The highest concentration of toxic substances is found in its rhizome.

Cicutoxin works very quickly, after just a few minutes you can observe irritations of mucous membranes and abdominal pain. If a man survives poisoning, it is very likely that he will struggle with damage to the central nervous system for the rest of his life. Unlike other animals, mice can without fear of poisoning eat plant seeds.

KEPLER-442b – Stony exoplanet in superearth class

KEPLER-442b – Stony exoplanet in superearth class

KEPLER-442b – Stony exoplanet in superearth class, which the parent star is the orange dwarf.

ESI: 0,84
Size: 1,3 Earth
Mass: 2,3 Earth
Equivalent temperature: -65°C

The planet KEPLER-442b, from which light has been running for 1115 years, belongs to the so-called Super-Earth. In this way, rocky exoplanets are determined whose mass does not exceed tenfolds Earth. The parent star of this planet is an orange dwarf. The star larger than a red dwarf, but smaller than a yellow dwarf, which is the Sun. This type of star has calmer youth, and therefore does not send its planetary children too much UV. In addition, the planet is in the ecosphere, so it can not be ruled out that the ocean is splashing on its rocky surface. If it has a more complex atmosphere, it does not have to be at the same time a kingdom of cold. According to some calculations, it is the smaller superearth that are most suitable for life, even more than our own planet.

Cicadas life cycle – Eastern US invaded by cicadas

Cicadas life cycle – While the north-eastern states of the US invaded by cicadas in the 17year cycle. The south-east are experiencing the same thing, but in another, 13-year-old. What is the relationship between numbers 17 and 13. This is a prime number. Scientists suspect that these cycles are just that, not to have met with the life cycles of their natural enemies, who live in cycles 2- or 3-year-old. Avoiding in this way any predator that lives longer than one year and less than the same cicadas.
