X-ray imaging reveals how silicon anodes maintain contact in all-solid-state batteries

All-solid-state batteries (ASSBs) using silicon (Si) anodes are among the most promising candidates for high-energy and long-lasting power sources, particularly for electric vehicles. Si can store more lithium than conventional graphite, but its volume expands by roughly 410% during charging. This swelling generates mechanical stress that cracks particles and weakens their contact with the solid electrolyte, disrupting the flow of ions and reducing efficiency.

To address this, a research group led by Professor Yuki Orikasa from the College of Life Sciences, Ritsumeikan University, along with Ms. Mao Matsumoto, a graduate student at the Graduate School of Life Sciences, Ritsumeikan University (at the time), and Dr. Akihisa Takeuchi from the Japan Synchrotron Radiation Research Institute, used operando synchrotron X-ray tomography with nanometer resolution to observe what happens inside these batteries as they charge and discharge in real time.

Their paper is published in ACS Nano.

AI With Integrity: Leading Innovation Responsibly

• Ensuring ethical leadership at all levels.

Ethical considerations must be integrated into every phase of AI development—not added as an afterthought.

As AI transforms business, responsible leadership will unlock new possibilities. Responsible AI is not just about compliance—it is a strategic advantage that builds trust and drives sustainable growth in an era where technology should benefit every part of society. In domains such as supply chain management, local decisions can have global consequences. Ethical AI enables progress that stays true to shared values across all points of influence. Fair, transparent and accountable by design—this is how institutions can trust innovation to build smarter systems and a better world.

Single molecular membrane can make lithium batteries safer and longer-lasting

A team of Korean scientists has developed a separator technology that dramatically reduces the explosion risk of lithium batteries while doubling their lifespan. Like an ultra-thin bulletproof vest protecting both sides, this molecularly engineered membrane stabilizes both the anode and cathode in next-generation lithium-metal batteries.

The joint research, led by Professor Soojin Park and Dr. Dong-Yeob Han from the Department of Chemistry at POSTECH, together with Professor Tae Kyung Lee of Gyeongsang National University and Dr. Gyujin Song of the Korea Institute of Energy Research (KIER), was recently published in Energy & Environmental Science.

Conventional lithium-ion batteries, which power today’s electric vehicles and energy storage systems, are approaching their theoretical energy limits. In contrast, lithium-metal batteries can store about 1.5 times more energy within the same volume, potentially extending an electric vehicle’s driving range from 400 km to approximately 700 km per charge. However, their practical use has been hindered by serious safety issues.

WORLDCHANGING Space Energy Supercharges AI! What it means for Nvidia, Tesla and Other AI Companies

Elon Musk plans to launch solar-powered AI satellites that could provide a nearly limitless source of energy to supercharge AI processing capacity, potentially disrupting traditional energy production and benefiting companies like Nvidia and Tesla ## ## Questions to inspire discussion.

Space Solar Power Economics.

🚀 Q: What’s the projected cost trajectory for space-based solar power? A: SpaceX could achieve $10 per watt for space solar by 2030–2032, down from previously estimated $100 per watt, with ultimate target of $1 per watt for operational systems, requiring 3–4 orders of magnitude cost reduction through Wright’s Law.

💰 Q: How much would launching 1 terawatt of space solar cost? A: Launching 1 terawatt of space solar power requires $1 trillion in launch costs alone, not including manufacturing and operational expenses.

⚡ Q: What energy advantage does space solar have over ground-based systems? A: Space solar plants generate 10x more energy than ground-based sources by operating 24/7 with double intensity, each equivalent to a nuclear power plant in output.

World’s first fast-neutron nuclear reactor to power AI data centers

French startup Stellaria secures its first power reservation from Equinix for Stellarium, the world’s first fast-neutron reactor that reduces nuclear waste.

The agreement will allow Equinix data centres to leverage the reactor’s energy autonomy, supporting sustainable, decarbonized operations and powering AI capabilities with clean nuclear energy.

The Stellarium reactor, proposed by Stellaria, is a fourth-generation fast-neutron molten-salt design that uses liquid chloride salt fuel and is engineered to operate on a closed fuel cycle.

Superconductivity for addressing global challenges

High‑energy physics has always been one of the main drivers of progress in superconducting science and technology. None of the flagship accelerators that have shaped modern particle physics could have succeeded without large‑scale superconducting systems. CERN continues to lead the efforts in this field. Its next accelerator, the High‑Luminosity LHC, relies on high-grade superconductors that were not available in industry before they were developed for high-energy physics. Tomorrow’s colliders will require a new generation of high‑temperature superconductors (HTS) to be able to realise their research potential with improved energy efficiency and long‑term sustainability.

Beyond the physics field, next‑generation superconductors have the potential to reshape key technological sectors. Their ability to transmit electricity without resistance, generate intense magnetic fields and operate efficiently at high temperatures makes them suitable for applications in fields as diverse as healthcare, mobility, computing, novel fusion reactors, zero‑emission transport and quantum technologies. This wide range of applications shows that advances driven by fundamental physics can generate broad societal impact far beyond the laboratory.

The Catalysing Impact – Superconductivity for Global Challenges event seeks to accelerate the transition from science to societal applications. By bringing together top-level researchers, industry leaders, policymakers and investors, the event provides a structured meeting point for technical expertise and strategic financing. Its purpose is not simply to present progress but to build bridges across sectors, disciplines and funding landscapes in order to move superconducting technologies from early demonstrations to impactful applications.

Elon Musk Crazy Answer 🔥 #wealthmindset #motivation

• Context and Explanation — Elon Musk was once asked a wild question: could Tesla ever build an aquatic car?

He admitted that a submarine car” is technically possible — but the market for such vehicle would be tiny. The idea might excite enthusiasts, but practicality and scale matter more than novelty.

This response captures Musk’s core philosophy: just because something is technically possible doesn’t mean it’s worth building. True innovation isn’t about chasing every wild idea — it’s about focusing on what can scale, solve real problems, and reshape entire industries.

Laude × CSGE: Bill Joy — 50 Years of Advancements: Computing and Technology 1975–2025 (and beyond)

From the rise of numerical and symbolic computing to the future of AI, this talk traces five decades of breakthroughs and the challenges ahead.

Bill is the author of Berkeley UNIX, cofounder of Sun Microsystems, author of “Why the Future Doesn’t Need Us” (Wired 2000), ex-cleantech VC at Kleiner Perkins, investor in and unpaid advisor to Nodra. AI.

Talk Details.
50 Years of Advancements: Computing and Technology 1975–2025 (and beyond)

I came to UC Berkeley CS in 1975 as a graduate student expecting to do computer theory— Berkeley CS didn’t have a proper departmental computer, and I was tired of coding, having written a lot of numerical code for early supercomputers.

But it’s hard to make predictions, especially about the future. Berkeley soon had a Vax superminicomputer, I installed a port of UNIX and was upgrading the operating system, and the Internet and Microprocessor boom beckoned.
