How Spike the stag beetle is changing the art world.

And the cows trumping climate change.

Massive news for Whovians - a new Doctor has been revealed.

Jodie Whittaker will be the 13th Time Lord.

She's the first woman to play the character in the show's history,

and will start when the Doctor regenerates in the

We've been asking what you think about it.

I was really happy because I have heard that it has just been male

since it started. It is going to go very good, because I know females

can do the same thing as males. I don't think the woman will be better

than the man because men are better at acting. I'd like to see her

change the spaceship sort looks more up-to-date and she could change the

colour. But now there's a huge row

about the way they've been marked. Two tests with the same question

and the same answer, but one has been marked right

and the other is wrong. That was a real question in a recent

Sats test for 10 to 11-year-olds, but it's the way these questions

have been marked that's got a lot So we've got some examples right

here, and we want these guys to see if they can tell what's right

and what's wrong. I think it's right because

they did put the letters Well, I think the commas

are inserted in the right place So should that matter,

the way it goes? No, because the student knows how

to do it, but they're just being told off for not

doing it right. Although children answered the right

question, some failed to get a mark because of the shape

of their semicolon and commas. Others got marked down for not

putting their answer inside a box, even though it didn't tell

you you would get marked down I think it's unfair

because the person who has written the comma like that could have got

99, which is one mark I think this is the wrong

way to test people. They should have told them then

they could have known If you can see a semicolon,

then you can see a semicolon. It tells you to put it

in the right place, which is what these people have

done, but they've still lost the mark even though they've done

the question as it said. Some teachers have spoken

out on social media, saying they weren't told

about the marking rules. So we got in touch with the people

who come up with the test, as well as the Department for

Education. They're the people in Government

in charge of schools. The Government told Newsround

that they wanted to make sure children were using and forming

punctuation correctly and had given advice to people marking it

to make sure it was fair. And Pearson, the company in charge

of marking your tests, told us that mistakes in marking

are rare but they want teachers who are worried to get in touch

so they can look into it. The Humber Bridge and a block

of public toilets in Hull have both They have been honoured

with a listed status, alongside seven other places

in the city, to celebrate Hull during its year

as the UK City of Culture. But what exactly does

getting listed status mean? Head to Newsround

online for our guide. This beetle is on his way to

becoming a famous artist. Spike shot to fame last week

after his human teacher posted Now one of his paintings has sold

for more than ?1,200. Finally to the cows

helping to save the world. Allow to explain: When cows

release wind they produce something called Methane Gas,

which is harmful to the environment. Now farmers in Kenya think

they have come up with a plan They say a good balanced diet
