Unless you have a selfie stick or a longer than average arm, your selfies are sure to misrepresent or distort your facial features. Now, Princeton University has invented a tool that transforms photos to look like a professional photographer snapped them at a farther distance - for a more realistic shot. This editing technology can also alter an apparent pose as if the camera were placed higher, lower or at an angle for the perfect selfie to share online. Princeton University has invented a tool that transforms your original selfie (left) to look like a professional photographer snapped the image (right) at a farther distance. Princeton gathered the data from a database of 150 people that were each photographed in 20 different poses.

Online giant Amazon said it profit in the second quarter surged ninefold to 857 million, lifted by cloud services as the tech giant expanded its offerings. Revenues jumped 31 percent to 30.4 billion, Amazon said in stronger-than-expected results. While Amazon developed a reputation for delivering little or no profit in its retail operations, its earnings have been growing over the past year as it expands into video and new delivery services and boosts its cloud computing unit, Amazon Web Services (AWS). Revenues jumped 31 percent to 30.4 billion, Amazon said in stronger-than-expected results The second annual Prime Day was the biggest day ever for Amazon, and was also a record day for Amazon devices globally. Compared to Prime Day 2015, worldwide orders grew by more than 60%, orders from third-party sellers with Prime Day deals nearly tripled, and Prime members saved over twice as much on deals.

China has allocated 199 million yuan ( 29.76 million) to spend on its weather modification programme as part of efforts to combat drought and reduce the impact of natural disasters. The finance ministry revealed the project earlier this month, as state media reported flooding this year caused at least 237 deaths. The Ministry of Finance said the additional funding had been made available in order to help China's regions respond to the large number of'extreme weather events' this year, including heavy flooding in south and central regions as well as drought in the northwest.

Nasa has announced that it has found evidence of flowing water on Mars. Scientists have long speculated that Recurring Slope Lineae -- or dark patches -- on Mars were made up of briny water but the new findings prove that those patches are caused by liquid water, which it has established by finding hydrated salts. Several hundred camped outside the London store in Covent Garden. The 6s will have new features like a vastly improved camera and a pressure-sensitive "3D Touch" display

It may be many men's dream to have Scarlett Johansson tend to their every need. But one man has come close to making this fantasy a reality by building a look-a-like robot. He now plans on sharing his designs in a handbook, so other fans can create their own sexy androids too. The life-size robot was created by Hong Kong designer Ricky Ma, based on a famous Hollywood actress. A 3D-printed skeleton lies beneath Mark 1's silicone skin, wrapping its mechanical and electronic parts.

America's stealth submarines and being used to carry out cyberattacks and listen in on enemy computer networks, two US Navy officials have revealed. The secret offence capabilities were revealed at a recent Washington conference. 'There is a -- an offensive capability that we are, that we prize very highly,' said Rear Adm. Michael Jabaley, the U.S. Navy's program executive officer for submarines, at a Center for Strategic and International Studies event in Washington. It has previously been revealed the USS Annapolis (pictured) is among the submarines being used. 'This is where I really can't talk about much, but suffice to say we have submarines out there on the front lines that are very involved, at the highest technical level, doing exactly the kind of things that you would want them to do.'

Japanese scientists have unveiled a creepy humanoid robot that has complete control over its limb movements and facial expressions. The robot, 'Alter', is embedded with electronic sensors that mimic the neural network of the human brain. Alter's arms, head and facial expressions are controlled by these sensors, giving the robot a random pattern of movement eerily similar to a human's. Alter can even sing, converting the random movements of its fingers into a haunting synth melody. Alter is a humanoid robot designed by scientists in Japan.

Migratory birds use warm, rising currents of air to gain height using little energy to fly over long distances. But just how they navigate the height-boosting currents was a mystery, until now. Now, biologists have used mathematical models to demonstrate birds use'torque and vertical wind' to help them pick the most efficient soaring path through thermals. High fliers: Biologists have used mathematical models to demonstrate birds such as eagles (stock image) use'torque and vertical wind' to help them pick the most efficient soaring path through thermals Most migrating birds fly between 656 and 3,937 feet (200 to 1,200 metres) above sea level. When the wind s against them, they stay closer to Earth when obstacles like trees slow the wind down.

The idea of neural networks began unsurprisingly as a model of how neurons in the brain function, termed'connectionism' and used connected circuits to simulate intelligent behaviour .In 1943, portrayed with a simple electrical circuit by neurophysiologist Warren McCulloch and mathematician Walter Pitts. Donald Hebb took the idea further in his book, The Organization of Behaviour (1949), proposing that neural pathways strengthen over each successive use, especially between neurons that tend to fire at the same time thus beginning the long journey towards quantifying the complex processes of the brain. In 1950s, as researchers began trying to translate these networks onto computational systems, the first Hebbian network was successfully implemented at MIT in 1954. Around this time, Frank Rosenblatt, a psychologist at Cornell, was working on understanding the comparatively simpler decision systems present in the eye of a fly, which underlie and determine the its flee response. In an attempt to understand and quantify this process, he proposed the idea of a Perceptron in 1958, calling it Mark I Perceptron.
