MIT scientists have been working on an answer for a decades-old question of whether it is possible for a gas to show properties similar to a magnet made of iron or nickel. Ferromagnetic materials are those that, below a specific temperature, are strongly magnetized even in the absence of a magnetic field. In common magnets… »

Wireless power has been available for a century, ever since Nikola Tesla worked on its development. The genius’s Wardenclyffe Tower was to be an experiment in beaming electricity wirelessly across the world, eliminating the need for a wired power grid. Since then, wireless electricity has been developed mainly for usage at short distance and for… »

A new ultrasound device, used in conjunction with magnetic resonance imaging (MRI), allows neurosurgeons to precisely burn out small pieces of malfunctioning brain tissue without cutting the skin or opening the skull. A preliminary study from Switzerland involving nine patients with chronic pain shows that the technology can be used safely in treating humans. The… »

In one of our previous articles we started series about art and technology. We wrote about Theo Jansen and his Strandbeest. In this article we’re also going to write about kinetic sculptures, although animated in a completely different way. Human kind has ever since the ancient times used to make sculptures which cause admiration, and… »

A flying micro-robot has been developed by researchers at the University of Waterloo in Ontario. A research team, led by Professor Mir Behrad Khamesee, manipulates magnetic fields to levitate and move around three axes a robot weighing about three-hundredths of an ounce. The micro-robot discovery provides researchers with more control over the micro scale environment,… »
