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 - Cicada

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.

Contact pesticides – Increases risk of autism

Contact pesticides - Monsanto pesticide to be sprayed on food crops.

Contact pesticides – Increases risk of autism

Contact pesticides – Research shows that exposure to pesticides during pregnancy increases the risk of developmental disorders in children (including autism) and cardiovascular disease later in life. These substances are also associated with obesity and diabetes. The European Commission after reviewing studies of pesticides in 1000, ordered to withdraw from the market approx. 700 of them.

Syllogomania – Mental disorder pathological collecting

Syllogomania – Mental disorder pathological collecting – According to the classification of mental disorders American Psychiatric Association throwing old stuff makes trouble every fifth person, and the problem of pathological collecting (syllogomania) applies from 2 to 6 percent of the population of the United States and Europe. The first symptoms appear in the teenage years and worse with every decade of life. Although the causes of disorder are still unknown, the patient requires psychiatric help. 75% of pathological collectors had also suffer from anxiety disorders and more than half are diagnosed with major depression.

Martian life – Theoretically it is possible

Martian life – Could exist only in the first 600 million years of its existence. At least, so say scientists from the University of Rhode Island. Climate that prevailed at the time on Mars was wet and warm, experts believe. Theoretically, it is therefore possible that life arose here. Unfortunately, over time the planet dry and reigned on the hostile conditions in which they could not survive even the simplest organisms. Team of researchers came to these conclusions based on the analysis of mineral samples from Mars. The change came about. 4 billion years ago and was most likely the result of volcanic eruptions. Since then, the minerals formed without the aid of water and are very rich in iron.

Soil formed continuously – Erosion is natural process

Soil formed continuously - Water erosion

Soil formed continuously – Erosion is natural process

Soil formed continuously – Erosion is natural process – Despite this, we consider it a non-renewable source. In comparison to the length of human life is not renewed fast enough. Formation centimeters of the soil takes hundreds of years. It is also a limited source. Now everything depends on how it is used. Currently, each resident of Poland belongs approx. 0.4 ha of farmland. Agricultural area decreased in the last hundred years. The fields were created factories and enlarging cities. This is not only unfavorable factor. Another reason is water erosion. Fertile soil is washed away and disappears forever. Erosion is a natural process, but human intervention in the landscape several times increases the impact.
