The scientists in Mosa Meat, a company in the Netherlands, grow meat in a lab. It looks just like the meat you buy in a supermarket.

Why are people making lab-grown meat? It might be better for the environment. Most meat comes from animals that are raised on factory farms. The animals are crowded into a small space. A lot of gas is produced and makes the climate worse.

Johanna Melke is a biologist(生物学家) at Mosa. “People want to eat meat and we can grow meat in a lab,” she says. “This is how we solve the problem.”

To produce the meat, a tiny piece of muscle(肌肉) is taken from a cow first. It doesn’t hurt much. The muscle is taken to a lab and put into a special broth(液体培养基) that helps the muscle grow. From this, something like hamburger meat is made.

Mosa is not the only company to do this. More than 70 companies make more than just beef. They can grow meat from a chicken, fish, even a mouse. That’s used to make cat treats.

Mark Post helped set up Mosa Meat. He says people know that factory farming can be harmful, but it’s hard for them to give up meat. “I wanted to make the choice for those people easier,” He says.

So how does lab-grown meat taste? Laura Jaekisch is a scientist at Mosa. She abandoned meat years ago. She tasted Mosa’s lab-grown beef. “I started loving beef again.” she says.

A dozen Chinese dishes have become popular during the Beijing 2022 Olympics, after athletes shared them on TikTok and in media interviews. Let’s take a look at some of them.

■ Red bean bun(红豆包)

Snowboarder Jenise Spiteri, the only athlete standing for Malta, is a big fan of Chinese food. “One morning I was too nervous to eat any food. So I put some red bean buns in my backpack. I didn’t realize that I still had one in my pocket when I did the run, so I was like ‘Oh, okay! Now I can finally eat’,” she recalled.

■ Kung Pao Chicken(宫保鸡丁)

American snowboarder Tessa Maud has become popular in China for sharing Chinese food from the Olympic village on TikTok. Beijing 2022 proved to be a totally new and enjoyable experience for Maud. What to eat was a daily hard choice for her because everything was so good.

■ Chinese dumplings

American athlete Julia Marino, who won a silver medal in women’s snowboard slopestyle at the Beijing 2022 Winter Olympics, told NBC News that her favorite food in the Winter Olympics village was dumplings.

“I’ve probably had like 200 dumplings since I’ve been here,” said Marino.

■ Spicy hotchpotch(麻辣烫)

Jutta Leerdam, a 23-year-old speed skating athlete from the Netherlands, posted her favorite spicy hotchpotch on social media. “This is the famous Chinese snack spicy hotchpotch, which is healthier than burgers and fries,” said Leerdam.

The Games provided global athletes with 678 dishes from all over China, allowing them to fully experience the Chinese food.
