When life began on Earth, iron may have done the job of magnesium, making life possible.

On the periodic table of the elements, iron and magnesium are far apart. But new evidence discovered by NAI's team at the Georgia Institute of Technology suggests that three billion years ago, iron did the job magnesium does today in helping Ribonucleic acid (RNA), a molecule essential for life, assume the molecular shapes necessary for biology.

The results of the study were published online on May 31, 2012 in the journal PLoS ONE.

There is considerable evidence that the evolution of life passed through an early stage when RNA played a more central role, doing the jobs of DNA and protein before they appeared. During that time, more than three billion years ago, the environment lacked oxygen but had lots of available iron.

"One of the greatest challenges in astrobiology is understanding how life began on Earth billions of years ago when the environment was very different than it is today," said Carl Pilcher, director of the Astrobiology Institute at NASA's Ames Research Center, Moffett Field, Calif. "This study shows us how conditions on early Earth may have been conducive to the development of life."

In the new study, researchers from the Georgia Institute of Technology, Atlanta, used experiments and numerical calculations to show that under early Earth conditions, with little oxygen around, iron can substitute for magnesium in RNA, enabling it to assume the shapes it needs to catalyze life's chemical reactions. In fact, it catalyzed those reactions better with iron than with magnesium.

NASA and the Library of Congress have announced the selection of David H. Grinspoon to be the first Baruch S. Blumberg NASA-Library of Congress Chair in Astrobiology.

The chair, selected through an international competition, is named for the late Nobel Laureate and founding director of the NASA Astrobiology Institute, Baruch "Barry" Blumberg. Applications are solicited by the Library of Congress and reviewed by a panel jointly established by the Library and NASA. The prestigious position was created in November 2011.

Grinspoon will be in residence for a year beginning November 2012 at the library's scholarly research organization, the Kluge Center, in Washington, D.C.. He is the curator of astrobiology in the Department of Space Sciences at the Denver Museum of Nature and Science. Grinspoon is a well-known researcher in planetary science and the author of the award-winning book "Lonely Planets: The Natural Philosophy of Alien Life."

"Grinspoon's background as an astrobiology researcher, writer and communicator of science makes him an ideal choice," said Carl Pilcher, director of the Astrobiology Institute at NASA's Ames Research Center at Moffett Field, Calif. "This is certainly the start of what will become a great tradition of astrobiology chairs at the library."

The National Aeronautics and Space Administration (NASA) Science Mission Directorate (SMD) intends to release a Program Element Appendix (PEA) of the Stand Alone Missions of Opportunity Notice (SALMON-2), with a target date of June 28, 2012. This PEA will solicit proposals for instrument investigations to be implemented through the European Space Agency's (ESA) JUpiter ICy moons Explorer (JUICE) mission.

NASA has allocated $100 Million RY budget over the full life cycle of the mission for a limited portion of the JUICE payload. The NASA contribution would consist of a combination of 1) U.S.-led instrument(s), 2) U.S.-provided instrument component(s) for European-led instrument(s), and/or 3) U.S. Co-Investigators on European-led instruments, all to total not more than $100M life cycle cost. Only proposals for the first type of contribution (i.e., U.S. PI-led instrument investigations) should be submitted to this PEA. Proposals with the latter two types of U.S. contributions (i.e., proposals led by a non-U.S. PI) should respond to the ESA AO released in conjunction with this PEA.

Participation in this PEA will be open to all categories of organizations (foreign and domestic, with the exception that European Principle Investigators must submit their proposals to a separate Announcement of Opportunity to be released by ESA), including educational institutions, industry, not-for-profit organizations, Federally Funded Research and Development Centers (FFRDC's), NASA Centers, the Jet Propulsion Laboratory (JPL), and other Government agencies. Principal Investigators are responsible for and allowed to assemble the instrument team from any and all of these organizations.

Poipu, Kauai, Hawaii, February 25-27, 2013

Contributed talks (30 min) and poster presentations are invited for the 'First Workshop on Experimental Laboratory Astrophysics' in Poipu, Kauai, Hawaii, February 25-27, 2013. During the last decade, significant new experimental techniques have been developed to investigate the interaction of ionizing radiation (UV, VUV, gamma rays, charged particles) and of neutrals (atoms, radicals, molecules, grains) with surfaces of solids (ices, minerals, carbonaceous compounds) in the Solar System and in the Interstellar Medium (ISM). These processes provide new fundamental insights - sometimes on the molecular level - into the processes that are critical to the chemistry in the ISM, star and planet forming regions, and on/in icy objects in the Solar System from the formation of the simplest molecule (molecular hydrogen) to astrobiologically important species such as amino acids and sugars.

The first workshop features invited (senior and junior researchers) as well as contributed talks and poster presentations focusing on the interaction of ionizing radiation (UV, VUV, gamma rays, charged particles) and neutrals (atoms, radicals, molecules, grains) with low temperature solids (ices, minerals, organics).

Additional information will be posted soon.
