New Life on Earth - HORIZON, Eight Arizona PBS

All known life on earth requires phosphorus as an essential nutrient. However, the discovery of a bacteria that uses the normally toxic element of arsenic instead of phosphorus is changing thoughts on what life on other planets might need to exist. A NASA-funded research team made the announcement about the new life on earth, and Arizona State University professors Paul Davies and Ariel Anbar co-authored the paper on the discovery. Both talk about their findings.
