Chemical studies on the possible existence of life on Mars.
Although there is no direct evidence yet for the existence of life on Mars, it is reasonable to conclude that the emergence of life on Earth, which appears to have been controlled by universal laws of physics and chemistry, may have been repeated elsewhere in the universe.  The dual approach of synthesis and analysis in our experimental studies has provided ample evidence in support of this hypothesis.
