Scientists from the Institute of Physics of the AS CR, together with colleagues from Spain and France presented in the journal Nature Communications new theory of the origin of polyaromatic hydrocarbon molecules in the universe. According to the new theory, these molecules are formed by hydrogen etching of the graphitic surface of the stardust particles.

On Tuesday, 21st of January, 2014 Nikon Company in the cooperation with the Institute of Molecular Genetics, Czech Academy of Science, will start operation of a new Nikon Centre of Excellence in Super Resolution Microscopy. The Super Resolution Microscopy is a revolutionary microscopic method enabling the observation of the smaller details especially in the cell biology, than it was possible until now with the conventional methods.

20 Years of the Academy of Sciences of the Czech Republic

4 Dec 2013

On the occasion of the 20th anniversary of the creation of the Academy of Sciences of the Czech Republic, there was a press conference in the Prague headquarters of the most important Czech scientific institution. The history of the Academy of Sciences of the CR with an emphasis its essential role in society, breakthrough moments and main developmental stages was first raised by its current president, Prof. Jiří Drahoš. It was then commemorated by his three predecessors in the leading post of the ASCR – Prof. Rudolf Zahradník, Prof. Helena Illnerová and Prof. Václav Pačes.

Epigenetic diversity increases the productivity and stability of plant populations

Humanity is dependent on natural ecosystems as sources of food, but they also provide other essential services. The preservation of biological diversity is a fundamental challenge for contemporary environmental protection. Recent research has found that intraspecific diversity plays an equally vital role in the functioning and stability of ecosystems as interspecies diversity. Intraspecific diversity was until now always attributed to phenotypic and functional diversity of individuals, secured thanks to the variability of DNA. Nevertheless, the phenotype is controlled only by the base sequence of nucleotides in the DNA, but is also controlled by epigenetic variation.

Why does the cuckoo win the battle with its host?

New knowledge from biologists of the ASCR
The Common Cuckoo is an obligatory brood parasite that lays its eggs in the nests of other bird species (hosts), and leaves them with the entire burden of raising their offspring. As a consequence of this way of life, a number of specific adaptations have arisen, to which the hosts respond with adequate counteradaptations. That leads to the emergence of a coevolutionary struggle between the two involved parties. One of the most interesting adaptations of the Common Cuckoo is the often noteworthy similarity of their eggs to the hosts’ eggs (mimicry), which increases the chance that the host does not recognise and remove them.

Czech Astronomers are the first to have captured the optical afterglow of a gamma burst

20 Nov 2013

On 30 October at 10 PM, a so-called gamma burst flared in the constellation Aquarius. It was recorded in space by the satellite Swift. Astronomers from the Group of Astrophysics of High Energies Group of the Stellar Section of the Astronomical Institute of the ASCR started monitoring it only 41 seconds after the placements of the optic telescope at the observatory in Ondřejov and were so the first in the world. They are gigantic energetic flashes in the area of gamma radiation, which energy comparable with the emission of the Sun for its entire lifespan is released over a few seconds or tens of seconds. The distance of the object in space was calculated as 9 billion light years.

18 Nov 2013

Representatives of the Academy of Sciences of the CR were again successful in the prestigious scientific competition Česká hlava (Czech Intellect). The National Prize of the Government of the CR Česká hlava 2013 was obtained by the outstanding Czech historian prof. PhDr. František Šmahel, DrSc., dr.h.c. mult., from the Institute of Philosophy of the ASCR - Centre of Medieval Studies. The Prize of the Company Kapsch for Invention was taken by Ing. Ilona Müllerová, DrSc., from the Institute of Scientific Instruments of the ASCR for long-term and systematic research in the area of electron microscopy and the Prize of the Ministry of Education, Youth and Sports of the CR was received for his scientific work within his doctoral study programme by Mgr. Ondřej Maršálek, PhD.

Copenhagen 6 November 2013: The 7th annual SHARE Symposium in Copenhagen, Denmark on 6 November 2013 has the pleasure of welcoming two keynote speakers. In the morning Professor Bente Finsen, University of Southern Denmark, gives a presentation on “Understanding disease mechanisms in human neurological disorders through studies of mice”, and in the afternoon Professor Helena Tlaskalova-Hogenova, Academy of Science of the Czech Republic, gives a presentation about “The role of microbiota in the immune system development and chronic disease”.

Week of Science and Technology of the ASCR – A festival fascinated by the world

30 Oct 2013

The largest science festival in the Czech Republic Week of Science and Technology of the Academy of Sciences of the CR was ceremonially opened today at the headquarters of the ASCR in Prague with the attendance of President of the ASCR Prof. Jiří Drahoš and Lord Mayor of the Capital City of Prague RNDR. Tomáš Hudeček. This, already the 13th annual festival of successful scientific shows, whose popularity is still growing, bears the subtitle Fascination with the World. It is taking place on 1–15 November 2013 and its programme is filled with more than 500 events scattered all over the Czech Republic.

New approach to preparation of highly tunable microwave dielectrics

/sys/galerie-obrazky/news-2013/131021-cesti-fyzici-prispeli-k-vyvoji-unikatniho-materialu.wide.jpg

21 Oct 2013

Scientists from Institute of Physics ASCR contributed to development of a new approach to preparation of highly tunable microwave dielectrics exploring Srn+1TinO3n+1 with layered perovskite crystal structure. This material has in the form of 50 nm thin films and under mechanical strain excellent dielectric properties, which are promising for applications in microwave electronics, e.g. in cellular phones. The paper, describing unique properties and preparation of biaxially strained thin films of Srn+1TinO3n+1, was published in Nature journal on 16th October 2013.
