MIT Cheetah 3

MIT have released another video of humans being mean to robots their Cheetah 3 quadruped robot navigating a range of obstacles blind (without image sensors), including running up debris filled stairs (haha, take that Daleks!) and enduring being poked with a big stick while running and minding it's own business!  

Spectral Invisibility Cloak

Researchers have demonstrated a new cloaking technique that is effective within broadband light illumination. The technique selectively transfers energy from certain colours of the light wave to other colours. In the example image above, green light energy reflected when light passes through the object is redirected to other parts of the spectrum, effectively cancelling out the colours reflected from an object, making it invisible to the observer.

The Rise Of USSD Apps In Africa

Unstructured Supplementary Service Data (USSD) is a protocol of the GSM standard form 1997, mostly used to allow simple queries to be sent and received to and from the mobile network, like requesting your account balance. The advent of mobile internet and smartphones have largely decimated the use of USSD in developed markets. However in Africa, where there is only 18% internet penetration, there is over 80% penetration of GSM mobile phones. As a result, developers have started using USSD as a widespread delivery mechanism for apps from banking to fertility tracking.
