Glow-in-the-Dark Cats

December 12, 2007 1:55 PM

Glow_cats_071212_main Please click on the picture to the left and bask in its warm (or cool) glow while you read the rest. 

We're not entirely sure what to make of this story, but a team in South Korea says it has cloned two cats--who happen to glow red when exposed to ultraviolet light.

Just why would you want a cat that glows in the dark?  It was just an interesting accident, says the lead researcher, Kong Il-keun of Gyeongsang National University, as quoted by the South Korean Ministry of Science and Technology.  They were only interested in getting cats with something called red flourescence protein, useful if you want to track genetic activity in the animals. 

From Korea.net: "'The ability to manipulate the fluorescent protein and use this to clone cats, opens new horizons for artificially creating animals with human illnesses linked to genetic causes,' a government official said. This, he said, can speed up efforts to find treatment and drugs by allowing scientists to study animals and conduct experiments that are not possible with human patients."

That or you're trying to get a really odd picture.

This is not new. Several years ago, scientists did this with other animals, only on purpose.

One example was the GloFish

Whoa!!!! Too cool! I want a cat that glows in the dark!!

"an interesting accident" said the lead researcher.How many, not so obvious "interesting accidents" have been released to the wild by the bio-tech industry.

Glowing animals. Well now the Republicans can hunt in the dark too.

This shows why cloning needs to be regulated. Although the South Korean doctor gave a very lucid explanation of why these cats were created - to track illnesses that affect humans - it demonstrates one of the dangers of cloning. Some vapid American consumer is going to want to buy a glow-in-the-dark cat. Without regulations and standards, cloning becomes "weird science" instead of scientific progress. People can be so unbelieveably selfish that they end up destroying themselves. It is sad.

It's great to see that great strides are finally being taken in the field of Mad Science.

Now if only they could get the Death Ray, Weather Machine, Flying Car, and 50 Foot Badger projects on track.

Why do we do these things? Experiments sure.. but needed? No so sure.

Posted by: Molly | Dec 12, 2007 3:34:08 PM

WHY DID THAY RILY DO IT?!?!?!??!?!*&^%$#@

Posted by: payton | Dec 12, 2007 3:47:52 PM

If you read the last paragraph, you will see that the goal is to clone animals w/ GENETIC DISEASES to test them to find treatments. They would do this with animals because the experiments they would conduct wouldn't be allowed for humans. Its NOT MORALLY or CONCEIVABLE to conduct upcoming experiments on humans - but ANIMALS HAVE NO SAY. How WRONG is it for them to PLAY WITH INNOCENT ANIMALS LIVES BY TESTING THEM WITH HUMAN DISEASES???

Several years ago my mother was dying her hair black and our white cat was bugging her, so my mom drew a line down the white cats head. When the cat gave a litter, all the kittens had a black mark as well!

Posted by: AC | Dec 12, 2007 4:08:44 PM

The morality of experimenting on animals is drawn from a poor logic that the ends justify the means. People are so stupid.

Posted by: hatey | Dec 12, 2007 4:26:38 PM

The use of animals in scientific experiments should not be allowed or tolerated.

I think this is viral...Thik about it its christmas time!

Just moving us one step closer to a Glow in the Dark Godzilla and Monthra taking over the world...

Posted by: Christopher | Dec 12, 2007 6:19:32 PM

That fearless mouse made in Japan is so stupid. We all know the possibilities for the future of such a mouse. There is a difference between brave and stupid. The same goes for glow in the dark cats. That is just as stupid. When are scientists going to take responsibility and do some real and meaningful research? Their funding should be pulled for doing harm to nature. Just because something is possible doesn't mean that it should be done. Shocking is not the goal that we are looking for. With so many people in need, these are not things that we should be doing. Research the usefulness of plants.

they weren't trying to make them glow in the dark...that was just a mistake

Posted by: lostsince1988 | Dec 12, 2007 7:34:35 PM

Now I wonder how many accidents have they made to these poor animals? Come on this is animal abuse here.

Posted by: bhsztl90 | Dec 12, 2007 8:10:38 PM

This grotesque "science" experiment is immoral. They will produce hundreds of malformed animals while they end up with one or two that live, usually a short sickly life. Cloning animals is big businesses way of taking over the production of animals by creating a special type that only they own and can produce, which is sterile so you can't breed your own. Big business is already doing this with seed that they sell. It is genetically modified (corn, soy etc) and cannot reproduce, so you have to buy the seed every year to plant your crop. This eventually will make us fully dependant on the likes of Dupont etc. Protest!!!!

Posted by: SDenault | Dec 12, 2007 8:28:17 PM

They're just animals. The chicken, beef you eat are also animals. There is nothing immoral about it. That's the purpose of their existence

Posted by: K | Dec 12, 2007 9:59:39 PM

I believe these people have ALL THE RIGHT IN THE WORLD TO DO WHAT EVER THEY FEEL LIKE DOING,and you may ask why. Maybe its because they aren't even a part of our country. what are you animal loving gonna do next persecute the native people, of some random island, because they kill animals so they can live. People open your eyes we have used animals for many of our dirty tasks in our world history, and guess what it is never gonna change so live with it!

I am suprised at people. Somebody is actually taking the steps to see where we really are and where we are going, scientifically. My three explanations as to why somebody would be angry about them doing this. 1. Your scared or 2. your religious (no insult intended). Or 3. You believe the sci-fi movies that are dramatizations (not real). I agree it should be regulated, however they are not cloning these cats to kill them. Just to see what kind of genetic changes are going on. It's why they used the UV, so they could track them.

This form of bazaar experimental outcome causes an anxiety of uncertainty within me. We are now apparently as a civilization able to breed animals with human deseases genetically introduced into the animals DNA. Since in theory, human beings can also be cloned and genetically engineered, a real concern I have is the possibility of producing interspecies hybrids, perhaps even hybrids between humans and animals. If such is ever done, say between a non-human primate and a human, and the resultant being somehow out performs humans on at least a certain limited set of cognitive tasks, how will we treat this new form of highly sentient being. Would, for instance, the Catholic Church allow for its reception of the Catholic Sacraments? Would Evangelical Christians submit to the concept that the new creature can or cannot be Born Again? Would the U.S. government allow the creature to serve in the armed forces and perhaps become a Commissioned Officer or a U.S. citizen? There is some real danger here that I do not think our civilization currently has the ability to handle appropriately. Any government cover up of space alien technology and related events as destabilizing would seem foolish in light of the much more serious problems of producing smart or dumb human animal hybrids. And what about the possible terrorists future capability of eventually causing a normal adult human to genetically based morph into a monster or a chimpanzee or a dog. The possibility of learning how to rewrite genetic code or reprogram cells might one day allow such through nanotechnology. This is a real danger! We had better be very careful.

I think this is really neat. It doesn't seem like it actually glows in complete darkness, though; that's what i want. i'm a cat lover, and that would be awesome. i also like giraffes, and would like to see a genetically modified one that has been genetically miniaturized and is only 2 feet tall. i would let it run around in my fenced in back yard with the miniaturized elephants!

Posted by: steve | Dec 13, 2007 6:33:51 AM

Because we want one is not justification for having one. I like all animals and that is not justification for having them all in my house. Having everything that we want when we want it is losing touch with reality. No apparent harm is done other than the fact that we will find ourselves living in a world of make-believe. That means that we will miss out on things that are more important.

this is sooo kewl

hmmmm... why is it unethical to do this with humans... great way to track criminals on the run...

Well cloned glow in the dark cats sound interesting, but what are the guys going to do with them now? They did not intended for the animals to glow in the dark, they were doing something about red flourecent or something. I feel sorry for these poor animals. I know that animals are used for experiments, but I still like it. You know I think prisoners would make good experiment fodder. especially those sitting on death row. They could be of use to science. Sorry if I offend anyone.

THis is so CRAZY!!!
Look at them......... they have NO SOULS! look at those hollow eyes of nothingness! COULD U imagine waking up with that "KITTY" staring at you....

I am curious as to how they measure against cats bred in normal processes. Are they of equal intellegence? From watching the press videos on them, I can see that at least one of them has an unevenly formed features such as the muzzle and mouth area. They seem like possibly they're a little frumpy. These traits remind me of cats that have a very small gene pool because they are too closely bred with their own gene pool. (like british royalty, ha-ha). I would very much like to see these cats up close, but I will settle for reading the published articals on these koren cats with bioluminesence. I wonder which scientific journals will be publishing the works in english..

Posted by: Kathryn | Dec 15, 2007 5:20:27 PM

I think the cats are adorable. I want one!

On a more serious note, why are people questioning the scientist’s motives? The reasons were stated quite directly in the article. I imagine there are more reasons than the ones stated, but that is typical in science. It is quite common for research to be useful across a variety of fields.

Even if there were no clear reason for the research, why would it matter? Sometimes science is for the sake of science. There does not have to be a reason for everything. Sometimes we just want to know what is possible. If it isn't inhumane or excessively dangerous then I don't see the problem.

Posted by: Seavee | Dec 15, 2007 6:20:54 PM

To Hell with you bleeding heart libs.....I WANT ONE!!!

Posted by: Griz | Dec 16, 2007 2:21:18 PM

I want a glow in the dark cat. How cool is that?

Posted by: tim | Dec 19, 2007 10:43:38 AM

I think that it would be awesome to have a glow in the dark cat as long as the fluorescence protein won't hurt the cat in anyway.
