26. Diversity and Ecosystem Functioning : Redundancy and Resilience in Freshwater Bacterial Communities
Abstract : Bacteria are immensely diverse and hold key-positions in essentially all biogeochemical cycles. In freshwater ecosystems, bacteria degrade and mineralize organic compounds, linking the pool of dissolved organic matter to higher trophic levels. READ MORE

27. Bacterial DNA repair and molecular search
Abstract : Surveillance and repair of DNA damage is necessary in all kinds of life. Different types of DNA damage require different repair mechanisms, but these mechanisms are often similar in all domains of life. The most serious type of damage, double stranded DNA breaks, are for example repaired in conceptually similar ways in both bacteria and eukaryotes. READ MORE

28. Too close for comfort : The role of Contact-Dependent growth Inhibition (CDI) in interbacterial competition and cooperation
Abstract : Contact-Dependent growth inhibition (CDI) was discovered in 2005 in the E. coli isolate EC93. Since then our knowledge of CDI systems and their impact on bacterial communities have increased exponentially. READ MORE

29. A small amoeba at the crossroads of the big RNAi world : MicroRNA biogenesis and Argonaute function in Dictyostelium discoideum
Abstract : Small non-coding RNA (ncRNA) mediated gene silencing, known as RNAi, is a key regulatory mechanism of gene expression in eukaryotes. MicroRNAs (miRNA), one major type of small ncRNAs, are about 21nt long and bound by Argonaute proteins. READ MORE

30. Systemic RNAi Relies on the Endomembrane System in Caenorhabditis elegans
Abstract : The membrane system of a eukaryotic cell is a large and complex system handling the transport, exchange and degradation of many kinds of material. Recent research shows that double-stranded RNA (dsRNA) mediated gene silencing (RNA interference) is a membrane related process. READ MORE
