Just four plants - wheat, rice, maize and soybeans - account for 60 percent food produced worldwide. In the face of catastrophic climate change, a larger diversification of cultivated plants is needed, says Prof Sayed Azam-Ali from the University of Nottingham, UK.
Why do seeds not germinate in the last hot summer day? How do they "know" they should still wait? This is one of the plant genes\' doing. It is being studied by researchers from the Institute of Biochemistry and Biophysics PAS. On the example of this gene they draw important conclusions about information processing in the cell.
Herbalism is best used as a therapy supporting treatment with synthetic drugs - explains Prof. Ewa Osińska from SGGW-WULS. While common cold can be treated with herbal infusions, chemical drugs are needed in more serious illnesses. Herbs can support this therapy, strengthening the effects of medication or alleviating side effects.
Can a carbon dioxide molecule be bent with metal atoms and converted into something chemically useful? How to influence the gas to make it more susceptible to chemical transformation? Studies on CO2, as well as structural analysis of proteins - such as pancreatic digestive enzymes - are enabled by analytical technique called mass spectrometry.
The occurrence of severe frosts in winter and heavy rains in the summer in Central and Eastern Europe can be influenced by the weather in the tropics, especially the Malay Archipelago. Scientists want to see how strong is the link between the Malay Archipelago climate and extreme weather phenomena in Europe. One of the results of their work could be more accurate long-term weather forecasts.
Are amino acids in the standard genetic code encoded optimally? Not necessarily! Studies indicate that it would be possible to encode them so that any error in reading the protein coding sequence was less of an issue for the body than it has been until now - said geneticist Dr. Paweł Mackiewicz.
