Unusually warm temperatures can wreak havoc on the world's climate, but these warming periods also have an upside that may help researchers better understand global climate change. In a study published in "Science" magazine, University of New Hampshire scientists describe how a warm anomaly helps temporarily brake the ongoing rise in atmospheric CO2 attributed to human activity.
Dave A. Berque, DePauw University associate professor of computer science, and his students have developed an electronic blackboard that enables the professor to write lecture notes on a laser board on the wall, and the professor's handwritten lecture notes are automatically transferred to PCs at the students' desks. Students can use a light pen to annotate the notes on their PC screens and then save the notes for future review and study.
Microorganisms require a different way of thinking in terms of diversity. Cultivated soils, for example, often have more microbial diversity than do native grassland soils. Whereas in undisturbed soil, microbes tend to develop pockets and communities, in tilled soils they become evenly distributed. When we till soil, we think we're doing the right thing, says Kennedy. But what's happening is the community is going berserk.
Minority psychologists in academic settings are generally less satisfied than their White counterparts. That's according to a new study co-authored by John D. Dovidio, professor of psychology at Colgate University which examines how perceptions of racial distinctivess relate to job satisfaction of White and ethnic/racial minority American Psychological Association members working in psychology departments in academia.
