fears Call of Duty launch sparks record traffic on broadband networks Crypto investment fraud warning issued by major bank Council investigating extent of cyber attack that affected website and systems Setback for Ireland as EU legal adviser recommends revisit of Apple tax case
