'Microring' device could aid in future optical technologies Posted: 19 Oct 2011 11:52 PM PDT Researchers have created a device small enough to fit on a computer chip that converts continuous laser light into numerous ultrashort pulses, a technology that might have applications in more advanced sensors, communications systems and laboratory instruments.

Magnetic attraction: Microchip demonstrates concept of 'MRAM for biomolecules' Posted: 19 Oct 2011 06:28 PM PDT Researchers have developed a low-power microchip that uses a combination of microfluidics and magnetic switches to trap and transport magnetic beads. The novel transport chip may have applications in biotechnology and medical diagnostics.

Using new technique, scientists uncover a delicate magnetic balance for superconductivity Posted: 19 Oct 2011 02:43 PM PDT A new imaging technology is giving scientists unprecedented views of the processes that affect the flow of electrons through materials. By modifying a familiar tool in nanoscience -- the scanning tunneling microscope -- researchers have been able to visualize what happens when they change the electronic structure of a "heavy fermion" compound made of uranium, ruthenium and silicon. What they found sheds light on superconductivity -- the movement of electrons without resistance -- which typically occurs at extremely low temperatures and that researchers hope one day to achieve at something close to room temperature, which would revolutionize electronics.

Spiral arms hint at presence of planets: High resolution image of young star with circumstellar disks verifies predictions Posted: 19 Oct 2011 02:02 PM PDT A new image of the disk of gas and dust around a sun-like star has spiral-arm-like structures. These features may provide clues to the presence of embedded but as-yet-unseen planets.

Planet-sized object as cool as Earth revealed in record-breaking photo Posted: 19 Oct 2011 01:52 PM PDT Scientists are presenting the photo of a nearby star and its orbiting companion -- whose temperature is like a hot summer day in Arizona. The planet-like companion is the coldest object ever directly photographed outside our solar system, researchers say.

Key property of potential 'spintronic' material measured Posted: 19 Oct 2011 01:45 PM PDT An advanced material that could help bring about next-generation "spintronic" computers has revealed one of its fundamental secrets to a team of scientists.

Orion's Belt lights up Cassini's view of Enceladus Posted: 19 Oct 2011 01:21 PM PDT NASA's Cassini mission will take advantage of the position of two of the three stars in Orion's belt when the spacecraft flies by Saturn's moon Enceladus on Oct. 19. As the hot, bright stars pass behind the moon's icy jets, Cassini's ultraviolet imaging spectrograph will acquire a two-dimensional view of these dramatic plumes of water vapor and icy material erupting from the moon's southern polar region. This flyby is the mission's first-ever opportunity to probe the jets with two stars simultaneously, a dual stellar occultation.

NASA's Spitzer detects comet storm in nearby solar system Posted: 19 Oct 2011 01:19 PM PDT NASA's Spitzer Space Telescope has detected signs of icy bodies raining down in an alien solar system. The downpour resembles our own solar system several billion years ago during a period known as the "Late Heavy Bombardment," which may have brought water and other life-forming ingredients to Earth.

What makes tires grip the road on a rainy day? Posted: 19 Oct 2011 12:45 PM PDT Scientists have recently developed a model to predict the friction occurring when a rough surface in wet conditions (such as a road on a rainy day) is in sliding contact with a rubber material (such as a car tire tread block).

World record in 3-D imaging of porous rocks: Stack of 35 million megapixel-photos Posted: 19 Oct 2011 07:55 AM PDT Physicists have established a world record in the field of three-dimensional imaging of porous materials. The scientists have generated the largest and most precise three-dimensional image of the pore structure of sandstone. The image was generated within a project of the Simulation Technology Cluster of Excellence, and contains more than 35 trillion (a number with thirteen digits) voxels.

Glowing beacons reveal hidden order in dynamical systems: Experimental confirmation of a fundamental physical theorem Posted: 19 Oct 2011 07:49 AM PDT A dynamical system in which repeated measurements on a single particle yield the same mean result as a single measurement of the whole ensemble is said to be ergodic. The ergodic theorem expresses a fundamental physical principle, and its validity for diffusive processes has now been demonstrated.

Internet security: Researchers break W3C standard Posted: 19 Oct 2011 07:49 AM PDT Standards are supposed to guarantee security, especially in the WWW. The World Wide Web Consortium (W3C) is the main force behind standards like HTML, XML, and XML Encryption. But implementing a W3C standard does not mean that a system is secure. Researchers from the chair of network and data security have found a serious attack against XML Encryption. "Everything is insecure", is the uncomfortable message from the researchers.
