Bats adapt their echolocation calls to noise

Bats find their way acoustically when they are flying by using echolocation calls, often also employing them when hunting for food. A team of scientists from the Max Planck Institute for Ornithology in Seewiesen and the Ludwig-Maximilians-Universität ...

Researchers demonstrate infrared light modulation with graphene

- Research scientists at the U.S. Naval Research Laboratory (NRL) Electronics Science and Technology Division in collaboration with researchers at University at Buffalo-The State University of New York (SUNY) demonstrate ...

The pink noise of water quality

Lakes and streams are an essential supply of freshwater. Monitoring their water quality relies on measuring their chemistry. Researchers from ETH Zürich and the British research institute CEH have discovered that dozens ...

Carbon nanotubes for molecular magnetic resonances

Researchers at ICFO have developed a new technique for measuring very weak forces on a molecular scale. Thanks to the use of carbon nanotubes, they have achieved the highest level of sensitivity to date. These results published ...

Hair sensor uncovers hidden signals

An "artificial cricket hair" used as a sensitive flow sensor has difficulty detecting weak, low-frequency signals – they tend to be drowned out by noise. But now, a bit of clever tinkering with the flexibility of the tiny ...

How do cold ions slide

Things not always run smoothly. It may happen, actually, that when an object slides on another, the advancement may occur through a 'stop and go' series in the characteristic manner which scientists call "stick-slip", a pervasive ...
