Discussion Overview

The discussion revolves around the recent breeding of transgenic pigs in Taiwan that exhibit green fluorescence due to the incorporation of jellyfish DNA. Participants explore the implications of this genetic modification for research, as well as the characteristics of the pigs and their potential applications in stem cell research and human disease studies.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • Some participants highlight that the pigs are the only ones reported to be green throughout, including their internal organs, as opposed to previous partially fluorescent pigs.
  • There is a discussion about the nature of the fluorescence, with one participant clarifying that a specific light source is needed to activate the green fluorescent protein (GFP) in the pigs.
  • Another participant humorously suggests a potential name for the pigs, "GFPigs," based on their genetic modification.
  • Concerns are raised about the pigs being exposed to radiation, which are addressed by clarifying that the green color is due to genetic modification rather than radiation exposure.
  • One participant shares their experience with fluorescent organisms, indicating a broader interest in the topic of genetic modification and fluorescence in various species.

Areas of Agreement / Disagreement

Participants generally agree on the scientific basis of the pigs' fluorescence and the role of green fluorescent protein, but there is a mix of humor and skepticism regarding the implications and characteristics of the pigs.

Contextual Notes

The discussion does not resolve the broader implications of genetic modification in animals or the ethical considerations surrounding such research.

Just something interesting I came across on BBC News.

Scientists in Taiwan say they have bred three pigs that "glow in the dark".
They claim that while other researchers have bred partly fluorescent pigs, theirs are the only pigs in the world which are green through and through.
The pigs are transgenic, created by adding genetic material from jellyfish into a normal pig embryo.
The researchers hope the pigs will boost the island's stem cell research, as well as helping with the study of human disease.
The scientists, from National Taiwan University's Department of Animal Science and Technology, say that although the pigs glow, they are otherwise no different from any others.
Taiwan is not claiming a world first. Others have bred partially fluorescent pigs before; but the researchers insist the three pigs they have produced are better.
In daylight, their eyes and skin are green-tinged
They are the only ones that are green from the inside out. Even their heart and internal organs are green, the researchers say.
To create them, DNA from jellyfish was added to about 265 pig embryos which were implanted in eight different sows.

Finally, what the world had been waiting for! :-p
 
Were they expossed to raditon?
I wonder what green eggs and hame taste like

No, they have green fluorescent protein incorporated in their DNA.

Would they be called GFPigs then? Also they don't really "glow in the dark". A light source (488 nm) is required to activate the fluorophore that has been expressed in the tissues of the pig. Then the tissues will emit light at about 520 nm which is green in color. I've seen this done with mice and they are really fascinating to look at under fluorescing conditions.
 
I do that with worms everyday :-p
