This GIF shows how the toucan releases heat using its beak to cool itself off.
The toucan beak isn’t just beautiful, it’s also an adjustable thermal radiator that the bird uses to warm and cool itself. When the bird is hot, the blood vessels in their beak open up to allow more circulation to enable heat to escape. Birds can’t sweat so evolution has come up with some life hacks to get the job done.

If you find yourself in Virginia’s Dulles International Airport through November of this year, you might see the exhibition Life: Magnified on the walls. It features scientific images showing cells and other scenes of life magnified by as much as 50,000 times.

Four Bit Maze is an electronic mechanical puzzle that is 100% tactile.
The object of the puzzle is to move all four sliders from the “0” position to the “1” position. Each challenge has only 16 binary states, and the operation of each challenge is 100% deterministic without any hidden states. Some challenges are easy and playful,whereas others are fiendishly hard.
Scientists have turned brown butterfly wings purple in just six generations through selective breeding. This experiment will help scientists understand the nanoscale structures responsible for the colour of butterfly wings: http://bit.ly/1kQzKGh via Phys.org
This working model of a Stephenson steam engine is handcrafted entirely from glass by Czech artist Michal Zahradník. The artist says the engine can operate at up to 500 rpm. All component parts, such as the crankshaft and the piston, are made of glass. Even the counterweight that makes the wheel spin evenly is glass. No sealants were used, all is accomplished by a perfectly precise snug fit. The gap between the piston and its compartment is so small, that the water that condensates from the steam seals it shut. Notice the elaborate excessive steam exhaust system next to the piston. The piston is the most arduous part to make due to to the extreme level of precision needed. The piston and its cylinder must be hand sanded to perfection, and often crack in the process.

The Theory of Everything is an upcoming 2014 British biopic-drama based on the life of physicist Stephen Hawking. It stars Eddie Redmayne as Hawking and Felicity Jones as his wife Jane and chronicles their relationship, from his early development of ALS to his success in physics.
There’s not much to say about this other than how ridiculously fantastic this film is going to be and that I’m amped to see it. Amidst a society where the “heroes” placed atop the proverbial pedestal of success and achievement are passed along as sports figures, pop-culture feeding pseudo-celebrities, obnoxious and anti-intellectual TV personalities, or gun-toting action film actors (among others), there couldn’t be a better time for a film like this to enter the media sphere.
