That's the number of minutes that Amazon executive Paul Misener said the online giant was targeting as the upper end of its drone delivery capabilities from time of order, during testimony in front of a House committee in Washington looking into drone regulations. "If a consumer wants a small item quickly, instead of driving to go shopping or causing delivery automobiles to come to her home or office, a small, electrically-powered [drone] vehicle will make the trip faster and more efficiently and cleanly," Misener said. Amazon and others are hoping Congress will pass laws that making drone delivery testing and ultimately commercialization easier than recent rules from the FAA, which all but make even testing near impossible.

The number of major global underground water sources out of a total of 37 aquifers analyzed that have passed their "sustainability tipping points," according to data release this week from a study led by the University of California Irvin, based on NASA satellite data. Passing the tipping point means more water was removed from the aquifer than was replaced during the decade-long study period, the researchers said. In addition, 13 of the 37 total aquifers studied in locations from India and China to the United States and France declined at rates that put them into the most troubled category. "The situation is quite critical," said Jay Famiglietti, senior water scientist at NASA's Jet Propulsion Laboratory. Underground aquifers supply 35% of the water used by humans worldwide, and more during times of drought. Some, however, think the warnings are overblown, noting that the NASA satellites could not measure the total capacity of the aquifers. Still, "water is the new oil" likely could be right.
