Albrecht Dürer Melencolia I detail 

Albrecht Dürer (May 21, 1471 – April 6, 1528) was a German painter, printmaker, mathematician, engraver, and theorist from Nuremberg.  His introduction of classical motifs into Northern art, through his knowledge of Italian artists and German humanists, have secured his reputation as one of the most important figures of the Northern Renaissance. This is reinforced by his theoretical treatises, which involve principles of mathematics, perspective and ideal proportions.His prints established his reputation across Europe when he was still in his twenties, and he has been conventionally regarded as the greatest artist of the Northern Renaissance ever since.

It comes from the 16th-century victims’ teeth.

yellowstone aerial

Beneath Yellowstone National Park lies a supervolcano, a behemoth far more powerful than your average volcano. It has the ability to expel more than 1,000 cubic kilometers of rock and ash at once — 2,500 times more material than erupted from Mount St. Helens in 1980, which killed 57 people. That could blanket most of the United States in a thick layer of ash and even plunge the Earth into a volcanic winter.

 Spinach Leaves and Blood

Researchers face a fundamental challenge as they seek to scale up human tissue regeneration from small lab samples to full-size tissues, bones, even whole organs to implant in people to treat disease or traumatic injuries: how to establish a vascular system that delivers blood deep into the developing tissue.

fire of london monument top 

The Monument is one of London’s most famous landmarks, even giving its name to a local Tube stop. But this tribute to London’s greatest fire also has a secret second use – as a giant piece of scientific equipment. “I’ll just open the hatch...” says Richard Smith, who is stooped over in the ticket office at the Monument. He’s examining the oak-panelled floor as though it’s hiding a secret chamber, as in an Indiana Jones movie. Above him, a desk is piled high with leaflets “This is to certify that "such individual" has climbed the 311 steps of the Monument”. The thing is, there are actually 345.
