Hackers could have used a vulnerability in electric scooters to cause road traffic collisions, researchers have revealed. They found a number of "critical" security flaws in a popular type of self-balancing electric scooter – also widely known as a'hoverboard' – that could let criminals remotely take control of one, even if it was being driven at the time. If they wanted to, they could throw the rider off by making it come to an abrupt stop, or even drive it into traffic. The I.F.O. is fuelled by eight electric engines, which is able to push the flying object to an estimated top speed of about 120mph.

US Navy officers are currently testing the world's first drone-killing laser capable of blasting targets with 30kW of power. The $40 million (£30 million) super laser moves at the speed of light and is'more precise than a bullet', according to naval officers. Live-tests of the new super laser have now begun in the Persian Gulf, and officials have predicted that it will be used in combat by 2020. While laser weapons have been a staple in science fiction films for decades, the US military is inching closer to making these a reality.

Robotic speedboats and drones have taken up life-guarding duty in a lake in China. Self-driving vehicles that can detect'moving targets' have started patrolling Tian'e Lake in Hefei, eastern China - an area where 15 people drowned in 2016. New images reveal how the autonomous boats are equipped with cameras, GPS and infrared and acoustic sensors, according to Chinese police officers.

A Japanese robot has begun probing the radioactive water at Fukushima's nuclear reactor. The marine robot, nicknamed the'little sunfish', is on a mission to study structural damage and find fuel inside the three reactors of the devastated plant. Experts said remote-controlled bots are key to finding fuel at the dangerous site, which has likely melted and been submerged by highly radioactive water. A Japanese robot has begun probing the radioactive water at Fukushima's nuclear reactor. An underwater robot has captured images and other data inside Japan's crippled Fukushima nuclear plant on its first day of work.
