Combined strategies help patients with adverse heparin reaction before heart surgery
New evidence suggests that therapeutic plasma exchange and appropriate blood testing could help patients who are in urgent need of heart surgery, but have a history of an adverse reaction to the blood thinner heparin, according to a study published online today in Blood, the Journal of the American Society of Hematology.

Small volcanic eruptions could be slowing global warming
Small volcanic eruptions might eject more of an atmosphere-cooling gas into Earth's upper atmosphere than previously thought, potentially contributing to the recent slowdown in global warming, according to a new study. (2014-11-18)

Research suggests warmth, flowing water on early Mars were episodic
There is ample evidence that water once flowed on the surface of ancient Mars. But that evidence is difficult to reconcile with the latest generation of climate models that suggest Mars should have been eternally icy. A new study by scientists from Brown University and the Weizmann Institute of Science suggest that warming and water flow on Mars were probably episodic and related to ancient volcanic eruptions.

Climate capers of the past 600,000 years
An international consortium of researchers under the auspices of the University of Bonn has drilled deposits on the bed of Lake Van (Turkey) which provide unique insights into the last 600,000 years. The samples reveal that the climate has done its fair share of mischief-making in the past. Furthermore, there have been numerous earthquakes and volcanic eruptions. In a special edition of the highly regarded publication Quaternary Science Reviews, the scientists now publish their findings. (2014-11-17)

Mysterious Midcontinent Rift is a geological hybrid
A team of geologists has a new explanation for the formation of the Midcontinent Rift, an ancient 2,000-mile-long underground crack that starts in Lake Superior and runs south. The rift is a geological hybrid, having formed in three stages: it started as an enormous narrow crack in the Earth's crust; that space then filled with an unusually large amount of volcanic rock; and, finally, the igneous rocks were forced to the surface, forming some of the Upper Midwest's beautiful scenery.

Discarded cigarette ashes could go to good use -- removing arsenic from water
Arsenic, a well-known poison, can be taken out of drinking water using sophisticated treatment methods. But in places that lack the equipment or technical know-how required to remove it, it still laces drinking water and makes people sick. To tackle this problem, scientists have come up with a new low-cost, simple way to remove arsenic using leftovers from another known health threat -- cigarettes. They report their method in the American Chemical Society's journal Industrial & Engineering Chemistry Research. (2014-10-15)

EARTH Magazine: Kilauea eruptions could shift from mild to wild
Hawaii's Kilauea volcano is famously effusive: Low-viscosity lava has been oozing out of the main caldera and two active rift zones along the southern shore of the Big Island since 1983. But scientists suspect that Kilauea's eruptions haven't always been so mild. In the past 2,500 years, at least two cycles of explosive eruptions lasting several centuries each have rocked the island. The switch from effusive to explosive is likely to occur again, scientists say, but probably not anytime soon. (2014-10-14)

Earth's magnetic field could flip within a human lifetime
A study by scientists from Italy, France, UC Berkeley and Columbia University demonstrates that Earth's last magnetic reversal took place 786,000 years ago and happened very quickly, in less than 100 years -- roughly a human lifetime. The rapid flip, much faster than the thousands of years most geologists thought, comes as new measurements show the planet's magnetic field is weakening 10 times faster than normal and could drop to zero in a few thousand years.

Living in the shadow of Mauna Loa: A silent summit belies a volcano's forgotten fury
Earth's largest active volcano, Mauna Loa on Hawaii's Big Island, is taking a nap. And after 30 years, no one is sure when the sleeping giant will awaken. Scientists say it's likely to erupt again within the next couple of decades and, when it does, it will be spectacular -- and potentially dangerous. (2014-09-08)

Citizen scientists saving lives around deadly 'Throat of Fire' volcano
Citizen scientists are saving the lives of people living in the shadow of deadly volcanoes according to research from the University of East Anglia. A report published today reveals the success of a volunteer group set up to safeguard communities around the 'Throat of Fire' Tungurahua volcano in the Ecuadorian Andes. The research shows that living safely in dangerous areas can depend on effective communication and collaboration between volcanologists, risk managers and vulnerable communities. (2014-08-22)

A global temperature conundrum: Cooling or warming climate?
When the Intergovernmental Panel on Climate Change recently requested a figure for its annual report, the University of Wisconsin-Madison's Zhengyu Liu knew that was going to be a problem. Writing in the journal Proceedings of the National Academy of Sciences today, Liu and his colleagues describe a consistent global warming trend over the course of the Holocene counter to a study published last year that described a period of global cooling before human influence.

A hellacious two weeks on Jupiter's moon Io
During a year-long series of observations of Jupiter's volcanically active moon, Io, UC Berkeley astronomers Imke de Pater and graduate student Katherine de Kleer observed within a two week period in August 2013 three of the largest outbursts ever seen on the moon, all probably involving lava erupting through fissures in curtains of fire. The observations by the Keck and Gemini telescopes in Hawaii suggest that outbursts are more common than previously thought. (2014-08-01)

New research reveals Pele is powerful, even in the sky
One might assume that a tropical storm moving through volcanic smog (vog) would sweep up the tainted air and march on, unchanged. However, a recent study from atmospheric scientists at the University of Hawai'i -- Manoa revealed that, though microscopic, gasses and particles from Kilauea volcano exerted an influence on Tropical Storm Flossie -- affecting the formation of thunderstorms and lightning in the sizable storm. (2014-07-28)

How much magma is hiding beneath our feet?
Molten rock, or magma, has a strong influence on our planet and its inhabitants, causing destructive volcanic eruptions and generating some of the giant mineral deposits. Our understanding of these phenomena is, however, limited by the fact that most magma cools and solidifies several kilometers beneath our feet, only to be exposed at the surface, millions of years later, by erosion.
