Ants have the ability to sniff out cancer in humans, study reveals
Ants have the ability 1_____(sniff) out cancerous cells in humans, a new study has discovered, 2____(suggest) they could 3____(use) for cancer diagnosis in future.
Researchers from the French National Centre for Scientific Research (CNRS) discovered that ant species Formica fusca (丝光褐林蚁) has a well 4____(develop) sense of smell.
It was able to differentiate cancerous cells from healthy cells in humans, thanks 5_____their sense of smell, limited trials revealed. But more clinical tests must be carried out before they could be used in clinical settings like hospitals, the team said.
They suggest that in future, ants could turn out to be better at dogs when 6_____ comes to locating cancerous cells in humans.
7_____(conduct) their research, the scientists performed tests with 36 ants, smelling cells under a laboratory setting.
First, the specialists exposed the ants to the smell of a sample of cancerous human cells. This odor(气味) was then associated with a reward of sugar 8_____(solve).
In a second step, the researchers exposed the ants to two different odors. One was a new smell and the second was the smell of the cancerous cells.
Once this test was 9____(success), the researchers exposed the ants to different cancerous cells.
As such, the scientists found that 'ants discriminate between cancerous and healthy cells and between two cancerous lines.'
After training, Formica fusca ants are able to detect volatile organic compounds emitted by cancerous cells.
'This first study shows that ants have high potential, are capable of learning very quickly, at lower cost, and are efficient,' points out CNRS in a news release.
This isn't the first time that scientists 10____(use) the animal sense of smell to locate cancerous cells.
'Dogs' noses are well suited for medical diagnosis and used for the detection of cancer-specific volatile organic compounds],' the researchers explained.
However, training them to do so requires several months to a year.
On the other hand, 'insects can be easily reared(养殖) in controlled conditions, they are inexpensive, they have a very well-developed olfactory system and hundreds of individuals can be conditioned with very few trials,' the researchers point out.

Why are so many pop songs roughly three minutes long
No matter where you usually hear today’s top hits—the radio, Spotify(流媒体服务平台), a mixtape on your Sony Walkman—you’ve probably noticed that they tend 1____(be ) around three minutes long.
As Vox explains, the custom dates back 2_____ the early 20th century, when shellac(虫蛟的) records first appeared in the market. The rates at 3____ these records spun(旋转) varied, but 78 revolutions per minute (RPM) quickly became the norm. The most popular record sizes were 10 inches—which could hold about three minutes of music per side—and 12 inches, which held 4____(rough) four to five minutes per side. To get radio stations to broadcast their music and get people to buy it, musicians pretty much had to accommodate those time limits.
The late 1940s saw the 5____(bear) of the 45 RPM record(45转的唱片): a smaller, cheaper disc 6____(make) of vinyl (乙烯基)that couldn’t manage much more than three minutes of music per side. Long-playing records (LPs) were introduced around the same time, but it was much easier for radio stations to play single tracks from 45s—which hordes of listeners then went out and bought. While 10-inch 78s had originated the three-minute trend, 45s really helped make it a necessity for radio singles throughout the mid-20th century.
As music technology evolved (进步)over the years, from records to cassette tapes to CDs, three minutes didn’t fall out of fashion as the de facto estimate for pop songs. According to Classic FM, this is partly 7_____ radio stations could fit more commercials into a program if the songs stayed relatively short. Record labels may have favored shorter singles, too, since longer songs didn’t mean fatter royalty checks. It’s also likely that pop music listeners just preferred concision; after all, it’s 8____the last several decades had taught them 9____(expect). As Thomas Tierney, director of the Sony Music Archives Library, told Mashable, “it’s embedded(根植) in our DNA.”
In other 10____(word), success is now less about sales and more about number of streams. Today’s pop stars are making music that reflects the shift—not unlike how 20th-century musicians learned to work within the confines of the original three-minute limit.
