In this breakthrough acoustic experiment, researchers have directly observed anti-Klein tunneling—a quantum-like phenomenon where chiral sound waves are entirely blocked by a barrier. Using a tunable bilayer phononic crystal, the team demonstrated switchable transitions between full transmission and total reflection, mimicking quantum paradoxes with sound. This work confirms a long-standing theoretical prediction and opens new possibilities for topological wave control and quantum-inspired acoustic devices.

Forecasting electricity demand in buildings is now more accurate with Group Encoding (GE), a new method that uses only existing device operation data. Developed by researchers at the Institute of Science Tokyo, the method improved prediction accuracy by 74% in real-world tests. By simplifying high-dimensional binary data, GE supports efficient energy device management, cost reduction, and seamless integration of renewable energy in distributed systems, making it a practical tool for smart energy operation.

Researchers at the University of California, Riverside, have uncovered how to manipulate electrical flow through crystalline silicon, a material at the heart of modern technology. The discovery could lead to smaller, faster, and more efficient devices by harnessing quantum electron behavior.

Physicists from Aalto University in Finland published a transmon qubit coherence dramatically surpassing previous scientifically published records. The millisecond coherence measurement marks a quantum leap in computational technology, with the previous maximum echo coherence measurements approaching 0.6 milliseconds.

Ongoing research into the effect of environmental change on the buzzing of bees reveals that high temperatures and exposure to heavy metals reduces the frequency (and audible pitch) of non-flight wing vibrations, which could have consequences on the effectiveness of bee communication and their role as pollinators.

A radical cation salt of new aromatic compound produced a molecular conductor with three-dimensional conduction pathways. The conduction pathways were based on intermolecular interactions via ethyl groups, which demonstrated that unpaired electrons move in various directions in the solid passing through both aromatic rings and ethyl groups. Such features were related to doubly degenerated narrow bands at the Fermi level, making it a totally different conductor from any known conductors.

Osaka Metropolitan University researchers discovered why chemical reactions slow down under high-power ultrasound. Excessive ultrasonic output distorts waveforms, reducing active bubble formation and reaction rates. The study classifies three reaction regions, offering guidance for optimizing sonochemistry in applications like nanoparticle synthesis and PFAS degradation.
