NAI carries out collaborative research and education in astrobiology, the interdisciplinary<br />

science that seeks answers to these fundamental questions. It supports investigation of<br />

these issues on Earth and serves as a portal to space for the scientific community.<br />

A New Book from NAI's Peter Ward<br />

Prolific author Peter Ward leads the pack, speculating on "Life As We Do Not<br />

Know It..." The book contains a wealth of information and dazzling speculation<br />

drawn from the ranks of Ward's colleagues in the 16 research institutions that<br />

operate worldwide as NASA's Astrobiology Institute.<br />

Spitzer Telecope Data Suggest that Life's Building Blocks are<br />

Abundant<br />

Infrared astronomers are discovering that compounds called polycyclic aromatic<br />

hydrocarbons (PAHs) constitute one the largest reservoirs of carbon in space.<br />

New observations confirm that PAHs are abundant, even in distant galaxies.<br />

Investigator Doug Huggins notes that "This stuff contains the building blocks of<br />

life, and now we can say they're abundant in space. And wherever there's a<br />

planet out there, we know that these things are going to be raining down on it."<br />

For Teachers<br />

New Teacher Workshop from NAI's Marine Biological Laboratory Lead Team<br />

"Discover the Microbes Within!" is a 3-day workshop<br />

designed for high school and undergraduate<br />

educators. Participants will learn about the diverse<br />

ways that bacteria evolve and symbiotically interact<br />

with insects, in an environment that fosters close<br />

interactions with research scientists and other<br />

teachers. Basic topics and lesson plans cover insect<br />

collection, insect biodiversity, the mutualistic and<br />

parasitic bacteria (Wolbachia) that live within them,<br />

DNA extraction, and simple molecular biology and<br />

evolutionary analysis skills.<br />
