South Africa's President, Jacob Zuma, has denied acting

:00:07.:00:08.

dishonestly in a scandal over public funds spent on renovations

:00:09.:00:11.

But he has promised to obey an order to repay some of the money.

:00:12.:00:19.

The US military says it has carried out a drone strike in Somalia

:00:20.:00:22.

targeting a vehicle carrying three members

:00:23.:00:24.

A Pentagon spokesman named the principle target as

:00:25.:00:27.

Hassan Ali Dhoore, who was accused of organising recent bomb attacks

:00:28.:00:30.

on Mogadishu airport, and a hotel in which US personnel were killed.

:00:31.:00:42.

Now on BBC News, it is time for Click.

:00:43.:00:47.

The -- this week, changing the world with a pencil. Bringing performance

:00:48.:00:57.

to life. And scaring people to death.

:00:58.:01:24.

As amazing as our devices are today, as fast as they run, and as small as

:01:25.:01:35.

they get, Beryl limited by physics. Their limited by the substances that

:01:36.:01:40.

they're made from -- they are limited. We dream of devices that

:01:41.:01:43.

are flexible, wearable, see-through, and, well, just plain future-y. It

:01:44.:01:56.

is a real word, trust me. But before we can do that, we need a substance

:01:57.:02:01.

that can do all those things, be all of those things. Fortunately, such a

:02:02.:02:05.

substance exist. Heroes for decades but only finally created in a lab in

:02:06.:02:13.

2010, by these guys, it was such an amazing feat that it won them the

:02:14.:02:20.

Nobel Prize in Physics. Right, here is how you win a Nobel Prize. Take

:02:21.:02:24.

one pencil and some sticky tape, and you see that? Now, on their,

:02:25.:02:38.

somewhere, a -- flecks of graphite from a pencil, these are known as

:02:39.:02:43.

graphene and they will change the world. Graphene is a single atomic

:02:44.:02:50.

layer of carbon, they are just one atomic layer and yet they have all

:02:51.:02:53.

kinds of fascinating physical properties. So you have a flawless

:02:54.:02:59.

piece of graphene, electrons can move politically without being

:03:00.:03:02.

scattered around. And electrons move as if they have no matters. So it is

:03:03.:03:08.

relativistic. So better than silicon? Oh yes, much better than

:03:09.:03:13.

silicon. The mobility can be hundreds or thousands of times

:03:14.:03:18.

higher than Telecom. Faster? Yes, very good conductivity, and also

:03:19.:03:22.

because it is one atomic layer is transparent. So if you can imagine

:03:23.:03:26.

you have a sheet with transparent electorates. Transparent electronics

:03:27.:03:32.

make all sorts of things possible. Suddenly anything can become a

:03:33.:03:36.

display without locking your view of what is behind. Solar cells can

:03:37.:03:39.

become a lot more efficient if you put the electron collecting

:03:40.:03:44.

circuitry right on top, without locking the sunlight. And graphene

:03:45.:03:48.

is not only transparent and flexible, it is also incredibly

:03:49.:03:53.

strong. As for atom, 207 times stronger than steel. Meet

:03:54.:04:01.

professional cyclist Mr Barker. Today his bike is sporting a new set

:04:02.:04:07.

of super strong wheels, graphene ones. That means he can tackle

:04:08.:04:10.

terrain he would normally steer well clear of like Roque in glass or, in

:04:11.:04:16.

explicit week, a nail board. -- inexplicably. These tyres made by

:04:17.:04:23.

bike giants Victoria are made from special rubber which include flex of

:04:24.:04:26.

graphene to improve their strength dramatically and without the extra

:04:27.:04:30.

weight normally carried by other puncture resistant tyres. You had to

:04:31.:04:35.

imagine that the tyres are always full of conflicting targets. You

:04:36.:04:38.

want the grip but you want the milage as well. You want low road

:04:39.:04:43.

resistant and wait but you also want higher puncture resistance. Because

:04:44.:04:47.

graphene is able to make a tyre lighter, less rolling resistance, at

:04:48.:04:52.

the same time more milage and more grip. That was impossible with the

:04:53.:04:58.

existing compounds so far. The rims are made from carbon fibre that is

:04:59.:05:02.

also infused with graphene, which turns out as well at being very good

:05:03.:05:10.

at dissipating heat caused by the breaks. And it is this ability to

:05:11.:05:14.

bind graphene to other substances, improving those materials in the

:05:15.:05:19.

process, that has sparked a lot of interest from scientists around the

:05:20.:05:25.

world. And you can do all sorts of things with graphene. What you do

:05:26.:05:28.

with it depends on what material you deposit on top of the graphene.

:05:29.:05:32.

While graphene is only one atom thick, the materials you put on top

:05:33.:05:38.

are also only a few atoms thick. To do that you need instruments like

:05:39.:05:44.

this. At the UK's graphene Institute in Manchester, researchers are

:05:45.:05:48.

exploring all sorts of applications for this wonderful material. It is

:05:49.:05:51.

being used as a waterproof coating to make our houses damp resistant.

:05:52.:05:58.

It can even be used to purify water. This graphene mesh is already

:05:59.:06:02.

capable of sieving out many impurities but the ultimate goal is

:06:03.:06:07.

to come up with a graph graphene membrane that can turn the water

:06:08.:06:11.

into drink and water in about the same amount of time it takes to

:06:12.:06:14.

filter coffee. Right, so graphene is amazing. At everything. We get it.

:06:15.:06:22.

So why isn't it already in everything? Why is it so far only

:06:23.:06:28.

really being mixed in small flecks with other substances? Well, because

:06:29.:06:32.

we can't yet make it in both big enough sizes and higher enough

:06:33.:06:38.

quality at the same time. You can grow larger samples of graphene on

:06:39.:06:43.

copper sheet, but because of the really high temperatures involved,

:06:44.:06:48.

the graphene is deformed and not very good quality. If only there was

:06:49.:06:51.

a way of growing large graphene sheets on copper but at much lower

:06:52.:06:57.

temperatures. Well, turns out there is. Across the pond, at the

:06:58.:07:05.

California Institute of Technology, they've got a leaky gas valve. We

:07:06.:07:09.

found out, by accident, that we had some leaky valves. I thought I had a

:07:10.:07:14.

hydrogen is, what it was leaking just a small amount of methane. This

:07:15.:07:20.

isn't a very good vacuum system. So you had shoddy equipment. Yes. That

:07:21.:07:26.

led to a world changing discovery. Absolutely. Kids, there is a moral

:07:27.:07:33.

in that. Do not maintain your grip and, just let it go to pot. Hydrogen

:07:34.:07:37.

plasma is only supposed to clean the copper while making graphene at

:07:38.:07:44.

temperatures of 1000?C. Let's try to have plasma assisted growth, and so

:07:45.:07:49.

we lowered the growth temperature from 1000 to 800, and then my group

:07:50.:07:55.

members found that graphene still grows. And then we say, OK, let's

:07:56.:08:00.

lower the temperature further, the environment and temperature to 600.

:08:01.:08:05.

Still grows. And then took 400, still grows. And then, can we turn

:08:06.:08:09.

off the heat and just grow the sample with plasma assistance at

:08:10.:08:13.

room temperatures? And we discover that this graphene has very few

:08:14.:08:18.

defects in it, which means it has very good electrical properties.

:08:19.:08:22.

Graphene is inching ever closer to a fulfilling its promise as this

:08:23.:08:27.

all-purpose wonder material. And in fact, even now, scientists are

:08:28.:08:31.

working on other substances, themselves just one atom thick,

:08:32.:08:35.

which also promised to have superpowers. The world, it seems to

:08:36.:08:45.

me, is getting very 2-dimensional. Another week, and another operating

:08:46.:08:54.

system update from Apple, which brings one or more features of its

:08:55.:08:58.

phones. This time it is the Safari web browser. If iPhone owners try to

:08:59.:09:02.

click on web links these links can freeze or even crash the app. After

:09:03.:09:07.

several days of problems, Apple says it has fixed the issues. Whatever

:09:08.:09:11.

happened to it just works, he? Microsoft tried to make waves this

:09:12.:09:15.

week with its annual Build conference. The company unveiled a

:09:16.:09:21.

series of chat bots meant to help us go about our daily lives. Let's hope

:09:22.:09:28.

they work better than Microsoft's team chat bots, Tay, which had to be

:09:29.:09:32.

switched off after tweeting offensive comments. Microsoft also

:09:33.:09:35.

gave journalists the chance to experience its much hyped augmented

:09:36.:09:44.

reality headset, Hololens. Bad news for Facebook after it was forced to

:09:45.:09:49.

apologise. It's a safety check system wrongly asked people if they

:09:50.:09:51.

were caught up in the Pakistan bomb attack which killed over 70 people

:09:52.:09:56.

last weekend. The FBI announced they have succeeded in accessing the

:09:57.:10:02.

smartphone of San Bernardino gunman Syed Farook without the help of

:10:03.:10:10.

Apple. And DARPA have been testing their continuous trial unmanned

:10:11.:10:13.

vessel. It has been designed and built to travel thousands of miles

:10:14.:10:17.

without a single crew member on board. Open water testing will begin

:10:18.:10:19.

off the California coast this summer. With Apple and Samsung

:10:20.:10:29.

absolutely dominating the smartphone market these days, it seems like all

:10:30.:10:35.

the other manufacturers have to do something really special in order to

:10:36.:10:39.

get any interest at all. Well, that is what LG is hoping it has done

:10:40.:10:46.

with its new phone G5. We caught a glimpse of it in Barcelona in

:10:47.:10:52.

February, and LJ Rich has her hands on the first full production model

:10:53.:10:56.

to land in the UK a head of the launch. We have seen modular phones

:10:57.:11:00.

on the market for a little while, at a big manufacturer like LG wants to

:11:01.:11:04.

do something a little bit different, and they have always prided

:11:05.:11:06.

themselves on being able to swap batteries. So the idea is, instead

:11:07.:11:11.

of just swapping batteries, why don't you swap more? For example,

:11:12.:11:15.

you can put a high-end audio converter on the end, or a little

:11:16.:11:19.

grip that allows you to take pictures 1-handed. And it gives you

:11:20.:11:25.

a wheel to zoom with, and an extra battery burst at the same time. Now,

:11:26.:11:31.

swapping modules also boosts the phone because you take the battery

:11:32.:11:36.

out. It automatically recognises the new added end. LG have designed a

:11:37.:11:39.

phone it actually wants you to pull apart, in stark contrast to the

:11:40.:11:44.

closed culture of other smartphones. It is also getting other brands

:11:45.:11:48.

involved with a plug and play digital to analogue converter or

:11:49.:11:56.

DAC. Higher end DAC can produce a more detailed and clearer sound. So

:11:57.:12:00.

when listening to jazz you can also hear the space created by the drums

:12:01.:12:06.

and in this case saxophone. I'm actually very impressed. It is worth

:12:07.:12:09.

mentioning that the DAC sound module can work on its own, which I think

:12:10.:12:16.

is a very savvy approach. Sean from LG is sharing something from his

:12:17.:12:19.

playlist and I asked him how future proof these modules can be. It looks

:12:20.:12:27.

like this will only work with that unibody, and then when you get the

:12:28.:12:31.

next phone up does that make this obsolete? That's a good question. I

:12:32.:12:34.

think at this particular moment in time the modules have been developed

:12:35.:12:39.

for the G five. The module idea is not going to be unique just to the

:12:40.:12:47.

G5. We are trying to make as many of the modules as flexible as possible.

:12:48.:12:51.

But for the time being, yes, they are fit for purpose on the G5. As we

:12:52.:13:06.

consume more content on the go, our choice of headphones has become

:13:07.:13:11.

increasingly important. So I have been testing some of the latest,

:13:12.:13:23.

more interesting options. These are the Ear-In earbuds, a pair of

:13:24.:13:27.

totally wireless headphones. While they are in this container not only

:13:28.:13:31.

are they being kept clean but they are also being charged. As long as

:13:32.:13:34.

you judge the case it can power them up three times. Once you have

:13:35.:13:37.

introduced them to your phone via Bluetooth, the left one will

:13:38.:13:40.

automatically sync up once it has been taken out of the case, and then

:13:41.:13:44.

the right earbud will connect to the left earbud and from there you can

:13:45.:13:48.

play your tunes. I have no complaints about the sound quality

:13:49.:13:53.

or the connection, but I do feel slightly conscious that they could

:13:54.:13:57.

fall out of my ears, which makes me feel comfortable walking, but a

:13:58.:14:02.

little less sure about running. Taking the idea of wireless

:14:03.:14:08.

headphones to another level are these, a pair of smart headphones

:14:09.:14:12.

that are definitely designed for life on the go. They can track

:14:13.:14:16.

activities including swimming, if you trust them to stay in your ears,

:14:17.:14:20.

and track heart rate as well as stream music from your phone, or

:14:21.:14:24.

play tracks stored on them. While the touches and swipes to operate

:14:25.:14:31.

our intuitive to use, at some point I found that even on top volume the

:14:32.:14:36.

music didn't seem to be loud enough. But the time I really felt the

:14:37.:14:40.

benefit of these headphones was when I was walking and making phone calls

:14:41.:14:43.

on the go, because the person on the other end, even though the

:14:44.:14:46.

microphone was in here, couldn't tell that I was holding my phone

:14:47.:14:54.

handset. -- wasn't holding. They do offer the option of sound

:14:55.:14:57.

transparency being on or off so you can hear your surroundings if you

:14:58.:15:02.

choose. And for those it is a priority for, so cyclists or people

:15:03.:15:05.

who run on busy streets, the latest in phone conduction technology could

:15:06.:15:10.

come in handy. The sound travels through vibrations on your

:15:11.:15:13.

cheekbones rather than playing directly into your eardrums. I was

:15:14.:15:18.

actually really impressed by the sound quality, and I've never felt

:15:19.:15:23.

so save pounding the streets of London. But after a little while I

:15:24.:15:27.

did start to feel that the vibrations on my cheeks were feeling

:15:28.:15:31.

a bit odd. I think that maybe because they had made the volume is

:15:32.:15:36.

so high. For something that looks a bit different, this is LG's latest

:15:37.:15:40.

offering. You pull it out like this. It is ridiculous. Why is that

:15:41.:15:46.

necessary? OK, actually, that isn't bad. If you move your head a lot you

:15:47.:15:48.

makes you want them to be longer. The turn Platinum can receive high

:15:49.:16:01.

res audio, has dual noise cancelling iPhones building and some added

:16:02.:16:04.

voice control benefits for android phone users. But the design seems to

:16:05.:16:10.

be a matter of taste. These are more about sound quality than something

:16:11.:16:14.

you should run with, especially how they feel on my neck, so for that

:16:15.:16:18.

reason I'm going to take a seat... For no other reason at all. So

:16:19.:16:22.

however active or not you're expecting to be, there are options

:16:23.:16:27.

aplenty offering something beyond the basic factors of looks, fit and

:16:28.:16:37.

sound quality. Now, in some kinds of theatre the

:16:38.:16:42.

lighting can often be as important as the sets, as the choreography, as

:16:43.:16:50.

the performances themselves. With the latest motion sensing

:16:51.:16:53.

technology, the brain that programmes that lighting might not

:16:54.:16:59.

be human. One British choreographer and one computer programmer have

:17:00.:17:04.

between them created an artificially intelligent performance where the

:17:05.:17:08.

lighting responds to two dancers on stage. Jane Caro take has been to

:17:09.:17:20.

see it in action. The Xbox connects we are using in this space which

:17:21.:17:26.

cracks our bodies uses artificial intelligence. When we stand in front

:17:27.:17:29.

of them they immediately recognise the shape of the body, they picked

:17:30.:17:37.

out a skeleton structure. Alex, where are we right now? We are at

:17:38.:17:44.

Cambridge Junction and we're doing our rehearsals for the second

:17:45.:17:46.

preview of the new performance of hours. The four on the left... Four

:17:47.:17:55.

on the left. The ones on the left are following you and the ones on

:17:56.:17:58.

the right are following me. If I go down here they should finally. The

:17:59.:18:08.

Cure neckeds are able to follow us and predict where we're going to go

:18:09.:18:10.

next, there's a system that can learn from the movement it observes

:18:11.:18:16.

and make more informed choices about the way, the lights on the stage

:18:17.:18:24.

work with us. It's about observation systems predicting the next steps.

:18:25.:18:30.

So I see this stage as an instrument. So what Alex as a

:18:31.:18:36.

choreographer creates in my mind could not be created in any other

:18:37.:18:41.

way. You might watch the finished show or a lighting designer,

:18:42.:18:45.

traditional lighting designer, might watch the finished show and they

:18:46.:18:48.

might think they could programme that, it might take them really long

:18:49.:18:52.

because there's a lot of intricate behaviour. But even if they could

:18:53.:18:57.

it's not the same because the reason why the choreography is the way it

:18:58.:19:02.

is because Alex choreographed it in this setting.

:19:03.:19:09.

We've got a system where we can control how they move with the

:19:10.:19:16.

position of our hands. See that's backwards. That's it, so you're

:19:17.:19:21.

bringing them round. When they're together they won't move. It should

:19:22.:19:29.

stop... Yet, that's it. The lights on stage almost look like dancers,

:19:30.:19:35.

do you see them that way? It's very tempting to see them that way. There

:19:36.:19:39.

are certain modes when they do look so alive and to me that's a

:19:40.:19:40.

success. That was Jen really getting into her

:19:41.:19:50.

part there, although you'd never catch me wearing a leotard

:19:51.:19:58.

on-screen. Anyway, there are some performances which actually require

:19:59.:20:00.

audience participation, something you will know if you have ever taken

:20:01.:20:06.

part in immersive theatre. Hear the audience actually becomes part of

:20:07.:20:10.

the show as the action happens all around you. Well, a terrifying new

:20:11.:20:17.

experience has come to east London, which promises to immerse audiences

:20:18.:20:24.

even deeper in virtual reality. Without briefing him about his

:20:25.:20:28.

impending doom or anything at all for that matter, we sent Click's

:20:29.:20:33.

resident scary cat to suffer an evening with the virtually dead. And

:20:34.:20:38.

a quick spoiler alert, if you've bought tickets for this show, if

:20:39.:20:43.

you're watching with young children or can't stand the sight of a grown

:20:44.:20:47.

man screaming like a little boy, look away now.

:20:48.:20:51.

We are in Hackney Wick, I have no idea what's going on, there's an

:20:52.:20:56.

army man shouting at me over there. Down and give me ten. Come on,

:20:57.:21:10.

Rambo! Come on, chop, chop, chop. We are going to location unknown. I

:21:11.:21:14.

feel like I'm in a 90s rock music video. Everybody out, let's go. Come

:21:15.:21:17.

on. Let's go, let's go. Immersive theatre is obviously a massive thing

:21:18.:21:25.

at the moment but VR has never been put in it, we want to do something

:21:26.:21:30.

that's never been done before. Our home state of Arizona is overrun by

:21:31.:21:38.

a terrible infection. The goal was to blur the lines between what's

:21:39.:21:42.

real and what's not. As soon as you enter an immersive theatre you're

:21:43.:21:45.

stepping out of normal reality and in our eyes it was, OK, can we take

:21:46.:21:51.

that one step further? Oh my God. Holi... Go, go, go! We created a

:21:52.:22:07.

story here where we are training the soldiers to go to Arizona to kill

:22:08.:22:10.

zombies, and the VR we think has been sandwiched perfectly in the

:22:11.:22:16.

middle of the theatre, so it's the middle of the training process. What

:22:17.:22:22.

about these recruits? Do we cancel their training? No. Right, you lead

:22:23.:22:34.

through the door. Welcome to VR training. There are over 70 sensors

:22:35.:22:41.

in these things here my neck, it's the only VR system that allows you

:22:42.:22:45.

to move within your environment. With immersive theatre it's all

:22:46.:22:49.

about making things one-on-one, the beauty with VR is you can have this

:22:50.:22:54.

immersive solo experience with a headset on. Can you see these things

:22:55.:22:59.

here? Hands up, Nick. These things will be picked up and used to

:23:00.:23:02.

shoot. We are looking for a simulation. Now, Nick, remember, you

:23:03.:23:09.

been a small contamination issue. I need to leave this room. Don't die,

which is a good thing. Honestly, like,... How did you feel it when?

It was great. When I was immersed in the headset, it was, like,

It is set to be a chilly start to the weekend.

:25:12.:25:16.

We've got a touch of frost around first thing

:25:17.:25:18.

But things are gradually going to be warming up over the next couple

:25:19.:25:25.

Some decent spells of sunshine but equally there's a bit of rain

:25:26.:25:29.

in the forecast, especially for northern and western

:25:30.:25:32.

areas, but nowhere immune to rain at some point in the weekend.

:25:33.:25:34.

We have this front draped through parts of northern England,

:25:35.:25:37.

To the north of that in Scotland and much of Northern Ireland,

:25:38.:25:41.

after that chilly start to the morning, sunny spells first thing.

:25:42.:25:44.

Further south across the Borders into northern England,

:25:45.:25:46.

heavier bursts of rain over the hills and patchy rain affecting

:25:47.:25:49.

the western half of Wales and parts of Cornwall and west Devon.

:25:50.:25:53.

Moving our way further east across the bulk of England through

:25:54.:25:57.

the Midlands, East Anglia and the south-east, after that chilly start

:25:58.:26:00.

things will warm up nicely in the sunshine with a southerly breeze.

:26:01.:26:03.

Staying dry across the bulk up England through the day, the rain

:26:04.:26:06.

in the north edging further north into southern Scotland and Northern

:26:07.:26:08.

Ireland, raining in Belfast through the early part of afternoon.

:26:09.:26:11.

But the rain should gradually clear from Wales and the south-west of

:26:12.:26:14.

England and in the south we'll see dry and settled weather, 9-10 with

:26:15.:26:17.

the cloud and rain in the north but further south with the light winds

:26:18.:26:22.

and sunshine, 15 or so will feel very pleasant. Won't stay dry all

:26:23.:26:27.

Won't stay dry all the time in the south-east and

:26:28.:26:30.

we'll see a few showers later in the day.

:26:31.:26:32.

Premier League matches on Saturday, our featured games here should stay

:26:33.:26:35.

dry with sunshine and fairly light winds.

:26:36.:26:36.

It's not until the latter part of the afternoon we see the rain

:26:37.:26:40.

moving from the south affecting the London region, East Anglia, some

:26:41.:26:42.

uncertainty about the position and timing of this area of rain but it

:26:43.:26:46.

looks like it will move to the north-east of England through

:26:47.:26:49.

Sunday brings a few more more spells of rain in Scotland and

:26:50.:26:53.

Northern Ireland, perhaps later in the day a few showers for Wales

:26:54.:26:57.

Central and eastern areas will see the best of the dry weather

:26:58.:27:02.

on Sunday and with the southerly breeze it will feel warm, 17 or 18

:27:03.:27:05.

in the south, more like 11 for the likes of Belfast and Glasgow.

:27:06.:27:08.

For the Scottish Premiership action on Sunday,

:27:09.:27:12.

We could see some spells of rain, probably won't be raining all

:27:13.:27:19.

Things are looking fairly unsettled into the new working week.

:27:20.:27:28.

Low pressure dominates things heading into Monday,

:27:29.:27:29.

with a frontal system coming in from the south from France.

:27:30.:27:32.

Some spells of rain for central and eastern areas in particular through

:27:33.:27:35.

the day on Monday, northern and western parts of the UK staying a

:27:36.:27:38.

bit drier, still showers possible, temperatures not far off where they

:27:39.:27:41.

should be for the time of year with highs generally around 10-15.
