Missouri S&T Geologist Named AAAS Fellow

WASHINGTON _ Dr. Francisca Oboh-Ikuenobe of Missouri University of Science and Technology has been named a fellow of the American Association for the Advancement of Science (AAAS) for her contributions to the advancement of palynology ─ the study of organic-walled microfossils such as pollen and spores ─ and her outstanding efforts in educating the next generation of Earth scientists.

Rise in Oxygen Levels Link to Ancient Explosion of Life, Researchers Find

A team of researchers, including a faculty member and postdoctoral fellow from Washington University in St. Louis, found that oxygen levels appear to increase at about the same time as a three-fold increase in biodiversity during the Ordovician Period, between 445 and 485 million years ago, according to a study published Nov. 20 in Nature Geoscience.

Save the Date: Acoustical Society of America Fall Meeting in New Orleans, Dec. 4-8

Acoustical waves and vibrations allow us to hear and experience the world with fuller sensory stimulation. Acoustics has applications that cover a broad spectrum of topics including anthropogenic noise in marine environments, the dangers of hospital noise, and auditory sensitivity after drinking. The Acoustical Society of America’s fall meeting this year will showcase the diversity of sound and its applications, held Dec. 4-8, 2017, in New Orleans, Louisiana.

A Popular Tool to Trace Earth’s Oxygen History Can Give False Positives

If someone cries "Eureka!" because it looks like oxygen appeared in Earth's ancient atmosphere long before the body of evidence indicated, consider this: If it was a chromium isotope system reading that caused the enthusiasm, it might need to be curbed.

UWM Geologists Uncover Antarctica’s Fossil Forests

fossil.forest2.jpg

Prehistoric polar forests were built for survival, but were not hardy enough to live in ultra-high concentrations of atmospheric carbon dioxide. A UWM geologist is studying the tree fossil record in Antarctica from a mass extinction 250 million years ago, looking for clues to how greenhouse gases affected plants -- then and now.
