Usually, the farther away from the heat source, for example candle flame or stove, the cooler it gets. But it is different on the Sun. The solar corona is much hotter than the layers closer to the solar core. Scientists have long wondered why this was happening. Now they have shown that the solar corona can be heated by the so-called Alfvén waves.
Chemical computers are becoming ever more of a reality - this is being proven by scientists from the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw. It turns out that after an appropriate teaching procedure even a relatively simple chemical system can perform non-trivial operations. In their most recent computer simulations researchers have shown that correctly programmed chemical matrices of oscillating droplets can recognize the shape of a sphere with great accurac
Fever, which helps in the fight against disease, occurs not only in warm-blooded animals (such as mammals), but also in fish. And body temperature in fish depends on the ambient temperature. Researchers from the Jagiellonian University looked at the so-called behavioural fever in fish.
The creators of gardens invite to experiment this spring. Instead of the traditional geraniums on the balcony, they propose to plant fruit shrubs, vegetables and vines that bear original fruits - such as gourd.
We now know how to perform genetic recombination - shuffling genes in the process of creation of reproductive cells - significantly more effectively than before. It will allow to obtain new varieties of plants faster and more cheaply.
Selected specialized bacterial strains help clean lakes and ponds under aerobic conditions. Thus harnessed microbes can clean water in a reservoir with a biologically safe method in less than six months.
Minister of the Environment Prof. Jan Szyszko said that Bulgaria wanted to receive six bison from Poland, and assured that they would receive the animals. He noted that other countries responded that they were not ready to restore the habitats of bison in Europe.
Some predators that prey on molluscs make holes in their shells, very similar to the holes in the shells found by archaeologists at the sites associated with prehistoric people. Scientists from Poznań and Liverpool recently investigated this issue.
The number of geese increases in the Warta River Mouth National Park. It is a sign that spring is near and we should not expect the return of frost. Until recently there were only 7 thousand geese in the park, now their number exceeds 37 thousand.
Internet users around the world will be able to see the animals and plants of the Białowieża Forest. 1400 research plots have been designated and inventoried - Minister of the Environment Jan Szyszko said last week on Thursday.
