Tyler Thrasher is an artist using many different techniques to express himself. He is a musician, a painter, an illustrator, a photographer and, not least, to some extent a scientist. For one of his current projects, he grows crystal clusters on collected, inanimate objects, like dead insects and skulls. By transforming deceased creatures into something beautiful, often mystical, he attempts to follow the approach of alchemists. Nevertheless, his art builds on “hard science” and follows the physical rules of crystallization. His results offer a different, inspiring view on a well-known method and teach not only science but also the inherent beauty of their studied objects.

Physicist or Comedian? Action or science? Science journalist Dr. Sascha Ott provides during his talks and shows impressive evidence that knowledge and humor do not necessarily have to be contrasts.

Dr. Ott started studying physics in 1991, but soon figured out that journalism appeared to be more attractive to him. Eventually, he became a profound science journalist and started to perform his own science talks and shows.

Eine Stichprobengroesse von N = 1, da straeubt sich der Wissenschaftsjournalist. Aber da das N in diesem Fall nicht N. N., also noch zu benennen ist, sondern mir bekannt, weil ich es selbst bin, berichte ich heute ueber einen kleinen Selbstversuch im Hirnscanner. Ich habe mich zweimal in die Roehre gelegt, vor und nach dem Sommer. Dazwischen habe ich Tanzstunden genommen. Ich wollte wissen: Wie plastisch ist mein Gehirn?

The continuous growth in human population implicates an increasing need for water. This demand encloses especially industrial structures. The federal state Pernambuco is one of the leading textile producers in Brazil. Although, the dry sub-humid state represents less than 5% of its national population, it covers approximately 20% of nationally manufactured jeans. Its high water consumption exacerbates the environmental situation during the actual strong drought which continues to impact the entire

northern part of the South American continent. One main factor is the emission of chemically contaminated effluents from industrial laundries to Ipojuca river, being the third most contaminated river in Brazil. In this study, we analyse impact factors contributing to anthropogenic environmental damage in one of Pernambuco’s main jeans producing region, Caruaru, and provide a sustainable solution towards waste water treatment. The methodology encloses a comparison of the exemplary sewage water management in the city Hof, Germany. Our results enclose parameters responsible for the damage to the fragile environment in Pernambuco and the Ipojuca River as well as a model for a sustainable infrastructure of the intended expansion of the industrial park in Caruaru.

PD Dr. Nicolai Bissantz is a mathematician at the Ruhr University Bochum, Germany. His research fields are applied and mathematical statistics, in particular with applications in science and engineering. Amongst these fields are applications of statistical inverse problems in astronomy and in image reconstruction. Such problems arise e.g., in the recovery of images from fluorescence microscopy imaging and in medical imaging devices such as PET (positron emission tomography).

Dr. Rainer Wanke is a physicist working in the field of experimental particle physics at the University of Mainz, Germany. He is working on the NA62 experiment at the European Organization for Nuclear Research (CERN) in Geneva, Switzerland, which measures ultra-rare K-meson decays. This involves both, particle detector development and the analysis of data taken with those particle detectors. He furthermore teaches statistics for undergraduate students in Mainz.

A Commentary on “Most People are not WEIRD” by Joseph Henrich et al., Nature (2010)

Prof. Joseph Henrich is an anthropologist at the Department of Human Evolutionary Biology at Harvard University, Cambridge, USA. His focus is on evolutionary approaches to psychology, decision-making and culture. Together with his colleagues Stephen J. Heine and Ara Norenzayan at the University of British Columbia, Vancouver, CA, he was the first to point out that, in economics, psychology and cognitive science, conclusions are generally drawn from study participants with the same background: Western, Educated, Industrialized, Rich and Democratic (WEIRD). In addition, primarily students form the majority of test subjects. Still, researchers – often unintentionally – claim that their findings apply to everybody.

Open access sharing contributes nowadays a major part to the publication process in many different scientific disciplines. One could think it is an invention of modern time, however, the idea to make data and literature widely available is quite old: Libraries.
