A research team at the University of Delaware has developed technology to program strands of DNA into switches that turn proteins on and off. This technology could lead to the development of new cancer therapies and other drugs.
In a new study, researchers from the US Department of Energy's Argonne and Brookhaven National Laboratories observed the formation of two kinds of defects in individual nanowires, which are smaller in diameter than a human hair.
Two novel materials, each composed of a single atomic layer and the tip of a scanning tunneling microscope - these are the ingredients to create a novel kind of a so-called 'quantum dot'. These extremely small nanostructures allow delicate control of individual electrons by fine-tuning their energy levels directly. Such devices are key for modern quantum technologies.
For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of living zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
An international research team discovered a new type of curved light beams, dubbed a "photonic hook". Photonic hooks are unique, as their radius of curvature is two times smaller than their wavelength. This is the smallest curvature radius of electromagnetic waves ever recorded. Photonic hook can improve the resolution of optical systems and control the movement of nanoparticles, individual cells, viruses or bacteria. Results of this research were published in Optics Letters and Scientific Reports.
Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Wyss Institute for Biologically Inspired Engineering have developed new wound dressings that dramatically accelerate healing and improve tissue regeneration. The two different types of nanofiber dressings, described in separate papers, use naturally-occurring proteins in plants and animals to promote healing and regrow tissue.
Paul Voyles, the Beckwith-Bascom Professor in materials science and engineering at the University of Wisconsin-Madison, and collaborators in Madison and at Yale University have made significant experimental strides in understanding how, when and where the constantly moving atoms in molten metal 'lock' into place as the material transitions from liquid to solid glass.
Microfluidic device developed by Massachusetts General Hospital investigators may help solve a significant and persistent challenge in medicine -- diagnosing the life-threatening complication of sepsis.
An expected effect, known as zero field switching, could enable lower-power memory and computing devices than presently possible.
A novel quantum effect observed in a carbon nanotube film could lead to the development of near-infrared lasers and other optoelectronic devices, according to scientists at Rice University and Tokyo Metropolitan University.
