Evidence of 3.5-billion-year-old bacterial ecosystems may be earliest sign of life on Earth
Fox News
Scientists have discovered what may be the earliest sign of life on Earth. Remains of nearly 3.5-billion-year-old bacteria has been found in north-west Australia. Evidence of the never-before-seen bacteria was found in sedimentary rocks in the remote Pilbara region, home to the world's oldest rock formations. "There was plenty of life from the 3.4 and 3.43 billion-year-old mark — this is pushing it further back," researcher David Wacey, from the University of Western Australia said.

Geologists find oldest, largest meteorite impact structure
Laboratory Equipment
The world's largest and oldest meteorite impact structure has been discovered through research on the formation of gold deposits in Western Australia's Eastern Goldfields.
Located in the eastern Yilgarn, the Watchorn Impact Structure is 560 km in diameter at its widest point and estimated to be more than 2.6 billion years old.
Solid profession: Geologists in demand as shale plays surge
Houston Chronicle
Geologist Barry Katz, Ph.D., and president of the Houston Geological Society, became interested in science in high school, and he liked being outdoors. Those interests led to his study of geology and culminated in earning a doctorate in marine geology and geophysics. "Everybody's hiring," Katz said. "There are approximately 4,000 geologists in Houston alone. Many are close to retirement. With the various shale plays around the country along with multiple sites in Texas, demand for geologists is high." So, who makes the best geologist?

Could volcanoes be driving Antarctic ice loss?
Agence France-Press via ABC Science
Accelerating ice loss from the Antarctic icesheet could be due in part to active volcanoes under the frozen continent's eastern part, a study has found.
From 2002 to 2011, the average annual rate of Antarctic icesheet loss increased from about 30 billion tons to about 147 billion tons, the UN's panel of climate scientists reported in September.

Breakthrough: The accidental discovery that revolutionized American energy
The Atlantic
The dramatic changes to the nation's energy outlook are as surprising as they are clear. Seven years ago, oil production was in steep decline and natural gas nearly as hard to find. Today, the United States produces over 7.7 million barrels of oil a day, up over 50 percent since 2006 and the most in nearly 25 years. The nation could pump more than eleven million barrels a day by 2020.

3-D-printed fossils and rocks could transform geology
LiveScience via Fox News
Whether they're cracking open rocks or scanning tiny changes in topography, geologists already work in three dimensions. But one of the most popular attractions at the Geological Society of America's annual meeting in Denver was a 3-D printer spitting out fossils, globes and fractured rocks.

Geologists simulate deep earthquakes in the laboratory
News FIX
More than 20 years ago, geologist Harry Green, now a distinguished professor of the graduate division at the University of California, Riverside, and colleagues discovered a high-pressure failure mechanism that they proposed then was the long-sought mechanism of very deep earthquakes (earthquakes occurring at more than 400 km depth). The result was controversial because seismologists could not find a seismic signal in the Earth that could confirm the results. Seismologists have now found the critical evidence.
Simple scaling theory used to better predict gas production in barnett shale wells
University of Texas at Austin via Phys.org
Researchers at The University of Texas at Austin have developed a simple scaling theory to estimate gas production from hydraulically fractured wells in the Barnett Shale. The method is intended to help the energy industry accurately identify low- and high-producing horizontal wells, as well as accurately predict how long it will take for gas reserves to deplete in the wells.
The physics and sounds of seismicity, or earthquake 'music'
KQED
Earthquakes are vibrations; we all know that. The little ones we get all the time in California occur in the form of high-frequency vibrations — sound — as much as the low-frequency vibrations we perceive as shaking. People typically describe them as being like the sound of a truck rumbling by or a large door slamming. Large earthquakes are another matter. Most of an earthquake's vibrations are too slow for our ears to hear. Wouldn't it be interesting to be able to hear those vibrations? A number of scientific programmers have been playing with this idea, and the results are tantalizing.

Worm's mysterious blue slime decoded?

Shooting out glowing blue slime is a pretty cool superpower. Parchment tube worms — a common marine animal — have this ability, and Dimitri Deheyn of the Scripps Institution of Oceanography at the University of California, San Diego is one of the researchers asking how they do it.
What did the Colorado Plateau look like 250 million years ago?
National Praks Traveler
What did the Colorado Plateau look like 250 million years ago? That's a question geologists hope to shed some light on via an ambitious project that is pulling rock cores up from as much as 1.5 kilometers down into the plateau's belly. The Colorado Plateau is an expansive region, taking in parts of Colorado, Utah, Arizona, and New Mexico. Within this geologic province are some of our most iconic national parks. What makes them so stunning is the geology from which they rise. Through the Colorado Plateau Coring Project, geologists hope to peer into buried layers of the plateau.
More than a year later, aftershocks continue in Costa Rica
Costa Rica Star
On the morning of Sept. 5, 2012, residents of Guanacaste were going about their business and preparing to celebrate Costa Rica's 191st anniversary of its independence from Spain when a powerful earthquake struck the Nicoya Peninsula. That seismic movement, which registered a magnitude of 7.6 on the Richter scale, is still producing aftershocks and striking fear in the hearts of locals and tourists more than a year later.
New generation of micro sensors for monitoring ocean acidification
National Oceanography Center, Southampton via Phys.org
The first step in developing a cost-effective micro sensor for long-term monitoring of ocean acidification has been achieved by a team of scientists and engineers. The new technology, that will measure pH levels in seawater, was developed by engineers from the National Oceanography Center. In its current form it can be used for on-board analysis of seawater samples, but the ultimate aim is to further develop the design so that it can be deployed for long periods of time in the ocean, taking in situ measurements.
