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.

It’s an early lesson in genetics: we get half our DNA from Mom, half from Dad.
But that straightforward explanation does not account for a process that sometimes occurs when cells divide. Called gene conversion, the copy of a gene from Mom can replace the one from Dad, or vice versa, making the two copies identical.
Evolution in extreme environments has produced life forms with amazing abilities and traits. Beneath the waves, many creatures sport iridescent structures that rival what materials scientists can make in the laboratory.
Thanks in part to an anonymous $250,000 gift, the University of Pennsylvania‘s School of Engineering and Applied Science is opening the AddLab, a new additive manufacturing facility that will feature a suite of state-of-the-art 3-D printing tools.

Earth’s atmosphere is a complicated dance of molecules. The chemical output of plants, animals and human industry rise into the air and pair off in sequences of chemical reactions. Such processes help maintain the atmosphere’s chemical balance; for example, some break down pollutants emitted from the burning of fossil fuels.
Study after study has proven it true: exercise is good for you. But new research from University of Pennsylvania scientists suggests that exercise may have an added benefit for cancer patients undergoing chemotherapy.
