This poor Brian fellow got issues ... beginning with the fact that he don't even know the gender of his own noggin. No wonder he's a quirky dyslexic!

Some fun home experiments to try while reading the tongue twisters piece:

1. Do you get similar garbling from imagining saying the phrase as from repeating the phrase aloud?

2. Does it matter if you re-read a given phrase as you speak it, as opposed to reciting it from memory?

[URL="http://medicalxpress.com/news/2013-12-cells-eye-inkjet.html"]Cells from the eye are inkjet printed for the first time[/URL][QUOTE]At the moment the results are preliminary and provide proof-of-principle that an inkjet printer can be used to print two types of cells from the retina of adult rats―ganglion cells and glial cells. This is the first time the technology has been used successfully to print mature central nervous system cells and the results showed that printed cells remained healthy and retained their ability to survive and grow in culture.[/QUOTE][QUOTE]The cells derived from the retina of the rats were retinal ganglion cells, which transmit information from the eye to certain parts of the brain, and glial cells, which provide support and protection for neurons.
"We plan to extend this study to print other cells of the retina and to investigate if light-sensitive photoreceptors can be successfully printed using inkjet technology. In addition, we would like to further develop our printing process to be suitable for commercial, multi-nozzle print heads," Professor Martin concluded.[/QUOTE]

I first imagined "printing" each cell by spewing individual portions, such as nucleus, mitichondria and membrane. But no, it's not at that level!

It spews whole cells, in a liquid medium, onto some structure/backing suitable for growing artificial tissue grafts.

Here is a process that aims to wipe out the cells of a donor heart (leaving a spooky, gross, night of the living dead looking scaffolding) and then will then grow the recipient's heart cells on what remains:

And it looks like they are pretty far along on printing kidneys:

This is the emerging technology to watch, I think.
