VIENNNA, Austria – At the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) meeting, American researchers are unveiling a new tool for detecting illegal nuclear explosions: the Earth’s global positioning system (GPS).

Even underground nuclear tests leave their mark on the part of the upper atmosphere known as the ionosphere, the researchers discovered, when they examined GPS data recorded the same day as a North Korean nuclear test in 2009. Within minutes on that day, GPS stations in nearby countries registered a change in ionospheric electron density, as a bubble of disturbed particles spread out from the test site and across the planet.

The Winners of Mass Extinction: With Predators Gone, Prey Thrives

*Extinction of fishes 360 million years ago created natural ecology experiment*

In present-day ecology, the removal or addition of a predator in an ecosystem can produce dramatic changes in the population of prey species. For the first time, scientists have observed the same dynamics in the fossil record, thanks to a mass extinction that decimated ocean life 360 million years ago.

What was bad for fish was good for the fish’s food, according to a paper published online in Proceedings of the National Academy of Sciences. Researchers from the University of Chicago, West Virginia University and The Ohio State University found that the mass extinction known as the Hangenberg event produced a “natural experiment” in the fossil record, with results that mirror modern observations about predator-prey relationships.

Polluted Air Leads To Disease by Promoting Widespread Inflammation

COLUMBUS, Ohio – Chronic inhalation of polluted air appears to activate a protein that triggers the release of white blood cells, setting off events that lead to widespread inflammation, according to new research in an animal model.

This finding narrows the gap in researchers’ understanding of how prolonged exposure to pollution can increase the risk for cardiovascular problems and other diseases. (more…)

Time Running Out to Save Climate Record Held in Unique Eastern European Alps Glacier

COLUMBUS, Ohio – A preliminary look at an ice field atop the highest mountain in the eastern European Alps suggests that the glacier may hold records of ancient climate extending back as much as a thousand years.

Researchers warn, however, that the record may soon be lost as global warming takes its toll on these high-altitude sites, according to a new study in the Journal of Glaciology.

The glacier, Alto dell’Ortles, is the highest large ice body in the eastern Alps, reaching an altitude of 12,812 feet (3,905 meters) above sea level. It is small, though, measuring barely 0.4 square miles (1.04 square kilometers), and only 10 percent of that is likely to hold a good climate record, the researchers said. (more…)

Researchers Find Link Between Sugar, Diabetes and Aggression

COLUMBUS, Ohio — A spoonful of sugar may be enough to cool a hot temper, at least for a short time, according to new research.

A study found that people who drank a glass of lemonade sweetened with sugar acted less aggressively toward a stranger a few minutes later than did people who consumed lemonade with a sugar substitute.

Researchers believe it all has to do with the glucose, a simple sugar found in the bloodstream that provides energy for the brain. (more…)

Learning the Truth not Effective in Battling Rumors About NYC Mosque, Study Finds

COLUMBUS, Ohio – Evidence is no match against the belief in false rumors concerning the proposed Islamic cultural center and mosque near Ground Zero in New York City, a new study finds.

Researchers at Ohio State University found that fewer than one-third of people who had previously heard and believed one of the many rumors about the proposed center changed their minds after reading overwhelming evidence rejecting the rumor.

The false rumor that researchers used in the study was that Feisal Abdul Rauf, the Imam backing the proposed Islamic cultural center and mosque, is a terrorist sympathizer who has refused to condemn Islamic attacks on civilians. (more…)
