The United States has debated immigration since the country's founding, and the Statue of Liberty—a potent symbol for immigrants—is often invoked as an argument for why we should usher in those who seek safety and opportunity with open arms. A little-known fact about Lady Liberty adds an intriguing twist to today's debate about refugees from the Muslim world: according to the Smithsonian Institute the statue itself was originally intended to represent a female Egyptian peasant as a Colossus of Rhodes for the Industrial Age. That might be surprising to people more familiar with the statue’s French roots than its Arab ones.
A traditional fountain is an arrangement where water issues from a source, fills a basin of some kind, and is drained away.In fountains sheets of water may flow over varied surfaces of stone, concrete or metal. Basins may overflow from one into another, or the overflow may imitate a natural cascade. Many fountains are located in small, artificial, ornamental ponds, basins and formal garden pools, and often they include sculpture (The "Tab Fountain" in Menorca Spain is shown above).
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.
The face of a modern human is almost uniquely flat and extraordinarily expressive. But our remarkable faces may not be as "modern" as we think. (A reconstruction of a Neanderthal face is illustrated above). These reconstructed faces look impassive, but a range of emotions are painted onto visitors' faces at the Natural History Museum in London.
