Optical microscopes are limited by a phenomenon known as the diffraction barrier, wherein the microscope can’t differentiate two objects separated by less than half the wavelength of light used—roughly 200 nm on average for the visible spectrum. But by combining powerful optics and cutting-edge rendering algorithms, GE’s new DeltaVision OMX Blaze is bringing this hidden realm’s drama to light. More »
Google releases Course Builder, takes online learning down an open-source road
Posted in: Today's ChiliGoogle 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.

You, sir or ma’am, should probably not get too excited. Chances are, this trans-Pacific 10 Gigabit link won’t do you any good, personally. On the other hand, researchers working together across the oceanic divide have tons to cheer about. The China Education and Research Network, the National Science Foundation and Indiana University worked together with BGI, one of the largest genomics organizations in the world, to christen the connection by transferring 24 Gigabytes of genomic data from Beijing to UC Davis in under 30 seconds. As a benchmark, the same file was sent between the same locations over the regular ol’ Internet and it took over 26 hours. The high-speed link should prove to be a major boon for genetic research and DNA sequencing.
