Nowadays society is deeply concerned with the safety issues, the flight safety in particular. Despite the technological progress, people can not do without dogs` assistance, as no device is capable of replacing the dogs` scent in search of explosive substances and drugs. Dogs are indispensable for differentiating between different individuals by specific smells. To work efficiently a dog needs excellent scent and ability to learn quickly. It is only in Russia that the unique animals -dog and jackal hybrids - have been bred for this purpose. This effort has been undertaken by Klim Sulimov, Senior Research Assistant, D.S. Likhachev Scientific Research Institute for Cultural Heritage and Environmental Protection.
However, why did the scientists come to the idea of breeding the hybrids? The matter is that wild jackals have a better sense of smell than any dog breeds. In the course of domestication animals have lost a lot of qualities needed for living at large. Along with that, it is hard to work with wild animals: they would never trust people completely and be as obedient as dogs. Besides, jackals endure cold weather pretty badly - unlike their congeners, they perspire from all the skin surface. So, hybridisation has appeared to be the only solution.
The scientists had to choose the dog breed best suited for the purpose. "We have chosen arctic dogs - reindeer herding husky, Sulimov told us. Northern dogs have better sense of smell than all other dog breeds, as huskies are used under severe conditions of arctic cold. Substances become non-volatile under low temperatures, that is why a sense of smell becomes keener." The reindeer herding huskies in the North of Russia help to graze reindeers.

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...

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...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
