ESA's XMM-Newton makes the first measurement of a dead star's magnetism
Using the superior sensitivity of ESA's X-ray observatory, XMM-Newton, a team of European astronomers has made the first direct measurement of a neutron star's magnetic field. The results provide deep insights into the extreme physics of neutron stars and reveal a new mystery yet to be solved about the end of this star's life. A neutron star is... view more... (2003-06-11)
Glasgow astronomers explain hot star disks
Astronomers have been puzzled for decades as to how the rings of hot gas surrounding certain types of star are formed. Now a team of scientists from the Universities of Glasgow and Wisconsin believe they have found the answer. The team studied a type of young, hot star, known as a "Be star", that has a disk of glowing gas around it, similar to the... view more... (2002-11-01)
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)
New magnetic separation technique might detect multiple pathogens at once
A magnetic separation technique developed by researchers at Duke University's Pratt School of Engineering and Purdue University makes it relatively simple to sort through beads hundreds of times smaller than the period at the end of this sentence. view more (2007-10-30)
Discovery at UAB brings us nearer to making the dream of invisibility true
A group of researchers from the Department of Physics at UAB have designed a device, called a dc metamaterial, which makes objects invisible under certain light - very low frequency electromagnetic waves - by making the inside of the magnetic field zero but not altering the exterior field. view more (2009-07-08)
Young Galaxy's Magnetism Surprises Astronomers
Astronomers have made the first direct measurement of the magnetic field in a young, distant galaxy, and the result is a big surprise. view more (2008-10-02)
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)
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)
Animal magnetism provides a sense of direction
They may not be on most people's list of most attractive species, but bats definitely have animal magnetism. Researchers from the Universities of Leeds and Princeton have discovered that bats use a magnetic substance in their body called magnetite as an 'internal compass' to help them navigate. view more (2008-02-27)
Dissecting a stellar explosion
Integral has captured one of the brightest gamma-ray bursts ever seen. A meticulous analysis of the data has allowed astronomers to investigate the initial phases of this giant stellar explosion, which led to the ejection of matter at velocities close to the speed of light. view more (2009-04-06)
Changing the rings: a key finding for magnetics design
Researchers at the National Institute of Standards and Technology's Center for Nanoscale Science and Technology (CNST) have done the first theoretical determination of the dominant damping mechanism that settles down excited magnetic states-"ringing" in physics parlance-in some key metals. view more (2007-08-06)
The missing link in the evolution of magnetic cataclysmic stars?
An international team of astronomers might have discovered the missing link in the evolution of the so-called magnetic cataclysmic variable stars. They determined the spin and orbital periods of the binary star Paloma. view more (2007-09-17)
Low-cost magnetic field sensors
People who can claim possession of the latest generation of outdoor wristwatch may rightly assume that the conventional compass with its magnetic needle has served its time. Thanks to modern, space-saving chip technology, new features are constantly being integrated: altimeters, cameras, or even electronic compasses can be conveniently worn on the... view more...

Seeing magnetic fields
It has long been known that migratory birds can make use of the earth's magnetic fields to navigate. Birds read the angle that magnetic fields create on the ground and thereby determine how far north or south they are of the magnetic equator and the magnetic pole. But how do they do this? Is there some unknown "magnetic sense"? It seems... view more... (2004-02-23)
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...

New discovery at Jupiter could help protect Earth-orbit satellites
Radio waves accelerate electrons within Jupiter's magnetic field in the same way as they do on Earth, according to new research published in Nature Physics this week. The discovery overturns a theory that has held sway for more than a generation and has important implications for protecting Earth-orbiting satellites. view more (2008-03-10)
The Sun`s Twisted Mysteries
Solar physicists at the Mullard Space Science Laboratory (MSSL, University College London) in Surrey have found new clues to the thirty year old puzzle of why the Sun ejects huge bubbles of electrified gas, laced with magnetic field, known as coronal mass ejections (CMEs). In a paper published this month in the Journal of Solar Physics, they... view more... (2002-08-30)
Another world-record achievement for National High Magnetic Field Laboratory
The National High Magnetic Field Laboratory is ending its year with another achievement of international importance as engineers and technicians this week completed testing of a world-record magnet. view more (2005-12-15)
Pocket-sized magnetic resonance imaging
The term "MRI scan" brings to mind the gigantic, expensive machines that are installed in hospitals. But research scientists have now developed small portable MRI scanners that perform their services in the field: for instance to examine ice cores. view more (2008-07-09)
Mechanical motion used to 'spin' atoms in a gas
For the first time, mechanical motion has been used to make atoms in a gas "spin," scientists at the National Institute of Standards and Technology (NIST) report. view more (2006-12-11)
