AI's 'Oppenheimer moment': autonomous weapons enter the battlefield | Artificial intell... - 2 views

  •  
    "The Ukrainian military has used AI-equipped drones mounted with explosives to fly into battlefields and strike at Russian oil refineries. American AI systems identified targets in Syria and Yemen for airstrikes earlier this year. The Israel Defense Forces, meanwhile, used another kind of AI-enabled targeting system to label as many as 37,000 Palestinians as suspected militants during the first weeks of its war in Gaza."

Real criminals, fake victims: how chatbots are being deployed in the global fight again... - 2 views

  •  
    "Kafaar was inspired to turn the tables on telephone fraudsters after he played a "dad's joke" on a scam caller in front of his two kids while they enjoyed a picnic in the sun. With inane chatter, he kept the scammer on the line. "The kids had a very good laugh," he says. "And I was thinking the purpose was to deceive the scammer, to waste their time so they don't talk to others. "Scamming the scammers, if you like." The next day he called his team from the university's Cyber Security Hub in. There must be a better way than his "dad joke" method, he thought. And there had to be something smarter than a popular existing piece of technology - the Lennybot. Before Malcolm and Ibrahim, there was Lenny. Lenny is a doddery, old Australian man, keen for a rambling chat. He's achatbot, designed to troll telemarketers. With a thready voice, tinged with a slight whistle, Lenny repeats various phrases on loop. Each phrase kicks in after 1.5 seconds of silence, to mimic the rhythm of a conversation."

Excess memes and 'reply all' emails are bad for climate, researcher warns | Greenhouse ... - 0 views

  •  
    "When "I can has cheezburger?" became one of the first internet memes to blow our minds, it's unlikely that anyone worried about how much energy it would use up. But research has now found that the vast majority of data stored in the cloud is "dark data", meaning it is used once then never visited again. That means that all the memes and jokes and films that we love to share with friends and family - from "All your base are belong to us", through Ryan Gosling saying "Hey Girl", to Tim Walz with a piglet - are out there somewhere, sitting in a datacentre, using up energy. By 2030, the National Grid anticipates that datacentres will account for just under 6% of the UK's total electricity consumption, so tackling junk data is an important part of tackling the climate crisis. Ian Hodgkinson, a professor of strategy at Loughborough University has been studying the climate impact of dark data and how it can be reduced."

Are you 80% angry and 2% sad? Why 'emotional AI' is fraught with problems | Artificial ... - 0 views

  •  
    ""An emotionally intelligent human does not usually claim they can accurately put a label on everything everyone says and tell you this person is currently feeling 80% angry, 18% fearful, and 2% sad," says Edward B Kang, an assistant professor at New York University writing about the intersection of AI and sound. "In fact, that sounds to me like the opposite of what an emotionally intelligent person would say." Adding to this is the notorious problem of AI bias. "Your algorithms are only as good as the training material," Barrett says. "And if your training material is biased in some way, then you are enshrining that bias in code.""

Researchers fool university markers with AI-generated exam papers | Exams | The Guardian - 0 views

  •  
    "Researchers at the University of Reading fooled their own professors by secretly submitting AI-generated exam answers that went undetected and got better grades than real students. The project created fake student identities to submit unedited answers generated by ChatGPT-4 in take-home online assessments for undergraduate courses. The university's markers - who were not told about the project - flagged only one of the 33 entries, with the remaining AI answers receiving higher than average grades than the students."

  •  
    "Security fears about Chinese influence over Bytedance, TikTok's owner, are undoubtedly part of the reason why UK politicians have been reluctant to get involved, and the political context is also different - Biden is reacting to Donald Trump's social media clout - but US strategists such as Teddy Goff have suggested that building up an army of TikTokers who can share and amplify political messages is vital."

    "A mobile camera will be taken to roads in East Yorkshire and Northern Lincolnshire to catch drivers using phones and those not wearing seat belts. Safer Roads Humber said the camera unit, which is on loan from National Highways, would be in use for a week from Monday 10 June. A spokesperson said: "It uses artificial intelligence (AI) to identify motorists potentially breaking the law."

Mapping the landscape of histomorphological cancer phenotypes using self-supervised lea... - 1 views

  •  
    "Cancer diagnosis and management depend upon the extraction of complex information from microscopy images by pathologists, which requires time-consuming expert interpretation prone to human bias. Supervised deep learning approaches have proven powerful, but are inherently limited by the cost and quality of annotations used for training. Therefore, we present Histomorphological Phenotype Learning, a self-supervised methodology requiring no labels and operating via the automatic discovery of discriminatory features in image tiles. Tiles are grouped into morphologically similar clusters which constitute an atlas of histomorphological phenotypes (HP-Atlas), revealing trajectories from benign to malignant tissue via inflammatory and reactive phenotypes. These clusters have distinct features which can be identified using orthogonal methods, linking histologic, molecular and clinical phenotypes. Applied to lung cancer, we show that they align closely with patient survival, with histopathologically recognised tumor types and growth patterns, and with transcriptomic measures of immunophenotype. These properties are maintained in a multi-cancer study."

UK mother of boy who killed himself seeks right to access his social media | Internet s... - 0 views

  •  
    "A woman whose 14-year-old son killed himself is calling for parents to be given the legal right to access their child's social media accounts to help understand why they died. Ellen Roome has gathered more than 100,000 signatures on a petition calling for social media companies to be required to hand over data to parents after a child has died. Under the current law, parents have no legal right to see whether their child was being bullied or threatened, was looking at self-harm images or other harmful content, or had expressed suicidal feelings online or searched for help with mental health problems."

The woman using AI to bring aid to civilians in war-torn Lebanon - 0 views

  •  
    "The aidbot is a chatbot - a type of AI system designed to communicate with its users online - that links to WhatsApp. It is programmed to ask simple questions about the types of aid people require along with their names and locations. This information is then recorded onto a Google spreadsheet which Hania and her team of unpaid volunteers, made up of friends and family, access to distribute aid such as food, blankets, mattresses, medicine and clothes. Hania used her spare time to build the bot using the website Callbell.eu, which is commonly used by businesses to engage with customers on Meta's platforms such as WhatsApp, Instagram and Facebook messenger. She explains that the bot, which is still being used today, makes distributing aid more efficient as it cuts down the amount of time she spends responding to requests for aid over WhatsApp."

    "One company working on that is Denmark's Corti, which has developed AI that can listen to healthcare consultations, either over the phone or in person, and suggest follow-up questions, prompts, treatment options, as well as automating note taking. Corti says its technology processes about 150,000 patient interactions per day across hospitals, GP surgeries and healthcare institutions across Europe and the US, totalling about 100 million encounters per year. "The idea is the physician can spend more time with a patient," says Lars Maaløe, co-founder and chief technology officer at Corti. He says the technology can suggest questions based on previous conversations it has heard in other healthcare situations."

AI cracks superbug problem in two days that took scientists years - 0 views

  •  
    "A complex problem that took microbiologists a decade to get to the bottom of has been solved in just two days by a new artificial intelligence (AI) tool. Professor José R Penadés and his team at Imperial College London had spent years working out and proving why some superbugs are immune to antibiotics. He gave "co-scientist" - a tool made by Google - a short prompt asking it about the core problem he had been investigating and it reached the same conclusion in 48 hours."

How accurate are the viral TikTok AI POV lab history videos? - 0 views

  •  
    "Murky and misty streets, coughing townsfolk, and the distant toll of a plague doctor's bell all feature in Hogne's most-watched video, which has racked up 53 million views. It has sparked fascination among many, but historian Dr Amy Boyington describes the medieval-themed video as "amateurish" and "evocative and sensational" rather than historically accurate. "It looks like something from a video game as it shows a world that is meant to look real but is actually fake." She points out inaccuracies like the depiction of houses with large glazed windows and a train track running through the town which wouldn't have existed in the 1300s. Historian and archaeologist Dr Hannah Platts has also noticed significant inaccuracies in a video depicting the eruption of Mount Vesuvius at Pompeii. "Due to Pliny the Younger's eyewitness account of the eruption, we know that it didn't start with lava spewing everywhere so to not use that wealth of historical information available to us feels cheap and lazy.""

Grok: Why Musk's chatbot is causing a sensation in India - 0 views

    ""Grok is a new rebel. Asking Grok questions will not put anyone in trouble. The right-wing has also responded by asking questions about Rahul Gandhi. And then it has become a competitive thing. This is not surprising at all," says Mr Sinha of Alt News. "Other AI bots are programmed to give politically correct answers to questions like 'Who's better, Congress or BJP?'. Grok, however, seems to lack that filter and appears unafraid to tackle controversial issues head-on," he adds."

AI tool to check for skin cancer rolled out at London hospital - 0 views

  •  
    "An NHS hospital in west London is pioneering the use of Artificial Intelligence (AI) to help check for skin cancer. Chelsea and Westminster Hospital said its AI technology has been approved to give patients the all-clear without having to see a doctor. Once photos are uploaded to the system, the technology analyses and interprets the images, with 99% accuracy in diagnosing benign cases, the hospital said. Thousands of NHS patients have had urgent cancer checks using the AI tool, freeing up consultants to focus on the most serious cases and bringing down waiting lists. The system conducts the checks in minutes, with medical photographers taking photos of suspicious moles and lesions using an iPhone and the DERM app, developed by UK firm Skin Analytics."
