By comparing foxes selected for tameness with others that have not been selected in this way, researchers have found evidence that dramatic behavioral and physiological changes accompanying tameness may be associated with only limited changes in gene activity in the brain.
The work is reported by Elena Jazin and colleagues at Uppsala University, the Swedish University of Agricultural Sciences, and the Norwegian University of Life Science.
The first step in the process of domestication in mammals is the selection for tame individuals that can adapt to life with humans and to frequent handling. To investigate the changes in gene activity that accompany tameness, in the present study the authors compared two groups of farm-raised silver foxes (Vulpes vulpes). One group derived from a long-standing domestication process in which farm-raised silver foxes have been selected for more than 40 generations for non-aggressive behavior toward men (see the related work of Brian Hare and colleagues, Current Biology 15:226–230). Another group of foxes was also farm raised but was not selected for tameness. The foxes selected for tameness were docile and friendly and showed developmental, morphological, and neurochemical changes similar to those observed in other domestic animals.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
