Under the leadership of Petr Cígler from the Institute of Organic Chemistry and Biochemistry and Martin Hrubý from the Institute of Macromolecular Chemistry, both of which are part of the Czech Academy of Sciences, a team of researchers has developed a revolutionary method for the easy and inexpensive production of irradiated nanodiamonds and other nanomaterials suitable for use in highly sensitive diagnostics of diseases, including various types of cancer. Their article was recently published in the scientific journal Nature Communications.
The simple transport of medicines directly into cells is one of the primary goals of the pharmaceutical industry. In large part, we still don’t possess a detailed understanding at the molecular level of the processes responsible for transporting substances into and out of cells. In collaboration with colleagues from the Czech Republic and Germany, the research team of Pavel Jungwirth from the Institute of Organic Chemistry and Biochemistry of the Czech Academy of Sciences (IOCB Prague) has discovered a previously unknown mechanism by which short peptides are able to penetrate cells and, in principle, could serve as carriers of medicine molecules.
Destructive cyclones are moving to new areas. This is the conclusion of a new study which documents a long-term shift of the zones affected by tropical cyclones. The study was presented by an international team of scientists under the lead of Jan Altman from the Institute of Botany of the CAS in the prestigious journal PNAS, published by the United States National Academy of Sciences.
A unique electron detector, presented half a year ago in Brno, has accomplished its first major discovery. Thanks to the detector, the team in Brno was able to view rotifers from the Brachionus calyciflorus species complex in their natural wet environment, gaining the worldwide primacy in this respect. What’s more, the detector has also helped the scientists discover several hitherto unknown species of these tiny organisms, invisible to the naked eye.
On October 25, CAS President Eva Zažímalová signed the first research collaboration agreement with an American research institution: the University of Memphis.
Leading scientists representing more than 75 European plant and life sciences research centers and institutes have endorsed a position paper that urgently calls upon European policy makers to safeguard innovation in plant science and agriculture. The scientists are deeply concerned about a recent European Court of Justice ruling around modern genome editing techniques that could lead to a de facto ban of innovative crop breeding. As a result, European farmers might be deprived of a new generation of more climate resilient and more nutritious crop varieties that are urgently needed to respond to current ecological and societal challenges.
Spread of dust in atmosphere brings about many risks, including dangers to health or nature. These risks often depend on composition of dust in a given location. Scientists from the Institute of Rock Structure and Mechanics and the Institute of Geology have, therefore, created an electronic Atlas of Dust Particles, the first application focused on information on individual components of atmospheric dust.
Three institutes of the Czech Academy of Sciences join efforts with a faculty of Charles University in creation of Karel Čapek Center for Values in Science and Technology. This new interdisciplinary platform was introduced by Eva Zažímalová, the president of the CAS herself.
In collaboration with their Swedish colleagues, scientists from the Czech city of Olomouc have developed an unusually efficient method which allows for measuring a record-breaking number of 101 plant hormones (phytohormones) and related compounds in a small sample of root or stalk. This method will lead to a better understanding of how levels of hormones change under unfavourable circumstances such as drought or freezing temperatures, thus allowing for a better exploration of mechanisms which help plants to survive.
The world has another meteorite “with pedigree,” i.e. a meteorite with known pre-impact trajectory in the Solar System. It has been unofficially called Renchen because four fragments of this object were found near Renchen, Germany, thanks to Czech calculations. The scenario of this meteorite’s fall, leading to findings of the fragments, was determined by the scientists of the Interplanetary Matter Department of the Astronomical Institute of the CAS through the analysis of data recorded by instruments in Czech, German, and French part of the European Fireball Network, a long-term international experiment started more than half a century ago by Doctor Zdeněk Ceplecha.
