Combined Colloquium Willi Wilson & Douwe Maat: Thursday 15 December 2016, 14:00
(NIOZ Texel, video broadcasted to NIOZ Yerseke)
Abstract Willi Wilson (email@example.com):
Sir Alister Hardy Foundation for Ocean Sciences (SAHFOS), Plymouth UK.
What did algal viruses do for us anyway (apart from establishing an evolutionary path to eukaryotic life)?
Did you ever go to write an abstract after realising what a crazy title you had offered? OK let me start as I mean to go on: Every day, every moment, an epic battle is raging across the globe. It's happening in the ocean. The evidence is both highly visible and totally hidden, depending on your perspective. In this talk, Willie will discuss the tale of an arms race involving trillions of sea creatures and why their struggle is vital to life on this planet. A group of phytoplankton, known as coccolithophores, are engaged in a surprisingly complicated arms race with deadly giant viruses. A virus is problematic enough when you're a human. Now imagine being a single-cell alga and mixing it up with the hugest virus you've ever seen. The coccolithophores are outgunned, but they won't go down with out a serious fight. The talk will start with a RadioLab interview (previously aired on National Public Radio in the US) by reporter Ari Daniel Shapiro who visited Willie to explain how our itsy-bitsy heroes take arms against a sea of troubles. Their discussion explores how this battle, and others like it, makes life on Earth possible. Willie will continue the dialogue using examples of his research on the coccolithoviruses and development of single-virus genomics approaches to study them and other virus leviathans.
As an added bonus, Willie will introduce the work of the Sir Alister Hardy Foundation for Ocean Science (SAHFOS), an internationally funded independent research organisation responsible for the operation of the Continuous Plankton Recorder (CPR) survey. As a large-scale global survey, it provides the scientific and policy communities with a basin-wide and long-term measure of the ecological health of marine plankton. Established in 1931, the CPR survey is the longest running and most geographically extensive marine ecological survey in the world.

Designing complex microstructures
W. L. Noorduin
Institute of the Foundation for Fundamental Research on Matter (AMOLF), Amsterdam, The Netherlands
Over the course of evolution, organisms have developed a gamut of strategies for controlling nucleation, polymorphism, material composition, shape and hierarchical organization of mineralized components. Although the complexity of these biominerals has fascinated scientists for centuries, the underlying mechanisms often remain poorly understood. Harnessing the basic principles that guide such self-organizing processes is therefore of fundamental scientific interest, but also promises a paradigm shift in the manufacturing of nano- and micromaterials. We recently demonstrated that the subtle balance between the diffusion of reactants and their reaction rates could lead to a wide range of microscopic shapes that could be further sculpted and hierarchically organized by rationally modulating the environmental conditions. Based on fundamental insights in the underlying mechanism, we now present new ways to steer the nucleation and growth of mineralizing microstructures. These results contribute to our understanding of biomineralization processes and outline a new nano-fabrication strategy for functional self-organizing materials.
We look forward to welcoming you all!

There is a large degree of flexibility for our NIOZ colloquia and we will try to accommodate speakers as much as possible. The auditorium has a PC connected to a beamer as well as a video conferencing system, a USB flash drive with the presentation will therefore suffice. However, we can also accommodate laptops, both PC and Mac. We aim for presentations of ca. 30 minutes and no longer than 45 min. We would also like to ask speakers to keep in mind that the colloquia are open to the entire NIOZ and beyond and that not everyone in the audience will be an expert on the presented topic. If there are question please contact colloquium[at]nioz.nl.
