HTTP:: Bad Bananas 039 Glow 039 Blue in Ultraviolet Wavelengths
--------
An international group of researchers has recently discovered the fact that banana peels, which may be a clear indicator that the fruits have gone bad on the inside, do not change their aspect as they deteriorate. At least not in visible wavelengths. When researchers placed the peels under ultraviolet (UV) light, they discovered that, if spoiled, they gave off a blue glow. The team determined that this was caused by chlorophyll aging and beginning to disintegrate, the US National Science Foundation (NSF) informs. In charge of the new investigation were experts Nicholas Turro, from the Columbia University, and Bernhard Krautler, from the University of Innsbruck. In their new paper, which appears in the latest issue of the respected journal Proceedings of the National Academies of Sciences (PNAS), they show that chemists and molecular biologists could have a field day with the new-found knowledge. If molecules become “trackable” in UV light when they are around dying tis!
sue, then the research holds promise for further investigating the process known as programmed cellular death (PCD). “This work brings to fruition some of the remarkable principles of fundamental organic photochemistry harvested from more than four decades of Professor Turro's research at Columbia,” NSF Ch...
