POPULAR SCIENCE HAS A BRIGHT FUTURE

The popularity of science-popping or popular science groups suggests Chinese people are becoming more science-literate, writes Zhang Zhouxiang and Wang Xiaoying

Evolution does not necessarily lead to stronger or smarter species. Some species survive the competition for life because they have a unique advantage: Low consumption of energy.

A kind of green alga perfectly fits this logic. Its organic structure is so simple that it has to rely on another kind of bacterium for circulation. The latter takes care of its consumption of energy, disposal of waste, as well as supports its basic life.
