Plant cells inherit knowledge of where’s up and where’s down from mother cell

In plants, polarization of the entire organism depends on every single cell being polarized. Cell division, however, disrupts polarization. How polarity is reestablished was unknown – until now. Researchers at the Institute of Science and Technology Austria (IST Austria) and Faculty of Science, Prague, have solved one piece of the puzzle: They found that plant cells inherit the knowledge of where is up and where’s down from their mother cell. Study published in Nature Plants.

Our Yeast research experts have received a prestigious Czech-American grant under the INTER-EXCELLENCE programme

The Yeast Colony Group team has been awarded grant support from INTER-EXCELLENCE programme for a new project of international research and development aimed at Czech-American collaboration. Supported project focuses on research into the molecular mechanisms of cell adaptation connected with cell aging, one of the most important questions in current biology. Regulatory proteins mediating cellular response to extracellular signals are among the most evolutionary conserved proteins in eukaryotes. Understanding of their function in relatively simple yeast model thus could contribute to identification of new regulations in metazoa.

The prestigious science journal Nature Communications published the revolutionary method of Czech scientists

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 first author of the present study is recent PhD graduate at Faculty of Science Jan Havlik.

Popular Science: The work of anthropologists in commercial archaeology

While excavating human remains in commercial archaeology, anthropologists are often limited by financial and time constraints and the collection of meaningful information is therefore rather difficult. That is why technologies and work methodology need to be quicker, cheaper and simpler and the collaboration between anthropologists, archaeologists and developers needs to be better to achieve maximal results. Erika Průchová from our faculty and her colleagues examined these field techniques and their effectiveness during the recent excavation of three cemeteries in Karlín, Prague.

Popular Science: WHAT CAN WE LEARN ABOUT BIRD-MAMMAL RELATIONSHIPS USING GOOGLE IMAGES?

Citizen science – or the involvement of the public into science research – has become an integral part of research work in many fields. There are thousands of projects anybody can join. In your free time you can record a bird song, classify photos of retina neurons, build a quantum computer in an app game or search for dusty debris disks in NASA’ photos. Another possibility is to make use of a huge amount of data people unconsciously collect – photos and videos of various plants and animals. Such pictures were analyzed by zoologists Peter Mikula, Jiří Hadrava and Tomáš Albrecht from the Faculty of Science of Charles University.

Popular Science: How did the elite and serfs chew in the Great Moravian Empire?

The human body has axial symmetry. However, the symmetry is not perfect; everyone certainly knows the unnatural pictures which result from mirroring half of a human face. Asymmetry is a common fact and occurs even in bones. It may be caused by side preferences, but it may also be a signal of long-term stress during maturation. A relationship between chewing and face asymmetry was studied by a research group led by PhD student Alexandra Ibrová from the Department of Anthropology and Human Genetics who focused on the skeletal material from the age of the Great Moravian Empire.

Popular Science: Cemetery or urban park? Where do birds have more fear?

Have you ever thought that by visiting a cemetery, you are influencing the behavior of its inhabitants? Of course, not those who have passed away, but those still living, like birds for instance. They have to deal with your presence, get used to you walking, talking, working and altering their habitat. Peter Mikula, from the Department of Zoology of the Faculty of Science, was part of an international team that compared the escape behavior of birds in European cemeteries and urban parks in order to determine the birds’ ability to adapt their behavior to different environmental conditions.

Popular Science: Colloquium – Science – Visualisation – Perception

In late June the first one-day gathering about the issues of visualisation in science took place at the Department of Philosophy and History of Science, intended for both a scientific and non-professional audience. The event was organized by the department staff members (Lucie Čermáková, Eliška Fulínová, Tereza Liepoldová and Roman Figura) in collaboration with Barbora Müllerová from the Jan Evangelista Purkyně University in Ústí nad Labem. Filip Jaroš (University of Hradec Králové) and Doc. Karel Stibral (Masaryk University in Brno) also took part in the event.

Popular Science: How did Tycho Brahe (1546-1601) die? Science reveals possible causes of his death after more than 400 years

The death of the famous Danish astronomer Tycho Brahe was sudden and due to the circumstances and symptoms observed in his last days, it was even assumed he might have been poisoned. Previous studies, however, refuted the speculative hypothesis of poisoning and rather suggested an acute illness as a more probable cause of death. In 2010, a second exhumation of Brahe`s body was performed in order to find the answer as to why he died so relatively young, even in his times. The research was conducted in a collaboration of Danish, Czech and English teams, including Professor Jaroslav Brůžek, a PhD. Student of the STARS program Alizé Lacoste-Jeanson from the Department of Anthropology and Human Genetics of the Faculty of Science.
