Our planet's most abundant mineral now has a name
Phys.org
Deep below the earth's surface lies a thick, rocky layer called the mantle, which makes up the majority of our planet's volume. For decades, scientists have known that most of the lower mantle is a silicate mineral with a perovskite structure that is stable under the high-pressure and high-temperature conditions found in this region. Although synthetic examples of this composition have been well studied, no naturally occurring samples had ever been found in a rock on the earth's surface.

Scientists have a new theory about the 1 billion year pause in evolution
Business Insider
The "boring billion," the long evolutionary pause when slime ruled the Earth, might be due to a planetary cooling-off period that stalled plate tectonics, a new study suggests. Scientists have long sought an explanation for this big hold-up. Now, researchers think they've found a possible cause: the planet itself.

Scientists ready to study magma formation beneath Mount St. Helens
University of Washington
University and government scientists are embarking on a collaborative research expedition to improve volcanic eruption forecasting by learning more about how a deep-underground feeder system creates and supplies magma to Mount St. Helens. They hope the research will produce science that will lead to better understanding of eruptions, which in turn could lead to greater public safety.

Scientists smash crystals and determine moon is older than previously thought
Los Angeles Times
The violent impact that created our moon may have occurred millions of years earlier than previously thought, according to new research. Previously, it was suggested that this massive impact occurred 100 million years after the solar system formed. H

New evidence of Earth's deep water cycle reveals a virtual buried ocean
KQED
Water is part of Earth's very definition as a planet. Clouds of water fill its atmosphere, oceans cover most of its surface, and groundwater is found everywhere underground. For the last century, geologists have been tracing the influence of water deeper and deeper into Earth’s interior.

Earth's major tectonic plates may be speeding up
Discovery News
The movement of Earth's major continental tectonic plates is speeding up, suggests a new study. The study, presented at the Goldschmidt Geochemistry Conference in Sacramento, California, challenges the idea that the rate of plate movement remains stable. "This is quite mind boggling," says Professor Kent Condie of the New Mexico Institute of Mining and Technology, who led the study.

API: US production outpaced petroleum demand in May
Oil & Gas Journal
U.S. crude oil production in May increased 14.7 percent from May 2013 to 8.3 million b/d—the highest level for the month since 1987 — according to a report from the American Petroleum Institute. Total U.S. petroleum deliveries, a measure of demand, meanwhile, increased 1.9 percent from last May to average 18.9 million b/d, the highest May deliveries in 6 years.

Extreme fracking: Drilling to the earth's core
Science 2.0
Activists who are against natural gas in the United States have invented a variety of problems; flaming tap water, earthquakes, headaches, even that it will cause the earth to deflate. Good thing they don't live in Norway, where energy extraction by the Nextdrill research project is going thousands of meters into the ground, in order to exploit another of nature's bounties: tinkering with the Earth’s molten core and radioactive isotopes in the Earth’s crust.

After oil, natural gas may be next on North American rails
Reuters
As politicians debate the dangers of a massive increase in oil carried by rail in North America, railroads and energy producers are considering the same for natural gas. Buoyed by the unexpected success of crude by rail, companies are beginning to consider transporting natural gas as remote drilling frontiers emerge beyond the reach of pipelines, executives said.

Few, if any, big impact craters remain to be discovered on Earth, new model finds
Phys.org
It is likely that most of the large impact craters on Earth have already been discovered and that others have been erased, according to a new calculation by a pair of Purdue University graduate students. "Over the past 3.5 billion years it is thought that more than 80 asteroids similar in size to, or larger than, the one which killed the dinosaurs have struck the Earth, leaving behind craters which are over 100 kilometers across, but our model suggests only about eight of these massive craters could still exist today," said Timothy Bowling, a graduate student in Purdue's Department of Earth, Atmospheric and Planetary Sciences.

Petroleum group: EPA moving too slowly on fuel mandate
Des Moines Register
A top oil and gas trade group criticized the agency in charge of overseeing the country's renewable fuels mandate for not yet announcing how much ethanol must be blended into the nation's gasoline supply this year, increasing uncertainty for those who must comply with the controversial requirement. The American Petroleum Institute, which represents 550 oil and natural gas companies, said the delay has left its members that are responsible for complying with the Renewable Fuel Standard (RFS) to guess how much ethanol they have to blend.

2014 outlook for Gulf of Mexico hurricane-related production outages
U.S. Energy Information Administration
Forecasting storm damage is inherently difficult because the overall impact during a hurricane season depends on the intensity of individual storms and the path that each one takes. Even a strong storm on the eastern seaboard likely won’t disrupt Gulf of Mexico (GOM) production, although it may wreak havoc for the region’s population and temporarily reduce energy demand. On the other hand, a more moderate storm whose path leads right through the middle of the GOM and goes onshore along the Gulf Coast could cause significant harm to oil and natural gas production offshore as well as refineries, gas processing plants, and power generating stations onshore.
