ANCIENT LAKE MAY HAVE DISRUPTED CLIMATE
from Associated Press via Sigma Xi Science in the News
WASHINGTON -- A massive freshwater lake that covered much of
southern Canada 8,200 years ago burst through its ice dam and flooded
into the Atlantic, disrupting ocean currents and causing a climate
change that chilled the Northern Hemisphere for 200 years, a study
suggests.
The ancient body of water, called Lake Agassiz, was formed by
ice dams that blocked drainage from the vast central plains of Canada
during the fading centuries of the last ice age. The lake once was
more than twice the size of the current Great Lakes and contained
more than 39,000 cubic miles of water.
At its most expanded, Lake Agassiz stretched from western
Manitoba, east to Quebec and south to North Dakota and Minnesota,
some 135,000 square miles.

MICROBE CAN SURVIVE AT 226 DEGREES
from Associated Press via Sigma Xi Science in the News
WASHINGTON -- Some may like it hot, but nothing likes it hotter
than a weird microbe known as Strain 121. The one-celled organism,
captured from a magma vent at the bottom of the Pacific Ocean, can
survive 266 degrees, a temperature no other known life form can
tolerate.
The as-yet-unnamed microbe was able to reproduce and grow
vigorously at about 250 degrees, the typical temperature used in
autoclaves to sterilize
medical instruments, said Derek R. Lovley, a University of Massachusetts
microbiologist who was the senior author of a study appearing Friday in the
journal Science.
"It has been the dogma in microbiology for 120 years that that temperature
would kill any living organism," Lovley said.
But not Strain 121.
