Scientists have revealed how a bacterial enzyme has evolved an energy-efficient method to move long distances along DNA. The findings present further insight into the coupling of chemical and mechanical energy by a class of enzymes called helicases, a widely-distributed group of proteins, which in human cells are implicated in some cancers.

Read moreUniversity of Chicago researchers have created a synthetic compound that mimics the complex quantum dynamics observed in photosynthesis and may enable fundamentally new routes to creating solar-energy technologies. Engineering quantum effects into synthetic light-harvesting devices is not only possible, but also easier than anyone expected, the researchers report.

Scientists at the Centre for Applied Medical Research (CIMA) at the University of Navarre and the Centre for Genomic Regulation (CRG) in Barcelona have reprogrammed lymphfoma and leukaemia cells in such a way that they are no longer malignant. The resulting cells maintain their new condition of benign cells even when they are not being treated and reduce the possibilities of generating new tumours.

Scientists investigated the effects of introducing a novel artificial neural connection which bridged a spinal cord lesion in a paretic monkey. This allowed the monkey to electrically stimulate the spinal cord through volitionally controlled brain activity and thereby to restore volitional control of the paretic hand.

Researchers at the University of North Carolina at Chapel Hill School of Medicine have 'rationally rewired' some of the cell's smallest components to create proteins that can be switched on or off by command. These 'protein switches' can be used to interrogate the inner workings of each cell, helping scientists uncover the molecular mechanisms of human health and disease.
