By understanding the mechanisms by which these proteins work, researchers hope to develop new HIV drugs. Proceedings of the National Academy of Science , March 16, 1999. Chemists at the University of Texas at Austin have developed an artificial tongue that is able to taste different chemicals. The artificial tongue is a chip consisting of permeable beads coated with synthesized receptor molecules that will bind to recognizable molecules. As a sample liquid washes over it, the molecules bind to their receptors, subsequently producing a glow.
Computer software can then trace the glow and identify the composition of the substance.
This new technology could enable lab technicians to taste blood samples for the abundance of glucose or other bloodstream chemicals. The Washington Post , March 22, 1999. X-ray studies conducted on a single human hair taken from breast cancer patients revealed an atypical protein structure. In addition, a few women possessing both a familial cancer history and a genetic mutation had this atypical hair structure. This discovery may pave the way for more affordable treatment for and accurate diagnosis of cancer.
