1. Enceladus geysers mask the length of Saturn's day
   03-22-2007 · European Space Agency (ESA)
   In a David and Goliath story of Saturnian proportions, the little moon Enceladus is weighing down giant Saturn's magnetic field so much that the field is rotating slower than the planet. This phenomenon makes it nearly impossible to measure the length of the Saturn day using techniques that work at the other giant planets.

2. Do migratory birds 'see' the magnetic field?
   09-25-2007 · EurekAlert!
   Every year millions of migratory birds fly towards their wintering quarters and come back in next year's spring to breed. Behavioral experiments have shown that the Earth's magnetic field is the main orientation cue on their journeys. Nevertheless, surprisingly little is known about the neuronal substrates underlying these navigational abilities.

3. Astronomers find puzzling dwarf star with complex magnetic fields
   12-05-2007 · EurekAlert!
   Typically, little M-dwarf stars -- the most common type of star in the galaxy -- are cold, quiet, and dim. Now a team of astronomers led by Edo Berger, a Carnegie-Princeton postdoctoral fellow, found one M-dwarf that doesn't conform. It has an unusually active and complex magnetic field, stronger than our own Sun's, and a huge hot spot that covers half of its surface.

4. New theory explains enhanced superconductivity in nanowires
   10-18-2006 · EurekAlert!
   Superconducting wires are used in magnetic resonance imaging machines. Eventually, ultra-narrow superconducting wires might be used in power lines designed to carry electrical energy long distances with little loss. Now, researchers at the University of Illinois at Urbana-Champaign not only have discovered an unusual phenomenon in which ultra-narrow wires show enhanced superconductivity when exposed to strong magnetic fields, they also have developed a theory to explain it.

5. Chickens also orient themselves by the Earth's magnetic field
   07-05-2007 · EurekAlert!
   Until recently, people believed that the ability to orient themselves by the Earth's magnetic field was restricted to migratory birds. Now ornithologists at Frankfurt University have discovered that domestic chickens also have a built-in compass. It is clear that a magnetic sense of direction developed at an early stage of evolution. The Earth's magnetic field was presumably used by the ancestors of today's birds as an aid to finding their way about their environment.

6. Nano-layer of ruthenium stabilizes magnetic sensors
   08-03-2007 · EurekAlert!
   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 NIST show. The nonmagnetic metal acts as a buffer between active layers of sensor materials, offering a simple means of customizing field instruments such as compasses and stabilizing the magnetization in a given direction in devices such as computer hard-disk readers.

7. Return to Europa: A closer look is possible
   12-13-2007 · EurekAlert!
   New research brings scientists closer to exploring the ice-covered ocean of Europa, one of Jupiter's moons. New methods in measuring gravity and magnetic fields, new radar sounding techniques, new technology being field tested in Antarctica, and findings of lower radiation levels and the presence of carbon dioxide (a key ingredient for life) on Europa make the moon a tantalizing prospect for exploration, as scientists explain at the 2007 meeting of the American Geophysical Union.

10. Researchers identify driver for near-Earth space weather
    12-11-2006 · EurekAlert!
    New findings indicate that the aurora and other near-Earth space weather are driven by the rate at which the Earth's and sun's magnetic fields connect, or merge, and not by the solar wind's electric field as was previously assumed.
