UA researchers hope to cure diseases with a common brain parasite

By | 1 comment

There might be a parasite in your brain. It’s estimated that up to one-third of the world’s population is infected with the brain parasite Toxoplasma Gondii. The U.S. has a relatively low rate of infected people, estimated to be between 10 to 25 percent. Countries such as France have an infection rate of 60 to 80 percent. As far as parasites go, Toxoplasma Gondii isn’t’ that bad, unless you’ve had a transplant and are left immunocompromised. Folks who have a weakened immune response can suffer brain damage, and even death if infected with toxoplasmosis. University of Arizona researchers are studying whether the unique relationship between the parasite and the brain could lead to breakthroughs in understanding Alzheimer’s and other brain-related illnesses. “There are very few microbes that can persist in the brain without causing symptoms,” said Dr. Anita Koshy, a research physician...

Turning waste products into plastics

By | Comments Off on Turning waste products into plastics

University of Arizona chemists hope to profit on the smelly remains of refined petroleum after discovering a way to turn sulfur into plastic infrared lenses. The process of hydro desulfurization was developed in the 1980s to remove sulfur from petroleum to prevent acid rain. In the years since, sulfur deposits have grown rapidly. The U.S goes through approximately 20 million barrels of oil a day. Five percent of every barrel of oil is sulfur. The sulfur removed from petroleum is often stacked in large pyramid like deposits. Tons of pure elemental sulfur sits in these reservoirs, with minimal practical use. “We have more sulfur in the world then we know what to do with. We talk about this as one of the biggest environmental problems no one knows about,” said Research Chemistry Professor Jeffery Pyun.  While working on research...
