The bend in the Appalachian mountain chain is finally explained
The 1500 mile Appalachian mountain chain runs along a nearly straight line from Alabama to Newfoundland -- except for a curious bend in Pennsylvania and New York State. Researchers from the College of New Jersey and the University of Rochester now know what caused that bend -- a dense, underground block of rigid, volcanic rock forced the chain to shift eastward as it was forming millions of years ago.

EARTH Magazine: Parasites spread across the Arctic under the 'new normal'
The last several decades have seen Arctic sea-ice minimums drop by more than half in area and more than three-quarters in volume. With current models predicting further reductions, scientists are calling it the 'new normal' and are trying to grasp its implications -- one of which is the occurrence of pathogens never before seen in the Arctic.

Australia's deadly eruptions the reason for the first mass extinction
A Curtin University researcher has shown that ancient volcanic eruptions in Australia 510 million years ago significantly affected the climate, causing the first known mass extinction in the history of complex life. Published in prestigious journal Geology, Curtin's Associate Professor Fred Jourdan, along with colleagues from several Australian and international institutions, used radioactive dating techniques to precisely measure the age of the eruptions of the Kalkarindji volcanic province.

On the shoulder of a giant: Precursor volcano to the island of O'ahu discovered
Researchers recently discovered that O'ahu, Hawai'i, actually consists of three major Hawaiian shield volcanoes, not two, as previously thought. Extending almost 100 km WNW from the western tip of the island of O'ahu is the submarine Ka'ena Ridge, a region that has now been recognized to represent a precursor volcano to the island of O'ahu, and on whose flanks the Wai'anae and Ko'olau Volcanoes later formed.

Arctic study sheds light on tree-ring divergence problem
New research from San Francisco State University has found that changes in tree-ring density in the Arctic may be evidence of changes in light intensity during the trees' growth. The finding has direct implications for the tree-ring 'divergence problem,' in which the density of tree rings in recent decades has not kept pace with increases in temperature, as expected.

The Red Sea -- an ocean like all others, after all
Actually, the Red Sea is an ideal study object for marine geologists. There they can observe the formation of an ocean in its early phase. However, the Red Sea seemed to go through a different birthing process than the other oceans. Now, Scientists at the GEOMAR Helmholtz Centre for Ocean Research Kiel and the King Abdulaziz University in Jeddah were able to show that salt glaciers have distorted the previous models. The study was just published in the international journal Earth and Planetary Science Letters. (2014-05-06)

Hot mantle drives elevation, volcanism along mid-ocean ridges
Using data from seismic waves, scientists have shown that temperature deep in Earth's mantle controls the elevation and volcanic activity along mid-ocean ridges, colossal mountain ranges that line the ocean floor. The findings, published this week in Science, bolster the idea that warm mantle plumes are responsible for 'hot spot' volcanism, and shed new light on how temperature in the depths of the mantle influences the contours of the Earth's crust.

Men who started smoking before age 11 had fatter sons
Men who started smoking regularly before the age of 11 had sons who, on average, had 5-10 kg more body fat than their peers by the time they were in their teens, according to new research from the Children of the 90s study at the University of Bristol. The researchers say this could indicate that exposure to tobacco smoke before the start of puberty may lead to metabolic changes in the next generation. (2014-04-02)

Ancient volcanic explosions shed light on Mercury's origins
The surface of Mercury crackled with volcanic explosions for extended periods of the planet's history, according to a new analysis led by researchers at Brown University. The findings are surprising considering Mercury wasn't supposed to have explosive volcanism in the first place, and they could have implications for understanding how Mercury formed. (2014-04-02)

The Atlantic Ocean dances with the sun and volcanoes
Natural fluctuations in the ocean temperature in the North Atlantic have a significant impact on the climate in the northern hemisphere. These fluctuations are the result of a complex dance between the forces of nature, but researchers at Aarhus University can now show that solar activity and the impact of volcanic eruptions have led this dance during the last two centuries.
