Let’s be real, if Kevin pulled off the traps and stunts he did in Home Alone in real life, there would be no movie, because the Wet Bandits would be deader than dead. Torching a scalp, smashing a head with a can of paint, beating up a chest with a crowbar, all those scenes would end up with a lot of gore and someone…

Sticking your arm inside a box of mosquitoes to get bit is very probably the most fearless thing a person on this planet can do. It’s also very probably the dumbest thing in the world to do because you’ll end up with over 30 itchy mosquito bites that’ll make you want to rip the skin off your arm.

The holidays are all about celebrating life—yet there’s nothing more thrilling than watching this simulation of 11,000 penguins and 4,000 Santa Clauses fighting to the death.

Blood isn’t supposed to plop out like a solid like that but that’s what happens when a snake’s hemotoxic venom gets mixed in with human blood, it thickens liquid blood into this congealed jelly substance. It’s pretty gross. But this is how a venomous snakebite affects the body of its prey, a lot of tiny blood clots…

The next time someone refers to a horror movie as “bloodcurdling,” they might actually be kinda right. A new study shows that the fear experienced when watching scary movies is in fact associated with an increase in clotting agents in the blood.

A new ultrasound technique that uses tiny micro-bubbles to help improve the contrast of its images is capable of producing highly detailed pictures of blood vessels inside living animals.

Blood. It’s not something you want to see more than you have to, but at the same time, it’s a miraculous substance, fueling both mankind’s daily exploits, and a full genre of YA fiction. For this week’s Shooting Challenge, we asked you to photograph it.
