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...

Science Nation - IceCube

- Searching below the surface of Antarctica for the mysterious neutrino - There's nothing like temperatures that can reach minus 100 degrees Fahrenheit to keep you on your toes. For engineers Erik Verhagen and Camille Parisel, working in Antarctica on a project appropriately called "IceCube" is both challenging and exciting.

What Genomes Can Tell Us About the Past by Sydney Brenner - Part 2: (42:36)

submitted by: video_collector

In the second part of talk, I explore other clues that suggest that genomes are not at equilibrium. Some genes appear to be changing more slowly and these older "fossil" genes in modern day genomes may give us insight into the distant past. I also hope to convince you that many of the great mysteries in contemporary biology do not require big research labs but can be solved through "home genomics"- piecing together information through a computer, the internet, and an inquisitive mind.

What Genomes Can Tell Us About the Past by Sydney Brenner - Part 1: (39:06)

submitted by: video_collector
By looking at the light from distant galaxies and having well-established calibration methods, astrophysics can make hypotheses about the history of our universe. Do we have similar "rulers" in biology that could allow us to reconstruct the remote past and the evolution of species on this planet? The answer is likely "yes" and the clues are undoubtedly contained in the many whole genome sequences that are now available for inspection. However, it is critical to evaluate the assumptions that...
