Ultrashort-Pulse Laser Could Solve Dilemma of Nuclear Waste Disposal.... Researchers in Lithuania have developed an ultrashort-pulse laser that could eradicate nuclear waste and decrease the decay period from tens of thousands of years to seconds, hours, or months, depending on the material, they said.

Supersharp Images from New VLT Adaptive Optics


ESO’s Very Large Telescope (VLT) has achieved first light with a new adaptive optics mode called laser tomography — and has captured remarkably sharp test images of the planet Neptune, star clusters…

I hadn't actually thought of it this way... but I have to admit... I like the review. I think this might just be why I liked the movie so much.
I've always been a big Ridley Scott fan... and I certainly thought this film was a fitting tribute to one of my favorite movies of all time. ;)

In the example above I see a deep blue.


As a child I was inspired to experiment with this phenomenon by an item in a TV show (I don't remember which show - it may have been Blue Peter or possibly Tomorrow's World). In the days of black and white only television it was bizarre and astonishing to apparently see colours appearing on the screen and I recall the presenter speculating about the possibility of utilising the effect to produce actual colour images. As far as I am aware that line of enquiry was never pursued but, of course, as we now know the specific tints observed are highly subjective and so such a system, were it to be possible, would require a degree of personal tuning and would have ultimately failed for the same reason that 3D TV has repeatedly failed - i.e. it only works for one viewer at a time.
The original pattern used on the TV show, as far as I recall, was a disc of half black, half white with three roughly evenly spaced arcs each of perhaps about 60 to 90 degrees in length, one end of each was in contact with the black area. This... Show more...
