Scientists build world’s first anti-laser

February 18, 2011 3:36 am | News | Comments

More than 50 years after the invention of the laser, scientists at Yale Univ. have built the world's first anti-laser, in which incoming beams of light interfere with one another in such a way as to perfectly cancel each other out. The discovery could pave the way for a number of novel technologies with applications in everything from optical computing to radiology.

Want robust robots? Let them be babies first

January 20, 2011 9:09 am | News | Comments

Want to build a really tough robot? Forget about Terminator . Instead, watch a tadpole turn into a frog. Or at least that’s not too far off from what Univ. of Vermont roboticist Josh Bongard has discovered . In a first-of-its-kind experiment, Bongard created both simulated and actual robots that, like tadpoles becoming frogs, change their body forms while learning how to walk. And, over generations, his simulated robots also evolved, spending less time in “infant” tadpole-like forms and more time in “adult” four-legged forms.

Free electron laser hits milestone

January 20, 2011 4:45 am | News | Comments

Reactor paves the way for efficiently producing fuel from sunlight

January 19, 2011 3:57 am | News | Comments

Using a common metal most famously found in self-cleaning ovens, Sossina Haile hopes to change our energy future. The metal is cerium oxide—or ceria—and it is the centerpiece of a promising new technology developed by Haile and her colleagues that concentrates solar energy and uses it to efficiently convert carbon dioxide and water into fuels.


Toyota developing alternative electric motor

January 16, 2011 9:40 pm | by The Associated Press | News | Comments

The maker of the popular Prius hybrid car is developing a new type of electric motor to cut its dependence on rare earth metals and lower costs. The world’s No. 1 automaker hopes the new technology will free it from reliance on China, which produces 97% of the global output of rare earths.

Method discovered to determine when metals reach end of life

January 14, 2011 3:42 am | News | Comments

We live in a world almost completely dependent upon machinery. Since the creation of the simple wheel, humans have found ways to increase quality of life and advance scientific knowledge using these devices. Though the prevalence of machinery has benefited us, our dependence upon them has limitations. Everything that moves can and will break, especially metals under strain. And when they fail, the consequences can be catastrophic. LSU's Michael Khonsari has developed and proven a novel method to avoid the danger that comes with reaching the breaking point.

Nano-laser developed for medicine and electronics

January 13, 2011 4:28 am | News | Comments

Lasers have revolutionized the communications and medical industries. However, the physical length of an ordinary laser cannot be less than one half of the wavelength of its light, which limits its application in many industries. Now the Spaser, a new invention developed in part by Tel Aviv Univ., can be as small as needed to fuel nano-technologies of the future.
