Internet Use Takes a Toll on Television Viewing
Americans with Internet access are watching less television, according
to the UCLA Internet Report 2001. The survey of 2,000 households
also shows that, as users get more on-line experience, their television
viewing declines further. Funded by the National Science Foundation
(NSF), the UCLA Internet Project polls non-users and users alike.
The objective is to survey populations in the U.S. and abroad for
an entire generation, and to get a comprehensive picture of how
the Internet is affecting society.

Scientists Succeed at First-Ever Attempt to Sequence DNA at Sea
Scientists funded in part by the National Science Foundation (NSF)
and affiliated from the University of Delaware and Amersham Biosciences,
Inc., in Piscataway, New Jersey, have succeeded in conducting the
first-ever DNA sequencing experiments at sea. Using the research
vessel Atlantis and submersible Alvin, the team carried
out a pioneering environmental genomic study of the strange life
that inhabits super-hot hydrothermal vents almost two miles deep
in the Pacific Ocean.

Melting
Glaciers Diminished Gulf Stream, Cooled Western Europe, During Last
Ice Age
At the end of the last Ice Age --11.5 to 13 thousand years ago --
the north Atlantic deep water circulation system that drives the
Gulf Stream may have shut down because of melting glaciers that
added freshwater into the north Atlantic Ocean over several hundred
years, confirm researchers funded by the National Science Foundation
(NSF)'s paleoclimate program. "For the first time, we have
shown that realistic additions of glacial meltwater into the north
Atlantic would have shut down north Atlantic deep water production
over a period of a few hundred years, if the initial ocean circulation
was somewhat weaker than that of today," said David Rind, lead
author of the study and a senior climate researcher at the NASA
Goddard Institute for Space Studies. The study appears in the current
issue of Journal of Geophysical Research - Atmospheres.

NSF-Funded
Terascale Computing System Ranks as World's Second Fastest
According to a new ranking of the world's fastest computers, the
National Science Foundation's (NSF) Terascale Computing System (TCS)
is the second most powerful. No other system for university-based
research can match its peak of 6 trillion calculations per second,
known as "teraflops." The TCS reached more than four teraflops
when running Linpack, a standard software test for comparing supercomputers.

Earth's
Ecosystems Slowed Greenhouse Gas Buildup in 1990s; Climate Change
Could Speed It
Earth's terrestrial ecosystems absorbed all of the carbon released
by deforestation and some of the carbon emitted by fossil-fuel burning
during the 1990s. But those ecosystems cannot be relied upon to
nullify carbons influence on global climate change in the
future, according to researchers funded partly by the National Science
Foundation (NSF) and affiliated with the National Center for Atmospheric
Research (NCAR) in Boulder, Colorado.
