Three
Nations Agree to Share Ice Core That May Yield Clues About Nature
of Lake Vostok
Scientists from the United States, France and Russia will equally
share samples of an 11.7-meter (38.5-foot) ice core taken from the
ice sheet above Lake Vostok, deep in the Antarctic interior, under
the terms of an agreement worked out among representatives of the
nations' Antarctic research programs. Glaciologists, geochemists
and biologists will use the lower portions of the Vostok ice core,
which was drilled in 1998, to learn more about the subglacial lake
known to exist under the ice at Russia's Vostok Station, high on
the polar plateau.

Ancient Flower Fossil Points
to Underwater Origins
The world's oldest known flower never bloomed, but it has opened
scientific questions into whether all of modern flowering plants
share underwater origins.The newly discovered remains of the oldest,
most complete flowering plant show it lived at least 125 million
years ago, most likely underwater, said University of Florida (UF)
paleobotanist David Dilcher. The discovery is reported in the Friday,
May 3, issue of the journal Science and was funded by the National
Science Foundation (NSF).

What Americans Know and Don't Know about Science -- Plus How R&D;
Affects the Economy, and More
Dramatic increases in research and development (R&D) investments
during the past decade, largely from industry, have contributed
to U.S. standing as a global economic powerhouse. However, developments
abroad could affect U.S. preeminence in science and technology in
the years to come, says Science and Engineering Indicators 2002,
a biennial report of the National Science Board to the President.

Science Leaders to Open Global Science & Technology Week with
Webcast
The White House Office of Science and Technology Policy (OSTP),
the National Science Foundation (NSF) and other agencies will celebrate
Global Science & Technology Week (GSTW) April 28-May 4. The
theme is "Science and Technology: Serving Our Global Community."
NSF has organized a two-hour Webcast, "Meet a Scientist or
Engineer," April 29. It will feature the nation's top scientists
at several sites taking questions from middle school students. David
Heil, formerly the host of Newton's Apple, will moderate. OSTP Director
John Marburger and NSF Director Rita Colwell will co-host.

Crossing
Alaska By Snowmobile in Search of Climate-Change Clues
A group of scientists left Nome, Alaska in late March on a 35-day
snowmobile traverse to scour the Alaskan tundra for clues to the
role snow cover plays in climate change. The team also will analyze
the chemistry and composition of snow along the route to determine
the source of the snow, and how much it has been affected by arctic
haze. Supported by the National Science Foundation (NSF), the six-
member Snow Science Traverse - Alaska Region (SnowSTAR 2002) expedition
plans to cover 1,100 kilometers (700 miles) -- from Nome, northeast
through the Brooks mountain range to Barrow.

Researchers Attempt
to Identify When, Where Volcanoes will Erupt
Researchers funded by the National Science Foundation (NSF) and
affiliated with the State University of New York (SUNY) at Buffalo
are developing technology that may identify not only where and when
a volcano will come to life, but the path its destructive lava flows
will follow. Combining mathematical modeling, geologic simulations,
geographic information science, scientific computing and virtual
reality, the researchers will provide accurate information on geologic
dangers to scientists, civil-defense authorities, and citizens who
live in the shadow of a volcano.

Researchers Capture
Image of Unusual Blue Jet Lightning
Deep in the tropical jungle of Puerto Rico lies the NSF's Arecibo
Observatory, where for the first time a team of researchers has
captured video evidence from the ground of a lightning phenomenon
known as a blue jet. The discovery is the first ground-based evidence
linking the ionosphere with cloud tops in blue jet events. According
to Victor Pasko of Penn State, an electrical engineer working at
Arecibo, "Pilots and others reported observations of red sprites
and blue jets long before the first one was captured on video, and
numerous undocumented reports of similar phenomena have appeared
in scientific literature for over a century."
