TL;DR: An AI model developed by Caristo Diagnostics can now detect heart inflammation that predicts the risk of a heart attack within the next 10 years. The technology, considered "game-changing," is being piloted in five UK hospitals, with a decision on its wider use within the NHS expected soon. This AI-driven tool could significantly reduce heart attack risks by enabling early intervention.
What's the Essence?: The AI model, developed by Oxford University spinout Caristo Diagnostics, identifies heart inflammation invisible to traditional CT scans. This breakthrough technology is currently being tested in five NHS hospital trusts across the UK. By analyzing routine CT scans with the CaRi-Heart AI platform, the system can detect coronary inflammation and plaque, which are linked to a higher risk of cardiovascular disease and fatal heart attacks. The AI model's ability to detect these early signs means that patients can be treated before blockages or narrowings in the heart even develop. This early detection capability has the potential to transform how heart disease is managed, with the technology also being adapted for preventing strokes and diabetes.
How Does It Tick?: The AI model works by analyzing the fat around the coronary arteries in CT scans, measuring inflammation that could indicate a higher risk of heart disease. The AI platform uses an algorithm to detect signs of coronary inflammation, which are then verified by trained operators. Research from the Orfan study, involving 40,000 patients, showed that those with detected inflammation had a 20 to 30 times higher risk of dying from a cardiac event within 10 years. By using this AI technology, nearly half of the at-risk patients were prescribed medication or encouraged to make lifestyle changes, such as quitting smoking or increasing exercise, to mitigate their risk.
Why Does It Matter?: This AI-driven technology marks a significant advancement in the early detection and prevention of heart disease, which affects millions of people in the UK and worldwide. By identifying patients at risk of heart attacks long before traditional methods can, this AI model offers a proactive approach to managing cardiovascular health. The potential rollout of this technology across the NHS could lead to significant cost savings by preventing heart attacks and reducing the burden of heart disease on the healthcare system. Moreover, the AI model's expansion to detect other conditions, like strokes and diabetes, highlights its broader impact on public health.

Second Brain Implant by Elon Musk’s Neuralink
TL;DR: Elon Musk’s Neuralink has implanted a second brain–computer interface (BCI) in a person with a spinal-cord injury. This new implant is an upgraded version aimed at overcoming the glitches encountered with the first device.
What's the Essence?: Neuralink, Elon Musk’s pioneering venture into brain-computer interfaces, has taken a critical step forward with the implantation of a second BCI in a new recipient. Unlike the first implant, which faced issues with thread retraction, this new device boasts several adjustments to improve its performance. The updated implant features 1,024 electrodes, approximately 400 of which are currently providing reliable signals from the brain. These advancements aim to avoid the mechanical problems that hampered the first device, setting a hopeful precedent for future BCI developments.
How Does It Tick?: The second Neuralink BCI, dubbed "Telepathy," involves a coin-sized hub implanted in the skull, from which 64 flexible threads are threaded into the brain’s cortex by a specialized surgical robot. Each thread contains multiple recording sites that capture neural activity, which is then transmitted to an external device via Bluetooth. To counter the setbacks experienced with the first recipient, where the majority of the threads retracted from the brain, Neuralink engineers revamped the recording algorithm to focus on the average activity of neurons rather than individual ones, leading to more stable results. Additionally, the surgical technique was refined to prevent air pockets that could dislodge the electrodes.

Why Does It Matter?: The success of Neuralink’s second BCI is crucial not only for the company but also for the future of human-computer symbiosis. The ability to control devices with thought alone opens up significant possibilities for people with disabilities, providing them with new ways to interact with the world. However, the process also raises ethical concerns and questions about the long-term stability and durability of the implants. While Musk envisions a future where BCIs enable humans to merge with AI, experts caution that achieving this vision requires careful consideration and years of research. Despite the challenges, Neuralink’s progress represents a landmark moment in neurotechnology, with the potential to revolutionize how we connect with machines and, ultimately, how we understand the human mind.

1st Artificial Intelligence Researcher in the World! Tokyo Lab's AI Scientist: 'Sakana AI'
Prompt: "An AI humanoid scientist making researches in their lab, blue-green tones, cyberpunk style"
TL;DR: Sakana AI has introduced the world’s first AI Scientist, an innovative AI model that can autonomously generate ideas, conduct experiments, and write scientific papers, potentially accelerating scientific discovery and transforming research processes.
What's the Essence?: Sakana AI, in collaboration with scientists from the University of Oxford and the University of British Columbia, has introduced "The AI Scientist," the first generative AI model capable of independently conducting scientific research. This groundbreaking model is designed to mimic the entire scientific discovery process—from generating ideas to running experiments and writing research papers. It's a significant step towards automating scientific research, potentially accelerating discoveries across various fields.
How Does It Tick?: The AI Scientist operates by using large language models that simulate the steps involved in scientific inquiry. It begins with ideation, followed by code execution, experimentation, and finally, drafting a complete scientific paper. Remarkably, Sakana AI claims that the model can produce a research paper at the low cost of $15 and that these papers have surpassed the acceptance threshold of a prominent machine learning conference, as judged by an automated review system. The AI also follows a structured research path, utilizing open-source codebases, performing literature reviews, and continuously refining its methods to improve subsequent generations of research.
Conceptual illustration of The AI Scientist. The AI Scientist first brainstorms a set of ideas and then evaluates their novelty. Next, it edits a codebase powered by recent advances in automated code generation to implement the novel algorithms. The Scientist then runs experiments to gather results consisting of both numerical data and visual summaries. It crafts a scientific report, explaining and contextualizing the results. Finally, the AI Scientist generates an automated peer review based on top-tier machine learning conference standards. This review helps refine the current project and informs future generations of open-ended ideation.
Why Does It Matter?: The introduction of The AI Scientist could herald a new era in scientific research, where AI systems can conduct continuous investigations without the limitations of human researchers, such as the need for rest. This could lead to rapid advancements in critical areas like materials science, drug discovery, and climate change mitigation. However, despite its potential, the model is currently limited to AI software development and requires an existing codebase to initiate its research. It also lacks computer vision capabilities and is prone to errors, particularly when writing and evaluating results. While The AI Scientist represents a significant breakthrough in generative AI, it still falls short of achieving the level of creativity and intuition necessary to make genuinely original scientific discoveries.
