Growing New Organs
Can We Live Forever? Growing New Organs
Have you ever wondered if we could replace old worn body parts much like you’d replace parts on your car? Well, that time is nearly here and the possibility of greatly lengthening lifespan may be just around the corner. New discoveries in the scientific community are quickly advancing the ability to not only replace organs, but grow them from a patients own unique cells. This episode from NOVA reveals some of the unusual techniques that have allowed scientists to create the structures necessary for new ears, lungs and even hearts while showing us that the day of rejected donor organs and long recovery periods may well be gone.
Libya's Foreign Minister 'Defects To UK'

Here, a brief guide:
Rare dinosaur found in Canada's oil sands
TORONTO, Mar. 25, 2011 (Reuters) — The Canadian oil sands, a vast expanse of tar and sand being mined for crude oil, yielded treasure of another kind this week when an oil company worker unearthed a 110-million-year-old dinosaur fossil that wasn't supposed to be there.
The fossil is an ankylosaur, a plant-eating dinosaur with powerful limbs, armor plating and a club-like tail. Finding it in this region of northern Alberta was a surprise because millions of years ago the area was covered by water.
