Numerous obstacles posed by cellular structures hinder protein movements within the cell. Researchers now have succeeded in mapping the intracellular topology by observing proteins in living cells on multiple time and length scales. By developing a new fluorescence microscopy-based technique, the researchers were able to measure how long it takes proteins to move over distances ranging from 0.2 to 3 micrometres in living cells.
Scientists focus on microtubules as among the most important factors in encouraging injured adult axons to regenerate. Microtubules are hollow polymeric filaments composed of tubulin subunits that provide structural support for the axon.
Researchers have created a biodegradable biomaterial that is inherently antioxidant. The material can be used to create elastomers, liquids that turn into gels, or solids for building devices that are more compatible with cells and tissues.
Researchers have identified cells' unique features within the developing human brain, using the latest technologies for analyzing gene activity in individual cells, and have demonstrated that large-scale cell surveys can be done much more efficiently and cheaply than was previously thought possible.
Thanks to techniques developed at Caltech, scientists can see through tissues, organs, and even an entire body. The techniques offer new insight into the cell-by-cell makeup of organisms - and the promise of novel diagnostic medical applications.
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.
