Meet the popular YouTube science channel "1 Minute Science" in a comic format.

Why has science advanced so much? Because it's so much fun! We've reimagined the iconic episodes of "1 Minute Science," a science channel with over 700,000 subscribers and 60 million total views, into a comic.
Beyond imparting knowledge, this book is packed with exciting science storytelling that makes you realize how fun and important science is.
From everyday topics like coffee, cats, and social media to weighty topics like genes, time, and evolution, this is an amazing science story that will make 10 minutes feel like 1 minute once you get into it!

I created '1 Minute Science' because I felt that scientific knowledge was too important for only scientists and specialists to know.
When I first experienced the wonders of science, it was actually a bit shocking.
I thought, 'Why is no one talking about something this important?'

For Homo sapiens, who appeared on Earth 200,000 years ago, green paper called money and concrete buildings did not exist.
In 200,000 years, who knows what will be called 'reality'?
But whether it's 200,000 years from now or 2 billion years from now, gravity will still be there.
It seems to me more appropriate to say that something that does not change is reality than to say that something that changes without warning is reality.

So I learn about the reality of science.
And I believe that if people truly learned this reality, they would see the world differently.
I look forward to seeing all the people of the Earth looking up at the sky and falling into a state of ecstasy.

About 7,500 years ago, strange humans who could digest cow's milk even as adults began to appear.
In the cold, food-scarce Nordic regions, the ability to digest cow's milk would have been a huge evolutionary advantage, and so the mutant gene began to spread from Europe to the rest of the world.
Currently, about 80 percent of the population in Europe carries the altered gene, while in Asia and Africa, only 20 percent carry it.

When sea squirts are larvae, they swim around in the sea, but when they grow to a certain size, they cling to rocks. When they no longer need to move, they do something strange.
It is eating one's own brain and nervous system to supplement nutrition.

When adenosine binds to adenosine receptors, our body feels tired.
By the way, the caffeine in coffee looks very similar to adenosine.
When we drink coffee, the caffeine that enters our body enters the adenosine receptors where adenosine should enter and binds precisely.

The desire to connect with other Sapiens is a powerful instinct deeply rooted in our brains. Social media has tapped into this instinct, and the brains of Sapiens worldwide have instantly embraced it.
For Sapiens, social media is an incredibly attractive lifeline.

The DNA replication process that occurs in nature is not perfect, and all kinds of replication mistakes are still occurring in the cells in our bodies.
Most mutations do not provide an advantage for survival or reproduction, so they are not passed on to future generations and disappear.

Carl Sagan, who dedicated his life to popularizing natural science, made an ingenious proposal to the Voyager team in 1980.
“Team Leader, this is Sagan.
A good idea occurred to me.
“Before Voyager leaves the solar system, it turns its camera to take a picture of Earth.” “What a reckless guy…”

Conversely, have there been cases of men suppressing testosterone secretion to diminish their masculinity? Have there been men who removed their testicles to extend their lifespan? Research has revealed a surprising number of such cases.
They are the Eunuchs of KOREA.
Let's go!

The most powerful way to stay young without turning into a lobster is exercise.
A study published by Brigham Young University in the United States on April 24, 2017, conducted this survey.
When comparing the telomere lengths of two groups, one group that exercised and the other that did not, with the condition that men jogged for 40 minutes a day and women jogged for 30 minutes five times a week, it was revealed that there was a difference of as much as 9 years in physical age.

We live in a space-time where space and time are combined.
But why do people find it so difficult to imagine a fourth dimension, time? The reason is that our eyes can only see up to three dimensions.

The secret of humanity contained in this sculpture is that Homo sapiens were the first in animal history to begin to think about invisible, illusory beings.
The ability to believe in this invisible being made mankind the rulers of the world.
