Projecting a robot’s intentions

October 29, 2014 1:27 pm | by Jennifer Chu, MIT | Videos | Comments

Inside Massachusetts Institute of Technology’s Building 41, a small, Roomba-like robot is trying to decided where to go. As the robot considers its options, its “thoughts” are projected on the ground in the form of different colored dots and lines. This new visualization system, called “measurable virtual reality”, combines projectors with motion-capture technology and animation software to project a robot’s intentions in real time.

Physicists find simple solution for quantum technology challenge

October 28, 2014 12:53 pm | News | Comments

Quantum technology devices, such as high-precision sensors and specialised superfast computers, often depend on harnessing the delicate interaction of atoms. However, the methods for trapping these tiny particles are hugely problematic because of the atoms’ tendency to interact with their immediate environment. Scientists in the U.K. have recently shown how to make a new type of flexibly designed microscopic trap for atoms.

Dazzlingly sharp images on curved screens

October 27, 2014 12:54 pm | News | Comments

Projecting images on curved screens poses a dilemma. The sharper the image, the darker it is, even when using lasers and scanning mirrors. A novel optical approach involving the use of an array of microprojectors now brings brightness and sharpness together for the first time on screens of any curvature. It also allows an increase in projection rates by about 10,000 times.

NASA identifies ice cloud above cruising altitude on Titan

October 27, 2014 9:34 am | News | Comments

Scientists have identified an unexpected high-altitude methane ice cloud on Saturn's moon Titan that is similar to exotic clouds found far above Earth's poles. Now, eight years after spotting this mysterious bit of atmospheric fluff, NASA's Cassini spacecraft, researchers have determined that it contains methane ice, which produces a much denser cloud than the ethane ice previously identified there.

How to pick a college? Data crunchers hope to help

October 27, 2014 7:54 am | by Anne Flaherty, Associated Press | News | Comments

For many high school seniors, fall means deciding where to apply for college and maybe visiting a guidance counselor. Data crunchers hope to help. The popularity of social media sites and advancements in the ability to analyze the vast amounts of data we put online give members of the class of 2015 more tools than ever to help chart their next step, even if finding the right college is an inexact science.

Turning loss to gain

October 27, 2014 7:42 am | by Steven Schultz, Princeton Univ. | News | Comments

Lasers are so deeply integrated into modern technology that their basic operations would seem well understood. CD players, medical diagnostics and military surveillance all depend on lasers. Re-examining longstanding beliefs about the physics of these devices, Princeton Univ. engineers have now shown that carefully restricting the delivery of power to certain areas within a laser could boost its output by many orders of magnitude.
