Could thousands of species of animals on Earth can go extinct unnoticed? Many species from hardly accessible depths remain undiscovered. Therefore, there is a fear that human activity will lead to extinction of their predominant number before they are discovered, marine biologists alarm.
Many animals get killed by cars; this problem also concerns monkeys. In the latest "Mammal Review", scientists from the University of Life Sciences in Poznań presented information on nearly 370 collisions with 46 primate species from 4 continents. They sourced the data from the Internet.
Microorganisms, spiders, barley seedlings and new materials have been sent to the stratosphere by scientists from the University of Silesia, who want to check how the conditions in the stratosphere will affect them. The initiative was awarded during the Global Space Balloon Challenge 2019.
The smallest structures of a living organism can be watched "at work". Researchers have obtained sharp images of working and communicating cells. The innovative imaging methods have been developed by Prof. Maciej Wojtkowski`s team from the Institute of Physical Chemistry of the Polish Academy of Sciences.
Strong UV radiation penetrated the atmosphere of the young Earth that did not contain oxygen, and thus - ozone. In such conditions, the first biomolecules formed: the basic building blocks of life. They still exist, forming DNA and RNA. Dr. Rafał Szabla from the Institute of Physics of the Polish Academy of Sciences in Warsaw conducts research on the influence of light on the chemistry that could produce biomolecules.
