Quantifying the impacts of alien species: towards an IUCN Black List

One of the major transformations of the planet from human activities is the wholesale redistribution of species, through the deliberate or accidental translocation of their populations to areas outside their native range. These “alien” species have in many cases caused substantial deleterious impacts to the recipient environment (e.g. extinctions of native populations and species, the disruption of soil nutrient and water cycling, and natural disturbance regimes). Preventing and mitigating such impacts is a major drain on limited conservation resources.

The FUNBIO project – studying materials on the boundary of life

7 May 2014

Institute of Physics, CAS, v. v. i. (FZU) has begun implementation of the Center of functional materials for bio-applications (FUNBIO). This project is supported within 11th call of the OPPK (Operační program Praha – Konkurenceschopnost; Operational Programme Prague Competitiveness) structural funds of the European Commission, which significantly complements the current project Centrefor Analysis of FunctionalMaterials (SAFMAT).

New findings on acute myeloid leukemia from the Institute of Molecular Genetics CAS

5 May 2014

Scientists from the Institute of Molecular Genetics of the Academy of Sciences in Czech Republic (IMG), in collaboration with several leading centers in the USA and the Netherlands, clarify the mechanism of transformation in one subtype of leukemia. Importantly, they identify substances that in a future might help to develop more effective treatments for this disease. The results of this study were published in the international journal Haematologica.

Physics helps economy: a new monograph on Econophysics from the Institute of Physics, CAS

12 Mar 2014

Importance and impact of methods and techniques developed for studying physical problems has outreached the realm of natural sciences. Methods of quantum physics and statistical mechanics find more and more applications in biology, economy, informatics, or sociology. Physics has become one of the most important components of a number of new interdisciplinary research fields. Econophysics utilises methods of statistical mechanics and theory of phase transitions to model and understand processes in economy and financial markets.

Brain Awareness Week

10 Mar 2014

Every March, the European Dana Alliance for the Brain (EDAB) coordinates Brain Awareness Week, when hundreds of public events in dozens of countries celebrate progress in brain research and inform the general public about their overall results. In the Czech Republic, Brain Awareness Week activities are organized by the Institute of Experimental Medicine CAS and by Czech Society of Neuroscience, by the Centre of Neuroscience and by the Centre of Administration and Operations CAS.

 

Relativity shakes a magnet

Researchers from Institute of Physics CAS demonstrate a new principle for magnetic recording

Current technologies for writing, storing, and reading information are either charge-based or spin-based. Semiconductor flash or random access memories are prime examples among the large variety of charge-based devices. They utilize the possibility offered by semiconductors to easily electrically manipulate and detect their electronic charge states representing the “zeros” and “ones”. The downside is that weak perturbations such as impurities, temperature change, or radiation can lead to uncontrolled charge redistributions and, as a consequence, to data loss.

Magnetic inside but not on outside

Researchers from the Institute of Physics introduce antiferromagnetic memories
 
In ferromagnetic materials, information can be stored in “zeros” and “ones” defined by the orientation of magnetic moments, which can be pictured as small compasses (see Fig. 1a). This technology is behind a range of memory applications from kilobyte magnetic stripe cards to terabyte computer hard disks. It is dangerous to place a parking ticket or a hard disk next to another magnet or device generating strong magnetic fields because the magnetic moments of the memory can be unintentionally reoriented and the information lost (see Fig. 1b).

A new theory explaining the origin of hydrocarbon molecules in interstellar space

22 Jan 2014

Scientists from the Institute of Physics of the CAS, 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.

New Nikon Centre of Excellence in Super Resolution Microscopy at the Institute of Molecular Genetics of the Academy of Sciences, Czech Republic

22 Jan 2014

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 CAS – Prof. Rudolf Zahradník, Prof. Helena Illnerová and Prof. Václav Pačes.
