Group XI (2004-2006) News

Technology Seminar, July 19-22, 2005

by Paul Mayou, Group XI participant, Waupaca

Many years ago someone imparted this thought to me concerning scientific advances: “Future reality is only limited by our imaginations”.  After the technology seminar in Madison I am inclined to think that most members of Group XI would agree with that thought. 

We were exposed to a wide array of stunning advances in technology including genomics, nanotechnology, and stem cell research.  Genomics studies every gene in an organism at one time.  The medical, agricultural and industrial implications of advances in genomics are incredible.  This technology can manipulate organisms on a genetic level to, among other things, eliminate defects and weaknesses.

Nanotechnology is defined as 1 billionth of a meter, which is larger than an atom but smaller than a cell, which means your skin will not keep them from entering your body.  Nanoparticles, which possess very high strength and reactivity, are being used in cosmetics, drugs, food and packaging.  Nanosensors are being used in farm fields to monitor soil temperature, moisture and ph levels.  “Biomems” are currently being developed that will act as micromachines with a biological component.  Applications for nanotechnology are extensive and will continue to be incorporated into our daily lives.

Stem cell research has been in the news the past few years and we had an opportunity to explore this more. Stem cells come from human embryos and can be programmed to replace human body parts.  This is accomplished primarily through a process known as “therapeutic cloning” where the nucleus of an egg is removed and replaced with the nucleus of a cell from the person being treated.  This results in genetically compatible stem cells that will not be rejected.

The time we spent at the UW medical facilities revealed amazing advances including robotic surgery, mechanical assistance devices for the heart and, to the relief of those of us in their 50’s or older, virtual colonoscopy.

There are several moral issues surrounding all of these technologies.  Lively discussions occurred involving “the tinkering with nature”, the argument of “just because we can, should we?” and the comparison of morality vs. discomfort.  Advances in new medical technology are very expensive and treatment decisions, some involving life and death, will increasingly be driven by a patient’s ability to pay.

The highlight of the week was attending a presentation by Dr. Hector DeLuca, a pioneer in the research of Vitamin D.  His work and resulting advances with the vitamin D molecule have helped ease the pain and improve the lives of millions of people suffering from the debilitating bone disease known as “rickets”.  It was truly an honor be in the presence of a legend such as Dr. DeLuca.

Group XI left Madison with a new understanding of the numerous, significant breakthroughs occurring in many fields of research.  We can all be very proud of our university and state knowing that they are shining stars in the world of discovery and technological advances.

This seminar was chaired by Andy Lewis, Professor, Center for Community Economic Development, UW Cooperative Extension.
