Cubli the Robotic Cube Jumps Up, Balances, Walks

Cubli is a tiny cube, measuring just 6 inches for each side. But the tiny little cube is darn impressive, especially given its ability to maintain its balance. Cubli can balance itself on its corner, then you could push, goad, spin the little cube or even dramatically change the angle of the surface it sits on, but the cube staunchly refuses to budge.

India’s Mars Orbiter Sends Home Its First Image

First image of earth from Indias Mars Orbiter Mission

India’s first mission to Mars, the Mars Orbiter (Mangalyaan) crossed the distance of the moon’s orbit this morning, making it the farthest object sent into space by India. A few days ago, the spacecraft looked back, and sent a postcard back home. This is the first image of Earth taken by the Mars Color Camera (MCC) aboard the Mars Orbiter Spacecraft. The image was taken on November 19, from an altitude of 67975 kilometers.

Prepare yourself for new royalty shaped in the form of mice. But that’s not just any mice, these are mice with the DNA of the king of rock and roll. For his “All That I Am” project, Koby Barhad used the DNA of Elvis Presley in genetically engineered mice. The idea is to explore ethical and philosophical concerns, ranging from questions of talent, to the ownership and legal rights tied to using someone else’s genetic data.
