"For me science isn't a subject, it's a perspective. There are fascinating scientific aspects to everything from ancient history to the latest gadgets, outer space to interior decorating; and each week on The Material World we try to reflect the excitement, ideas, uncertainties, collisions and collaborations as science continues its never-ending voyage into the unknown".

| George, the last Geochelone nigra abingdoni |
Lonesome George
A Galapagos Islands giant tortoise, nicknamed Lonesome George, is the last of his sub-species known to exist.
In 1972, George was taken to the Charles Darwin Research Station in an effort to breed him with closely related species, but these efforts have so far been unsuccessful.
This week, Quentin Cooper is joined by Professor William Holt, of the Institute of Zoology, and Dr Henry Nicholls, author of the book Lonesome George,听to discuss preserving the genetic diversity of rare animals.听
Mega Plumes
In 1986, a small research vessel discovered a huge hydrothermal system off the Juan de Fuca ridge in the Northern Pacific.
This newly discovered phenomenon, the mega plume, is defined by the sheer magnitude of water and heat it contains and is thought to be the initial belch preceding the formation of a hydrothermal vent.
Last year in the Indian Ocean, another enormous mega plume, four times the size of any other ever recorded, was discovered.
Dr Bramley Murton and Dr Jon Copley of the National Oceanography Centre, Southampton, talk to Quentin about the fact and fiction of mega plumes. |
