America Has A Steel Start-Up. Yes, Really - EP 47 Laureen Meroueh
Duration: 01:39:22
December 3, 2025
- Hera Metals has developed a novel, single-step steelmaking process that uses natural gas as a reducing agent, offering significant reductions in cost (up to 30%) and emissions (at least 50%) compared to traditional methods.
- The company's innovative "Flex HRSE" (Flexible Fuel Hydrogen Electric Reduction Smelting) technology allows for the use of various iron ore grades, including lower-quality ores and waste oxides, and is adaptable to hydrogen as a fuel source.
- Hera Metals is also positioned to address supply chain vulnerabilities in the US by producing high-purity iron essential for rare earth magnets, a critical component for defense systems and clean energy technologies.
OpenAI's Research Chief On The Soup Wars, Poker And The Next Models - EP 46 Mark Chen
Duration: 01:38:18
December 1, 2025
- Intense talent recruitment: OpenAI and Meta are engaged in aggressive, even personal, recruitment efforts for top AI talent, with stories of executives personally delivering soup to potential hires.
- Focus on research vision over competition: OpenAI prioritizes long-term research breakthroughs and developing novel paradigms rather than reacting to competitor benchmarks or engaging in a dollar-for-dollar talent war.
- Emerging AI capabilities in science and problem-solving: The conversation highlights AI's growing ability to generate novel scientific knowledge, solve complex mathematical and coding problems, and the potential for AI to revolutionize scientific discovery.
Aliens, AI, and Saving the Planet - EP 43 Will Marshall
Duration: 01:37:56
November 12, 2025
- In the next decade, humanity may witness three significant advancements: the development of Artificial General Intelligence (AGI), the discovery of life beyond Earth and the decoding of animal communications.
- The increasing power and size of telescopes, particularly space-based ones like JWST, are enabling the analysis of exoplanet atmospheres, making the detection of potential biosignatures, such as oxygen, a realistic prospect within the next ten years.
- The development of AI, especially large language models (LLMs) and multimodal models, is revolutionizing the analysis of satellite imagery by enabling natural language queries for real-time earth data, thereby accelerating insights in fields like agriculture, sustainability, and security.
We Shall Finally Map The Brain - EP 36 Andrew Payne
Duration: 01:24:09
October 1, 2025
- E11 Bio is developing technologies to map mammalian brains by making each neuron a unique color through a process that utilizes viral vectors to deliver a stochastic combination of 18 protein variants to each neuron, theoretically allowing for 262,000 unique markers to be identified.
- A major current bottleneck in connectomics is manual neuron tracing through electron microscopy images, but E11's multi-color barcoding and expansion microscopy techniques, as detailed in their recent pre-print study, improve neuron tracing accuracy by approximately an order of magnitude.
- The development of cheaper connectomics techniques could transform the understanding and treatment of brain disorders by allowing researchers to study wiring diagram differences between healthy and disordered brains, potentially uncovering therapeutic targets in cases where genomics alone has fallen short.
This Is: How Neuralink Builds A Head
Duration: 00:01:37
September 19, 2025
- Fran Romano and the Neuralink surgery engineering team create highly realistic, patient-specific 3D models called "proxies" to mimic human anatomy for neurosurgical practice.
- These proxies are created using a variety of techniques, including 3D printing, silicone molding, and hydrogel freezing, utilizing patient CT and MRI scans to ensure anatomical accuracy.
- The use of these proxies allows neurosurgeons to practice complex procedures on a realistic model of a patient's brain before the actual surgery, aiming to reduce surprises and improve surgical outcomes.
Can California Ever Build Again?
Duration: 01:42:57
September 17, 2025
- California's housing market is showing warning signs due to a surge in inventory, with Los Angeles listings nearing decade-high levels.
- Home prices in California are beginning to decline statewide as a direct result of the high cost of buying, with typical home values exceeding $700,000.
- High mortgage rates are exacerbating affordability issues, pushing the average monthly payment in California to approximately $5,100 - significantly more than other states.
The Man Who Changed Policing In America
Duration: 01:29:14
September 10, 2025
- The speaker believes the prosecution effectively proved causation in the case, helped by compelling video evidence.
- While acknowledging the need for continued evolution in policing, the speaker emphasizes that uses of force are rare, and firearms discharges have decreased significantly, cautioning against generalizing from individual cases.
- The speaker suggests that police officers should reflect on their motivations for entering the profession and continue working toward professionalism and community connection, while also stressing the danger of officers being afraid to take necessary enforcement action due to perceived unfair treatment, which would be detrimental to public safety.
The History And Future Of Brain Implants
Duration: 01:31:18
August 27, 2025
- The development of non-invasive Brain Computer Interfaces (BCIs), such as glasses and headsets, is progressing with applications in space exploration (NASA) and assisting individuals with neurodegenerative diseases.
- Invasive BCIs, like those developed by Neuralink, demonstrate the potential for direct brain-computer communication, though ethical concerns surrounding animal testing and human implantation remain.
- BCIs have the capability to not only restore lost function but may also induce structural and functional changes in the brain through consistent use and training.
The Ultimate Bryan Johnson Interview
Duration: 01:13:23
August 20, 2025
- Johnson believes that AI advancements are leading humanity towards a point where immortality, through computational means or otherwise, is achievable.
- Johnson's daily life is structured around identifying and mitigating factors that could shorten his lifespan, incorporating a strict regimen focused on data-driven health optimization.
- Johnson defends his association with figures like RFK Jr. by arguing that the status quo in American healthcare is failing, while expressing openness to change and creative destruction in the pursuit of improved public health.
How North Korea Infiltrated American Companies With Fake Tech Workers
Duration: 01:10:00
August 13, 2025
- North Korean hackers are increasingly infiltrating companies by posing as remote employees, using sophisticated techniques like AI-generated IDs and fabricated resumes to secure high-paying jobs.
- These hackers primarily aim to generate revenue for the North Korean regime, with estimates suggesting they bring in $300 million annually through various cybercrimes.
- Companies must be vigilant as these infiltrations can lead to data theft, ransomware attacks, and broader security breaches, potentially impacting not just the organization but also individual Americans.
