Icelandic volcano sits on massive magma hot spot

Spectacular eruptions at Bárðarbunga volcano in central Iceland have been spewing lava continuously since Aug. 31. Massive amounts of erupting lava are connected to the destruction of supercontinents and dramatic changes in climate and ecosystems.

New research from UC Davis and Aarhus University in Denmark shows that high mantle temperatures miles beneath the Earth's surface are essential for generating such large amounts of magma. In fact, the scientists found that the Bárðarbunga volcano lies directly above the hottest portion of the North Atlantic mantle plume.

Climate change impacts countered by stricter fisheries management

A new study has found that implementing stricter fisheries management overcame the expected detrimental effects of climate change disturbances in coral reef fisheries badly impacted by the 1997/98 El Niño, according to the Wildlife Conservation Society.

Satellite catches lingering remnants of Tropical Depression 9

NOAA's GOES-East satellite has been keeping an eye on the remnants of Tropical Depression 9.

On Oct. 24 at 14:30 UTC (10:30 a.m. EDT) GOES-East captured a visible image of clouds and thunderstorms associated with former Tropical Depression 9,, centered over the southeastern Yucatan Peninsula of Mexico, Belize, and the adjacent northwestern Caribbean Sea.

Li-ion batteries contain toxic halogens, but environmentally friendly alternatives exist

Physics researchers at Virginia Commonwealth University have discovered that most of the electrolytes used in lithium-ion batteries — commonly found in consumer electronic devices — are superhalogens, and that the vast majority of these electrolytes contain toxic halogens.

At the same time, the researchers also found that the electrolytes in lithium-ion batteries (also known as Li-ion batteries) could be replaced with halogen-free electrolytes that are both nontoxic and environmentally friendly.

Liquid helium offers a fascinating new way to make charged molecules

A collaboration between researchers at the Universities of Leicester and Innsbruck has developed a completely new way of forming charged molecules which offers tremendous potential for new areas of chemical research.

Bodies at sea: Ocean oxygen levels may impact scavenger response

An ocean's oxygen levels may play a role in the impact of marine predators on bodies when they are immersed in the sea, according to Simon Fraser University researchers in a new study published this week in the journal PLoS One.

SFU criminologist Gail Anderson led the study, based on the deployment of a trio of pig carcasses into Saanich Inlet at a depth of 100 metres and studied over the past three years. Anderson assessed scavenger activity while co-author and SFU criminologist Lynne Bell continues her investigation of what happens to submerged bones.

New experiment provides route to macroscopic high-mass superpositions

University of Southampton scientists have designed a new experiment to test the foundations of quantum mechanics at the large scale.

Standard quantum theory places no limit on particle size and current experiments use larger and larger particles, which exhibit wave-like behaviour. However, at these masses experiments begin to probe extensions to standard quantum mechanics, which describe the apparent quantum-to-classical transition.

New insights on carbonic acid in water

Though it garners few public headlines, carbonic acid, the hydrated form of carbon dioxide, is critical to both the health of the atmosphere and the human body. However, because it exists for only a fraction of a second before changing into a mix of hydrogen and bicarbonate ions, carbonic acid has remained an enigma. A new study by Berkeley Lab researchers, has yielded valuable new information about carbonic acid with important implications for both geological and biological concerns.

Tropical Depression 9 forms in Gulf of Mexico

Tropical Depression Nine formed over the western Bay of Campeche, Gulf of Mexico and is forecast to make a quick landfall on Mexico's Yucatan Peninsula. NOAA's GOES-East Satellite captured the birth of the depression.

NOAA's GOES-East Satellite captured an image of the birth of Tropical Depression 9 on Oct. 22 at 1600 UTC (12 p.m. EDT) in the western Bay of Campeche. The clouds associated with the depression stretched over the Yucatan Peninsula and into the western Caribbean Sea.

Recently discovered microbe is key player in climate change

Tiny soil microbes are among the world's biggest potential amplifiers of human-caused climate change, but whether microbial communities are mere slaves to their environment or influential actors in their own right is an open question. Now, research by an international team of scientists from the U.S., Sweden and Australia, led by University of Arizona scientists, shows that a single species of microbe, discovered only very recently, is an unexpected key player in climate change.

Researchers resolve the Karakoram glacier anomaly, a cold case of climate science

Researchers from Princeton University and other institutions may have hit upon an answer to a climate-change puzzle that has eluded scientists for years, and that could help understand the future availability of water for hundreds of millions of people.

New study shows that shifting precipitation patterns affect tea flavor, health compounds

BOZEMAN, Mont. – A team of researchers including Montana State University professor Selena Ahmed has found that shifting patterns of precipitation affect key chemicals responsible for the flavor and health properties of tea.

Harvard study offers first-ever look at how NCAA concussion guidelines are followed

Though most NCAA colleges and universities have created programs to help athletes deal with concussions, a new Harvard study has found that, when it comes to specific components of those plans, many institutions still lag behind accepted standards.

The study, the first-ever comprehensive examination of how colleges and universities have complied with the Concussion Policy and Legislation adopted by the NCAA in 2010, is based on the results of a survey sent to all 1,066 NCAA member institutions. Of those institutions, 907 schools responded.

Rising above the risk: America's first tsunami refuge

Boulder, CO, USA — Washington's coast is so close to the seismically active Cascadia Subduction Zone that if a megathrust earthquake were to occur, a tsunami would hit the Washington shoreline in just 25 minutes.

One coastal community is preparing for such a disaster by starting construction on the nation's first tsunami evacuation refuge, large enough to shelter more than 1,000 people who are within 20-minute walking distance.

Backpack physics: Smaller hikers carry heavier loads

WASHINGTON, D.C., October 21, 2014 -- Hikers are generally advised that the weight of the packs they carry should correspond to their own size, with smaller individuals carrying lighter loads. Although petite backpackers might appreciate the excuse to hand off heavier gear to the larger members of the group, it turns out that they may not need the help.
