  • When will the oil run out? Various estimates put this anywhere from 20 years from now to more than a century in the future. The shortfall in energy might eventually be made up by developments in nuclear fusion, fuel cells, and solar technologies, but what can substitute for gasoline and diesel in all the internal combustion enginepowered vehicles that will continue to be built worldwide until then? And what will stand in for petrochemicals as sources of building blocks for the extensive range of “synthetics” that became indispensable during the twentieth century?...

  • With shortages of fossil energy and heavy biomass energy use occurring in both developed and developing countries, a major focus has developed worldwide on renewable energy systems. Currently, a heavy focus is on biofuels made from crops, crop residues and wood. Though it may seem beneficial to use renewable plant materials for biofuel, their use raises many concerns about major environmental problems, including food shortages and serious destruction of vital soil resources.

  • In consultation with many local organisations and groups the Environment Agency has produced Catchment Flood Management Plans (CFMPs) covering the main 68 catchments in England. These documents set out the strategic context for managing flood risk in a catchment, helping decision makers by identifying the policy options being adopted to manage flood risks. They also help form the position we take in our work to manage assets, watercourses, flood forecasting, and to help land use planning and development.

  • What is intuition? It is important for me to mention that intuition is always present. Accessing our intuition provides a way for us to take in, and be aware of, our sensory guidance by embracing our sensitivities. As we develop our ability to tune in and connect with these subtle energies, we develop a most wonderful and useful skill.

  • An outstanding feature of the lower Mekong region is the dynamic energy of its natural systems and how intimately tied most of the population is to that seasonal force. Productivity in agriculture and fisheries, for example, depends on annual floodplain inundation and nutrient dispersal. The immense scale and impact of this natural cycle is well illustrated in the annual flooding of Tonle Sap Lake in Cambodia and the Mekong River Delta which it shares with Vietnam.

  • THE VEGETATIVE PHASE OF DEVELOPMENT begins with embryogenesis, but development continues throughout the life of a plant. Plant developmental biologists are concerned with questions such as, How does a zygote give rise to an embryo, an embryo to a seedling? How do new plant structures arise from preexisting structures? Organs are generated by cell division and expansion, but they are also composed of tissues in which groups of cells have acquired specialized functions, and these tissues are arranged in specific patterns.
