Biomedical engineers at Duke University have developed a way of modeling how potentially beneficial packages of DNA called plasmids circulate and accumulate through a complex environment that includes many bacterial species. The researchers hope that their new model will lay the groundwork for others to better model and predict how important traits such as antibiotic resistance in pathogens or metabolic abilities in bacteria bred to clean environmental pollution will spread and grow in a given environment.
Reverse osmosis is one of the most widely used techniques for the desalination of water. Some of the membranes currently used are artificial channels of water inserted into lipid layers. But their large-scale performance is not satisfactory. An international team has developed a hybrid strategy, which consists of combining a polyamide matrix and artificial water channels into a single structure. Their membranes have been tested under industrial conditions and outperform conventional membranes.
A team of researchers from Kaunas University of Technology and Lithuanian University of Health Sciences proposed a non-invasive method for detection of melanoma. A patented computer-aided diagnostic system developed by Lithuanian scientists proved to be more than 90% accurate in detecting malignancy in diagnostic images of skin lesions acquired from 100 patients.
An invention similar to an elephant's trunk has potential benefits for many industries where handling delicate objects is essential, say the UNSW researchers who developed it.
Researchers from the Institut national de la recherche scientifique (INRS) have shown that nanoparticles could be used to deliver drugs to the brain to treat neurodegenerative diseases.
Researchers at Duke University and the University of California, Los Angeles, have developed a biomaterial that significantly reduces scar formation after a wound, leading to more effective skin healing. This new material, which quickly degrades once the wound has closed, activates an adaptive immune response that can trigger regenerative wound healing, leaving behind stronger and healthier healed skin.
The present review describes the basic principle and the instrumentation of IR spectroscopy along with its advancements. Beyond this, various applications of this technique in determination of protein structure and quantification in different materials such as foods stuffs, biotechnological products and biological fluids have also been summarized.
A group of international scientists summarized the epidemiologic and mechanistic evidence in support of an association between noise and air pollution with cardiovascular and metabolic disease, and recommended comprehensive mitigation measures.
To also address the controversies on the feasibility of 3D printing for membranes, researchers from SUTD and NTU have coined a new term 'hybrid additive manufacturing' for the water treatment industry.
Researchers at the University of Colorado Boulder are developing a wearable electronic device that's 'really wearable'--a stretchy and fully-recyclable circuit board that's inspired by, and sticks onto, human skin.
