Yellowstone’s Electrical Conductivity Hints Volcano Plume is Bigger Than Thought

WASHINGTON — Geophysicists have made the first large-scale picture of the electrical conductivity of the gigantic underground plume of hot and partly molten rock that feeds the Yellowstone supervolcano. The image suggests that the plume beneath the volcanically active area—renowned today for geysers and hot springs—is even bigger than it appears in earlier images made with earthquake waves.

“It’s like comparing ultrasound and MRI in the human body; they are different imaging technologies,” says geophysics Professor Michael Zhdanov of the University of Utah in Salt Lake City. Zhdanov is principal author of the new study and an expert on measuring magnetic and electrical fields on Earth’s surface to find oil, gas, minerals and geologic structures underground. (more…)

Under Pressure: Germanium

Washington, D.C. — Although its name may make many people think of flowers, the element germanium is part of a frequently studied group of elements, called IVa, which could have applications for next-generation computer architecture as well as implications for fundamental condensed matter physics.

New research conducted by Xiao-Jia Chen, Viktor Struzhkin, and Ho-kwang (Dave) Mao from Geophysical Laboratory at Carnegie Institution for Science, along with collaborators from China, reveals details of the element’s transitions under pressure. Their results show extraordinary agreement with the predictions of modern condensed matter theory. (more…)

Researchers Report Potential for a Moderate New England ‘Red Tide’ in 2011

*Bloom could be suppressed by changes in ocean conditions in the Gulf of Maine*

Scientists from the NOAA-funded Gulf of Maine Toxicity (GOMTOX) project issued an outlook for a moderate regional bloom of a toxic alga that can cause ‘red tides’ in the spring and summer of this year, potentially threatening the New England shellfish industry. However, there are signs this year’s bloom could be suppressed by recent changes in ocean conditions in the Gulf of Maine.

An abundant seed population in bottom sediments has set the stage for a moderate bloom of the toxic alga Alexandrium fundyense. This organism swims in the water, and divides again and again to form a “bloom” or red tide, but it also produces dormant cells or cysts that fall to the ocean bottom at the end of these blooms where they remain until they germinate the next year to restart the process.

How Child Molesters Justify Their Actions

Men who sexually abuse children generally blame external factors to explain their actions and diminish their guilt. “Every reason they give is a cognitive distortion,” says Sarah Paquette, a student who investigated the issue as part of her master’s thesis at the Université de Montréal School of Criminology.

Gypsies: The Mystical Tribe

The International Roma, (Gypsy) Day was founded at the first World Gypsy Congress, which took place in London on April 8, 1971. The congress gathered representatives from 30 countries. The national symbols of the gypsies – the flag and the anthem – were approved at the congress. The gypsies of the whole world became one single nation.

There are six basic branches of gypsies in the world today: three western and three eastern branches. Roma, Sinti and Iberian gypsies are referred to the Western branch. The eastern group includes the Lom, the Dom and the Lyuli people. In addition, there are smaller groups of gypsies. There are several ethnographic groups of nomadic peoples in Europe. Their lifestyle is close to that of the gypsies, but their origin is different – the Irish Travellers, or the Yeniche people from Central Europe, for instance. Many specialists, who study nomadic nations, agree that the gypsy ethnos had been finally formed only by the 15^th century, when the gypsies were traveling from Byzantium to Europe. (more…)

Glaciers Contributing To Faster Sea-Level Rise

Melting mountain glaciers are contributing to sea-level rise faster than at any time in the last 350 years, according to new research published in Nature Geoscience.

A research team from the University of Exeter, Aberystwyth University, and Stockholm University undertook a survey of the 270 largest outlet glaciers of the South and North Patagonian Icefields of South America. (more…)

Anthropologist: Japan Will Rise Above This Disaster

“Japan will recover from the catastrophe that has hit its shores,” says Bernard Bernier, director of the Université de Montréal Department of Anthropology. “This will not be a turning point in the country’s history.” (more…)
