Fungus-growing ants practice agriculture and have been doing so for the past 50 million years according to research published in the Jan. 17 issue of Science. These ants not only grow fungus gardens underground for food but also have adapted to handling parasitic "weeds" that infect their crops.
The team of scientists who collaborated on this analysis includes Ted Schultz of the Smithsonian’s National Museum of Natural History, Bess Wong of the Smithsonian Tropical Research Institute, Cameron Currie and Alison Stuart of the University of Kansas, Stephen Rehner of the U.S. Department of Agriculture, Ulrich Mueller of the University of Texas at Austin, Gi-Ho Sung and Joseph Spatafora of Oregon State University, and Neil Strauss of the University of Toronto.
"The ants, garden fungi, and weeds have all been co-evolving since ant agriculture first got started -- that’s around 50 million years of symbiosis," said Dr. Ted Schultz, research entomologist in the Entomology Section of the Smithsonian’s National Museum of Natural History.

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...
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...
