Census of Marine Life explorers surprised by diversity, density of Arctic creatures
... the Larsen B ice shelf on the Antarctic Peninsula collapsed
in early 2002. Roughly 500 billion tonnes of ice sheet (3,250 square kilometers, about the size of Rhode Island) disintegrated in less than a month, what scientists have called "staggering" speed. The work builds on that of marine scientists who hav...
Discovering an ecosystem beneath a collapsed Antarctic ice shelf
...e chance discovery of a vast ecosystem beneath the collapsed
Larsen Ice Shelf will allow scientists to explore the uncharted life below Antarctica's floating ice shelves and further probe the origins of life in extreme environments. Researchers discovered the sunless habitat after a recent underwater video stu...
Global warming may have damaged coral reefs forever
...largely unable to reseed and recover. Many simply collapsed
into rubble which became covered by unsightly algae. The collapse of the reefs removed food and shelter from predators for a large and diverse amount of marine life - in 2005 average coral cover in the area surveyed was just 7.5 per cent. The sur...
By 2048 all current fish, seafood species projected to collapse
...said, "29 percent of fish and seafood species have collapsed
-- that is their catch has declined by 90 percent. It is a very clear trend, and it is accelerating. We don't have to use models to understand this trend; it is based on all the available data." Researchers also determined that the problem is much ...
Scripps research study reveals structural dynamics of single prion molecules
...5 lacks a specific, static structure in its native collapsed
state. Instead, the compact protein fluctuates among several different structures before forming intermediate shapes during the amyloid assembly process. The intermediate stages of the process are critically important, Deniz noted: "No single nat...
'Virtual autopsy' helps identify drowning as cause of death
... fluid. All members of the control group exhibited collapsed
stomachs. Autopsy results in these categories were similar to MDCT results for both study groups. "Airway froth and sediment can be demonstrated on MDCT and were specific to drowning, thereby replicating the findings seen at autopsy," said Dr. ...
