A team of polymer chemists and engineers from Carnegie Mellon University have developed a new methodology that can be used to create a class of stretchable polymer composites with enhanced electrical and thermal properties. These materials are promising candidates for use in soft robotics, self-healing electronics and medical devices. The results are published in the May 20, 2019 issue of Nature Nanotechnology.
One of the big issues with sustainable energy systems is how to store electricity that's generated from wind, solar and waves. At present, no existing technology provides large-scale storage and energy retrieval for sustainable energy at a low financial and environmental cost. Engineered electroactive microbes could be part of the solution.
'A major aspect of our research is that it just really illustrates how complex all these different components are going on inside a person's body,' said Andrew Ford.
A team of researchers from Tokyo University of Science, Meiji University, and Tokyo University of Agriculture and Technology, led by Professor Takayuki Arazoe, has recently established a series of novel strategies to increase the efficiency of targeted gene disruption and new gene 'introduction' using the CRISPR/Cas9 system in the rice blast fungus Pyricularia (Magnaporthe) oryzae.
Researchers at EPFL are working on a technology to exploit osmotic energy -- a source of power that's naturally available at estuaries, where fresh water comes into contact with seawater. In a laboratory experiment, the team reproduced the real-world conditions that occur where rivers meet the sea (pH and salt concentration) and showed that, by shining light on a system comprising salt, water and a membrane three atoms thick, it was possible to optimize electricity production.
Belgian research groups from the VIB, Ghent University, Ghent University Hospital, and the biotech company argenx have solved a century-long puzzle about the presence of protein crystals in asthma. Normally, proteins do not crystallize in the body, but there are some instances where this process does occur. The study is published in the leading journal Science.
Model organisms have advanced the study of genomics, eukaryotic biology, and evolution. An important resource for any model organism is a near-complete reference genome. Caenorhabditis elegans have been widely studied due to their short generation time and transparent anatomy and were one of the first multicellular organisms sequenced, yet gaps in their reference genome remain. Three studies, published today in Genome Research, provide novel insights into C. elegans genomics and gene expression.
Indiana University researchers have synthesized a powerful new molecule to trap chloride salts. The technology has the potential to reduce its seepage into freshwater systems, which is a threat to drinkable water across the globe.
Researchers from the Hubrecht Institute developed a human model in which they use organoids, or mini organs, to study the function of specific genes that are mutated in liver cancer. Using this method, they have found that mutations in BAP1, a gene commonly mutated in liver cancer, changes the behavior of the cells, which may make them more likely to be invasive. Their results were published in Cell Stem Cell.
Wake Forest Institute for Regenerative Medicine (WFIRM) researchers have shown the feasibility of bioengineering vascularized functional renal tissues for kidney regeneration, developing a partial augmentation strategy that may be a more feasible and practical approach than creating whole organs.
