They call it "Muufri".In order to study penguins up close, without disturbing them, researchers from Centre National de la Recherche Scientifique used small baby-penguin sized rovers. The rover - cleverly disguised as a penguin - was able to monitor penguins and even quick-tempered elephant seals without alarming the animals.A man who had brain surgery for a serious medical […]

3:01 PM | How Likely Is It That Birth Control Could Let You Down?
Which form of birth control a woman takes is far more complicated than simply how effective that form is. But effectiveness is certainly an important thing to consider. I love how this visualization shows all the options together in a really easy to read set of graphs. Roll over through time to see the number of women (for every 100) who will have an unplanned pregnancy using each method. » Rose

9:01 PM | The Infinite Golden Record
We love Lily Bui’s work (we even had her on as a guest picker here recently!) and this most recent bit of magic is no exception. You might know that NASA’s Voyager is carrying two golden records with it, to show any alien civilizations what we humans sound like and care about. Now you can listen to those records, infinitely! Bui set up a site that plays the tracks from the records for you on a loop.  Bui explains a bit more about the background for the project here. […]

8:56 PM | Earth View from Google Maps
Okay, so, this is a weird one. But I think it’s really cool so hear me out. This is a Chrome extension. It’s called Earth View from Google Maps, which is pretty self explanatory. The premise is this: Every time you open up a new tab in Chrome, instead of seeing a blank white page, you see an image from Google Earth. This seems simple, and it really is, but it has made my internet usage incredibly more pleasurable.  Allow me to wax poetic about this for a moment longer. […]
