Optical Cables, from Thin Air!
by Gabriel in Lunatic Laboratories
It’s a project that would make Tesla proud. Just imagine being able to instantaneously run an optical cable or fiber to any point on earth, or even into space. That’s what researchers are trying to do. Did I mention it was instantaneous and involved no connection other than the air around us? Well if you are as excited as I am, then you should read on! If not, two words, laser weapons!!... Read more »

Haha, kkkk, 555, LOL, jaja: Globalization Through Internet Jokes
by Nura Rutten in United Academics
In a recent article from Shifman, Levy and Thelwall, internet jokes are found to serve as an important and powerful agent of globalization and americanization. To research the role of internet jokes, they look at the concept of “user-generated globalization”, where internet users are the focal points through which user-generated content (in this case jokes) is translated, customized and distributed across the globe....

To Feed the World, Try Legos
by Elizabeth Preston in Inkfish
“It was an idea that just popped into my head,” says Ludovico Cademartiri, a materials scientist who’s upped his research game by using Legos. He hopes other researchers will steal his idea, and not just because Legos are fun. Cademartiri thinks the humble bricks could help solve the world’s impending food crisis. Members of Cademartiri’s […]The post To Feed the World, Try Legos appeared first on Inkfish.... Read more »

On Luck, Skill and Hard Work - in Soccer and Life
by Aurametrix team in Health Technologies
Big data doesn't always get us closer to truth. Especially if there a fair bit of luck involved. And many think this applies to football/soccer games (Sally and Anderson, for example, say that soccer results are 50% luck). Yet data analysis provides valuable, sometimes counter-intuitive insights into this beautiful sport and the science of winning and losing in general.How many measurable elements of a soccer game contribute to the outcome? 2014 FIFA world cup's statistics page displays scores c........

A clever use of SciPy’s ndimage.generic_filter for n-dimensional image processing
by Juan Nunez-Iglesias in I Love Symposia!
This year I am privileged to be a mentor in the Google Summer of Code for the scikit-image project, as part of the Python Software Foundation organisation. Our student, Vighnesh Birodkar, recently came up with a clever use of SciPy’s ndimage.generic_filter that is certainly worth sharing widely.
Vighnesh is tasked with implementing region adjacency graphs and graph based methods for image segmentation. He initially wrote specific functions for 2D and 3D images, and I suggested that he s........ Read more »

The Love Song of Philo T. Farnsworth

Philo Farnsworth, if the name sounds vaguely familiar than you might just be a Futurama watcher. If you don't watch and know who I'm talking about or even better are a fan then, "YAY!" and for those of you who don't know, don't sweat it you're not alone. One of the forgotten greats, Farnsworth should be a household name, namely because one of his biggest inventions is in practically every home.... Read more »
