Scientists Discover Magnetic Superatoms
A team of Virginia Commonwealth University scientists has discovered a 'magnetic superatom' - a stable cluster of atoms that can mimic different elements of the periodic table - that one day may be used to create molecular electronic devices for the next generation of faster computers with larger memory storage. view more (2009-06-16)
UAB Scientists break the hard drive miniaturisation limit
Magnetic memory-based information storage systems are getting smaller and smaller, while their capacities are getting larger. However, there is a limit to how small they can get. If the tiny magnets used to store information are smaller than around five nanometres (millionths of a millimetre), vibrations caused by temperature can erase their... view more... (2003-07-10)
Magnetic nanoparticles navigate therapeutic genes through the body
Health professionals send genes and healthy cells on their way through the bloodstream so that they can, for example, repair tissue damage to arteries. view more (2009-03-05)
Delft research increases understanding of Earth's magnetic field
Research recently conducted at Delft University of Technology marks an important step forward in understanding the origins of the Earth's magnetic field. The research findings are published this week in the scientific journal Physical Review Letters. view more (2007-03-12)
Gene that magnetically labels cells shows potential as imaging tool
Mammalian cells can produce tiny magnetic nuggets after the introduction of a single gene from bacteria, scientists have found. The gene MagA could become a valuable tool for tracking cells' movement through the body via magnetic resonance imaging (MRI), says Xiaoping Hu, PhD, professor of biomedical engineering at Emory University and the Georgia... view more...

Earth's magnetic field really did reverse itself
NWO researchers have developed an improved method of identifying the magnetic signals in old geological strata. The researchers used the new method to show that the earth's magnetic field really did reverse itself ten million years ago. Particles of iron in sediments orient themselves in accordance with the local magnetic field of the earth. As... view more... (2001-11-27)
Magnetic nanoparticles assembled into long chains
Chains of 1 million magnetic nanoparticles have been assembled and disassembled in a solution of suspended particles in a controlled way. view more (2005-10-21)
News from Earth's magnetic field
It is widely known that the geomagnetic field shields our planet against highly energetic cosmic particles. The importance of the magnetic field for answering geological, tectonic or even archaeological questions is less known. view more (2007-12-21)
Surprisingly rapid changes in the Earth's core discovered
In a recent paper published in Nature Geoscience, the geophysicist Mioara MANDEA from the GFZ German Research Centre for Geosciences, Potsdam and her Danish colleague Nils OLSEN from the National Space Institute/DTU Copenhagen, have shown that motions in the fluid in the Earth's core are changing surprisingly fast, and that this, in turn, effects... view more...

Questions over accuracy of MRI in diagnosing multiple sclerosis
The accuracy of magnetic resonance imaging (MRI) is not sufficient to rule in or rule out a diagnosis of MS with a high degree of certainty, finds a study published online by the BMJ today. view more (2006-03-24)
Hydrogen found to transmit magnetism
A team of chemists and physicists at the Universities of Liverpool and Oxford have shown that hydrogen transmits magnetism. This discovery could be the first step to a new class of magnetic materials, and opens up a new field of chemistry. The team, headed by Professor Matthew Rosseinsky of the Department of Chemistry, University of Liverpool, and... view more... (2002-03-07)
New coil to make magnetic resonance (MR) imaging easier
Oxford University researchers have devised a novel coil design for magnetic resonance (MR) application, devised specifically for deep organ MR where sensitive imaging and spectroscopy have been previously difficult. Deep organ magnetic resonance requires maximised sensitivity and magnetic field homogeneity over a relatively large field of view... view more... (2003-01-24)
Tiny magnetic crystals in bacteria are a compass, say Imperial researchers
Scientists have shown that tiny crystals found inside bacteria provide a magnetic compass to help them navigate through sediment to find the best food, in research out today. view more (2008-12-17)
Details of solar particles penetrating the Earth's environment revealed
Co-ordinated efforts by China/ESA's Double Star and ESA's Cluster spacecraft have allowed scientists to zero in on an area where energetic particles from the Sun are blasting their way through the Earth's magnetic shield. view more (2006-10-04)
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)
Magnet Made Of Pure Carbon
All known magnets contain metals and so far scientists believed that non-metallic material could not behave like a strong magnet. However, at the end of 20th century, some organic substances with strong magnetic properties were found, but they were magnetic only at very low temperatures, just above liquid helium. It seemed impossible to obtain... view more... (2001-10-24)
Researchers reveal mystery of bacterial magnetism
Scientists at the Naval Research Laboratory (NRL) and Purdue University have shed light on one of microbiology's most fascinating mysteries-why some bacteria are naturally magnetic. view more (2006-10-23)
3-D imaging -- first insights into magnetic fields
3-D images are not only useful in medicine; the observation of internal structures is also invaluable in many other fields of scientific investigation. view more (2008-03-31)
Einstein's magnetic effect is measured on microscale
A gyromagnetic effect discovered by Albert Einstein and Dutch physicist Wander Johannes de Haas-the rotation of an object caused by a change in magnetization-has been measured at micrometer-scale dimensions for the first time at the National Institute of Standards and Technology (NIST). view more (2006-10-02)
Mars Express discovers aurorae on Mars
ESA's Mars Express spacecraft has for the first time ever detected an aurora on Mars. This aurora is of a type never previously observed in the Solar System. view more (2005-06-10)
