Ant antennae provide vital ID information, study finds

University of Melbourne scientists have shone a new light into the complexities of ant communication, with the discovery that ants not only pick up information through their antennae, but also use them to convey social signals.

Microfluidic devices gently rotate small organisms and cells

A method to rotate single particles, cells or organisms using acoustic waves in a microfluidic device will allow researchers to take three dimensional images with only a cell phone. Acoustic waves can move and position biological ...

Study shows whales dine with their own kind

For a few weeks in early fall, Georges Bank—a vast North Atlantic fishery off the coast of Cape Cod—teems with billions of herring that take over the region to spawn. The seasonal arrival of the herring also attracts ...

New theory of deep-ocean sound waves may aid tsunami detection

Acoustic-gravity waves are very long sound waves that cut through the deep ocean at the speed of sound. These lightning-quick currents can sweep up water, nutrients, salts, and any other particles in their wake, at any water ...

Absorbing acoustics with soundless spirals

Researchers at the French National Centre for Scientific Research, CNRS, and the University of Lorraine have recently developed a design for a coiled-up acoustic metasurface which can achieve total acoustic absorption in ...

Fruit flies adjust their courtship song based on distance

Outside of humans, the ability to adjust the intensity of acoustic signals with distance has only been identified in songbirds. Research published Feb. 3, 2016 in Neuron now demonstrates that the male fruit fly also displays ...

How noise pollution is changing animal behaviour

Noise pollution, generally an unintended byproduct of urbanisation, transport and industry, is a key characteristic of human development and population growth. In some cases, it is produced intentionally, for example when ...
