NSB Task Force on Environment
to Hold Portland, OR Hearing Jan. 14
The National Science Board (NSB) Task Force on
the Environment was established to assist NSF in defining
the scope of its role with respect to environmental
research, education, and assessment, and in determining
the best means of implementing activities related
to this area. The Task Force will be holding an open
Hearing on Environmental Research, Education and Assessment
on January 14, 1999 at the Hilton Hotel, Portland,
OR. For more information on the hearing and future
activities of the Task Force, and to provide comments
on issues under consideration, visit the NSB Task
Force Web site (http://www.nsf.gov/nsb/tfe/start.htm).

Today / Gallup Poll: Americans and the Y2K Millennium
Computer Bug
While a majority of Americans think computer
mistakes due to the Year-2000 issue will cause only
minor problems, nearly half surveyed said they would
avoid travelling on airplanes on or around January
1, 2000, and nearly two-thirds said they would seek
extra confirmation of bank account, retirement fund
or other financial records, according to a recent
Gallup poll. The nationwide telephone poll, released
by the National Science Foundation (NSF) and USA Today,
surveyed 1,032 adults between December 9 and 13. "This
poll shows much of the American public is aware of
possible Year 2000 computer mistakes," said George
Strawn, NSF's Computer Networking Division Director.
"This underscores how truly integrated computers already
are in our everyday lives, and how much we depend
on them." More...

National
Science Medalists Named
President Clinton on December 8th named nine
of the nation's most renowned scientific researchers
to receive the National Medal of Science, citing them
for "their creativity, resolve, and a restless spirit
of innovation to ensure continued U.S. leadership
across the frontiers of scientific knowledge." The
individuals awarded the nation's highest scientific
honor have had wide-ranging impact on social policy,
cancer research, materials science, and greatly extended
knowledge of our Earth and the solar systems. "These
are superstars in their respective fields," Rita Colwell,
director of the National Science Foundation (NSF),
said.

High School
Students Discover Distant Asteroid Using NSF Telescope
and Education Program
High school students have discovered a previously
unidentified celestial object in the Kuiper Belt using
images from the National Science Foundation's (NSF)
4-meter Blanco Telescope in Chile. Heather McCurdy,
Miriam Gustafson and George Peterson of Northfield
Mount Hermon School in Northfield, Massachusetts,
one of six Asteroid Search Teams at the school participating
in NSF's innovative Hands-On Universe Program, found
and verified the distant object. "Only about 72 such
objects had been identified in the Kuiper Belt," says
astronomy teacher Hughes Pack. Kuiper Belt Objects,
found beyond Neptune, are generally believed to be
remnants dating to the formation of our solar system.

Scientist
Finds Asteroid Fossil that May Have Caused Global
Dinosaur Extinction
The fossilized
remnants of an asteroid that may have caused the global
extinction of dinosaurs and other species more than
65 million years ago has been found by a National
Science Foundation (NSF) funded researcher. Frank
Kyte, a geochemist from University of California at
Los Angeles (UCLA), presents his analysis of the fossil
meteorite in the November 19 issue of the journal
Nature. Some scientists believe that
this particular worldwide extinction, which ended
the Cretaceous period 65 million years ago, was caused
by the destructive impact of a comet or asteroid.
Kyte found the fossil meteorite while studying the
sediment boundary layer between the Cretaceous and
Tertiary eras.

Drying
Rock Can Cause Repeated Earthquakes
Physical changes
within rocks below fault zones may lead to repeated
earthquakes, according to NSF-funded geologists. Researchers
Jay Ague, Jeffrey Park and Danny Rye of Yale University
in New Haven, Connecticut, analyzed chemical reactions
within Earth's middle crust, about 10-20 kilometers
(6-12 miles) beneath the surface. Their study shows
that rocks subjected to increases in pressure and
temperature, such as those found in faults along boundaries
where tectonic plates slide past each other, may release
water over time. Loss of water and resulting increases
in internal fluid pressures can cause these rocks
to break, and possibly cause an earthquake -- if that
break happens near an active fault line, like the
San Andreas Fault.
