Video Friday: Arsenic Munching Bugs!

An extremely topical video this week.  The Periodic Table of Video’s Martyn Poliakoff discusses whether arsenic can replace phosphorous in DNA and other biomolecules.  This is following the discovery of bacteria that can survive in arsenic rich environments and possibly incorporate the arsenic into their molecules in place of phosphorus.    If you wish to read more (and in particular read the wealth of comment that has been written online about this work), I suggest BoraZ’s link dump over at A Blog Around the Clock.
