Summary: A new paper shows that wood-boring clams serve as "ecosystem engineers," making the organic matter in the wood available to other animals that colonize wood falls in the deep waters of Monterey Canyon.

Testing Life's Origins around Deep Sea Vents
Topic: Origin & Evolution of Life
Summary: Scientists are exploring the theory that simple metabolic reactions could have led to the origin of life around hot springs on the sea floor.

Ancient Volcanic Explosions Shed Light on Mercury’s Origins
Topic: Mercury
Summary: More detailed data from MESSENGER shows that volcanoes exploded on Mercury for a substantial portion of the planet's history. The findings suggest Mercury not only had volatiles but held on to them for longer than scientists had expected.

Gusev Crater Once Held a Lake After All

From Martian Rocks, a Planet’s Watery Story Emerges
Topic: Mars
Summary: After 18 months on Mars, the rover Curiosity has taken more than 120,000 measurements of surface rocks and soil, painting a more detailed image of how much water was once on the Red Planet.

Ancient Fossil Reveals Oldest Known Circulatory System
Topic: Origin & Evolution of Life
Summary: A fossil creature buried in an "invertebrate version of Pompeii" more than half a billion years ago reveals the first-known cardiovascular system in exquisitely preserved detail.

Science Fiction Stories with Good Astronomy & Physics
Topic: Spaceship Earth
Summary: A selective list of short stories and novels that use more or less accurate science and can be used for teaching or reinforcing astronomy or physics concepts.

Mars Exploration in a Deep Mine
Topic: Extreme Life
Summary: Scientists are testing technologies for Mars exploration in a 1.3 kilometer-deep mine. The project is part of the Mars Analogues for Space Exploration (MASE) program.
