Scientists See Deeper Yellowstone Magma

University of Utah seismologists discovered and made images of a reservoir of hot, partly molten rock 12 to 28 miles beneath the Yellowstone supervolcano, and it is 4.4 times larger than the shallower, long-known magma chamber. The hot rock in the newly discovered, deeper magma reservoir would fill the 1,000-cubic-mile Grand Canyon 11.2 times.

Researchers Map Entire Genomes of Woolly Mammoths, Revealing More Clues to Cause of Extinction, Raising Possibility of Bringing Mammoths Back

An international team of researchers has sequenced the nearly complete genome of two Siberian woolly mammoths—revealing the most complete picture to date—including new information about the species’ evolutionary history and the conditions that led to its mass extinction at the end of the Ice Age.

Thawing Permafrost Feeds Climate Change

Assistant Professor of Oceanography Robert Spencer writes in Geophysical Research Letters that single-cell organisms called microbes are rapidly devouring the ancient carbon being released from thawing permafrost soil and ultimately releasing it back into the atmosphere as carbon dioxide. Increased carbon dioxide levels, of course, cause the Earth to warm and accelerate thawing.

Researchers Make Breakthrough in Detecting Most Common Bacteria Contaminating Oysters

Researchers at the University of New Hampshire have discovered a new method to detect a bacterium that has contaminated New England oyster beds and sickened consumers who ate the contaminated shellfish. The new detection method is a significant advance in efforts to identify shellfish harboring disease-carrying strains of Vibrio parahaemolyticus.

Arctic Beetles May Be Ideal Marker of Climate Change

Researchers need to find ways to measure how the changes in climate are affecting biodiversity. One of the best places to look may be down at our feet, at beetles. That`s because, as a McGill research team discovered after doing the first large-scale survey of Arctic beetles, these six-legged critters are not only abundant in number but also diverse in feeding habits and what they eat is closely linked to the latitude in which they are found.

Calculating How the Pacific Was Settled

Canoe300dpi.jpg

Using statistics that describe how an infectious disease spreads, a University of Utah anthropologist analyzed different theories of how people first settled islands of the vast Pacific between 3,500 and 900 years ago. Adrian Bell found the two most likely strategies were to travel mostly against prevailing winds and seek easily seen islands, not necessarily the nearest islands.

Happily Ever After: Scientists Arrange Protein-Nanoparticle Marriage

protein_nanoparticle.jpg

University at Buffalo researchers have discovered a way to easily and effectively fasten proteins to nanoparticles – essentially an arranged marriage – by simply mixing them together. The biotechnology, described April 20 online in the journal Nature Chemistry, is in its infancy. But it already has shown promise for developing an HIV vaccine and as a way to target cancer cells.
