AMHERST, Mass. – Though it seems like an oxymoron, Arctic hurricanes happen, complete with a central “eye,” extreme low barometric pressure and towering 30-foot waves that can sink small ships and coat metal platforms with thick ice, threatening oil and gas exploration. Now climate scientists at the University of Massachusetts Amherst and in England report the first conclusive evidence that Arctic hurricanes, also known as polar lows, play a significant role in driving ocean water circulation and climate.
Results point to potentially cooler conditions in Europe and North America in the 21st century than other models predict. (more…)
A surprising number of microorganisms – more than 100 times more kinds than reported just four months ago – are leaping the biggest gap on the planet. Hitching rides in the upper troposphere, they’re making their way from Asia across the Pacific Ocean and landing in North America.
For the first time researchers have been able to gather enough biomass in the form of DNA to apply molecular methods to samples from two large dust plumes originating in Asia in the spring of 2011. The scientists detected more than 2,100 unique species compared to only 18 found in the very same plumes using traditional methods of culturing, results they published in July. (more…)
The asteroid collision widely thought to have killed the dinosaurs also led to extreme devastation among snake and lizard species, according to new research — including the extinction of a newly identified lizard Yale and Harvard scientists have named Obamadon gracilis.
“The asteroid event is typically thought of as affecting the dinosaurs primarily,” said Nicholas R. Longrich, a postdoctoral associate with Yale’s Department of Geology and Geophysics and lead author of the study. “But it basically cut this broad swath across the entire ecosystem, taking out everything. Snakes and lizards were hit extremely hard.” (more…)
PASADENA, Calif. – A new analysis led by NASA’s Jet Propulsion Laboratory, Pasadena, Calif., has estimated how much the growth of plants worldwide is limited by the amount of nutrients available in their soil. The maps produced from the research will be particularly useful in evaluating how much carbon dioxide Earth’s ecosystems may be able to soak up as greenhouse gas levels increase.
A research team led by JPL research scientist Josh Fisher used 19 years of data from NASA, National Oceanic and Atmospheric Administration and international satellites to assess the maximum possible growth of vegetation all over the world based upon available water and light conditions. The scientists then cross-compared that potential maximum with observed vegetation productivity as measured by satellites. This is the first time such an analysis has been conducted.(more…)
Students use tornado-chasing technology to research rain’s impact on stream
COLUMBIA, Mo. – With advances in meteorology technology, predicting storms is becoming easier than in the past. While most meteorology students learn about these new technologies in the classroom and don’t get a chance to use sophisticated equipment until they are on the job, a group of University of Missouri students were able to test a mobile weather tracking device, Doppler on Wheels (DOW), made famous by shows such as Discovery Channel’s Storm Chasers.
The DOW visiting MU is one of a fleet of radar trucks maintained by the Center for Severe Storm Research. Each radar truck is mounted with a Doppler weather radar dish. The fleet also consists of a support vehicle and three trucks that deploy instruments to track weather patterns in tornadoes and hurricanes. One of the radar trucks was brought to MU so that students could learn about the technology first-hand. (more…)
Only 1 in 5 firms excels at supporting new regulation and responding rapidly to client demands
Leading firms are rethinking their operations, forming external partnerships
NEW YORK, N.Y. – 21 Sep 2012: A new report released by IBM in collaboration with Broadridge Financial Solutions, Inc. reveals that increasing regulatory pressures and shifting customer demands are forcing financial markets firms to transform how they operate. Forward-thinking firms are breaking away from the industry’s long-held “not invented here” approach to managing operations to create a more open, agile and customer-focused model that expands the traditional boundaries of collaboration with external partners.
In a survey of 133 senior business executives and top IT decision makers from large and small firms located in the world’s trading centers – the United States, United Kingdom, Singapore and Hong Kong – 77 percent cite regulatory requirements and 59 percent point to more demanding customers as the top external market drivers triggering changes in their operating models. Only 22 percent of the firms currently excel at meeting both. (more…)
Michael Dula recently began his appointment as chief technology officer for the Yale University Library, which is one of the largest university libraries in North America. In this newly created role, he will develop a technology strategy for the University’s 18 different libraries, which house over 12.5 million volumes.
Prior to coming to Yale, Dula worked at Pepperdine University, where he began as a consultant. In 2006, he accepted a full-time position at Pepperdine as director of digital initiatives for the university’s libraries. In addition to managing central library technology systems, he was actively engaged in implementing new tools for research and learning, including digital content collections, scholarly publishing, podcasting, and social computing models.

James Watson, a UA anthropologist, has published chapters describing how long-term environmental trends encourage stable adaptations within local environments.
Human/environment interactions have a history as long as the existence of our species on the planet.
Hominid ancestors began polluting their environment nearly 700,000 years ago with the control of fire, and humans have not looked back since.
The modern phenomenon of global warming is very likely the direct result of human pollution and destruction of the environment, said James Watson, a University of Arizona assistant professor in the School of Anthropology. (more…)
