Forensic anthropology researchers at North Carolina State University have developed a technique that can provide an approximate age for juveniles and young people based on an X-ray of the frontal sinus region of the skull. The technique can be used to help identify human remains in forensic cases, as well as to determine age ranges in archaeological research or for living people for whom no records are available.

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…)
