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... view more (2001-11-27)

Surprisingly rapid changes in the Earth's core discovered

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... view more (2003-01-24)

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)

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)

Unravelling a cosmic mystery-scientists discover the Universe's strongest magnetic field
Scientists from The University of Exeter and the International University, Bremen have discovered what is thought to be the strongest magnetic field in the Universe.   view more (2006-03-31)

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)

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)

Cluster opens a new window on 'magnetic reconnection' in the near-Earth space
Plasma physicists have made an unprecedented measurement in their study of the Earth's magnetic field. Thanks to ESA's Cluster satellites they detected an electric field thought to be a key element in the process of 'magnetic reconnection'.   view more (2007-03-13)

Improved Spin Transistor from Oxford University
Researchers at Oxford University’s Physics Department have developed an improved version of the “spin transistor,” a device which has the principle operating characteristics of a conventional transistor but with the added benefit of a current output dependent on the strength of... view more (2002-08-15)

Delft University of Technology rotates electron spin with electric field
Researchers at the Delft University of Technology's Kavli Institute of Nanoscience and the Foundation for Fundamental Research on Matter (FOM) have succeeded in controlling the spin of a single electron merely by using electric fields.   view more (2007-11-02)

Astronomers report unprecedented double helix nebula near center of the Milky Way
Astronomers report an unprecedented elongated double helix nebula near the center of our Milky Way galaxy, using observations from NASA's Spitzer Space Telescope.   view more (2006-03-16)

Magnetic computer sensors may help study biomolecules
Magnetic switches like those in computers also might be used to manipulate individual strands of DNA for high-speed applications such as gene sequencing, experiments at the National Institute of Standards and Technology (NIST) suggest.   view more (2007-05-11)

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)

External Magnetic Field Causes The Puzzling Heating Of The Solar Corona
The Russian astrophysicists have theoretically modelled coronal loop oscillations and have shown that the plasma present in coronal loops is quite "normal". So, the puzzle of the Sun`s atmosphere heating remains unresolved.          Coronal loops, immense... view more (2002-06-21)

New magnets with 99% air content
Researchers from the Physics Department at the Universitat Autònoma de Barcelona (UAB), the Institut de Cie'nca de Materials de Barcelona (ICMAB-CSIC), and the Universidad de Zaragoza have created a new ultra-light transparent magnetic material. Thanks to its properties, the new material... view more (2003-11-25)

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... 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... view more (2002-11-01)

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)

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... view more (2002-03-07)
