Although less visible than shoots, leaves and flowers, plant roots are critical to our lives. They provide the crops we eat with water, nutrients, a firm anchor and a place to store food. Roots are complex branching organs and show a wide variation in the way they grow through the soil to exploit the available resources. The way that new lateral roots are formed and grow is key to this process. Lateral roots originate deep within the parent root and must emerge through intervening layers of tissues before entering the soil. Despite its importance to the integrity and architecture of the root system, little is known about the regulation of lateral root emergence. This question has fascinated, yet frustrated, scientists since the nineteenth century. A paper appearing in Nature Cell Biology reveals for the very first time how lateral root emergence is achieved. It reports that new lateral roots reprogramme the cells that overlay them, causing them to separate and enabling the new root to emerge. In short, the scientists have discovered how new roots open the door to the world outside.

Online registration and abstract submission is now open. My intention for the conference is twofold, to provide a meeting ground for thermodynamicists from all of Europe and surroundings, and to show that thermodynamics is far from being a complete polished subject, useful only as a tool to evaluate chemical and thermal processes. On the contrary, thermodynamics is vibrant with new ideas and methods, receiving inspiration from other fields of science as well as providing inspiration to such other fields, e.g. general optimization theory, fluid dynamics, and ecological modeling. All kinds of thermodynamics are welcome at the conference. The Ilya Prigogine Prize in Thermodynamics will be bestowed on a promising young researcher in thermodynamics for his/her Ph.D. dissertation for the fifth time during this conference. Please help attract good candidates for this very select prize by nominating your very best recent Ph.D. The deadline is 14 February 2009. Details may be found on the conference website. If this entices you, please register to attend the meeting and submit an abstract of your newest discoveries on the conference website [1]www.jetc10.fys.ku.dk Deadline is 14 February 2009. I hope to see you this summer for an inspiring conference and a festive celebration of midsummer. -Bjarne Andresen References 1. http://www.jetc10.fys.ku.dk/
