China is going to launch a satellite to help develop super space-enhanced fruit, vegetables and other crops, as it tries to find ways to increase the nation’s food production.
A satellite full of seeds will be launched on a rocket in early September for a two-week mission that will expose 2,000 seeds to radiation from space. The satellite will then fall back to earth and scientists will get the seeds back.
The “seed satellite” will let scientists try to grow high-yield and high-quality plants, said Sun Laiyan, head of the China National Space Administration.

“Exposed to (a) special environment, such as space radiation and micro-gravity, some seeds will change to such an extent that they may produce much higher yields and improved quality,” Sun said. Nine different kinds of seeds will be in the satellite.
China has been experimenting with exposing seeds to space for years. In the past, rice and wheat seeds that had been exposed to space grew more rice. Tomato and green pepper seeds that have been exposed to space have grown between 10 and 20 percent more vegetables than regular seeds. Vegetables grown from space-exposed seeds also have more vitamins.
However, the satellite to be launched in September will be the first used specifically for seeds. China’s space seed experiments come as industrialization eats up farming land and makes it harder and harder to find ways to feed China’s 1.3 billion people.
The nation has experimented with genetically modified crops before. Genetically modified tomatoes, soy beans and corn are already in production. China is also considering plans to start producing genetically modified rice. (AFP)
試圖增加糧食產量的中國準備發射一枚衛星,在太空中協助培育超優質品種的水果、蔬菜和其他作物。
九月初一顆滿載種子的衛星將由火箭搭載升空,進行為期兩週的任務,讓兩千粒種子接觸太空輻射,之後這枚衛星便會重返地球,科學家們也將取回種子。
中國國家航天局局長孫來燕表示,這枚「種子衛星」將有助於科學家試育高產量、高品質的作物。
孫來燕說:「暴露在太空輻射和微重力這類特殊環境下,某些種子將產生變異,進而培育出產量更高、品質更好的物種。」這枚衛星將搭載九種不同的種子上太空。
中國的太空育種實驗行之有年。以往,曾上太空轉了一圈的稻、麥種子,作物產量都提高不少,而太空番茄及青椒種子的作物產量也比一般種子多一到兩成。太空育種的蔬菜作物也含有更多維生素。
然而,九月即將發射的這枚衛星是中國第一顆育種專用衛星。受工業化的影響,農地遭到佔用,要填飽中國十三億人口的肚子愈發困難,中國因而展開太空育種實驗。
中國過去也曾進行基因改造作物實驗,經過基因改造的番茄,大豆及玉米都已量產。中國正考慮開始生產基因改造米。(法新社/翻譯:林倩如)

Let’s explore another delicacy primarily known to Tainan locals: floating milkfish in thick soup. Despite its peculiar name, this dish is another Tainan specialty that showcases the popularity of milkfish, which is made into fish paste and served in thick soup. Unlike the version with tutuo fish, which also adds other ingredients to its thick soup, the floating milkfish version primarily features the “floating fish” itself in its thick soup, ensuring that the fish paste remains the star of the dish. 讓我們來探索另一道台南人熟悉的美食:浮水魚羹。這道菜名奇特的美食,再再展現了台南虱目魚料理的多樣。浮水魚羹是用虱目魚漿做成的羹品,雖然和𩵚魠魚羹一樣是羹湯,但不像𩵚魠魚羹會在湯中加入其他食材,而是讓虱目魚漿成為這道料理的主角。 peculiar (adj.) 獨特的;古怪的 The belly of a milkfish is considered the most
The practice of freezing embryos as part of in vitro fertilization (IVF) was thrown into chaos in Alabama this year, when the state supreme court ruled that such embryos should be considered children, exposing clinics to wrongful death claims in the event they are destroyed in the thawing process. In 2021, more than 80 percent of US IVF procedures involved the transfer of frozen embryos, according to a recent report by the US Department of Health and Human Services. HOW IS EMBRYO FREEZING USED IN IVF? IVF uses high doses of hormones to stimulate ovaries to produce as many eggs as possible. Once
A situation puzzle is a game in which one person describes a scenario and asks the players to explain it. The situation is deliberately lacking in details, but the players may acquire more information by asking questions — however, these can only be answered with “yes” or “no.” A player wins by describing the approximate events that led up to the situation. To do so, they must use a blend of logical and lateral thinking. A famous example of this is sometimes known as “Turtle Soup.” Here’s the riddle: “A man in a restaurant orders turtle soup, tastes it
