A Nasa scientist has said chemicals found on Mars would be considered signs of ancient life if they were found on Earth, leading to suggestions the Red Planet could potentially have harboured life. Dr Michelle Thaller said: “On Mars we see chemistry that on Earth, if it were here, we would say is due to life. “But the question is, how well do we understand Mars and are we being fooled by something?” It’s not a done deal, of course. Signs of ancient life that we find regularly on Earth may not mean the same thing elsewhere, particularly with the vastly different conditions between the two planets. Dr Thaller told The Sun she is certain there is life out there in our solar system, but did not reveal the exact chemical substance that had been found. Nasa has previously found methane on Mars, which it said “could have supported ancient life”, and the organisation has also revealed plans to look for amino acids that haven’t yet been destroyed by space radiation. Organic chemicals like amino acids are used by archaeologists to determine whether life was present. A blog post from the US space agency said: “Amino acids can be created by life and by non-biological chemistry. “However, finding certain amino acids on Mars would be considered a potential sign of ancient Martian life because they are widely used by terrestrial life as a component to build proteins. “Proteins are essential to life as they are used to make enzymes which speed up or regulate chemical reactions and to make structures.” Alexander Pavlov of Nasa’s Goddard Space Flight Center in Greenbelt, Maryland, added: “Our results suggest that amino acids are destroyed by cosmic rays in the Martian surface rocks and regolith at much faster rates than previously thought. “Current Mars rover missions drill down to about two inches (around five centimeters). “At those depths, it would take only 20 million years to destroy amino acids completely.” That may sound like a long time, but Nasa is looking for life that is billions of years old, because scientists think Mars would have been more like Earth back then. Dr Thaller said it was important not to actually say there were signs of life until there is 100 per cent confirmation. “The solar system may be teeming with simple life, microbial life. “We just have to get that 100% certainty to say that we found it and we don’t have that yet.” Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

With the rise of AI, we've all seen how powerful this new technology can be particularly when it comes to music. As a result, people have been using AI to perfectly replicate the singing voices of different artists such as Drake, Ariana Grande, Billie Eilish, Taylor Swift and Harry Styles in order to make AI covers of different songs. For example, there is a viral AI cover of Harry Styles singing in a duet with Taylor Swift on her track Style which fans have been going crazy about. While AI can also be used to create deep fakes of celebrities too - where the celeb's face is digitally imposed on someone else's body which is often used to spread misinformation or for malicious intent. But what do artists think about this issue? Here are the celebrities who have spoken out so far on the topic of AI: Drake An AI song called "Heart on My Sleeve" that used Drake's and the Weeknd's voices went viral before being taken down by music streaming services. While Drake himself hasn't commented on all the AI songs that have been created, he did express his disapproval of the practice after the rapper responded to an AI-generated cover of him rapping Ice Spice’s “Munch”, writing: “This is the final straw AI.” Grimes Grimes has expressed enthusiasm towards the new AI-generated songs - and has told her fans they can use her voice to create their own tracks. Taking to Twitter, she shared a New York Times article about the viral AI-generated song using Drake and The Weeknd's voice. She wrote: "I'll split 50 per cent royalties on any successful AI-generated song that uses my voice. Same deal as I would with any artist I collab with. Feel free to use my voice without penalty. I have no label and no legal bindings." "I think it's cool to be fused w a machine and I like the idea of open-sourcing all art and killing copyright," she added. Though, later she did add a clarification on the platform as to what circumstances would cause her to get certain AI songs taken down for copyright - where "rly rly toxic lyrics," are used with her voice. "Ok hate this part but we may do copyright takedowns ONLY for rly rly toxic lyrics w grimes voice: imo you'd rly have to push it for me to wanna take smthn down but I guess plz don't be *the worst*. as in, try not to exit the current Overton window of lyrical content w regards to sex/violence. Like no baby murder songs plz," she wrote. "I think I'm Streisand effecting this now but I don't wanna have to issue a takedown and be a hypocrite later. ***That's the only rule." Rly don't like to do a rule but don't wanna be responsible for a Nazi anthem unless it's somehow in jest a la producers I guess "- wud prefer avoiding political stuff but if it's a small meme with ur friends we prob won't penalize that. Probably just if smthn is viral and anti abortion or smthn like that. Grimes added: "Rly rly don't like adding rules so I apologize but this is the only thing." Most recently, the singer and producer has shared a guide on how to do this, and shared the link in a tweet: "HOW TO MAKE MUSIC FEAT GrimesAI - we can distribute it for you and you can earn royalties from your work." Billie Eilish During an appearance on The Late, Late Show with James Corden back in May this year, Billie Eilish shared her thoughts on AI. "I feel like my approach is not as optimistic, I'm a little bit scared of it," she admitted. "I'm a little scared of what someone could create of me doing something with it." Eilish added: "Scary, scary to me, it just looks so real," as she went on to note how it's "One of the most impressive things I've encountered in my life." The singer's comments come after deepfake porn' of singer Eilish was promoted on people's TikTok in December last year.

If the thought of jetting off to Mars to live doesn’t scare you enough, imagine what it would be like going with people whose personalities you cannot stand. To avoid that happening, scientists have come up with a simulation that can determine the right and, importantly, wrong, personality types to send up to colonize Mars. 28 different simulations of colonies on Mars were run as part of the study to establish which type of people stood the best chance of settlement and survival. While the study was published on pre-print server arXiv, it had not yet been peer-reviewed. The study worked on the assumption that there would already be some kind of infrastructure in place, including power, food, air and water being locally produced and available. As part of the model, there would also be regular supply deliveries from Earth. Those behind the simulation gave each agent their own attributes, skills and personalities and let the simulation run as they interacted, socialised and problem-solved together. In the paper, the researchers explained: “Each agent is granted skills associated with their civilian and military occupational specialities consistent with NASA’s Human Factors and Behavioral Performance Element research.” Different personality types included: “Agreeables” – they score low on levels of competitiveness and aggression. “Neurotics” – these people are highly aggressive, competitive, and are much less able to handle routine change or boredom. “Reactives” – they tend to have a “competitive interpersonal orientation”. “Socials” – people who are extroverted and require a lot of social interaction. As for the groups themselves, the numbers within each simulation differed with the lowest amount being 22 individuals. The study found that the presence of neurotics made the team have a worse chance of survival and that these people in particular “suffered during life on the colony”. The researchers: “Martians with the neurotic psychology and a high coping capacity benefit the least from interaction with other Martians, and are penalized the most if they have a low coping capacity. “Our results suggest that this effect is a driver of the Martian population decline, and once minimized or removed, can produce a stable settlement.” A lot to process there if you identify as neurotic.

Antarctica might be the only continent on Earth with no natural human habitation, but it’s emerged that an “Antarctica accent” is very much a thing. Despite having no locals, thousands of scientists have made up an ever-changing population in research stations over the years. The continent is so isolated and the level of interaction between researchers is so intense, that a common accent is beginning to emerge there despite people coming from different parts of the world. At its busiest points in the year during the summer, Antarctica is home to around 5,000 people. Only around 1,000 people live there during the winter months. The idea of accents changing due to human interaction on Antarctica is no different to the phenomenon seen throughout history at a glacial pace. However, given the very specific sample size, it’s an opportunity for scientists to study it at a much quicker rate and on a much smaller scale. Experts at the Ludwig Maximilian University of Munich published a study in 2019 which focused on the change in accents observed in 11 people who took part in the British Antarctic Survey. @human.1011 There’s an Antarctic Accent! #language #linguistics #english #antarctica Of the 11 who were studied, eight came from England, one from the US, one from Germany and one from Iceland. Their voices were recorded every six weeks, and the team found that over time they developed longer vowel sounds. There was a physical change too, with participants pronouncing the “ou” sound in the front of their mouths rather than the back of their throats. Speaking to IFL Science, Jonathan Harrington, study author and Professor of Phonetics and Speech Processing at the Ludwig-Maximilians University of Munich said: "The Antarctic accent is not really perceptible as such – it would take much longer for it to become so – but it is acoustically measurable. "It's mostly an amalgamation of some aspects of the spoken accents of the winterers before they went to Antarctica, together with an innovation. It's far more embryonic [than conventional English accents] given that it had only a short time to develop and also, of course, because it's only distributed across a small group of speakers.” Sign up for our free Indy100 weekly newsletter Have your say in our news democracy.

Baffled scientists are trying to unravel the mystery of how a meteorite left Earth’s atmosphere and somehow came back again. Unlike boomerangs, meteorites don’t have a reputation for coming back around again, so when a black rock found in Morocco in 2018 seemed to have done just that, it left the scientific community confused. The rock, whose official name is Northwest Africa (NWA) 13188, is a scientific first (that we know of) to have left the Earth’s atmosphere, gone into outer space and returned again. The 646-gram piece of rock is remarkable not only for its journey but also its makeup. NWA 13188 has a bubbly texture and contains crystals. Its chemical components suggest that the rock is made out of the minerals produced by molten minerals that come from volcanic activity. It also possesses trace elements and oxygen isotopes, which suggests to scientists that it is not the typical meteorite that originates in space, but instead, it originated on Earth itself. However, according to a geophysicist from the French National Centre for Scientific Research, Jérôme Gattacceca, who studied the rock and presented the findings, it has undergone an interesting journey in orbit. Scientists can identify this because of the presence and concentration levels of Helium-3, Beryllium-10, and Neon-21, which suggest exposure to cosmic rays that are not present in Earth’s atmosphere. Compared to other more traditional meteorites scientists have studied, the concentrations are lower on NWA 13188 but are still higher than rocks on Earth. It is thought that NWA 13188 could have been expelled from Earth and in orbit for thousands of years. Scientists said, “We consider NWA 13188 to be a meteorite, launched from the Earth and later re-accreted to its surface”. Despite the rock originating on Earth, the team said it fits the definition of a meteorite since it has achieved orbit. The definition states: “Material launched from a celestial body that achieves an independent orbit around the Sun or some other celestial body, and which eventually is re-accreted by the original body, should be considered a meteorite. “The difficulty, of course, would be in proving that this had happened, but a terrestrial rock that had been exposed to cosmic rays and had a well-developed fusion crust should be considered a possible terrestrial meteorite.” It is not yet understood how the rock came to be launched from Earth into space, as researchers said it still “remains to be determined”.

The emphasis on a good night's sleep is nothing new. But now, neuroscientist, Dr Andrew Huberman, has shared one routine that he suggested can make you "better at everything." In a YouTube talk on After Skool, Dr Huberman said he immediately starts his day with a sunrise walk at 6.30am. "Getting outside for a 10-minute walk or a 15-minute walk is absolutely vital to mental and physical health," he shared. Despite coffee being the get-up-and-go drink for most, Huberman says the first beverage he consumes is salty water, as he claims it helps improve bodily functions. "There are certain foundational behaviours - certain dos and don'ts that set the stage for you to be better at everything," he continued. "It always comes back to two elements - that's sleep and what I call non-sleep deep rest. Sleep is the fundamental practice or part of our 24-hour cycle where if you don't get it on a consistent basis, you are down-regulating your ability to do everything." He went on to discuss a "90-minute bout of work," in which he says he turns his phone off to fully optimise this time. "You'd be amazed how much you can get done in 90 minutes if you are focused," he said. Huberman then ensures he gets in an hour's worth of exercise before exposing himself to cold temperatures such as an ice bath. The NHS states that there are no official guidelines regarding how much sleep a person should get each night as everyone is different. "On average, a 'normal' amount of sleep for an adult is considered to be around seven to nine hours a night. Children and babies may sleep for much longer than this, whereas older adults may sleep less," they wrote. Sign up for our free Indy100 weekly newsletter Have your say in our news democracy.

Robots could soon take over doctors’ jobs, according to experts. A recent study found that AI technology was able to accurately diagnose patients in a healthcare setting. Investigators found the controversial model ChatGPT to be nearly 72 per cent accurate in making clinical decisions. It was also 77 per cent accurate in making final diagnoses. It was able to come up with possible diagnoses, final diagnoses and care management decisions. The artificial intelligence chatbot was found to perform equally well in both primary care and emergency settings. Researchers at Mass General Brigham in Boston, Massachusetts conducted the study. They tested how ChatGPT would be able to work through an entire clinical encounter with a patient. This included recommending a diagnostic workup, deciding the clinical management course, and ultimately making the final diagnosis. It was tested by putting 36 published clinical descriptions into ChatGPT. Patient gender, age and symptoms were put into the language model. ChatGPT was then given further information and asked to make management decisions and a final diagnosis. This simulates the process of seeing a real patient. However, scientists also found it was less accurate - 60 per cent - at making several possible diagnoses. Co-author Marc Succi said: “Our paper comprehensively assesses decision support via ChatGPT from the very beginning of working with a patient through the entire care scenario, from differential diagnosis all the way through testing, diagnosis, and management. ”No real benchmarks exist, but we estimate this performance to be at the level of someone who has just graduated from medical school, such as an intern or resident. ”This tells us that LLMs in general have the potential to be an augmenting tool for the practice of medicine and support clinical decision making with impressive accuracy.” The research team say they will soon be looking at whether AI tools can improve patient care and outcomes in resource-constrained areas of hospitals.
