Physicists seek animated answers to dark secrets of the universe
Nov. 29 - Physicists at the Argonne National Laboratory in Illinois hope to unravel the mysteries of dark matter and dark energy with the most detailed computer simulations of the universe ever built. The two theoretical forces have never been detected but are believed to make up more than 95 percent of the universe The researchers want to know what the forces are and how they work. Ben Gruber reports.

Introduction This course explores origins of the Universe by looking in detail at events immediately following the Big Bang. Starting with looking at the cooling of the very early Universe, the course then moves on to the inflation era, the quark-lepton and the hadron era. Then the course looks at how fundamental particles began to synthesise to form nuclei, and from here it discusses the development of larger structures like stars and galaxies. By examining closely the forces in play and the interactions
Test kits for water analysis
This free course, Test kits for water analysis, steps outside the laboratory to look at some examples of analytical procedures being carried out in the field using commercial test kits. These quick tests provide results on-site, extending the options available to analysts. The methods used are chemical or microbiological in nature, made portable by microelectronics.Author(s):

4 Summary of video At the beginning of the video clip, Dr Simon Campbell pointed out that, in the development of any drug, there are a number of criteria that must be satisfied. There must be a clinical need – a medical condition or disease that requires effective treatment. Secondly, there has to be a commercial opportunity; because drug development is so expensive, pharmaceutical companies are less likely to invest resources in developing new therapeutic agents where there is already an adequate range of su
2 Video activity The video clip included in this section looks at the development of one particular drug. It examines the complex multidisciplinary process that was involved in its discovery. Before you watch the video, read through the Pre-viewing notes. 2.14 Summing up Dr. Peterson concludes the audio sequence with a summary of all the points covered. 2.9 Conflicting morphological characters This clip looks at conflicting morphological characters and at how it is possible to resolve them, with the aid of a table of molecular characters (Figure 9).
