A Witness of an Ancient Catastrophe Lies Beneath the Aegean Sea

Scientists have discovered a 200-meter-thick layer of volcanic ash in marine sediments near the Cyclades Islands in Greece. This “megabed” was formed 161,000 years ago after a massive eruption on Kos, when pyroclastic currents crossed the shoreline and transformed into submarine density currents that transported ash hundreds of kilometers away. The international team of geologists included Günther Kletetschka from the Faculty of Science, Charles University, and the University of Alaska Fairbanks.

Laboratory mice are often considered the scientific equivalent of identical twins – genetically identical and expected to look and behave the same. But new research from the Faculty of Science, Charles University, shows that this assumption doesn’t always hold true. The team discovered that the composition of the gut microbiota can dramatically influence the structure and function of the immune system – even in genetically identical animals. The study was published in the prestigious journal Gut Microbes.

At this year’s 57th International Chemistry Olympiad (IChO), held in the United Arab Emirates with a record participation of 90 countries and 354 contestants, the Czech team achieved extraordinary success. The representatives brought home one gold, two silver, and one bronze medal from this prestigious competition—marking the best result in the history of the IChO for the independent Czech Republic. Our faculty once again took part in the preparation of the national team, hosting an intensive practical training camp at the Department of Analytical Chemistry. Shortly before their departure, the students also participated in a joint training camp for the Chemistry and Biology Olympiads in Běstvina, organized in collaboration between the University of Chemistry and Technology and our faculty.
