Enzymes could break down cell walls faster - leading to less expensive biofuels for transportation - if two enzyme systems are brought together in an industrial setting, new research by the Energy Department's National Renewable Energy Laboratory suggests.
The protein C4BP is similar to a spider in its spatial form with eight 'arms'. The structure of the 'spider body' leads scientists to unconventional ideas - the protein is possibly suitable as a scaffold for the transport of active pharmaceutical substances, particularly biomolecules.
A team of scientists has conducted a study on plants (Arabidopsis) that shows that the site of action of the repression of target gene expression occurs on the endoplasmic reticulum, a cellular organelle that is an interconnected network of membranes - essentially, flattened sacs and branching tubules - that extends like a flat balloon throughout the cytoplasm in plant and animal cells.
Immune cells in newborn humans appear to be more ready to do battle than previously thought. New Cornell research shows that small populations of preprogrammed immune cells can fight specific pathogens that they have never encountered. The findings, say the researchers, have the potential to revolutionize how and when people are immunized.
Nine students who are involved in a multi-institutional effort to produce better blueberries only see the fruit as codes, symbols, numbers and letters on computer screens, rather than the nutritional, sweet treat they love.
A research team led by Cornell University's Creative Machines Lab has created a computer algorithm that can be used to witness virtual creatures evolving their squishy, muscle-like features in order to teach themselves to walk.
Scientists at the Walter and Eliza Hall Institute and their collaborators have tailor-made a new chemical compound that blocks a protein that has been linked to poor responses to treatment in cancer patients. The development of the compound, called WEHI-539, is an important step towards the design of a potential new anti-cancer agent.
Researchers from Huntsman Cancer Institute at the University of Utah have developed a novel and powerful technique to identify the targets for a group of enzymes called RNA cytosine methyltransferases in human RNA.
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.
University 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.
Firefly BioWorks announced today the awarding of $120,000 in twelve research grants to scientists working to expand the frontiers of microRNA research. The Firefly Frontiers Grant is designed for scientists looking to profile large numbers of samples over multiple microRNA targets.
