DNA methylation, the addition of a methyl group to specific locations on a DNA strand, plays a critical role in determining which genes are active in a cell at any given time. It plays an important role in embryonic development, cell growth and reproduction, and many diseases, including cancer. Now, researchers collaborating at the Mayo Clinic and the University of Illinois in Urbana-Champaign have developed a novel single molecule test for detecting DNA methylation that should greatly simplify and advance the study of this important genomic process.
Engineering researchers treated thin films of polytetrafluoroethylene - a popular polymer used as a dry lubricant for machine components - with silica nanoparticles and found that the filler material significantly reduced wear of the polymer while maintaining a low level of friction.
In a new report, the Parliamentary Assembly recommends that the Council of Europe should set legal standards on nanotechnology based on the precautionary principle, but which will not hinder nanotechnology's potential beneficial use.
LAST POWER, the European Union-sponsored program aimed at developing a cost-effective and reliable technology for power electronics, today announced its three-year program achievements that place Europe at the forefront of research and the commercialization of energy-efficient devices for industrial and automotive applications, consumer electronics, renewable-energy conversion systems, and telecommunications.
Cornell researchers Jenny Sabin, assistant professor of architecture, and Dan Luo, professor of biological and environmental engineering, are among the lead investigators on a new research project to produce 'buildable, bendable and biological materials' for a wide range of applications.
Researchers at National Nanotechnology Center (NANOTEC) in Bangkok and Imperial College London (Department of Chemistry) in United Kingdom have studied the advancements of solid-state nanopores for the purpose of highlighting selected developments that will benefit scientists.
Calculations by the Rice lab of theoretical physicist Boris Yakobson found a graphene/boron anode should be able to hold a lot of lithium and perform at a proper voltage for use in lithium-ion batteries.
Scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) have reported the first fully integrated nanosystem for artificial photosynthesis. While 'artificial leaf' is the popular term for such a system, the key to this success was an 'artificial forest'.
Researchers used a hydrogel to mimic the heart cells. They added carbon nanotubes to the hydrogel, making it conductive, and then injected the material into the heart, where it solidifies at body temperature.
