Science Nation - Super Stars

submitted by: nsf
Who are the biggest super stars in the universe? For Adam Burrows, an astrophysics professor at Princeton University, it's not who, but "what," and they are far from Hollywood, or even earth, for that matter. Burrows would tell you biggest super stars are the stars that die in a massive explosion called a "supernova." With support from the National Science Foundation, Burrows investigates supernovae and he has recently created 3D computer simulations showing the actual moment of a star's...

Cell-Cell Communication in Bacteria: Part 2: Vibrio Cholerae Quorum Sensing and Developing Novel Antibiotics (19:49)

submitted by: scivee-team
Bacteria, primitive single-celled organisms, communicate with chemical languages that allow them to synchronize their behavior and thereby act as enormous multi-cellular organisms. This process is called quorum sensing and it enables bacteria to successfully infect and cause disease in plants, animals, and humans. Investigations of the molecular mechanisms underlying quorum sensing are leading to the development of novel strategies to interfere with quorum sensing. These strategies form the...
