A study by Chinese and U.S. scientists finds that while populations of the iconic giant panda have increased recently, the species' habitat still covers less area and is more fragmented than when it was first listed as an endangered species in 1988.

The study, published Sept. 25 in the peer-reviewed journal Nature Ecology and Evolution, used geospatial technologies and remote sensing data to map recent land-use changes and the development of roads within the panda's habitat.

Sand, spanning miles of beaches, carpeting vast oceans and deserts, is a visual metaphor for limitless resources. Yet researchers in this week’s journal Science seize another metaphor –  sand in an hourglass, marking time running out.

Sand is the literal foundation of urban development across the globe, a key ingredient of concrete, asphalt, glass, and electronics. It is cheap and easily extracted. Scientists in the United States and Germany say that easy access has bred a careless understanding of the true global costs of sand mining and consumption.
