The chance discovery of a vast ecosystem beneath the collapsed Larsen Ice Shelf will allow scientists to explore the uncharted life below Antarcticas floating ice shelves and further probe the origins of life in extreme environments. Researchers discovered the sunless habitat after a recent underwater video study examining a deep glacial trough in the northwestern Weddell Sea following the sudden Larsen B shelf collapse in 2002.
“This is definitely the biggest thing I
Scientists face difficult challenges in predicting and understanding how much our climate is changing. When it comes to gases that trap heat in our atmosphere, called greenhouse gases (GHGs), scientists typically look at how much of the gases exist in the atmosphere.
However, Drew Shindell, a climatologist at NASA’s Goddard Institute for Space Studies, New York, NY, believes we need to look at the GHGs when they are emitted at Earth’s surface, instead of looking at the GHGs themse
Mercury and DDT are 60X higher as a result of bird droppings, say researchers
Seabirds are the surprising culprits in delivering pollutants – through their guano – to seemingly pristine northern ecosystems, a new Canadian study shows.
The most common form of wildlife in the Arctic, seabirds are responsible for transporting most of the human-made contaminants to some coastal ecosystems, the researchers found. “The effect is to elevate concentrations of pollutants such a
Thanks to extensive GPS measurements and analyses by TU Delft and its scientific partners, unique images showing the development of the earthquake on 26 December 2004 in South East Asia have been created. This is the first time that a quake of such magnitude has been recorded and made visible using GPS. Today, Thursday 14 July 2005, an article on this subject will be published in the scientific journal Nature.

Microtubules need a helping hand to find chromosomes in dividing egg cells, scientists have discovered. Although it was generally accepted that microtubules act alone as the cellular ropes to pull chromosomes into place, a new study by researchers at the European Molecular Biology Laboratory (EMBL) shows that this is not the case. They found that in large cells such as animal eggs, something else is needed to move the chromosomes into the correct location – fibres of the cytoskeletal molecule actin
Unusually preserved fossils shed new light on how macroscopic, complex life evolved and lived 550 million years ago
Scientists interested in ancient life have a wealth of fossils and impressions frozen in rocks that they can study from as far back as 540 million years ago – when animals with shells and bones began to become plentiful. But evidence of complex life older than 540 million years is scant and difficult to study.
Now, a research team from Virginia Tech in
