Smart car rear-view mirror makes passengers disappear

A new magic rear-view mirror makes passengers and other objects inside a car disappear, giving the driver a perfect view of what he otherwise might not see behind him. The mirror uses four cameras installed around a car to offer a virtual bird's-eye view for parking and navigating tight spaces and offers an enhanced view in bad weather. A small camera mounted behind the rear window, positioned where the wiper can keep it clean, sends a feed to a video monitor embedded in the mirror housing. The driver toggles a switch between the mirror and the camera display much as they change a conventional mirror from day to night settings, 'Fox News' reported. The Smart Rear View Mirror developed by Japanese automotive manufacturer Nissan provides a field of vision that matches up almost precisely to the mirrored surface, but the picture can be adjusted for height, zoom and brightness. The mirror is designed to be used on the move, not just while parking, the company said.

Dinosaur-inspired robot sprints faster than Usain Bolt

Researchers have created a new sprinting robot, inspired by a ferocious dinosaur, which is so fast it can outrun Usain Bolt. The robot, called Raptor, has achieved a speed of 46 kilometres per hour on a treadmill. That is faster than the fastest human, the Olympic sprinter Usain Bolt, whose top speed has been estimated at 43.92 km/h. Built by researchers at the Korea Advanced Institute of Science and Technology, the robot has two nimble legs and a mechanism that mimics a tail. Raptor is almost as fast as the world's fastest legged robot, Cheetah, built by Boston Dynamics, which reached 47 km/h in a trial two years ago, also on a treadmill, IEEE Spectrum reported. Inspired by the velociraptor a predatory dinosaur which lived 75 million years ago Raptor is a compact, 3-kilogramme machine, with legs made of lightweight composite material.

New smartphone app to help make ethical decisions

Facing a moral dilemma New app can help! A new smartphone app can help you do the right thing when struggling with a moral quandary. The Ethical Decision Making app does not ask for the details of your problem or the options you are considering.It works by asking the user to consider each solution and rate it from five standpoints: utility, virtue, rights, justice and the common good. The user assigns a weighting to each of these factors. One could, for example, give justice more emphasis than therest. The app then scores the solution according to the customised moral framework the user have just set up, 'New Scientist' reported.

Smart cap that uses LED

can read your mind

Scientists have developed a new mind-reading cap that uses LEDs to record neural activity. Researchers advanced a brain-scanning technology that tracks what the brain is doing by shining dozens of tiny light-emitting diode lights on the head. This new generation of neuroimaging compares favourably to other approaches but avoids the radiation exposure and bulky magnets the others require, according to a research at Washington University School of Medicine in St Louis. The optical approach to brain scanning is ideally suited for children and for patients with electronic implants, such as pacemakers, cochlear implants and deep brain stimulators (used to treat Parkinson's disease). The new technology is called diffuse optical tomography (DOT).
