VRSim Debuts SimSpray Augmented Reality Spray Painting Training System (Education)
Posted by: Site Administration
SimSpray is a training appliance created to augment traditional spray coating skills training. Designed to simulate the painting process, the student selects a work piece, paint color, and air pressure settings on the touch screen monitor. The user dons a custom helmet that shows a three dimensional virtual rendering of the work piece in an augmented reality environment. With a modified high-volume/low-pressure (HVLP) spray gun in hand, the user can adjust the spray pattern, trigger the gun, and begin to apply the first coat of virtual paint.

Prion Leaves Lasting Mark on Memory (The Brain)
Posted by: Site Administration
Prions are a special class of proteins best known as the source for mad cow and other neurodegenerative diseases. Despite this negative reputation, according to a new report in the February 5th issue of the journal Cell, a Cell Press publication, a prion may also have important and very positive roles in brain function. The researchers suggest that a prion-like protein may participate in memory in higher eukaryotes, from sea slugs on up.

Code Defends Against 'Stealthy' Computer Worms (Artificial Intelligence)
Posted by: Site Administration
Self-propagating worms are malicious computer programs, which, after being released, can spread throughout networks without human control, stealing or erasing hard drive data, interfering with pre-installed programs and slowing, even crashing, home and work computers. Now a new code, or algorithm, created by Penn State researchers targets the "stealthiest" of these worms, containing them before an outbreak can occur.

First germanium laser brings us closer to 'optical computers' (Computing Power)
Posted by: Site Administration
MIT researchers have demonstrated the first laser built from germanium that can produce wavelengths of light useful for optical communication. It’s also the first germanium laser to operate at room temperature. Unlike the materials typically used in lasers, germanium is easy to incorporate into existing processes for manufacturing silicon chips. So the result could prove an important step toward computers that move data -- and maybe even perform calculations -- using light instead of electricity. But more fundamentally, the researchers have shown that, contrary to prior belief, a class of materials called indirect-band-gap semiconductors can yield practical lasers.

Making Quantum Behavior Observable Using Optical Levitation (Computing Power)
Posted by: Site Administration
Perhaps one of the biggest challenges of modern physics is figuring out how to realize and take advantage of strange quantum behaviors in progressively larger and more complex systems. Progress along this front is expected to shed insight into the nature of quantum mechanics and lead to many novel applications. With this goal in mind, scientists have recently proposed a unique approach that involves optically levitating a nano-mechanical system in order to cool it to its quantum ground state, where the amount of motion of the system reaches the fundamental minimum set by intrinsic quantum fluctuations.

Artificial magnetic fields for light could illuminate correlated quantum systems (Computing Power)
Posted by: Site Administration
In general, the field of many-body physics involves the interactions and collective behavior of large numbers of particles. Scientists have made significant progress in exploring this field, which has led to applications in condensed matter physics, nuclear physics, and astrophysics. However, one challenging area that remains is understanding many-body systems on the quantum level.
