Northern lights glimmer with unexpected trait
An international team of scientists has detected that some of the glow of Earth's aurora is polarized, an unexpected state for such emissions. view more (2008-04-28)
How long is a day on Saturn?
Measuring the rotation period of a rocky planet like the Earth is easy, but similar measurements for planets made of gas, such as Saturn, pose problems. view more (2006-05-04)
New understanding for superconductivity at high temperatures
An international research team has discovered that a magnetic field can interact with the electrons in a superconductor in ways never before observed. view more (2008-01-14)
New, intelligent materials for use in mechanical actuators
A research team at the Department of Physics at the Public University of Navarre are developing new, "intelligent" materials which have the capacity for changing shape when a magnetic field is applied to them. These materials may be used for the generation of ultrasonic signals, in the manufacture of loudspeakers and sonars or in... view more... (2004-01-29)
Is it safe to go shopping?
Surveillance systems and devices that deactivate magnetic security tags at checkouts must limit the strength of their magnetic fields for safety reasons, according to research published today in the Institute of Physics journal Physics in Medicine and Biology. Researchers from the University of Utah investigated the effect of surveillance devices... view more... (2001-10-03)
Giant eruption reveals 'dead' star
An enormous eruption has found its way to Earth after travelling for many thousands of years across space. Studying this blast with ESA's XMM-Newton and Integral space observatories, astronomers have discovered a dead star belonging to a rare group: the magnetars. view more (2009-06-17)
Creation of a magnetic field in a turbulent fluid
Understanding the origin and behavior of the magnetic fields of planets and stars is the goal of research being carried out by many teams from all over the world. view more (2007-03-12)
The first 3 Teslas magnetic resonance imager for research
The University Hospital at the University of Navarra and the Applied Medicine Research Centre (CIMA) of the University has recently acquired a 3 Teslas magnetic resonance imager for joint use, the first for research applications in Spain. view more (2006-10-27)
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)
Geomagnetic Field And The Sex Of A Child
Researchers from St. Petersburg have ascertained that formation of a child's sex depends, among other things, on the geomagnetic field status at the time of conception. view more (2005-03-25)
Metal Foam Has a Good Memory
In the world of commercial materials, lighter and cheaper is usually better, especially when those attributes are coupled with superior strength and special properties, such as a material's ability to remember its original shape after it's been deformed by a physical or magnetic force. view more (2007-12-21)
Thermal treatment for magneto-resistant materials design
Reader heads of compact discs and computer hard discs or position and magnetic field sensors are some of the applications of magneto-resistant materials, which are normally obtained by costly methods. Precisely in order to solve this problem, university teacher Mar'a Luisa Fern'ˇndez-Gubieda Ruiz, of the University of the Basque Country, is... view more... (2003-07-09)
A young pulsar shows its hand
A small, dense object only twelve miles in diameter is responsible for this beautiful X-ray nebula that spans 150 light years. view more (2009-04-06)
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)
Glowing Accolade For Scottish Solar Physicist
A University of St Andrews solar physicist has been awarded one of the world's most prestigious accolades for his shining contribution to solar theory. Professor Eric Priest of the School of Mathematics and Statistics was this week awarded the Hale Prize 2002, usually awarded every two years by the American Astronomical Society (AAS). It is the... view more... (2002-06-07)
Magnetic microchip signals new direction in computing
Durham University scientists have successfully carried out a basic computer operation using a magnetic microchip - a major step along the way to establishing a new generation of electronics and computer technology. They are working in the rapidly growing field of nanotechnology, harnessing the magnetic properties of electrons, rather than their... view more... (2002-06-11)
Superconducting nanowires show ability to measure magnetic fields
By using DNA molecules as scaffolds, scientists have created superconducting nanodevices that demonstrate a new type of quantum interference and could be used to measure magnetic fields and map regions of superconductivity. view more (2005-06-16)
Probing a rare material spin state at NIST
A team of international physicists that includes researchers from the National Institute of Standards and Technology (NIST) has found experimental evidence of a highly sought-after type of arrangement of atomic magnetic moments, or spins, in a series of materials. view more (2007-09-17)
Researchers closer to the ultimate green 'fridge magnet'
Scientists are a step closer to making environmentally-friendly 'magnetic' refrigerators and air conditioning systems a reality, thanks to new research published today in Advanced Materials. view more (2009-05-18)
Iron 'snow' helps maintain Mercury's magnetic field, scientists say
New scientific evidence suggests that deep inside the planet Mercury, iron "snow" forms and falls toward the center of the planet, much like snowflakes form in Earth's atmosphere and fall to the ground. view more (2008-05-08)
