MU Students Gain Experience with Advanced Weather Tracking Technology

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…)

Q&A: Libraries Turn New Page into Digital Age

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.

Humans Have Love-Hate Relationship With the Environment

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…)

Where Have All the Hummingbirds Gone?

Glacier lilies and broad-tailed hummingbirds out of sync

The glacier lily as it’s called, is a tall, willowy plant that graces mountain meadows throughout western North America. It flowers early in spring, when the first bumblebees and hummingbirds appear.

Or did.

The lily, a plant that grows best on subalpine slopes, is fast becoming a hothouse flower. In Earth’s warming temperatures, its first blooms appear some 17 days earlier than they did in the 1970s, scientists David Inouye and Amy McKinney of the University of Maryland and colleagues have found.

Statistical Analysis Projects Future Temperatures in North America

COLUMBUS, Ohio – For the first time, researchers have been able to combine different climate models using spatial statistics – to project future seasonal temperature changes in regions across North America.

They performed advanced statistical analysis on two different North American regional climate models and were able to estimate projections of temperature changes for the years 2041 to 2070, as well as the certainty of those projections.

The analysis, developed by statisticians at Ohio State University, examines groups of regional climate models, finds the commonalities between them, and determines how much weight each individual climate projection should get in a consensus climate estimate. (more…)

International Team Uncovers New Genes That Shape Brain Size, Intelligence

*UCLA-launched partnership identifies genes that boost or lessen risk of brain atrophy, mental illness, Alzheimer’s disease*

In the world’s largest brain study to date, a team of more than 200 scientists from 100 institutions worldwide collaborated to map the human genes that boost or sabotage the brain’s resistance to a variety of mental illnesses and Alzheimer’s disease.

Published April 15 in the advance online edition of the journal Nature Genetics, the study also uncovers new genes that may explain individual differences in brain size and intelligence. (more…)

Ocean Acidification Linked With Larval Oyster Failure in Hatcheries

*Increase in ocean acidification led to collapse of oyster seed production at Oregon hatchery*

Marine researchers have definitively linked the collapse of oyster seed production at a commercial oyster hatchery in Oregon to an increase in ocean acidification.

Larval growth at the hatchery declined to a level considered by the owners to be “non-economically viable.”

A study by the scientists found that increased seawater carbon dioxide (CO2) levels, resulting in more corrosive ocean water, inhibited the larval oysters from developing their shells and growing at a pace that would make commercial production cost-effective. (more…)

Rare Animal-Shaped Mounds Discovered in Peru by MU Anthropologist

*Anthropology Helps Us Understand the Past and Allows for a Deeper Understanding of the Future.*

COLUMBIA, Mo. — For more than a century and a half, scientists and tourists have visited massive animal-shaped mounds, such as Serpent Mound in Ohio, created by the indigenous people of North America. But few animal effigy mounds had been found in South America until University of Missouri anthropology professor emeritus Robert Benfer identified numerous earthen animals rising above the coastal plains of Peru, a region already renowned for the Nazca lines, the ruined city of Chan Chan, and other cultural treasures.

“The mounds will draw tourists, one day,” Benfer said. “Some of them are more than 4,000 years old. Compare that to the effigy mounds of North America, which date to between 400 and 1200 AD. The oldest Peruvian mounds were being built at the same time as the pyramids in Egypt.” (more…)
