Evening all! Newsround taking over BBC One. Leah and Ricky with your

:00:27.:00:31.

headlines. We've got plenty on the way for you this Thursday,

:00:31.:00:34.

including all of this... We'll tell you once and for all whether food

:00:34.:00:38.

off the floor is ever all right to eat. And the robotic arm you

:00:38.:00:42.

control with your mind. Before all that - how comfortable are you in

:00:42.:00:46.

the water? New figures out today claim thousands of kids aren't

:00:46.:00:49.

learning to swim and could be putting themselves at risk as a

:00:49.:00:53.

result. Leah, you've been looking into this one today. Well Ricky,

:00:53.:00:56.

swimming in schools is on the national curriculum which means it

:00:56.:00:59.

should be compulsory for you to learn. You're supposed to be able

:00:59.:01:03.

to swim at least 25 metres by the time you leave primary. But this

:01:03.:01:06.

new research from the Amateur Swimming Association claims that

:01:06.:01:08.

more than 200,000 children are leaving Primary School unable to

:01:08.:01:13.

swim at all. What's more, they've found that four out of 10 of those

:01:13.:01:17.

kids aren't being given the chance to even learn. So we've been asking

:01:17.:01:20.

you how important you think it is to learn to swim. We caught up with

:01:20.:01:30.
:01:30.:01:32.

these kids at a pool in Stockport. If you fall in somewhere and catch

:01:32.:01:36.

something you could die. More a dog could not swim and fell in the

:01:36.:01:39.

water so I went in and tried to pull him out. Because of swimming

:01:40.:01:44.

lessons you could do that? Yes. would prefer to have more schools

:01:44.:01:49.

having swimming lessons, it means more people can learn how to swim.

:01:49.:01:59.
:01:59.:02:03.

You've been getting in touch on the Georgina from Essex doesn't like

:02:03.:02:06.

going swimming with school - she thinks children should only go if

:02:06.:02:12.

they want to or can't swim. With me on the sofa is Matthew McFahn from

:02:12.:02:16.

the Amateur Swimming Association, the people who did this study.

:02:16.:02:21.

Isn't swimming like any other sport, if kids can't do it, why should

:02:21.:02:26.

they try? In his hugely important, a life skill, the only sport that

:02:26.:02:30.

can save your life. That is vital and will allow youngsters to enjoy

:02:30.:02:35.

the water in a pool, on holiday, with their parents, going to

:02:35.:02:39.

friends with a pool, or even by a river and need to be safe. We have

:02:39.:02:42.

been in touch of the government and they said toss it is compulsory.

:02:42.:02:49.

What else can be done? The key thing is for the government to try

:02:49.:02:53.

to make sure inspectors spend more time looking at swimming and making

:02:53.:02:57.

sure schools do something. They spend a lot of time on maths and

:02:57.:03:01.

English and making sure academic subject a done but this is a life

:03:01.:03:07.

skill that could save a life. can be expensive for some schools.

:03:07.:03:12.

It can. Travel costs could be an issue but I know local councils are

:03:12.:03:16.

working with schools trying to make a difference. If we can get that

:03:16.:03:23.

right every child could have a chance of swirling. -- swimming.

:03:23.:03:26.

Matthew, thanks for coming in. Moving on now and being able to

:03:26.:03:29.

control something just with the power of your mind sounds pretty

:03:29.:03:33.

amazing. Yep, you could get your mum to do your homework for you. Or

:03:33.:03:36.

you could make your brother make your bed. But scientists in America

:03:36.:03:39.

have been developing a much more serious use for it. Nel's got all

:03:39.:03:41.

the details. Cathy Hutchinson is paralysed from

:03:41.:03:44.

the neck down. She hasn't been able to serve herself a drink for almost

:03:44.:03:49.

15 years. But that all changed in this moment. It's down to the box

:03:49.:03:55.

screwed onto her head. It has a sensor linked to her brain and

:03:55.:04:00.

that's controlling the robotic arm. She can't speak but the look on her

:04:00.:04:05.

face tells you she's ecstatic. So how does it work? A tiny sensor

:04:05.:04:09.

smaller than a five pence piece is implanted onto the top of the brain.

:04:09.:04:12.

It picks up electrical activity from the brain and turns it into

:04:12.:04:17.

commands for the robotic arm. was a moment of true joy, true

:04:17.:04:22.

happiness, it was beyond the fact that it was an accomplishment. An

:04:22.:04:29.

important advance in the entire field of brain computer interfaces.

:04:30.:04:32.

This is not the first time scientists have experimented with

:04:32.:04:35.

mind control. In January this injured British soldier was fitted

:04:35.:04:40.

with a bionic arm which he can move with his brain. Here's a researcher

:04:40.:04:44.

using his thoughts to tell his wheelchair where to go. And this is

:04:44.:04:46.

Ricky trying out a computer game where you can control your

:04:46.:04:56.

character via your headset! It's pretty fast. It's still early

:04:56.:04:59.

stages but this latest development is a big step towards the long-term

:04:59.:05:03.

goal of being able to use brain sensors to help the people who need

:05:03.:05:11.

it most. The Russian spacecraft successfully docked today, the

:05:11.:05:15.

astronauts will spend four-and-a- half months looking at the wonders

:05:15.:05:21.

of the universe. So lucky. Back on earth, whether it's watching a new

:05:21.:05:23.

family of lion cubs or tracking American black bears Planet Earth

:05:23.:05:27.

Live is one of the most ambitious wild life series ever! It's been

:05:27.:05:29.

following some of the world's most amazing creatures live. And this

:05:29.:05:32.

morning we spoke to one of the presenters Richard Hammond all the

:05:32.:05:37.

way from Kenya. That is the 10th I broadcast from. We are running

:05:37.:05:40.

about getting ready for the show this evening but I wanted to show

:05:41.:05:46.

you something you don't normally see. This is one of the camera cars

:05:46.:05:52.

they used to go out and fill the animals. All this frame built on

:05:52.:05:55.

the side, this is the spot and drivers are she knows where

:05:55.:05:59.

everything is out there, it is her job to drive this car over

:05:59.:06:06.

unbelievable territory so we can get the shots. They are up and away

:06:06.:06:14.

at about 5:30am. I will up day you on how the animals are doing. Right

:06:14.:06:18.

now it is not raining in the rainy season, which is lovely. I hope you

:06:18.:06:25.

will be there with us tonight, 8pm BBC One. I will be watching. OK

:06:25.:06:29.

Leah. You've dropped a crisp on the floor. What do you do? Three second

:06:29.:06:34.

rule. Well, believe it or not, scientists are actually looking

:06:34.:06:38.

into the theory behind the three second rule to find out if it's

:06:38.:06:42.

right. There is nothing a lot more than sitting back with a cup of tea

:06:42.:06:51.

We've all been there. You drop something on the floor, pick it up,

:06:51.:06:58.

dusted off and carry on. It's called the three-second rule. But

:06:58.:07:00.

scientists have started fighting back against this time old

:07:00.:07:05.

tradition, they are putting food through its paces to see if it

:07:05.:07:12.

passes the test. How does it work? We dropped different types of food

:07:12.:07:17.

onto the floor, left them for three, five or 10 seconds, then put it

:07:17.:07:22.

into a machine which mimics the stomach. It mashes it up into

:07:22.:07:27.

liquid, then the liquid is transferred on to some plates which

:07:27.:07:32.

will throw up different types of bacteria. Scientists worked out

:07:32.:07:37.

that wet foods like jam and ham will still pick up bacteria if you

:07:37.:07:40.

drop them on the floor. Because these foods have high levels of

:07:40.:07:46.

sugar and salt the bacteria is less likely to grow. Have you worked out

:07:46.:07:49.

that the three second rule is not necessarily always right? There was

:07:49.:07:52.

not any significant difference between leading the food on the

:07:52.:07:57.

floor for three, five or 10 seconds. If there was bacteria there it

:07:57.:08:03.

would be there at three seconds. there we have the science behind it.

:08:03.:08:07.

What have we learnt? Experts say it is never a good idea to eat food

:08:07.:08:12.

that has fallen on the floor, instead, why not try and stick to

:08:12.:08:22.
:08:22.:08:22.

Now just about now Britain will finally get its hands on the

:08:22.:08:26.

Olympic torch. It's being officially handed over to the UK at

:08:26.:08:29.

a special ceremony in Greece. David Beckham and Princess Anne will then

:08:29.:08:32.

bring it back home before the torch relay starts here on Saturday.

:08:32.:08:35.

sticking with the Olympics - one of Hollywood's biggest names has been

:08:35.:08:41.

getting special 2012 training session. Men in Black star Will
