Governing ghostbots - ScienceDirect - 0 views

  •  
    "This article discusses the legal implications of a novel phenomenon, namely, digital reincarnations of deceased persons, sometimes known as post-mortem avatars, deepfakes, replicas, holographs, or chatbots. To elide these multiple names, we use the term 'ghostbots'. The piece is an early attempt to discuss the potential social and individual harms, roughly grouped around notions of privacy (including post-mortem privacy), property, personal data and reputation, arising from ghostbots, how they are regulated and whether they need to be adequately regulated further. For reasons of space and focus, the article does not deal with copyright implications, fraud, consumer protection, tort, product liability, and pornography laws, including the non-consensual use of intimate images ('revenge porn'). This paper focuses on law, although we fully acknowledge and refer to the role of philosophy and ethics in this domain."

The big idea: should we worry about sentient AI? | Science and nature books | The Guardian - 0 views

  •  
    "No surprise, then, that Twitter is aglow with engineers and academics mocking Lemoine for falling into the seductive emptiness of his own creation. But while I agree that Lemoine has made a mistake, I don't think he deserves our scorn. His error is a good mistake, the kind of mistake we should want AI scientists to make."

How digital twins may enable personalised health treatment | Medical research | The Gua... - 0 views

  •  
    "Imagine having a digital twin that gets ill, and can be experimented on to identify the best possible treatment, without you having to go near a pill or a surgeon's knife. Scientists believe that within five to 10 years, "in silico" trials - in which hundreds of virtual organs are used to assess the safety and efficacy of drugs - could become routine, while patient-specific organ models could be used to personalise treatment and avoid medical complications. Digital twins are computational models of physical objects or processes, updated using data from their real-world counterparts. Within medicine, this means combining vast amounts of data about the workings of genes, proteins, cells and whole-body systems with patients' personal data to create virtual models of their organs - and eventually, potentially their entire body"

Millions of new materials discovered with deep learning - Google DeepMind - 0 views

  •  
    "AI tool GNoME finds 2.2 million new crystals, including 380,000 stable materials that could power future technologies Modern technologies from computer chips and batteries to solar panels rely on inorganic crystals. To enable new technologies, crystals must be stable otherwise they can decompose, and behind each new, stable crystal can be months of painstaking experimentation. Today, in a paper published in Nature, we share the discovery of 2.2 million new crystals - equivalent to nearly 800 years' worth of knowledge. We introduce Graph Networks for Materials Exploration (GNoME), our new deep learning tool that dramatically increases the speed and efficiency of discovery by predicting the stability of new materials."

Prof Nita Farahany: 'We need a new human right to cognitive liberty' | Neuroscience | T... - 0 views

  •  
    "To start we need a new human right to "cognitive liberty", which would come with an update to other existing human rights to privacy, freedom of thought and self-determination. All told it would protect our freedom of thought and rumination, mental privacy, and self-determination over our brains and mental experiences. It would change the default rules so we have rights around the commodification of our brain data. "

Google DeepMind and Isomorphic Labs introduce AlphaFold 3 AI model - 0 views

  •  
    "In a paper published in Nature, we introduce AlphaFold 3, a revolutionary model that can predict the structure and interactions of all life's molecules with unprecedented accuracy. For the interactions of proteins with other molecule types we see at least a 50% improvement compared with existing prediction methods, and for some important categories of interaction we have doubled prediction accuracy."

Microsoft's AI speech generator VALL-E 2 'reaches human parity' - but it's too dangerou... - 0 views

  •  
    "Microsoft researchers said VALL-E 2 was capable of generating "accurate, natural speech in the exact voice of the original speaker, comparable to human performance," in a paper that appeared June 17 on the pre-print server arXiv. In other words, the new AI voice generator is convincing enough to be mistaken for a real person - at least, according to its creators."

Kids who use ChatGPT as a study assistant do worse on tests | Popular Science - 0 views

  •  
    "Researchers at the University of Pennsylvania found that Turkish high school students who had access to ChatGPT while doing practice math problems did worse on a math test compared with students who didn't have access to ChatGPT. Those with ChatGPT solved 48 percent more of the practice problems correctly, but they ultimately scored 17 percent worse on a test of the topic that the students were learning. "

New AI algorithm flags deepfakes with 98% accuracy - better than any other tool out the... - 0 views

  •  
    "With the release of artificial intelligence (AI) video generation products like Sora and Luma, we're on the verge of a flood of AI-generated video content, and policymakers, public figures and software engineers are already warning about a deluge of deepfakes. Now it seems that AI itself might be our best defense against AI fakery after an algorithm has identified telltale markers of AI videos with over 98% accuracy."

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."

Charter school is replacing teachers with AI | Popular Science - 0 views

  •  
    Instead, affiliate charter schools seek applicants for positions like a "High School Guide." These $50/hr employees will help design "creative, immersive learning experiences that teach students to leverage cutting-edge AI tools and innovative strategies," among other responsibilities. "Think of yourself as a brand consultant for 50 startups simultaneously, guiding diverse branding needs from business to personal expertise positioning," reads one job listing. Apart from students' brand development, the opening also stipulates candidates must possess "demonstrated expertise in social media management, content creation, and audience engagement."

AI tries to cheat at chess when it's losing | Popular Science - 0 views

  •  
    "Despite all the industry hype and genuine advances, generative AI models are still prone to odd, inexplicable, and downright worrisome quirks. There's also a growing body of research suggesting that the overall performance of many large language models (LLMs) may degrade over time. According to recent evidence, the industry's newer reasoning models may already possess the ability to manipulate and circumvent their human programmers' goals. Some AI will even attempt to cheat their way out of losing in games of chess. This poor sportsmanship is documented in a preprint study from Palisade Research, an organization focused on risk assessments of emerging AI systems."

Parents do have favorites - by Jacqueline Nesi, PhD - 0 views

  •  
    "But what about social media posts that offer stories of hope and recovery? Could these types of posts actually prevent suicide? For this experimental study, researchers in Austria created 10 suicide-prevention social media posts from a fictitious influencer. The posts offered stories about recovery from suicidal crises, mental health tips, and life-affirming messages. A total of 354 adult participants were randomly assigned to view these posts, or to view 10 posts totally unrelated to mental health. As expected, participants who were exposed to the suicide-prevention posts reported decreased suicidal thoughts and greater intentions to seek help (e.g., from friends, family, or a professional). This was especially true for those who were already struggling with suicidal thoughts."
