LONDON: To better treat a variety of diseases, researchers have developed soft, flexible and motor-less micro-robots that can be remotely controlled with electromagnetic fields.
Made up of a biocompatible hydrogel and magnetic nanoparticles, these microbots can move and swim inside the patient’s body when an electromagnetic field is applied, accoding to the researchers from Ecole Polytechnique Federale De Lausanne, Switzerland who developed bio-inspired robots that looks and moves like a bacterium.
My daughter and I took an ‘intro to sailing’ course at Hudson River Community Sailing. I spent most of the time trying not to fall off the boat, and she mastered tacking and jibing. It was a great day!
Seven members of the Mercury 13 are pictured in front of the space shuttle in 1995. From L to R: Gene Nora Jessen, Wally Funk, Jerrie Cobb, Jerrie Truhill, Sarah Rutley, Myrtle Cagle and Bernice Steadman
Funk was America’s first female Federal Aviation Administration inspector and it was her skills as a pilot that, in 1961, led her to become one of 13 women who passed secret medical tests to become an astronaut.
The Mercury 13, as they are now known, undertook the same tough mental and physical tests as the famous silver-suited Mercury 7.
Those latter all-American heroes included John Glenn and played an important part in the space race against the Soviet Union, eventually placing a man on the Moon.
The Mercury 7 tests, memorably detailed in Tom Wolfe’s book The Right Stuff (later a film), pushed the men to their physical limits. The doctor who devised them, William Randolph Lovelace, was also head of Nasa’s Special Committee on Bioastronautics.

In a big leap for the electrification of aviation, an Extra Aircraft aerobatic plane performed its first public flight with an electric powertrain. The video shows the flight of the aerobatic aircraft with an electric propulsion motor from Siemens that weighs 50kg and produces 260kW.
