Peat deposit at reservoir site may fill gaps in Southern California's paleontological record (Reuters Business Wire 6/13/97)
Ice Age bison fossils may date reservoir site 30,000 years (Reuters Business Wire 6/13/97)
"When construction crews at the Metropolitan Water District's Eastside Reservoir Project near Hemet unearthed a channel of peat, scientists knew they had struck paleontologic gold. The discovery of the extensive peat deposit, they say, will allow them to determine the age of mammal fossils uncovered at the site. It also means they can document the types of ecosystems that thrived in Southern California's inland valleys up to 30,000 years ago."
New Zealand hit by meteor or space debris (Nando Times/AP 6/13/97)
"A brightly burning object crashed into New Zealand's North Island Friday in what police and scientists believe was a shower of meteors or space debris."
Distant encounters of the third kind (Nature Science Updates 6/12/97)
"The discovery of a large and icy asteroid in the dark and distant reaches of the outer Solar System shows that the remoter parts of our own planetary system are not quite as desolate and unpopulated as had been thought. The most interesting feature about this freezing, icy worldlet is its somewhat comet-like orbit."
Earth's Pet Rock (Science Now 6/11/97)
Earth, Asteroid Move in Tandem (Washington Post/AP 6/11/97)
"At first sight, it looked like an ordinary asteroid. It is anything but. In tomorrow's issue of Nature, three astronomers report that a 5-kilometer-wide rock follows Earth around the sun in a complicated, horseshoe-shaped orbit, making it Earth's only companion object besides the moon."
Star birth explains Earth's odd composition (Reuters 6/11/97)
"A group of astronomers says their theory that depicts the young sun as a hot, spewing blob at the center of a spiralling disk of gas and dust also solves a long-standing puzzle about Earth's composition. Team leader Frank Shu says winds from the star-forming process that seeded the dusty accumulation that eventually became Earth carried away both the planet's easily vaporized components and _ oddly _ its hardest- to-melt ones as well."
New light in heavens in 2005 (MSNBC/AP 6/11/97)

A Bloodstained T. rex? (Science Now 6/9/97)
"Scientists say they have turned the tables by extracting blood--or at least one of its key components, hemoglobin--from a T. rex bone. If the finding holds up, it would give scientists an extremely powerful way to trace the evolution of the giant theropods."
Rocky Mountain Why (Earth Magazine June 97)
"Continental fender bender or big scoop taken from America's middle? Nobody really knows what raised the Rockies."
Radar challenges notion of ice on moon (Nando Times/AP 6/7/97)
"Detailed radar images offer no evidence of ice on the moon, data that appears to contradict scientists' earlier conclusions, say astronomers at Cornell University's Arecibo Observatory. The scientists say in an article in this week's Science that the unmanned Clementine spacecraft probably saw 'very rough surfaces associated with the steep slopes of impact craters.'"
Fossil Hatchling Heats Up Bird-Dinosaur Debate (InScight 6/5/97)

Climate: Farmers reap benefits from global warming (Nature Science Updates 6/4/97)
"Global warming could be a source of temporary good news for farmers. New research suggests that the rise in average annual temperatures has led to increases in wheat yields in Australia. The benefits of course may be short lived. If, as predicted, sea levels continue to rise from man-made climate change, there may be no land left on which to farm."
Galileo Finds Wet Spots, Dry Spots and New View of Jupiter's Light Show (NASA News Release 6/5/97)
Jupiter has wet, dry areas mirroring Earth's (CNN 6/5/97)
Galileo: Jupiter Has Wet and Dry Areas (Washington Post/AP 6/5/97)
"Jupiter has both wet and dry regions, just as Earth has tropics and deserts, according to new images and data from the Galileo spacecraft released today. The data may explain why Galileo's atmospheric probe found much less water than scientists had anticipated when it dropped into the Jovian atmosphere in December 1995." (CNN Quicktime Movie)
Our Solar System Is Getting Crowded (Science Now 6/4/97)
Icy miniplanet found in solar system (CNN/AP 6/4/97)
Icy miniplanet found beyond Pluto (MSNBC 6/4/97)
"Astronomers have discovered a new class of the icy bodies left over from the formation of the solar system, inhabiting a region of space once thought to be barren. A paper in this week's issue of Nature describes the first such object, and a computer model appearing in next week's Science explains how they came to populate the space far beyond Neptune."
Smithsonian Show Features Amber (Washington Post/AP 6/4/97)
"The ultimate marriage of science and art, from the dinosaurs of Jurassic Park to the Baroque splendor of Russia's amber room, goes on display Friday at the Smithsonian Institution. 'Amber: Window to the Past' looks at millions of years of preserved plants and animals and thousands of years of craftsmanship in turning ancient plant sap into objects of art."
Panoramas of the Seafloor (Scientific American 6/97)
"Seven tenths of the earth's surface is covered with water--what's down there? A new breed of computer-equipped cartographers is finding out. With measurements from the newest generation of sonar-equipped ships outfitted with multibeam sonar, scientists are mapping the depths of the U.S. continental margins in exquisite detail."
Bigger hurricanes and more of them expected, forecasters say (Nando Times/New York Times 6/3/97)
"The East and Gulf Coasts of the United States may be entering a long-anticipated, prolonged siege of more frequent and more destructive hurricanes, forecasters say. They predict that this summer, more hurricanes than normal will develop in the tropical North Atlantic for the third straight year. This would make 1995-97 the most active three-year period on record for the pinwheeling oceanic cyclones, and the experts say that could be only the beginning."
