Baby's life saved with groundbreaking 3-D printed device that restored his breathing

Posted: 22 May 2013 03:01 PM PDT

A bioresorbable splint has been created and used for first time at the University of Michigan, where doctors implanted the device in an infant and stopped a life-threatening condition called tracheobronchomalacia.

Tests lead to doubling of fuel cell life

Posted: 22 May 2013 01:03 PM PDT

Researchers working to improve durability in fuel cell powered buses have discovered links between electrode degradation processes and bus membrane durability. The team is quantifying the effects of electrode degradation stressors in the operating cycle of the bus on the membrane lifetime.

Magnetic field misbehavior in solar flares explained: The culprit is turbulence

Posted: 22 May 2013 01:03 PM PDT

When a solar flare erupts from the sun, its magnetic fields sometime break a widely accepted rule of physics. Why? Now we know.

Innovation could bring flexible solar cells, transistors, displays

Posted: 22 May 2013 11:20 AM PDT

Researchers have created a new type of transparent electrode that might find uses in solar cells, flexible displays for computers and consumer electronics and future "optoelectronic" circuits for sensors and information processing.

Forecast for Saturn's moon Titan: Wild weather could be ahead

Posted: 22 May 2013 10:32 AM PDT

Saturn's moon Titan might be in for some wild weather as it heads into its spring and summer, if two new models are correct. Scientists think that as the seasons change in Titan's northern hemisphere, waves could ripple across the moon's hydrocarbon seas, and hurricanes could begin to swirl over these areas, too. The model predicting waves tries to explain data from the moon obtained so far by NASA's Cassini spacecraft. Both models help mission team members plan when and where to look for unusual atmospheric disturbances as Titan summer approaches.

Detecting mirror molecules: New technique reliably tells left-handed from right-handed variant of a compound

Posted: 22 May 2013 10:12 AM PDT

Physicists have developed a novel technique that can detect molecular variants in chemical mixtures -- greatly simplifying a process that is one of the most important, though time-consuming, processes in analytical chemistry.

Making chaos visible: As chaos celebrates its 50th birthday, biophysicist Christian Herbst develops a new method to visualize it

Posted: 22 May 2013 10:12 AM PDT

Exactly 50 years after the US-American meteorologist Edward Lorenz discovered chaos (remember the "butterfly effect?") the topic is still as fascinating as ever. A new visualization technique helps to make chaos visible to the naked eye. The method allows for the intuitive interpretation of chaotic or nearly chaotic phenomena, and thus makes the fascinating world of chaos theory more accessible to the scientific community.

Fragile mega-galaxy is missing link in history of cosmos

Posted: 22 May 2013 10:11 AM PDT

Two hungry young galaxies that collided 11 billion years ago are rapidly forming a massive galaxy about 10 times the size of the Milky Way, according to new research.

Model of Sun's magnetic field created

Posted: 22 May 2013 10:11 AM PDT

Researchers have uncovered an important mechanism behind the generation of astrophysical magnetic fields such as that of the Sun.

Plasmonics: A wave without diffraction

Posted: 22 May 2013 10:10 AM PDT

Optical computing could benefit from the recent development of a novel electromagnetic wave.

Optics: Statistics light the way

Posted: 22 May 2013 10:10 AM PDT

A revelation of how photoreceptive cells in the eye distinguish between different light sources could pave the way for a novel class of optical devices.

New technique may open up an era of atomic-scale semiconductor devices

Posted: 22 May 2013 08:20 AM PDT

Researchers have developed a new technique for creating high-quality semiconductor thin films at the atomic scale -- meaning the films are only one atom thick. The technique can be used to create these thin films on a large scale, sufficient to coat wafers that are two inches wide, or larger.

Whirlpools on the nanoscale could multiply magnetic memory

Posted: 22 May 2013 06:58 AM PDT

Scientists are developing four-bit magnetic cells instead of the two-bit magnetic domains of standard magnetic memories. Magnetic vortices are whirlpools of magnetic field, in which electron spins point either clockwise or counterclockwise. In the crowded center of the whirlpool the spins point either down or up. These four orientations could represent separate bits of information in a new kind of memory, if controlled independently and simultaneously.

Polymer breakthrough inspired by trees and ancient celtic knots

Posted: 22 May 2013 05:53 AM PDT

A new slow-motion method of controlling the synthesis of polymers, which takes inspiration from both trees and Celtic knots, opens up new possibilities in areas including medical devices, drug delivery, elastics and adhesives.

Unique method creates correct mirror image of molecule

Posted: 22 May 2013 05:52 AM PDT

Many molecules have a right and a left form, just like shoes. In pharmaceuticals, it is important that the correct form of the molecule is used. Researchers have been able to produce the one mirror image by using crystals with special properties. This can have a major impact on the production of pharmaceuticals.

Big Data, for better or worse: 90% of world's data generated over last two years

Posted: 22 May 2013 05:52 AM PDT

A full 90 percent of all the data in the world has been generated over the last two years. Internet-based companies are awash with data that can be grouped and utilized. Is this a good thing?
