A team of researchers has identified the genes and enzymes that create a promising compound - the 19 carbon furan-containing fatty acid (19Fu-FA). The compound has a variety of potential uses as a biological alternative for compounds currently derived from fossil fuels.
Scientists have grafted neurons reprogrammed from skin cells into the brains of mice for the first time with long-term stability. Six months after implantation, the neurons had become fully functionally integrated into the brain.
A powerful new tool that can help advance the genetic engineering of 'fuel' crops for clean, green and renewable bioenergy, has been developed by researchers with the U.S. Department of Energy (DOE)?s Joint BioEnergy Institute (JBEI). The JBEI researchers have developed an assay that enables scientists to identify and characterize the function of nucleotide sugar transporters, critical components in the biosynthesis of plant cell walls.
Scientists have discovered that stem cells inside the soft tissues of the tooth come from an unexpected source, namely nerves. These findings contribute to brand new knowledge of how teeth are formed, how they grow and how they are able to self-repair.
Around 75 per cent of the supposed functionless DNA in the human genome is transcribed into so-called non-coding RNAs (ribonucleic acid). To date, little is known about its function. Researchers have now been able to demonstrate that the production of non-coding RNAs is precisely regulated. They suspect that non-coding RNAs might play a role in regulating cellular processes or in the modified immune response following exposure to environmental toxicants.
Researchers have demonstrated a dramatically improved technique for analyzing biological cells and tissues based on characteristic molecular vibrations. The new technique is an advanced form of Raman spectroscopy that is fast and accurate enough to create high-resolution images of biological specimens, with detailed spatial information on specific biomolecules, at speeds fast enough to observe changes in living cells.
