Scientists from Queen Mary, University of London have improved their understanding of the inner workings of our computers and MP3 players, thanks to an exciting new field of research called `organic spintronics`.
Dr Alan Drew from Queen Mary`s Department of Physics and the University of Freiburg, Switzerland, along with colleagues from the Paul Scherrer Institute (PSI), [...]

Investigation of the fireball that lit up the skies of Alberta and Saskatchewan on November 20 has determined that an asteroid fragment weighing approximately 10 tonnes entered the Earth`s atmosphere over the prairie provinces last Thursday evening. And University of Calgary researcher Alan Hildebrand has outlined a region in western Saskatchewan where chunks of [...]

Airtight containers are not always so airtight. As any child will discover the day after a birthday party, even a tightly tied helium balloon will leak its gas out over the course of many hours. Now scientists have come up with a supremely efficient barrier that lets nothing in or out.
As described in a recent [...]

Scientists have made a new theoretical advance in atomic behavior that could lead to sharper magnetic resonance imaging (MRI) pictures. The discovery could one day help enable the development of portable MRI machines.
In the November 25 online issue of the Journal of Chemical Physics, they explain why scientists couldn`t completely control the behavior of atomic nuclei during [...]

Research into the development of invisibility devices has spurred two physicists` thought on the behaviour of light to overcome the seemingly intractable problem of optical singularities which could soon lead to the manufacturing of a perfect cat`s eye.
A research paper published in a New Journal of Physics` focus issue `Cloaking and Transformation Optics` called `The [...]

Jupiter has a rocky core that is more than twice as large as previously thought, according to computer calculations by a University of California, Berkeley, geophysicist who simulated conditions inside the planet on the scale of individual hydrogen and helium atoms.
The simulation predict the properties of hydrogen-helium mixtures at the extreme pressures and temperatures that [...]

NASA`s Dawn spacecraft shut down its ion propulsion system this week as scheduled. The spacecraft is now gliding toward a Mars flyby in February of next year.
"Dawn has completed the thrusting it needs to use Mars for a gravity assist to help get us to Vesta," said Marc Rayman, Dawn`s chief [...]

A new picture of the early Earth is emerging, including the surprising finding that plate tectonics may have started more than 4 billion years ago — much earlier than scientists had believed, according to new research by UCLA geochemists reported Nov. 27 in the journal Nature.
"We are proposing that there was plate-tectonic activity in the [...]

A nontoxic nanoparticle developed by Penn State researchers is proving to be an all-around effective delivery system for both therapeutic drugs and the fluorescent dyes that can track their delivery.
In a recent online issue of Nano Letters, an interdisciplinary group of materials scientists, chemists, bioengineers, physicists, and pharmacologists show that calcium phosphate particles ranging in [...]

Scientists have identified a promising set of new compounds in the fight against muscular dystrophy.
Using a drug-discovery technique in which molecules compete against each other for access to the target – the strand of toxic RNA that causes the most common form of muscular dystrophy in adults – a team at the University of Rochester [...]
