EEEEEEEE EEEEEEEEE EEEEEEE

That's right! It's International Bat Appreciation Day! We share our planet with over 1400 species of bat, making the second most abundant mammal order, and they perform a wide variety of ecological roles, from dispersing seeds to pollinating flowers to eating thousands of insects in a single night! Over 200 bat species are listed as Threatened by the International Union for the Conservation of Nature--that is over 14 percent of all bats!

YOU can help endangered bats today by donating to Pennsylvania Bat Rescue at this link. This PA-based organization rehabilitates sick or injured bats and helps educate people like you and me in how we can create more bat-friendly environments.

If you want to learn about particularly-cool bat species native to New Zealand, check out this Consider Nature article on the Pekapeka, the bat that walks:

For the rest of the day, Consider Nature will be bat-bombing Tumblr with some of our favorite bat species to share them with the world!

Mimicking Plant Movement

Many plants control the curvature of their leaves by selectively pumping water into cells that line the outer surface. This swelling triggers bending. Engineers created their own version of this structure. (Image credit: T. Gao et al.; via GoSM) Read the full article

HiPOD: The Dunes of Change

The Mars Orbiter Camera imaged these dunes in 2000, so now we can learn what a multi-decade dune movement average is by taking a new observation to create a MOC-HiRISE temporal pair. With MOC providing a long baseline to newer HiRISE images, we can build up global averages of the effects of wind on the environment. Two decades is long enough that the dunes will have moved noticeably between MOC and HiRISE. (Grayscale cutout is less than 5 km across; enhanced color is less than 1 km.)

This black and white photograph shows two men in a room of 1950’s computer equipment, with many dials and cables everywhere.  One man is standing and appears to be adjusting the equipment, while the other is sitting at a desk looking at a large binder and making notes.

The way flat earthers claim that the earth is so obviously flat just baffle me. Like, do you people even watch the sky?

If the earth was actually flat and the sun was a flat disk as many claim, the sun would appear to get flatter as it reached the horizon.

If the earth was actually flat, contrails wouldn't curve downward on the horizon. Clouds wouldn't obviously be curving. Satellites wouldn't obviously be taking a curved path.

The earth is just... so obviously round if you actually pay attention to the sky????

Banana Bat (Musonycteris harrisoni)

Vulnerable

- This bat eats exclusively nectar, with its long schnoz helping it to get into the nooks and crannies of flowers.

- Yes I am aware that you are not supposed to touch bats and I do not know why this photographer is doing so.
