People often Talk About Politics on Blogs Geared Toward Other Topics

ANN ARBOR, Mich.— A full 25 percent of blog posts about politics occur on sites that are primarily about something else, according to a new study by researchers at the University of Michigan School of Information. And when authors post about politics, their readers reply and engage with the political content of the posts.

The researchers say they have uncovered a significant repository of political discourse that is largely being ignored. They will present their findings July 19 at the International Conference on Weblogs and Social Media in Barcelona. (more…)

Omega-3 Reduces Anxiety and Inflammation in Healthy Students

COLUMBUS, Ohio – A new study gauging the impact of consuming more fish oil showed a marked reduction both in inflammation and, surprisingly, in anxiety among a cohort of healthy young people.

The findings suggest that if young participants can get such improvements from specific dietary supplements, then the elderly and people at high risk for certain diseases might benefit even more. (more…)

Rising Oceans – Too Late to Turn the Tide?

*Melting ice sheets contributed much more to rising sea levels than thermal expansion of warming ocean waters during the Last Interglacial Period, a UA-led team of researchers has found. The results further suggest that ocean levels continue to rise long after warming of the atmosphere levels off.*

Thermal expansion of seawater contributed only slightly to rising sea levels compared to melting ice sheets during the Last Interglacial Period, a University of Arizona-led team of researchers has found.

The study combined paleoclimate records with computer simulations of atmosphere-ocean interactions and the team’s co-authored paper is accepted for publication in Geophysical Research Letters. (more…)

New Genetic Clues for Schizophrenia

De novo mutations – genetic errors that are present in patients but not in their parents – are more frequent in schizophrenic patients than in normal individuals, according to an international group of scientists led by Dr. Guy A. Rouleau of the University of Montreal and CHU Sainte-Justine Hospital. The discovery, published today in Nature Genetics, may enable researchers to define how the disease results from these mutations and eventually develop new treatments for it.

EAST LANSING, Mich. — Browning shoots and needles, twisting and stunted shoots – especially near the tops of evergreen trees and shrubs – are signs that plants may have injuries associated with the herbicide Imprelis, according to a Michigan State University researcher. (more…)

Is Meditation the Push-up for the Brain?

*Study shows practice may have potential to change brain’s physical structure*

Two years ago, researchers at UCLA found that specific regions in the brains of long-term meditators were larger and had more gray matter than the brains of individuals in a control group. This suggested that meditation may indeed be good for all of us since, alas, our brains shrink naturally with age.

Now, a follow-up study suggests that people who meditate also have stronger connections between brain regions and show less age-related brain atrophy. Having stronger connections influences the ability to rapidly relay electrical signals in the brain. And significantly, these effects are evident throughout the entire brain, not just in specific areas. (more…)

Max Webster, an undergraduate who founded and directs Climate Voices, a Yale-based NGO working to publicize the human rights impacts of climate change, recently attended the U.N. Climate Change Conference in Bonn, Germany. He shared his experiences, frustrations and insights about the meeting and his own mission with the Yale Daily Bulletin.

Bonn, Germany is not a typical tourist destination. Unless you are paying a visit to the birthplace of Beethoven, you are likely to be there only to attend a meeting of one of the 17 United Nations’ institutions housed in the city’s official U.N. campus. (more…)

*Long-term study shows students must know about numbers at beginning of first grade*

COLUMBIA, Mo. – Psychologists at the University of Missouri have identified the beginning of first grade math skills that teachers and parents should target to effectively improve children’s later math learning.

A long-term psychology study indicates that beginning first graders that understand numbers, the quantities those numbers represent, and low-level arithmetic will have better success in learning mathematics through the end of fifth grade, and other studies suggest throughout the rest of their lives.
