Big Picture Science for Monday 22 September 2014 - As You Were

Big Picture Science - As You Were

ENCORE: 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?

Big Picture Science - No Expiration Date

ENCORE: We all have to go sometime, and that final hour is the mother of all deadlines. But scientists are working to file an extension. Discover how far we can push the human expiration date.

Plus, the animal with the shortest lifespan and the chemistry that causes your pot-roast to eventually clothe itself in fuzzy green mold.

Also, a clock that won’t stop ticking (for 10,000 years) and our love-hate relationship with that long-lived hydrocarbon that keeps our snack cakes fresh: plastic!
