The Pennsylvania Game Commission’s Bureau of Wildlife Management is recommending the bald eagle be upgraded from “threatened” to “protected” status statewide. This year, biologists have confirmed 266 nesting pairs across Pennsylvania.
Observed in the wild, tucked away in museum collections, and even exhibited in zoos around the world―there is one mysterious creature that has been a victim of mistaken identity for more than 100 years. A team of Smithsonian scientists, however, uncovered overlooked museum specimens of this remarkable animal, which took them on a journey from museum cabinets in Chicago to cloud forests in South America to genetics labs in Washington, D.C. The result: the olinguito (Bassaricyon neblina)―the first carnivore species to be discovered in the American continents in 35 years. The team’s discovery is published in the Aug. 15 issue of the journal ZooKeys.
A 60-foot-wide sinkhole formed under a resort in central Florida late Sunday, August 11, forcing guests out of their rooms as one three-story building collapsed and another slowly sank. Check out these links to learn more about this specific event and about sinkholes in general.
From the National Science Foundation - A University of South Florida team are using the "flesh" from Prickly Pear cacti, called mucilage, to clean up oil and other toxins from water. The objectives of this research are to develop a water purification system based on an economically feasible method for low-income inhabitants of rural communities that are sensitive to existing economic, social and cultural patterns.
Something big is about to happen on the sun. According to measurements from NASA-supported observatories, the sun's vast magnetic field is about to flip. "It looks like we're no more than 3 to 4 months away from a complete field reversal," says solar physicist Todd Hoeksema of Stanford University. "This change will have ripple effects throughout the solar system."
The Curiosity rover is seeking environments on Mars that could support life—or could have in the past. Earlier Mars missions found signs of water, but not organic carbon—life's essential building block. Watch the Curiosity team prepare to hunt for carbon at Mount Sharp, which holds a geologic record hundreds of millions of years old.

The Paluweh Volcano, also referred to as the Rokatenda Volcano, has been busy since late 2012. This stratovolcano, located in Indonesia, just erupted in early August of 2013, killing at least five people. Unfortunately, many news media outlets are characterizing the most recent eruption as a lava flow, which is scientifically inaccurate. The eruptive behavior is that of a pyroclastic flow.
