10.7 The media and public understanding of climate change

Hargreaves, I., Lewis, J. and Speers, T. ‘Towards a better map: Science, the public and the media’, Economic and Social Research Council.

Our analysis of media coverage suggested that this was an issue that received more attention in the broadsheets than the tabloids, with The Guardian and The Sun/News of the World being at the two ends of the spectrum. It is notable, then, that in the October Survey 83 per cent of Guardian/Independent readers felt that c

Advances in Nanotechnology
 In this podcast, Professor Moriarty discusses nanotechnology, and how it has led to a convergence of the traditional sciences. He talks about the commercial applications of nanotechnology such as hard disk technology in laptops, stain free materials and fabrics, self-cleaning windows and advanced water filtration.

He also touches on some of the myths about nanotechnology as well as some of the real dangers of Nanotechnology and the steps governments are taking to regulate it.

Solid State Physics
In the electrical engineering, solid-state materials and the properties play an essential role. A thorough understanding of the physics of metals, insulators and semiconductor materials is essential for designing new electronic devices and circuits. After short introduction of the IC fabrication process, the course starts with the crystallography. This will be followed by the basic principle of the quantum mechanics, the sold-state physics, band-structure and the relation with electrical propert

Using A Simulated Student for Instructional Design
In this paper, I describe how a cognitive model was used as a simulated student to help design lessons for training circuit board assemblers. The model was built in the Soar cognitive architecture, and was initially endowed with only an ability to learn instructions and prerequisite knowledge for the task. Five lessons, and a total of 81 instructions for teaching expert assembly were developed by iteratively drafting and testing instructions with the simulated student. The resulting instructions

1.1 Early observations

Some of the earliest observations of macromolecules within living cells were of nucleic acids in the form of chromosomes. These long dark-staining objects, which became visible in the nucleus of cells at specific stages of cell division, were large enough to be detected using primitive light microscopes. Giant polytene chromosomes, found in certain cells such as the salivary gland cells of Drosophila (see Figure 1a), contain many thousands of copies of each chromosomal DNA align
