COLLEGE PARK, Md. — Infidelity in a relationship can be costly—personally, financially and socially—yet it remains an exceedingly common occurrence. New research led by the University of Maryland Department of Psychology provides a comprehensive list of the main reasons people cheat, and questions traditional wisdom about what infidelity means in a relationship.

When Washington legalized recreational marijuana in 2012, a primary concern was how to ensure it was kept out of the reach of children. (more…)
What do Velcro, Tang, penicillin, the structure of DNA and the World Wide Web have in common?
They all involved serendipitous discoveries—chance discoveries made by alert, curious scientists who were looking for other things when they happened across a fortuitous finding. Rather than ignoring their accidental discoveries, these curious, open-minded scientists harnessed their luck. “Chance favors only the prepared mind,” as Louis Pasteur put it. (more…)
Oceanography graduate student lands scholarship supporting wetland research
Growing up along Lake Pontchartrain in New Orleans, Brandon Boyd spent a lot of time hunting for waterfowl and fishing for speckled trout in marshes and swamps. There, wetlands are a way of life.
“Ever since I was in high school, I knew I really wanted to do something to help protect wetlands,” said Boyd, a graduate student in oceanography in the School of Marine Science and Policy within the University of Delaware’s College of Earth, Ocean, and Environment. (more…)
UCLA researchers have used a brain-imaging tool and stroke risk assessment to identify signs of cognitive decline early on in individuals who don’t yet show symptoms of dementia.
The connection between stroke risk and cognitive decline has been well established by previous research. Individuals with higher stroke risk, as measured by factors like high blood pressure, have traditionally performed worse on tests of memory, attention and abstract reasoning. (more…)
Fear can play a role in influencing political attitudes on hot-button issues like immigration, according to new research co-authored by Brown political scientist Rose McDermott. The study, published in the American Journal of Political Science, shows that individuals who are genetically predisposed to fear tend to have more negative out-group opinions, which play out politically as support for policies like anti-immigration and segregation.
PROVIDENCE, R.I. [Brown University] — It’s no secret that fear is a mechanism often used in political campaigns to steer public opinion on hot-button issues like immigration and war. But not everyone is equally predisposed to be influenced by such a strategy, according to new research by Rose McDermott, professor of political science, and colleagues published in the American Journal of Political Science.

Washington, D.C. — Scientists have long speculated about why there is a large change in the strength of rocks that lie at the boundary between two layers immediately under Earth’s crust: the lithosphere and underlying asthenosphere. Understanding this boundary is central to our knowledge of plate tectonics and thus the formation and evolution of our planet as we know it today. A new technique for observing this transition, particularly in the portion of Earth’s mantle that lies beneath the Pacific Ocean basin, has led Carnegie and NASA Goddard scientist Nick Schmerr to new insight on the origins of the lithosphere and asthenosphere. His work is published March 23 in Science.
The lithosphere-asthenosphere boundary, or LAB, represents the transition from hot, convecting mantle asthenosphere to overlying cold and rigid lithosphere. The oceanic lithosphere thickens as it cools over time, and eventually sinks back into the mantle at Earth’s so-called subduction zones. (more…)
La Niña, “the diva of drought,” is peaking, increasing the odds that the Pacific Northwest will have more stormy weather this winter and spring, while the southwestern and southern United States will be dry.
Sea surface height data from NASA’s Jason-1 and -2 satellites show that the milder repeat of last year’s strong La Niña has recently intensified, as seen in the latest Jason-2 image of the Pacific Ocean, available at: https://sealevel.jpl.nasa.gov/images/ostm/20120108P1.jpg. (more…)
