Control Of Widely Recognized Distortion May Allow Greater Output At Sandia's Z Machine
2014-01-10 09:33:28

DOE/Sandia National Laboratories A surprising effect created by a 19th century device called a Helmholz coil offers clues about how to achieve controlled nuclear fusion at Sandia National Laboratories' powerful Z machine. A Helmholz coil produces a magnetic field when electrified. In recent experiments, two Helmholz coils, installed to provide a secondary magnetic field to Z's huge one, unexpectedly altered and slowed the growth of the magneto-Rayleigh-Taylor instabilities, an...

Dogs Poop According To The Earth's Magnetic Field
2014-01-03 04:44:08

redOrbit Staff & Wire Reports - Your Universe Online Ever wonder why your dog turns in circles before relieving himself? A new study published Friday in the journal Frontiers in Zoology may hold the answer. The researchers discovered that dogs of a variety of breeds align their bodies with the Earth’s magnetic field before squatting, and even the smallest fluctuations in the magnetic field will affect the dogs’ position. The researchers at Czech University of Life Sciences...

Nanoparticle Magnetic Behavior Could Lead To Even Smaller Digital Memories
2013-12-19 11:32:36

Universitat Autonoma de Barcelona Electronic devices such as mobile phones and tablets spur on a scientific race to find smaller and smaller information processing and storage elements. One of the challenges in this race is to reproduce certain magnetic effects at nanometer scale. An international collaboration of scientists led by researchers from the Universitat Autònoma de Barcelona Department of Physics and the Institut Catala de Nanociencia i Nanotecnologia, and with the...

Making Magnets With Ultra Cold Atoms
2013-11-27 16:53:05

University of Hamburg Magnets have fascinated mankind for millenia. From the Greek philosophers to scientists of the modern era, which saw the rise of quantum mechanics, magnets have been pondered and investigated. Nowadays, they are not only intriguing oddities of nature, but also constitute crucial building blocks of modern technology: Ranging from data storage over medical instrumentation to transportation. And yet, to this day, they continue to puzzle scientists. A novel approach to...

A measuring device for superconductors breaks world records Weizmann Institute scientists have taken a quantum leap toward understanding the phenomenon known as superconductivity: They have created the world’s smallest SQUID – a device used to measure magnetic fields – which has broken the world record for sensitivity and resolution. Superconductivity is a quantum phenomenon that only occurs when certain materials are cooled to extremely low temperatures. Then, they lose all...

Single-atom Bit Forms Smallest Memory In The World
2013-11-18 12:09:44

Karlsruhe Institute of Technology Control of the Magnetic Moment of Single Atoms Is the Key to Compact Data Memories and Quantum Computers One atom equals one bit: According to this design principle, we would like to construct magnetic data memories in the future. Presently, a compound of several million atoms is needed to stabilize a magnetic bit in a way that hard disk data are secure for several years. However, researchers from KIT have just made a big step towards a single-atom...

How Were Biomolecules Able To Form Inside Asteroids?
2013-10-02 04:24:43

redOrbit Staff & Wire Reports - Your Universe Online Scientists from Rensselaer Polytechnic Institute (RPI) in New York have published new research which they claim definitively refutes existing theories as to how the biomolecules were able to form inside of asteroids. Wayne Roberge, a professor of physics at the RPI School of Science, and his colleagues state that they have developed a new theory based on a fuller, more complete understanding of magnetic fields and solar winds in...
