April Flowers for redOrbit.com - Your Universe Online In the next few centuries, Canada's Arctic Archipelago glaciers will melt faster than ever, according to a new study. Research has revealed that 20 percent of the Canadian Arctic glaciers may have disappeared by the end of our current century, leading to an additional sea level rise of 1.4 inches. The findings, funded in part by EU's ice2sea program, are available online and will be published in an upcoming issue of Geophysical...
Pensoft Publishers A revision of the genus Copa offers a peculiar insight into spider biogeography in the Afrotropical Region The species from the genus Copa are very common spiders found in the leaf litter of various habitats. Being predominantly ground-living, they occur widely in savanna woodlands but also occasionally in forests, where they are well camouflaged. They usually share the litter microhabitats with several other species of the family Corinnidae. The spiders from this...
University of Arizona Antarctica's topography began changing from flat to fjord-filled starting about 34 million years ago, according to a new report from a University of Arizona-led team of geoscientists. Knowing when Antarctica's topography started shifting from a flat landscape to one with glaciers, fjords and mountains is important for modeling how the Antarctic ice sheet affects global climate and sea-level rise. Although radar surveys have revealed a rugged alpine landscape...
Group home destroyed by 2011 Japan disaster reopens tomorrow STAMFORD, Conn., March 6, 2013 /PRNewswire-USNewswire/ -- Japan tsunami survivors separated since the 2011 disaster will be reunited tomorrow with the opening of a new group home built by AmeriCares. The opening ceremony for the Momiji group home in Ofunato City comes just days before the second anniversary of the disaster. Two years after the tragic earthquake and tsunami, an estimated 300,000 survivors are still living...
Alan McStravick for redOrbit.com - Your Universe Online The quest to set foot on the North Pole began in the early 1800s but the realization of that quest had to wait nearly 100 years to occur. The US Navy engineer, Robert Peary, claimed (and not without more than a little controversy) to have reached the Pole on April 6, 1909. One of the most daunting obstacles in reaching the hometown of Mr. and Mrs. Claus is the ocean it is located in. Unlike the South Pole, the North Pole rests upon...
April Flowers for redOrbit.com - Your Universe Online The Isthmus of Panama uplifted 2.6 million years ago to form a land bridge connecting North and South America. This bridge has long been thought to be the crucial step in the interchange of animals between the Americas. Armadillos and giant sloths moved up into North America and ancient relatives of modern horses, rabbits, foxes, pigs, cats, dogs and elephants moved down into South America. A new study from the University of Florida...
National Science Foundation A century after Western explorers first crossed the dangerous landscapes of the Arctic and Antarctic, researchers funded by the National Science Foundation (NSF) have successfully deployed a self-guided robot that uses ground-penetrating radar to map deadly crevasses hidden in ice-covered terrains. Deployment of the robot--dubbed Yeti--could make Arctic and Antarctic explorations safer by revealing unseen fissures buried beneath ice and snow that could...
Lee Rannals for redOrbit.com – Your Universe Online NASA is best known for its explorations away from this planet, but the US space agency has a whole other program aimed at investigating the depths of this planet. One NASA researcher from the Jet Propulsion Laboratory in Pasadena, California joined up with an international Antarctic expedition last month to try and explore an unexplored aquatic environment on Earth. Alberto Behar used a small robotic sub about the size of a baseball...

Professor Jim Thomas leads international expedition in Papua New Guinea that finds new species of sea slugs, feather stars and amphipods, a shrimp-like animal When Jim Thomas and his global team of researchers returned to the Madang Lagoon in Papua New Guinea, they discovered a treasure trove of new species unknown to science. This is especially relevant as the research team consisted of scientists who had conducted a previous survey...

The dusky pademelon (Thylogale brunii), also known as the dusky wallaby, is a marsupial that can be found on the Kai and Aru islands, Papua New Guinea, and in the Trans Fly savanna and grasslands ecoregion in Papua Province in Indonesia. It prefers a habitat in both arid and tropical savannahs, forests, shrublands, lowlands, and grasslands. This species was named after its discoverer, Cornelis de Bruijn, and was once commonly known as philander, or “friend of man,” and the Aru Island...
Desert greening is made up of any number of methods used to revitalize deserts. So far, only arid and semi-arid desert are meant when using this expression. The icy deserts and other types are considered to be unsuitable. The different methods include landscaping methods to reduce evaporation, erosion, consolidation of topsoil, temperature, sandstorms and more, permaculture in general, planting trees, regeneration of salty, polluted, or degenerated soils, floodwater retention and...
Mammoth Cave National Park is located in the state of Kentucky in the United States. The park holds 52,830 acres of land that was once inhabited by Native Americans. Many mummies and artifacts have been found in Mammoth Cave and surrounding caves to support this. It is thought that first man of European descent to visit the area was John Houchin or Francis Houchin. The legend says that one of the brothers was hunting a wounded bear that entered the cave to hide. The first documented discovery...
Coral reefs are submerged structures consisting of calcium carbonate secreted by corals. Coral reefs are colonies of small animals found in marine waters that enclose few nutrients. The majority of coral reefs are constructed from stony corals, which then consist of polyps that come together in groups. The polyps are like small sea anemones, to which they are very closely related. Unlike the sea anemones, coral polyps secrete hard carbonate exoskeletons which provide support and protections...
Mudflats, or otherwise known as tidal flats, are coastal wetlands that form when mud is left behind by tides or rivers. They’re found in sheltered regions such as bayous, lagoons, estuaries, and bays. Mudflats might be seen geologically as exposed layers of bay mud, a result from the deposition of estuarine silts, marine animal detritus, and clays. The majority of the sediment in a mudflat is within the intertidal zone, therefore the flat is submerged and exposed about twice per day. In...
