Android mobiles outsell iPhones in the U.S for first time

0 comments

Mobile phones running Google's Android mobile operating system have surged past those of Apple's iPhone for the first time, according to new research.

The iPhone shook up the mobile phone industry when it was first introduced in 2007 and more than 50 million devices have since been sold.

Instead of having a screen with a separate keyboard, Apple introduced a mobile with one giant touchscreen. It was also the first to feature multitouch and a dedicated application store, with millions of games and tools.

Google, fearing they would be squeezed out of the mobile internet market, responded with their own software platform called Android.

This open-source software has been adopted by a number of phone manufacturers including Motorola, HTC, Samsung, Vodafone and Sony Ericcson. Google also sells its own smartphone, the Nexus One.

Now market research by the NPD group has revealed Android-powered mobiles are the second most popular category of smartphones in the U.S after Blackberry, according to market research by the NPD group.

They received 28 per cent of consumer sales in the first three months of this year, compared with 21 per cent for the iPhone.

Canada's Research in Motion, maker of the ever popular Blackberry, retained the top spot with 36 percent of sales.

Strong sales of Motorola's Android-powered Droid and HTC's Android-based Droid Eris were cited as among the reasons for Android's surge past Apple.

However, Apple are likely to pull ahead again with the expected launch of the Apple 4G iPhone at the Worldwide Developers Conference in San Francisco next month.

The NPD findings are based on the results of online consumer research surveys conducted each month. The sales figures do not include corporate or enterprise mobile phone sales.

'As in the past, carrier distribution and promotion have played a crucial role in determining smartphone market share,' said Ross Rubin, NPD's executive director of industry analysis.

This stunning picture is the first image of Earth ever taken from another planet that shows our home as a planetary disc, with the Moon in the distance.

Captured by Nasa's Mars Reconnaissance Orbiter as the spacecraft orbited the Red Planet, both the Earth and the Moon appear as crescents, engulfed in the vast darkness of space.

Our planet is captured in a 'half-Earth' phase, while the image also shows the Earth-facing hemisphere of the Moon.

Because the Earth and the Moon are closer to the Sun than Mars, they exhibit phases, just as the Moon, Venus, and Mercury do when viewed from Earth.

When the image was captured in 2007, Earth was 88million miles from Mars, giving the HiRISE image a scale of 88 miles per pixel.

Nasa could only picture the Earth and moon at full disk illumination when they are on the opposite side of the Sun from Mars. However, then the range would be much greater and the image would show less detail.

On the Earth image you can make out the west coast outline of South America at lower right, although the clouds are the dominant features.

This image required a processing, with the Moon image brightened so it would show up next to Earth.

How to build a time machine : STEPHEN HAWKING

0 comments

All you need is a wormhole, the Large Hadron Collider or a rocket that goes really, really fast

Stephen Hawking

'Through the wormhole, the scientist can see himself as he was one minute ago. But what if our scientist uses the wormhole to shoot his earlier self? He's now dead. So who fired the shot?'

Hello. My name is Stephen Hawking. Physicist, cosmologist and something of a dreamer. Although I cannot move and I have to speak through a computer, in my mind I am free. Free to explore the universe and ask the big questions, such as: is time travel possible? Can we open a portal to the past or find a shortcut to the future? Can we ultimately use the laws of nature to become masters of time itself?

Time travel was once considered scientific heresy. I used to avoid talking about it for fear of being labelled a crank. But these days I'm not so cautious. In fact, I'm more like the people who built Stonehenge. I'm obsessed by time. If I had a time machine I'd visit Marilyn Monroe in her prime or drop in on Galileo as he turned his telescope to the heavens. Perhaps I'd even travel to the end of the universe to find out how our whole cosmic story ends.

To see how this might be possible, we need to look at time as physicists do - at the fourth dimension. It's not as hard as it sounds. Every attentive schoolchild knows that all physical objects, even me in my chair, exist in three dimensions. Everything has a width and a height and a length.

But there is another kind of length, a length in time. While a human may survive for 80 years, the stones at Stonehenge, for instance, have stood around for thousands of years. And the solar system will last for billions of years. Everything has a length in time as well as space. Travelling in time means travelling through this fourth dimension.

To see what that means, let's imagine we're doing a bit of normal, everyday car travel. Drive in a straight line and you're travelling in one dimension. Turn right or left and you add the second dimension. Drive up or down a twisty mountain road and that adds height, so that's travelling in all three dimensions. But how on Earth do we travel in time? How do we find a path through the fourth dimension?

Let's indulge in a little science fiction for a moment. Time travel movies often feature a vast, energy-hungry machine. The machine creates a path through the fourth dimension, a tunnel through time. A time traveller, a brave, perhaps foolhardy individual, prepared for who knows what, steps into the time tunnel and emerges who knows when. The concept may be far-fetched, and the reality may be very different from this, but the idea itself is not so crazy.

Physicists have been thinking about tunnels in time too, but we come at it from a different angle. We wonder if portals to the past or the future could ever be possible within the laws of nature. As it turns out, we think they are. What's more, we've even given them a name: wormholes. The truth is that wormholes are all around us, only they're too small to see. Wormholes are very tiny. They occur in nooks and crannies in space and time. You might find it a tough concept, but stay with me.

Enlarge Time travel through a wormhole

A wormhole is a theoretical 'tunnel' or shortcut, predicted by Einstein's theory of relativity, that links two places in space-time - visualised above as the contours of a 3-D map, where negative energy pulls space and time into the mouth of a tunnel, emerging in another universe. They remain only hypothetical, as obviously nobody has ever seen one, but have been used in films as conduits for time travel - in Stargate (1994), for example, involving gated tunnels between universes, and in Time Bandits (1981), where their locations are shown on a celestial map

Nothing is flat or solid. If you look closely enough at anything you'll find holes and wrinkles in it. It's a basic physical principle, and it even applies to time. Even something as smooth as a pool ball has tiny crevices, wrinkles and voids. Now it's easy to show that this is true in the first three dimensions. But trust me, it's also true of the fourth dimension. There are tiny crevices, wrinkles and voids in time. Down at the smallest of scales, smaller even than molecules, smaller than atoms, we get to a place called the quantum foam. This is where wormholes exist. Tiny tunnels or shortcuts through space and time constantly form, disappear, and reform within this quantum world. And they actually link two separate places and two different times.

Unfortunately, these real-life time tunnels are just a billion-trillion-trillionths of a centimetre across. Way too small for a human to pass through - but here's where the notion of wormhole time machines is leading. Some scientists think it may be possible to capture a wormhole and enlarge it many trillions of times to make it big enough for a human or even a spaceship to enter.

Given enough power and advanced technology, perhaps a giant wormhole could even be constructed in space. I'm not saying it can be done, but if it could be, it would be a truly remarkable device. One end could be here near Earth, and the other far, far away, near some distant planet.

Theoretically, a time tunnel or wormhole could do even more than take us to other planets. If both ends were in the same place, and separated by time instead of distance, a ship could fly in and come out still near Earth, but in the distant past. Maybe dinosaurs would witness the ship coming in for a landing.

The fastest manned vehicle in history was Apollo 10. It reached 25,000mph. But to travel in time we'll have to go more than 2,000 times faster

Now, I realise that thinking in four dimensions is not easy, and that wormholes are a tricky concept to wrap your head around, but hang in there. I've thought up a simple experiment that could reveal if human time travel through a wormhole is possible now, or even in the future. I like simple experiments, and champagne.

So I've combined two of my favourite things to see if time travel from the future to the past is possible.

Let's imagine I'm throwing a party, a welcome reception for future time travellers. But there's a twist. I'm not letting anyone know about it until after the party has happened. I've drawn up an invitation giving the exact coordinates in time and space. I am hoping copies of it, in one form or another, will be around for many thousands of years. Maybe one day someone living in the future will find the information on the invitation and use a wormhole time machine to come back to my party, proving that time travel will, one day, be possible.

In the meantime, my time traveller guests should be arriving any moment now. Five, four, three, two, one. But as I say this, no one has arrived. What a shame. I was hoping at least a future Miss Universe was going to step through the door. So why didn't the experiment work? One of the reasons might be because of a well-known problem with time travel to the past, the problem of what we call paradoxes.

Paradoxes are fun to think about. The most famous one is usually called the Grandfather paradox. I have a new, simpler version I call the Mad Scientist paradox.

I don't like the way scientists in movies are often described as mad, but in this case, it's true. This chap is determined to create a paradox, even if it costs him his life. Imagine, somehow, he's built a wormhole, a time tunnel that stretches just one minute into the past.

Through the wormhole, the scientist can see himself as he was one minute ago. But what if our scientist uses the wormhole to shoot his earlier self? He's now dead. So who fired the shot? It's a paradox. It just doesn't make sense. It's the sort of situation that gives cosmologists nightmares.

This kind of time machine would violate a fundamental rule that governs the entire universe - that causes happen before effects, and never the other way around. I believe things can't make themselves impossible. If they could then there'd be nothing to stop the whole universe from descending into chaos. So I think something will always happen that prevents the paradox. Somehow there must be a reason why our scientist will never find himself in a situation where he could shoot himself. And in this case, I'm sorry to say, the wormhole itself is the problem.

In the end, I think a wormhole like this one can't exist. And the reason for that is feedback. If you've ever been to a rock gig, you'll probably recognise this screeching noise. It's feedback. What causes it is simple. Sound enters the microphone. It's transmitted along the wires, made louder by the amplifier, and comes out at the speakers. But if too much of the sound from the speakers goes back into the mic it goes around and around in a loop getting louder each time. If no one stops it, feedback can destroy the sound system.

The same thing will happen with a wormhole, only with radiation instead of sound. As soon as the wormhole expands, natural radiation will enter it, and end up in a loop. The feedback will become so strong it destroys the wormhole. So although tiny wormholes do exist, and it may be possible to inflate one some day, it won't last long enough to be of use as a time machine. That's the real reason no one could come back in time to my party.

Any kind of time travel to the past through wormholes or any other method is probably impossible, otherwise paradoxes would occur. So sadly, it looks like time travel to the past is never going to happen. A disappointment for dinosaur hunters and a relief for historians.

But the story's not over yet. This doesn't make all time travel impossible. I do believe in time travel. Time travel to the future. Time flows like a river and it seems as if each of us is carried relentlessly along by time's current. But time is like a river in another way. It flows at diff erent speeds in diff erent places and that is the key to travelling into the future. This idea was first proposed by Albert Einstein over 100 years ago. He realised that there should be places where time slows down, and others where time speeds up. He was absolutely right. And the proof is right above our heads. Up in space.

This is the Global Positioning System, or GPS. A network of satellites is in orbit around Earth. The satellites make satellite navigation possible. But they also reveal that time runs faster in space than it does down on Earth. Inside each spacecraft is a very precise clock. But despite being so accurate, they all gain around a third of a billionth of a second every day. The system has to correct for the drift, otherwise that tiny di fference would upset the whole system, causing every GPS device on Earth to go out by about six miles a day. You can just imagine the mayhem that that would cause.

The problem doesn't lie with the clocks. They run fast because time itself runs faster in space than it does down below. And the reason for this extraordinary e ffect is the mass of the Earth. Einstein realised that matter drags on time and slows it down like the slow part of a river. The heavier the object, the more it drags on time. And this startling reality is what opens the door to the possibility of time travel to the future.

Right in the centre of the Milky Way, 26,000 light years from us, lies the heaviest object in the galaxy. It is a supermassive black hole containing the mass of four million suns crushed down into a single point by its own gravity. The closer you get to the black hole, the stronger the gravity. Get really close and not even light can escape. A black hole like this one has a dramatic e ffect on time, slowing it down far more than anything else in the galaxy. That makes it a natural time machine.

I like to imagine how a spaceship might be able to take advantage of this phenomenon, by orbiting it. If a space agency were controlling the mission from Earth they'd observe that each full orbit took 16 minutes. But for the brave people on board, close to this massive object, time would be slowed down. And here the e ffect would be far more extreme than the gravitational pull of Earth. The crew's time would be slowed down by half. For every 16-minute orbit, they'd only experience eight minutes of time.

The Large Hadron Collider

Inside the Large Hadron Collider

Around and around they'd go, experiencing just half the time of everyone far away from the black hole. The ship and its crew would be travelling through time. Imagine they circled the black hole for five of their years. Ten years would pass elsewhere. When they got home, everyone on Earth would have aged five years more than they had.

So a supermassive black hole is a time machine. But of course, it's not exactly practical. It has advantages over wormholes in that it doesn't provoke paradoxes. Plus it won't destroy itself in a flash of feedback. But it's pretty dangerous. It's a long way away and it doesn't even take us very far into the future. Fortunately there is another way to travel in time. And this represents our last and best hope of building a real time machine.

You just have to travel very, very fast. Much faster even than the speed required to avoid being sucked into a black hole. This is due to another strange fact about the universe. There's a cosmic speed limit, 186,000 miles per second, also known as the speed of light. Nothing can exceed that speed. It's one of the best established principles in science. Believe it or not, travelling at near the speed of light transports you to the future.

To explain why, let's dream up a science-fiction transportation system. Imagine a track that goes right around Earth, a track for a superfast train. We're going to use this imaginary train to get as close as possible to the speed of light and see how it becomes a time machine. On board are passengers with a one-way ticket to the future. The train begins to accelerate, faster and faster. Soon it's circling the Earth over and over again.

To approach the speed of light means circling the Earth pretty fast. Seven times a second. But no matter how much power the train has, it can never quite reach the speed of light, since the laws of physics forbid it. Instead, let's say it gets close, just shy of that ultimate speed. Now something extraordinary happens. Time starts flowing slowly on board relative to the rest of the world, just like near the black hole, only more so. Everything on the train is in slow motion.

This happens to protect the speed limit, and it's not hard to see why. Imagine a child running forwards up the train. Her forward speed is added to the speed of the train, so couldn't she break the speed limit simply by accident? The answer is no. The laws of nature prevent the possibility by slowing down time onboard.

Now she can't run fast enough to break the limit. Time will always slow down just enough to protect the speed limit. And from that fact comes the possibility of travelling many years into the future.

Imagine that the train left the station on January 1, 2050. It circles Earth over and over again for 100 years before finally coming to a halt on New Year's Day, 2150. The passengers will have only lived one week because time is slowed down that much inside the train. When they got out they'd find a very diff erent world from the one they'd left. In one week they'd have travelled 100 years into the future. Of course, building a train that could reach such a speed is quite impossible. But we have built something very like the train at the world's largest particle accelerator at CERN in Geneva, Switzerland.

Deep underground, in a circular tunnel 16 miles long, is a stream of trillions of tiny particles. When the power is turned on they accelerate from zero to 60,000mph in a fraction of a second. Increase the power and the particles go faster and faster, until they're whizzing around the tunnel 11,000 times a second, which is almost the speed of light. But just like the train, they never quite reach that ultimate speed. They can only get to 99.99 per cent of the limit. When that happens, they too start to travel in time. We know this because of some extremely short-lived particles, called pi-mesons. Ordinarily, they disintegrate after just 25 billionths of a second. But when they are accelerated to near-light speed they last 30 times longer.

It really is that simple. If we want to travel into the future, we just need to go fast. Really fast. And I think the only way we're ever likely to do that is by going into space. The fastest manned vehicle in history was Apollo 10. It reached 25,000mph. But to travel in time we'll have to go more than 2,000 times faster. And to do that we'd need a much bigger ship, a truly enormous machine. The ship would have to be big enough to carry a huge amount of fuel, enough to accelerate it to nearly the speed of light. Getting to just beneath the cosmic speed limit would require six whole years at full power.

The initial acceleration would be gentle because the ship would be so big and heavy. But gradually it would pick up speed and soon would be covering massive distances. In one week it would have reached the outer planets. After two years it would reach half-light speed and be far outside our solar system. Two years later it would be travelling at 90 per cent of the speed of light. Around 30 trillion miles away from Earth, and four years after launch, the ship would begin to travel in time. For every hour of time on the ship, two would pass on Earth. A similar situation to the spaceship that orbited the massive black hole.

After another two years of full thrust the ship would reach its top speed, 99 per cent of the speed of light. At this speed, a single day on board is a whole year of Earth time. Our ship would be truly flying into the future.

The slowing of time has another benefit. It means we could, in theory, travel extraordinary distances within one lifetime. A trip to the edge of the galaxy would take just 80 years. But the real wonder of our journey is that it reveals just how strange the universe is. It's a universe where time runs at different rates in different places. Where tiny wormholes exist all around us. And where, ultimately, we might use our understanding of physics to become true voyagers through the fourth dimension.

New York police defuse car bomb in Times Square

0 comments

Police evacuated New York's famous Times Square early this morning after a dark-colored sports utility vehicle was seen smoking and a small 'flash' was observed by firefighters on the scene.

Officers at the scene said the evacuation order stemmed from an 'emergency investigation' and dozens of officers blocked access to the busy central Manhattan square, which is popular with tourists and theater-goers. It's three miles north of the World Trade Centre site, where the atrocities of September 11, 2001, were carried out.

New York Police Department spokesman Paul Browne said a vehicle had been left in Times Square, with smoke seen coming from it. It was discovered to contain explosives and a timing device.

'It appears to be a car bomb left in a Pathfinder between Seventh and Eighth (avenues),' he said at 6am GMT, adding that the device contained 'explosive elements' that included 'propane tanks, some kind of powder, gasoline and a timing device'.

Both US President Barack Obama and New York City Mayor Michael Bloomberg praised police for their quick response.

'We are very lucky,' Mr Bloomberg told reporters. 'Thanks to alert New Yorkers and professional police officers, we avoided what could have been a very deadly event.'

He said the bomb 'looked amateurish' but could have exploded, adding that the incident was a 'reminder of the dangers that we face'.

Kevin Barry, a former supervisor in the New York Police Department bomb squad, told the New York Times he was told it was an improvised explosive device. But somehow, he said, the ignition source 'failed to function the main charge'.

The vehicle's registration plates belonged to a different vehicle, police said.

A New York City firefighter who said he arrived early on the scene described the vehicle as a dark-colored SUV, and said it was parked at the corner of 45th Street and Seventh Avenue.

He confirmed the vehicle was smoking and also said he saw 'a flash' from the back of the SUV. The firefighter said a 'mini-explosion' occurred between 6pm and 6.30pm.

'The SUV was smoking. There was a flash and we put two and two together' and an evacuation was ordered, he said.

Other emergency personnel on the scene called the incident a 'car fire'.

The firefighter said the bomb squad remained at the scene as of 9pm, including a firefighter in a bomb suit. A robot was being used to investigate the suspicious SUV.

Reuters reporters on the scene said they heard an explosion from the area of the SUV around 9.15pm.

Two fire trucks were also at the scene, prepared to douse the vehicle with water if needed, the firefighter said.

Police said they planned to 'close down' Broadway shows in the vicinity, but it was not clear whether any theaters had actually been evacuated.

The square itself was mostly evacuated by 8pm according to Reuters reporters on the scene. Police had evacuated an area stretching from about 42nd Street up to 47th Street and including Seventh Avenue and Broadway.

But people dining inside the Blue Fin restaurant in a hotel at 47th and Broadway were allowed to continue and some people were being allowed in Broadway theaters in the area.

Police officers earlier told Reuters the area was shut down due to 'an emergency investigation'.

The rise of the robo-fighters: Britain's new pilotless air force

0 comments

The Mantis can fly for 24 hours without refuelling, do the surveillance job of four helicopters, acquire its own enemy targets and deliver a deadly payload - all without a pilot and crew. But should we be afraid of Britain's new robotic air force?

The Mantis

The Mantis carries no human crew. The plane is controlled by a set of computer components not that far removed from the chips and boards inside a high-end personal laptop

The aircraft is the size of a medium range bomber, with huge grey wings stretching 70ft across the hangar. It looks for all the world like any conventional aircraft - the wings, the nose, the wheels are all familiar. The engineers standing in front of it are dwarfed by its bulk. Modules beneath the wings can carry air-to-ground missiles and precision-guided bombs.

Other racks on the nose can carry surveillance equipment so advanced it can decrypt and listen to mobile phone messages instantly as it flies over, at heights of up to 60,000ft. It takes a while for you to notice the most important fact - there is no cockpit. There are no windows anywhere on the craft, - and no doors.

The Mantis carries no human crew - one of the reasons it can stay airborne for 24 hours. The plane is controlled by a set of computer components not that far removed from the chips and boards inside a high-end personal laptop. But unlike the American Predator and Reaper drones now flying over Afghanistan and Pakistan, this isn't flown by pilots via satellite control from a bunker outside Las Vegas. It flies itself.

The aircraft is sitting in the hangars of BAE Systems, just outside Preston - next to an airfield where Eurofighters are shooting vertically upwards from a take-off strip. The site is vast, with limousines ferrying suited executives from one part to another, and visitors carefully shepherded only into the areas they are cleared to see.

To enter Mantis's hangar, you have to pass through a glass cubicle that scans for any transmitting equipment - phones and cameras are strictly forbidden. A recording suddenly blares, 'Mobile phone detected!' as one of my hosts remembers he has a BlackBerry in his coat. I'm allowed to see Mantis, but not to know where the aircraft is currently flying.

The Mantis on the runway

The Mantis on the runway

Mantis isn't a 'drone'. It's a robotic aircraft. It's among the first of a new breed of armed UAV (unmanned aerial vehicle) that can take off , fly, plot courses and even acquire targets for itself, and the UK is at the forefront of this new technology. The Mantis only needs human beings for one thing - to pull the trigger.

The wars in Iraq and Afghanistan - with their political pressure for low casualties - have caused an explosion in demand for craft that need less and less human input. The spectacle of captured pilots was a staple of the first Iraq war and other conflicts around the Middle East. It's a vision that has been absent from the news this time round for one simple reason: there are now fewer pilots.

Robotics is a revolutionary technology on a par with gunpowder and the atomic bomb. It's another genie you couldn't put back in the bottle

Laptop parts, satellite connections and software are doing it instead. There are now 12,000 UAVs, used for everything from surveillance to search and destroy missions. In less than a decade, the business of unmanned aircraft has gone from being a minor, specialist sector to being worth £9 billion.

In the training missions that BAE is allowed to discuss with me, Mantis takes off entirely independent of its crew. When airborne, it is controlled either from a base in the UK or from a command-and-control centre so tiny that it fits inside a packing crate, which can be flown to a combat theatre inside a transport aircraft, with a commander and crew ready to deploy.

A satellite relays information to the Mantis, while pictures, video feeds, infrared images and decrypted phone calls come back from the battlefield. Six screens back on the ground off er a Mantis-eye view, a map and a set of geometric patterns showing the Mantis's orders.

Identifying potential targets

Identifying potential targets

Previous generations of surveillance craft deluge intelligence staff with so many pictures that up to 160 back-room staff are required for each aircraft, but Mantis decides for itself what is interesting. A single Mantis can do the surveillance job of three or four helicopters or three Nimrod jet crews.

While it's in flight, no one controls Mantis with a joystick. Details of the mission are copied on to a memory stick and loaded into the control system's computers by the commander. In training two Mantis operatives can oversee up to three aircraft at once.

A video of BAE's software in action shows the aircraft targeting a line of trucks from miles above the Australian outback, with squares appearing over vehicles showing that they are objects of interest while Mantis flies over to investigate. The software inside Mantis has decided that they are moving, that they are in an area they shouldn't be and that they match its criteria for further investigation.

For a terrorist, or a lone psychopath, the idea of a vehicle that could launch, find targets and attack autonomously must seem like the ultimate risk-free weapon - a suicide bomb without a suicide bomber

Until now, the British Army has relied on American and Israeli drones, but Mantis is home-grown technology. In just four years the Mantis family of aircraft has gone from laptop components strapped to a second-hand glider bought in Wolverhampton to an operational spy plane due to enter full service in 2015.

The process has cost £124 million, and development has been spread across a team of British companies, including Rolls-Royce and QinetiQ, and British universities, such as Loughborough. At least two Mantis planes are being tested in the air right now over combat zones, although BAE is not allowed to say where. Other drone companies such as Boeing, Northrop Grumman and Lockheed Martin are making their own autonomous versions - but none can match demand.

Autonomous machines save money, save pilots' lives and point to a future where stealth-enabled unmanned fighters and ultra-long-endurance surveillance planes can almost remove human beings from the aerial battlefield. But this technology has largely appeared without governments or the public questioning it. Can a chip make split-second decisions as well as a highly trained pilot? What happens when these systems fail? And worst of all - what happens when one falls into the wrong hands?

Unmanned aircraft have been used routinely since World War II, when the Germans used a remotely piloted bomb drone known as the 'Fritz'. But the market has exploded in the past ten years. There are 43 nations currently developing their own unmanned vehicles, including China, Iran and Russia. Some predict-that the market will hit a value of £53 billion - and the U.S. Army already predicts that its air force will be 80 per cent robotic by 2020.

Although drones are widely used, air forces tend to be nervous about letting them fly under their own steam - so highly trained pilots are still used, with a full back-up staff to ensure that nothing goes wrong.

'The way the U.S. military likes to do things, current attack drones require up to three pilots to operate - fastjet combat pilots, who are rare and expensive front-line assets,' says Steve Worsnip of BAE Systems. 'But the RAF doesn't have the luxury of those sort of numbers. They simply can't fight wars that way.'

'The human role isn't disappearing, but it is changing,' says PW Singer, a former Pentagon weapons adviser and author of Wired For War: The Robotics Revolution And Conflict In The Twenty First Century, 'Humans are no longer making decisions in the here and now; rather, they are simply supervising.'

In the U.S., more drone pilots are now being trained than actual pilots - and the degree of autonomy exhibited by the aircraft has increased to the point that new controllers don't even need to know how to fly. Many are videogamers, more than ready for the dehumanised, computer-assisted world of drones.

'People have an inherent fear of autonomous aircrafts, but as we face technical and battlefield problems, the solution is more and more autonomy,' says Singer.

'One of the problems right now is that unmanned systems such as Predator are gathering enormous amounts of data. We're about to add "Gorgon Stare" to Predators - an array of 12 video feeds. We can't keep up, but give the sensors more autonomy and they will decide what they send. A lot of the scientists told me that robotics is a revolutionary technology on a par with gunpowder and the atomic bomb. It's another genie you couldn't put back in the bottle.'

The BAE Mantis isn't the only unmanned aircraft that can operate independently. Global Hawk RQ-4, made by Northrop Grumman, is a huge, high-altitude craft that has been flying over Afghanistan for a decade, and has no need for pilots, either in the air or on the ground. It was the first unmanned vehicle capable of flying itself, and has completed more than 30,000 combat hours overseas. Its makers seem off ended by the use of the word 'drone' and refer to it as a 'robotic aircraft'.

Twelve years ago, a prototype of the RQ-4 Global Hawk was flying at 60,000ft above the Atlantic Ocean, near the east coast of the Azores. Its flying altitude is almost double the ceiling of civilian aircraft, and one of the reasons the Global Hawk is cleared to fly over civilian airspace. Abruptly, the 'crossover' between two of the military satellites used to guide the Hawk failed, due to human error.

This was what its autonomy software had been designed for - 'contingencies' are programmed into its software so that it can respond to unforeseen events. The Hawk turned itself around, entirely without satellite guidance, and returned to the airbase it had flown from. Ten minutes later, it landed at the base.

'Our first fully autonomous landing was in 1975,' says Dane Marolt, international business development director of the RQ-4, a former pilot who has overseen Northrop Grumman's autonomous drones programme since it first began.

'The RQ-4 is totally autonomous. It is a mouse-click aircraft. But there is no pilot flying this. As it stands, the U.S. Army and Navy choose not to use it in this way - there is a pilot in command.'

Every weapons company says the same thing - that it is their computer software that gives them the edge. The equipment inside the UAVs may not be cutting-edge, but the software is. And this software isn't as easy to protect, or to copyright, as a vehicle. It's also much more easily copied. Hezbollah has already fired captured drones back at Israel from the West Bank. There are other risks, too - last year, insurgents hacked into the video feeds of Predator drones flying over Iraq.

The website DIY Drones is a thriving community of do-it-yourself drone builders and operators, building drones that look eerily similar to - or are copies of - the weapons employed currently by the West. For a terrorist, or a lone psychopath, the idea of a vehicle that could launch, find targets and attack autonomously must seem like the ultimate risk-free weapon - a suicide bomb without a suicide bomber.

Autonomy is far more ubiquitous than people think, but it brings with it problems and dangers. The AEGIS shipboard computer used on board American destroyers controls their anti-missile systems. It works so quickly that operators simply tell it whether to shoot fighters or bombers first when the ship comes under attack - the ship then acquires targets and shoots on its own. It was an AEGIS system that had been left in attack mode that shot down an Iranian airliner in 1988. The system had mistakenly identified it as an enemy fighter.

But while mistakes of that magnitude are rare, a report, The Year Of The Drone, by the New America Foundation, an American non-profit think tank, has analysed drone strikes against militants in Pakistan and has found that the level of civilian casualties was such that it undermined any claims of drones being 'precision' weapons. The use of weaponised drones might have reduced the number of captured pilots - but their capacity to strike precisely is questionable.

'Our research shows that some two-thirds of those killed in the strikes since 2004 have been described as militants, implying a civilian casualty rate of about one-third,' says the foundation's Katherine Tiedemann.

Philip Alston, the UN's Special Rapporteur for Extrajudicial Executions, alleges that the use of drones over states such as Pakistan, with which the US has not declared war, 'might violate international humanitarian law and international human rights law'.

President Obama's State Department legal adviser Harold Koh replied to Alston's allegations saying, 'Our procedures and practices for identifying lawful targets are extremely robust, and advanced technologies have helped to make our targeting even more precise.'

Earlier this month, a drone strike on Boya village, in Pakistan's North Waziristan, killed between three and five Al-Qaeda militants, according to reports, but also up to 13 civilians. Human Rights Watch is trying to open debate on the use of the weapons in Afghanistan and Pakistan. The statistics in The Year Of The Drone allege that more than 400 civilians have been killed by drones in Pakistan in just one year - and its authors allege that the U.S. government is not open about the casualties.

'The closest a government official has come to publicly recognising the civilian casualties is an anonymous quote suggesting that only 20 civilians have been killed in drone strikes in Pakistan in the last two years,' says Tiedemann. But still the drive among the West's armies is to allow not more control over UAVs, but less.

Harrier II and Mantis specs


Boeing, like BAE, is already developing unmanned aircraft that will go well beyond its current roles of surveillance and attacking ground troops. Boeing and BAE's unmanned planes look and operate like stealth bombers - a role in which communication with the outside world is likely to give away a plane's decision.

At BAE the black, triangular shape of Tanaris looks instantly familiar - it's almost identical to the American B-2 stealth bomber. It's a UAV designed for a different kind of warfare - not against tribesmen armed with AK-47s but against modern nations equipped with radar, satellites and electronic counter-measures. To maintain full stealth cover, it is capable of severing communications with its handlers and travelling without radio contact for up to 36 hours.

Tanaris is a so-called 'black project' - it's introduced as a model in a room at BAE's headquarters in Preston, and the three senior managers who introduce it are deliberately vague about where Tanaris might be used, what weapons it might carry, or any context in which it might be deployed. Tanaris will take its first flights next year and is a 'test-bed' for future technologies. Some of the technologies inside Tanaris will be used in MoD vehicles until 2025.

'One of the critical ways UAVs will improve is by staying up in the air longer - current models can only remain airborne for around 80 hours,' says the University of Reading's Kevin Warwick.

'The American military research organisation Darpa has put out a contract called Vulture looking for a solar-powered UAV that can remain airborne for five years. On the more micro scale, UAVs will have a role flying in and out of buildings. They'll also continue to become more autonomous. "Drone" makes it sound quite friendly and politically digestible. These aren't drones. They're hunter-killers. Other systems in development might work as "swarms", communicating with one another to carry out the mission.

'That's the worry - they make the decisions. What are these decisions? If it's against the enemy, it's fine - but what happens if it decides that I'm the enemy?'

Gordon won't be getting my vote: Gillian Duffy reveals what REALLY upset her about that devastating exchange with PM

0 comments

The woman branded a ‘bigot’ by Gordon Brown launched an outspoken attack on the Prime Minister last night, as a new poll showed David Cameron on course to win the Election, but with too few MPs to rule on his own.

Rochdale grandmother Gillian Duffy, whose encounter with Mr Brown threatens to turn a Labour defeat into a rout, told the Prime Minister she pitied him and said his days in Downing Street were numbered.

What hurt her most of all was not the word ‘bigot’, but the way he referred to her as ‘that woman’.

Speaking exclusively to The Mail on Sunday, Mrs Duffy, right, said: ‘I’m not “that woman”. It’s no way to talk of someone, that, is it? As if I’m to be brushed away. Why couldn’t he have said “that lady”?’

Nor was Mrs Duffy impressed when he came to her house, made a grovelling apology and invited her to No10 to visit him and his wife Sarah.

‘He asked, “Do you ever come down to London? If you ever come down you must come to No10 and meet me and Sarah,”’ Mrs Duffy revealed. ‘Well, I just looked at him. I didn’t like to say it, but all I could think was, “I don’t think you’ll be there.”’

In spite of the Prime Minister’s attempt to make amends, lifelong Labour supporter Mrs Duffy says she will not vote for Mr Brown – or indeed for any other party – on Thursday. She was so disgusted by the Prime Minister’s conduct that she threw away her postal voting form.

Her hard-hitting comments come as a BPIX survey for The Mail on Sunday underlines the extent of the damage caused to Labour by the so-called ‘Bigotgate’ affair – sparked when unguarded comments Mr Brown made after meeting Mrs Duffy were caught on a microphone that he had forgotten to remove.

The poll puts the Conservatives on 34 per cent, with the Lib Dems on 30 and Labour trailing a poor third on 27. The ratings are not enough to secure outright victory for Mr Cameron, although two other polls showed him closer to the winning line.

In her interview with The Mail on Sunday, widowed Mrs Duffy, 65, who has been honoured for her 30 years’ work with special needs children, spoke of her shock and sadness at being ‘shot down’ by a man and a party she had believed would support her.

She described how she refused to be drawn into a staged handshake with Mr Brown for the TV cameras on her doorstep. And she said Mr Brown should never have succeeded Tony Blair without a mandate from the electorate.

‘All I did was ask what was on my mind and the questions that most people want to have answered. Does that make me a bigot? I think Gordon would like to just forget about it and move on but it’s not as easy as that.

‘Sorry is a very easy word. I’m not voting this year. I’ll cast my vote in the local council elections but not the General Election.

‘Gordon Brown was Chancellor of the Exchequer, he should be able to answer questions about the economy, shouldn’t he? But he can’t. If you say you want to go out and meet the people you should have some answers.’

During the 45 minutes that the Prime Minister spent eating humble pie in Mrs Duffy’s sitting room, she quizzed him again, asking about issues including the national debt, benefits, tax credits and immigration.

We're working three more days for the taxman: It takes 149 days of earning in a year before our income is our own

Clutching you cash: The taxman

Clutching you cash: The taxman

Britons will have to work three days longer this year before they start earning money for themselves rather than the government.

Tax Freedom Day will fall on May 30 - 149 days into 2010 - according to the free-market think tank the Adam Smith Institute.

It said the three-day increase on 2009 was largely because of the rise in VAT from 15 per cent back up to 17.5 per cent at the beginning of the year.

If the budget deficit was all funded from tax - rather than with the help of loans --then Tax Freedom Day would shift back to July 8, pointing to Britain's worst fiscal position since 1976.

Tom Clougherty, executive director of the institute, said: 'Our Government relies so much on debt to fund spending that our traditional Tax Freedom Day measure makes them look more virtuous than they actually are.'

Of the 149 days, 41 is taken up by income tax, followed by National Insurance at 27 days.

It takes a further 21 days to cover all of the VAT the average Briton will pay this year, while the various different excise duties account for 13 days.

Council tax costs the equivalent of seven days' pay, with stamp duty accounting for three days' worth, and a further 18 days to cover a range of miscellaneous taxes.

China celebrates the start of Shanghai World Expo 2010 with incredible opening ceremony

0 comments

Shanghai celebrated the opening of the 2010 World Expo today with a lavish display of fireworks, fountains and laser lights.

Like the 2008 Beijing Olympics, the event showcased China's growing economic and geopolitical sway.

In a toast at a gala dinner for dignitaries invited to watch the ceremony, President Hu Jintao said he was confident the world would 'witness a successful, splendid and unforgettable World Expo.'

The star-studded indoor festivities included action star Jackie Chan, Japanese singer Shinji Tanimura, concert pianist Lang Lang and opera star Andrea Bocelli among the 2,300 performers.

Afterward, guests moved outside for a lights, music and fireworks jubilee that lit up the banks of the Huangpu river with 1,200 searchlights, powerful lasers and mobile fountains.

The waters glowed with 6,000 rosy-hued LED balls and lights from a parade of flag boats representing nations participating in the Expo.

The Expo, which opens to the public tomorrow, is expected to draw 70 million people over six months to pavilions from almost 200 nations designed to reflect the urban sustainability theme of 'Better City, Better Life.'

From the United States to North Korea, a total of 189 countries will have exhibitions at the six-month event that is expected to attract up to 100 million visitors

China is spending $4.2billion on the Expo itself, and much more on other improvements for Shanghai.

It is the most expensive and largest Expo to date, and local media have reported the true cost is closer to $58 billion, including infrastructure.

'This is a very important moment. We have made preparations for years,' Hong Hao, Deputy General for the Expo, said.

Freshly painted buildings, new highways, subway lines and airport terminals all proclaim the country's newfound status as a modern, increasingly affluent industrial giant.

Zheng Yongnian, director of the East Asian Institute of the National University of Singapore, said: 'The government will spend whatever money it takes. For the leadership, it's worthwhile.'

The Expo completes a trio of landmark events that began with the Olympics and was followed by the elaborate military parades for the 2009 celebration of the 60th anniversary of Communist Party rule.

All have involved massive security crackdowns, although commercial-minded Shanghai has kept measures relatively low-key compared to the lockdown imposed for the Beijing Olympics.

'Of more concern would be bird flu or H1N1. If that breaks out on site, how will they manage to prevent it spreading and how will they attempt to quarantine such a large number of people?' said Greg Hallahan, regional director at business risk consultancy PSA Group in Shanghai.

Still, local authorities, determined to prevent crimes or disturbances that could affect the Expo, have tightened their enforcement of a ban on protests or public criticism of the ruling Communist Party.

Prominent dissident Feng Zhenghu said police confiscated computers from his home after he announced a new manifesto on human rights, a critique of Shanghai's legal system, to coincide with the Expo.

Meanwhile, the Hong Kong-based Chinese Human Rights Defenders said at least six people who protested having their homes demolished to make way for the Expo were sent to labour camps.

The Shanghai Expo, the first held in a developing country, is a source of pride for many city residents, though they already are complaining about crowds, traffic jams and other disruptions.

The already tight security in the city was increased today as authorities closed the sprawling riverside Expo site to all but a few workers, journalists, and VIPs.

As the evening performance began, police went from door-to-door in some buildings near the Expo site, trying to force visitors to leave as outraged residents argued back.

'We have been bothered many times recently. They even don't allow us to invite our relatives or friends to come see the fireworks. How can such a good thing turn out to be so be miserable?' complained one apartment owner.

Shanghai residents had crowded into areas near the river from the early afternoon, hoping to get a glimpse of the evening celebrations attended by Hu and other leaders.

China's relations with the outside world have been strained of late, with issues like the value of the yuan currency, a fight over censorship with Google and the trial of four Rio Tinto executives casting a pall over the country's efforts to present itself as a respected international player.

Leaders including French President Nicolas Sarkozy, Russian President Dmitry Medvedev, South Korean President Lee Myung-bak and EU Commission President Jose Manuel Barroso were at the opening ceremony today.

Smaller countries, such as Israel, are also making efforts to engage China through the Expo, despite the shadow cast by the financial crisis.

Yaffa Ben-Ari, deputy commissioner general of Israel for the Shanghai World Expo, said the Jewish state aimed to boost cooperation through the event.

The elaborate outdoor performances, focused on the themes Welcome to China, Harmonious Gathering and Celebration were centered on what organizers said is the world's largest LED screen, at 920ft long and 108ft high, and a fountain shooting water 262ft high.

David Atkins, the executive producer of the outdoor performance, said: 'This show couldn't be done anywhere but in China.'

The project has not been without its detractors. Rights groups have complained about evictions of residents to make way for the two spectacular main Expo sites on either side of the murky Huangpu River.

Some Chinese have also wondered why the country, with its growing rich-poor gap, severe environmental and other problems is spending so much on an event which lacks an Olympics' cachet.

'Our living costs are five times yours but our salaries are one fifth of yours. Yet we survived and we are still joyfully and happily welcoming friends from all around the world,' wrote popular Shanghai blogger Han Han, with a strong sense of irony.
