Deep in the heart of the African rainforest, rightists have made a

remarkable discovery. A huge area of swampland in the Republic of Congo.

At 2000 -- 200,000 square metres, it's bigger than the whole of

England and debris than an Olympics remain cool. But the discovery

wasn't easy. The scientists had to watch out for crocodiles, gorillas

and elephants. It was incredibly surprising to find an area the size

of England that, essentially, was uncharted. We walked through it in

the daytime collecting our samples. In the evening, we put up tents. The

land is special because it contains tonnes of decay which is more than a

thousand years old. Pete is all around us. This peatland in Greater

Manchester is quite wet and spongy. On the surface, it doesn't -- it is

spongy on the surface. It is incredibly important for

conservation because all of this has been slowly decomposing the more

than 12,000 years. Via mac it's a living history that records

everything that has happened in the area. They've got things like

elephants, crocodiles. Things we don't have here. They've also got

trees. Scientists have brought back samples of the Pete to test. It will

help them learn more about how the environment has changed over the

last thousand years. In Ukraine there's been

serious fighting at an airport Armed groups who want Russia to have

more of a say in how the country's run clashed with the Ukrainian army

Thames Tunnel - built over 250 years Back in Victorian London,

people needed a new way to get across the crowded River Thames

so an engineer called Marc Brunel suggested building a tunnel

between Rotherhithe and Wapping. This was the dream- but no one had

ever successfully built an underwater tunnel before- and

working on it was very dangerous. workers in cells,

they do two hour shifts. Work began in 1825

and took 18 years to complete. Workers would work in shifts but

they had to come off after a couple of hours because of the air

pressure. Work began in 1825

and took 18 years to complete. 50,000 people came to the grand

opening and it became a major tourist attraction as people flocked

to pass under the Thames, and visit the underground shops that were set

up in the tunnel's archways. But the novelty wore off

and the tunnel was sold to it's used by London Overground
