Egyptian animal mummies can glance like little much more than bundles of cloth. Now superior-tech X-rays have unveiled the mysterious everyday living histories of three of these mummies — a cat, a chook and a snake.

Although 2-D X-rays of every single specimen existed, minimal info existed past generic animal labels. So Richard Johnston, an engineer at Swansea University in Wales, and his colleagues applied a microCT scanner to see what lies beneath the wraps of animal mummies at the university’s Museum of Egyptian Antiquities.

The mummified cat’s head (observed in this 3-D design created from microCT information) was divided

Historical sculptures hint at common facial expressions

Faces depicted in sculptures crafted in between 3,500 and 600 a long time back in Mexico and Central America convey 5 varieties of emotion to Westerners currently, say computational neuroscientist Alan Cowen and psychologist Dacher Keltner, both of those of the College of California, Berkeley. Existing-day folks, and probably members of historic American societies as well, anticipate that every single of these emotional expressions takes place in certain social scenarios, the experts report August
