Ten years of monitoring dissolved inorganic nitrogen in runoff from sugarcane informs development of a modelling algorithm to prioritise organic and inorganic nutrient management.

Reducing nitrogen (N) losses from cropping systems to aquatic ecosystems is a global priority. In Australia, N losses from sugarcane production in catchments adjacent to the Great Barrier Reef (GBR) are threatening the health of this World Heritage-listed coral reef ecosystem. N losses from sugarcane can be reduced by improving fertiliser management.

Farming and the geography of nutrient production for human use: a transdisciplinary analysis.

Background: Information about the global structure of agriculture and nutrient production and its diversity is essential to improve present understanding of national food production patterns, agricultural livelihoods, and food chains, and their linkages to land use and their associated ecosystems services. Here we provide a plausible breakdown of global agricultural and nutrient production by farm size, and also study the associations between farm size, agricultural diversity, and nutrient production. This analysis is crucial to design interventions that might be appropriately targeted to promote healthy diets and ecosystems in the face of population growth, urbanisation, and climate change.

Increased levels of the translation initiation factor eIF4E in differentiating epithelial lung tumor cell lines.

Rates of eukaryotic protein synthesis and proliferation are dependent upon the availability of eIF4F, the cap-binding translation initiation complex that guides the ribosome onto the mRNA. One possible rate-limiting factor in eIF4F complex formation is the availability of eIF4E, which interacts specifically with the mRNA cap structure. As such, it has a potential role in the selective translation of growth-related mRNAs, with overexpression of eIF4E resulting in aberrant cell growth and transformation.
