AbGradE (Astrobiology Graduates in Europe) held its first symposium in Edinburgh, UK, 10–11 October. The symposium started with an icebreaker event and consisted of two days of scientific sessions combined with networking, a round table, and a public outreach and education event. Approximately 40 enthusiastic and motivated early-career astrobiologists from all over Europe and beyond attended the symposium, presenting their work followed by discussions that enhanced sharing ideas with their contemporaries.
With the success of the first symposium, the committee is planning to hold the symposium biyearly along with the EANA meeting. For more information on AbGradE, visit: http ...December 9, 2014 / Written by: Julie Fletcher

The evolution of multicellular life on Earth happened with a number of key transitions from simple organisms to complex. Could the same transitions happen on other worlds? Frank Rosenzweig, an evolutionary geneticist at the University of Montana, is looking into such questions over the next five years with funding from the NASA Astrobiology Institute. His lab studies how life evolves “complex traits,” factors that influence everything from lifespan to biodiversity.
Rosenzweig’s previous NASA funding came from the Exobiology and Evolutionary Biology Program ...

NASA has performed a flawless first flight test of the Orion capsule. Orion is being developed to carry humans to deep space. The expanded launch capabilities of the Orion program could also enable future science missions that are even larger and more capable than previous robotic explorers, which have shaped our understanding of Mars and other bodies throughout the Solar System.

NAI astrobiologists from the Virtual Planetary Laboratory at the University of Washington, graduate student Rodrigo Luger and professor Rory Barnes, have shown that many terrestrial planets in the habitable zones of low mass (M dwarf) stars could have experienced extreme stellar heating for up to 1 billion years after planet formation. This could lead to oceanic evaporation and atmospheric oxygenation. The study has been accepted for publication in Astrobiology.

Scientists have programmed a robotic arm to poke the sample with an acupuncture needle. Credit: GA Tech
Researchers have turned to acupuncture in order to study samples from rough and uneven surfaces, such as rocks and meteorites. Using the technique, scientists have developed a robotic system that can collect samples from these non-planar surfaces.
The system uses a 3-D camera mounted on a robotic arm to map the irregular surface of an object. Then an acupuncture needle pokes and probes a tiny spot selected by the scientists. A minuscule amount of material is collected at the tip ...November 27, 2014 / Written by: Aaron Gronstal

How likely is habitability on icy worlds, and how would we search for it? This is one of the questions driving a research team led by Isik Kanik at NASA’s Jet Propulsion Laboratory.
Kanik’s team was selected for a new grant from the NASA Astrobiology Institute for a five-year project looking at how metabolism could come about by way of chemical differences on icy worlds, and ...

Astrobiologists have shown that the formation of RNA from prebiotic reactions may not be as problematic as scientists once thought.
One hypotheses for the origin of life on Earth includes a period known as the 'RNA World.’ In this proposed scenario, ribonucleic acid (RNA) formed from non-biological reactions, and then became incorporated into life’s first cells.
The study presents a proof-of-concept system that could overcome previously sited challenges to the RNA World hypothesis, and was published in the Journal of the American ...November 21, 2014 / Written by: Aaron Gronstal

Scientists have confirmed the existence of a process that causes the electrolysis of water, and which has the potential to drive the production of life in 'Snowball Earth’ scenarios and on icy satellites such as Europa and Enceladus.
The process, known as the Workman-Reynolds Effect (WRE), occurs when a dilute aqueous solution of salt rapidly freezes, causing ions in the solution to assume a negative or positive charge at the interface between ice and water.

The European Space Agency (ESA) has successfully performed the first soft landing on a comet. The Rosetta mission delivered the Philae lander to comet 67P/Churyumov-Gerasimenko on November 12, 2014. The first two images from the lander have now confirmed that the craft is safely positioned on the comet.

For two days in September, a group of scientists, historians, philosophers and theologians from around the world explored how we might prepare for the inevitable discovery of life — microbial or intelligent — elsewhere in the Universe. The event was sponsored by the NASA Astrobiology Program and the Library of Congress.
If microbial life can survive in Earth’s Atacama Desert (right), one of the driest places on the planet, would it have any chance on Mars (left)? From a perspective of the availability of water for biological activity, or “water activity,” as reviewed in a new study, the answer is “yes.” Credit: NASA/JPL (left); Henry Bortman (right)
Life as we know it requires water for the complex chemistry that enables growth and reproduction. But how much water at a minimum does life need? A recent study in the journal Environmental Microbiology explains that it is not ...

New research could explain why it took around a billion years for animal species to flourish on Earth after oxygen levels in the atmosphere began to increase.
Animal life on Earth boomed around 800 million years ago at the end of the Proterozoic period, but scientists have long believed that there was sufficient oxygen in the atmosphere for this increase in animal diversity to occur much earlier. However, new findings published in the journal Science show that oxygen levels were only 0.1% of those we see ...October 30, 2014 / Posted by: Aaron Gronstal

How habitable was Mars in the past? Since the Curiosity rover touched down on Mars in August 2012, it has helped answer a few of these questions in the area surrounding its equatorial landing site of Gale Crater.
Mars 2020, as it’s currently called, will have improved instruments over Curiosity. The new rover is heavily based on the Curiosity design, and as with its predecessor it will ...
