争议终结:超大规模研究证明了转基因是安全的

2016-05-20 Cedric 煎蛋网

日前,一项为期两年的研究分析了过去30年近900篇关于转基因的期刊文章,最终得出结论:没有证据显示转基因农作物食用不安全,或者对环境有危害。但是也几乎没有证据支持转基可以显著提高作物产量或者改善农民收入,这说明我们远未找到使用和推广这项技术的最佳方法。这份厚达400页的报告由20名科学家完成,由美国国家科学院,国家工程院和国家医学院委托,以了解如何规范转基因作物和食品发展。无论你是吹是黑,你都无法

日前,一项为期两年的研究分析了过去30年近900篇关于转基因的期刊文章,最终得出结论:没有证据显示转基因农作物食用不安全,或者对环境有危害。

但是也几乎没有证据支持转基可以显著提高作物产量或者改善农民收入,这说明我们远未找到使用和推广这项技术的最佳方法。

这份厚达400页的报告由20名科学家完成,由美国国家科学院,国家工程院和国家医学院委托,以了解如何规范转基因作物和食品发展。

无论你是吹是黑,你都无法改变这个事实:从上世纪80年代开始,科学家们就在改造农作物的基因以增强它们的有利特征,比如维生素含量,产量或者抗虫性。



尽管有大量研究说明转基因作物是安全的,而且对人类有益,但是这并不能打消公众的顾虑。这也是这项分析被委托的原因之一。它调查了争论的不同方面,一共研究了超过900份文章,并且听取了专家作证和公众意见,最终得出以下的结论:

健康风险:

“委员会仔细调查了现有的所有研究以寻找消费转基因产品对健康直接不利的有说服力证据,但是没有找到任何证据。”

不仅于此,有证据显示转基因作物多人体健康有好处,因为降低了农药含量和提高了维生素含量。

对环境的影响:

“种植抗虫性或者抗杂草性作物没有降低农场的总体植物和昆虫多样性,有时抗虫性作物会增加昆虫多样性。”

最大的担忧之一就是修改过的基因会扩散到野生环境里——虽然有研究说明这可能会发生,但是报告结论说这股基因流并未产生任何负面效应。

对农民的冲击:

“委员会调查了美国开始推广转基因作物之前和之后的大豆、棉花和玉米的产量增长率,没有证据显示转基因作物改变了产量增长率。”

虽然一些转基因作物可以让农民获利更多,但是他们也需要额外的培训和基础设施,这些很昂贵,是要花钱的。

委员会在报告中说:“如果要可持续地推广转基因作物,我们需要更多的规范和激励措施,从而更完整和可持续的害虫管理方法在经济上可以承受。”

篇幅过长,没有阅读:

目前我们所有的证据都说明转基因作物对人类和环境手安全的,但是就帮助人类种植更多食物而言,并没有我们想象地这么好。



提到监管时,报告总结说,拜两个领域的新技术所赐,转基因作物和传统培育作物之间的界限正在变得模糊。在未来,我们需要想出不同的方法来分类和管理这两类作物。

佐治亚大学农作物与土壤科学教授Wayne Parrott没有参与委员会,他告诉the Genetic Expert News Service说:“读完这份报告,得出的一个不可避免的结论就是转基因作物也就是一般作物。它们不是支持者所宣称的灵丹妙药,也不是反对者眼里的可怕恶魔。”

虽然这份报告不太可能终结一切争论,但是它至少是基于证据的探讨,这也是我们前进的唯一方式。

曝首位“转基因人”或在两年后出现 将与病毒结合

美国一家医疗公司近日表示,到2017年,通过修改基因的方法,可以帮助治疗人类的眼部疾病。如果该预想实现,意味着两年内将出现人类历史上首位转基因人。 该公司名叫埃迪塔医药,致力于通过修改基因帮助病人治疗先天性黑朦。该公司首席执行官卡特琳·博斯利近日在美国麻省剑桥市参加会议时表示,有信心通过名叫“Crispr”的最新转基因技术,帮助患者治疗先天性黑朦。博斯利说:“感觉 有点快,但我

Nature:“涉嫌造假”,阐述转基因有害的文章被撤回

2016年1月21日 讯 /生物谷BIOON/--最近,几篇报道“动物食用经过遗传改造的庄稼后产生危害后果”的文章因数据造假正在接受检查。这篇由意大利Naples大学的科学家们报道的研究结果出现了漏洞:该文章中的的图片涉嫌故意修改。对此,该实验室的主要负责人称不会发表任何意见。 该文章的结果与之前由全球各地食品药品监督管理机构的安全测试结果(即表明转基因作物安全无危害)大相径庭。然而,这些官

FDA批准转基因鸡,用于生产罕见病药物

美国食品药品监督管理局(FDA)如今批准利用一种转基因鸡产下的蛋制造一种药物Kanuma 。 这种药物——名为Kanuma (sebelipase α)——是由亚力兄制药公司销售的一种重组人类酶。它能够取代人体中的一种错误的酶,这种酶与一种罕见的遗传病(人体无法分解细胞中的脂肪分子)有关。 经12月8日由FDA批准,Kanuma加入了美国市场的一小群“特殊药物”之中。

BMC Biotechnology:糖尿病福音,转基因蛆虫治疗足溃疡!

北卡罗来纳州大学的研究人员发现,转基因绿蝇(丝光绿蝇)幼虫可以产生和分泌人类生长因子,有助于促进细胞生长和伤口愈合。将无菌实验室养的绿蝇幼虫用于蛆虫清创治疗(MDT),主要是不愈合的伤口,尤其是糖尿病足溃疡,可以促进其愈合。使用蛆清洁创面,不仅可以去除坏死组织,还能够分泌抗微生物因子。这是符合成本效益的治疗,并且已经得到了食品和药物管理局(FDA)的批准。然而,关于MDT缩短创面愈合时间的随机临床

反转基因人士调查科学家与产业关系

孟山都公司与科学家的关系成为反转基因团体的调查目标。图片来源:Daniel Acker/Bloomberg/Getty 近日,对于转基因生物体反对者要求阅读自己的邮件,美国华盛顿州立大学营养学家Michelle McGuire感到十分震惊。 加州奥克兰“我们有权知道”依照《信息自由法案》申请阅读McGuire与约36个组织和公司的通信。McGuire是40位被该组织定为目标的研究人员之一

聚焦:转基因作物除草剂引争议

 似乎对于很多人(包括很多科学家)而言,转基因生物似乎和日常生活相隔很远,似乎也没有产生直接威胁。人们相对而言可能更担忧的是生物武器,比如那些可以造成大量死亡或者人体基因突变的生物武器。实际上,转基因生物,尤其是转基因植物离我们并不遥远。近些年来,在北美地区,有大量的转基因植物被种植,并进入市场,转基因作物(如玉米和大豆)已经非常普遍了。与其他很多国家不同,美国的食品药品监督管理局(
