Harvard University selected XVIVO to develop an animation that would take their cellular biology students on a journey through the microscopic world of a cell, illustrating mechanisms that allow a white blood cell to sense its surroundings and respond to an external stimulus. This award winning piece was the first topic in a series of animations XVIVO is creating for Harvards educational website BioVisions at Harvard.

Today we are launching code.nasa.gov, the latest member of the open NASA web family. Through this website, we will continue, unify, and expand NASA’s open source activities. The site will serve to surface existing projects, provide a forum for discussing projects and processes, and guide internal and external groups in open development, release, and contribution.
By watching evolution in progress, scientists reveal key developments in the evolution of complex life and put evolutionary theories to the test

Very short computer programs, sometimes consisting of as few as three arithmetic operations in an infinite loop, can generate data that sounds like music when output as raw PCM audio. The space of such programs was recently explored by dozens of individuals within various on-line communities. This paper discusses the programs resulting from this exploratory work and highlights some rather unusual methods they use for synthesizing sound and generating musical structure.

A crack team of neuroscientist engineers from the University of Minnesota have created the first brain-computer interface (BCI) that allows the human user to navigate a 3D space. In testing, subjects flew a virtual helicopter through randomly-placed rings with an 85% success rate, and at an impressive speed: some testers managed to fly through 11 consecutive rings within five minutes.

We are players in a game we don’t understand. Most of our own thinking is below awareness. Fifty years ago, people may have assumed we are captains of our own ships, but, in fact, our behavior is often aroused by context in ways we can’t see. Our biases frequently cause us to want the wrong things. Our perceptions and memories are slippery, especially about our own mental states. Our free will is bounded. We have much less control over ourselves than we thought.
