Birds bizarre (Nature Science Updates 3/26)
"A report in the 19 March 1998 issue of Nature describes a creature that looks superficially like a dinosaur, but detailed examination of its skull shows it to have been more closely related to modern birds than is the famous 'first bird', Archaeopteryx. But his new creature, and its close relatives, did not have wings and could not fly."
Early Oceans Touch Civilization Today (Science Daily 3/25)
"It was a chilly Thursday morning in November 1980 when, just before dawn, the drill bit from the oil rig on Lake Peigneur on Jefferson Island, La., punctured the roof of the Diamond Crystal salt dome beneath the lake.

Research Shows Why Big Quake Accompanied By Many Smaller Ones (Science Daily 3/18)
"Two Columbia University scientists have devised a computer model that shows how during geologic deformation, earthquakes in a specific location and time period will occur in a pyramidal distribution, with one larger quake and a specific number of smaller ones in no particular order."
Crater Chain On Two Continents Points To Impact From Fragmented Comet (Science Daily 3/17)
"A team of scientists working on two continents has discovered that a series of five craters on Europe and North America form a chain, indicating the breakup and subsequent impact of a comet or asteroid that collided with Earth approximately 214 million years ago."
Researchers Invent New Way To See Underground (Science Daily 3/17)
"A new method for making images of the subsurface has been devised by Ki Ha Lee of the Department of Energy's Lawrence Berkeley National Laboratory. Lee and his colleagues in the Earth Sciences Division use data generated with electromagnetic energy (EM) in a novel way that can visualize the subsurface at depths ranging from gas and oil reservoirs thousands of meters deep to plumes of pollutants in shallow soil."
NASA: Asteroid to miss Earth by a wide margin (CNN 3/12)
"NASA scientists said Thursday there is no chance -- 'zero' in the words of one astronomer -- that the asteroid known as 1997 XF11 will come any closer than 600,000 miles from Earth."
Mile-wide asteroid on course for near-miss with Earth (CNN 3/11)
"Astronomers say a mile-wide asteroid described as "the most dangerous one we've found so far" may be on course for a near-miss -- or even a collision -- with Earth in the year 2028. The Central Bureau for Astronomical Telegrams -- which tracks asteroids -- conducted further observations that determined 1997 XF11 should pass just under 30,000 miles from Earth on October 26, 2028."
Antarctic Rocks Yield Clues About Global Change (Science Daily 3/12)
"In the Journal of Geology, (1997, vol. 105, p. 285-294), a UMaine team has published new evidence consistent with the view that the East Antarctic ice sheet remained stable during that period [the last 3-4 million years] and did not melt as other researchers have suggested."
Bolivia climate change project finalized (CNN/ENN 3/11)
"The Bolivian government Monday signed an agreement with The Nature Conservancy, three major U.S. corporations and a Bolivian conservation organization to begin a forest conservation project designed to help reduce global greenhouse gas emissions."
Requiem for a spacecraft: Pathfinder is dead (CNN 3/10)
"Scientists failed in a final effort to contact the Pathfinder on Tuesday, and declared the craft officially "dead" four months after the end of a mission that produced the closest-ever look at the red planet's surface."
Recent El Ninos 'Unlikely To Be Caused By Past Warming Trend' (Science Daily 3/10)

New Dating Technique May Revise Geologic Time Scale (Science Daily 3/6)
"A team of researchers at the University of Toronto and the Université P. et M. Curie in Paris has developed a method to directly date individual grains of a group of clay minerals, called glaucony, that commonly form within sediments while they are being deposited in water."
Tsunami Hunters Probe Lake Bottoms For Clues (Science Daily 3/6)
" Exactly how big the tsunamis will be and how far inland they will reach depends on the intensity of the earthquake. Still, the best way to predict what might happen is to look back and see what's already happened. That's why a group of scientists, including SFU geographer Ian Hutchinson and plant paleontologist Rolf Mathewes, have spent the last three years probing the gooey depths of several tiny lakes on the west coast of Vancouver Island. Preliminary results of their study suggest that tsunamis on Canada's exposed west coast may be smaller than previously thought."

SFU Geologist Finds Evidence Of Australia/North America Link (Science Daily 3/5)
"hinking of going to Australia but dreading the long flight over the Pacific Ocean? Ponder this: if you'd been around 1.6 billion years ago, you could have walked from British Columbia. That's because mounting evidence suggests that the land mass we know as Australia may once have been joined to North America at the Yukon before drifting apart about one billion years ago."
Walk this way (Nature Science Updates 3/5)
"Pterosaurs ability to fly is not in doubt – flying pterosaurs are known that range in size from sparrows to small aircraft – but how did they move when they were on the ground? Were they fleet-footed runners, sprinting along on their toes? Or were they waddling, four-footed sprawlers, like bats? "
Deal to prevent Yellowstone mine close to being sealed (CNN/Environmental News Network 3/4)
