Megafloods in Europe can be anticipated from observations in hydrologically similar catchments
Megafloods that far exceed previously observed records often take citizens and experts by surprise, resulting in extremely severe damage and loss of life. Existing methods based on local and regional information rarely go beyond national borders and cannot predict these floods well because of limited data on megafloods, and because flood generation processes of extremes differ from those of smaller, more frequently observed events. Here we analyse river discharge observations from over 8,000 gauging stations across Europe and show that recent megafloods could have been anticipated from those previously observed in other places in Europe. Almost all observed megafloods (95.5%) fall within the envelope values estimated from previous floods in other similar places on the continent, implying that local surprises are not surprising at the continental scale. This holds also for older events, indicating that megafloods have not changed much in time relative to their spatial variability. The underlying concept of the study is that catchments with similar flood generation processes produce similar outliers. It is thus essential to transcend national boundaries and learn from other places across the continent to avoid surprises and save lives
Function of Tudor Protein in Germline Stem Cells and Brain Development
The medical field has made great strides due to extensive research in biology. More specifically, stem cell biology has provided a new approach to treating complicated medical ailments. Understanding the stem cell components will provide the medical field with the tools they need to better utilize their abilities for treatment. A well-known issue that comes with aging is the degeneration of the neurological system; for example, Parkinson’s disease. Our main research focused on the germline stem cell scaffolding component, the Tudor protein, which has also been demonstrated to be expressed in the brain. Germline stem cells give rise to the sperm and egg, which ultimately produce all cells of the new organism. We worked on characterizing new interacting partners of Tudor and have shown that they are crucial for germline development. In addition, we tested the hypothesis that Tudor and its partners play a role in brain development and memory formation
