151105 -NASA Mission Reveals Speed of Solar Wind Stripping Martian Atmosphere
NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission has identified the process that appears to have
played a key role in the transition of the Martian climate from an early, warm and wet environment that might have supported
surface life to the cold, arid planet Mars is today. More HERE

NASA X-ray Telescopes Find Black
Hole May Be a Neutrino Factory The giant black hole at the center of the Milky Way may be producing mysterious particles called neutrinos.
If confirmed, this would be the first time that scientists have traced neutrinos back to a black hole. Read more HERE
Ecological Footprint Found to Be "Misleading"
141105 - Is humanity really
using 1.5 Earths? That is the central finding of the Ecological Footprint (EF), a widely cited global
sustainability indicator used by the United Nations and major NGOs around the world to estimate
the impact of human activity on the biosphere. But a paper published today in PLoS Biology finds the
method behind the Ecological Footprint "so misleading as to preclude its use in any serious
scientific or policy context."
Measuring the order and disorder of matter
An editorial in Nature Materials highlights work by SFI External Professor James Crutchfield and his colleague Dowman Varn for their information-theoretic measure of material structure. Their algorithmic
approach, described in an SFI working paper, aims to provide a framework for classifying “anything from perfect crystals
to totally amorphous materials,” according to the editorial.
material order and disorder is especially relevant for materials science in 2014, which is the International Year of Crystallography.

In 2010, NASA and the National Science Foundation asked the National Research Council to assemble a committee of experts
to develop an integrated national strategy that would guide agency investments in solar and space physics for the years 2013-2022.
That strategy, the result of nearly 2 years of effort by the survey committee, which worked with more than 100 scientists
and engineers on eight supporting study panels, is presented in the 2013 publication, Solar and Space... [more]
Like most areas of scholarship, mathematics is a cumulative discipline: new research is reliant on well-organized and
well-curated literature. Because of the precise definitions and structures within mathematics, today's information technologies
and machine learning tools provide an opportunity to further organize and enhance discoverability of the mathematics literature
in new ways, with the potential to significantly facilitate mathematics research and learning. Opportunities exist to... [more]
Kepler Discovers First Earth-Size Planet In The 'Habitable
Zone' of Another Star
NASA's Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting
a star in the "habitable zone" -- the range of distance from a star where liquid water
might pool on the surface of an orbiting planet. FULL STORY
Nuclear Physics : Exploring the Heart of Matter
A study by the Committee
on the Assessment of and Outlook for Nuclear Physics; Board on Physics and Astronomy (BPA); Division on Engineering and Physical
Sciences (DEPS); National Research Council; The principal goals of the
study, published in 2013, were to articulate the scientific rationale and objectives of the field and then to take a
long-term strategic view of U.S. nuclear science in the global context for setting future directions for the field. Nuclear
Physics: Exploring the Heart of Matter provides a long-term assessment of an outlook for nuclear physics. Download the report
