World's first x-ray image of a human body part
|
view preview
Wilhelm Conrad Röentgen, a physics professor at the University of Wurburg in Germany, was experimenting with electric current flow in a partially evacuated glass tube in 1895 and one night he noticed a glow caused by an unknown radiation. He named the phenomenon x-radiation and few months later he took the first x-ray photograph of a body part: the bones in his wife’s hand – and one can even see her wedding band. The first even x-ray image was of a key.

Vancouver Island marmots are one of the world's rarest animals
|
view preview
Thanks to deforestation, road building, and other human activity, these sweet little guys have become so rare that in 1997, just 102 Vancouver Island marmots remained in the wild. But conservation efforts have brought them back from the brink, with around 300 captive-bred individuals released into the wild in 2010, and 26 wild litters born last year, producing 80 pups. Researchers state that climate change may further reduce or impact subalpine habitats along with associated forage plants.

|
view preview
This tiny camera invented by scientists F. Levent Degertekin can provide high-definition 3D images of your arteries. The camera, which is the size of an uncooked quinoa grain, uses ultrasound imaging techniques to capture what going on inside the body. The images produced can be used in the surgical theatre, giving doctors a direct view of obstructions in a blood vessel.

Shock-absorbing goo found within bones
|
view preview
A viscous fluid made out of citrate and water is what gives our bones flexibility. The gooey fluid is trapped between the tiny crystals of calcium phosphate that form our bones, absorbing shocks and allowing movement. Without this fluid the crystals fuse together and become less flexible and brittle.
