It is well documented that the space of informal economic activity is rising across the globe. This rise has been particularly significant in the least developed and developing countries, especially after the onset of neo-liberal policies and withdrawal of welfare state. There has also been a shift in academic thinking on informal sector, with attempts being made to understand the contribution of informal sector in generating employment and economic growth rather than focusing solely on exploitative labour conditions in these economic activities.
- Using nanotechnology, scientists can change the atomic configuration of matter. New materials have seemingly magical applications, with promise that ranges from harnessing energy from the sun to eternally recycling materials by breaking them down into their atomic building blocks and reassembling them. It is vital, as UNESCO has urged, that social scientists engage fully in debates on nanoethics, and contribute to policy and decision-making processes concerning the use of nanotechnology in achieving sustainability.
