Electrical Images Show Upward Flow of Fluids to Magma Chamber

By measuring how fast Earth conducts electricity and seismic waves, a University of Utah researcher and colleagues made a detailed picture of Mount Rainier’s deep volcanic plumbing and partly molten rock that will erupt again someday.

“This is the most direct image yet capturing the melting process that feeds magma into a crustal reservoir that eventually is tapped for eruptions,” says geophysicist Phil Wannamaker, of the university’s Energy & Geoscience Institute and Department of Civil and Environmental Engineering. “But it does not provide any information on the timing of future eruptions from Mount Rainier or other Cascade Range volcanoes.” (more…)

Short lives, violent deaths: Two CT-scanned Siberian mammoth calves yield trove of insights

ANN ARBOR — CT scans of two newborn woolly mammoths recovered from the Siberian Arctic are revealing previously inaccessible details about the early development of prehistoric pachyderms. In addition, the X-ray images show that both creatures died from suffocation after inhaling mud.

Lyuba and Khroma, who died at ages 1 and 2 months, respectively, are the most complete and best-preserved baby mammoth specimens ever found. Lyuba’s full-body CT scan, which used an industrial scanner at a Ford testing facility in Michigan, was the first of its kind for any mammoth. (more…)

A study from North Carolina State University finds that data from CT scans can be incorporated into a growing forensic database to help determine the ancestry and sex of unidentified remains. The finding may also have clinical applications for craniofacial surgeons. (more…)

One-Way Air Flow May Be 270 Million Years Old

Air flows mostly in a one-way loop through the lungs of monitor lizards – a breathing method shared by birds, alligators and presumably dinosaurs, according to a new University of Utah study.

The findings – published online Wednesday, Dec. 11 in the journal Nature – raise the possibility this breathing pattern originated 270 million years ago, about 20 million years earlier than previously believed and 100 million years before the first birds. Why remains a mystery. (more…)

Seeing in the Dark

New research sheds light on how porpoises hear in one of the world’s busiest rivers

The Yangtze finless porpoise, which inhabits the high-traffic waters near the Three Gorges Dam in China, is highly endangered, with only about 1,000 animals alive today. Scientists from Woods Hole Oceanographic Institution (WHOI) and their Chinese colleagues are using medical technology to shed new light on this species’ critical sense of hearing in a waterway punctuated by constant shipping, dredging, and underwater construction.

“We want to understand how they may be impacted by noise,” said Aran Mooney, a biologist at the Woods Hole Oceanographic Institution (WHOI) and a lead author on the study published online this week in the Journal of Experimental Biology. (more…)

Minimally invasive surgery may benefit patients previously deemed hopeless

A new endoscopic surgical procedure has been shown to be safer and to result in better outcomes than the current standard medical treatment for patients who suffer strokes as a result of brain hemorrhages, UCLA neurosurgeons have announced.

The findings from their potentially groundbreaking, randomized, controlled phase 2 clinical trial, which was conducted at multiple medical centers, were presented last week at the International Stroke Conference in Honolulu. (more…)

The IBM 5 in 5 is based on market and societal trends as well as emerging technologies from IBM’s R&D labs around the world that can make these transformations possible. (more…)

CT Study of Early Humans Reveals Evolutionary Relationships

CT scans of fossil skull fragments may help researchers settle a long-standing debate about the evolution of Africa’s Australopithecus, a key ancestor of modern humans that died out some 1.4 million years ago.

The study, to be published in the Proceedings of the National Academy of Sciences, explains how CT scans shed new light on a classic evolutionary puzzle by providing crucial information about the internal anatomy of the face. (more…)
