Tantalizing Hints About Extraterrestrial Life from NASA!

By: Susie77 , 11:25 PM GMT on November 29, 2010


WASHINGTON -- NASA will hold a news conference at 2 p.m. EST on
Thursday, Dec. 2, to discuss an astrobiology finding that will impact
the search for evidence of extraterrestrial life. Astrobiology is the
study of the origin, evolution, distribution and future of life in
the universe.

The news conference will be held at the NASA Headquarters auditorium
at 300 E St. SW, in Washington. It will be broadcast live on NASA
Television and streamed on the agency's website at

Participants are:
- Mary Voytek, director, Astrobiology Program, NASA Headquarters,
- Felisa Wolfe-Simon, NASA astrobiology research fellow, U.S.
Geological Survey, Menlo Park, Calif.
- Pamela Conrad, astrobiologist, NASA's Goddard Space Flight
Center, Greenbelt, Md.
- Steven Benner, distinguished fellow, Foundation for Applied
Molecular Evolution, Gainesville, Fla.
- James Elser, professor, Arizona State University, Tempe

Media representatives may attend the conference or ask questions by
phone or from participating NASA locations. To obtain dial-in
information, journalists must send their name, affiliation and
telephone number to Steve Cole at stephen.e.cole@nasa.gov or call
202-358-0918 by noon Dec. 2.

From NASA scientists discover all-new form of life | Geek Gestalt - CNET News:
In a press conference held at NASA's Washington D.C. headquarters, scientists announced that they had discovered a new form of bacteria, known as GFAJ-1, in California's Mono Lake that has DNA completely foreign to anything ever before found on Earth. It substitutes arsenic at the DNA level for phosphorus.

That would distinguish it from every other form of life known to man, all of which, no matter how diverse, is comprised of the same six elements, phosphorus, sulfur, carbon, hydrogen, oxygen, and nitrogen. But the bacteria found in Mono Lake--which is known for its unusual chemistry, including very high levels of salinity, alkalinity, and arsenic--is made partly of arsenic, and has no phosphorus in its DNA.

.... by discovering a microbe that has a new form of DNA, it forces scientists to question what they've long held as true--that all life was based on the same six components.
