Researchers find 24 species believed new to science in Suriname rainforest

...of Paramaribo, the capital. They found a virtually unexplored region of mountain savannah forest, high dryland rainforest and palm swamp with freshwater sources clean enough to support abundant fish and amphibian life. Among the 24 species believed new to science are an Atelopus frog with brilliant purple ma...

New bird discovered on unexplored Columbian mountain

... new bird to science was recently discovered on an unexplored mountain range in northern Colombia by a team supported by the BP Conservation Programme. It was named "Yariguies Brush-Finch," with the scientific name Atlapetes latinuchus yariguierum. The new brush-finch was described by an Anglo-Colombian team ...

Bacteria that use radiated water as food

...f the ocean. The rocky crust on Earth is virtually unexplored at depths more than half a kilometer below the surface.

Deep-water discovery

...st majority of the ocean remains poorly mapped and unexplored ?even off Miami ?these potentially important areas remained unseen. In December 2005, as part of the NOAA Ocean Exploration program, Rosenstiel School researchers, led by Professors Grasmueck and Gregor Eberli, began mapping deepwater habitats off M...

The survey of a previously unexplored region in March 2006 by scientists from Conservation International and its partners documented a much greater variety of life than expected, including one fish species believed new to science and 17 others noted for the first time in the waters off M...

Biologists develop genome-wide map of miRNA-mRNA interactions

The thousands of genome-wide miRNA target predictions for nematodes, or roundworms, humans, and flies are available from the PicTar website (pictar.bio.nyu.edu) and are linked to a new graphical network-browsing tool d...

The Antarctic Ocean floor

.... The reason why these waters have remained almost unexplored is due to its adverse climate which, in turn, has assured that human presence has been scarce. On this present campaign the scientists will trawl the ocean floor at up to 2000 metres depth, using both Agassiz-trawl fitted with a closed net as well a...
