Food for thought: Our friends in the south

Good food and south-east London are not words that you'll find written together very often. Pick up any reputable restaurant guide and you can guarantee that there'll be scant reference to eating establishments in the bottom right-hand corner of the capital.

Food for thought: tempted by the other side

The North Pole, 131 Greenwich High Road, SE10 (0181-853 3020) Locals know The North Pole as an old boozer but the owners decided not to change the name so people would know where to find it. It will also give north-of-the-river restaurant reviewers something to write about - it's probably easier to get to the real North Pole etc. However, when the DLR is finally completed, Canary Wharf will only be eight minutes away. The bar will be open all day, every day from this weekend and the restaurant will be open from Tuesday for lunch and dinner (closed Mondays). Owners Robbie O'Neill and Shaun Wilson have already identified other sites in south- east London with a view to further developments.

Television: More intimate than pillow talk

"COME WITH ME," said the mellifluous voice. And we went, although we knew it would be expensive. Because, as the voice told us, "to come with me you will have to travel across the globe from Australia, through Africa to America." Well, you know how it is. Sometimes - to find exactly what you want - it's necessary to get out and about. It's not as though you can rely on discovering it on your doorstep.

Weather: A planet fit for our children to play in

Three skydivers die in polar jump

Three parachutists died yesterday when a jump over the South Pole went tragically wrong. Investigators are trying to establish how the experienced skydivers apparently failed to deploy their chutes in time. One theory is that they may have suffered a "white out" because of the expanse of snow below them and not realised how near they were to the ground.

Weather: Where the wind blows

Aristotle was perfectly clear about wind. Since everything in the world was, in his philosophy, made of earth, air, fire and water, which in turn originate from each other, there had to be something filling the space between the earth and the nearest stars. And the only likely candidate was air. Now the air, much of which was formed by the evaporation of water, was dragged around by the rotation of the heavens. And that's what wind was.

Spill closes North Sea oil field

The oil giant Texaco said it had temporarily shut down its Captain field in the North Sea after about seven tonnes of oil were spilled into the sea. A spokesman said the shutdown was ordered early yesterday morning after an incident on the floating production, storage and offloading vessel which serves the wellhead platform.
