Some 900 million miles from the Sun in the outer regions of our Solar System orbiting the planet Saturnlies a mysterious world. Enceladus is enveloped in ice. Because nearly all of the sunlight that manages to hit its surface is reflected back into space, its one of the brightest objects in the solar system. ... Full story

London, Mar 27 (ANI): The eerie image of a figure captured in a photograph at a Scottish castle is said to have left ghost experts baffled. The picture clicked in May last year shows a spectral figure in fifteenth century dress peering out of a barred window at Tantallon Castle in Fife. As the castle does not use any mannequins or costumed guides, experts are puzzled with ... Full story

Washington, March 26 (ANI): In a new research, scientists have determined that as soot particles in the atmosphere age, airborne sulfuric acid may help turn them into condensation nuclei, which enable the formation of clouds. The research was conducted by Alexei F. Khalizov and colleagues from Texas A and M University, who worked alongside researchers from University ... Full story

Ladakh, Mar 12 (ANI): Farmers in Ladakh have taken to greenhouses, overcoming the hazards of harsh winters in a novel way. Over 90 per cent of Ladakh's population is dependent on agriculture. But very short summers and long winters make it hard for farmers to grow vegetables even to sustain themselves. They now farm in greenhouses, ensuring availability of vegetables throughout the year. Farmers say that the main ... Full story

Melbourne, March 10 (ANI): A pink dolphin has been pulling in crowds in Louisiana after being spotted in Lake Calcasieu. "Pinky", thought to be the world's only pink dolphin, was said to have reddish eyes and was usually seen with its dark grey mother. Boat captain Erik Rue, aged 42, had first spotted the unique bottlenose in 2007, and claims it "looks like it just came ... Full story

Washington, March 4 (ANI): A new study has shown that the emission of water, carbon dioxide (CO2) and methane from small volcanic vents near the rim of the 19,850-foot-high Socompa volcano in the Andes Mountains, is helping to sustain complex microbial ecosystems. The study, by ... Full story

Washington, Feb 28 (ANI): A team of scientists at Penn State University has come up with an ingenious method of turning captured CO2 into methane, a combustible fuel, using the energy of the sun. The team, led by Craig Grimes, described a highly efficient photocatalyst ... Full story

London, Feb 24 (ANI): NASA's new climate-monitoring satellite, the Orbiting Carbon Observatory (OCO), which would pinpoint sources and sinks of carbon dioxide (CO2), will blast off today from California's Vandenberg Air Force Base. According to a report in New Scientist, with the help of the satellite, scientists will be one step closer to understanding how some CO2 ends up building a dangerous greenhouse above our heads, ...

London, Feb 12 (ANI): Astronomers have claimed that swathes of dark comets may e prowling the solar system, posing a deadly threat to Earth. According to a report in New Scientist, UK-based astronomers Bill Napier at Cardiff University and David Asher at Armagh Observatory in Northern Ireland have made the claim that many such comets could be going undetected. "There is a case to be made ... Full story

Washington, Feb 10 (ANI): Ever wondered why we catch flu mostly in the winters? Well, Oregon researchers claim to have found the answer. They have found that influenza virus survives and travels best when "absolute" humidity is low. According to lead author Jeffrey Shaman, an Oregon State University, It has long been suspected that there is a link between humidity and flu transmission and prevalence; however, these ...

London, February 6 (ANI): Materials scientists at Pennsylvania State University in University Park have successfully used sunlight to convert carbon dioxide and water vapour into a range of fuels faster than ever before. Lead researcher Craig Grimes has revealed that his team used hollow titania (titanium dioxide) nanotubes-around 135 nanometres wide and a tenth of a millimetre long-to catalyse the reaction. Though titania nanoparticles have been ... Full story

Washington, Feb 6 (ANI): In a new research, scientists have determined that geologic features in Martian craters suggest deposition and flow of water and ice, which is further evidence for the large role that water has likely played in shaping the landscape of the Red Planet. The research was done by scientists at the Tucson-based Planetary Science Institute (PSI) in the US. Their results provide strong evidence ... Full story
