Universities face a reckoning on ChatGPT cheats
In 2023, a widely used assessment platform, Turnitin, released an AI indicator, reporting high reliability from huge-sample tests. However, many universities opted out of this indicator, without testing it. Noise about high 'false positives' circulated, but independent research has debunked these concerns (Weber-Wulff et al 2023; Walters 2023; Perkins et al, 2024).
The real motivation may be that institutions relying on high-fee-paying international cohorts would rather not know; the motto is 'see no cheating, hear no cheating, lose no revenue'. The political economy of higher education is driving a scandal of unreliable degree-awarding and the deskilling of graduates on a mass scale. Institutions that are biting the bullet, like mine, will struggle with the costs of running rigorous assessments, but know the costs of not doing so will be far greater.
If our pilots couldn't fly planes themselves or our surgeons didn't know our arses from our elbows, we'd be worried – but we surely want our lawyers, teachers, engineers, nurses, accountants, social workers etc to have real knowledge and skills too.
A sector sea change is under way, with some institutions publicly adopting proper exams (maligned as old-fashioned, rote-learning, unrealistic etc) that test what students can actually do themselves. Institutions that are resistant to ripping off the plaster of convenient yet compromised assessments will, I'll wager, have to some day explain themselves to a public inquiry.Dr Craig ReevesBirkbeck, University of London

ChatGPT answers humans through Telex message machine in Amberley
Historians at a museum have connected a 50-year-old Telex machine to modern day artificial intelligence (AI), creating "a conversation spanning decades".Telex was a message transfer service where text would be typed into one machine and printed out on the recipient' users of the machine at Amberley Museum, in West Sussex, will not get a response from another human, instead it will be ChatGPT answering their museum said visitors had been testing out the new machine, which was built "thanks to the ingenuity" of volunteer David Waters. Users can type in questions and receive a printed response from ChatGPT - an AI chatbot.A spokesperson for the museum said: "The experience begins by using a rotary dial to make the initial connection, creating an unforgettable meeting of communication technologies separated by half a century."They said the project "perfectly captures the spirit of Amberley Museum - celebrating our technological past while engaging with the innovations of today."It's a conversation across decades."

Meet Britain's real-life SUPERVILLAIN: Eccentric millionaire lives in a bunker beneath a Cold War radar - and is convinced he's going to find UFOs
Some millionaires might be happy frittering away their hard–earned cash on speed boats, golfing holidays, and perhaps the odd football team or two. But William Sachiti is far from your run–of–the–mill businessman. Much more Blofeld than Bill Gates, Mr Sachiti has decided to use his millions in a far less conventional way. Naturally, that meant buying a Cold War RAF base and firing up the radar station to hunt for UFOs. From his 'supervillain lair' in the nuclear bunker beneath former RAF Neatishead, Norfolk, Mr Sachiti is building what may be the world's most sophisticated UFO–hunting machine. But don't let the secluded compound, legions of robots, and enormous leather swivel chair fool you – Mr Sachiti isn't taking his role as Norfolk's latest supervillain too seriously. 'I'm a bit of a hedonist,' Mr Sachiti told Daily Mail from the freezing cold control room beneath the radar station. 'There's no point being the richest man in the graveyard, I just want to have fun and let people track UFOs.' Mr Sachiti, 41, is a British Zimbabwe–born inventor and entrepreneur best known for making autonomous delivery vehicles for the RAF, robots for the NHS, and for a particularly unsuccessful appearance on Dragon's Den. In 2017, Mr Sachiti founded The Academy of Robotics with the goal of developing autonomous vehicles, robots, and AI systems. His crowning achievement was the creation of Kar–go, a company which, in 2019, made the UK's first roadworthy autonomous car. It was this goal, rather than the hunt for extraterrestrials, which actually led Mr Sachiti to make the unusual business decision to purchase a disused RAF radar station. During the height of Cold War paranoia, RAF Neatishead was a key part of the UK's air defence network, keeping a watchful eye out for a potential nuclear attack. However, by the 1990s, the main radar had been decommissioned, and in 2004, the decision was made to significantly scale back activity at the base. For almost two decades, the site lay unused as the hulking green mass of the radar slowly turned brown with rust. But with private roads safely away from the public and buildings ready to become workshops, the base was the perfect place for Mr Sachiti to test his robots. Who is William Sachiti? William Sachiti is the millionaire owner of the Academy of Robotics, a company dedicated to creating autonomous robots. Mr Sachiti was born in 1984 in Harare, Zimbabwe and came to the UK when he was 17. He appeared on Dragon's Den in 2009 with his company 'Clever Bins', but was rejected by all four dragons. In 2011, he founded the digital concierge service mycityventure, which was sold to SecretEscapes in 2014. His most successful venture is the autonomous car company Kar–go, which created the UK's first roadworthy self–driving car. Mr Sachiti purchased the site in early 2022 and converted it into the headquarters of The Academy of Robotics, where he now lives and works. When The Daily Mail came to visit Mr Sachiti at his home on the former base, the site seemed caught somewhere between a graveyard for ageing military equipment and the playground of an eccentric millionaire. A herd of Scottish deer happily graze amid the remains of concrete pillboxes, and the ground is littered with craters made, not by explosions, but by Mr Sachiti himself to form ponds for the flamingos he plans to introduce. 'When I moved in, I thought it was going to look like Tron, but it's starting to look a lot more like Westworld,' Mr Sachiti said as he gave a tour of the grounds. However, the property's most obvious feature is the enormous Type–84 radar that looms over Mr Sachiti's bungalow. This radar was once responsible for tracking and identifying every aircraft moving over the south of the UK, but it hasn't been used in over two decades. Mr Sachiti's conspicuously villainous office is located deep beneath this structure, down a pitch–black corridor lined with enough concrete and steel to withstand a nuclear blast. Although Mr Sachiti freely admits he doesn't 'know anything' about how radars work, what he does know about is making artificial intelligence. He says: 'I have all the documents of how the Type–84 was made and how all the tech works, so what if I fed all this into a super–intelligent AI and turn it into the world's best radar expert? And that's how I made RadarBot.' RadarBot is just one of the many AI assistants who keep Mr Sachiti company in his somewhat solitary existence at the base. As he talks, Mr Sachiti frequently pulls up various AI assistants to explain various topics and, in one instance, couldn't find the light switch since 'the AI normally does that'. At first, I couldn't see why Mr Sachiti, who has a wife and children and seemed extremely sociable, chose to live on the base by himself. However, it soon became clear that everything was not quite right at RAF Neatishead. As we walked around the grounds, we came across one of Mr Sachiti's beloved deer decomposing under a cloth. Just a month ago, Mr Sachiti explained, someone had broken into the compound and killed a number of deer, leaving their bodies on the ground. In another incident, just weeks before our visit, a workshop holding Mr Sachiti's self–driving car was broken into and vandalised. 'I get horrible messages, constant abuse, they shot my animals, and no one takes it seriously,' said Mr Sachiti. 'It does affect me, I don't have my staff here, I can't have my kids here. There's guns being shot on my property, how could I have my kids in the garden? 'I don't have investor days anymore because you never know who's coming or whether they're going to vandalise the place. I wish people would just call it out more when they see people being horrible online for no reason.' In that isolation, however, what Mr Sachiti does have is a nearly endless amount of time and energy to work on new creations and build his AIs. In fact, part of the reason he invited Daily Mail to the base along with a group of his investors and former RAF radar operators was to prove that this system really worked and that he hadn't just 'been spending too much time in the bunker'. 'There's no such thing as done when you're surrounded by a cluster of super–intelligent AIs and you're tinkering until three or four in the morning,' he said. It was in the depths of such an AI–powered late–night tinkering session that Mr Sachiti's UFO–hunting side–hustle began. Buying the base purchase had come with a catch: to get planning permission, he was required to conduct restoration and renovation on the listed buildings – including the Type–84 radar station. With RadarBot's assistance, Mr Sachiti soon had the Type–84's radar receiver up and running, but was stumped as to what he should actually do with it. That's when Mr Sachiti decided to post on Reddit to see what the internet thought. Whether it was a joke or not, the reply soon came back decisively: Mr Sachiti should hunt for UFOs. 'I think what happens when you work in tech for so long is that certain things become intuitive and just look like they should be possible,' said he said. 'Then when people say it's not possible, it just became a bit of a challenge.' Although it might sound bizarre, Mr Sachiti seems to have seen the prospect of turning the UK's Cold War defences into a UFO–hunting network as a nice way to wind down after work. 'Some people have that car they refurbish over the summer, this is my version of that summer car,' said Mr Sachiti. 'I thought, why not? Either it slowly dies or you do something crazy and a lot of people benefit from it'.' But, as seems to be the case with many of Mr Sachiti's pet projects, his experiments with AI and radar systems were soon going well beyond a simple hobby. Since he couldn't use the Type–84's radar illuminator, it being far too power hungry for civilian use, he was limited to the smaller, passive secondary surveillance radar (SSR). So, instead of using the radar itself as the illuminator, Mr Sachiti's solution was to build a computer program that could listen for the signals which are already out there. 'What I thought is that, instead of using something like a BBC broadcast for reflection, I could use a plane in the sky,' Mr Sachiti said. 'I know where its signal is at all times, so what if I use that plane as an illuminator? And the plane next to it, and the one next to that, or all the planes in the sky.' That gives you a near–perfect picture of everything that is moving in the sky in a 150 to 250–mile radius, to a tested accuracy of 250 metres. Using the rather ominously labelled 'Global Domination Mode' to use the signals from every plane in the sky, Mr Sachiti's radar should pick up every large drone flying above London over 100 miles away. What makes this so bold is that anyone with Mr Sachiti's software can either log in and use RAF Neatishead's SSR or grab a £20 Amazon antenna and scan their own 150–mile radius. In theory, the resulting network would be unjammable, undetectable, unspoofable, and almost impossible to trick with existing stealth technologies. With just 20–30 of these antennas placed strategically around the country, nothing would move in the skies above Britain without Mr Sachiti and his network of UFO hunters seeing it. If you want to hunt for UFOs yourself, you can now download this software for free from Mr Sachiti's website to build your own station or search using RAF Neastishead's Type–84. Mr Sachiti says: 'We essentially ended up in the world's biggest UFO database just for fun.' Asked whether he has considered that the software might have military applications, particularly the possible drone hunting capabilities, Mr Sachiti seemed unconcerned. 'I'm a bit of a happy hippy person, for me it's fun and I don't really ever want to make weapons of war,' says Mr Sachiti. 'This is legitimately a UFO hunting machine, but it could be used for other things which I don't have an interest in.' However, Mr Sachiti's decision to create a 'UFO hunting machine' might have been inspired by something more than a desire to have a bit of fun. He said: 'I remember being in Zimbabwe in Africa, watching Star Trek thinking, 'wow!', so my passion for tech came from literal Star Trek.' But it was also during his childhood in Zimbabwe that Mr Sachiti found himself close to one of the most well–documented UFO sightings in history. In 1994, over 60 children at the Ariel school in Ruwa, Zimbabwe, reported seeing a UFO landing in the school grounds. Many reported having encountered a 'being' and were plagued by a terror that would follow many for their entire lives. Mr Sachiti recalls: 'I was in primary school, at a school named Greatstone Park, and we had just had a hockey game with students from the Aerial school. 'Apparently, the school had just seen a UFO land, and it was the talk of all the schools everywhere. 'So in my youth, we were all drawing pictures of UFOs and aliens and things, and I think maybe that dropped a seed, and that's where it started. Personally, Mr Sachiti says that UFOs' '100 per cent exist' but that he isn't convinced that they are extraterrestrial in origin. He says: 'The next model going down from humans is a chimp, right? But although there's only a 0.3 per cent genetic difference, the smartest chimp on Earth doesn't even know we're here. 'It doesn't know about electricity, the Hubble Space Telescope, all this tech. So if there's a being that's as much smarter than us as we are smarter than chimps, we wouldn't even know it was there. 'Nature didn't evolve from snails, go up to chimps, then to humans and stop there. Nature went past that ages ago, we just can't see it.' However, despite his absolute conviction in their existence and having spent months building a system to find them, Mr Sachiti says he's not bothered about looking for UFOs himself. He said: 'A person who makes a shovel isn't going to go digging for gold. 'I've made the tool and it's my job to make it the best tool I can, and when they find aliens, I hope they'll tell me.' WHAT IS RADAR? HIGH-FREQUENCY RADIO WAVES DEVELOPED DURING WW2 TO AID FIGHTER PILOTS Radar is an acronym, which stands for Radio detection and ranging. It uses high-frequency radio waves and was first developed in World War Two to aid fighter pilots. It works in a simple manner, a machine sends out a wave and then a separate sensor detects it when it bounces back. This is much the same way that sight works, light is bounced off an object and into the eye, where it is detected and processed. Instead of using visible light, which has a small wavelength, radar uses radio waves which have a far larger wavelength. By detecting the range of waves that have bounced back, a computer can create an image of what is ahead that is invisible to the human eye. This can be used to see through different materials, in darkness, fog and a variety of different weather conditions. Scientists often use this method to detect terrain and also see to study archaeological and valuable finds. As a non-invasive technique it can be used to gain insight without degrading or damaging precious finds and monuments.

The power of pulses: 15 easy, delicious ways to eat more life-changing legumes
Worried about rising food prices, your diet's carbon footprint or whether you're eating healthily enough? Believe it or not, there could be a magic bullet: pulses. According to a study by the University of Reading, published in the European Journal of Nutrition in March, adults who eat more pulses – dried beans, peas and lentils – have a higher intake of nutrients including fibre, folate and vitamins C and E; minerals such as iron, zinc and magnesium; and a lower intake of saturated fat and sugar. Similar results have been found in American, Australian and Canadian research. The UK study also found that eating pulses was associated with a more sustainable diet. In her book, Pulse: Modern Recipes with Beans, Peas & Lentils, Eleanor Maidment explains that growing pulses has a positive effect on the environment. 'Many are 'nitrogen fixers', meaning they have the ability to convert nitrogen in the atmosphere into a form that can be used in the soil, making it more fertile for other crops,' she writes. Justine Butler, the head of research at Viva!, says: 'The lowest-impact beef still creates six times the greenhouse gases and uses 36 times more land per gram of protein than peas.' Pulses are filling and good value but, say the Reading researchers, the typical British adult eats only about 15g a day, with the average household spending just £1.68 on pulses a week. UK guidelines state that 80g of pulses (about a third of a tin) counts as one of your five a day. The University of Reading study is part of the Raising the Pulse project, which aims to increase pulse consumption to improve public and planetary health. One of its strategies is adding fava bean (dried broad bean) flour to white bread – similar to a successful programme in Denmark using rye flour to increase wholegrain consumption. Prof Julie Lovegrove, the director of the Hugh Sinclair Unit of Human Nutrition at the University of Reading, says: 'These foods are not only nutritious but also incredibly versatile, affordable and sustainable.' If you want to start eating more pulses, here are 15 things you need to know. You don't have to cook pulses for hours. 'Don't be put off by the idea that you have to soak dried pulses in advance,' says Maidment. 'I am rarely organised enough to do so, but thankfully there's a huge range of jarred and canned varieties that require no prep and are hugely convenient. If you can afford to spend a bit more, then jarred varieties have the edge over canned in terms of flavour and texture. Brands such as Bold Bean Co, Brindisa or Belazu are consistently excellent.' But batch-cooking dried pulses is the best value. Jenny Chandler, the author of Super Pulses and Pulse, soaks and cooks a big pot of pulses once a week. 'You will finish up with well over double their volume – it's a really economical way to have a ready supply. They will keep in their cooking water for five days in the fridge and you can freeze any leftovers. Use them in salads, soups, purees, curries, stews and even puddings – they will become the bedrock of your cooking.' Pulses are for everyone. 'You do not have to be vegetarian or vegan to enjoy pulses – far from it,' says Maidment. 'We should all be eating more pulses. For instance, in a traybake, I'll use one chicken thigh per person instead of two, and add a can of chickpeas or butter beans. I often add a can of lentils to bolognese. You're still getting filling protein, but with the added benefits of gut-friendly fibre and numerous other minerals, vitamins and antioxidants.' They make meals go much further. 'Most pulses are relatively cheap and quite mild in taste, making them ideal for bulking out soups, stews and curries without affecting the original flavour,' says Maidment. 'You can often use different varieties interchangeably, depending on what you have to hand.' Chandler adds a handful of cooked pulses to all sorts of dishes. 'Throwing a few chickpeas or cannellini beans into a simple tomato sauce with pasta not only ups the nutritional profile, but also keeps you feeling full for much longer,' she says. Baked beans are just the beginning. 'By far the most eaten pulse in the UK is the haricot bean due to its starring role in tinned baked beans,' says Maidment. 'Butter beans, cannellini beans, black beans and kidney beans are also popular, but there is a huge variety of beans to try. For instance, flageolet beans are delicate, pale-green beans popular in French cooking – try them in a slow-braised lamb stew with garlic, thyme and white wine.' Chandler loves yin yang beans, AKA calypso or orca beans. 'These black and white beans are utterly beautiful and taste wonderful in chilli,' she says. But beans on toast still rules. 'My favourite pulse-based dish is garlicky beans and bitter greens on toast, topped with chilli oil,' says Joe Yonan, the author of Cool Beans. You can make (almost) anything with chickpeas. 'The chickpea is my favourite pulse, for its versatility,' says Yonan. 'It is the basis of hummus, the best dip on the planet. It's great in a coronation chickpea sandwich, and it holds its shape in salads and stews.' For a snack, Yonan mixes cooked chickpeas with olive oil and spices (such as za'atar, Chinese five spice, chaat masala or smoked paprika) and roasts them in the oven for an hour at 150C/300F. 'I then turn off the oven but leave them in there to completely cool – it dries them out and makes them really satisfyingly crunchy.' He also uses chickpea (AKA gram) flour to make farinata or socca, a savoury pancake; panisse (chickpea fries); and bhajis and pakoras. 'Sometimes I use it as a base for a sort of non-traditional, don't-tell-the-Italians pizza.' Lentils cook more quickly than most pulses. Red split lentils are especially quick, cooking in about 15 minutes. Lentils don't need soaking, but it does reduce the cooking time. Maidment likes to experiment with different dals. 'Regional Indian dals can be made with a range of lentils – yellow moong, black urad, chana dal – each bringing a slightly different flavour and texture,' says Maidment. But she also has a soft spot for tinned lentils. 'I often roast drained, tinned lentils with olive oil and crushed garlic to boost their flavour and add crispness before throwing them into a salad – perhaps ricotta and prosciutto, or chopped fresh and sun-dried tomatoes, mozzarella and basil.' Pulses make delicious dips. 'Hummus is the classic, but you can blend most pulses into dips,' says Maidment. 'Fava, a fabulous Greek split yellow pea dip, is absolutely worth making.' Blend cooked split yellow peas with caramelised onions and garlic, lemon juice, olive oil, salt and a little of the beans' cooking liquor or water to make. Pulse liquid has many uses. 'Jarred and canned pulses are usually stored in a liquid known as aquafaba,' says Maidment. 'It can be great for adding creaminess to savoury dishes or used as an egg alternative in baking.' She advises checking the salt levels and ingredients list before using – some pulses have added preserving and firming agents. Black beans make the best veggie burgers, says Yonan. The Guardian's Meera Sodha agrees. She mashes a drained tin of black beans with breadcrumbs, garlic and onion powders, chipotle paste, dijon mustard, tomato ketchup and a splash of aquafaba, shapes them into patties, then fries them in olive oil until crispy. British pulses are having a revival. Maidment and Chandler both recommend carlin peas, pleasingly also known as black badgers, which are a heritage British pulse. They are available dried and cooked from companies such as Hodmedod's. 'They're small, nutty brown peas, and make a great alternative to chickpeas, with a similarly impressive nutrient profile,' says Maidment. She roasts cooked carlin peas until crispy, then adds them to salads such as quinoa, broccoli and halloumi. Chandler uses them in dips and curries, and to make a version of refried beans. 'They're much more versatile than yellow or green dried peas as they don't have such a pronounced 'pea' flavour,' she says. In the US, Yonan suggests the lady pea, a spherical white bean that is popular in southern cuisine. Pulses make great protein shakes. 'A handful of cooked pulses added into a smoothie will give it a great creamy texture and make it more nourishing,' says Chandler. She adds black beans or borlotti beans to dark berry smoothies, and chickpeas, cannellini beans or butter beans to green smoothies. Pulse-based pasta is worth a try. There is an increasing range of high-fibre pasta made from pulse flour: peas, lentils, chickpeas, black beans, mung beans … Chandler enjoys this alternative pasta, but says she doesn't use it in classical Italian dishes: 'I may use it in a pasta salad, say, or team it with a blue cheese and walnut sauce.' Yonan agrees that pulse pasta is best paired with 'pungent flavours – super-garlicky or spicy'. Pulses aren't just for savoury dishes. Yonan makes a chocolate and chickpea tart, and adds adzuki beans to brownies. 'Adzuki beans are used in a lot of Asian desserts, such as mochi and ice-cream,' he says. Maidment prefers to use kidney beans in her brownies, while Chandler has a recipe for a simple chocolate and cannellini bean mousse. Drain and retain the liquid from a tin of cannellini beans. Blitz the beans with 150g of melted dark chocolate and an optional tablespoon of cocoa powder. Whisk the liquid for five to 10 minutes, until frothy. Fold into the melted chocolate and bean mix, and sweeten with a couple of tablespoons of maple or date syrup. Chill the mix before eating, perhaps topped with some chopped stem ginger in syrup, or served with fresh raspberries. Do you have an opinion on the issues raised in this article?
