Nano-layer of ruthenium stabilizes magnetic sensors
A layer of ruthenium just a few atoms thick can be used to fine-tune the sensitivity and enhance the reliability of magnetic sensors, tests at the National Institute of Standards and Technology (NIST) show.   view more (2007-08-06)

Disorder may be in order for 'spintronic' devices
Physicists at JILA are using ultrashort pulses of laser light to reveal precisely why some electrons, like ballet dancers, hold their spin positions better than others—work that may help improve spintronic devices, which exploit the magnetism or "spin" of electrons in addition to or... view more (2007-02-16)

PneuStep — MRI-safe motor makes robotic biopsies possible
Engineers at the Johns Hopkins Urology Robotics Lab report the invention of a motor without metal or electricity that can safely power remote-controlled robotic medical devices used for cancer biopsies and therapies guided by magnetic resonance imaging.   view more (2007-04-09)

New light microscope may help unlock some of cells' secrets
A microscopy technique pioneered with the help of Florida State University's National High Magnetic Field Laboratory has led to the development of a new light microscope capable of looking at proteins on a molecular level.   view more (2006-08-17)

First tunable, 'noiseless' amplifier may boost quantum computing, communications
Researchers at the National Institute of Standards and Technology (NIST) and JILA, a joint institute of NIST and the University of Colorado (CU) at Boulder, have made the first tunable "noiseless" amplifier.   view more (2008-10-16)

Atoms looser than expected
All the atoms in the universe just got looser, at least in the eyes of humans. No, the laws of physics didn't change overnight, but our knowledge of how strong atoms are held together did have to be readjusted a bit in light of a new experiment conducted at Harvard University.   view more (2006-08-16)

Paramecia Adapt Their Swimming to Changing Gravitational Force
For many single-celled organisms living in water, the force is always against them. The classic example is the slipper-shaped paramecium, which consistently swims harder going up than going down, just to keep from sinking.   view more (2006-09-19)

UK glaciologists warn of global warming threat to South American World Heritage Site
Leading UK scientists fear that one of South America's leading natural tourist destinations, the San Rafael Glacier in Patagonian Chile, which is renowned for the spectacular way in which it releases icebergs into the San Rafael Laguna, may soon retreat to a point where it no longer reaches the... view more (2004-04-26)

Using nano-magnets to enhance medical imaging
Nanoscale magnets in the form of iron-containing molecules might be used to improve the contrast between healthy and diseased tissue in magnetic resonance imaging (MRI)—as long as the concentration of nanomagnets is carefully managed.   view more (2007-02-02)

Scientists put the squeeze on electron spins
University of California scientists working at Los Alamos National Laboratory have developed a novel method for controlling and measuring electron spins in semiconductor crystals of GaAs (gallium arsenide).   view more (2005-06-16)

How Refugees And Their Families Contribute To British Life
The positive contribution of refugees and their families to British life will be highlighted at an event organised by the ESRC Families and Social Capital Research Group on June 21 as part of Social Science Week. The discussion entitled Refugees and their families: a national asset, which will be... view more (2004-06-18)

Plants tell caterpillars when it's safe to forage
The world is filled with cues that could influence the daily feeding patterns of an organism. Many plants, for example, respond to foraging damage by releasing specialized chemical signals-volatile organic compounds that evaporate in the air-that attract the forager's natural enemies.   view more (2006-05-16)

Control circuit for future supercomputer to be produced in Finland
The circuit will improve the computational accuracy and efficiency of quantum computers operating at extremely low temperatures.   view more (2004-12-08)

A researcher of UPV/EHU has designed nanomagnets for industry
The PhD, defended by chemist Sonia Moralejo García at the University of the Basque Country (UPV/EHU), achieved a well-defined line for the manufacture of nanomagnets and other magnetic devices of wide industrial application.   view more (2008-02-13)

UT Southwestern allergist offers coping strategies
The good news for allergy sufferers is that springtime mountain cedars and tree pollens have generally subsided. The bad news: It's summertime.   view more (2006-06-14)

New hope for landmine detection
The first steps in a new method of detecting landmines by determining the presence of tiny quantities of the explosive TNT (trinitrotoluene) are described in research published today in the Institute of Physics publication Journal of Physics D. Markus Nolte, Alexei Privalov and Franz Fujara of... view more (2002-04-15)

Cluster hits the magnetic bull's-eye
ESA's spacecraft constellation Cluster has hit the magnetic bull's-eye. The four spacecraft surrounded a region within which the Earth's magnetic field was spontaneously reconfiguring itself.   view more (2006-07-19)

Free-electron laser shines at over 14 kilowatts in the infrared
The most powerful tunable laser in the world just shattered another power record: the Free-Electron Laser (FEL), supported by the Office of Naval Research and located at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility (Jefferson Lab), produced a 14.2 kilowatt (kW)... view more (2006-11-09)

New Treatment Slows Bone Metastasis - Patients survive incurable disease longer
Together with US colleagues researchers from the University of Bonn have developed a new treatment which enables certain types of cancer to be treated more effectively than was previously the case. The radioactive substance becomes particularly concentrated in metastases in the bones and partially... view more (2003-08-05)

UAB Researchers Develop a Model for Optimising the Magnetic Levitation of Superconductors
A research team in the Physics Department at the UAB, formed by Àlvar S' nchez, Carles Navau (also lecturer and researcher at the Escola Universitaria Salesiana de Sarri' ) and Enric Pardo, have developed a complete theoretical model that allows for the detailed study of the magnetic force of... view more (2002-10-01)

The day LISA Pathfinder hung in the balance
At the core of ESA's LISA Pathfinder mission sit two small hearts. Each is a cube, just 5 centimetres across. Together they will allow LISA Pathfinder to lay the foundations for future space-based measurements that investigate the very core of Einstein's General Relativity.   view more (2006-10-12)

New device from CU physicist tests uncertainty principle to unprecedented level — and shows that looks can cool
In the submicroscopic world - the domain of elementary particles and individual atoms - things behave in the strange, counter-intuitive fashion governed by the principles of quantum mechanics.   view more (2006-09-25)

Complementary and alternative therapies show little benefit in treating menopause symptoms
Insufficient evidence exists to support the use of complementary and alternative therapies to relieve menopause-related symptoms.   view more (2006-07-25)

Putting the squeeze on nitrogen for high energy materials
Nitrogen atoms like to travel in pairs, hooked together by one of the strongest chemical bonds in nature. By subjecting nitrogen molecules to extreme temperatures and pressures scientists are getting a new understanding of not only nitrogen but other similar molecules, including hydrogen.   view more (2008-09-04)

Huygens sets off with correct spin and speed
On Christmas Day 2004, the Cassini spacecraft flawlessly released ESA's Huygens probe, passing another challenging milestone for Cassini-Huygens mission. But, with no telemetry data from Huygens, how do we know the separation went well?   view more (2005-01-11)
