Pregnancy tests were in Ancient Egypt. And they worked
3 500 years ago, women wanted to know whether they are pregnant. According to the text on papyrus, which dates from 1400 BC, pregnancy tests were still in Ancient Egypt. Women have used the seeds of wheat and barley. Had to urinate on them, and if at least one type of grains germinated, this meant that soon the woman will probably become a mother.
If the barley grew faster, the Egyptian woman was expecting a boy, if wheat, then the girl. There was even a study in 1963, which showed that the pregnancy test is accurate in 70% of cases, but the method of sex determination have not shown the same impressive results. Scientists suggest that this old test worked well, because the elevated level of estrogen in the woman’s urine could contribute to the growth of the seed.
Caterpillars turn into a “soup” before becoming butterflies

The stones can be solar panels
It turns out that solar panels exist in nature. In 2019, Anhui Lu from Peking University have discovered electric currents on the surface of some desert rocks that have a thin coating of iron and manganese. The study showed that there is a relationship of light and energy: the less light, the less current. One of the ways to use this discovery, the possibility of improving the existing solar panels.
