Congratulations to Dr. Jack Griffith, Distinguished Professor or Microbiology & Immunology and Biochemistry & Biophysics whose work was highlighted in a special NOVA scienceNOW video series (originally aired in July 2009).
Salt deposits that formed 250 million years ago hold tantalizing hints of early life.
Biophysicist Jack Griffith takes you on a narrated photo tour of quarter-billion-year-old water bubbles.
Jack Griffith answers questions about cellulose, DNA, and other organic bits found in Permian salt deposits.
If cellulose survived 250 million years on Earth, could it survive in salt deposits on Mars?
