'Artificial blubber' to protect divers in icy water: Here's how 21.6.2018 DNA: Wide Angle
Scientists have created wetsuits with 'artificial blubber' that can keep deep sea divers warm in icy cold water. When rescue teams are diving under ice-covered rivers or ponds, the survival time even in the best wetsuits is very limited - as little as tens of minutes, and the experience can be extremely painful at best. Researchers from Massachusetts Institute of Technology (MIT) and George Mason University in the US developed a simple treatment that can improve the survival time for a conventional wetsuit by a factor of three. The process works by simply placing the standard neoprene wetsuit inside a pressure tank autoclave no bigger than a beer keg, filled with a heavy inert gas, for about a day. The treatment then lasts for about 20 hours, far longer than anyone would spend on a dive, said Jacopo Buongiorno, professor at MIT. The process could also be done in advance, with the wetsuit placed in a sealed bag to be opened just before use, he said. Researchers looked at the different strategies that ...

Gujarat fishermen can earn 8-fold through 'cage culture' 16.6.2018 DNA: Top News
A new fishing technique that was developed by scientists from the Gujarat Institute of Desert Ecology (GUIDE) has yielded eight-fold returns in fishing under a trial conducted in the past 8 months. Come monsoon, the fish cage culture will now be actively adopted by over 500 fishermen across the state. The cage, built with bamboo, drum and barrel, costs between Rs 15,000 to Rs 25,000 with a life of four to five years inwater. What is the cage culture? Fishes are raised commercially in one of four culture settings — open ponds, raceways, tanks, or cages. The cage culture utilizes existing water resources but encloses the fishes in a cage or basket, which allows water to pass freely between the fish and the pond. "In this technique, a floating structure with enclosed fishnets, synthetic ropes, buoys, and anchors is installed in open sea or estuary, which is used for culturing fishes, shrimps and crabs. We have experimented for milkfish," said Vijay Kumar, Director, GUIDE. "The cage culture provides high ...

Environmental emergency in Bellandur lake, not even 1 ml of clean water available, NGT informed 14.6.2018 DNA: Top News
 Indiscriminate discharge of untreated sewage into Bengaluru's Bellandur lake has resulted in an "environmental emergency", a committee has told the National Green Tribunal, adding that there is not even one millilitre of clean water in the lake. The NGT-mandated committee said the biggest lake of the beautiful city of Bengaluru had become the largest septic tank of the city due to "sheer callousness and indifference" of the authorities. "According to the material collected, the water holding capacity of Bellandur lake has rapidly shrunk due to indiscriminate dumping of construction and demolition waste, municipal solid waste and due to vast spread of hydrophyte and microphytes in the lake water. Hydrophytes are aquatic plants that grow in or near water and provides cover for fish and other aquatic organisms. "The commission during the inspection was shocked to notice a road that has been constructed on the Varthur lake by dumping construction and demolition waste under the garb of laying a pipeline," ...

A special commission that has been set up by the National Green Tribunal (NGT) to inspect Bengaluru’s lakes slammed the Karnataka government saying that it had ‘miserably failed to discharge their obligations to the society and their duties,’ India Today reported. “The biggest lake of the beautiful city of Bengaluru by sheer callousness and indifference of the authorities has become the largest septic tank of the city," the commission stated in its report.  Last February, the Union Ministry for Environment had ordered an inquiry into a fire that had broken out in the garbage strewn around Bellandur lake. Due to several reasons, the main being dumping of construction waste and municipal solid waste, along with the spreads of hydrophytes (underwater plants) and microphytes, the lake’s water holding capacity has reduced. Commission members also pointed out that the storm water drain outlets near the lake were discharging sewage and industrial effluents, which in turn were released into the lake.  The report ...
