redOrbit Staff & Wire Reports - Your Universe Online The fossils of microscopic aquatic creatures, whose shells resemble grains of sand to the naked eye, could help shed new light on the process of evolution, according to new research published Friday in the journal Methods in Ecology & Evolution. As part of their research, University of Southampton evolutionary ecologist Dr. Thomas Ezard and his colleagues are analyzing the remains of the one-millimeter large planktonic...

By Robert Sanders, University of California, Berkeley Millimeter-size marine organisms called foraminifera have been used to monitor pollutants in marshes and oceans, and could help to assess recovery in the Gulf of Mexico following the three-month long Deepwater Horizon oil spill. That was the message from a French/American team of researchers who recently reported on the health of French marshes and mudflats 32 years after the Amoco Cadiz spilled 220,000 tons of oil along the Brittany coast...

Evidence from the Challenger Deep "“ the deepest surveyed point in the world's oceans "“ suggests that tiny single-celled creatures called foraminifera living at extreme depths of more than ten kilometers build their homes using material that sinks down from near the ocean surface. The Challenger Deep is located in the Mariana Trench in the western Pacific Ocean. It lies in the hadal zone beyond the abyssal zone, and plunges down to a water depth of around 11 kilometers. "The...

Drifting across the world's oceans are a group of unicellular marine microorganisms that are not only a crucial source of food for other marine life "” but their fossils, which are found in abundance, provide scientists with an extraordinary record of climatic change and other major events in the history of the earth. Now, planktonic foraminifera "” single-celled shell building members of the marine microplankton community "” have given up a secret of their very own.A team...

In 2004 and now in 2005, the hurricane seasons have been horrifyingly intense "“ so how bad is the long-range forecast? Based on a century of data, meteorologists currently believe that a 30-year lull in hurricane activity is over and we are at the beginning of a new multi-decade period of larger and more frequent storms. However, there is other data that suggests we may also be coming to the end of a thousand year period of greatly diminished hurricane activity, making the outlook even...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
