[00:00.01]A British scientific expedition to a remote rainforest in Papua New Guinea has discovered a new species of giant rat, one of the biggest in the world.
[00:10.53]The Bosavi woolly rat is the size of a small domestic cat, weighing around a kilo and a half.
[00:16.05]It was found by a BBC wildlife film crew.
[00:19.35]Here's cameraman Gordon Buchanan.
[00:21.57]This is the biggest true rat in the world.
[00:24.98]Unbelievable! It's actually so big.
[00:28.07]It doesn't look like a rat.
[00:29.49]This fellow is just incredible.
[00:32.10]This is a really significant finding for expedition.
[00:36.54]The people of the South Pacific nation of Samoa are switching to driving on the left-hand side of the road today, the first country to change sides since the 1970s.
[00:46.37]The move survived a legal challenge from a protest group which argues that it would lead to chaos.
[00:52.19]The emergency services have been conducting demonstrations to show drivers what to do.
[00:56.98]And a two-day national holiday has been declared to minimise disruption.
[01:01.10]The Samoa government says the change would allow people to drive cheaper imported cars from Australia and New Zealand, which also drive on the left.
