Researchers find that one sniff will do for odor discrimination
Rats inhabit a world of smells far beyond our poor powers to discriminate. Thousands of odors that smell the same to us, or that we cannot perceive at all, are quickly recognizable as distinct and meaningful odors to rodents and other animals in which the Nose Knows. But just how quick?
By measuring the speed of smell, researchers at Cold Spring Harbor Laboratory have now found that unlike humans, rats can tell two very similar odors apart with just one sniff. And because its not the Nose that Knows, but rather the brain, such studies of how animals can rapidly and accurately discriminate odors are revealing vital new information about how the human brain processes information, guides behavior, and even enables us to be consciously aware of our own (though less smelly) world, and our own selves.

Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
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...
