It’s possible for volcanoes to have a short-term impact on the climate – including global temperature cooling – due to the gases they inject high into the upper atmosphere. But Mount Ruang’s influence on the climate will likely be minimal, according to Greg Huey, professor and chair of the School of Earth and Atmospheric Sciences. And the day-to-day weather conditions near Mount Ruang in Indonesia – things like temperature, clouds and rain – probably won’t be influenced by the volcano for long, Huey told CNN. “The ash itself is short-lived in the atmosphere because it’s heavy, it’s big and it tends to settle out quickly,” Huey told CNN. It’s the gases that are able to reach much higher in the atmosphere. (This story also appeared at WRAL.)

"A dog is a man's best friend," the old saying goes. Can the same soon be said of robot dogs? This summer, a group of scientists including alumna Feifei Qian (M.S. PHYS 2011, Ph.D. ECE 2015) and School of Earth and Atmospheric Sciences assistant professor Frances Rivera-Hernández, will travel to Oregon's snow-capped Mt. Hood to train a dog-shaped robot named Spirit how to walk. The slopes of Mt. Hood are strewn with volcanic rocks and sprinkled with glaciers, a rugged environment that researchers think resembles the moon — which Spirit is being prepared to eventually explore.

In a new study, published in GEN Biotechnology titled, “Changes in Gene Network Interactions in Breast Cancer Onset and Development,” researchers from the School of Biological Sciences and the Integrated Cancer Research Center (Zainab Arshad, Stephen N. Housley, Kara Keun Lee, and John F. McDonald) have identified differential gene-network changes characteristic of the three most prevalent molecular subtypes of breast cancer, Luminal A, Luminal B, and the highly metastatic Basal-like subtype. In contrast to previous studies, the authors expanded their analysis beyond genes differentially expressed between normal and cancer samples, as differential gene expression may not be a prerequisite for changes in gene-gene interactions.
