Eco friendly magnetic fridges and AC’s come step closer to reality

October 3rd, 2009 WASHINGTON - Scientists have put a certain controversy to rest, by ascertaining that in ancient times, the Earth's magnetic field was structured like the two-pole model of today, which suggests that the methods geoscientists use to reconstruct the geography of early land masses on the globe are accurate. The findings may lead to a better understanding of historical continental movement, which relates to changes in climate.

September 17th, 2009 WASHINGTON - In a new study, scientists have found that auroral bright spots on the planet Jupiter are caused by the magnetosphere of its innermost moon - Ganymede. As Ganymede and Io orbit Jupiter, they interact with regions of plasma and generate electromagnetic waves that are projected along Jupiter's magnetic field lines towards Jupiter's poles where they cause auroral bright spots.

September 16th, 2009 WASHINGTON - Scientists have come closer to engineering drug-free cannabis plant after identifying genes that produce psychoactive substance in marijuana. University of Minnesota researchers have identified genes producing tetrahydrocannabinol (THC), the psychoactive substance in marijuana, which could lead to new and better drugs for pain, nausea and other conditions.

September 4th, 2009 WASHINGTON - In a new research, a team of scientists has for the first time observed magnetic monopoles and how they emerge in a real material. The research was done by scientists from the Helmholtz-Zentrum Berlin fur Materialien und Energie, Germany, in cooperation with colleagues from Dresden, St.

July 8th, 2009 WASHINGTON - A team of researchers at the Universitat Autonoma de Barcelona (UAB) have come up with a device called a dc metamaterial, which makes objects invisible under certain light. The device does so, according to the researchers, under very low frequency electromagnetic waves by making the inside of the magnetic field zero, but not altering the exterior field.

July 4th, 2009 WASHINGTON - Scientists have performed numerical calculations that show how convective mixing flows in the Earth's liquid outer core can cause the geomagnetic dipole to collapse. For the past 160 years, the Earth's magnetic dipole has been weakening at a rate of nearly six percent per century.

June 17th, 2009 WASHINGTON - Scientists have created a new fabricated material that changes color instantly in response to external magnetic field, which could pave the way for manufacturing rewritable color display units and environmentally friendly color paints. A research team, led by a chemist at the University of California, Riverside, created the material.

June 16th, 2009 WASHINGTON - Scientists have discovered a 'magnetic superatom', which one day may be used to create molecular electronic devices for the next generation of faster computers with larger memory storage. Found by a team of Virginia Commonwealth University (VCU) scientists, the 'magnetic superatom' is a stable cluster of atoms that can mimic different elements of the periodic table.

June 15th, 2009 WASHINGTON - A new research by scientists in the US has linked variations in the Earth's magnetic field with the ebb and flow of the world's oceans. The origin and mechanism of the Earth's magnetic field are amongst the biggest unsolved questions in the earth sciences.

May 29th, 2009 WASHINGTON - The world's largest solar telescope, which can capture the Sun's magnetic field better than other telescopes, is now operational. The new 1.6-meter clear aperture solar telescope, the largest of its kind in the world, is housed at the New Jersey Institute of Technology in Newark, New Jersey, US.

May 29th, 2009 WASHINGTON - Using data from NASA's THEMIS mission, a team of University of Alberta researchers has pinpointed the impact epicenter of an earthbound space storm as it crashes into the atmosphere, and given an advance warning of its arrival. The team's study reveals that magnetic blast waves can be used to pinpoint and predict the location where space storms dissipate their massive amounts of energy.

May 28th, 2009 WASHINGTON - Scientists are working on infinitesimally small rotors that may one day lead to nano-scale generators. Collaborating with the Chinese Academy of Sciences in Beijing, a research team have already probed the rotation of molecules on a fixed surface to understand how they may help in the development of future rotor-based machinery at nanoscale level.he researchers focussed on rotating magnetic fields, which play an important part in machines like electric motors and generators.

May 22nd, 2009 WASHINGTON - A new research has led to the discovery of miniscule magnets in ant antennae, which act as an internal GPS (Global positioning system), making these insects aware as to where they are going. According to a report in Discovery News, while human global positioning systems rely upon receivers that pick up information from a network of satellites, the probable ant system weighs next to nothing, requires little energy to operate and appears to be mostly built out of dirt.

May 12th, 2009 WASHINGTON - In a new research, scientists suggest that a "supergiant" asteroid several times larger than the one that likely killed the dinosaurs struck Mars with such force that it shut down the planet's magnetic field. Based on the number of large craters present, scientists think very early Mars suffered 15 or so giant impacts within a span of about a hundred million years.

March 12th, 2009 WASHINGTON - An International team of physicists has been able to prove the existence of a "spin battery", a battery that is "charged" by applying a large magnetic field to nano-magnets in a device called a magnetic tunnel junction (MTJ). Developed by researchers at the University of Miami and at the Universities of Tokyo and Tohoku, in Japan, the new technology is a step towards the creation of computer hard drives with no moving parts, which would be much faster, less expensive and use less energy than current ones.
