Researchers develop new method of controlling nanodevices

February 25, 2013 9:46 am | by Bill Kisliuk, UCLA | News | Comments

By using electric voltage instead of a flowing electric current, researchers from the University of California, Los Angeles have made major improvements to an ultrafast, high-capacity class of computer memory known as magnetoresistive random access memory, or MRAM. The team's improved memory, which they call MeRAM for magnetoelectric random access memory, has great potential to be used in future memory chips for almost all electronic applications.  

Got food allergies? Test your meal on the spot

December 14, 2012 9:48 am | News | Comments

Are you allergic to peanuts and worried there might be some in that cookie? Now you can find out using a rather unlikely source: your cell phone. A team of researchers from the University of California, Los Angeles has developed a lightweight device called the iTube, which attaches to a common cell phone to detect allergens in food samples.

Comet collisions every six seconds explain 17-year-old stellar mystery

November 9, 2012 1:04 pm | News | Comments

Every six seconds, for millions of years, comets have been colliding with one another near a star in the constellation Cetus called 49 CETI, which is visible to the naked eye. Over the past three decades, astronomers have discovered hundreds of dusty disks around stars, but only two—49 CETI is one—have been found that also have large amounts of gas orbiting them. Until now, the answer was unclear as to why.

Researchers develop novel 'stamping' process to pattern biomolecules

September 21, 2012 4:05 am | News | Comments

Fabricating precise biomolecular structures at extremely small scales is critical to the progress of nanotechnology. Traditionally this has been accomplished through the use of rubber stamps with tiny features which are covered with molecular inks and then stamped onto substrate surfaces, creating molecular patterns. However, when using this technique at the nanoscale, molecules tend to diffuse on the surface both during and after stamping, blurring the patterns. Now, a team of researchers have turned this "soft lithography" process on its head.
