Washington university scientists build tiny, self-driving robot powered only by light and radio waves
Small mobile robots carrying sensors could perform tasks like catching gas leaks or tracking warehouse inventory. But moving robots demands a lot of energy, and batteries, the typical power source, limit lifetime and raise environmental concerns. Researchers have explored various alternatives: affixing sensors to insects, keeping charging mats nearby, or powering the robots with lasers.…

Scientists research ‘matter waves’ to shine light on post electronics future
Most modern technologies owe their success to advances in electronics. These devices harness the flow of electrons in different ways to create computers, charge batteries, light-up displays, and move motors. Now researchers are starting to explore ways to harness the flow of waves of whole atoms, called matter waves, to enable new kinds of sensors,…

Swiss scientist developing robot that ‘grips without touching’
A scientist at the Swiss university ETH Zurich is developing a robot that “grips without touching”. The technology is based on sound waves, or “ultrasound waves”, to be more precise. ETH pioneer fellow Marcel Schuck is responsible for the invention, and has a small version of the robot on his desk.

Samsung moves into the vertical farming market
Agricultural innovations are essential for feeding our ever-growing global population. Especially these days, as industrialisation and global warming continue to negatively affect soil fertility and reduce the amount of arable land. According to the United Nations, the world’s population is set to reach 9.8 billion by 2050.
