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.
Fragment of a meteorite, fossils, plant seeds, human DNA, tardigrades, coins, photos of the Earth, silicon crystals - are the treasures buried by Polish scientists in a time capsule on Spitsbergen. The container is designed to appear on the surface of the Earth in about 500 thousand years.
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.
How is it possible that life exists on Earth? And that from ordinary elements compounds have formed that can multiply and store information? Simulations on supercomputers help test the hypotheses that explain these phenomena - told PAP bioinformatics expert Prof. Jacek Błażewicz.
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.
Rainy weather does not mean that something extraordinary happens in the atmosphere; at this time of year we have a large variability of conditions - told PAP atmospheric physicist Prof. Szymon Malinowski, commenting on heavy rainfall that occurred in many regions of Poland in early May.
