PFAS-free membrane with nanoscopic plugs enables cleaner, cheaper hydrogen production

Hydrogen is already an important source of energy. The $250 billion industry supports fertilizer production, steel manufacturing, oil refining, and dozens of other vital activities. While nearly all hydrogen produced today is created using carbon-intensive methods, researchers are racing to develop cheaper ways of producing hydrogen with a lower carbon footprint.

One of the most promising approaches is , a process that uses electricity to power a reactor—called an electrolyzer—to split water (H2O) molecules into hydrogen (H2) and oxygen (O2).

Electrolyzers rely on a that blocks O2 and H2 molecules while allowing positively charged —called protons—to pass through.

When Electrons Sing in Harmony: Geometry-Driven Quantum Coherence in Kagome Crystals

In a groundbreaking experiment that blurs the line between physics and art, researchers at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg have discovered a mesmerizing form of collective quantum behavior in Kagome crystals — a class of materials named after a traditional Japanese basket-weaving pattern. The study, published in Nature, reveals that electrons within these star-shaped lattices can synchronize like singers in a choir, producing a coherent “quantum song” that depends directly on the crystal’s geometric shape.

Quantum Coherence Beyond Superconductivity

Quantum coherence — the synchronized motion of particles acting as overlapping waves — is typically restricted to exotic states such as superconductivity, where electrons pair up and flow without resistance. In normal metals, this delicate coherence is quickly destroyed by scattering and collisions. But in the Kagome metal CsV₃Sb₅, the MPSD team observed something extraordinary: electrons maintained long-range coherence even without superconductivity.

Calorimetric experiment achieves tightest bound on electron neutrino mass

In a Physical Review Letters study, the HOLMES collaboration has achieved the most stringent upper bound on the effective electron neutrino mass ever obtained using a calorimetric approach, setting a limit of less than 27 eV/c² at 90% credibility.

This result validates a decades-old experimental vision and demonstrates the scalability needed for next-generation neutrino mass experiments.

While oscillation experiments have measured the differences between neutrino mass states, the actual individual mass values—the absolute neutrino mass scale—remain unknown. Pinning down these values would help complete our understanding of the Standard Model of particle physics.

Researchers realize a driven-dissipative Ising spin glass using a cavity quantum electrodynamics setup

Spin glasses are physical systems in which the small magnetic moments of particles (i.e., spins) interact with each other in a random way. These random interactions between spins make it impossible for all spins to satisfy their preferred alignments; a condition known as ‘frustration.

Researchers at Stanford University recently realized a new type of spin , namely a driven-dissipative Ising spin glass in a (QED) . Their paper, published in Physical Review Letters, is the result of over a decade of studies focusing on creating spin glasses with cavity QED.

“Spin glasses are a general model for , and specifically for neural networks—spins serve as neurons connected by their mutually frustrating interactions,” Benjamin Lev, senior author of the paper, told Phys.org.

Sunlight split in two: Organic layer promises leap in solar power efficiency

In the race to make solar energy cheaper and more efficient, a team of UNSW Sydney scientists and engineers have found a way to push past one of the biggest limits in renewable technology.

Singlet fission is a process where a single particle of light—a photon—can be split into two packets of energy, effectively doubling the electrical output when applied to technologies harnessing the sun.

In a study appearing in ACS Energy Letters, the UNSW team—known as “Omega Silicon”—showed how this works on an that could one day be mass-produced specifically for use with solar panels.

Physicists discover strange spinning crystals that behave like living matter

Spinning crystals that twist, shatter, and rebuild themselves may hold the key to next-generation materials… Physicists have uncovered the fascinating world of “rotating crystals” — solids made of spinning particles that behave in strange, almost living ways. These odd materials can twist instead of stretch, shatter into fragments, and even reassemble themselves.

‘Singing’ electrons synchronize in Kagome crystals, revealing geometry-driven quantum coherence

Physicists at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg have discovered a striking new form of quantum behavior. In star-shaped Kagome crystals—named after a traditional Japanese bamboo-basket woven pattern—electrons that usually act like a noisy crowd suddenly synchronize, forming a collective “song” that evolves with the crystal’s shape. The study, published in Nature, reveals that geometry itself can tune quantum coherence, opening new possibilities to develop materials where form defines function.

Quantum coherence—the ability of particles to move in synchrony like overlapping waves—is usually limited to exotic states such as superconductivity, where pair up and flow coherently. In ordinary metals, collisions quickly destroy such coherence.

But in the Kagome metal CsV₃Sb₅, after sculpting tiny crystalline pillars just a few micrometers across and applying magnetic fields, the MPSD team observed Aharonov–Bohm-like oscillations in electrical resistance. Thus showing that electrons were interfering collectively, remaining coherent far beyond what single-particle physics would allow.

Seeking Signatures of Graviton Emission and Absorption

A proposed experiment may deliver evidence for the emission or absorption of gravitons—an advance that might one day enable gravity to be controlled much like electromagnetism is today.

A major milestone in human development was the transition from passively observing electromagnetic phenomena, such as electric discharges and magnetism, to actively manipulating them. This shift led to a plethora of applications—from power plants to modern electronics. The exquisite control of electromagnetic fields and of their interaction with matter has also yielded deep insights into the fundamental laws of nature, allowing us to test modern theories with remarkable precision. Now Ralf Schützhold of the Helmholtz-Zentrum Dresden-Rossendorf in Germany argues that a similar turning point may be reached for gravity [1]. His approach for manipulating gravity relies on experiments that can control the emission or absorption of gravitons, the hypothetical elementary particles mediating the gravitational interaction in a quantized theory of gravity.
