This program is brought to you by the Ogawa Seiki, a company that is familiar with the world's OS engines.
In 1911, the first small engine was released in Japan and it was exported to the United States.
In 1913, the Marine engine was developed.
The next generation, looking at the small engines for more than 40 years, just walked this road.
OS engines, which always lead the world of small engines.
Today, we are in the research room of Kobe University.
Today, we would like to ask you about how the flies taste.
Today's speaker is Mr. Amakawa Taisaku, a professor of biology at Kobe University.
When we put food or sweets in our living room, flies fly right away.
How does it work?
When we look for food, we mainly smell it.
How much is it?
It depends on the animal, but it is a few meters.
Is it the same for other insects?
Yes, it is the same for cockroaches, but it is also the same for bees.
When a fly comes to eat, it eats the food of its favorite taste.
How do you distinguish it?
There is a period when it is sensitive to taste.
There is a part of the mouth that has a lot of hair.
This part of the mouth?
Yes, this is the mouth.
It feels the taste of the food.
When you walk around and put your feet in something sweet, you feel the taste of the food.
There is a period when you feel the taste of the food.
It is strange to feel the taste of food in the feet.
When a fly comes to eat, it feels the taste of food.
How do you feel the taste of food?
When a fly comes to eat, it feels the taste of food.
Where does this part of the mouth go?
This is the mouth.
When you enlarge the mouth, it goes to the side.
There is a lot of hair in the mouth.
This is the period of the taste of food.
The same thing is on the foot.
Do you touch the mouth?
I have just explained about hair, but I have expanded it.
I have researched it with various electronic microscope and other normal microscope.
This hair is this.
It is facing up.
It is long, but I have summarized it.
This yellow color is the sense organ.
The sense organ is stretched out.
You feel the sense organ.
It is a special organ.
In this case, I feel the taste of food.
The middle of the hair is hollow.
The middle part is flat.
On the other hand, there is a sense organ at the end.
It is at the tip.
It is not just hair.
There is a hole at the tip.
So something comes in from here.
Yes, something sweet.
When the liquid comes in, the sense organ is here.
The reaction occurs there.
The electric changes occur.
It is transmitted here.
What is this 4?
Each has its own taste.
It can be sweet, spicy, or watery.
It is different.
It is a sweet thing.
It is sweet.
The next one is salty.
It is spicy.
It is salty.
The other one is watery.
It is just water.
There is a root at the end.
What about the other one?
There are many other types.
It is fat.
It is relatively small.
It is called a liver organ.
It is not fully discovered yet.
It comes in here.
It reacts around here.
How did you know this?
This is what you are studying.
The state of the sense organ is expressed as an electric change.
An electric change?
The electricity is flowing.
It is flowing like this.
It is a very fine wave.
It is a wave that goes through here.
It goes to the brain.
It is a very fine and fast change wave.
The wave is a signal.
For example, a substance called sugar is coming.
We can see how fine it is.
It is a signal.
The electricity is flowing.
This is a very fine glass.
It is a very fine glass.
It is not much different from us.
For example, if you melt sugar in 100 ml of water,
you will feel the sweetness.
In the case of humans,
if you melt 4.5 g of sugar in 100 ml of water,
you will feel that it is somehow sweet.
In the case of flies, it is about 3 g.
There is another very important thing.
The butterfly, which is called the red-tipped butterfly,
can feel the sweetness just by melting 0.002 g of sugar.
It is a very important thing.
That's right.
In the case of flies, they usually gather in dirty places.
In our environment, that's right.
We are looking for food by smelling it.
In our case, what flies like is usually polluted food
and rotten food.
In the end, that's the only place where flies live.
In the case of flies, they kill the cows and eat the fresh meat.
That's right.
They eat the food that someone killed and left to rot.
What is this fly?
This is a blowfly.
It is called a black gold fly.
Is it in Japan?
This is a standard thing that was imported from the United States.
It is a standard thing used by researchers who study the management of the world.
I have been buying it.
There are many types of fly that are made in the same type all over the world.
However, it is easier to discuss with researchers in the same type.
In Japan, black gold flies are said to be in the Tohoku region of the U.S.
There are many countries that use the same type of fly.
I'm looking at it and it's rubbing.
That's right. It's rubbing against the hill.
What does this mean?
This is related to what we talked about earlier.
This is a sense organ.
There is a hole at the tip and it is used to feel the air.
For example, it is used to feel the air in the meat.
This is a big part of the body and it is used to collect garbage.
When this is used, the sense organ is not used.
This is a clean organ.
The fly likes clean things.
In that sense, it may like clean things.
It is always clean.
How is it?
I think the fly is dirty, but it has an unexpected side.
Thank you for your interesting story.
Thank you.
The OS Live Steam Center is receiving your questions.
Please contact us.
We are waiting for your questions.
People have been dealing with various machines for a long time.
Eventually, the organ organ was born and it traveled the world.
50 years of loving organ organs, OS continued its research.
Live Steam Locomotive is the king of small engines.
