NEW CHALLENGE ANNOUNCEMENT Announcing the Energy Arbitrage designed in collaboration with CryptoEconLab It's been on testnet for over a month and live on mainnet next week! So what is energy arbitrage and why does it matter? AI is eating electricity faster than grids can supply it The algorithms that...

🚨 RESEARCHERS JUST MADE WATER-BASED BATTERIES LAST OVER 2,800 HOURS WITH RECORD CAPACITY. A team in South Korea has developed a simple zwitterionic electrolyte additive that dramatically improves the performance of aqueous (water-based) batteries a technology long seen as a safer, cheaper, and more environmentally friendly alternative to lithium-ion. The additive forms tiny nanostructures that guide zinc to deposit evenly on the electrode and create a protective layer that prevents corrosion and unwanted side reactions with water. This solves two of the biggest problems that have limited aqueous batteries: uneven metal buildup and rapid capacity fade. In testing, the modified batteries achieved a world-leading areal capacity of 8.10 mAh cm⁻² and ran stably for more than 2,800 hours. Why this matters: • Aqueous batteries are non-flammable and use abundant, low-cost materials, but have historically suffered from poor lifespan and performance • This approach improves both cycle life and capacity at the same time — something many previous solutions struggled to achieve together • It uses a simple additive rather than requiring expensive new materials or complex manufacturing changes • The technology is particularly relevant for large-scale energy storage needed for renewables and AI data centers The deeper implication: We’re getting closer to making safe, scalable, and affordable grid storage a reality. While lithium-ion still dominates, aqueous batteries could become a strong contender for stationary storage where safety, cost, and longevity matter more than energy density. A small molecular tweak unlocking major performance gains shows how materials engineering at the nanoscale can have outsized real-world impact. This is the kind of incremental but meaningful progress that compounds over time. How important do you think safer, water-based batteries will be for the future energy grid compared to improving lithium-ion or other alternatives?

🚨 SCIENTISTS JUST REPLACED EXPENSIVE PLATINUM CATALYSTS IN ZINC-AIR BATTERIES WITH CHEAP IRON AND IT WORKS BETTER. Zinc-air batteries are one of the most promising low-cost, high-energy-density alternatives to lithium-ion, but they’ve been held back by a slow and inefficient oxygen reduction reaction that usually requires precious metal catalysts. Researchers at Tohoku University engineered a simple iron oxide/samarium oxide interface that dramatically speeds up this reaction. The heterointerface changes how electrons behave at the surface, weakens excessive bonding with reaction intermediates, and delivers faster kinetics plus excellent durability all without any noble metals. The new catalyst performed strongly in both liquid and flexible solid-state zinc-air batteries, successfully powering LEDs and even charging a smartphone. Why this matters: • Zinc-air batteries use oxygen from the air, abundant zinc, and are much cheaper and safer than lithium-ion • Removing the need for platinum or other precious metals makes them far more scalable and affordable • The iron-based interface approach is simple, stable in alkaline conditions, and improves both performance and longevity • It was demonstrated in practical devices, not just lab tests The deeper implication: We’re getting closer to energy storage that doesn’t rely on scarce, expensive materials. Zinc-air technology has long been held back by catalyst limitations, but this work shows that clever interface engineering with cheap, abundant elements can unlock the performance needed for real-world applications from portable electronics to large-scale grid storage. It’s another step toward clean energy systems that are not only sustainable in operation, but also in the materials they use. The future of batteries may not depend on mining more rare metals… but on smarter chemistry with what we already have in abundance. How close do you think we are to zinc-air batteries becoming a mainstream alternative to lithium-ion? Follow for more frontier battery materials and clean energy storage research.

A few points on the Powering Canada Strong announcement that is important to understand; * Doubling Canada's electricity generation capacity is paramount. I just wish it wouldn't take 20+ years. We don't generate enough electricity to be self-sufficient or participate in future industries. We have no choice. Has to be done. It's something I called for a while and spoke on. * Linking the connectivity of Canada's fragmented grid. This is a must to increase productivity, and remove waste. It's a one step back for two steps forward type of investment. * the connection and expansion of the grid is one of the important things we need to do reach mining areas and develop these sectors and for the growth of smaller communities around. The problem with these whole announcement is that it is all net zero based which means it won't necessarily build the most reliable possible grid for the $ and will other ridiculous costs to be carbon tax trading based on the way. It's completely inefficient from capital planning point. Mark Carney says: It will require the spreading of costs over time using our AAA balance sheet so that ratepayers don't pay all of the costs of investments today. That means the government is planning to borrow MASSIVELY! That cost will appear not only in your electricity bill but also in the value of the CAD and interest costs that is already hitting record every single year. This plan is utilizing legitimate needed action to transform all of Canada's energy need into ideological driven carbon tax trade system and inefficient power generation that all together will cost Canadian taxpayers hundreds of billions more than it should.

Yesterday at Brown University ICERM's workshop on “Agentic Scientific Computing and Scientific Machine Learning” I spoke about “Adaptive Swarms Across Scales”, making the case for scientific AI as systems that can create representations, stress them, fracture them, and enlarge the category in which future representations live. The category here is a composable and breakable working universe of science: data, hypotheses, simulations, measurements, tools, failures, figures, papers, provenance, and the transformations that connect them. Discovery happens when those transformations become executable, inspectable, composable, and capable of changing the world model they operate within. Atomistic modeling gives one category - states, forces, trajectories, observables, boundary conditions, conservation laws. Neural surrogates learn fast morphisms inside or between such categories. But discovery is higher-order: it changes which objects and morphisms are available in the first place: what variables exist, what operations are allowed, what evidence counts, what scale is active, what invariant is being preserved, and what kind of explanation the system is even capable of forming. This is scientific method as adaptive architecture: compression, stress, fracture, recomposition. Fracture matters here because it makes the logic physical: a non-commuting diagram realized in matter. The imposed load, material hierarchy, defect field, and assumed continuum description no longer map cleanly into the observed outcome. The crack is the obstruction and it identifies where the old morphism failed and where a new representation must be introduced. The physical crack and the categorical obstruction are the same event viewed in different substrates. ScienceClaw × Infinite is a machine for constructing and transforming a category of scientific artifacts. Each artifact is typed. Each operation has lineage. Each failed branch remains in the category as reusable structure. The “paper” is no longer the terminal object of science; it is one projection of a larger compositional trace, and it can be generated at any time for consumption by a human or an AI. With that the unit of scientific labor is changing. For most of the twentieth century the unit was the result (a measurement, a theorem, a synthesized molecule). It is now becoming the algorithm that produces results, and after that, the substrate of discovery itself. The static PDF is the wrong terminal object for this regime, and the role of the scientist with it. We now design algorithms that build algorithms, and eventually substrates in which such algorithms compose themselves. At that point, the scientist is no longer outside the discovery system. The scientist becomes one of the representations the system can transform. In that sense, the systems will eventually do science to us, and that is the structural consequence of the principle they are built on.
