Spies used them first, then the Air Force, then cops, then mischievous civilians; drones, for some reason, are what gawkers use to gawk. They're spy accessories. But not only spy accessories. Thanks to Jasper van Loenen, drones are about to expand their repertoire. The word "drone" is about to become a verb, as in "Drone it to me"...
Being a wildlife biologist in the 21st century increasingly means rescuing rare animals from extinction. Among the success stories is the whooping crane. Seventy years ago there were only about 16 birds left on the planet. Now there are about 600.
Here's a sound you'd rather not hear out on a hike.

If you're finding it harder to remember where you put the car keys, the culprit could be a brain protein with a name that's easy to forget: RbAp48.
A shortage of this protein appears to impair our ability to remember things as we age, researchers report in the current issue of Science Translational Medicine. And boosting levels of RbAP48 in aging brains can reverse memory loss, at least in mice, they say.

There's no question that dealing with mortgages, car payments and other bills takes up time and energy. But having a tight budget may also zap our ability to think clearly, scientists report Thursday in the journal Science.

A children's adventure garden, a $62 million education center focused on earth and life sciences, is about to open in Texas at the Dallas Arboretum. Maria Conroy, the Arboretum's vice president and the driving force behind the garden, told The New York Times last week that, because Dallas is an urban jungle without much green space, some children there are afraid of nature:
It's not news that Hong Kong, which brags one of the world's most stunning skylines, has been gradually losing it behind a curtain of smog.
But the Chinese territory's latest solution is new: To placate camera-clicking tourists unable to get those iconic shots of the skyscraper-studded waterfront, Hong Kong has set up a panoramic backdrop with clear, blue skies.
The Chinese website Netease published a series of pictures of tourists posing in front of the backdrop.
