By Madeleine Stone On Wednesday, Oct. 22, the University of Pennsylvania’s Nano/Bio Interface Center hosted its annual NanoDay@Penn, a public education and outreach event that featured a series of talks, demonstrations and exhibits concerning nanotechnology, a rapidly expanding scientific discipline that involves the manipulation of matter on the atomic and molecular scale.

One of the biggest mysteries in modern science is the speed at which the universe is expanding. Galaxies that have been moving apart since the Big Bang billions of years ago should be slowing down due to gravity, but instead, they are accelerating.

The brain has a complex system for keeping track of which direction a person is facing as he or she moves about; remembering how to get from one place to another would otherwise be impossible.

The brain has a complex system for keeping track of which direction you are facing as you move about; remembering how to get from one place to another would otherwise be impossible. Researchers from the University of Pennsylvania have now shown how the brain anchors this mental compass.
