How warm and cold water mix

Warm water is less dense than cold one. And anything that is less dense tends upwards, while anything that is more dense tends downwards.

Well, maybe, do we have some genes responsible for the degree of a person's industriousness?

It's just that some people seem to lack it, while others have it hypertrophied😁

And if we go deeper into this question, we do find such a pattern in heredity.
The "industriousness" gene (under a slightly different name) is one of the "big five" according to the generally accepted classification of human temperament.

Five complex characteristics have been identified, and they all have high heritability: extraversion, neuroticism, benevolence, openness to experience, and conscientiousness.

Hard work is 40-60% determined by genes🧬
And the remaining percentage is determined by the characteristics of the environment, culture, upbringing. That’s a very high degree of inheritance, and it can have a significant impact on a personality.

Soft robot for exploring the Mariana Trench

Chinese researchers managed to solve the problem of high pressure on the robot body at great depths.

They chose not to strengthen it, but instead made the construction from soft polymer and silicone. The bot's electronics is now distributed all over the robot's body, thus reducing the high load.

As a result, the robot performed well during tests in the Mariana Trench.
