In the Southern Hemisphere, the ice cover around Antarctica gradually expands from March to October each year. During this time the total ice area increases by 6 times to become larger than Russia. The sea ice then retreats at a faster pace, most dramatically around December, when Antarctica experiences constant daylight. New research led by the University of Washington explains why the ice retreats so quickly: Unlike other aspects of its behavior, Antarctic sea ice is just following simple rules of physics. The study was published March 28 in Nature Geoscience. A research vessel in Antarctica on June 3, 2017, the first day researchers saw the sun rise above the horizon after weeks of polar darkness. New research shows that solar radiation drives the relatively fast annual retrea...

Mexican scientists have developed a unique "nanobubble" system using solar energy to improve water quality in the canals of Mexico City's Xochimilco ecological zone, a popular tourist attraction. Officials in Mexico City have been focused on cleaning up the long-polluted waters of Xochimilco, a UNESCO World Heritage Site and one of the few areas of the capital that still boasts canal networks dating back to Aztec times. Members of a team of researchers from the Center for Research and Advanced Studies (Cinvestav), who developed a method that converts solar energy into photovoltaic energy that activates a pump that sends "nanobubbles" into the water, install a water system at a trajinera boat as part of a project to clean the polluted waters at the canals of Xochimilco, in Mexico Cit...
