Sunlight, not bacteria, key to CO2 in Arctic

Washington, Aug 22 (IANS) Sunlight and not bacteria is the key to triggering the production of carbon dioxide (CO2) from material released by Arctic soils, says a significant study. The vast reservoir of carbon stored in Arctic permafrost (permanently frozen soil) is gradually being converted to carbon dioxide (CO2) after entering the freshwater system in a process which has so far been ...

Human skin fungus tracked to deep sea animals

New York, Aug 22 (IANS) A ubiquitous skin fungus linked to dandruff, eczema and other itchy, flaky maladies in humans has now been tracked to Hawaiian coral reefs and the extreme environments of arctic soils and deep sea vents. We have found multiple new examples of fungi of the genus Malassezia on corals, sponges and algae and in water samples, deep sea thermal vents and sediments from ...

Life brimming with active ecosystem beneath Antarctic ice

Washington, Aug 21 (IANS) A lake that has not seen sunlight or felt a breath of wind for millions of years beneath the Antarctic ice is brimming with life and active ecosystem, reveal findings of a massive US expedition. The life is in the form of microorganisms that live one-and-a-half mile below the surface of the West Antarctic Ice Sheet and convert ammonium and methane into the energ...

Tibet plateau getting hotter, polluted: Report

Beijing, Aug 20 (IANS) A fresh environmental assessment of the Tibetan Plateau has found that the region is getting hotter, wetter and more polluted, threatening its fragile eco-systems and those who rely on them. The report, released in Lhasa by the Chinese Academy of Sciences (CAS) and the government of Tibet, finds that precipitation has risen by 12 percent since 1960 and temperatures...

Exceptional iceberg to blame for Titanic disaster?

London, Aug 19 (IANS) While the sinking of the Titanic in 1912 is typically blamed on human, design and construction errors, a study points to two other unfavourable factors outside human control. There were a greater number of icebergs than normal that year, and weather conditions had driven them further south and earlier in the year than usual, the researchers said. The RMS Tit...

Snow cover on Arctic sea ice has thinned significantly: NASA

Washington, Aug 18 (IANS) In an alarming revelation, NASA has confirmed that the snow on sea ice in the Arctic has thinned significantly in the last 50 years - by about a third in the western hemisphere and by half near Alaska. The research by NASA and University of Washington, Seattle recorded changes in snow depth over decades by combining data from various sources. In the stud...

Antarctic ice melt may accelerate sea level rise

London, Aug 14 (IANS) The ice discharge from Antarctica could become the largest contributor to sea level rise much sooner than previously thought, says a study. If greenhouse gases continue to rise, ice discharge from Antarctica could raise the global ocean by an additional 1-37 centimetres in this century already, said lead author Anders Levermann, a climatologist and professor at the ...

Antarctic researchers lose heating at -55 degrees

London, Aug 8 (IANS) A group of British researchers faced a 19-hour power outage in Antarctic's freezing temperatures after a serious operational incident at their research facility in the world's southernmost continent, a media report said Friday. The 13-member British Antarctic Survey (BAS) team has since last month been dealing with a yet unidentified technical snag at the Halley Rese...

Methane created mysterious Siberian crater: Study

London, Aug 1 (IANS) The mysterious crater spotted in the frozen Yamal peninsula in Siberia earlier this month was probably caused by methane released as permafrost thawed, Russian researchers say. Air near the bottom of the crater contained unusually high concentrations of methane - up to 9.6 percent - in tests conducted at the site, said Andrei Plekhanov, an archaeologist at the Scient...

Decreased carbon dioxide formed Antarctic ice sheet?

New York, July 31 (IANS) Turning a long-held climate shift theory on its head, researchers have found that decreased carbon dioxide (CO2) levels during a major climate shift 34 million years ago led to initiation of Antarctic glaciation. The finding counters a 40-year-old theory suggesting massive rearrangements of the Earth's continents caused global cooling and the abrupt formation of ...

Arctic new training ground for Mars exploration

Washington, July 30 (IANS) A team of NASA scientists is testing new equipment in Nunavut, the northernmost territory in Canada, to better equip themselves for exploring Mars. Describing the island as a living laboratory, scientists say that like Mars, the high Arctic is perpetually cold and exposed to the elements. The uninhabited island is a rocky polar desert marked by an ancie...

New mayfly species discovered in India

New York, July 28 (IANS) Scientists have found a new species of mayfly in the southern Western Ghats, a mountain range along India's west coast. This is the first time that any mayfly belonging to the genus Labiobaetis has been found in peninsular India. The new species, called Labiobaetis soldani, is named in honour of T. Soldan for his substantial contribution in the understand...

Wherever I may roam: Travelling in the subcontinent

What drives people to leave the comforts of their home and familiar surroundings to explore other lands near and far? Can we ascribe it to the human fascination to visit new places, see how other people live, or obtain fresh experiences? Or are they simply echoing life, which itself is a journey in time and space? Travel also always had a close relation with literature. One of the most e...

Antarctic fish might survive ocean warming: Study

Wellington, July 24 (IANS) A species of Antarctic fish might be able to survive the predicted warming of its native waters over the next century if the warming is gradual enough, according to a New Zealand scientist. University of Canterbury researcher Charlotte Austin tested how the emerald rock cod adapted to warmer waters after being removed from its minus 1.9-degree centigrade habita...

Research questions satellite data over Antarctic sea expansion

Washington, July 23 (IANS) The Antarctic sea ice may not be expanding as fast as previously thought, a new research suggests, adding that there may be a processing error in the satellite data. Arctic sea ice is retreating at a dramatic rate. In contrast, satellite observations suggest that sea ice cover in the Antarctic is expanding and that sea ice extent has reached record highs in rec...

Life in Mars? Ancient Earth-like soils provides clue

Washington, July 18 (IANS) Deepening suspicion that there is or was life in Mars, a study based on images and data captured by the NASA rover Curiosity says that Mars had Earth-like soils comparable with soils in Antarctic Dry Valleys and Chile's Atacama desert some 3.7 billion years ago. Recent images from Curiosity from the impact Gale Crater reveal Earth-like soil profiles with cracked s...

Sharks able to cope with climate change

Washington, July 13 (IANS) Amid fears that climate change may further contribute to already declining population of sharks, a study has found that sharks in the Arctic may be able to cope with the change. The researchers studied the fossil of the sand tiger sharks' teeth found on Banks Island of the Canadian Arctic archipelago. The teeth date back to the Eocene epoch 38 to 53 million...
