Czech scientists solved the enigma of coexistence of people with Rh+ and Rh- blood groupsBefore the advent of modern medicine, about 10 000 Rh positive children born to Rh negative mothers were dying for hemolytic anemia in the US each year. Without the superiority of the heterozygotes – the carriers of both variants of Rhesus gene, the less abundant allele should be quickly eliminated from any population. Jaroslav Flegr probably solved 80 years old enigma of coexistence of carriers of two variants of Rhesus gene in the same population. Published Jan 31, 2016 |

Do we know how newly introduced cultural crops are influencing the soil?Soil is an important provider of ecosystem services, among the most important of which include the possibility of food production and the mitigation of climate change effects. This is made possible through carbon sequestration and nutrient cycling, which are processes primarily driven by soil biota. However, the intensification of agricultural production caused by the growing demand for biofuels reduces the soil biota. We are used to producing oilseed rape, Miscanthus and hybrid sorrel (Rumex patientia x R. tianshanicus) as biofuel plants. While the first two crops are already established in our country, we have very little information so far about the effects of the long-term cultivation of hybrid sorrel on soil organisms.

A way to discover the true species diversity of single-celled organisms?What is the true diversity of organisms on our planet? That is the question that keeps many scientists awake at night. Interestingly, until now many more macroscopic organisms have been described than the very smallest ones, invisible to the naked eye. But one would probably assume that those tiny organisms will be more abundant as they have obviously had much more time for their differentiation. Published Oct 06, 2015 |
