The International Society for Extremophiles and the Italian Society of Astrobiology are pleased to announce the 12th International Congress on Extremophiles (Extremophiles2018) that will be held from September 16-20, 2018 in Ischia (Naples, Italy). In the tradition of these meetings, Extremophiles2018, in the volcanic island of Ischia, aims to showcase state-of-the-art research on basic and applied aspects of life in extreme environments and to stimulate high quality research, inspiring those already working in the field and young scientists approaching extremophiles. The Conference will include sessions on many aspects of research related to extremophiles, including origin of life, ecology, astrobiology, molecular biology, physiology, and biotechnology. As part of a NASA supported TWSC grant, there are a number of travel grants available to US-based scientists for attending the conference. Interested Graduate Students, Postdocs and Early Career Faculty (within 5 years from their appointment) with interest in Extremophiles and Astrobiology are encouraged to apply. The deadline to apply for the travel grant is June 20, 2018.
