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…)

Neurons that Control Overeating also Drive Appetite for Cocaine

Researchers at Yale School of Medicine have zeroed in on a set of neurons in the part of the brain that controls hunger, and found that these neurons are not only associated with overeating, but also linked to non-food associated behaviors, like novelty-seeking and drug addiction.

Published in the June 24 online issue of Nature Neuroscience, the study was led by Marcelo O. Dietrich, postdoctoral associate, and Tamas L. Horvath, the Jean and David W. Wallace Professor of Biomedical Research and chair of comparative medicine at Yale School of Medicine.

In attempts to develop treatments for metabolic disorders such as obesity and diabetes, researchers have paid increasing attention to the brain’s reward circuits located in the midbrain, with the notion that in these patients, food may become a type of “drug of abuse” similar to cocaine. Dietrich notes, however, that this study flips the common wisdom on its head. (more…)

Water in a Changing World

Experimental watershed provides new insights, rich educational experience

Six years and about 4,000 water samples later, an outdoor experimental watershed laboratory established by University of Delaware faculty members Shreeram Inamdar and Delphis Levia at Fair Hill, Md., is now producing valuable data and novel insights into how water and chemicals move through the forest canopy, soils and watersheds, and how future climate change may impact or alter such responses.

Inamdar, associate professor in the Department of Plant and Soil Sciences, has investigated the role of soils, streams, and watersheds in leaching water and nutrients, while Levia, professor in the Department of Geography, has studied the interactions of atmosphere and the forest canopy in leaching water and nutrients. Together, they have provided a complete picture of watershed hydrology and biogeochemistry. (more…)

Satiric News Decreases Bias Against Arab-Americans and Al Jazeera

ANN ARBOR, Mich.— Satiric news coverage—a format seen on programs such as “The Daily Show with Jon Stewart”—decreases Arab American prejudice and bias against Al Jazeera English.

A new University of Michigan study finds that Americans can change their views about Al Jazeera English, a global news network, depending on how it is covered by other media.

AJE has not been welcomed in the United States, in part, because many people associate it with Al Qaeda and other American adversaries. Many Americans presume the network is biased and driven by an anti-American agenda. (more…)

Lariats: How RNA Splicing Decisions are Made

Lariats are discarded byproducts of RNA splicing, the process by which genetic instructions for making proteins are assembled. A new study has found hundreds more lariats than ever before, yielding new information about how splicing occurs and how it can lead to disease

PROVIDENCE, R.I. [Brown University] — Tiny, transient loops of genetic material, detected and studied by the hundreds for the first time at Brown University, are providing new insights into how the body transcribes DNA and splices (or missplices) those transcripts into the instructions needed for making proteins. (more…)
