Across many decision-making tasks, people and animals systematically repeat (or alternate) their choices - even when the choices they make are intrinsically uncorrelated. This phenomenon (also known as 'sequential effect' or 'choice hysteresis') has been known for at least a century, and may be a stable…

Stars and planets form within cold, dense clouds of gas and dust drifting through interstellar space. Although dust makes up only a small fraction of this material, it plays a key role in shaping the chemical evolution of these environments.

This thesis explores how electron paramagnetic resonance (EPR) spectroscopy can be used to investigate key biochemical processes.

Effective policy-making requires understanding what truly causes a problem. Only then can policymakers develop targeted interventions that achieve desired outcomes.

The sixth issue of Ex Novo explores how ‘peripheral’ regions currently approach both the practice and theory of public archaeology placing particular emphasis on usually underrepresented regions of Eastern and Central Europe, the Mediterranean and beyond.

Farmers do not love them all. Microbes can cause tragic consequences for crops. Even the presence of just one pathogenic fungus or bacterium can drastically reduce yields. Still, there are exceptions. In that case, a pathogenic microbe is present in the soil, but does not cause any harm. Adam Ossowicki…

A specifically designed collection of gears is soft on one end and rigid on the other. These are robust properties of the system that hold even in the presence of manufacturing imperfections. This emerging research area may lead to new ways of designing geared devices like satellite trackers or watches.…
