Computing the best high-resolution 3-D tissue images

Posted: 23 Apr 2012 03:42 PM PDT

Real-time, 3-D microscopic tissue imaging could be a revolution for medical fields such as cancer diagnosis, minimally invasive surgery and ophthalmology. Researchers have developed a technique to computationally correct for aberrations in optical tomography, bringing the future of medical imaging into focus. The computational technique could provide faster, less expensive and higher-resolution tissue imaging to a broader population of users.

Scientists see solution to critical barrier to fusion

Posted: 23 Apr 2012 11:31 AM PDT

Physicists have discovered a possible solution to a mystery that has long baffled researchers working to harness fusion. If confirmed by experiment, the finding could help scientists eliminate a major impediment to the development of fusion as a clean and abundant source of energy for producing electric power.

Astrobiologist proposes fleet of probes to seek life on Mars: Sensors would punch into soil, run range of tests

Posted: 23 Apr 2012 11:31 AM PDT

Astrobiologists are calling for a mission to Mars with "a strong and comprehensive life detection component." At the heart of their proposal is a small fleet of sensor packages that can punch into the Martian soil and run a range of tests for signs of ancient or existing life.

Medical 'lightsabers': Laser scalpels get ultrafast, ultra-accurate, and ultra-compact makeover

Posted: 23 Apr 2012 10:18 AM PDT

Researchers have developed a small, flexible endoscopic medical device fitted with a femtosecond laser "scalpel" that can remove diseased or damaged tissue while leaving healthy cells untouched.

Unique research on inner life of Google

Posted: 23 Apr 2012 10:18 AM PDT

Google is one of the world's most innovative companies. A Swedish researcher has been seeking answers inside the company's headquarters Googleplex for nearly a year. No other researcher has ever had such access. The study is based on in-depth interviews with 28 employees. Among other things, they were asked to rank various possible explanations for Google's success in constantly developing new services that people want to use.

Making human textiles: Research team ups the ante with development of blood vessels woven from donor cells

Posted: 23 Apr 2012 10:15 AM PDT

A lot of people were skeptical when two young California-based researchers set out more than a decade ago to create a completely human-derived alternative to the synthetic blood vessels commonly used in dialysis patients. Since then, they've done that and more.

Biometrics: Those tell-tale signs that say who you are

Posted: 23 Apr 2012 07:47 AM PDT

Forget about fingerprints or iris recognition; the way you walk or move your hands, even your pulse, can be analyzed for unique characteristics. Researchers are now looking at ways this new technology could protect your security and make identity checking less obtrusive and more accurate.

Compressed sensing allows imaging of live cell structures

Posted: 23 Apr 2012 07:40 AM PDT

Researchers have advanced the ability to view a clear picture of a single cellular structure in motion. By identifying molecules using compressed sensing, this new method provides needed spatial resolution plus a faster temporal resolution.

New technique may help severely damaged nerves regrow and restore function

Posted: 22 Apr 2012 08:24 PM PDT

Engineers have developed a method of assisting nerves damaged by traumatic accidents to repair naturally, which could improve the chances of restoring sensation and movement in injured limbs.

Controlling heat flow with atomic-level precision

Posted: 22 Apr 2012 10:49 AM PDT

Through a combination of atomic-scale materials design and ultrafast measurements, researchers have revealed new insights about how heat flows across an interface between two materials. The researchers demonstrated that a single layer of atoms can disrupt or enhance heat flow across an interface, a finding with implications for future technologies and for materials research.

Inequality and investment bubbles: A clearer link is established

Posted: 19 Apr 2012 12:39 PM PDT

An expert on statistical mechanics shows that the income distributions for the richest 3 percent and the poorer 97 percent conform to different physics principles.
