The relationship between fish and bivalve molluscs is an excellent model system for studying survival and the risk of coexistence in a rapidly changing environment

The project dealt with various aspects of inter-population variability in the success rate of biological invasions and their impact on native species. Experimental and field studies in the areas of invasion and original occurrence were combined. Population genetic studies of both native and invasive species were also an important part of the project. The project was covered by the topic of the relationship between bitterling and host bivalve molluscs.

The most important discovery was the confirmation of the fundamental impact of inter-popular differences in the success of invasions, their impact, but also in the degree of vulnerability of native organisms. This finding may help to explain the known fact that some species may enter non-indigenous areas in the long term without any visible impact on native organisms. Suddenly, however, there is a dramatic change, after which this non-native species has significant negative impacts.

Compared to the situation in Western Europe and the USA, Czech suburbs are not at risk of segregation

During 2014 – 2016, the team led by doc. Martin Ouředníček, the Head of the Research Team of the Urban and Regional Laboratory and Vice-Dean of the Faculty of Science of the Charles University, carried out the GACR project “Dynamics of social environment and spatial mobility in metropolitan regions of the Czech Republic”. The main objective of the project was to examine the dynamics of the social environment, which is influenced by various types of spatial mobility, such as migration or commuting.

The research focused on processes taking place in outer parts of post-socialist cities: residential suburbanization and transformation of housing estates. These processes differ significantly from developments in Western Europe and the United States, and the Czech Republic is quite unique in many areas.

The HelD protein is important for correct gene expression

The project “Deciphering the Cellular Role of HelD, a Helicase-like Protein Associated with Bacterial RNA Polymerase” was a follow-up to the previous project, which focused on the study of several proteins that interact with bacterial RNA polymerase (RNAP) – an enzyme that is crucial for transcription of DNA into RNA. In this previous project, HelD was discovered as a new RNAP interaction partner, and given the central role of RNAP for gene expression that determines a cell’s ability to adapt to environmental changes or pathogens to survive in the host, it was very attractive to further study this protein and to obtain new information on functioning of the transcriptional apparatus.

The Czech Republic is one of the best in the world in the research of space asteroids

There are hundreds of thousands of known asteroids in the Solar System. We have detailed information on only a few thousand of them so far. The Czech Republic is a world power in creating models of these cosmic bodies. The GACR project “A big picture of the main asteroid belt – physical properties of asteroids derived by inversion of optical and infrared photometry” focused on the analysis of data on asteroids. The team led by doc. Mgr. Josef Ďurech, Ph.D., achieved to describe more than a thousand new cosmic bodies.

Model of planet Itokawa

In the area of asteroids modelling, the Czech Republic is the most productive in the world and these models are used by scientists around the world for further research and measurement. The results also serve for further basic research, for example to derive and obtain further information about the asteroid, such as its thermophysical parameters etc.

The project results can be used in the fields of electronics or tissue engineering

Most of us perhaps know that we divide burns by intensity into four basic groups. Even though extensive burns can be fatal, modern ways of treatment greatly improved the treatment results. Scientists are currently working on full replacement of the burnt skin.

One of them is Ing. Alena Řezníčková Ph.D., who has been dealing with this task for three years as part of the project “Physically deposited and anchored metal nanostructures on solid substrate”. The main objective of the project was to modify the surface of the sample, polymer or glass, using physical and chemical methods to improve its properties for medical and electronics applications. The polymeric substrate itself is inert and therefore not suitable for other applications.

Cooperation within CEUS initiative has been started

On Monday 17 June 2019, the highest representatives of GACR, FWF (Austria), NCN (Poland) and ARRS (Slovenia) solemnly signed the “CEUS – Central European Science Partnership” Lead Agency Agreement: Memorandum of Understanding on the unilateral administration and mutual recognition of evaluation procedures. This new cooperation enables scientists from the Czech Republic, Austria, Poland and Slovenia to carry out scientific projects with new foreign partners based on the Lead Agency evaluation, which is among the increasingly preferred forms of cooperation between foreign agencies supporting basic research due to reduction of administrative burden. Within the CEUS initiative supporting basic research in the Central European region, scientists will be enabled to submit bilateral and also trilateral project proposals on the LA principle.

GACR President’s award for excellent research 2019

Five Principal Investigators of the top basic research projects received the GACR President’s Award 2019. In contrast to last year, when one female investigator was awarded, male investigators dominated this year’s award.

Zdeněk Sofer succeeded with a project investigating the application of ion beams for modifications of graphene-based structures. Jiří Bruthans examined the effect of gravity-induced stress on sandstone erosion. Marek Mráz’s project focused on studying the regulation of B cell receptor (BCR) signalling pathway by microRNAs. Laureate Václav Štětka analysed the role of social media in transformation of political communication and citizen participation in the Czech Republic. Another laureate, Robert Černý, focused on oro-pharyngeal interface during vertebrate primary mouth formation. The GACR presidium decided on the winners among dozens of different projects.

“Yet again, choosing the best projects has been extremely difficult this year. We face the challenge of selecting the best projects among dozens of projects every year. On the other hand, it is a good message on how brilliant scientists in our country are. Congratulations to award winners, their projects were indeed excellent,” Alice Valkárová, the GACR president, stated.

The GACR President’s Award was established in 2003. Since then, 69 awards have been given in response to the excellent results in carrying out basic research projects supported by GACR. This year’s five awarded projects were selected out of 448 projects that ended last year, based on proposals of the respective discipline committees. The GACR presidium decided on the final selection of projects for the GACR President’s Award this April.

The prize is awarded for excellent results in basic research projects that had been supported by GACR. The Principal Investigators of the chosen projects and their co-workers receive a financial reward. Every year, the award goes to four to five Principal Investigators, whose projects were completed in the previous year, received a nomination for the award and acquired excellent evaluation by expert advisory bodies.

Determination of chemical molecular structure, the chirality and the electronegativity of atom

doc. Ing. Pavel Jelínek, Ph.D.

Doc. Ing. Pavel Jelínek, Ph.D. from the Institute of Physics of the Czech Academy of Sciences together with his team was able to differentiate chemical structure of molecules on the surface of solid substance. The scientist developed comprehensive physical mechanism theory of this scanning. The key for obtaining this sub-molecular contrast is the placement of one molecule (e.g. carbon monoxide) or atom at the end of the metallic probe. The presence of the flexible particle at the end of the probe causes the strengthening of the signal which then enables to achieve unprecedented resolution of the molecules. This new method also proved the validity of the equation of the Nobel Prize winner Linus Pauling for the covalent bond from the 1930s.

Parrots and corvids are clever due to the extreme high number of neurons in their cerebrum

Mgr. Pavel Němec, Ph.D.

Project of Mgr. Pavel Něměc, Ph.D. from the Faculty of Science, Charles University in Prague revealed the anatomical nature of bird intelligence and therefore solved the mystery why some birds are extremely intelligent although their brains are small. The research of Mgr. Pavel Němec, Ph.D. proved that small brains of birds contain substantial number of neurons. Despite the fact that the largest brains of Passeriformes weigh around 16 grams and the largest brains of parrots weigh about 25 grams, the brains contain equal number of neurones as primate brains which are significantly larger. This research proved that neither absolute nor relative size of the brain is a proper measure of cognitive abilities. It is rather dependent on the cellular composition and neural density. The results of the research were reported by the media worldwide.
