A confetti-sized artificial kidney stone, with a sub-150-micrometer hole bored into it using the focused sound beam

First of all, how can non-invasive surgery even be possible? After all, even in the case of minimally-invasive laparoscopic surgery, small incisions are still made in the skin. Nonetheless, that’s just what scientists from the University of Michigan are proposing. They believe that it could be achieved by using a beam of sound, which would be emitted through the skin to a highly-focused point within the body – and they’ve already created such a beam…

The ELF is a pedal/electric velomobile, that can be charged using a built-in photovoltaic panel

While it’s all very well and good to use an electric vehicle as your around-town ride, full-size electric cars can still be pretty pricey. Also, as many of their critics are quick to point out, the electricity used to charge their batteries currently still tends to come from eco-unfriendly sources such as coal-burning power plants.

The researchers say that WiFox software can improve data throughput by up to 700 percent and could be packaged as an update to existing networks. Current Wi-Fi hotspots can get annoyingly slow because both users and the Wi-Fi access point are connected via single channel that sends data back and forth, creating a bottleneck when a…
