Abandon the Alliance? How China’s rise will shape Australia’s future
Professor Hugh White's recent Quarterly Essay, Power Shift: Australia's future between Washington and Beijing looks at Australia's strategic choices in the Asian Century. In this lecture professor white explores the implications for Australia's US alliance. He argues that we can all see how China's rise will transform Australia's economy, but we find it harder to recognize the implications for Australia's political and strategic future. We take for granted the protection that America provid
Must Climate Change End The Platinum Age
In the inaugural S.T. Lee Lecture on Asia and the Pacific Professor
Garnaut asks: How the risks of climate change will interact with the
'Platinum Age' of global economic growth? What are the limits for
global emissions within which the world will need to live if the risk
of dangerous climate change is to be kept within acceptable bounds?
What principles could be reasonably applied to the allocation of a
global emissions budget amongst countries? What global emissions budget
would make sense for
China U.S. Climate Conference
Opening Session: The University, Scientific Research, and Climate Change
Running Time: 1 hour, 22 minutes
This panel will highlight the mutual vulnerability of China and the U.S. to climate change, and the indispensable role of scientific research in understanding the problem and developing solutions.
What's at Risk? Climate Model Predictions and Physical and Biological Impacts
Running Time: 1 hour, 17 minutes
This panel of climate scientists will describe the state of scientific knowledge rega
Emerging Markets in a Nutshell
Three leading academics discuss emerging markets and explore both the issues faced by the economies in China and Latin America and the challenges faced by companies looking to invest in or do business with them. Emerging markets are fast growing economies in a transitional stage between developing and developed. They offer a wealth of opportunities in trade, technology transfer and foreign direct investment, but there are also risks involved. Three leading academics discuss emerging markets and
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.
A Gift of Opportunity: Harry Colmery and the GI Bill of Rights
Harry Colmery, a Topekan, is credited with writing the initial draft of the Servicemen's Readjustment Act of 1944, better known as the GI Bill of Rights. He was part of a committee formed by the national American Legion to secure benefits for those men and women who served in World War II. This pod cast features Colmery's testimony to Congress about what the United States owed to the men and women who had fought for the freedom and liberty of their country. Many historians credit the GI Bill w
Benefits of Standardized Diabetes and Hypertension Screening Forms at Community Screening Events
The objectives of this project were to (a) assess hypertension and diabetes screening data collection practices and guidelines and (b) develop and test standardized screening forms for use at minority community- and faith-based screening events. Project Phase I involved resource assessment and the development of a set of screening forms and guidelines containing a core data set for both hypertension and diabetes. These were then tested during Phase II at predetermined communitybased screening ev
Fungal footbaths could save the honey bee
Globally, the honey bee population is in decline. This has serious implications for the cross pollination of commercial crops and wild plants. One of the major causes of this decline is the Varroa Destructor mite. However, researchers at Warwick University may have found a natural solution to this problem. Dr Dave Chandler from Warwick HRI explains how.
Understanding cancer: News from the frontline
This Oxford at Said seminar was dedicated to cancer research. Three researchers from the University of Oxford give insights into recent advances in the field of cancer cell biology, therapy and epidemiology. One in three people develop cancer, and one in five in Europe and North America die of the disease. Although environmental and lifestyle factors, for example smoking or sun exposure, affect the incidence of some cancer types, all human populations and many types of animal suffer from this di
Cyanobacteria Health Page
This Centers for Disease Control and Prevention (CDC) Health Studies page focuses on cyanobacteria, single-celled organisms thought to be the origin of plants. Cyanobacteria live in fresh, brackish, or marine water and are of concern to the CDC and Environmental Protection Agency (EPA) because some can form harmful blooms that deplete the oxygen and block sunlight that other organisms need to live. They can also produce powerful toxins that affect the brain and liver of animals and humans. This
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.
Detection of Genetically Modified Foods
Genetically modified foods are often in the news and widely grown in the United States. Three US government agencies (USDA, FDA, and EPA) work to regulate the introduction and production of genetically modified foods. These crops can provide agricultural, ecological and nutritional benefits, but there are also potential risks to the environment and consumers. As consumers and public interest groups around the world have become aware of these risks, there has been a call for more explicit product
Chemiosmotic Principles of Solute Transport in Barley Roots
This exercise will demonstrate to students the fluxes of certain inorganic ions in the roots of barley plants. It will familiarize them with the chemiosmotic principles that are involved in ATP synthesis and give them an understanding of solute transport.
Bacterial Quorum Sensing and Bioluminescence
The bacterium Vibrio fischeri produces light when it is growing symbiotically in the light organ of certain fish and squid species. The bacteria sense they are in a light organ because they are present at a high bacterial cell density, which they detect through "quorum sensing." We use several bacterial strains, each of which carry only part of the genes responsible for the quorum sensing and bioluminescence process. We use chemical and genetic complementation to determine which genes are lackin
Vegetation Images Show Drought in Western US (WMS)
Satellite data can gauge the health of plants, which is a good indicator of drought. The Normalized Difference Vegetation Index (NDVI) measures how dense and green plant leaves are. NDVI images are useful as a measure of drought when compared to "normal" plant health. Scientists calculate average NDVI values for an area to find out what is normal at a particular time of year. This animation uses satellite imagery to show changes in vegetation between 1999 and 2003. In 2002, drought had settled a
Advanced semiconductor devices are a new source of energy for the 21st century, delivering electricity directly from sunlight. Suitable semiconductor materials, device physics, and fabrication technologies for solar cells are presented in this course. The guidelines for design of a complete solar cell system for household application are explained. Cost aspects, market development, and the application areas of solar cells are presented.
