Atlantic expeditions uncover secret sex life of deep-sea nomads

For centuries scientists have thought of deep-sea pelagic fish as nomadic wanderers, in part because information about them was so limited. However, new results from the ongoing Mid-Atlantic Ridge Ecosystems program (MAR-ECO), a Sloan Foundation-sponsored component of the Census of Marine Life, have revealed that these fishes may in fact be gathering at features such as ridges or seamounts to spawn. The research has important implications for how deep-sea ecosystems should be managed to prevent devastation by deep trawling activities. MAR-ECO research expeditions have also led to the discovery of as many as six fish species new to science and the collection of some unusually large deep-sea fish specimens.
The first public presentations of results from MAR-ECO will be made at the Ocean Sciences Meeting in Honolulu (http://www.agu.org/meetings/os06/), from Feb. 20- 24. On Tuesday, Feb. 21, Tracey Sutton, a fish expert at Harbor Branch Oceanographic Institution will be discussing the MAR-ECO deep-sea pelagic fish research at a 9:00 a.m. Hawaii Std. Time (2:00 p.m. EST) press conference and at a 2:15 p.m. Hawaii Std. Time (7:15 p.m. EST) scientific session.

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...
'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...
