(Sarah McArthur) I remember once going to a function where

Clare Oliver was and she died from melanoma at the age of 26.

(Myles Buckley) I first became interested

in this area because I had a family friend.

He actually explained to me all the potentials

for it and I got really interested.

(Yaya Lu) The main reason I started this project

was because I wanted to enter into the Billiton.

And I thought “You know quadriplegics need independence in their movement”.

(Sarah) I examined the gene that malfunctions in

various cancers and what that gene does is it prevents

the immune system from attacking the cancer.

I was able to introduce a drug to try to reverse that effect

that the gene has on the cancers so that we're able to

overcome the cancer resistance to the immune system.

And in that way we're utilising the body's own

defence mechanisms in order to treat the cancer.

(Myles) My experiment

investigating using diatomite

which is basically kitty litter covered in a hydrophobic

coating to see whether you could absorb oil selectively off water.

You could have a new method of dealing

with oil spills; a method where the oil actually becomes

part of the solution by paying for its own removal.

You could say it's an Ockham's Razor.

It's the simplest method you could think of.

(Yaya) Well my project is largely on the idea of a voice

control system. I've developed several wheelchair

prototypes that could be used. For example, using a

wheelchair which can move sideways left and sideways right.

I've also got a wheelchair which could lift the chair

up and down to allow the quadriplegic to be able

to talk to people face to face. And I've also

developed a shopping trolley or a personal assistant.

(Michael van der Ploeg) My time at ISEF was the highlight

of my career. It was something I'll always remember.

It's a huge science fair, 1600 entries, over

three million dollars' worth of prize money.

For Intel to come on board it's wonderful and I think

it's a once in a lifetime opportunity. It was a real

celebration of science, it was a real celebration of

students work and they were treated like rock stars.

(Myles) What I'm looking forward to about ISEF is there's a

really big room full of about 3,000 projects and that means you

can just walk around and look at all these projects and they're

from all different parts of the globe. It's going to be amazing.

(Yaya) In terms of the future for this project I'm thinking

of developing a full size wheel chair. I've already had a

couple of people from Google come over and talk to me about

potentially creating a full sized wheelchair with them.

(Sara) Entering the BHP Billiton Awards and then

taking my ideas to ISEF has really given me

the confidence to keep going with this idea

and to be testing it even further and testing

myself even further. And I'm really grateful

to have been given the opportunities that

I've been given because I'd love to be able to

see this become a new treatment for cancer.
