Wer in der Zelle fuer die Bildung von Proteinen zustaendig ist, ist dank der zellbiologischen Forschung bereits bekannt. Aber wie diese Proteinfabriken (Ribosomen) innerhalb der Zelle organisiert sind, ist bisher nicht umfassend erforscht. Kuerzlich ist es Wissenschaftlern am Max-Planck-Institut fuer Biochemie gelungen, das Innenleben einer intakten menschlichen Zelle mittel Kryo-Elektronentomographie dreidimensional abzubilden.
Nanostructures with Fano resonance fabricated from plasmonic materials and metamaterials could give rise to a range of applications such as label-free chemical and bioanalysis probes that are adaptable to high-throughput applications, electronics-free sensor for sensing physical parameter changes such as temperature or pressure.
Crazy bands are cool because no matter how long they've been stretched around a kid's wrist, they always return to their original shape, be it a lion or a kangaroo. Now a Duke and Stanford chemistry team has found a polymer molecule that's so springy it snaps back from stretching much smaller than it was before.
Researchers at Imperial College London have developed a versatile, practical and efficient method for activating sites on the surface of carbon nanotubes (CNTs) and subsequently binding a wide range of molecules to them. This new method will enable large-scale manufacture of modified CNTs.
European researchers have combined computer modelling of quantum mechanics and precision fabrication processes to create novel transparent conductive oxides made to order for a wide range of scientific and consumer applications.
The integration of single-spin magnetoelectronics into standard silicon technology may soon be possible, if experiments confirm a new theoretical prediction by physicists at the Naval Research Laboratory (NRL) and the University of Wisconsin-Madison. The researchers predict that a family of well-known silicon surfaces, stabilized by small amounts of gold atoms, is intrinsically magnetic despite having no magnetic elements.
The imaging tools developed so far by the European ENCITE project should improve monitoring of cell therapy and improve the understanding of the fate of transplanted cells and the mechanism of action of cell-based therapies. Using the knowledge obtained in these studies, tools and treatment strategies can be further optimised to reap the full benefit of cell-based therapies.
The science behind gecko toes holds the answer to a dry adhesive that provides an ideal grip for robot feet. Stanford mechanical engineer Mark Cutkosky is using the new material, based on the structure of a gecko foot, to keep his robots climbing.
The University of Southern California announced today that Michelle Povinelli, a member of the faculty of the Viterbi School of Engineering, has been recognized by MIT Technology Review magazine as one of the world's top innovators under the age of 35 for her research on the optical properties of nano-structured materials.
If a drug can be guided to the right place in the body, the treatment is more effective and there are fewer side-effects. Researchers at Lund University in Sweden have now developed magnetic nanoparticles that can be directed to metallic implants such as artificial knee joints, hip joints and stents in the coronary arteries.
NanoEngineers at the University of California, San Diego are designing new types of lithium-ion (Li-ion) batteries that could be used in a variety of NASA space exploration projects - and in a wide range of transportation and consumer applications.
