Premier League. We have a full preview of the games of the season.

Join us then. Hello, I'm Leah and you're live with

CBBC this Monday morning. Coming up.

As the world's biggest footy tournament kicks off in just a few

weeks' time, we find out what the hot Brazilian conditions could mean

for players. And, the heart-shaped world record

that's helped a teenage boy fulfil a dream.

This is Newsround. First to Tokyo in Japan, where a

strong earthquake has hit the city overnight. These pictures show the

moment the quake struck in the early hours of Monday morning, shaking

buildings across the Japanese capital, though there are no reports

of major damage or any serious injuries. Researchers say it was the

strongest tremor felt in the city since a series of major earthquakes

hit the region in 2011. Next, could your six-week summer

holiday be scrapped? Well, head teachers at schools across England

are considering spreading the summer break more evenly through the year.

The proposal is part of a new education policy being discussed by

the National Association Of Head Teachers. The group's leader Russell

Hobby has said that a shorter summer break could stop teachers getting

too tired and cut expensive summer-holiday prices for families.

Well, we want to hear what you think about this. Would you rather have

more, shorter holidays through the year, or one long summer holiday,

and why? Tell us on the website. The British tennis number one Laura

Robson has paid tribute to her friend and team-mate Elena Baltacha,

who has died overnight at the age of 30 from liver cancer. Baltacha was

herself the British number one for three years, and played for Team GB

at the London Olympics in 2012, as well as thrilling the Wimbledon

crowds. Born in Ukraine, she moved with her family to the UK and grew

up in Scotland. She had a career troubled by illness and retired

earlier this year. And if anything in the news upsets

you, don't forget our website has help and advice for you.

Next month, some of the best football players in the world will

be heading to Brazil for the World Cup. While there's lots of

excitement building around the competition, there's also worries

the hot Brazilian climate could affect players.

The World Cup is the biggest sporting event on the planet, and

this summer it is Brazil's turn to host, as countries battle it out to

be the best. Matches are being played at 12 stadiums across the

country, from Rio to junior row to Manaus. Brazil has a hotter climate

than us, and in the north and west of the country, it is especially hot

and humid. Temperatures are regularly above 30 degrees. With

some matches due to kick off at 1pm Brazil time, the hottest part of the

day, some people are concerned it will be too hot. Football matches

are not normally played at that time in those areas, so why are matches

being played so early? The most important TV audience is in Europe,

so FIFA want three separate kick-off times per day, all of them

convenient for the European audience. With the time difference

between Brazil and the UK, the only way to do that is to start early.

You would never have a big local game kicking off at 1pm in the

north-east of Brazil, it is too hot. The players and coaches tell me it

is inhumane to expect World Cup players to run around in that heat.

There will be breaks for the players to drink water, but they will get

tired more quickly, and it will not be easy for them to recover in time

for the next match. FIFA have ruled out changing the start times, so

teams will have to suffer the pressure of heat.

Now, you might have heard of teenager Stephen Sutton. He's become

well known for raising more than ?3 million for charity over the last

four years. Well, now the 19-year-old from Staffordshire, who

has a form of cancer, may have got himself into the record books for

getting 554 people together to make heart-shaped hand gestures at the

same time for three minutes. Event organisers say the previous record

was 501. Stephen has a bucket list of things he wants to do before he

dies, and he thanked everyone for turning up.

Hello, everyone! I will keep it short and sweet, but thank you for

coming, it is good to be here. Thank you.

Music now, and Calvin Harris has scored his sixth UK number one. The

DJ and producer knocked Mr Probz and his single Waves off the top spot in

Sunday's official chart with his new track Summer. Last year, Harris

became the first artist in UK music history to have nine top-ten singles

from one album. His new album is due out later this year.

Newsround's back right here in about half an hour, when we'll hear from

British tennis number one Andy Murray about who he might choose as

his next coach.
