Supervolcanoes on Mars
Sky & Telescope
When it comes to volcanoes, Mars has always outclassed Earth. At 22 kilometers above the surrounding plains, Olympus Mons is almost three times the height of Mount Everest. Mars' Alba Mons is one-third as wide as the United States (depending how you measure). But a new study in this a recent edition of Nature proposes that the largest volcanoes on Mars have gone unnoticed — until now.

Elsevier Announces EPIC
GS
Elsevier has announced the Earth and Planetary Innovation Challenge (EPIC). EPIC is a competition that invites the Earth and planetary science communities to come up with original ideas for innovative web-based tools to enrich the online article. The aim of this new innovation challenge is to generate ideas that will support the Earth and planetary science communities by helping authors to present their work in exciting ways, retaining rich data and presentation formats which will allow readers to get more from articles through creating tools to facilitate understanding, and providing additional context critical for thorough understanding. The winner will receive a prize of US$1000 and Elsevier hopes to develop the top idea for ScienceDirect (with potential application for the GeochemSoc/MetSoc journal GCA). The submission window opened Sept. 16 and closes Oct. 31. More information on the competition is available at www.elsevier-epic.com.

Iron in Earth's core weakens before melting
ScienceDaily
The iron in the Earth's inner core weakens dramatically before it melts, explaining the unusual properties that exist in the moon-sized solid center of our planet that have, up until now, been difficult to understand. Scientists use seismic waves — pulses of energy generated during earthquakes — to measure what is happening in the Earth's inner core, which at 6000 km beneath our feet is completely inaccessible.

Russian meteorite said as old as the solar system
UPI
The meteorite that exploded over a Russian city in February was around 4.56 billion years old, as old as the Solar System itself, a scientist says. Mikhail Marov of the Vernadsky Institute of Geochemistry and Analytical Chemistry said the age of the so-called Chelyabinsk meteor was determined by a technique called radiometric dating, observing the amount of radioactive isotopes and their decay byproducts in the meteorite.

X-ray technique can image nano-properties in real time
The Engineer
Scientists have developed a new imaging technique that looks inside an object and maps the three-dimensional distribution of its nano-properties in real time. Researchers claim the technique could have a wide range of applications across many disciplines, such as materials science, geology, environmental science and medical research.

Extrusive volcanism formed the Hawaiian Islands
ScienceDaily
A recent study by researchers at the University of Hawaii — Manoa (UHM) School of Ocean and Earth Science and Technology (SOEST) and the University of Rhode Island (URI) changes the understanding of how the Hawaiian Islands formed. Scientists have determined that it is the eruptions of lava on the surface, extrusion, which grow Hawaiian volcanoes, rather than internal emplacement of magma, as was previously thought.
