Babbage: Hollow-grams? Holograms have fallen short of the vivid, floating projections seen in science fiction. However, one scientist is copying an iridescent butterfly to create better effects. Also, how blow flies are helping to solve murder mysteries. And why genetic testing is threatening the insurance industry. Kenneth Cukier hosts.
Collusion elusion: the Mueller report Robert Mueller, the special counsel, has at last delivered his report on President Donald Trump’s campaign. Will it have disappointed or empowered the Democrats in Congress who are still bent on investigating the president? And, four years ago the hard-left Syriza party stormed to power in Greece. But it has broken many of its campaign promises. As an early election looms, we take a look at Syriza’s slow slide.

Keep on learning There are more than 800 courses on OpenLearn for you to choose from o Base pairing Nucleic acid folding patterns are dominated by base pairing, which results from the formation of hydrogen bonds between pairs of nucleotides. In nucleic acids, as in proteins, the highly directional nature of this hydrogen bonding is the key to secondary structure. 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): 7.5 Control measures There are four main methods of exposure to chemicals: Inhalation – This is the main method of exposure to volatile solvents and gases. Skin absorption – Certain chemicals possess the ability to penetrate through pores of skin (for example, mercury compounds and hydrofluor References Keep on learning   There are more than 800 courses on OpenLearn for you to Conclusion This free course provided an introduction to studying Science. It took you through a series of exercises designed to develop your approach to study and learning at a distance and helped to improve your confidence as an independent learner. 6.1 Basic isotropy As we have said, the photons in the 3 K background have been practically free from interaction with anything since about 4 × 105 years after the instant of the big bang. The present angular distribution of the microwave radiation – the way in which it is spread across the sky – is therefore almost the same as it was then. The spectrum we find today depends on the temperatures at that time – for the intensity of the radiation in a particular region of the early Unive 1.2.6 Defining global markets Global markets for manufactured goods, as opposed to, say, primary commodities such as oil and timber, arose largely in the second half of the twentieth century as trade between countries intensified. The lowering of transport costs and the relative fall in trade barriers enabled firms in one country to compete with a domestic rival in another. The supply of manufactured goods across the globe as a result of worldwide demand, principally from the affluent economies, thus heightened competitio
