Changes in the bases that make up DNA act as markers, telling a cell which genes it should read and which it shouldn't. A British team has now introduced a new method that makes it possible to enrich the rare gene segments that contain the modified base hydroxymethylcytosine and to identify individual hydroxymethylcytosine molecules in DNA.
University of Nebraska-Lincoln materials engineers have developed a structural nanofiber that is both strong and tough, a discovery that could transform everything from airplanes and bridges to body armor and bicycles.
Researchers at Northeastern University in Boston have developed a gene therapy approach that may one day stop Parkinson's disease (PD) in it tracks, preventing disease progression and reversing its symptoms. The novelty of the approach lies in the nasal route of administration and nanoparticles containing a gene capable of rescuing dying neurons in the brain.
A successful project to educate school pupils across Bristol and South Gloucestershire about nanotechnology has climaxed in a debate about whether the manipulation of very small particles could be the answer to the world's energy problems.
Already renowned for its beneficial effects on human health, green tea could have a new role - along with other natural plant-based substances - in a healthier, more sustainable production of the most widely used family of nanoparticles, scientists say.
In complex experiments, scientists determined the battery voltage of typical representatives of ReRAM cells and compared them with theoretical values. This comparison revealed other properties (such as ionic resistance) that were previously neither known nor accessible.
Physiker der Universität Leipzig haben gemeinsam mit Wissenschaftlern aus Göttingen eine Laserapparatur zur Erzeugung extrem kurzwelliger UV-Strahlung an Nanostrukturen im Labor entwickelt und damit einen wichtigen Schritt zur Erforschung extrem schneller oder sehr kleiner Objekte getan.
Using swarms of untethered grippers, each as small as a speck of dust, engineers and physicians have devised a new way to perform biopsies that could provide a more effective way to access narrow conduits in the body as well as find early signs of cancer or other diseases.
Researchers from North Carolina State University have solved a long-standing materials science problem, making it possible to create new semiconductor devices using zinc oxide -- including efficient ultraviolet lasers and LED devices for use in sensors and drinking water treatment, as well as new ferromagnetic devices.
