<description><![CDATA[Bigger risk of East Coast storms forecastSTATE COLLEGE, Pa., May 12 (UPI) -- A U.S. meteorological service is predicting a near average number of hurricanes this year but with an increased risk of storms along the U.S. East Coast.Although we are forecasting a total of 12 named storms in 2008, Â… a relatively high percentage of tropical storms are expected to make landfall and the major threat area is farther north than normal, said AccuWeather.com Chief Long-Range and Hurricane Forecaster Joe Bastardi. We believe at least 40 percent of named storms will cause tropical storm or hurricane conditions on the U.S. (eastern) coastline, which is about 1.6 times the norm.]]></description>

<title>Rainfall, rivers predict fish biodiversity</title>

<description><![CDATA[U.S. scientists say they have found water dynamics can play a pivotal role in the biodiversity of river networks.Princeton University Professor Ignacio RodrÃ­guez-Iturbe and colleagues say they've invented a method for turning simple data about rainfall and river networks into accurate assessments of fish biodiversity, allowing better prediction of the effects of climate change and the ecological impact of man-made structures like dams.The researchers say the mathematics behind the new method also can be used to model and predict the transmission of waterborne illnesses, as well as vegetation patterns on land adjacent to rivers.]]></description>

<title>New laser may help find Earthlike planets</title>
<link>http://it.moldova.org/stiri/eng/118604/</link>
<description><![CDATA[U.S. and German scientists say they've created an ultrafast laser that, among other things, might aid in the search for Earthlike planets.The researchers at the National Institute of Standards and Technology and the University of Konstanz in Germany said their laser offers a record combination of high speed, short pulses and high average power. The scientists say that type of laser, when used as a frequency comb -- an ultraprecise technique for measuring different colors of light -- could boost the sensitivity of astronomical tools searching for Earthlike planets by as much as 100 fold.The new laser emits 10 billion pulses per second, each lasting about 40 femtoseconds, or quadrillionths of a second, with an average power of 650 milliwatts, the scientists said.]]></description>

<title>Ponds take up carbon at high rate</title>
<link>http://it.moldova.org/stiri/eng/118603/</link>
<description><![CDATA[U.S. scientists say they've determined the Earth's ponds are capable of absorbing as much organic carbon as the world's oceans.The Iowa State University researchers led by limnologist (lake scientist) John Downing found constructed ponds and lakes located on farmland in the United States bury carbon at a much higher rate than expected -- as much as 20 to 50 times the rate at which trees trap carbon. In addition, ponds were found to take up carbon at a higher rate than larger lakes.Aquatic ecosystems play a disproportionately large role in the global carbon budget, Downing said.Despite being overlooked in the past, it's small bodies of water that are important because they take up carbon at a high rate and there are more of them than previously thought.]]></description>

<title>Study: MicroRNAs are essential for sight</title>
<link>http://it.moldova.org/stiri/eng/118586/</link>
<description><![CDATA[A team of U.S. and Italian scientists say they've determined microRNAs are essential for sight to develop.The researchers said retinas in newborn mice appear perfectly fine without any help from tiny bits of genetic material called microRNAs except the retinas don't work.Researchers at the University of Florida and the Italian National Research Council say their study is the first to focus on the effects of the absence of microRNAs in the mammalian eye. They said they found a gradual structural decline in retinas that lack microRNAs. That's in sharp contrast to the immediate devastation that occurs in limbs, lungs and other tissues that develop without microRNAs.]]></description>

<title>Silicon can have good effect on sunflowers</title>
<link>http://it.moldova.org/stiri/eng/118585/</link>
<description><![CDATA[U.S. horticulturists say they have determined silicon might have a beneficial effect on ornamental sunflowers if delivered in the correct concentration.Although silicon, a predominant element in mineral soil, isn't considered an essential nutrient for most plants, there has been limited evidence it might affect the aesthetic qualities of ornamental flowers.Oklahoma State University researchers Sophia Kamenidou and Todd Cavins examined the effects of silicon supplements on sunflowers grown in greenhouse environments.Cavins said the goal of the study was to determine the effects of silicon supplementation on the greenhouse-produced ornamental sunflower called Ring of Fire (Helianthus annuus L.).]]></description>

<title>Higher fuel prices may mean less pollution</title>
<link>http://it.moldova.org/stiri/eng/118581/</link>
<description><![CDATA[U.S. economists say high gasoline prices might lead motorists to drive more fuel-efficient vehicles, resulting in lower greenhouse-gas emissions.University of California-Davis economist Chris Knittel says that fewer miles being driven might make an important dent in the U.S. contribution to global warming by reducing annual carbon dioxide emissions by tens of millions of tons per year.Knittel and colleagues told New Scientist magazine they found sales of the least fuel-efficient cars fell by 13 percent for every $1 per gallon increase in the price of gasoline. And for every $1 hike in gas prices there was a corresponding 17 percent sales boost for the most efficient vehicles.]]></description>

<title>U.S. water data to be standardized</title>
<link>http://it.moldova.org/stiri/eng/118577/</link>
<description><![CDATA[U.S. scientists say they've started an initiative to create the first comprehensive data management system for the nation's water supply.The Hydrologic Information System, or HIS, is designed to supply the hundreds of municipal, state and federal agencies that control the nation's water resources with a common set of procedures for data collection, analysis, and reporting.The project, led by Professor David Maidment of the University of Texas at Austin,  was awarded a five-year grant from the National Science Foundation. Maidment will work in collaboration with the Consortium of Universities for the Advancement of Hydrologic Science Inc., a joint effort among more than 100 universities.]]></description>

<title>NASA, JAXA to conduct sonic boom research</title>
<link>http://it.moldova.org/stiri/eng/118573/</link>
<description><![CDATA[The U.S. space agency said it plans to join the Japan Aerospace Exploration Agency in conducting research on sonic boom modeling. The National Aeronautics and Space Administration said sonic boom modeling is needed to enable next generation of supersonic aircraft to fly quietly enough over land so they don't significantly disturb the public.Such a vehicle, said NASA, could connect Los Angeles and Tokyo in about two hours, flying at twice the speed of sound -- about 1,540 miles an hour.The two space agencies said they will also explore the possibility of further collaboration in aeronautics research and development, including the field of supersonic transport technology and possibly including JAXA's Silent Supersonic Technology Demonstration Project.]]></description>

<title>Mystery of Jupiter ring protrusion solved</title>
<link>http://it.moldova.org/stiri/eng/118570/</link>
<description><![CDATA[German and U.S. scientists say they've determined why dust particles from one of Jupiter's faint rings sometimes travel beyond the rings' normal boundary.Jupiter has 63 known moons, and the planet's faint rings are produced when debris from space collides with the four moons closest to the planet, researchers said. Although the rings are normally within the orbits of those moons, protrusions of dust sometimes extend beyond the orbit of Thebe -- the most-distant of the four closest moons.The cause of the protrusions has been a long-standing mystery.Now, Professor Douglas Hamilton of the University of Maryland and Harald Kruger of the Max-Planck Institute for Solar System Research in Germany say they've solved the mystery.]]></description>
