Fantastic Voyage

Remote-controlled microbots may aid your doctor on your next visit

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.

Kind of like Fantastic Voyage, with robots.

Notes: Sailing the Hudson

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!

Women with the Right Stuff

Via the Daily Mail: In the early 60s, 13 women undertook secret tests at Nasa to see if they could become astronauts. Were it not for rules which prevented them from flying missions, the first woman in space could have been an American.

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.

Southern Comfort : Playing with actions in Photoshop

Photos taken at Savannah’s  Bonaventure Cemetery, which became famous when it was featured in the 1994 novel “Midnight in the Garden of Good and Evil”.

The Spanish moss and scenery were charming and spooky at the same time. But it was a sunny day, which didn’t add much to the atmosphere.

I desaturated the photos a bit, added some diffuse light, warmed the colors and recorded it as “Southern Comfort” in Photoshop Actions.

Although my version of photoshop is old (C4) I was thinking of posting it on Git Hub –
