An about-face on electrical conductivity at the interface

November 15, 2011 3:40 am | News | Comments

To improve the electronic devices that keep our world organized, scientists are on the hunt for new semiconductor materials. One answer could lie with an unusual form of electrical conductivity that takes place at the junction of two oxides. However, a group of scientists were recently surprised to find the interface of two complex oxides—the polar lanthanum chromium oxide, and the nonpolar strontium titanium oxide—did not conduct electricity.

Biosensor benefits from melding of carbon nanotubes, DNA

November 15, 2011 3:16 am | News | Comments

For decades, scientists have dreamed of building computer systems that could replicate the human brain's talent for learning new tasks. Massachusetts Institute of Technology researchers have now taken a major step toward that goal by designing a computer chip that mimics how the brain's neurons adapt in response to new information.

Ancient midges offer clues to climate variability 10,000 years ago

November 14, 2011 10:24 am | News | Comments

An analysis of the remains of ancient midges—tiny non-biting insects closely related to mosquitoes—opens a new window on the past with a detailed view of the surprising regional variability that accompanied climate warming during the early Holocene epoch, 10,000 to 5,500 years ago.


Animals inspire advances in ultrasound technology

November 14, 2011 9:09 am | News | Comments

Sonar and ultrasound, which use sound as a navigational device to paint accurate pictures of an environment, are the basis of countless technologies, including medical ultrasound machines and submarine navigation systems. But when it comes to more accurate sonar and ultrasound, animals' "biosonar" capabilities still have the human race beat. Until now.
