In 1915, workers cutting peat in a Denmark bog discovered the skeletal remains of a man. They uncovered the right anklebone, lower left shinbone, jawbone and a fragmented skull, along with a wooden club, a ceramic vessel and cow bones. Scientists eventually determined that the remains were those of a man who lived and died about 5,200 years ago. He was given the name Vittrup Man, and scientists think he was killed by blows to the head between 3100 BC and 3300 BC. ... More » }

The brain is perhaps our most mysterious and complex organ. Its structure is unique, and its chemical composition is much different from our other organs. One tool being refined in helping us understand the brain is growing tiny brains called organoids. Stem cells are coaxed into forming these pea-sized structures that then allow us to study it. ...
