1.2 Nucleic acids: genetic, functional and structural roles in the cell

The first role that one immediately thinks about for nucleic acids is that of an inherited genetic material, principally in the form of DNA. In some cases, the inherited genetic material is RNA instead of DNA. For example, almost 60% of all characterised viruses have RNA genomes and these are more common in plant viruses than in animal viruses. There is considerable variation in the amount of genetic material present within organisms (Author(s): The Open University

Risk, Uncertainty & The Future of National Security
Officially we are still fighting a "War on Terror", but few people in Australia would say we are still living in an "Age of Terror". Oil prices have quadrupled, but we have not seen the same panicked queuing at petrol stations as when this last occurred. This lecture launches an important new book, Uncertainty and Risk: Multidisciplinary Perspectives , by discussing how risk and uncertainty inform the democratic politics of national security; and more specifically, how the management of national

Changes in microstructure of a shape memory alloy (bi-crystal of austenitic CuAlNi )
Changes in microstructure of a shape memory alloy being heat treated and also mechanically deformed. A bi-crystal of austenitic CuAlNi is cooled, causing transformation to the martensitic (2H orthorhombic) phase. The process is reversed in the second half of the video, as the specimen is heated again. The rate at which transformation occurs is controlled by heat flow effects. (The shear process itself tends to take place very rapidly.) The martensitic phase is internally twinned. This is very cl

This panel will debate the advantages and perils of this changing cultural landscape of state and private support. James Lingwood is co-dire
