Most nectar-feeding animals evolve special quirks (mainly of the tongue) that optimize their eating habits.
But for the groove-tongued bat (Lonchophylla robusta), evolution has dealt a bit of a strange hand. Instead of lapping up or siphoning liquid as other mammals do, this bat hovers over its food source and dips its long, slender tongue into the nectar, keeping contact the entire time it drinks.
Researchers filmed the bat with a high-speed video camera to try to decipher the special tongue mechanism, and watched as the fluid flowed upward along the bat’s tongue, against gravity, and into its mouth.
Today, researchers report in Science Advances that the conveyor belt–like mechanism may actually allow these bats to feed more efficiently from certain types of flowers…

Flying 250 miles above the Earth aboard the International Space Station has given me the unique vantage point from which to view our planet. Spending a year in space has given me the unique opportunity to see a wide range of spectacular storm systems in space and on Earth.
The recent blizzard was remarkably visible from space. I took several photos of the first big storm system on Earth of year 2016 as it moved across the East Coast, Chicago and Washington D.C. Since my time here on the space station began in March 2015, I’ve been able to capture an array of storms on Earth and in space, ranging from hurricanes and dust storms to solar storms and most recently a rare thunder snowstorm.

Sturlesi Design creates modern lamps that are simultaneously practical home decor and art objects. Their minimalist design reimagines animals as angular, geometric shapes, with LED lights hidden in their concrete bases. When not in use, these devices look like tiny statues—you’d never realize they’re powerful lamps. See more in the Sturlesi Design Etsy shop.

reindeer are the only mammals whose eyes are known to change colour, going from a gold in the summer, when the sun is a constant presence in the arctic, to a less reflective blue in the near perpetually dark winter months.
in dark conditions, muscles in your irises contract to dilate your pupils and allow more light into your eyes. when it’s bright again, the irises widen and the pupils shrink. the same thing happens in reindeer, but the arctic winter forces their pupils dilate for months at a time.
this constant effort to stay dilated ends up blocking the small vessels that drain fluid out of the eyes, which causes pressure to build up. this in turn compresses the collagen fibers that make up tapetum - a mirrored layer that sits behind the retina (seen in the second photo).
when compressed, these fibers in the eye reflect blue wavelengths of lights instead of the yellow which accompanies a typical spacing of the fibers, as in summer. (photos x, x)
