Max Planck scientists have discovered how to regulate the formation of proteins in the chloroplasts. They can use so-called riboswitches to switch the genes in the chloroplasts of tobacco plants on and off.
Nature likes some symmetries, but dislikes others. Ordered solids often display a so-called 6-fold rotation symmetry. To achieve this kind of symmetry, the atoms in a plane surround themselves with six neighbours in an arrangement similar to that found in a honeycomb. As opposed to this, ordered materials with 7-fold, 9-fold or 11-fold symmetries do not appear to arise in nature.
Imec announces that it has started work, together with its project partners, on PRIMA, a project under the EU's 7th framework program for ICT (FP7). The project's goal is to improve the efficiency and cost of solar cells though the use of metallic nanostructures.
Preliminary research on cancer treatments using nanotechnology and laser therapy has led to a National Science Foundation (NSF) Faculty Early Career Development (CAREER) award for Marissa Nichole Rylander, Virginia Tech assistant professor jointly appointed in the Department of Mechanical Engineering and Virginia Tech - Wake Forest University School of Biomedical Engineering and Sciences (SBES)
Professor Gary Marchant, Executive Director of the Center for Law, Science and Innovation at the Sandra Day O'Connor College of Law, will deliver a keynote speech on Tuesday, March 30, at a national nanotechnology conference in Arlington, Va.
For the first time ever, a study of this new mathematical model has managed to describe the fracture process for materials such as glass, polymers, concrete, ceramics, metals, rocks, and even certain geological fractures.
New research from mechanical engineers at MIT has revealed a new approach that, by creating specific kinds of tiny structures on a material's surface, can make a droplet spread only in a single direction.
By combining a new generation of piezoelectric nanogenerators with two types of nanowire sensors, researchers have created what are believed to be the first self-powered nanometer-scale sensing devices that draw power from the conversion of mechanical energy.
