New Dr Who named

One of the most popular UK TV shows worldwide is Dr Who. This science-fiction show is about a time-travelling alien, whose spaceship is an old-fashioned police telephone box (called the Tardis). The Doctor usually travels with human companions, spends a lot of time saving Earth, and fights bad aliens called Daleks and Cybermen.

The show has been running since 1964, so the actor playing the Doctor has changed several times. The show explains this as the Doctor "regenerating". Until now the Doctor has always been male and white.

When the current Doctor, Peter Capaldi, announced he would leave the job, there was lots of comment about whether the next Doctor might be a woman, or black – or both.

The new Doctor was finally announced after the Wimbledon men's tennis final ended and… it is a woman, Jodie Whittaker, who has starred in films including Attack The Block and a TV crime series called Broadchurch.

There have been lots of arguments on Twitter about the Doctor being a woman. Some people are horrified. One man said: "The Tardis will be full of bras."

A very strange story about the Queen

Swans are large white birds which swim on our rivers and ponds in the UK. They also all belong to the Queen – well, most of them do.

900 years ago, the Royal Family claimed ownership of mute swans in England, because the birds were good to eat at feasts. Several hundred years later, two groups of trades people were given the right to own swans on the Thames in London, with the Queen.

Now, every year, the group dresses up in special costumes to count and label the swans. This happened last week, and is called Swan Upping.

Whale beats dinosaur at London museum

The Natural History Museum is one of our most popular visitor attractions. It has an amazing building, a very popular dinosaur gallery, and a huge collection of animal, plant and rock specimens.

Its most famous exhibit has been Dippy, the 21-metre dinosaur skeleton which has stood in the huge entrance hall since 1979. But Dippy was not a real skeleton. He has now gone – and in his place is an even bigger skeleton, of a blue whale which died on an Irish beach in 1891.

The 25-metre skeleton has been hung high in the museum's mammals gallery since the 1930s.

The museum decided to move the blue whale to the entrance hall to show that it was not just about old bones, but looking after the planet. Blue Whales are the largest animal known to have existed on Earth, and were very common when the museum's specimen was alive.

But they were hunted until 1966, when they were almost extinct, and since then numbers have risen to about 20,000.

One senior member of the museum's staff was inspired by seeing the whale skeleton when he was 10. "Our objective is to inspire other 10-year-old boys and girls, get them into marine science, get them working for the future," he said.

Dippy the dinosaur has not disappeared. The museum is getting a strong frame built for the skeleton so that it can go on tour round the UK from next year.

Who won Wimbledon?

The women's singles was won by Spanish player Garbine Muguruza, for the first time. She beat Venus Williams, who has won the trophy five times. Two years ago Muguruza was beaten in the final by Venus's sister Serena. "She told me one day I was going to win, two years after, here I am," she said.

The men's final was won by Roger Federer for the eighth time. He is the first man to win eight times, and also the first man to win the tournament without losing a set since 1976. "Wimbledon was always my favourite tournament, and will always be my favourite tournament," said Federer. His wife and four children – two sets of twins – watched him play.

Federer beat Croatian player Marin Cilic, who had an injured foot.

One man will be pleased Federer won – he placed a GBP 50,000 bet on him and didn't tell his girlfriend what he had done.
