*Climate models predict stable wind energy patterns over the United States*
Rising global temperatures will not significantly affect wind energy production in the United States concludes a new study published this week in the Proceedings of the National Academy of Sciences Early Edition.
But warmer temperatures could make wind energy somewhat more plentiful say two Indiana University (IU) Bloomington scientists funded by the National Science Foundation (NSF). (more…)
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…)
*Fareologists offer insight for how travelers can save money during a tough travel season.*
REDMOND, Wash. — May 4, 2011 — The Fareologists at Bing Travel (https://www.bing.com/travel) today issued their forecast for the 2011 summer travel season, predicting airfare and hotel costs will continue to swell. Compared with last year, airfare is expected to be up 15 percent, with tickets averaging $561, up from $485 last summer. Summer hotel costs will rise by more than 7 percent, with average costs at $242, versus $227 last year.
“Airlines are making deeper cuts in capacity, and surcharges are burgeoning,” said Krista Pappas, global travel industry director at Bing. “With oil prices on the rise, travelers can expect fares to continue to climb to offset fuel costs. Airlines also will continue to charge fees for their services, such as more leg room, premium boarding, baggage fees, Wi-Fi, food and entertainment.” (more…)
GAINESVILLE, Fla. — When a movie character says, “It’s too quiet,” that’s usually a sign something bad may happen.
Now, University of Florida researchers have discovered that when variations of a certain protein in our cells are too quiet, it may add to the risk that someone will develop lung cancer. When scientists restored the protein to its normal, active self, its cancer-inhibiting properties reappeared. (more…)
WASHINGTON — The West Coast of North America has caught a break that has left sea level in the eastern North Pacific Ocean steady during the last few decades, but there is evidence that a change in wind patterns may be occurring that could cause coastal sea-level rise to accelerate beginning this decade.(more…)
*Facebook.com Now Accounts for Nearly 1 in 3 Online Display Ads in U.S.*
RESTON, VA, May 4, 2011 – comScore, Inc., a leader in measuring the digital world, today released an overview of the U.S. online display advertising market for Q1 2011 based on data from comScore Ad Metrix, indicating that nearly 1.11 trillion display ads were delivered to U.S. Internet users during the quarter. Facebook accounted for 346 billion impressions, nearly double the number it delivered in Q1 2010, and accounting for nearly one third of all display ad impressions delivered. (more…)
Thanks in part to studies that follow subjects for a long time, psychologists are learning more about differences between people. In a new article published in Current Directions in Psychological Science, a journal of the Association for Psychological Science, the author describes how psychologists can use their data to learn about the different ways that people’s minds work.
Most psychology research is done by asking a big group of people the same questions at the same time. “So we might get a bunch of Psych 101 undergrads, administer a survey, ask about how much they use alcohol and what their mood is, and just look and see, is there a relationship between those two variables,” says Daniel J. Bauer of the University of North Carolina at Chapel Hill, the author of the article. (more…)
ANN ARBOR, Mich.—Electrical engineers at the University of Michigan have built a device that can harness energy from vibrations and convert it to electricity with five to 10 times greater efficiency and power than other devices in its class. And it’s smaller than a penny.
“In a tiny amount of space, we’ve been able to make a device that generates more power for a given input than anything else out there on the market,” said Khalil Najafi, one of the system’s developers and chair of Electrical and Computer Engineering. (more…)
