POPSGlasses don't make you a nerd Or geek - There's more to it... There was another article a few months ago that studied myopia amongst Asian students, due to rates that are seen as high. It was suggested there that myopia, rather than being inherited, was a result of lack of exposure to light. Students with myopia didn't tend to get out as much. Science can have have trouble qualifying things that are a result of more than one reason. experiments that support or prove theories, are better if only one thing can change. They are missing the point. The reason geeks, and nerds don't 'socialize', or 'get enough light' isn't because they are unsociable, but perhaps because they 'travel' in a different social circle, which is cyber, and global, through the internet. Perhaps they can develop terminal screens that emit the wavelengths of solar radiation so chronic computer users avoid developing myopia.

POPSFound! Biggest web of dark matter They should give it a better name They say we would no doubt find bigger examples if we could see further. Hubble is dying, and there seems to be no sign of a replacement, with the amount spent on the military While we could be learning about the universe, we have leaders leading us into trenches.

POPSKnee gadget fires up your mobile. They say it can power 10 mobile phones. I thought that thinking seemed fairly narrow, but batteries might be another story. Good for places where there is no electricity, and any number of battery powered devices are good for about an hour without A/C It doesn't look like the kind of thing you would use unless absolutely necessary, but it reminds me of the backpacks they used to describe as mobile phones.

POPSA touchy feely invisible cosmos The Universe in Braille. Sounds unlikely, but the point is made that the images we see that have been taken by the Hubble, Chandra X-Ray, and Spitzer infra Red Telescopes, are graphis representations of wavelengths outside the visible spectrum. There is no reason a blind person would have any less accurate picture of the Universe than a sighted person. Perhaps their view can be clearer, because they are not made blind by preconception.

POPSNanotubes yield the Blackest Black 30 times darker than the current Standard of Blackness set by the U.S. National Institute of Standards and Technology. The light that hits it is not reflected it is collected, but they have so far been working with visible light, and are continuing tests with other wavelengths. The creator Pulickel Ajayan, also holds the 2006 Guiness Book record for worlds smallest brush

POPSUV test helps fingerprint Blue Diamonds After exposure to UV light, the Hope Diamond, continues to glow after the light is turned off. When on display it cannot be seen in UV light, so they plan to make a video. Each diamond is composed of slightly different trace elements, so each diamond can have a spectrographic signature. UV can also help identify smaller diamonds that were once part of a larger stone.

POPSIs Time disappearing from the universe? At an everyday level, the change would not be perceptible. However, it would be obvious from cosmic scale measurements tracking the course of the universe over billions of years. The change would be infinitesimally slow from a human perspective, but in terms of the vast perspective of cosmology, the study of ancient light from suns that shone billions of years ago, it could easily be measured Difficult to fathom.

POPSSpitzer Space Telescope I saw a story where scientists thought they'd found out where cosmic dust came from. There were no pictures, so I followed the link to the telescope. There was much more to see, so I clipped the telescope. I think it's more of an infra red

POPSTardis 4 port USB hub and sonic screwdriver The sonic screwdriver is said to write in invisible ink, that can be seen with UV Light. I was going to get more RAM, but now my USB port is looking relatively old. I'm sure the postage will be cheap. (I wonder if the TARDIS, has a Carbon footprint.) The Daleks? They are remote control, but I'm sure Davros thought the same thing.

POPSBrave New World-Aldous Huxley (1894-1963) Aldous Huxleys vision of the Future, where a World State dictates that individuality be sacrificed for the sake of 'stability. The clip contains an introduction to the first chapter, with direct links to other chapters.

POPSVenus flytrap inspires snapping lens The lenses are like microscopic tennis balls, cut in half. With a little pressure the lens can change from concave to convex, giving a surface new properties, that can have many applications, from color changing paint, or road signs that can change with heat, or light, or on demand. Each depression, is about the size of a human hair

POPSRainbows give computers more oomph The plan is to use light to carry information rather than electrons. The light can be directed or controlled using materials smaller than the lights wavelength to assist in the processing, with different streams being carried by different wavelengths of light.
