Deforestation, considered by scientists to contribute significantly to global warming, has been shown by a Yale-led team to actually cool the local climate in northern latitudes, according to a paper published Nov. 17 in Nature.

“If you cut trees in the boreal region, north of 45 degrees latitude, you have a net cooling effect,” says Xuhui Lee, the study’s principal investigator and professor of meteorology at the Yale School of Forestry & Environmental Studies. “You release carbon into the atmosphere by cutting down trees, but you increase the albedo effect — the reflection of sunlight.” (more…)

MOUNTAIN VIEW, Calif. – Sean Suchter’s last name is a misspelling of the German word for searcher, which has to be one of the greater aptronyms in the technology industry.

Suchter heads up Bing’s social search team on Microsoft’s Silicon Valley Campus, where he relishes his job as a frontiersmen in the field of search, particularly social search. (more…)

GAINESVILLE, Fla. — Florida has the world’s worst invasive amphibian and reptile problem, and a new 20-year study led by a University of Florida researcher verifies the pet trade as the No. 1 cause of the species’ introductions.

From 1863 through 2010, 137 non-native amphibian and reptile species were introduced to Florida, with about 25 percent of those traced to one animal importer. The findings appear online today in Zootaxa. (more…)

*Outstanding educators using technology are recognized for their contribution and impact in teaching.*

REDMOND, Wash. — Aug. 1, 2011 — Microsoft Corp. today announced 11 educators from Alabama, Alaska, California, Florida, Michigan, Pennsylvania, South Carolina and Washington who have been selected as winners of the 2011 U.S. Innovative Education Forum (IEF). The IEF is an event recognizing innovative teachers and school leaders who creatively and effectively use technology in their curriculum to help improve the way kids learn while increasing student success. Out of the thousands that applied, 100 educators from 25 states were selected for a spot to compete on Microsoft’s corporate campus in Redmond. IEF participants also voted on their peers in the Educator’s Choice category and selected a winning project. The winning educators will represent the U.S. and advance to compete against educators from around the world at the Partners in Learning Global Forum, Nov. 6–11, 2011 in Washington, D.C. (more…)

Radar for Mars Gets Flight Tests at NASA Dryden

Southern California’s high desert has been a stand-in for Mars for NASA technology testing many times over the years. And so it is again, in a series of flights by an F/A-18 aircraft to test the landing radar for NASA’s Mars Science Laboratory mission.

The flight profile is designed to have the F/A-18 climb to 40,000 feet (about 12,000 meters). From there, it makes a series of subsonic, stair-step dives at angles of 40 to 90 degrees to simulate what the Mars radar will see while the spacecraft is on a parachute descending through the Martian atmosphere. The F/A-18 pulls out of each dive at 5,000 feet (about 1,500 meters. Data collected by these flights will be used to finesse the Mars landing radar software, to help ensure that it is calibrated as accurately as possible. (more…)

UF: Florida Population Soars in Century’s First Decade, But Rate is Slowing

GAINESVILLE, Fla. — Florida was again one of the country’s leaders in population growth in the last decade, but the growth rates over the past few years have been among the lowest in the state’s history, according to a new study by the University of Florida.

Florida’s permanent resident population increased by more than 2.8 million between 2000 and 2010 — an increase of 17.6 percent to 18,801,310. That mark was the third-largest numeric increase and the eighth-largest percentage increase in the country. However, the growth rate lagged behind previous periods for the state, and projections are the growth rate will steadily decline through 2040. (more…)

Dawn Reaches Milestone Approaching Asteroid Vesta

PASADENA, Calif. — NASA’s Dawn spacecraft has reached its official approach phase to the asteroid Vesta and will begin using cameras for the first time to aid navigation for an expected July 16 orbital encounter. The large asteroid is known as a protoplanet — a celestial body that almost formed into a planet.

At the start of this three-month final approach to this massive body in the asteroid belt, Dawn is 1.21 million kilometers (752,000 miles) from Vesta, or about three times the distance between Earth and the moon. During the approach phase, the spacecraft’s main activity will be thrusting with a special, hyper-efficient ion engine that uses electricity to ionize and accelerate xenon. The 12-inch-wide ion thrusters provide less thrust than conventional engines, but will provide propulsion for years during the mission and provide far greater capability to change velocity. (more…)

Fossil Bird Study Describes Ripple Effect of Extinction in Animal Kingdom

GAINESVILLE, Fla. — A University of Florida study demonstrates extinction’s ripple effect through the animal kingdom, including how the demise of large mammals 20,000 years ago led to the disappearance of one species of cowbird.

The study shows the trickle-down effect the loss of large mammals has on other species, and researchers say it is a lesson from the past that should be remembered when making conservation, game and land-use decisions today. (more…)
