New Graphene Tech Powers Supercapacitors To Rival Traditional Batteries

Engineers have achieved a major milestone in the global effort to design energy storage systems that combine high speed with strong power output, opening new possibilities for electric vehicles, grid stabilization, and consumer electronics.

In a paper recently published in Nature Communications, the research team introduced a new type of carbon-based material that enables supercapacitors to store as much energy as traditional lead-acid batteries while delivering power at a much faster rate than conventional battery systems.

Severe solar storms may trigger widespread auroras and disrupt communications this week

Space weather forecasters issued an alert on Tuesday for incoming severe solar storms that could produce colorful northern lights and temporarily disrupt communications.

In the past few days, the sun has burped out several bursts of energy called that could reach Earth Tuesday night and early Wednesday. The potential severe geomagnetic storms could disrupt radio and GPS communications, according to forecasters with the National Oceanic and Atmospheric Administration.

How bright the auroras are and how far south they are visible will depend on when the solar bursts get here and how they interact with Earth’s atmosphere. The vibrant displays could be visible across much of the northern U.S., and as far south as Alabama and Northern California.

MIT quantum breakthrough edges toward room-temp superconductors

MIT scientists uncovered direct evidence of unconventional superconductivity in magic-angle graphene by observing a distinctive V-shaped energy gap. The discovery hints that electron pairing in this material may arise from strong electronic interactions instead of lattice vibrations.

Q&A: Chiral phonons research offers new ways to control materials

The rapidly growing field of research on chiral phonons is giving researchers new insights into the fundamental behaviors and structures of materials. The chirality of phonons could pave the way for new methods to control material properties and to encode information at the quantum level, which has implications for, among other areas, quantum technologies, electronics, energy transport, and sensor technology.

A recently published perpsective article in Nature Physics describes the development of this emerging research area, presents a framework for the classification of phonons, and provides a comprehensive overview of the materials in which chiral phonons have been studied or may be discovered in the future. This work is helping accelerate progress in one of today’s fastest-growing areas of quantum materials.

Matthias Geilhufe, Assistant Professor at the Department of Physics, conducts research on chiral phonons and is one of the main authors of the article.

New recharge-to-recycle reactor turns battery waste into new lithium feedstock

As global electric vehicle adoption accelerates, end-of-life battery packs are quickly becoming a major waste stream. Lithium is costly to mine and refine, and most current recycling methods are energy- and chemical-intensive, often producing lithium carbonate that must be further processed into lithium hydroxide for reuse.

Inexpensive materials transform waste carbon into energy-rich compounds

Turning waste carbon into useful products is a vital part of sustainable manufacturing. Recycling carbon dioxide creates carbon monoxide, which through electricity can be converted into energy-rich compounds. However, existing devices for this process use anion exchange membranes that break down over time when exposed to organic materials, making them less effective.

A team of researchers, led by Feng Jiao, the Lauren and Lee Fixel Distinguished Professor in the McKelvey School of Engineering at Washington University in St. Louis, has found that inexpensive and robust materials, porous separators called diaphragms, can be viable alternatives to these membranes in the conversion process.

After testing various diaphragms, they found that some of them performed as well or better than polymer-based commercial membranes in various operating conditions.

California Needs Supercities—and We Should Build Them Now

My latest, part of my CA Gov run!

These cities could also confront two of California’s biggest crises: homelessness and housing affordability. We could plan from day one for low-income and permanent supportive housing, integrated into neighborhoods rather than hidden on the margins. Additionally, for young people, who have watched the dream of owning a home slip away, these new cities could offer a real future—places where the middle class can afford to live, not just survive.

Supercities would also allow us to build sustainability into the foundation of urban life. Powered by renewable energy, designed around walkability and transit, and filled with parks, green roofs and cutting-edge architecture, they could show the world that growth and environmental responsibility can coexist. California has always been a leader in innovation. Why not apply that same imagination to how we live?

This isn’t fantasy—it’s pragmatism. California’s housing shortage is measured in millions of units. Fixing that within the current system is nearly impossible. Building new cities from scratch is the cleanest, fastest way to meet the scale of the problem. It would put people to work, attract investment and reignite the sense of purpose that once defined this state.

The choice is simple: stagnation or creation. We can let our cities decay under the weight of overregulation and paralysis, or we can build new ones that embody the California ideal of progress. The state that built Silicon Valley, Hollywood and the Golden Gate Bridge shouldn’t be afraid to build again. Supercities aren’t some futuristic fantasy—they’re the bold, realistic solution California needs to revive its economy, house its people and remind the world what ambition looks like.

New Quantum Battery Could Revolutionize Energy Storage

Scientists have designed a topological quantum battery that can charge efficiently without losing energy, using the unique properties of quantum mechanics and topology.

Their research suggests dissipation, long considered harmful, might actually boost power in these next-generation batteries.

Scientists create new bullet-proof fiber that is stronger and thinner than Kevlar

Kevlar has met its match. For decades, it has been the gold standard for impact protection, from bulletproof vests to armored vehicles, and is still widely used. But scientists have now developed a new composite material that is stronger, tougher and better at stopping bullets than Kevlar even though it is much thinner. Their study is published in the journal Matter.

To stop high-speed impacts, like a bullet, a material needs to resist breaking under force () and be able to absorb a lot of energy without shattering or failing (high toughness). However, there is a problem with current solutions, such as Kevlar, which is made from aramid fibers. When scientists try to make these fibers stronger, they often become more brittle, making it difficult to achieve both simultaneously. This is a common trade-off in materials science when you try to improve a material’s overall performance.
