Well, Ed. For starters:

* Preliminary design of an automated oxygen enrichment system for premature babies. Working with Los Angeles County/USC Medical Center, NASA's retired volunteers and doctors are working to remove the inaccuracies of manually controlled oxygen systems, which can affect the infant's eyesight, brain and lung development.

* Solving a blood clot problem found with a stent that could cause heart attacks. NASA introduced a special electropolishing process to provide a super-smooth stent surface. The electropolishing process, developed in the aerospace industry, is not well known by doctors. The resulting electropolished stent practically eliminated further blood clot formation with the device.

Using space technology, scientists have developed extraordinary ceramic photocells that could repair malfunctioning human eyes.

NASA-funded scientists are crafting microscopic vessels that can venture into the human body and repair problems - one cell at a time.

Using space technology, NASA-funded researchers are developing artificial bones for pain-free hip implants.

Using a space-age device called a bioreactor, researchers have grown patches of tissue that beat and respond much like a human heart does.

NASA- and industry-sponsored research aimed at growing plants in space has led to a device that attacks and destroys airborne pathogens -- like Anthrax.

... not to mention GPS, satellite communications, aeronautic research and advancement and whatnot...

...but I digress.

* Creation of an advanced-database private computer network for pediatricians. Working with Childrens Hospital Los Angeles, NASA professionals and retirees are helping pediatricians nationwide to correspond about children's illnesses using JPL's method of data management. This database will provide a depository for historical data of diagnoses, research, treatments and results. Doctors estimate that extended medical use of the computer database systems could reduce health care costs by 20 to 30 percent.
