The Pentagon may scrap a $3.5 billion warship despite having already built half of it. In a shock turnaround, the USS Lyndon B Johnson may be dropped from production in just a few weeks as the Defense Department tightens its purse strings. It would be an embarrassing anti-climax for the Pentagon after years of hype surrounding the third and final Zumwalt-class destroyer which is 41 per cent complete and was tipped to transform the US Navy's fleet.
Dutch scientists create £20m tsunami generator to boost low-lying country's defences.
The software will be available to download on the iPhone 4s and later, iPad 2 and later, the iPad mini and later models and the fifth-generation iPod touch.
Mystery of the caverns littered with Bronze Age children's decapitated heads: Gruesome find in grounds of Prince Charles's old school in remote Scotland
Archaeologists made the grim discovery in a remote part of the estate of Gordonstoun near Inverness, whose former pupils also include five of the Queen's children and grandchildren. The cave (above), looking out from sea cliffs over the Moray Firth, was apparently used in funeral rituals from 1100 BC to 900 BC by the Pictish clans ruling Scotland at the time. Experts say the clans placed bodies in the cave to decompose so that bones could eventually be retrieved. They also say there are indications that it was later used for executions. Also pictured (inset): A Pict carving found inside.

The airbag for a BULLET: Ping pong ball-style cushion can be attached to any gun to slow down shots and prevent fatal injuries
The device (pictured), designed by Alternative Ballistics in San Diego, California, takes the form of a metal ball or 'bullet capture device' that is fitted over the barrel of a gun. Once the gun is fired, the bullet embeds itself inside the device without a chance of it escaping.The bullet's energy is simultaneously transferred to the alloy ball, propelling it towards the target. 'The Alternative' works like an airbag for a bullet, slowing it down to one fifth of its intended speed.
Striker II takes to the skies: Advanced helmet uses a night vision camera to help fighter pilots fly under the cover of darkness
Farnborough-based BAE Systems has begun night trials (pictured bottom left) on the Striker II helmet-mounted display (pictured right) in the hope they will lead to a fully integrated digital night vision helmet to replace the heavy goggles currently worn by pilots. Heavy night vision goggles currenly worn increase G-force pressures on the head and neck, limiting the pilot's manoeuvrability in the cockpit. Striker II includes a cutting-edge tracking system that ensures the pilot's exact head position (pictured top left) and the aircraft computer system are continuously in sync, reducing problems common to other HMD's.
Porsche unveils its Tesla killer: Mission E can be charged simply by driving over a special tile and has a holographic dashboard controlled just by LOOKING at it
Porsche boasts it's new Mission E concept has all-wheel drive and all-wheel steering, zero to 100 km/h acceleration in under 3.5 seconds and a charging time of around 15 minutes to reach an 80 per cent charge of electrical energy. It charges using special conductive tiles the owner simply drives over.
Seen a shooting star? It may have been HUMAN WASTE: Nasa reveals astronauts create 180lbs of excrement each year that burn up in the atmosphere
American Astronaut Scott Kelly (pictured bottom right) began the 'A Year in Space' mission by blasting off from Baikonur in Kazakhstan in a Soyuz vehicle in March and is now half way through his stay on the ISS. To celebrate this milestone, Nasa has produced an infographic (pictured left) detailing some of the stranger effects microgravity will be having on Kelly's body. They include the fact the astronaut will produce around 180lbs (82kg) of faeces that will burn up in the atmosphere and look like shooting stars.
Is this the saddest polar bear on the planet? Photo showing plight of emaciated animal as she drags her injured leg across the ice is shared 41,000 times
Nature photographer Kerstin Langenberger, who is based in Germany, posted the image of the 'horribly thin' injured bear on Facebook last month, and it has now been shared more than 41,000 times. The photo was taken in Norway's Svalbard region, a group of islands in the Arctic Ocean where tourists often go to see polar bears in their natural habitat. She claims the picture is also evidence of the retreating sea ice, which she thinks is affected by global warming. Females are particularly affected as they tend to stay on the pack ice with their young and have an increasing struggle to find food, she wrote.
Medieval skeleton 'bursts from the earth': Remains are snapped in two as storm rips tree roots containing the bones into the air
Half of the skeleton was found trapped in the roots of a birch tree (pictured bottom right) in Collooney, Sligo in Ireland, which blew over in the winter storms of last year (top right). The skeleton was snapped in two and the leg bones (left) remained in the grave. The skeleton has since been analysed and belongs to a young medieval man who probably died a violent death in the 11th or 12th century.
Luke Skywalker's prosthetic arm is REAL: Robotic limb allows a patient to feel what it touches through a microchip in their brain
Scientists at the University of Miami working with Darpa have developed a robotic arm (pictured) that can allow patient's to'feel' by sending tiny electrical signals to an implant in their brain. It has allowed a 28-year-old man called Nathan to feel researchers touching his fingers in a natural way. The technology mirrors the prosthetic arm given to Luke Skywalker after he gets his hand cut off in the Star Wars film The Empire Strikes Back (bottom right).
Watch the world's biggest wave machine in action: £20m tsunami generator could save Holland from floods
Dutch scientists have created the world's biggest man-made wave as part of a multi-million pound project aimed at helping to save the low-lying country from devastating floods. The highest artificial wave generated so far is just over 5 metres but engineers are hoping to produce even larger ones at the newly-completed 26million euro facility. Holding 9 million litres of water, pumped in from a reservoir at 1,000 litres a second, the Delta Flume produces waves by pushing water back and forth against a 10m-high steel wall, with scientists able to create a range of conditions from choppy waters, to rough seas and even a single tsunami wave.
Neanderthals are almost TWICE as old as first thought: DNA suggests extinct human species emerged 700,000 years ago
Geneticists at the Max Planck Institute for Evolutionary Anthropology in Germany have obtained the oldest genetic information from an early species of human to ever be sequenced. Analysis of the DNA has confirmed the fossils (pictured), which were found in a cave in the Atapuerca Mountains in Burgos, Spain (shown on the map inset), belonged to early Neanderthals. Scientists had previously believed the species first appeared 400,000 years ago, but the new results suggest they could be up to 765,000 years ago, according to the scientists.
Folding robo-legs let helicopters touch down ANYWHERE: Joints could help pilots land on rocky mountains and moving boats
Engineers at Darpa and Georgia Tech have designed Robotic Landing Gear, which comprises four articulated legs that can bend and fold beneath the fuselage so it can land on uneven surfaces (screenshot). It's hoped the prototype system may one day enable helicopters to land in remote and rocky locations to rescue people stranded on mountains, in disaster zones and on large boats (illustrated inset) for example.
Watch the raw power of a TASER in slow motion: Video reveals rippling skin as volunteer spasms and howls in pain
YouTubers the Slo Mo Guys visited Taser International in Scotsdale, Arizona, to film a Taser being fired at a volunteer at a rate of 28,500 frames per second (pictured). The video shows the Taser's two probes puncturing the skin and his muscles involuntarily rippling as the device stimulates his sensory and motor nerves, causing him to howl in pain and shock.
