Fantastic WIMPs and Where to Find Them
The overwhelming evidence that the dominant form of matter in the Universe is fundamentally different from any visible matter demonstrates the limitations of our current understanding of particle physics. At the same time, it provides a compelling argument for expecting new physics to be discovered in the near future. In this colloquium, I will review the global effort to search for this so-called dark matter, pursued by a wide range of different experiments. I will argue that solving the dark matter puzzle requires input from many complementary observations and discuss how all this information can be combined using the most recent developments in analysis tools and global fitting frameworks.

Designing novel solar devices via understanding the link between structure, chemistry, and performance at the nanoscale
Solar energy, which is the Earth's major renewable energy resource, is one of the reliable source of "green electricity". The conversion of the sunlight into electricity is done using solar cells. A key parameter which describe the quality of a solar cell is the efficiency (how many percentage of sunlight is converted into electricity). However, the impact of the physical phenomenon taking place at the nanoscale on the efficiency had only been vaguely studied in literature.
Therefore, in this colloquium I will show a possible viable strategy in improving the cell performance first by understanding the limiting factors in terms of electrical, structural, and chemical properties at the nanoscale and second by applying these novel R&D findings in designing better solar devices.

SESAME - a synchrotron radiation laboratory in Jordan and "science for peace"
A dream became reality by the creation of an international laboratory in the MENA region under the auspices of UNESCO following the CERN model with the objectives of promoting science and technology but also bringing nations together. The political, legal and technical pitfalls will be described. Decisions are not taken always on rational grounds but chance and the interventions of some personalities were significant as will be exemplified by some stories. Now government officials and scientists from countries with political frictions work together peacefully. Thus science benefits from politics but also the reverse is true. The facility was inaugurated in May 2017. A user community has been established and first experiments start to work. A new initiative following the SESAME example has been initiated very recently for the Balkan.

New Perspectives in Scientific Publishing
How will scientific publishing develop in the 21st century? Over the last decades topics such as Journal Impact Factor, blind peer-review and library subscriptions have dominated the discussion. However the digital revolution has already begun to change the rules. New topics such as “article- level-metrics”, “post-publication peer review” and “open data” have emerged and every single day four new Open Access journals are founded. Open Access is becoming publicly mandated in the US and EU, encouraging researchers to submit their work to open repositories. Preprint servers and subject repositories such as arXiv or bioRxiv have been entering the market to provide faster access to unpublished results. Open peer review is practiced by ever more journals and consortia. Post- Publication Peer Review is a new buzz word to use crowd-sourcing to evaluate scientific research. Publication of research results is at the center of the scientific enterprise. It is therefore essential not only for young scientists to have a good overview of the changing publishing landscape. This seminar explores the ways in which the speed and network character of the internet breaks down old categories of scholarly publishing and creates new ways of communicating scientific results.
