Pouring small amount of liquid nitrogen into your hand won’t hurt, as long as you get a few seconds of recovery time between pours. Please don’t try this at home.

My grandmother recently went through Bypass surgery. Her surgery was successful and she is currently in the recovery phase. I read more about Bypass surgery and here is what I found:

Bypass Surgery

When an artery leading from the heart becomes clogged with plaque — material composed of cholesterol and fats that form and harden inside blood vessels — the heart can’t receive all of the blood that it needs. This can cause a heart attack, and in fact, my grandmother suffered a mild heart attack and was rushed to the hospital. 

Bypass surgery involves taking a piece of a healthy blood vessel from elsewhere in the body and grafting, or attaching, it to the damaged vessel. In doing so, the blood flow is rerouted around the damaged part. (Source)

Using a new technique that is 10x faster than average MRI scanners, researchers at the Beckman Institute for Advanced Science and Technology show how the muscles in our neck, jaw, tongue, and lips work together to create sound.

Cordyceps Fungus

body, finally causing its death. White tubes emerge to spread the spores,
which then infect other butterflies. Madidi National Park, Bolivia (Source)

An MRI of Cracking Joints

The video above shows a subject pulling his finger in an MRI. Our joints are lubed with what’s called synovial fluid, and when you crack your knuckles, your joints separate and create more space. Essentially, there’s not enough of that fluid to fill the gap. Therefore the gas-filled above appears and is behind the sound that you hear.

Distance to Mars

Ever wondered how far it is to Mars? Yes, I know that Wikipedia can tell you the exact distance, but once numbers become, well, astronomical, it can be difficult to really wrap your head around them. To help you out, David Paliwoda and Jesse Williams’s motion infographic, Distance to Mars visualizes these massive distances in a way that every digital designer can understand – in pixels!
