Helix Carbon has developed a process to convert waste CO2 from blast furnaces into CO, which can then be recycled back into the furnace to reduce coke usage. This tech could cut coke use by up to 33%, saving iron producers $14 per ton of iron. The iron and steel industries, a $2 trillion market, could see significant cost savings and reduced carbon emissions. Helix Carbon's electrolyzer can handle the entire exhaust stream, and the company plans to start with specialty chemicals to bring in early revenue. The tech can also be used to make chemicals on-site from waste streams without capturing CO2 first.
An OpenAI employee was fired and arrested for planting a sophisticated recording device in a conference room to capture sensitive communications. The device, inserted into a USB port on a television, was discovered a week later and contained advanced encryption and audio monitoring capabilities. OpenAI used its internal AI models to understand the device's capabilities. The employee faces up to five years in prison if convicted. The FBI views protecting American SI innovation as a top priority. This incident highlights the growing security concerns in the AI industry, especially around sensitive technology and data. The employee was arrested on October 9, 2025, and had been working at OpenAI since July 2025. Let's dive deeper…

Summary: A Cambridge startup has developed a tabletop fusion device, enabling faster and cheaper experiments. This could lead to a new era of fusion power plants in a decade.
Key Points:
Startup's tabletop fusion device uses lasers to compress fuel targets, enabling up to 80 experiments per day.
Device generates high pressures with relatively low laser power, minimizing the number of lasers required.
Startup recently raised $6.2 million in seed funding led by Azolla Ventures.
Tritium, a rare isotope of hydrogen, sells for $30,000 per gram today.
One recent study predicts a tritium shortage of 28 kilograms by 2054, worth $840 million.
Why it matters: If you're working on fusion power projects, this startup's tabletop device could drastically reduce R&D costs and accelerate timelines. With tritium shortages looming, the ability to produce it locally could be a game-changer for the industry.

Summary: Licube licenses Hirosaki University tech to purify lithium-6, aiming for a $50B market by 2040. Fusion plants need it to produce tritium, but separating it is tough. Licube's tech enriches lithium to 99.995% lithium-6.
Key Points:
Licube licensed tech from Hirosaki University to purify lithium-6, a key component for fusion plants.
Lithium-6 makes up only about 7.5% of natural lithium, making separation difficult and costly.
Licube's tech enriches lithium to at least 99.995% lithium-6, aiming for a $50B market by 2040.
The tech can be used in semiconductor, pharmaceutical, fission reactors, and spacecraft industries.
Licube's core technology is based on the electrolyzer, a device that uses electrical current to drive chemical reactions.
Why it matters: Licube's technology enriches lithium to at least 99.995% lithium-6, crucial for fusion plants to produce tritium. This tech could disrupt multiple industries beyond fusion, including semiconductors and pharmaceuticals, with a market expected to be $50 billion by 2040. Fusion startups and other industries reliant on lithium-6 will benefit from this purification tech.
