2 . Over the last 60 years, the size of farm machinery has been increasing. For example, from 1958 to 2020, the typical weight of a fully loaded combine harvester for corn or wheat increased nearly ten times.
In a way, it’s fantastic if you see how much we can harvest in a certain amount of time today and how long it would have taken us 60 years ago. Some wheat harvesters, for example, can clear 30 acres in an hour. That incredible efficiency enables about 5 percent of the world’s population to feed the other 95 percent.
But it is at the soil’s expense. One recent study reported that soil compaction (土壤板结) from heavy machines has reduced yields in some fields by as much as 50 percent. If current trends continue, it may eventually reduce global crop production by as much as 20 percent.
“Healthy soil is alive. A teaspoon of garden soil might hold a billion bacteria and networks of air pockets. Heavy farm machinery squeezes the life out of that rich soil by compacting it at depths of a foot or more, lowering oxygen levels and destroying the life that creates the basis for healthy soil. Once damaged, heavily compacted soil can take decades to recover, if it recovers at all.” says Paul Hallett, a soil physicist at the University of Aberdeen, in Scotland.
Farm machinery makers have tried to limit the impact on the soil by equipping heavy vehicles with fatter tires, which distribute the load more widely and keep the vehicles from sinking too deeply into the soil surface. “But if you have a heavier load, the stress decreases less quickly with depth.” says Paul Hallett. “It is a bit like the way tall chimneys on a power plant spread air pollution far downwind.”

3 . Huge crowds are forming on Monday at the US Botanic Garden in Washington, DC. Usually, it’s a place to see flowers that look pretty, smell fantastic and bloom (开花) annually. But today, the so-called “corpse plants” on show are the opposite in all aspects.
Native to the rain forests of Sumatra, Indonesia, the corpse plants don’t bloom on a regular cycle -- the length of time between blooms ranges from a few years to a few decades and they are ugly and smelly.
“Last night it started out like a good French cheese, stinky but delightful. Then it moved on to a lazy boy’s socks. At last, it was junior high school gym followed by full-on rotten fish. Finally, it moved all the way to a rotting meat smell that was so thick and heavy that I experienced a sore throat, burning eyes and had a bitter taste in my mouth.” said John Clements, one of the garden employees,
“It smells bad to us, but it smells great to flies. It makes them think there’s rotten meat somewhere to lay their eggs, and that helps the corpse plant to get pollinated (授粉),” says Rob Raguso, a professor at Cornell University. “Since it takes a lot of energy for the plant to produce the smell, it puts it on reserve during the day, and will put it out in full strength from 9 pm to 3 am when the air is still and the smell can travel more easily.”
The smell comes from a number of chemicals that smell differently on their own, and that together draw flies to the plant’s cup-like flower. One of these, timethylamine, smells like rotting fish. Another, isovaleric acid, is responsible for the terrible smell of sweaty gym socks.
“It also heats up. The flower actually reaches human body temperature, making it all the more convincing to flesh-loving insects,”adds Rob Raguso.

4 . Zhou Youguang was the inventor of Pinyin, a spelling system that converts (转化) Chinese characters into words with the Roman alphabet. The system, adopted by China in 1958, gives readers an important tool to pronounce the Chinese characters that they are unfamiliar with.
While it is not the first system to Romanize Chinese, Pinyin has become the most widely accepted tool to teach a language that has disparate dialects in different parts of China.
Beyond China’s borders. Pinyin allows the standardization of Chinese names. For instance, it’s a big reason why the name Westerners commonly use for the Chinese capital has shifted from “Peking” to “Beijing”. And it’s why many other such names have changed dramatically along with it.
And yet Zhou, the man behind one of the most important innovations in the 20th century, said he was unwilling to take on the task in the mid-1950s. At the time, he was an economist and only recently returned to China.
“I said I was an amateur and that I couldn’t do the job,” he told the BBC in 2012, laughing. “But they said, ‘It’s a new job. Everybody is an amateur.’ Everybody urged me to change professions. So I did. In 1955, I abandoned economics and started studying writing systems.”
The committee led by Zhou spent three years working on its alphabetic system. “Some people made fun of us, joking that it had taken us a long time to deal with just 26 letters,” he said in the interview.
Others took the committee’s invention very seriously, however. The Chinese government immediately introduced Pinyin in schools. The international community eventually adopted it as the standard Romanization for Chinese writing, as well, with the United Nations doing so in 1986.
Before the invention of Pinyin, 85% of Chinese people could not read. Now, about 95% can read. Pinyin has also played a vital role in determining the ways mobile phones and computers recognize Chinese characters.
