A new direction in science: plant nanobionics

After the introduction of carbon nanotubes into chloroplasts, the ability to photosynthesis increased by 30% in plants, and sensitivity to gases polluting the environment also appeared. The scientists attributed their research to a new field, which they called "plant nanobionics".

Low-calorie diet and life expectancy: an evolutionary hypothesis

According to a new evolutionary hypothesis, in the wild, adaptation to a low-calorie diet ensures the preservation of the ability to reproduce in difficult times, and it contributes to an increase in life expectancy only in "greenhouse" conditions.
