FLAGSTAFF, Ariz. – More than 400 years after its discovery by Galileo, the innermost large moon of Jupiter – Io – can finally rest on its geologic laurels. A group of scientists led by Dr. David A. Williams of Arizona State University has produced the first global geologic map of the Jovian satellite. The map, which was published by the U. S. Geological Survey, technically illustrates the geologic character of some of the most unique and active volcanoes ever documented in the solar system.

Since its discovery in January 1610, Io has been the focus of repeated observation, first by Earth-based telescopes, and later by fly-by and orbiting spacecraft. These studies depict an otherworldly celestial body whose gravitational relationships with Jupiter and sister moons Europa and Ganymede cause massive, rapid flexing of its surface and interior. This flexing generates tremendous heat in Io’s interior, which is relieved through surface volcanism, resulting in 25 times more volcanic activity than occurs here on Earth. (more…)

Mesquite Trees Displacing Southwestern Grasslands

Mesquite trees and woody shrubs are better adapted than grasslands to a Southwestern climate predicted to shift toward higher temperatures and greater variability in rainfall, UA ecologists have discovered.

As the desert Southwest becomes hotter and drier, semi-arid grasslands are slowly being replaced by a landscape dominated by mesquite trees, such as Prosopis velutina, and other woody shrubs, a team of University of Arizona researchers has found.

In a “leaf-to-landscape” approach, the team combined physiological experiments on individual plants and measurements across entire ecosystems to quantify how well grasslands, compared to mesquite trees and woody shrubs, cope with heat and water stress across seasonal precipitation periods. (more…)

Donating part of his liver and a kidney to two different recipients was not enough for Harry Kiernan. The Vietnam veteran and firefighter is now taking his efforts to raise awareness about organ donation many steps further by walking across the United States.

Kiernan’s 3,300-mile journey began on March 19 at Yale-New Haven Hospital, where a kick off ceremony for “Walk of 2012,” took place under the Donate Life flag near the hospital’s entrance. (more…)

EAST LANSING, Mich. — Having a triple-threat combination of protective software on your computer greatly reduces your chances of identity theft, according to a study led by a Michigan State University criminologist.

In a survey of more than 600 people, the researchers found that computer users who were running antivirus, anti-adware and anti-spyware software were 50 percent less likely to have their credit card information stolen.

The study appears in the research journal Deviant Behavior. (more…)

Milkweed Loss Hurts Monarchs

*Loss of milkweed in Midwestern farm fields harms butterflies, a study shows*

If you’re a gardener, milkweed may not be at the top of your list.

But if you love Minnesota’s state insect—the monarch butterfly—maybe it should be.

Monarchs lay their eggs on milkweed, but the plant is disappearing from what used to be a prime reservoir: Midwestern farm fields. A new study by University of Minnesota monarch expert Karen Oberhauser and her Iowa State colleague John Pleasants ties a decade-long decline in monarch populations to the loss of milkweed from the corn and soybean fields that blanket the region.

Exposed To Phthalates as Fetuses, Female Mice Have Altered Reproductive Lives

Many environmental and public health officials are concerned about the potential health effects of phthalates, which are common chemicals used to make plastics softer and more pliable. In the first study to examine what effect in utero doses of phthalates have on the reproductive system of mice, Brown University toxicologists found that extremely high doses were associated with significant changes, such as a shortened reproductive lifespan and abnormal cell growth in mammary glands.

PROVIDENCE, R.I. [Brown University] — Female mouse fetuses exposed to very high doses of a common industrial chemical that makes plastics more pliable develop significant reproductive alterations and precancerous lesions as they grow up, according to a new toxicology study conducted at Brown University.
