We all want to turn back time. But until we build a time machine, we’ll have to rely on a few creative approaches to capturing things as they were – and preserving them for posterity. One is upping memory storage capacity itself. Discover just how much of the past we can cram into our future archives, and whether going digital has made it all vulnerable to erasure.

Plus – scratch it and tear it – then watch this eerily-smart material revert to its undamaged self. And, what was life like pre-digital technology? We can’t remember, but one writer knows; he’s living life circa 1993 (hint: no cell phone).

Also, using stem cells to save the white rhino and other endangered species. And, the arrow of time itself – could it possibly run backwards in another universe?
