New evolutionary mechanism for bacterial populations discovered
Mutations and horizontal transfer of genes represent evolutionary mechanisms which have been studied extensively over decades. Until now, the role of horizontally changing gene regulatory elements at the level of population evolution has been unknown. In a study published in PNAS, professor Jukka Corander joined forces with scientists at MIT and Tel Aviv University showed that horizontal rewiring of gene regulatory elements is a ubiquitous mechanisms across different species of bacteria and holds considerable potential for their adaptation to changing environmental conditions.
Long-term evolution of ETEC bacteria unearthed
Enterotoxigenic E. coli (ETEC) bacteria cause annually at least 400 million diarrheal disease cases according to WHO investigations. The ETEC bacteria are a common trouble for travelers and kill approximately 400000 small children per year in the developing countries. According to current knowledge, these bacteria evolve very rapidly such that harmless commensals turn frequently into new ETEC strains via horizontal gene transfer.
HIIT and HSL finalize a large-scale trial on urban mobility
HIIT / University of Helsinki and Helsinki Region Transport (HSL) collaborated in a large-scale trial in October 2014. More than 400 volunteers participated in testing next-generation journey planning tools at Helsinki metropolitan area. These tools included mobile and web-based applications for fully multi-modal journey planning (public, private, and shared transportation modes) with additional features such as gamification to encourage more eco-friendly mobility.
Symbiotic 2014 organised in Helsinki with exciting keynotes
The 3rd International Workhop of Symbiotic Interaction was held in Helsinki chaired by Prof Giulio Jacucci from HIIT. The workshop gathered more than 50 participants from Europe and US and proceedings are published by Springer. The workshop was opened by the greetings of the Ambassador of Italy in Finalnd His Excellency Giorgio Visetti on te 30th of October.
