Taking their cue from fish, scientists in the US have built a navigational aid that will help robots and remote sensors find their way around the world`s vast oceans. The team describes its research today in the Institute of Physics publication Journal of Micromechanics and Microengineering.
Fish and many amphibian animals find their way through even the murkiest of waters, navigate raging torrents and spot obstacles, predators and prey using a sensory organ known as the lateral line system. Sometimes known as the fish`s sixth sense, the lateral line is a system of thousands of tiny hair cells that run the length of the fish`s body. The lateral line responds to fluid flow around the fish and allows it to detect obstacles and sense the movement of water even in complete darkness.
Now, electrical engineer Chang Liu, entomologist Fred Delcomyn and their colleagues at the University of Illinois at Urbana-Champaign, USA have developed an artificial lateral line that could give underwater vehicles and robots a sixth sense. Robots equipped with the lateral line system will be able to navigate and feel in water.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
