Study reveals previously unknown component of whale songs

Researchers have known for decades that whales create elaborate songs, sometimes projecting their calls for miles underwater. A new study from the Woods Hole Oceanographic Institution (WHOI), however, has revealed a previously ...

Light and sound waves reveal negative pressure

Negative pressure is a rare and challenging-to-detect phenomenon in physics. Using liquid-filled optical fibers and sound waves, researchers at the Max Planck Institute for the Science of Light (MPL) in Erlangen have now ...

The risks of low-speed impacts with liquids

When a solid object hits a liquid, the impact produces shock waves: a process that has long occupied engineers due to its implications for design of hydraulic systems or motors. KAUST researchers now show that impacts at ...
