Baseline testosterone in hunter-gatherer societies: Actually not that high.
A recent article by Trumble et al. (2012) investigates testosterone levels in the Tsimane, hunter-gatherer society in the Bolivian Amazon. They organised a competitive football match between eight different Tsimane villages (Seriously, how cool is that – organising a football match as part of your research?), tested testosterone levels of the (male) players men before and after a match and compared these to testosterone levels in an age-matched male US sample. The authors have two key-findings: On the one hand, both groups show increased testosterone levels in a competitive football match. On the other hand, baseline testosterone levels are lower in the Tsimane.

"I am not going to read your diatribe!"
Paul Feyerabend was one of Popper’s earliest students and followers, but soon turned to criticise Popper’s theories vigorously. Neither of them were shy of words when criticising colleagues’ works, nor would they try to conceal their criticism. Feyerabend recalls the following dialogue:
“‘I am not going to read your diatribe!’ Popper had shouted when he saw my [Paul Feyerabend’s – Antipattern] comments on his diatribe against Bohr. (He calmed down when I told him that many people had complained about my aggressive style and had ascribed it to his influence. ‘Is that so?’ he said, smiling, and walked away.)” (in: Feyerabend 1995, p. 146)

The impact of external funding: Deutsche Bank and the Quantitative Products Laboratory
Both, the German daily TAZ and the weekly Der Spiegel report that the Deutsche Bank has financed lectureships and research projects at Berlin universities, and supported the foundation of the Quantitative Products Laboratory, a research institute in applied financial mathematics. This raises questions about the independence of the research carried out at the institute, and the role of external funding in science.

Fear, Faces and the Amygdala
Brain imaging techniques such as CT, fMRI and EEG have revolutionised psychology. They are indeed exciting technologies that can offer insights into the way our brain works. And thus, scientific columns in newspapers regularly report that a behaviour or perception can be linked to a certain brain area. The idea is that if we know that if a brain area is active during a certain task that is otherwise not, it is involved in the process, or, if a brain area is defective and with it specific cognitive functions, then these are linked, too. But things are not as simple. (They never are) Just because an area is active during a cognitive process does not necessarily tell you what it actually does.
