Interface Biology of Implants May 6th-8th 2015

I have been attending this since its first instalment, and it has never disappointed - Prof. Rychly (University of Rostock, Germany) always brings together an excellent set of speakers that enthuse the audience of about 140. Very interactive single session style meeting with an intense poster and a good exhibition. This together with the seaside in Warnemünde makes for an unforgettable meeting, every time.

Short meeting summary (we left Friday 2pm):

We Ricky, Monica and myself really enjoyed our time at the meeting, all talks relevant to our work, an enthusiastic and welcoming audience that interacted with the speakers - good questions, and interesting discussions during the lunch/coffee breaks. Poster session very well visited and the presenters sometimes faced challenging but always friendly and interactive discussions. Interestingly two talks offered new hypothesis Alexander Bershadsky explained his and Tom Shemesh's model on how the molecular structure of mDia and F-actin could lead to the dynamic instabilities that were observed when the cells cytoskeleton organises itself whilst they sit on a perfectly round patch. The other hypothesis was put forward by Peter Frazl who offered an explanation on how tension could be built up in collagen by the secretion of hygroscopic molecules such as aggrcan; their local presence in the extracellular reduces the water tension in the collagen molecule, 'drying it out' a little bit. This reduction in water content of the collagen molecule leads to a change in tension, which can be observed in XRD. Other parts of note were the last talk by Marcus Textor, and a brief review of the scientific life of Joachim Rychly by James Kirkpatrick.

Good exhibition - for me interesting were the new "stick on microfluidics" kits from Ibidi, and a new machine to test nanomechanics of cells and materials (need to get the name...).
Evening out at the conference dinner on a boat up and down the Warne and cruising Rostock harbour, fish, fish, and more local specialties as well as wine and local beer. Very interactive and  interesting discussions about all science, and well beyond.
