An international collaboration led by chemists and engineers from the University of Pennsylvania has prepared a library of synthetic biomaterials that mimic cellular membranes and that show promise in targeted delivery of cancer drugs, gene therapy, proteins, imaging and diagnostic agents and cosmetics safely to the body in the emerging field called nanomedicine.
Scientists working at the Advanced Light Source (ALS) at the Lawrence Berkeley National Laboratory have discovered striking new details about the electronic structure of graphene, crystalline sheets of carbon just one atom thick. They found that composite particles called plasmarons play a vital role in determining graphene's properties.
Researchers at the J. Craig Venter Institute made the much-anticipated announcement today that they have created a replicating 'synthetic cell' - a bacterium with its DNA replaced by a 100% prosthetic genome. Eight leading synthetic-biology pundits reflect on what effect Craig Venter's latest achievement could have on science and society.
he newly patented catalysts, as well as a method for making a particular type of catalyst with a thin layer of platinum, could greatly reduce the cost and increase the use of fuel cells in electric vehicles. The catalysts and the technique are available for licensing.
After four years of fine-tuning an effective physical model and massive use of the supercomputer Mare Nostrum, researchers at IRB Barcelona and the Barcelona Supercomputing Center (BSC) have managed to produce the first realistic simulation of DNA opening at high resolution.
Wissenschaftler im Forschungszentrum Dresden-Rossendorf haben einen Weg gefunden, das wenig effektive, amorphe oder nano-kristalline Silizium in Duennschicht-Solarzellen durch einen Nano-Schwamm aus Silizium zu ersetzen.
Light-driven molecular switches are already used in technical devices such as LCD displays and storage media. Full comprehension of the processes at a molecular scale is required to increase their efficiency, but this knowledge had not been available to date.
Researchers have succeeded in producing gel electrolytes for use in a light-control glass device using nanoparticles of Prussian blue-type complexes. The light-control glass device is based on the electrochromism phenomenon, and its color can be controlled between blue and transparent states by application of an electric current.
Neuroengineering is a rapidly growing discipline that takes its lymph from the increasing cross-fertilization of many areas of technology and science. By means of neuroengineering, advances in diverse technologies and in cellular and molecular biology converge into powerful tools to improve our understanding and treatment of neural (dis)functions.
