>U.S. scientists have developed a strain of green-glowing cats with cells that resist infection from a virus that causes feline AIDS, a finding that may help prevent the disease in cats and advance AIDS research in people.
>The study, published Sunday in the journal Nature Methods, involved inserting monkey genes that block the virus into feline eggs, or oocytes, before they are fertilized.
>The scientists also inserted jellyfish genes that make the modified cells glow an eerie green color — making the altered genes easy to spot.
>Tests on cells taken from the cats show they are resistant to feline immunodeficiency virus, or FIV, which causes AIDS in cats.
>[...] So far, Poeschla's team has only tested cells taken from the animals and found they were resistant to FIV. But eventually they plan to expose the cats to the virus and see if they are protected.

This sounds more like troll science then the real thing. seriously, you just change a few genes and you can make an entire organism glow?

>>	Anonymous Tue Sep 13 21:58:59 2011 No.3734230 yes and not one gene is responsible for intelligence

>>	SAGEGOESINALLFIELDS Tue Sep 13 22:00:59 2011 No.3734242 Genes and shit are really easy to be honest. The protein it transcribes is all it does. The real trick is to find the relation between genes and the temporal associations.

Keep in mind that you just change a few genes in a chimpanzee and you get a human. Yes, bioluminescence can be achieved by changing just a few or even one gene. They've done the same thing to pigs and rabbits. Think about it, if you have one gene that expresses the luminescence, that's in the skin cells, and the whole organism is covered in skin... Kind of simple actually, not troll science.

Troll science would be more like:
>Crack glowstick to activate glowing
>Remove glowing fluid from inside with hypodermic syringe
>Inject cat with glow solution
>Enjoy your glowing cat!

This is very common practice in molecular biology when recombining genes. One protein is responsible for the ability to glow under UV light so SCIENTISTS usually insert it along with other genes they want to recombine to make sure the organism took in the genes correctly. This is very common practice in molecular biology.

Sure it's common... just don't be disappointed if you're mostly recombining DNA in bacteria.

Also, enjoy finding a job for shit pay despite your knowledge and expertise because the world doesn't appreciate this science enough to make it into a bigger industry.

I track my modifications with GFP errday. Think about the usefulness:

>insert green fluorescent protein in same regulatory sequence
>if promoter is allowing expression of GFP, your gene of interest is in there too

It makes keeping track of complex physiological changes so easy, you can just SEE it.

>>	Anonymous Wed Sep 14 02:23:59 2011 No.3735585 >>3734212 >seriously, you just change a few genes and you can make an entire organism glow? Yeah, actually, that's exactly how it works. It's been done numerous times before. It has even been commercialized, and done for an art show.

sort of. basically, jellyfish make this thing called green fluorescent protein. this shit glows under a black light. we know the sequence for this gene. "scientists inserted jellyfish genes that make the modified cells glow." this is a simple way of saying they took the necessary things to make the cells express GFP (gene sequence, transcription factors, etc), and basically made the gene always on, so any modified cells would constantly be making GFP and glow green

speaking of changing the colours of animals and stuff using SCIENCE, i've often wondered if its possible to have some sort of pill(or whatever) that does science and makes your hair or skin change colour, sounds like it would be an amazingly profitable thing to invent, if you could make your hair GROW a certain colour instead of dying it.
