Newsworthy biotechnology research projects:

• Proteins on a computer chip: A research team headed by distinguished professor Michael Ladisch has mated proteins to silicon chips. Because proteins react to specific cells, like a key matches a lock, these biochips will be able to identify pathogens in food, diseases in people, biological threats used by terrorists, etc., and transmit the information to a handheld computer.

News release: http://news.uns.purdue.edu/uns/html4ever/0007.Ladisch.biochips.html

• Crop improvement: Environmental crop stresses, such as drought, heat, frost, saline soil, and others, reduce yields more than any pests. Researchers Ray Bressan and Paul Hassegawa, co-directors of the Center for Plant Environmental Stress Physiology, have said that within 10 years, advances in this field will allow farmers to plant two crops each year. This would, in turn, allow marginal farmland to be returned to nature.

News releases:



• Saving endangered species: Small populations of reintroduced or endangered animals can die out because of problems brought on by inbreeding. Gene Rhodes, a Purdue wildlife biologist, is improving the odds for these animals through research into the genomes of wildlife.

News release: http://news.uns.purdue.edu/uns/html4ever/9808.Rhodes.genes.html

• Risks of biotechnology: A model to determine the environmental risks of genetically modified organisms, or GMOs, has been developed by two Purdue University researchers. William Muir, professor of animal science, says that such an objective test to assess environmental risk could actually make biotechnology more readily accepted by those currently opposed to it, even if the model points out more problems.

News release: http://news.uns.purdue.edu/uns/html4ever/010625.Muir.transgene.html

• Ethics of biotechnology: Paul Thompson, Purdue's professor of philosophy, is one of the nation's few experts on the ethics of biotechnology. Thompson's research focuses on issues surrounding biotechnology.

• A new lab rat for science: Medical scientists use genetically modified mice to learn about the function of genes, but these mice can cost up to $100,000 each. Paul Collodi is developing technique that would allow the same experiments to be conducted using genetically modified zebrafish, which would only cost a few dollars each.

News release: http://news.uns.purdue.edu/uns/html4ever/Collodi.zebrafish.html

• Comparative biology: Animals and humans share most of their physiological processes. Because of this, the Purdue School of Agriculture and the I.U. School of Medicine are teaming up to research human health problems using animals as stand-ins.

• Cleaning brownfield sites with plants: Genes thought to allow plants to accumulate large amounts of metal in their tissues have been identified and cloned by a Purdue University scientist. The finding is expected to lead to new crop plants that can clean up industrial contamination, new foods that fight disease and reduced work for some farmers.

• Forestalling chemical resistance: Entomologist Barry Pittendrigh has developed a method to use pesticides or antibiotics so that genetic resistance doesn't arise in target organisms. The technique, called negative cross-resistance, involves using multiple compounds in a precise way to stop the pests. Pittendrigh says that by using the model it could delay resistance for decades.

News release: http://news.uns.purdue.edu/uns/html4ever/Pittendrigh.resist.html

• Animal reproduction: Animal scientist Rebecca Krisher is working to understand the biology of oocytes, which are fertilized eggs, in order to improve techniques of animal cloning and to provide new therapies for human infertility.

• Crop nutrient transport: The uptake of plant nutrients is one of the major limiting factors of plant growth. Professor K. Raghothama is studying the molecular biology of how plants transport nutrients within their tissues and has made significant progress in this area.

• Plastic from plants: Researchers have cloned a gene that will allow plants to produce plastics. Currently, petroleum is used to make nearly all plastics; it also is used as a base material or solvent in paints, household and industrial chemicals and in thousands of other applications. But researchers say crop plants such as corn or soybeans hold the potential to create plants that provide the starting materials to make the plastics we already have and develop new plastics with never-before-seen properties.

News release: http://www.purdue.edu/uns/html4ever/0102.Chapple.plastics.html

• Environmental cleanup: Engineers are using genetics to develop a simple, quick method for assessing the progress of environmental cleanup efforts at sites contaminated with petroleum-based pollutants like gasoline and diesel fuel. The work is being done by Loring Nies, associate professor of civil engineering and Cindy Nakatsu, an associate professor of agronomy. Their technique works by screening soil for genes that reveal the presence of an enzyme produced by pollution-busting bacteria. If the enzyme is detected, that means bacteria probably are cleaning the soil. Information about the bacteria's presence and concentration might then be used to assess the progress of efforts to remove toxins from the contaminated soil. The method is more effective and faster than conventional soil-testing techniques.
