How mineral crystals affected early life and developing an interest in ET at age 10

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Abodes - Scientists studying climate change in Antarctica are showing how global warming and loss of sea ice are affecting many facets of the food chain. Interestingly, at the base of the food chain, Antarctic phytoplankton is responding in two contrasting ways. See article.
g Life - What do we have in common with a crystal chandelier? We’re both made of material that replicates its own structure. In our case it’s DNA, while the crystals in the chandelier grew from minerals like quartz. One scientist thinks for early life on Earth, certain mineral crystals played the role that DNA does for us today. See article.
g Learning - SETI scientist Seth Shostak says he developed an interest in extraterrestrial life at the tender age of ten, when he first picked up a book about the solar system. See article.
