COLUMBIA, Mo. – According to the Centers for Disease Control and Prevention, 1.7 million people suffer traumatic brain injuries each year. Stephanie Reid-Arndt, chair and assistant professor of health psychology in the University of Missouri School of Health Professions, has launched The Brain Injury Guide and Resources at https:// braininjuryeducation.com/ to provide a resource for people to understand traumatic brain injuries.

“Brain injuries aren’t visible like other injuries, and often, people with brain injuries can be misunderstood,” Reid-Arndt said. “Direct results of a traumatic brain injury (TBI) include cognitive difficulties, changes in behavior or difficulty managing anger that are direct results of the brain injuries. Unfortunately, these symptoms are often misconstrued as willfully uncooperative behavior.” (more…)

Where the Earth’s Heat Comes From

Berkeley Lab scientists join their KamLAND colleagues to measure the radioactive sources of Earth’s heat flow

What spreads the sea floors and moves the continents? What melts iron in the outer core and enables the Earth’s magnetic field? Heat. Geologists have used temperature measurements from more than 20,000 boreholes around the world to estimate that some 44 terawatts (44 trillion watts) of heat continually flow from Earth’s interior into space. Where does it come from? (more…)

Making Blood-Sucking Deadly for Mosquitoes

*Inhibiting a molecular process cells use to direct proteins to their proper destinations causes more than 90 percent of affected mosquitoes to die within 48 hours of blood feeding, a UA team of biochemists found.*

Mosquitoes die soon after a blood meal if certain protein components are experimentally disrupted, a team of biochemists at the University of Arizona has discovered.

The approach could be used as an additional strategy in the worldwide effort to curb mosquito-borne diseases like dengue fever, yellow fever and malaria. (more…)

PASADENA, Calif. — NASA’s Dawn spacecraft on Saturday became the first probe ever to enter orbit around an object in the main asteroid belt between Mars and Jupiter.

Dawn will study the asteroid, named Vesta, for a year before departing for a second destination, a dwarf planet named Ceres, in July 2012. Observations will provide unprecedented data to help scientists understand the earliest chapter of our solar system. The data also will help pave the way for future human space missions. (more…)

Symbiogenics — a New Strategy for Reducing Climate Impacts on Plants

Seattle – Rice – which provides nearly half the daily calories for the world’s population – could become adapted to climate change and some catastrophic events by colonizing its seeds or plants with the spores of tiny naturally occurring fungi, just-published U.S. Geological Survey-led research shows.

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…)
