Scientists have developed an artificial intelligence (AI) tool that can classify four subtypes of Parkinson’s disease with up to 95% accuracy. Researchers from the Francis Crick Institute and the UCL Queen Square Institute of Neurology in London “trained” a computer program to recognise the subtypes of the condition using images of stem cells from patients. The team said their work, published in the journal Nature Machine Intelligence, could pave the way for personalised medicine and targeted drug discovery. Sonia Gandhi, assistant research director and group leader of the Neurodegeneration Biology Laboratory at the Crick, said: “We understand many of the processes that are causing Parkinson’s in people’s brains. The hope is that one day this could lead to fundamental changes in how we deliver personalised medicine Sonia Gandhi, Francis Crick Institute “But, while they are alive, we have no way of knowing which mechanism is happening, and therefore can’t give precise treatments. “We don’t currently have treatments which make a huge difference in the progression of Parkinson’s disease. “Using a model of the patient’s own neurons, and combining this with large numbers of images, we generated an algorithm to classify certain subtypes – a powerful approach that could open the door to identifying disease subtypes in life. “Taking this one step further, our platform would allow us to first test drugs in stem cell models, and predict whether a patient’s brain cells would be likely to respond to a drug, before enrolling into clinical trials. “The hope is that one day this could lead to fundamental changes in how we deliver personalised medicine.” Parkinson’s is a condition in which parts of the brain become progressively damaged over many years. Symptoms include involuntary shaking of particular parts of the body, slow movement, and stiff and inflexible muscles. But there is also a wide range of other physical and psychological symptoms such as depression and anxiety, problems sleeping, and memory problems. These vary from person to person due to differences in the underlying mechanisms causing the disease. The researchers said that until now, there was no way to accurately differentiate Parkinson’s subtypes. It means people are given nonspecific diagnoses and do not always have access to targeted treatments, support or care, the team added. For the study, the researchers generated stem cells, which have the ability to develop into specialised cell types in the body, from patients’ own cells. The team then used those cells to chemically create four different subtypes of Parkinson’s: two involving pathways leading to toxic build-up of a protein called alpha-synuclein and two involving pathways associated with dysfunctional mitochondria, the cell’s battery packs. Working with the British technology company Faculty AI, the team developed machine-learning algorithms which were able to accurately predict the Parkinson’s subtype when presented with images it had not seen before. James Evans, a PhD student at the Crick and UCL, and first co-author of the study, said: “Now that we use more advanced image techniques, we generate vast quantities of data, much of which is discarded when we manually select a few features of interest. “Using AI in this study enabled us to evaluate a larger number of cell features, and assess the importance of these features in discerning (the) disease subtype. “Using deep learning, we were able to extract much more information from our images than with conventional image analysis. “We now hope to expand this approach to understand how these cellular mechanisms contribute to other subtypes of Parkinson’s.” Read More Charity boss speaks out over ‘traumatic’ encounter with royal aide Ukraine war’s heaviest fight rages in east - follow live Oxford scientists find no evidence to suggest Facebook not good for wellbeing Many adults would struggle to understand video-sharing platforms’ rules – Ofcom Ozzy Osbourne PlayStation tweet which failed to reveal link to Sony banned

The man who is 'ageing backwards' Bryan Johnson has revealed he now uses a machine to generate tears after his body stopped producing them. Johnson, who has the 'biological age of an 18-year-old' has gone viral for going to extremes to achieve peak health, however, it would seem everything isn't going so smoothly with his eyesight. "I have a dry eye condition which we found in our routine [doctor] visit", he tells the camera. He then films himself using the FDA-approved iTear100, which massages the side of his nose to stimulate tear ducts. Sign up to our new free Indy100 weekly newsletter

The co-founder of Russian internet giant Yandex, Arkady Volozh, on Thursday condemned what he described as Moscow's "barbaric" invasion of Ukraine, days after criticism in Russia over his apparent efforts to distance himself from the country.

You may have noticed these weird phone numbers while watching reruns of your favorite ’50s-era TV show—and though they look like gibberish to modern phone-users, they were perfectly normal at the time.

New constraints on US investments in advanced technology in China will exacerbate a slump in deals between the world's top two economies and deliver a "major blow" to Chinese startups, analysts and investors told CNN Thursday.

An AI meal app suggested a "meal" that would create chlorine gas. The New Zealand app, created by supermarket chain Pak ‘n’ Save, was advertised as a way for customers to creatively use leftovers during the cost of living crisis. Users enter the ingredients they have in their homes and the app generates recipes. But New Zealand political commentator Liam Hehir noticed it made “aromatic water mix” when he put in ingredients that would create chlorine gas. The bot recommended the recipe as “the perfect nonalcoholic beverage to quench your thirst and refresh your senses”. “Serve chilled and enjoy the refreshing fragrance,” it said, despite the fact that inhaling chlorine gas can cause lung damage or death. Sign up to our free Indy100 weekly newsletter This was not the only dodgy recipe the app came up with. Posting on social media, others weighed in with grim recipes they had found, including "bleach-infused rice surprise" and "mysterious meat stew" made with human flesh. A spokesperson for the supermarket said they were disappointed to see “a small minority have tried to use the tool inappropriately and not for its intended purpose”. In a statement, they said that the supermarket would “keep fine tuning our controls” of the bot to ensure it was safe and useful, and noted that the bot has terms and conditions stating that users should be over 18. In a warning notice appended to the meal-planner, it warns that the recipes “are not reviewed by a human being” and that the company does not guarantee “that any recipe will be a complete or balanced meal, or suitable for consumption”. “You must use your own judgement before relying on or making any recipe produced by Savey Meal-bot,” it said.

It’s been revealed that Mars is spinning at a faster and faster rate, effectively shortening the length of a day on the planet’s surface. Data collected by NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander has left experts puzzled. The length of every day is shortening by a fraction of a millisecond each year, and experts don’t know exactly why it’s happening. The findings also showed that the planet is 'wobbling' in an unusual way due to the molten metal “sloshing” in its core. Sign up to our free Indy100 weekly newsletter The reason for the planet speeding up is unclear, but one theory states that ice building up at the poles could be behind it. Dr Bruce Banerdt of NASA’s Jet Propulsion Laboratory in Southern California and his colleagues are behind a study into the findings, which were published in the journal Nature. Dr Banerdt said: “It’s really cool to be able to get this latest measurement — and so precisely. “I’ve been involved in efforts to get a geophysical station like INSight onto Mars for a long time.” He went on to say: “Results like this make all those decades of work well worth it.” Meanwhile, another new study has found that Mars may have once had wet and dry seasons – like those on Earth – conducive to the emergence of life. Researchers have discovered fossil evidence suggesting the red planet had a cyclical climate more than three billion years ago. Nasa also recently discovered “diverse organic matter” on the surface of Mars, which could change our understanding of the planet and the search for life in the universe.
