Biotechnology
seems to be leading a sudden new biological revolution. It has
brought us to the brink of a world of "engineered" products that are
based in the natural world rather than on chemical and industrial
processes.
Biotechnology has been described as "Janus-faced." This implies that
there are two sides. On one, techniques allow DNA to be manipulated to
move genes from one organism to another. On the other, it involves
relatively new technologies whose consequences are untested and should
be met with caution
The ocean dumps literally tons of plastic trash on Hawaii’s Kamilo Beach each year.
Kamilo, on the Big Island of Hawaii, is no ordinary beach. While it
has sand, most of the island is made up of cooled chunks of lava rock
that formed when Mauna Loa, one of the island’s volcanoes, erupted in
1868.
There are no roads that lead to Kamilo (pronounced: ka-MEE-low).
What
a difference! These two images of the sun’s outer atmosphere, or
corona, were taken about 20 months apart. The sun is quiet in the
picture at left, taken in January 1997. In the picture at right, taken
in November 1998, the sun is more active.
Plastic
contains polymers, molecules that are linked into long chains. Under a
microscope, polymers resemble a bowl of tangled spaghetti.
If you looked at the plastic in your sneakers under a high-powered
microscope, it would resemble cooked spaghetti, with each noodle tangled
in the others.
The
space shuttle Atlantis lifts off in May 2010, headed for the
International Space Station more than 200 miles above Earth.
At the Kennedy Space Center on Cape Canaveral, Fla., the space
shuttle Atlantis awaits its last liftoff. In June, it will be rolled to
the launchpad, within sight of the white sands of the Atlantic coast. In
the past 30 years, 134 previous space shuttle missions have launched
from the same swath of land.
