Gene gun
Look at this.
Looks easy, doesn't it? You basically take a ''nail'', cover it with
tugsten particles and genes, and fire it at an onion.
The possibilities are endless, I guess: glow-in-the-dark cats,
potatoes with tomato flavor, your private zombie army...
I hope this isn't too complicated!

Is the accompanying text to the (rather old looking) picture. Anybody else smell something fishy?
One shouldn't accept or resort to the mutilation of science to appease the mentally impaired.

Sorry man - you cannot do this.
The nail would likely contain contamination with bacteria, as well as the other things. Eliminating this would be hell. Research gene guns utilize
ultra-fine nano-scale particles: rather hard to obtain.
The nail's size would crush any cell.

They only seldom use nails. The carriers are about one micrometer in diameter and not that hard to obtain.
As for the swimmer, I've heard he's in advertising for swimming gear now.

In the UK you have to have a fire arms license to use a gene gun! I know I thought my lecturer was pulling my leg until he had a photocopy of his
license in his lecture handout!
They use high pressure helium to propell spherical gold (or other unreactive metal) particles coated in desired DNA into cellular targets.
I do not see why a "Mad Scientist" couldn't repeat such experiments at home! The selection of cells encorporating the DNA (and the correct DNA for
that matter) could be harder, depends what the DNA encodes and how easily it is selectable.

Question:
How are you going to get that plasmid?
These are highly engineered DNA sequences, with lots of insider know-how...no way that can be done at home 
Still I'm impressed about that swimmer - but not entirely convinced at all - if I understand it correctly, it'd have to be applied to all the desired
skin areas? Almost like a tatoo?
Not only that, I'd be surprised if the gene is so identical in chicken that it works in humans - in addition it'd have to differentiate terminally
differentiated cells (such as those of the skin, basically all cell types in an adult) with a developmental program humans do not have...
Hmmm...

A few months ago I saw some gold spherical nanopowder intended for this purpose up for auction on eBay--I regret not buying it.

By the way, that article is a SPOOF!!! (the one from sleep, http://www.nature.com/cdd/journal/v12/n4/full/4401614a.html)
Very surprising, given it's from a well reputed nature journal - but it was published in April (erm fools), from well-reputed scientists.
It is beyond me why they (they are clearly editors, or in good relation to them) thought this is appropriate - as it fools the layman - and even the
professional without a closer look.
Here is why it is a joke :
-p53 has no other homologues than p63 and p73.
-They call the protein WSD, for Wai So Dim - Why so Dim? 
-from 'Istituto Dermopatico dell' Immacolata Concezione' - institute of the immaculate conception? LOL

Wtf - stimuli are incompatible with LIFE? radical damage? Garble garble

| Quote: | | that controls the expression of the ER protein Scrotin |
The protein is called scotin, not scrotin, and has no relation to the scrotum...
| Quote: | | Based on new, patented biological effects of WSD we found two biotech companies, Gene-Italia (Italy) dedicated to the development of interdigital web
gene therapy and Ai-Bang-Mai-Ni (Japan) for orthopedic applications. |
We founded, not 'found' ... and the japanese company involved in orthopedic applications is called I-bang-my-knee?

So this champion is called 'Oh my god I swim fast'? The photo is by LSD? Truly indeed!!!
I guess the editors of that journal must have been tripping, or at least boozed up to the eyebrow to come up with this, and to get it published!
PS there are many more things that don't fly, mostly technical/scientific...but these are the obvious ones...

I suppose because p53 is so famous, that any new homologue would spur countless of subsequent studies (lots of them crap undoubtedly, as it is common
in such an important field) , and would merit seperate (not passing) attention as done in that article... but I agree I prob. should take that point
out, there are many other, garbly aspects in that article.

That explains it, I don't know anything about p53, I am ignorant of many things.

I think this is going off-topic.
Let's get back to the gene gun: Do you think it could be done at home?
Nail gun, projectile and onion should be no problem; the carrier is apparently sometimes sold on ebay,
but where would one get the marker gene?
I'm not going to try this in the near future; still, I'd like to know how it would be done.

Order a GFP expression plasmid (eukaryotic), coat it onto tiny tungsten particles and shoot this into an onion- it might start to glow there...

I do have a vial of 1 g of 25 nm TiO2 if anyone wants that....... It is excellent for absorbing anthocyanin pigments (which in turn sensitize and
release an electron -- a dye sensitized cell). According to the O Chem department (who are currently working with this), the anthocyanin bonds via
the OH groups). Maybe the sugars can bond on?
