"Is there a way to create artificial zero-gravity? If not, how can we investigate (on Earth) the effects of zero-gravity on plants?"

Habitability of Planets Around M Dwarf Stars
Multidisciplinary work from members of NAI’s SETI Institute Team and a host of collaborators across the NAI re-examines what is known at present about the potential for a terrestrial planet forming within, or migrating into, the classic liquid–surface–water habitable zone close to an M dwarf star. Their new paper, published in the current issue of Astrobiology, presents the summary conclusions of an interdisciplinary workshop sponsored by NAI and convened at the SETI Institute in 2005.

Salinity of Europa's Ocean
New research from NAI’s SETI Institute Team published online in Icarus today outlines the empirical range of salt concentrations permitted for Europa’s ocean. Solutions within the range imply high, near-saturation salt concentrations and require a Europan ice shell of less than 15 km thick, with a best fit at 4 km ice thickness. The paper examines the implications for subsurface habitability.

Surviving STS-107
Rocco Mancinelli, PI of NAI’s SETI Institute Lead Team, and member of NAI’s NASA Ames Research Center Lead Team joined researchers from KSC and Ames, as well as NAI’s Former Director, Barry Blumberg, in studying populations of C. Elegans which survived the atmospheric breakup of STS-107 during it’s fatal re-entry. Their results are published in Astrobiology. Five canisters were recovered, and live animals were observed in four of them. This demonstrates not only...

Astrobiology: The Study of the Living Universe
Christopher Chyba and Kevin Hand of the NAI’s SETI Institute Lead Team have just published this article in the Annual Reviews of Astronomy and Astrophysics (ARAA). It reviews the habitability of the Galaxy in general and of planets and moons in particular, and summarizes current controversies in origins-of-life research and in evidence for the earliest life on Earth. It critiques certain “rare Earth” and “anthropic” arguments, and considers four approaches to deciding whether intelligent life exists elsewhere...

The Enigma of the Martian Soil
Amos Banin from NAI’s SETI Institute Team discusses the state of knowledge about the Martian soil in this week’s Science “Perspectives.” He looks specifically at information gained from past missions, and the role water processing may have played in soil formation.
