The UN General Assembly has declared 2015 the International Year of Soils to raise awareness of the vital importance of soil, which is essential not only for food security and for cultivating plants for feed, fibre, fuel and medicinal products, but also for maintaining biodiversity as it hosts countless organisms. It plays a key role in storing and filtering water, in carbon and other nutrients cycling and performs other irreplaceable ecosystem functions. The Institute of Soil Biology of the CAS Biology Centre carries out biological research into many of those functions of soil in both natural and human–affected environments, including studies of the soil microstructure, soil organism communities and their dynamics and interactions and so on. Researchers at the Institute of Soil Biology focus, among other things, on the contribution of soil fungi to nitrous oxide emissions and on the production of methane. The latter is a potent greenhouse gas and a substantial part of atmospheric methane is produced by anaerobic microorganisms called Archaea found in the soil and in animal digestive tracts, while soil is also a significant methane sink. Research is also being concentrated on the characterization and risk assessment of antibiotic resistance-reservoirs in soil, which is connected with the massive use of antibiotics in the past five decades. Scientists examine ways of preventing the antibiotic resistance spreading in the environment through food chains as well as and on the role played by the soil microflora in those processes, as Doctor Dana Elhottová explains in the corresponding article. and Jana Olivová.
We present an interview with Robert lzzard whose doctorate is from Cambridge University and who has been awarded an Intra-European Fellowship for Career Development which is a part of Marie Curie Actions. His research at l'Universite Libre de Bruxelles is focused on the evolution of binary stars. and Andrea Khudhurová.
We feature an interview with Professor Eva Za2imalova, a member of the Academy Council and the head of the Laboratory of Hormonal Regulation in Plants at the Institute of Experimental Botany of the ASCR. From 2007 to 2012 she was director of this institute. Her research is in the fields of auxin and cytokinins (mode of action of auxin. auxin binding site(s), regulation of levels of auxins and cytokinins in relation to cell division and elongation and themechanism of polar transport of auxin). and Marina Hužvárová.
The European Union has allocated 31 million crowns for the professional enhancement of Czech scientists and international activities of research teams at the Institute of Scientific Instruments of the ASCR and the Faculty of Electrical Engineering and Communication of the University of Technology in Brno. The EU subsidy encompasses three years. Thanks to this financial support, Vladislav Krzyžánek, a leading Czech expert in electron microscopy, has returned to Brno after 12 years in Muenster, Germany. The EU subsidy will additionally fund training workshops, guest stays of foreign scientists, support for researchers’ mobility and the establishment of cooperation between universities and the industrial sector. and Luděk Svoboda.
Proč se nekříží kočka se psem? Proč se sice může zkřížit kůň s oslem, ale jejich potomci - mulové či mezci - jsou neplodní? Z jakého důvodu jsou někdy strilní i kříženci dvou blízce příbuzných poddruhů, třeba myší, a souvisí to nějak se vznikem nových živočišných druhů? Jeden z nejdůležitějších článků tété záhady odhalil Jiří Forejt z Ústavu molekulární genetiky Akademie věd ČR, kterýá identifikoval první gen u savců zodpovědný za samčí neplodnost mezidruhových kříženců, přečetl ho a ukázal, jak je regulován. and Jana Olivová, Stanislava Kyselová.
