1. 《異形》電影里的生物，有可能出現在現實中嗎
日本科學家研究發現，福島核事故之後，由於受到放射性物質的影響，日本的蝴蝶品種出現了翅膀變小、眼睛發育不規則等明顯的變異現象。2011年3月福島核事故後兩個月後，研究人員從日本10個不同地區採集了144隻成年酢漿灰蝶樣本進行研究。研究發現，核輻射越嚴重地區的蝴蝶，其翅膀和眼睛的變異現象越明顯。
據英國廣播公司8月13日報道，日本琉球大學的研究人員發現，爆發核危機的日本福島縣蝴蝶出現嚴重基因突變，他們發現很多蝴蝶的腿、觸須以及翅膀形狀發生變化。在實驗室試驗顯示，這些異變與放射性物質有關。
福島核危機爆發2個月後，琉球大學的研究人員就在日本10個地方，包括福島地區，收集了144隻成年草酢漿灰蝶。核危機發生時，這些成年蝴蝶應該處於正在過冬的幼蟲狀態。通過對比不同地區蝴蝶出現的基因突變，研究人員發現在有大量放射性物質的地區，蝴蝶翅膀更小，眼睛發育不規則。6個月後，研究人員再次從上述10個地方收集蝴蝶，發現來自福島的蝴蝶基因突變率幾乎是此前2倍。
研究人員得出結論稱，這些基因突變率更高的蝴蝶是吃了被污染的食物，此外上一代蝴蝶將已經發生突變的基因傳給後代，雖然這些特徵在前一代成年蝴蝶身上的表現並不明顯。
早在福島核危機爆發前，日本研究人員就用蝴蝶作為「環境指示物」，它們對環境變幻非常敏感。
專門研究切爾諾貝利核輻射對動植物影響的美國南加州大學生物學家蒂姆·穆蘇(TimMousseau)說：「日本的研究非常重要，這些基因突變和形態異常現象只能用暴露在放射污染環境下可以解釋。」

2. 日本核輻射變異人真實照片 對後代的影響到底多可怕
2011年發生的日本福島核電站相信大家都是知道的。這是世界上影響最大的核泄漏事件。這次事件造成的影響不僅僅只是財產損失，國際社會的恐慌，更多的是一系列的變異，不光是動物變異，植物變異，很多人也都受到了感染，日本核輻射變異人真實照片，對後代的影響到底多可怕？福島核泄漏後變異女人生出來的孩子也都是變異的，這絕對是可怕的悲劇。
日本核輻射變異人真實照片
當然這些還不是最讓人擔心的，最擔心的還是日本後期的處理。就在這件事過去了十幾年之後，也就是2021年4月13日，日本決定將福島第一核電站的核污染水排入大海。這樣的決定是極度不負責任的，不但污染了日本周邊，還讓全世界也跟著一起污染。這樣的做法也遭到了多國的反對，雖然這些廢水是處理過的，但是處理的是否合格還是不清楚，而且排入大海這也是對自然環境的破壞。一次核泄漏事件固然可怕，但是更可怕的是日本時隔多年後還是沒有做出一個很好的補救，這顯然是對人類世界的不尊重。

日本科學家研究發現，福島核事故之後，由於受到放射性物質的影響，日本的蝴蝶品種出現了翅膀變小、眼睛發育不規則等明顯的變異現象。2011年3月福島核事故後兩個月後，研究人員從日本10個不同地區採集了144隻成年酢漿灰蝶樣本進行研究。研究發現，核輻射越嚴重地區的蝴蝶，其翅膀和眼睛的變異現象越明顯。
研究組的一位研究人員表示，之前一直都認為昆蟲的抗輻射能力很強，因此該研究得出的結論有些出人意料。6個月之後，研究人員再次從上述10個地區採集蝴蝶樣本，結果發現福島地區的蝴蝶變異幾率變成了原來的兩倍。研究人員指出，變異幾率上升的原因一部分是因為攝入受輻射的食物，另一個原因就是基因遺傳。受到輻射初期沒有表現出變異症狀的蝴蝶，它們的下一代可能就會表現出明顯的變異症狀了。該研究結果表明，雖然福島地區的輻射殘留物質已經明顯減少，但對動物和環境的輻射影響仍然存在。 Exposure to radioactive material released into the environment has caused mutations in butterflies found in Japan, a study suggests.
Scientists found an increase in leg, antennae and wing shape mutations among butterflies collected following the 2011 Fukushima accident.
The link between the mutations and the radioactive material was shown by laboratory experiments, they report.
The work has been published in the journal Scientific Reports.
Two months after the Fukushima Daiichi nuclear power plant accident in March 2011, a team of Japanese researchers collected 144 alt pale grass blue (Zizeeria maha) butterflies from 10 locations in Japan, including the Fukushima area.
When the accident occurred, the alt butterflies would have been overwintering as larvae.
Unexpected results
By comparing mutations found on the butterflies collected from the different sites, the team found that areas with greater amounts of radiation in the environment were home to butterflies with much smaller wings and irregularly developed eyes.
"It has been believed that insects are very resistant to radiation," said lead researcher Joji Otaki from the University of the Ryukyus, Okinawa.
"In that sense, our results were unexpected," he told BBC News.
The Japanese researchers have been studying the species for more than a decade Prof Otaki's team then bred these butterflies within labs 1,750km (1,090 miles) away from the accident, where artificial radiation could hardly be detected.
It was by breeding these butterflies that they began noticing a suite of abnormalities that hadn't been seen in the previous generation - that collected from Fukushima - such as malformed antennae, which the insects use to explore their environment and seek out mates.
Six months later, they again collected alts from the 10 sites and found that butterflies from the Fukushima area showed a mutation rate more than double that of those found sooner after the accident.
The team concluded that this higher rate of mutation came from eating contaminated food, but also from mutations of the parents' genetic material that was passed on to the next generation, even though these mutations were not evident in the previous generations' alt butterflies.
The team of researchers have been studying that particular species butterfly for more than 10 years.
They were considering using the species as an "environmental indicator" before the Fukushima accident, as previous work had shown it is very sensitive to environmental changes.
"We had reported the real-time field evolution of colour patterns of this butterfly in response to global warming before, and [because] this butterfly is found in artificial environments - such as gardens and public parks - this butterfly can monitor human environments," Prof Otaki said.
But the findings from their new research show that the radionuclides released from the accident were still affecting the development of the animals, even after the resial radiation in the environment had decayed.
"This study is important and overwhelming in its implications for both the human and biological communities living in Fukushima," explained University of South Carolina biologist Tim Mousseau, who studies the impacts of radiation on animals and plants in Chernobyl and Fukushima, but was not involved in this research.
"These observations of mutations and morphological abnormalities can only be explained as having resulted from exposure to radioactive contaminants," Dr Mousseau told BBC News.
The findings from the Japanese team are consistent with previous studies that have indicated birds and butterflies are important tools to investigate the long-term impacts of radioactive contaminants in the environment.
