Denmark’s Statens Serum Institute (SSI) celebrated its centenary last week with an international symposium entitled ‘Vaccines for the 21st century – development and strategies’ (11-12 September), and the launch of a new website (http://www.ssi.dk/) (1). SSI was inaugurated on 9 September 1902 to ensure the production and supply of anti-diphtheria serum for Danish patients. Throughout its 100 year history, the institute has continuously applied research based knowledge to the prevention and control of infectious diseases and congenital disorders.

And Control

Polystyrene (PS) is one of the major plastics contributing to environmental pollution with its durability and resistance to natural biodegradation. Recent research showed that mealworms (Tenebrio molitor) and superworms (Zophobas morio) are naturally able to consume PS as a carbon food source and degrade them without observable toxic effects. In this study, we explored the effects of possible food additives and use of worm frass as potential plant fertilizers. We found that small amounts of sucrose and bran increased PS consumption and that the worm frass alone could support dragon fruit cacti (Hylocereus undatus) growth, with superworm frass in particular, supporting better growth and rooting than mealworm frass and control media over a fortnight. As known fish and poultry feed, these findings present worms as a natural solution to simultaneously tackle both the global plastic problem and urban farming issue in a zero-waste sustainable bioremediation cycle.

Global Growth

Energy forms and their extensive scale are remarkably significant for the ways that societies are organized. This article shows the importance of how societies are ‘energized’ and especially the global growth of ‘fossil fuel societies’. Much social thought remains oblivious to the energy revolution realized over the past two to three centuries which set the ‘West’ onto a distinct trajectory. Energy is troubling for social thought because different energy systems with their ‘lock-ins’ are not subject to simple human intervention and control. Analyses are provided here of different fossil fuel societies, of coal and oil, with the latter enabling the liquid, mobilized 20th century. Consideration is paid to the possibilities of reducing fossil fuel dependence but it is shown how unlikely such a ‘powering down’ will be. The author demonstrates how energy is a massive problem for social theory and for 21st-century societies. Developing post-carbon theory and especially practice is far away but is especially urgent.

And Control

This is an attempt to rethink, ultimately forethink, leadership as a collaborative process of writing and what we think leadership might look like in the 21st century. We try to move beyond leadership taking into account complex relations that shape emergent processes of organizing and change. It is a move away from ideas of individual agency and control. Traditional concepts of hierarchy, selective application, linearity and rationality are no longer appropriate. We offer different shades and elaborations. None are complete or finished. The authority of the reader and audience is pivotal. Through multiple engagements with writing we hope to offer glimpses of powerful leadership.

Game Changer

No other element impacted the historical conditions of the preceding 100 years to such an extent as the war to secure and control the world's reserves of petroleum. Sustainable economic growth after 1873, that discouraged British Empire, arose mechanical economies in Europe. Central Asia remained the object of rivalries and machination by the giant countries of the Europe. World Domination Games started from Pillage Games that lead towards many “Games” such as Great Game, New Great Game, Game Changer and New Game Changer. All prefect countries desire to have a control over the world for the last two centuries. Their efforts turn into numerous clashes and clashes led towards wars. In the twentieth century wars transformed not only their names but also their genetics that has profound impact on the 21st Century. This laid foundation of the emerging new superpowers in every century.
