Normally, Magnetic Resonance Imaging (MRI) is interesting only the physicists for its uses in scientific research and the physicians for the fabulous pictures it gives of the insides of the human body.

An MRI scanner will allow to display fine cuts of the body of the patient laid into the machine, but what is to be seen when the human guinea pig is replaced with fruits or vegetables? We discover the new face of these friends of our everyday food. And when the pictures are animated, this gives something like:

I hope they will sell the poster somewhere.

If you’re not a scientist and you don’t understand these, there is no shame to feel. Some scientists are just wondering what this is all about…

The tracks are made of traditional magnets and the train contain a big super-conducting magnet (cooled down by liquid nitrogen to maintain its super-conducting characteristics). Everything is relying heavily on magnetic fields. So, not surprisingly, these fields can be observed in the real train. The following video — shot on the Rokko Liner in Kobe, Japan — shows metal paper clips dancing on the stray magnetic fields of such a Maglev train, going through the floor of one of the passenger cars.

Don’t drop your credit card (or an age-old floppy disk) on the floor for fear of seeing it quickly erased.

On the image on the left, Leonardo Da Vinci’s Mona Lisa has been converted to black and white (A), using color data and textures from a similar image (B), the algorithm built a color image again (C) not too far from the original (D).

Analyzing this work, I’d say that part of the differences between the result (C) and the original (D) come from the quality of the conversion to Black & White which led to an image quite hard (a bit more contrast than needed).

Impressive result on photos, you can expect to see it applied to moving images (and movies).
