Researchers Decipher Climate Paradox from the Miocene
Topic: Climate
Summary: As the Antarctic ice sheet grew to its present-day size around 14 million years ago, other regions on Earth became warmer. Researchers have now discovered why.

Possible Exomoon Found
Topic: New Planets
Summary: Researchers have spotted the first signs of a potential 'exomoon.' It's presence cannot be confirmed because it was observed during a chance encounter of objects that will not occur again - but it is a step toward locating other moons around distant stars.

Study Resolves Controversy Over Nitrogen's Ocean 'Exit Strategies'
Topic: Biosphere
Summary: New findings may settle a decades-long debate over how nitrogen is removed from the ocean. Understanding nitrogen cycling is crucial to understanding the productivity of the oceans as well as the global climate.

First Earth-Size Planet In The 'Habitable Zone' of Another Star
Topic: New Planets
Summary: Using 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.

Climate Change Drove Evolution of Ice Age Predators
Topic: Biosphere
Summary: New scientific studies at the La Brea Tar Pits are probing the link between climate warming and the evolution of Ice Age predators, attempting to predict how animals will respond to climate change today.

Icebreaking Mars
Topic: Missions
Summary: NASA Scientists have outlined a new lander mission to Mars, dubbed ‘Icebreaker.' According to their study, the lander could soon be ready to drill beneath the surface of Mars and search for signs of past or present life.

Rare Fossilized 500 Million Years Old Embryos
Topic: Origin & Evolution of Life
Summary: Researchers have found rare fossilized embryos from the Cambrian period. Their methods of study may help with future interpretation of evolutionary history.

The Birth of a Saturn Moon
Topic: Saturn system
Summary: NASA's Cassini spacecraft has documented the formation of a small icy object within the rings of Saturn that may be a new moon.

Four-Eyed Daddy Longlegs Fossil Fills in Evolutionary Tree
Topic: Origin & Evolution of Life
Summary: New research indicates that primitive daddy longlegs had two pairs of eyes, adding significant details to the evolutionary story of this diverse and highly successful group.

An Ancient Impact that Dwarfs K-T
Topic: Meteorites, Comets and Asteroids
Summary: Scientists have identified a 3.26 billion-year-old impact crater that has a diameter up to two and a half times larger than the Chicxulub crater.
