Michael Storrie-Lombardi, M.D., from Kinohi Institute (Pasadena, CA), and Birgit Sattler, Ph.D., from the University of Innsbruck, Austria, used laser-induced fluorescence emission (L.I.F.E.) imaging to detect red and infrared fluorescence activity produced by cyanobacteria present in the ice of frozen Antarctic lakes. This noninvasive technique does not destroy individual target organisms or disrupt the structure of microbial communities or the surrounding ice matrix.

The study was conducted as part of the 2008 Tawani International Expedition to Schirmacher Oasis and Lake Untersee in Dronning Maud Land, Antarctica.

This L.I.F.E. technique, which required minimal, inexpensive, off-the-shelf equipment, demonstrated a promising, feasible strategy for detecting photosynthetic activity of microbes via orbital monitoring of ice formations on Earth, on Mars, and in frozen regions of planets in nearby star systems. The technique could also be employed by an interplanetary rover conducting on-site analyses and sample collection.

Deep Sea 'mushroom' Could Be Early Branch on Tree of Life

Reuters - Innovations Video Online (Oct. 24, 2014) Miniature deep sea animals discovered off the Australian coast almost three decades ago are puzzling scientists, who say the organisms have proved impossible to categorise. Academics at the Natural History of Denmark have appealed to the world scientific community for help, saying that further information on Dendrogramma enigmatica and Dendrogramma discoides could answer key evolutionary questions.
