Stereo, or 3D, vision is what enables humans to gauge the depth and distance of surrounding objects. The right and left eye capture slightly different images and send them to the brain, which merges them and then calculates the proximity of everything in the vicinity. The ability, which requires an intricate network of neurons and lots of processing power, can also be found in a select group of animals like cats, horses, owls and sheep, as well as one insect — the praying mantis....

In mid-January, Cape Town officials announced that the world-class South African city of four million residents would run out of water on April 12. The date, nicknamed “Day Zero,” has since been postponed multiple times, thanks to the intense conservation efforts by locals, a sharp reduction in agricultural water usage, and a 10 billion-liter donation from the private reservoirs of the Groenland Farmers Association. The city now has enough water to sustain the current level of usage until July 9, giving residents hope that the rainy season, which begins in June, will be more normal than has been the case lately....
