4.2 The functional group approach
What causes pain and how do we stop it? This unit looks at how the human body responds to the release of certain chemicals and as a result feels pain. Pain can be reduced by inhibiting the formation of such chemicals and you will learn how the molecular structure of aspirin has been formulated to help in this process.
1.3.3 Stage 1: Preparation The task here is very different from our task when faced with numbers, where we need to deal with a high level of abstraction. Writing is often dense and multi-layered, and usually gives us, if anything, too much surface information about our subject. We need to make a mental effort this time in selecting and abstracting information ourselves. In order to do this effectively we need to be aware of the context of the writing. We need to check if we can, for instance, the political and s

William Wilberforce, the politician and religious writer, was instrumental in the abolition of slavery in Britain in 1807. This unit explores Wilberforce’s career and writings and assesses their historical significance. In particular it examines the contribution that Evangelicalism, the religious tradition to which Wilberforce belonged, made in the transitions between the Enlightenment and Romanticism. Throughout it relates Wilberforce’s career and writings to wider social and cultural devel

Thailand in Crisis- Episode 4
Professor Thongchai Winichakul is the special guest for the fourth Thailand in Crisis vodcast. With host NIcholas Farrelly, he discusses the 1976 protests, his time in detention, his reaction to the recent crackdown on the Red Shirt protests and his hopes for the future of Thailand. Farrelly is also joined by Andrew Walker to discuss Thai government investment into agriculture. Thailand in Crisis is a series of six vod and podcasts from The Australian National University's College of Asia and th
Darwin’s Compass: Why the evolution of humans is inevitable
Orthodox neo-Darwinism very much emphasises the random and contingent. Re-run the tape of life, as Steven Jay Gould famously observed, and the outcomes would be utterly different. Terrestrial life maybe, but certainly no humans. They, like tulips and tape-worms, are just another evolutionary fluke. The basis of this is hardly surprising: think of random mutations, massive shifts in the environment, not to mention the odd giant rock dropping out of the sky. Life is on a roller-coaster and is flun
Seduced by DNA: From Chromosomes to Cancer
In this lecture, Professor Cory will give a personal perspective on her
career, covering how she came to become a molecular biologist and how
her fascination with chromosomes led her into cancer research and the
quest to develop better cancer drugs.
This lecture was sponsored by the ANU College of Science as part of their 2006 Dean's Lecture Series.
Cell Fractionation in Tetrahymena
To illustrate cell fractionation, nuclei are isolated from the ciliated protozoan, Tetrahymena thermophila. A table top clinical centrifuge is used for the fractionation steps and the procedure is monitored microscopically using a differential stain. To determine the efficiency of the procedure, cell and nuclear counts are determined with a hemacytometer. To quantify DNA, the Diphenylamine Reaction is carried out and the amount of DNA per nucleus is calculated.
BioGrapher
PURPOSE: A simple Excel-based workbook with worksheets as a front end for the AT&T GraphViz Graph Layout software suite. BioGrapher enhances Excel-based tools developed in the Chemistry and Biology Departments at Beloit College to allow for convenient visualization of graphs and graphical connections that are important
in systems and computational biology, molecular biology, biochemistry, and genetics.
Metal-containing molecules and DNA
PhD student, Adair Richards, and Professor Alison Rodger from the Molecular Organisation and Assembly in Cells Doctoral Training Centre (MOAC) talk about their work and recent article about binding metal-containing molecules to DNA.
Length: 20 minutes
Greenomes
The Greenomes site is part of a laboratory- and Internet-based curriculum to bring college students up to the minute with modern plant research. Plant molecular genetic and genomic research still lags behind medically-oriented research on microbes and higher animals. As a result, there are relatively few lab experiences that expose college-level students to the growing insights into plants offered by genomic biology.
Clean Energy: Converting Light to Energy
This unit explores the issue of energy production as a pressing global issue and how nanoscience could enable important breakthroughs in energy generation and conversion. In particular, traditional and newer "nano" solar technologies are introduced and explored. Upon completing this unit, students will understand: Clean alternative energy technologies must be developed to provide sufficient energy to meet growing global demand, and must be sustainable both environmentally and economically; Nanos
Building Molecular Models of DNA, Protein, and Lipids
Molecular models of DNA, protein (alpha-helix and beta-pleated sheet), and lipids are built to scale. With a minimum of scientific jargon, these laboratory exercises effectively display the important aspects of three-dimensional shape and spatial orientation that are poorly presented in textbook illustrations and demonstrate how the shape of molecules and weak chemical associations like hydrogen bonds and hydrophobic/hydrophilic interactions combine to form the macromolecular associations fundam
An Introduction to DNA: Spectrophotometry, Degradation, and the 'Frankengel' Experiment
In this laboratory students perform three exercises as an introduction to the basics of handling and analyzing DNA. In the first, they expose circular plasmid, linear phage, and high molecular weight genomic DNA samples to a variety of physical, thermal, chemical, and enzymatic conditions that might be expected to affect DNA integrity. The DNA's are analyzed by electrophoresis on a group agarose gel. In the second, they pour and reconstruct a "Frankengel" (a gel containing sections with three di
Chlorine Monoxide from new Microwave Limb Sounder on Aura (WMS)
Chlorine monoxide (ClO) in the atmosphere as measured by the Microwave Limb Sounder (MLS) instrument on NASAs Aura satellite. MLS can simultaneously measure several trace gases and ozone-destroying chemicals in the upper troposphere and photosphere. In this series of animations we present chlorine monoxide (ClO), hydrogen chloride (HCl), nitric acid (HNO3), ozone (O3), water vapor (H2O) and temperature measurements. These are first light data taken when the MLS was operated for the first time. C
10.40 Chemical Engineering Thermodynamics (MIT)
This course aims to connect the principles, concepts, and laws/postulates of classical and statistical thermodynamics to applications that require quantitative knowledge of thermodynamic properties from a macroscopic to a molecular level. It covers their basic postulates of classical thermodynamics and their application to transient open and closed systems, criteria of stability and equilibria, as well as constitutive property models of pure materials and mixtures emphasizing molecular-level eff
Transport Processes in the Environment, Fall 2004
Introduction to momentum and scalar transport in environmental flows, with emphasis given to river and lake systems. Derivation and solutions to the differential form of mass conservation equations. Topics include: molecular and turbulent diffusion, boundary layers, dissolution, phase partitioning, bed-water exchange, air-water exchange, settling and coagulation, buoyancy-driven flows, and stratification in lakes.
Public Health Biology
Offers an integrative molecular and biological perspective on public health problems. Explores population biology and ecological principles underlying public health and reviews molecular biology in relation to public health biology. Modules focus on specific diseases of viral, bacterial, and environmental origin. Uses specific examples of each type to develop the general principles that govern interactions among susceptible organisms and etiologic agents. Devotes special attention to factors tha
Ozone Scenario
During the first kinetics lecture, we traced the efforts of atmospheric chemists to explain the depletion of ozone in the upper atmosphere. (The powerpoint slides have been posted on Blackboard for your review.) U2 spy planes gathered much of the initial data that linked ClO in the stratosphere to the ozone depletion. The data collected during these flights showed the concentrations of various chemical species in the stratosphere, but did not measure how fast the processes were occurring. To det
