A recent study has found that eating strawberries daily could reduce the risk of developing dementia. Researchers at the University of Cincinnati claim that by eating the fruit every day, certain people of middle age could reduce their risk of dementia. The 12-week study published in Nutrients had 30 overweight patients - who had complained of mild cognitive impairment - abstain from eating berries, aside from a daily packet of supplement powder mixed with water and consumed with breakfast. Half of the participants, who were 50 to 65 years old, received a powder that contained the equivalent of one cup of whole strawberries (the standard serving size), whilst the other half received a placebo. Participants' long-term memory, mood, and metabolic health were measured by researchers. The team found that those who had taken the strawberry powder had performed better on a wordlist learning test, as well as having a significant reduction in depressive symptoms. "Both strawberries and blueberries contain antioxidants called anthocyanins, which have been implicated in a variety of berry health benefits such as metabolic and cognitive enhancements," said Robert Krikorian, professor emeritus in the UC College of Medicine's Department of Psychiatry and Behavioural Neuroscience. "There is epidemiological data suggesting that people who consume strawberries or blueberries regularly have a slower rate of cognitive decline with ageing." Ellagitannins and ellagic acid are also found in strawberries, which are known to possess anti-inflammatory, antioxidant, antimicrobial, and anticancer properties. Krikorian went on to explain that strawberries may have improved cognitive function by reducing inflammation in the brain. "Executive abilities begin to decline in midlife and excess abdominal fat, as in insulin resistance and obesity, will tend to increase inflammation, including in the brain," he explained. The university did, however, acknowledge that Krikorian's research was partly funded by the California Strawberry Commission. Although said that the group had no role in the design of the study, data collection and analysis, or publication of the results.

A new initiative will aim to find missing people faster by issuing urgent appeals directly onto people’s phones via the Trainline app. The app will display images of people who have gone missing nearby and has the potential to reach millions of train travellers across the country, the charity Missing People has said. The project has been supported by relatives who are still searching for missing family members. The father of Andrew Gosden, who vanished more than 16 years ago, said anything that can help raise awareness of his son or any missing person is vital. Andrew, from Doncaster, South Yorkshire, was 14 when he disappeared on September 14 2007 and his case became one of the most high-profile missing person probes in the North. He emptied his bank account of about £200 and went to Doncaster station, where he bought a one-way ticket to London King’s Cross. His family and police believe he boarded a train at 9.35am, arriving at King’s Cross at 11.20am. CCTV images captured at the London station are the last known sighting of Andrew, with no further information about his movements corroborated by officers. In 2008 Andrew became the first person to feature in a new nationwide milk carton campaign aimed at tracing missing people. Two men were arrested in December 2021 by detectives investigating Andrew’s disappearance but they were eliminated from the police inquiry in September. Speaking about the Trainline project, Andrew’s father Kevin Gosden said: “If this had existed back in 2007, Andrew’s image could have been displayed to thousands of members of the public in the area where he went missing. “Anything that can help to raise awareness of Andrew, and the appeals for any missing person, is vital in keeping the search active and ensuring people are continuing to keep a look out for those who are missing”. Mr Godsen added: “It’s so important to have these appeals out there. You never know when someone might remember something, or may have seen a missing person. “It’s also important to know that there is help for anyone considering disappearing, including support that may help people take the step to return home, or think twice before leaving in the first place.” Paul Joseph, head of helplines at Missing People, said: “When someone vulnerable has disappeared, they can often use the transport network as a safe place. “Missing People is so proud to be working with Trainline to raise awareness of individual disappearances. “Together, we hope to raise awareness and potentially help find missing people. For the loved ones of those featured, knowing that action is being taken to find them, helps to keep hope alive.” A British Transport Police spokesperson added: “Rail passengers can play a vital role in alerting the authorities to people who are at risk. Your reports may help rescue someone from a dangerous situation or even save a life. “There are over 2,500 stations and 10,000 miles of track in Great Britain. These new alerts are so powerful because they can harness the eyes and ears of people who may be in the same train carriage as a missing person.” Read More Data protection watchdog offers tips on buying smart devices on Black Friday Meta to allow users to delete Threads accounts without losing Instagram AI among biggest threats to next UK election, cyber security agency warns AI can create Caucasian faces that look more real than actual humans – study 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

Elon Musk’s X is now valued at about $19bn or less than half of what he paid to buy the social media company, according to a new report. The multibillionaire Tesla and SpaceX chief last year finally bought the microblogging platform that was formerly called Twitter for the price of $44bn or $54.20 per share. Mr Musk’s purchase was completed after a months-long legal battle with the company. A new internal valuation has now found there to have been a 56 per cent decrease in the company’s value over the last 12 months, suggested internal documents. Stock grants handed out to employees showed X/Twitter is now worth about $19bn, Fortune reported on Monday. Mr Musk earlier said he had overpaid for the social media platform that he called “an inverse start-up.” In March, he told employees in an email that they would receive stock awards based on a $20bn valuation of the firm. The valuation drop comes as several high-profile advertisers have withdrawn after the Tesla titan’s controversial takeover of the company. Mr Musk’s reign of the platform has been marred by mass layoffs, the chaotic roll out of a number of new features, including the site’s verification process, and the reinstatement of previously suspended high-profile accounts. The company was also rebranded X along with a new logo to replace the bird icon that had been there since the platform’s creation. There have also been rising concerns around X’s content moderation approach. The EU recently opened an investigation into the company as misinformation linked to the Israel-Hamas conflict began to spread on the platform. In July, Mr Musk shared that X is “still negative cash flow” with a “50 per cent drop in advertising revenue plus heavy debt load”. Banks involved in financing the multibillionaire’s deal to buy Twitter are also reportedly struggling to mitigate the impact of platform’s decline in value on their balance sheets. The Tesla and SpaceX boss, however, has remained optimistic about the future of the platform. Mr Musk claimed in an email last year that he saw a “clear, but difficult, path to a >$250B valuation” for the company. In a recent company meeting, he also reportedly expressed his belief that the rebranded X could serve as an all-purpose app with a range of features like job recruitment and dating services. “We’re rapidly transforming the company from sort of what it was, Twitter 1.0, to the everything app with an all-inclusive feature app where you can basically do anything you want on our system,” he said, according to The New York Times.

Scientists have invented a brain implant that allows wearers to communicate using thoughts alone. The speech prosthetic – developed by neuroscientists, neurosurgeons and engineers at Duke University in the US – is able to translate brain signals into words. The researchers claim it is faster and less cumbersome than other brain computer interface and mind reading technologies, and could transform the lives of people suffering from neurological disorders. “There are many patients who suffer from debilitating motor disorders, like ALS or locked-in syndrome, that can impair their ability to speak,” said Gregory Cogan, a professor of neurology at Duke University’s School of Medicine. “But the current tools available to allow them to communicate are generally very slow and cumbersome.” The team was able to pack 256 specially designed microscopic brain sensors onto a postage stamp-sized piece of medical-grade plastic, which was tested on patients undergoing brain surgery for unrelated conditions like having a tumour removed. Participants were asked to listen to a series of nonsensical words like ‘kug’ and ‘vip’ and then speak them aloud. With just 90 seconds of spoken data, an AI algorithm was then used to decode the neural activity into words. The researchers now plan to develop the technology to improve its speed and make it wireless, and have received a $2.4 million grant from the National Institutes of Health to continue. “You’d be able to move around, and you wouldn’t have to be tied to an electrical outlet, which is really exciting,” Professor Cogan said. Duke Institute for Brain Sciences faculty member Jonathan Viventi added: “We’re at the point where it’s still much slower than natural speech, but you can see the trajectory where you might be able to get there.” The research was detailed in a study, titled ‘High-resolution neural recordings improve the accuracy of speech decoding’, published in the journal Nature Communications.
