MIT researchers have developed an universal algorithm for a neural prosthetic aid that can link an individual's brain activity to the person's intentions, and then translate that intention into movement.
A gravity tractor, as envisioned by scientists, is a spacecraft that would hover over an asteroid on a collision course with Earth and, through gravitational attraction, accelerate or slow down the asteroid's rate of travel. By altering the speed, the gravity tractor could prevent the asteroid from striking Earth and wreaking environmental and economic havoc.
Mexico's Teotihuacan, once the center of a sprawling pre-Hispanic empire, is set to become the launch pad for an attempt to communicate with extraterrestrial life.

Scientists at Stanford University have demonstrated tangible proof that scientific experiments can be conducted using thousands of low-end PCs wrangled together into loosely linked networks.
A new report from the U.S. Department of Commerce predicts that with the proper investments in technology, futuristic scenarios such as mind uploading, or humans living past 100 years, or people linking their brains together to form a global collective intelligence could come to pass in this century.
