Delegate this task to experts of the respective field.Common sense.
There are way too many conspiracy theory here.

和问题在哪里？
当然你要能证明转基因食品对人体没有任何影响，那更好了。
我还觉得organic的东西太贵 |

发帖数: 772 | 18 It wouldn't be fair to ask to "证明转基因食品对人体没有任何影响". For one thing, it is difficult to prove something doesn't exist, vs. to prove something that exists. For instance, is it fair to ask those atheists to prove that God doesn't exist, or should ask believers to prove that God does exist?
Secondly, it is not true that non-GM food 对人体没有任何影响 either. |

发帖数: 3662 | 19 研究转基因的scientists 只是这个环节的一部分吧，他们的课
题不会也不应该预设结论说非要支持还是反对。
另外反过来问同样的问题，学术界支持转基因无害的的科学家
多不多？
况且，有害无害更属于没有定论。我看应该有医学界介入，还要
有几十年的追踪调查。至少organic的我们吃了几千年都验证过
了，应该属于没问题了。。。

认知的范围内基本可以接受的影响。你拿上帝来说不可
知论比喻，那你岂不是否定科学讨论本身了。这个课题
本身当然是可知的，认识的程度多少而已。

发帖数: 772 | 21 I am not talking about 不可知论 at all. 不可知论 is agnosticism, but the example I used is atheism. These are two different things. Agnostics believe that the existence of God is non-knowable (and they wouldn't care about proving since it is non-knowable), while the atheists believe that God doesn't exist.

Actually, those support the transgene food exactly know the negative effect
on human body. However, they just don't want to tell Chinese because they
don't want to see Chinese in the future. |

发帖数: 3812 | 24 You are essentially calling for academic authoritarianism, a form of ad

I have seen lots of "biologists" who apparently lack the essential training
of logic, and it makes me wonder if that's due to the nature of its calling
or else.How does this impression sound to you? |

发帖数: 10787 | 38 这是靠生物理论指导，取得的成果吗？
正常的学科，都是先有正确理论，才能指导取得成功。
生物就是一个现代炼丹术，自己都不知道什么理论是正确的，就靠胡乱瞎蒙。还好意思
说这个理论正确，这个不正确。 |

发帖数: 26 | 42 In my knowledge, RNA are not stable, they are easily been digested by Rnase,
which is everywhere. That's why people work with RNA need to be very
careful to avoid RNA been chewed up. Also, RNA are not chemically stable.
The extrem acidic environment of stomach will destroy RNA.

You mean biologically active as before cooking?
Most are altered or denatured structurally and inactive.
But there are exceptions, e.g. remain active as toxins. |

Not paranoid, just rational and objective.
There are very few absolutes in science.
Most issues are ones of detectability.
Undetectable != Absent/Non-existent. |
