Hi, I'm Ayshah, this is Newsround live on CBBC, Coming up:

What do you do when you drop food on the floor?

Some fin-tastic news first up, a team of US Navy dolphins

are coming out of retirement to help scientists investigate why whales

Researchers from America think panicked whales dive away

from sonar and ship noises, causing them to drift off course

The super-clever dolphins are helping researchers

to understand why the sounds are so off putting.

Now, I love my gadgets and so does everyone at Newsround HQ,

so we went to have a look at some of the latest and best

inventions at the Wearable Technology Show in London.

And what it does is it translates sign language to text that is

displayed on the small screen, and speech that is

spoken out through this small speaker.

So as I sign, you're hearing what I'm saying

So, this is a toy and game, you use your mobile

phone or a tablet to bring them all to life using augmented reality.

This is a free to use mobile app that young surgeons who

are learning how to operate can use anywhere, any time.

And it allows them to practice on a fake patient,

So, with this, we can create interactive clothing, you can

You can draw anything you like and it lasts

for five to ten minutes before it fades away.

If you're eating your breakfast now and you drop something on the floor,

Well, now scientists say that might be OK - if you're quick!

Have you ever picked up food from the floor and eaten it?

Well, I need to get some honest answers here.

So apparently some scientists are now

saying it might not be so bad for you.

It's the so-called five second rule, but hold up, there's loads of

things you need to think about before you start telling your

brother or sister to eat stuff from the floor.

If it's sticky or sweet, probably worth giving it a miss.

If it's pasta, biscuits or dried toast, then

Have you ever eaten anything off the floor before?

If you could clearly clean it off, and

it obviously weren't dirty anymore, then probably.

If I drop something, I wouldn't eat it.

But I still don't think it's really hygienic.

What would you say to those scientist who come up with

I would go like, yes, you need to take another year on that.

Mr scientist, I don't accept your five

I don't accept your four second rule.

And I don't accept your three second rule.

And I don't accept your two second rule or one

Today is the day you get a takeover, it is the school report day. Our own

Ricky is presenting in London. Gulf good morning, we are coming live

from London. This is the radio Theatre, we've got lots of

schoolchildren because it is school report day and that means thousands

upon thousands of children will be telling us the news stories, they've

been working on their own special reports and are they as an

opportunity to get the stories on the BBC. Some will be on radio five,

breakfast and Newsround, including this man here. Junior, you are 12,

what was your story you want to tell? About my dancing and bullying.

What happened? I was bullied because my dancing and how much I loved it.

I accept, I thought it was for girls. That must have been

difficult, it is better now, but how did you get through it? I had a lot

of support, also we moved house to a better environment. Things are

better because Junior has danced with Justin Bieber on stage, that is

awesome. I had to audition, I had descend of the routine, and

depicting out of 10,000 people. That is amazing, there will be more

stories by Junior's. We have a special programme on the red button

and online, which will be myself and Tina talking about today and school
