Proof of Evolution Is in Your DNA

Another great video from our friend Dr. Joe Hanson and the team behind the video series It’s Okay to Be Smart, brought to you by PBS Digital Studios. This time, we’re looking at the proof of evolution that’s embedded right there in our DNA. According to Dr. Hanson, “Humans are special, and we got that way thanks to evolution and natural selection. The proof is right there in our bodies! From anatomy to genes, here are some stories of how you got to be the way you are.” Evolution of…

Studying the Dolphin Genome for Human Health

Studying the dolphin genome is revealing information that could benefit human health. Scientists are building a database full of dolphin genetic data. By Kate Stone Humans have long been enamored with dolphins. There is something irresistible about dolphins’ playfulness and agility in the water. We portray them in television and film as heroes saving humans from danger through remarkable feats of strength and tenacity. Some people have reported that dolphins saved them from drowning or shark attacks. Now, dolphins may save humans, thanks to a database full of genetic data.…

Nuclear Magnetic Resonance: A Dynamic View of Life

By Florian Celli Florian Celli is a PhD student of biophysics in the Center for Atomic Energy (CEA of Saclay) and the Synchrotron SOLEIL in Paris. He uses nuclear magnetic resonance to study protein dynamics in order to understand their biological role. He co-writes 2 Steps From Science, a website of general science in French and English for students and science fans. Follow on Twitter and Facebook.

Comet Carries Building Blocks of Life

Many of us learned in school that comets were lifeless balls of frozen gas and dust hurtling through space. In recent years, however, we have changed the way we think about comets, which are now thought to be the couriers that delivered life to a young Earth. Boosting the courier theory, the European Space Agency’s comet-chaser craft named Rosetta has found complex organic molecules, the building blocks of life, on a comet. These are the exciting initial results of the data analysis using the information returned by Rosetta’s lander, Philae,…
