New Study to Test Unusual Hypothesis on Beta Brainwaves

Beta oscillations are tightly linked to Parkinson’s disease and the ability to process sensory information, such as touch. Two neuroscientists have brought their collaboration to Brown University and won funding from the National Science Foundation to see if they can finally provide a definitive, if unorthodox, explanation for beta brainwaves.

Before she could seek to convince the world that her computer model of a key brain circuit explains a fundamental, 80-year-old mystery of neuroscience with potential relevance to Parkinson’s disease, Stephanie Jones sought to convince Christopher Moore. The new Brown neuroscience professors are now close collaborators, but when they first started talking about the beta oscillations of the cortex, Moore thought Jones was plain wrong, if not a bit nuts.

Study Debunks Stereotype That Men Think About Sex All Day Long

Health

COLUMBUS, Ohio – Men may think about sex more often than women do, but a new study suggests that men also think about other biological needs, such as eating and sleep, more frequently than women do, as well. (more…)

Powerful Mathematical Model Greatly Improves Predictions for Species Facing Climate Change

Environment, Nature, Science

UCLA life scientists and colleagues have produced the most comprehensive mathematical model ever devised to track the health of populations exposed to environmental change.

The research, federally funded by the National Science Foundation, is published Dec. 2 in the journal Science.

The team’s groundbreaking integral projection model, or IPM, unites various sub-disciplines of population biology, including population ecology, quantitative genetics, population genetics, and life-span and offspring information, allowing researchers to link many different data sources simultaneously. Scientists can now change just a single variable, like temperature, and see how that affects many factors for a population. (more…)

Moral Dilemma: Would You Kill One Person to Save Five?

Science

EAST LANSING, Mich. — Imagine a runaway boxcar heading toward five people who can’t escape its path. Now imagine you had the power to reroute the boxcar onto different tracks with only one person along that route.

Would you do it? (more…)

Yale-led Team Finds CO2 Levels Plunged as Antarctica Froze

Environment

A Yale University-led research team has found evidence that carbon dioxide levels in Earth’s atmosphere plunged prior to and during the initial icing of Antarctica, about 34 million years ago. The new findings provide further evidence of atmospheric carbon dioxide’s role as a major trigger of global climate change.

“CO2 is tracking global cooling at that time,” said Yale geochemist Mark Pagani, lead author of a paper published online Dec. 1 in the journal Science. “It’s important to demonstrate that there are obvious linkages between CO2 and climate change. It’s one more piece of evidence that CO2 is a primary lever on climate.” (more…)

Israeli Public Supports Middle East Nuclear Free Zone: UMD Poll

Politics

COLLEGE PARK, Md. — Nearly two-thirds of Israeli Jews, 64 percent, favor establishing a nuclear free zone in the Middle East – even when it was spelled out that this would mean both Israel and Iran would have to forego nuclear weapons – finds a new University of Maryland poll. The research is a joint project of the Anwar Sadat Chair at the University of Maryland and the Program on International Policy Attitudes (PIPA). (more…)

Serendipitous News Reading Online is Gaining Prominence, MU Study Shows

Media

*Media should place news links on different sites to take advantage of this phenomenon*

COLUMBIA, Mo. –Traditional media, such as newspapers and television news, require readers and viewers to intentionally seek out news by picking up a newspaper or turning on the television. The Internet and new technologies now are changing the way readers consume online news. New research from the University of Missouri shows that Internet users often do not make the conscious decision to read news online, but they come across news when they are searching for other information or doing non-news related activities online, such as shopping or visiting social networking sites.
