Researchers hoping to design new materials for energy uses have developed a system to make synthetic polymers with the versatility of nature's own polymers, the ubiquitous proteins. Based on an inexpensive industrial chemical, these synthetic polymers might one day be used to create materials with functions as limitless as proteins, which are involved in every facet of life.
Using cryo-electron microscopy (cryo-EM), scientists have made a significant breakthrough in our understanding of how our molecular machinery finds the right DNA to copy, showing with unprecedented detail the role of a powerhouse transcription factor known as TFIID.
Scientists develop novel way to inject healthy human nerve cells into the brain. The technology involves converting adult tissue-derived stem cells into human neurons on 3-D scaffolds, or tiny islands, of fibers.
Scientists have developed a 3D micro-scaffold technology that promotes reprogramming of stem cells into neurons, and supports growth of neuronal connections capable of transmitting electrical signals. The injection of these networks of functioning human neural cells - compared to injecting individual cells - dramatically improved their survival following transplantation into mouse brains.
