Turkish Earthquake Report Reminds U.S. Of Need To repare(Science Daily 4/28)
The release of new probability figures for the occurrence of large earthquakes on the North Anatolian fault in Turkey serves as a reminder that citizens, private industry and government agencies in the United States need to take steps to lessen damage, injuries and loss of life from earthquakes of the same magnitude that could occur in the U.S.
Cosm ologists Reveal First Detailed Images Of Early Universe (Science Daily 4/27)
An international team of cosmologists has released the first detailed images of the universe in its infancy. The images reveal the structure that existed in the universe when it was a tiny fraction of its current age and 1,000 times smaller and hotter than it is today. Detailed analysis of the images is already shedding light on some of cosmology's outstanding mysteries -- the nature of the matter and energy that dominate intergalactic space and whether space is "curved" or "flat."
Wash ington State University Professor Studies Reemergence Of Life On Mount St. Helens 20 Years After Disastrous Eruption (Science Daily 4/27)
Thursday, May 18 is the 20th anniversary of Mount St. Helen's eruption in 1980. How is the mountain recovering? What types of vegetation have grown in areas wiped out by lava and ash? What are expectations for future growth?
NASA Scientist: Lightning Studies May Provide Earlier Tornado Alerts (Science Daily 4/26)
On May 3, 1999, more than 50 tornadoes cut a killer swath across the Great Plains, taking more than 40 lives. One year later, NASA researcher Steve Goodman demonstrates how another foul-weather hazard -- lightning -- could be the key to predicting such devastating storms.
Gali leo Takes Risky Trip To Dribble Back Data Revealing Best Images Yet Of Jupiter's Cratered Inner Moons (Science Daily 4/25)
The Galileo spacecraft has taken a risky spin through Jupiter's lethal radiation belts to capture the highest-resolution images yet of three of the planet's four innermost moons, Thebe, Amalthea and Metis. In particular, two views of Jupiter's 250-kilometer-long (155 miles), irregularly shaped moon Amalthea, obtained by Galileo's Solid State Imaging camera (SSI) last August and November, show for the first time that a bright surface feature named Ida is a streak of bright material, about 50 kilometers (31 miles) in length.
New 3-D Flyover Of Los Angeles-Area Quake Faults (Science Daily 4/24)
NASA Television is airing a new computer-animated 3-D flyover of the Los Angeles area, created with detailed mapping data from NASA's recent Shuttle Radar Topography Mission. The video takes viewers zooming along a 90-mile stretch of the San Andreas fault to the intersection of the Mojave Desert's Garlock fault -- one of the region's greatest quake hazards.
Scie ntists Discover 66-Million-Year-Old Dinosaur With A Heart (Science Daily 4/21)
Scientists at North Carolina State University and the North Carolina Museum of Natural Sciences have discovered the world's first dinosaur specimen with a fossilized heart. They report the historic finding in the April 21 issue of the journal Science.
Unit ed States Experienced Warmest First Three Months Of The Year On Record (Science Daily 4/19)
The United States has just experienced the warmest January - March period ever, according to 106 years of record-keeping compiled by NOAA. The latest data also show that June 1999 - March 2000 was the warmest June - March on record
Watc hing The Snow Melt Predicts Flooding And Drought (Science Daily 4/18)
Hydrometeorologists with the National Oceanographic and Atmospheric Administration (NOAA) are using two planes to monitor how much water is in the snowpack over 25 states and 7 Canadian Provinces. This provides important information about whether we will face flooding or drought in coming months.
Loui siana Professor Taking The Guesswork Out Of Hurricane-Surge Predictions (Science Daily 4/17)
When Hurricane Georges was barreling toward Louisiana's coastline in 1998, no one knew how accurate the storm surges predicted by meteorologists would be, LSU professor Gregory Stone said. But Stone is trying to change all that, hoping to significantly improve the predictive power of computer models through measurement of storm surge and other oceanographic phenomena in the Gulf of Mexico.
Eart h Could Lose Thousands Of At-Risk Species: Studies Indicate Extinctions Are Not Random Events (Science Daily 4/14)
Thousands of at-risk bird and mammal species worldwide could eventually become extinct due to the non-random nature of extinction events.
