Rearchers from the French National Centre for Scientific

Rearch (CNRS) discovered that ant species Formica fusca has a

well-developed n of smell. It was able to

distinguish cancerous cells from healthy cells in humans. But

more clinical tests must be carried out before the findings could

be ud in clinical ttings like hospitals, the team said.

In the rearch, the scientists performed tests with 36 ants,

smelling cells under a laboratory tting. First, the ants were

expod to the smell of a sample of cancerous human cells.

This odor (气味) was then associated with a reward of sugar

solution. Then, the rearchers expod the ants to two different

odors. One was a new smell and the other was the smell of the

cancerous cells. Once this test was successful, the rearchers

expod 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 of cancerous cells.

This study shows that ants are capable of learning very

quickly, at lower cost, and are efficient, points out CNRS in a

news relea. This isn’t the first time that scientists have ud

animals to locate cancerous cells. Dogs’ nos are well suited

for medical diagnosis and ud for the detection of

cancer-specific. However, training them to do so requires veral

months to a year.

A. The rearch tools and methods.

B. The process of the rearch.

C. The application of the findings.

On Mondays, two of my children get ready for school in

an unusual way. Each packs plenty of food and water, a pair

of rubber boots and sometimes a cup of hot chocolate. Then, I

drop them off at a nearby park where they spend the entire day

outside at a certified forest school.

When I first signed them up for forest school program, I

loved the idea, but as a mum, I was concerned about a few

things: Would they be comfortable outside for that long? Would

they stay engaged for that many hours? Then I asked them if

time ever emed to move slowly, they stared at me in confusion.

“What about all the things they’re missing in real school?”

concerned parents have asked me. Neither of their classroom

teachers thinks it’s a problem

but most significantly, my kids are learning new and different

skills that a classroom cannot teach. They are learning to sit

silently and obrve nature up clo-a skill that’s virtually

impossible to develop in a noisy and overcrowded classroom

tting. They are making social connections across a broader

range of age groups. They cooperate together, using their

different sizes and strengths to fulfill various roles within their

games.

I appreciate it that forest school is shaping my boys’

relationship with the outdoors. They’re learning how to spend

extended periods of time in nature, what to do to pass the time,

and developing knowledge that will get them much clor to

nature in the coming decades.
