Ordinary sound waves—small oscillations of density—can propagate through all fluids, causing the molecules in the fluid to compress at regular intervals. Now physicists have theoretically shown that in one-dimensional ...
A new hybrid energy-harvesting device may one day replace the need for batteries in certain low-power electronics devices. The new device collects ambient wasted energy from both mechanical vibrations and magnetic fields ...
A pair of physicists at Aix-Marseille University has offered a possible way to measure the speed of our own galaxy more accurately as it moves through space. In their paper published in the journal Physical Review Letters, ...
The basic quanta of light (photon) and sound (phonon) are bosonic particles that largely obey similar rules and are in general very good analogs of one another. Physicists have explored this analogy in recent experimental ...
Researchers at the Institute for Agriculture and Trade Policy and GRAIN have released a report titled "Emissions impossible – How big meat and dairy are heating up the planet." The report is a discussion regarding an analysis ...
An international team of researchers has found a way to make solar hydrogen generation more efficient in microgravity environments. In their paper published in the journal Nature Communications, the group describes what they ...
