Often overlooked root vegetables such as turnips and rutabaga can have a major impact on the Earth’s ecosystem and biodiversity.

Human languages first appeared between 30,000 and 100,000 years ago, but the question of how languages spread and evolve is still under investigation. In this podcast from a recent SciCafe, join Museum curators Peter Whiteley and Ward Wheeler as they discuss how techniques used in genetic analysis are being applied to anthropology, language shifts, and key patterns in social evolution.
While supernovae are some of the most energetic phenomena known to science, a great deal of mystery still surrounds their origins. In this podcast from a recent “Frontiers in Astrophysics,” postdoctoral fellow Joanne Bibby and Richard Gilder Graduate School student Graham Kanarek introduce the theory that predicts massive stars as supernova progenitors, and discuss how scientists might confirm such a theory in the future.
The talk, “Spectacular Supernovae” was introduced by Department of Astrophysics Curator Michael Shara, and took place at the museum on October 15, 2012.
We’ve long understood black holes to be the points at which the universe as we know it comes to an end. Recent research, however, has led to new discoveries about black holes.
In this podcast from a recent “Frontiers in Astrophysics,” Caleb Scharf, Director of the Columbia Astrobiology Center, describes how these chasms in space-time don’t just vacuum up everything but release matter and rearrange the surrounding cosmos. Dr. Scharf’s talk took place at the Museum on September 10, 2012.
