It's true! Science proves it!
And it's more than just an effect of infrared imaging. If you duck over to Joseph Stromberg's post at the Surprising Science blog, you'll see a photo of a real, live reindeer with an adorably red nose (and upper lip).
Turns out, it's the result of an evolutionary adaptation. Some (but not all) reindeer have noses full of densely packed blood vessels — a difference that makes those reindeer better at regulating their own body temperatures.
To come to the findings, the scientists examined the noses of two reindeer and five human volunteers with a hand-held video microscope that allowed them to see individual blood vessels and the flow of blood in real time. They discovered that the reindeer had a 25% higher concentration of blood vessels in their noses, on average.
They also put the reindeer on a treadmill and used infrared imaging to measure what parts of their bodies shed the most heat after exercise. The nose, along with the hind legs, reached temperatures as high as 75°F—relatively hot for a reindeer—indicating that one of the main functions of all this blood flow is to help regulate temperature, bringing large volumes of blood close to the surface when the animals are overheated, so its heat can radiate out into the air.
Also: red-nosed reindeer on treadmills, you guys. This is clearly the most adorable science of the holiday season.

SmarterEveryDay’s Destin Sandlin captured this astonishing video of the International Space Station transiting Monday’s solar eclipse. Fast forward to 3:50 for the magical moment. And in case you missed it, below is NASA’s still photo of the ISS transiting the sun at five miles per second.
The psilocybin in magic mushrooms is a potent psychedelic for animals. But what good is the psilocybin for the shrooms? New genetic research from Ohio State University suggests that the psilocybin might act as an insect repellant, protecting the mushrooms. From New Scientist: The gene cluster (linked to psilocybin production) is found in several distantly […]
In elementary school, I knew a boy who would impress us by pulling the legs off a daddy longlegs and popping the body in his mouth. I think he would appreciate this Deep Look video about how daddy longlegs can drop up to three of its limbs when threatened by a predator and still survive.
