Maybe goodbye isn’t forever. Get ready to mingle with mammoths and
gaze upon a ground sloth. Scientists want to give some animals a
round-trip ticket back from oblivion. Learn how we might go from scraps
of extinct DNA to creating live
previously-extinct animals, and the man who claims it’s his mission to
repopulate the skies with passenger pigeons.
But even if we have the tools to bring vanished animals back, should we?
Plus, the extinction of our own species: are we engineering the end of humans via our technology?

Think back, way back. Beyond last week or last year … to what was
happening on Earth 100,000 years ago. Or 100 million years ago. It’s
hard to fathom such enormous stretches of time, yet to understand the
evolution of the cosmos – and our place in it – your mind needs to grasp
the deep meaning of eons. Discover techniques for thinking in units of
billions of years, and how the events that unfold over such intervals
have left their mark on you.
Plus: the slow-churning processes that turned four-footed creatures
into the largest marine animals that ever graced the planet and using a
new telescope to travel in time to the birth of the galaxies.
NASA's Kepler mission has discovered two new planetary systems that
include three super-Earth-size planets in the "habitable zone," the
range of distance from a star where the surface temperature of an
orbiting planet might be suitable for liquid water.
ENCORE Just remember this: memory is like
Swiss cheese. Even our recollection of dramatic events that seem to
sear their images directly onto our brain turn out to be riddled with
errors. Discover the reliability of these emotional “flashbulb”
Also, a judge questions the utility of eyewitness testimony in court.
And, don’t blame Google for destroying your powers of recall!
Socrates thought the same thing about the written word.
INCOMING SOLAR STORM: A strong M6-class solar flare on April 11th has
hurled a CME toward Earth. Geomagnetic storms and high-latitude auroras
are possible when the fast-moving cloud reaches our planet on April
13th. Visit http://spaceweather.com for updates.
There are always surprises when we sort through Seth’s wine cellar – who knows what we’ll find!
In this cramped cavern, tucked between boxes of old fuses and a
priceless bottle of 1961 Chateau Palmer Margaux, we discover the next
generation of atomic clock … the key to how solar storms disrupt your
cell phone … nano-gold particles that could make gasoline obsolete … and
what NASA’s Kepler spacecraft has learned about how our solar system
stacks up to others.
Tune in, find out and, help us lift these boxes, will you?
