Indians are facing shortages of clean water across the country as groundwater supplies shrink, and the crisis is particularly severe in Chennai. The struggle for solutions is pitting municipal governments against private water carriers.
In a wildlife sanctuary in Plymouth, Mass., wireless sensors, cameras, and microphones pick up every sound and movement. Researchers hope to use the data to both better understand changing climates and help power a virtual reality world.
Syrian refugees in Jordan are working alongside their neighbors to retrofit homes with solar-thermal water heaters, shading devices, and rainwater collection tanks. 'We made friendships and became a community through work,' says one Jordanian.

Xu Xing, a "superstar" paleontologist who has named more dinosaur species than any other living scientist, is leading a dig in a fossil-rich area of China that is uncovering links between birds and dinosaurs. The area was discovered accidentally through a construction project.
A glacier in China – and a highly visited tourist destination – has lost 60 percent of its mass and shrunk 250 meters since 1982, researchers say.
Depending on whom you ask, fracking has either been a boon for or a scourge on the United States. In Colorado, both visions have played out. And this November, the two perspectives face off on the ballot.
Low pressure, lack of wind shear to drive it back, and warmer than normal Gulf waters combined to allow hurricane Michael to reach its full potential as a Category 4 hurricane. Scientists say global warming will continue to increase the rapid intensification of tropical weather.
