The first topological acoustic transistor

Topological materials move electrons along their surface and edges without any loss, making them promising materials for dissipationless, high-efficiency electronics. Researchers are especially interested in using these materials ...

How the Earth's core is like a multi-layered cake

How is our Earth's inner core like a cake? According to Professor Hrvoje Tkalčić and Sheng Wang from The Australian National University (ANU), there are more similarities than you might think.

Physicists discover special transverse sound wave

Can you imagine sound traveling in the same way as light does? A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: The airborne sound wave vibrates transversely and carries both ...

Lego down! Focused vibrations knock over minifigures

A tabletop covered in miniature Lego minifigures. There is a whooshing sound, a pause, and then a single minifigure in the center of the table topples over, leaving the remaining minifigures standing.

Flexible device could treat hearing loss without batteries

Some people are born with hearing loss, while others acquire it with age, infections or long-term noise exposures. In many instances, the tiny hairs in the inner ear's cochlea that allow the brain to recognize electrical ...

Tiny swimming creatures can create big currents in lake water

Lakes are usually pictured as tranquil environments, largely uninfluenced by the enormous tidal power which drives the oceans. But the surface winds that act upon lakes can significantly alter the environment in which many ...

Longitudinal wave

Longitudinal waves are waves that have same direction of oscillations or vibrations along or parallel to their direction of travel, which means that the oscillations of the medium (particle) is in the same direction or opposite direction as the motion of the wave. Mechanical longitudinal waves have been also referred to as compressional waves or compression waves.
