Thea Energy lands $20M federal grant to build its magnets for fusion reactors | TechCrunch
HTS magnets are costly but important components in any magnetic confinement reactor, one of the two main ways startups are attempting to harness fusion power for commercial purposes. In magnetic confinement reactors, powerful magnetic fields contain and compress plasma, helping to heat the particles until the fuel can fuse and release large amounts of energy. Thea's reactor is based on a design known as a stellarator. Stellarators look like inner tubes that have been twisted and squeezed in ways that help it confine the plasma more effectively. Most stellarators use magnets that are built to mimic those twists and turns, which makes them expensive to manufacture. To minimize manufacturing costs, Thea uses fewer variants. The 12 large magnets that do the heavy lifting are made from four different templates, and the more than 300 smaller magnets used to fine tune the plasma are all identical. They're arrayed around the periphery of the reactor, similar to how pixels are distributed across a computer display....

The Economics of Status
Posted by Mark Field from Substack in Economics
Some people view the world, at least major parts of it, as a zero sum game where one person gains only to the extent that another loses. Starting with this point of view, it is natural enough to see all disagreements as questions of which side you are on. Do you favor workers or employers, landlords or tenants' The alternative is to see disagreements as not only about how to divide up the pie but about how to change its size. It then becomes not only a question of us vs them but also of our arguments vs their arguments, with some hope that one set of arguments will eventually persuade almost everyone. These different viewpoints are reflected, in political rhetoric and political thinking, in the difference between relative and absolute measures. If we define the poor as the bottom ten percent of the income distribution we can be confident that they will always be with us. If we define the poor by the real income of the tenth percentile as of the US in1900 the problem of poverty has been solved for developed countries, since the number of people in them with incomes that low is now close to zero....

Microsoft launches its first cybersecurity model, plus a new agentic cybersecurity system | TechCrunch
Microsoft on Monday launched its first cybersecurity-specialized model alongside a new AI cybersecurity platform at a small event in San Francisco, taking a big swipe at major players in the space ' namely Anthropic, Google, and OpenAI. The company describes MAI-Cyber-1-Flash as a model that's built 'to find challenging vulnerabilities in complex codebases.' The model is built to animate MDASH, Microsoft's harness dedicated to software vulnerability identification and remediation. The new security platform is dubbed Perception, and it's designed to deploy teams of agents to assist with and automate various security workflows, including identifying and remediating bugs. The platform can also integrate with MDASH. 'We're very very excited to announce our results,' said Mustafa Suleyman, the co-founder of DeepMind and current CEO of Microsoft AI. 'We have MAI-1 Cyber Flash binded [sic] with GPT 5.4 inside of the MDASH harness ' which beats out Gemini, GPT 5.5 Cyber, GPT 5.6 Sol, and Mythos 5 on Cyber Gym, which is the primary benchmark that we all use. The golden benchmark.'...
