Biotechnology: Artificial Trachea Grown From Stem Cells And Implanted

Harvard Biosciences and a team of international surgeons and scientists have successfully collaborated to create and implant a bioartificial trachea. The trachea was created by growing stem cells onto a spongy scaffold with appropriate physical properties. The growth phase of the process took between 10 to 12 days and included chemical or physical triggers to … Continue reading Biotechnology: Artificial Trachea Grown From Stem Cells And Implanted

Twinkling Quantum Dots May Be Useful For Medical Applications

The nanometer sized fragments of semiconductor absorb light and then radiate the absorbed energy in several different customizable colors.  Their twinkling is considered a result of quantum mechanical effects.  These nano-sized fragments are small enough to attach to and track molecules.  Although tracking molecules would be useful another of their characteristics may be more interesting.  … Continue reading Twinkling Quantum Dots May Be Useful For Medical Applications

Biotechnology Research: D. Melanogaster Descriminates Odors By Isotope Number

Apparently Drosophila Melanogaster, that venerable subject of hundreds of thousands of biology experiments, has demonstrated the ability to discriminate odors by molecular vibration using an unknown process which human beings must employ NMR or a scanning tunneling microscope to duplicate. That is to say that it appears to discriminate differences in odorants which differ only … Continue reading Biotechnology Research: D. Melanogaster Descriminates Odors By Isotope Number
