Nature Communications, Published online: 08 September 2026; doi:10.1038/s41467-026-77579-w Topological interface states usually rely on explicit symmetry breaking. Here, authors show that spontaneous symmetry breaking at an acoustic metagrating interface generates topological Jackiw-Rebbi states, enabling robust, highly directional sound radiation.

An analysis of sound-making structures on preserved wings reveals the mating calls of ancient Jurassic insects, re-creating part of an ancient soundscape.

Scientists from Paul Scherrer Institute PSI have used an electric field to reverse the handedness of atomic vibrations known as chiral phonons. Chiral phonons link magnetism with atomic motion. The ability to control them opens new possibilities for phonon-based information technologies.

Beneath the Arctic Ocean is an orchestra featuring natural and human composers, from cracking sea ice and whistling beluga whales to humming shipping-vessel engines. Researchers from MIT Lincoln Laboratory heard some of this cacophony when analyzing data from commercial off-the-shelf sensors that they integrated and deployed in 2024 during the U.S. Navy’s Operation Ice Camp […]

The frozen stretch then held a light pulse as a sound wave for three nanoseconds, with a control pulse of 0.205 nanojoules enough to lift the readout three standard deviations clear of the noise, and separately the authors calculate that a cryogenically cooled highly nonlinear fibre would need 150 times more pump power to reach the same storage figure of merit.

When a New Glenn rocket blew apart at Florida's Cape Canaveral Space Force Station in May, it released ultra-low-frequency sound waves that reached as far as Texas. Researchers estimate that the blast was roughly equivalent to the Chernobyl reactor explosion of 1986.

I’m interested in the link between physics and our own biology specifically related to the brain and its waves. I had a strong visual aura that looked like this and I was wondering if anyone could tell me what’s happening from a physics angle?

The ultrasonic system levitates and steers tiny objects from one side in open air.

A new speaker uses metamaterials and ultrasound to beam audio towards individual listeners, reducing sound leakage while enabling personalised listening in shared spaces without headphones. Researchers at Pohang University of Science and Technology (POSTECH) have developed a highly directional single-element speaker that can beam audio towards an individual listener while reducing unwanted sound …

A century-old trick for tuning musical instruments has been repurposed to power robots that fly, float and steer themselves using nothing but sound waves.

Not just any sound, but specifically Helmholtz resonance. In simple words, it’s the same phenomenon that happens when you blow air across the neck of a bottle. The air trapped inside the bottle vibrates strongly at a certain frequency – that’s why you can hear a humming sound. A glass bottle is an example of […]

This question basically roots to fundamentals of waves which is quite difficult for me to visualize. Hope that I can clear out this confusion based on answers to this question Would be grateful if someone atleast verifies whether my own answer below is correct or not suppose the green line in the image is a string. black dots were drawn to represent particles along the string and the red/blue one…

Harvard researchers enhanced quantum coherence, protecting fragile quantum information within qubits using mechanical vibrations—sound waves.

Scientists have developed a new acoustic levitation technique using an ultrasonic beam capable of levitating and moving small objects in midair over distances of up to 40 cm (16 inches), six times farther than previously achieved using conventional methods. The study, carried out by a research team from the University of Tsukuba in Japan and […]

Baltic Nordic Acoustic Meeting (BNAM) In May 2026, Gothenburg hosted the Baltic Nordic Acoustic Meeting (BNAM), one of the most important conferences on acoustics in the Nordic and Baltic regions. The event took place on 4–6 May at Chalmers University of Technology and brought together researchers, consultants, companies and students from across the region. BNAM […] The post BNAM 2026 in Gothenbu…

A team of physicists at the Harvard John A. Paulson School of Engineering and Applied Sciences has found that a steady stream of sound waves can shield a fragile quantum bit from its own noisy surroundings, nearly tripling how long it holds information.
