RNA Affinities and the Origin of Life
Topic: Origin & Evolution of Life
08/03/13
Summary: A new study outlines how chemical components involved in the origin of life may have primed and protected each other in never-before-realized ways.

Choosing an Orbit for TESS
Topic: Missions
08/02/13
Summary: NASA engineers are fine-tuning their orbital selection for the Transiting Exoplanet Survey Satellite (TESS). From a never-before-used orbit between the Earth and the Moon, TESS will map the locations of more than 500 transiting exoplanets.

Kick Starter for Primitive Chemistry
Topic: Origin & Evolution of Life
08/02/13
Summary: Three new papers strengthen the case the life on Earth first began at alkaline hydrothermal vents at the bottom of the oceans.

A Young, Hula-Hooping Star
Topic: Cosmic Evolution
08/01/13
Summary: Astronomers have spotted a young stellar system that 'blinks' every 93 days. The system likely consists of three developing stars. Two of the stars have a disk of material that surrounds them like a hula hoop.

'Runaway Greenhouse' Easily Triggered
Topic: Climate
08/01/13
Summary: A new study indicates that it might be easier than previously thought to initiate a 'runaway greenhouse' on planets. The research could change our understanding of the habitable zone around stars, and provide clues about how Earth's climate will change in the future as the Sun's brightness increases.

Seeing Photosynthesis from Space
Topic: Biosphere
07/31/13
Summary: NASA scientists have found a new way to use satellites to measure what's occurring inside plants at a cellular level.

Comet of the century?
Topic: Meteorites, Comets and Asteroids
07/31/13
Summary: A new study indicates that the approach of Comet C/2012 S1 ISON may not be as spectacular as scientists first thought. It is possible that the comet will disintegrate as it nears the Sun.

Rising Temperatures Boost Carbon Dioxide in the Tropics
Topic: Climate
07/30/13
Summary: A new study shows that generation of carbon dioxide in tropical ecosystems increases when temperatures rise, unlike ecosystems in other parts of the world.

Eclipsing Planet Seen in X-Rays
Topic: New Planets
07/30/13
Summary: X-ray observations have been used to observe a transiting exoplanet for the first time. The discovery is important because using X-rays to spot a planet can reveal additional information about the planet's properties.

Controlling Rovers from Space
Topic: Robotics & A.I.
07/29/13
Summary: NASA recently tested technology that could allow astronauts in orbit around bodies like Mars perform work on the surface of the planet using robotic avatars.
