  1. Saturn’s Rings Shed Light on Moon FormationWriting in the journal Icarus this week, Prof. Carl Murray from Queen Mary Univ. of London’s Astronomy Unit reports that recently discovered disturbances at the very edge of Saturn’s outer bright A ring result from a small icy object that formed within the ring and which may be in the process of migrating out of it. His team have nicknamed the object, “Peggy.”"We hadn’t seen anything like this before," explains Murray. "We may be looking at the act of birth, where this object is just leaving the rings and heading off to be a moon in its own right."Read more: http://www.laboratoryequipment.com/news/2014/04/saturn%E2%80%99s-rings-shed-light-moon-formation

It gives the director of Michigan Technological Univ.’s Great Lakes Research Center (GLRC) in the cold, snowy Upper Peninsula a chance to do something few others can: study the Great Lakes under a cover of ice.“Our arctic-like environment provides a wonderful opportunity to make the GLRC a true year-round research facility,” Meadows says. This winter, for example, the GLRC built and deployed a cabled observatory under the ice off the research center’s dock, on the Portage Waterway, which connects two parts of Lake Superior.Read more: http://www.laboratoryequipment.com/news/2014/04/observatory-gives-researchers-peek-under-great-lakes-ice

  13. Droplet Find May Aid Ice Prevention, Wing Efficiency

    Those who study hydrophobic materials — water-shedding surfaces such as those found in nature and created in the laboratory — are familiar with a theoretical limit on the time it takes for a water droplet to bounce away from such a surface. But MIT researchers have now found a way to burst through that perceived barrier, reducing the contact time by at least 40 percent.

    Their finding is reported in a paper in the journal Nature co-authored by Kripa Varanasi, the Doherty Associate Professor of Mechanical Engineering at MIT, along with James Bird, a former MIT postdoc who is now an assistant professor of mechanical engineering at Boston Univ., former MIT postdoc Rajeev Dhiman and recent MIT PhD recipient Hyukmin Kwon.

  17. Burning Ice Makes Potable Water from Oil, Gas ProductionIn the midst of an intensifying global water crisis, scientists are reporting development of a more economical way to use one form of the “ice that burns” to turn very salty wastewater from fracking and other oil and gas production methods into water for drinking and irrigation. The study on the method, which removes more than 90 percent of the salt, appears in the journal ACS Sustainable Chemistry & Engineering.Read more: http://www.laboratoryequipment.com/news/2013/08/burning-ice-makes-potable-water-oil-gas-production

Gravity Controls Ice Jets on Saturn’s MoonThe intensity of the jets of water ice and organic particles that shoot out from Saturn’s moon Enceladus depends on the moon’s proximity to the ringed planet, according to data obtained by NASA’s Cassini spacecraft.The finding adds to evidence that a liquid water reservoir or ocean lurks under the icy surface of the moon. This is the first clear observation the bright plume emanating from Enceladus’ south pole varies predictably.

  21. Path of Liquid Water Affects Movement of Glacier

    Supraglacial lakes – bodies of water that collect on the surface of an ice sheet – lubricate the bottom of the sheet when they drain, causing it to flow faster. Differences in how the lakes drain can impact glacial movement’s speed and direction, researchers from The City College of New York (CCNY), Univ. of Cambridge and Los Alamos National Laboratory report in Environmental Research Letters.

    "Knowledge of the draining mechanisms allows us to improve our understanding of how surface melting can impact sea-level rise, not only through the direct contribution of meltwater from the surface, but also through the indirect contribution on the mass loss through ice dynamics," says Marco Tedesco, the principal investigator and lead author.

  23. Arctic Exploration Sheds Light on Future ClimateClimate model projections show that the Arctic Ocean will be completely ice-free by the summer by 2060. However, the record lows in sea ice extent of 2007 and 2012 demonstrated that these projections were too optimistic and some scientists think that we might see an ice free Arctic within this, or the next, decade. This momentous transformation will undoubtedly have important consequences for our climate, but opinions to the extent of the severity of this change vary.In order to put in place timely and effective remedial action however, it is clear that we need to have the tools at hand to accurately monitor and assess exactly what is happening.Read more: http://www.laboratoryequipment.com/news/2013/07/arctic-exploration-sheds-light-future-climate

Researchers Image Subglacial Water SystemIn a development that will help predict potential sea level rise from the Antarctic ice sheet, scientists from The Univ. of Texas at Austin’s Institute for Geophysics have used an innovation in radar analysis to accurately image the vast subglacial water system under West Antarctica’s Thwaites Glacier. They have detected a swamp-like canal system beneath the ice that is several times as large as Florida’s Everglades.The findings, as described this week in the Proceedings of the National Academy of Sciences, use new observational techniques to address long-standing questions about subglacial water under Thwaites, a Florida-sized outlet glacier in the Amundsen Sea Embayment considered a key factor in projections of global sea level rise. On its own, Thwaites contains enough fresh water to raise oceans by about a meter, and it is a critical gateway to the majority of West Antarctica’s potential sea level contribution of about five meters.Read more: http://www.laboratoryequipment.com/news/2013/07/researchers-image-subglacial-water-system
