Teacher of Agricultural University: A Fake News
In order to verify the authenticity of this post, the reporter made a special trip to the Horticulture College of Fujian Agriculture and Forestry University with the printed version downloaded from the Internet. He Laoshi, from the Vegetable Department of Horticulture College, read this post and shook his head: "It is reasonable to say that watermelon, an agricultural product, is researched and cultivated by the Vegetable Department, but this blue watermelon has never been cultivated in our department, and there is no DNA laboratory in our department. This is the first time I have heard of such a thing. In addition, if blue watermelon is really cultivated, the seeds of this watermelon have genes to control blue, and blue watermelon can be used to breed the next generation. In addition, the person who released this news said that it is not credible to teach part-time at Agricultural University, because people who can work part-time at Agricultural University are generally experts, and ordinary people can't teach part-time at Agricultural University. It must be false news. "
The reporter interviewed the teacher of fruit tree department and several students of crop science college who are doing experiments in the experimental field on the planting of blue watermelon in Agricultural University. It is said that the post is purely fake news and is a prank of some people.
It turned out to be PhotoShop production, and netizens pointed out that the flaw was obvious.
Xiao Xu, a computer student at Fuzhou University, saw this "fake news" on the Internet. He said that he knew at a glance that the picture of the blue watermelon was obviously PS. When making this picture on the computer, you only need to take a cut watermelon picture with a digital camera in advance, input it into the computer, and change the color of the watermelon through PHOTO-SHOP. "Don't say blue, it's easy to do five colors."
Another netizen directly pointed out the flaw of blue watermelon. He said that because the original picture was a red watermelon, it left a red reflection on the metal utensils in the kitchen. In the subsequent PS production process, the producer just changed the red pulp of watermelon into the blue pulp and pasted it. But he didn't expect the red reflection of the stove, metal kettle and metal shovel on the left in the image to reveal false clues. The more critical flaw is that on the green skin of the big watermelon next to the white bowl, there is a reddish reflection of a small piece of leftover watermelon below, which is obviously made without the smooth and natural color transition on the watermelon skin.
Of course, the most obvious mistake is that Fujian Agriculture and Forestry University was written as Fuzhou Agriculture and Forestry University by the producer and publisher.
Transgenic watermelon with blue flesh can be cultivated completely, but it has no market value.
Professor Wang Wencheng, who has been engaged in the research of animal and plant genes in Minbei Vocational and Technical College, believes that although the appearance of blue watermelon has not been officially reported, from a scientific point of view, it is entirely possible to transform the traditional red watermelon into blue watermelon. In the process of cultivation, as long as the genes controlling blue, green and purple in other similar plants are transferred into red and yellow pulp watermelons, it is possible to obtain blue, green and purple transgenic watermelons different from traditional red pulp through combined cultivation. In fact, colored peppers, color-changing carnations and blue enchantress roses that have been cultivated and listed at present are all masterpieces of genetic modification.
However, Mr. He of Agricultural University thinks that this is not feasible from a practical point of view. Cultivating traditional red and yellow watermelons into blue watermelons has high cost and no economic value, so it is of little significance to cultivate this blue watermelon.
Internet food rumors
Need reasonable doubt
There are many rumors about food, such as mouth-to-mouth drinking mineral water is not safe, drinking yogurt will detoxify food poisoning, high sulfur dioxide content in candied fruit will cause asthma, and pork neck meat will destroy people's immune system. What's more, it's about coke. For example, adding monosodium glutamate or beer to cola will produce stimulants and even produce sedative and hypnotic drug FM2. Coke+barbecue = bone cancer. These rumors are quite sensational and convincing.
Chen, director of the Food Hygiene Department of the Health Department of Taiwan Province Province, pointed out that online rumors are characterized by simplicity and grandstanding, and food-related online rumors can be roughly divided into two categories. One is to present it in the tone of experts and scholars, or to fabricate serious personal experiences, plus some specious theoretical basic organizations. With a little verification, it is not difficult to find that most of them are out of thin air. Another online food rumor is aimed at a specific brand, spreading the words "drinks sold by chain stores will kill people", which is not only out of goodwill, but even malicious slander. In fact, some rumors have a long history and have returned with the transformation of the Internet. For example, "Sausage+Yakult = Cancer" which has been circulating in Taiwan Province Province for more than 20 years has become "Bacon Sandwich+Yogurt Can Cause Cancer" on the Internet. Both of them are inferred from the same hypothesis and are not supported by medical evidence.
In Taiwan Province Province, in order to prevent people from being misled, the Health Department specially invited people to collect and sort out food network rumors, and then published them on the official website in a question-and-answer way to solve people's doubts.
In Chinese mainland, there are also many online food rumors, and online fake news is even more terrible. If the publisher of fake news is for fun, that's all. What is terrible is that some people use people's curiosity to achieve commercial speculation's goals, and even maliciously slander them, which is too much.
Internet provides technical support for the spread of rumors, but people's credulity and difficulty in monitoring objectively contribute to the spread of rumors. I hereby appeal to the public to improve their honest personality, cultural education and the spirit of seeking truth from facts. We should maintain a "reasonable suspicion" attitude towards the rumors on the Internet, confirm them in advance, or let the rumors stop at the wise and stop forwarding. Those who are difficult to distinguish between true and false can provide relevant information to relevant departments from authoritative channels for verification.
