Snowflakes photographed by new high-speed camera

submitted by: nsf
In the late 1800's, Wilson Bentley and Gustav Hellmann began photographing snowflakes. Their photos would go on to spark the public's fascination with snowflakes. Today University of Utah engineer Cale Fallgatter and atmospheric scientist Tim Garrett are using a new camera system that photographs free-falling snowflakes. The technology behind the camera that revealed the intricate, imperfect beauty of snowflakes can now expose their potential danger. About three years ago, a new...

MWV Episode 72 - Jonathan Eisen - Evolvability, the Built Environment and Open Science

submitted by: MicrobeWorld
Jonathan Eisen is an evolutionary biologist, currently working at University of California, Davis and is the academic editor-in-chief of the open-access journal PLoS Biology. On this episode, Jonathan talks about "evolvability," the probability that organisms can invent new functions. To do this, he has been using genome data in conjunction with experimental information to try and understand the mechanisms by which new functions have originated. Another area of interest for Eisen is the...
