Underwater microscope offers a brand new look at sea life

Scientists have a hard time studying microscope sea life, and for good reason. Underwater scientific equipment can't study things at that scale, and bringing samples up to the surface frequently deprives them of that all-important natural context. En...

Smart car algorithm sees pedestrians as well as you can

It's one thing for computers to spot people in relatively tame academic situations, but it's another when they're on the road -- you need your car to spot that jaywalker in time to avoid a collision. Thankfully, UC San Diego researchers have made tha...

Telescopic contact lenses magnify sight 2.8 times, turn wearer into cyborg

DNP These telescopic contact lenses

Interested in upgrading your eyeballs? Well, a team of DARPA-funded researchers led by Joseph Ford of UC San Diego recently published a proposal for a new type of telescopic contact lens in Optics Express. Designed for people with age-related macular degeneration, the lenses are only 1.17mm thick and can magnify images up to 2.8 times. Their layered construction admits light near the outer edge of the lens, bouncing it across a series of tiny aluminum mirrors before transmitting it to the back of the retina, kind of like the origami-optics lens. Telescopic sight can be toggled on and off by using a pair of 3D glasses to switch the polarization of the central part of the lens. It sounds promising, but the lenses -- pictured after the break -- currently have some obstacles, like gas-impermeable materials unsuitable for long-term wear and sub-par image quality.

Google releases Course Builder, takes online learning down an open-source road

Google releases Course Builder, takes online learning down an opensource road

Google is well-known for projects with unexpected origins. It's almost natural, then, that the code Google used to build a web course has led to a full-fledged tool for online education. The open-source Course Builder project lets anyone make their own learning resources, complete with scheduled activities and lessons, if they've got some skill with HTML and JavaScript. There's also an avenue for live teaching or office hours: the obligatory Google+ tie-in lets educators announce Hangouts on Air sessions. Code is available immediately, although you won't need to be grading virtual papers to see the benefit. A handful of schools that include Stanford, UC San Diego and Indiana University are at least exploring the use of Course Builder in their own initiatives, which could lead to more elegant internet learning -- if also fewer excuses for slacking.

Physicist uses math to get out of a traffic ticket, publishes findings

When most folks get ticketed for running a stop sign, most people wind up writing the court a check. UC San Diego physicist Dmitri Krioukov wrote a mathematical paper instead. Rather than throw his fallible human opinion on the mercy of the court, Krioukov uses a series of equations and graphs to prove that the accusing officer confused his car's real space-time trajectory "for a trajectory of a hypothetical object moving at approximately constant linear speed without stopping at the stop sign." In other words, the officer was wrong, but Krioukov stresses that it isn't the officer's fault. "This mistake is fully justified," he writes, pointing to the math. "As a result of this unfortunate coincidence, the O's perception of reality did not properly reflect reality." And to think, you probably never thought you'd use this kind of math in the real world.
