A number of breakthrough studies are beginning to paint a picture of how these wonders of the world were built, but much of the story still remains a mystery...How the Egyptian pyramids were built has long been a mystery. Constructed as tombs for the pharaohs over 4,000 years ago, more than 100 of them remain. The largest one, the Great Pyramid of Giza, was originally 147m tall (482ft). It's made up of about 2.3 million stone blocks, each weighing between 2.5 and 15 tonnes, and would have had to be transported to the building site and lifted into place with techniques available at the time. To put this into context, it's akin to lifting a double-decker London bus to the top of St Pauls Cathedral a few million times.

An Artificial Heart Inspired by Plumbing - Mechanical circulation could revolutionise transplant design and reduce waiting lists

Mechanical circulation could revolutionise transplant design and reduce waiting lists. In July, this artificial heart was successfully implanted, for the first time, into a patient with end-stage heart failure. Built by The Texas Heart Institute (THI) and BiVACOR, the replacement organ has been dubbed the Total Artificial Heart (TAH). Although, being an implant rather than transplant, it's designed to temporarily support patients while they wait for a real heart transplant.
