Sildenafil citrate, commonly known as Viagra, is currently the first choice drug for erectile dysfunction but despite its success oral delivery of the drug is hampered by numerous side effects, the long delay before it starts working and the short amount of time it lasts. Researchers in Egypt think they may have a solution via nanotechnology.
Researchers who have been working for nearly a decade to piece together the process by which an enzyme repairs sun-damaged DNA have finally witnessed the entire process in full detail in the laboratory.
Storing quantum information correctly and permanently has not been possible thus far. The latest studies show that topological memory harbours great potential in this respect - but only if the interferences that eventuate stay put instead of spreading.
Taking advantage of the unique properties of zinc oxide nanowires, researchers have demonstrated a new type of piezoelectric resistive switching device in which the write-read access of memory cells is controlled by electromechanical modulation. Operating on flexible substrates, arrays of these devices could provide a new way to interface the mechanical actions of the biological world to conventional electronic circuitry.
Working in collaboration with the RhineMain Polytechnic, materials scientists at the TU Darmstadt have developed an extremely sensitive explosives sensor that is capable of detecting even slight traces of the high-explosive chemical compound pentaerythritol tetranitrate (PETN). Terrorists had employed PETN in several attacks on commercial aircraft.
Materialwissenschaftler der TU Darmstadt haben in Zusammenarbeit mit der Hochschule RheinMain einen ausserordentlich sensiblen Sprengstoffsensor entwickelt. Dieser kann geringste Spuren der hochexplosiven Chemikalie Pentaerythrityltetranitrat (PETN) nachweisen. Terroristen hatten PETN bei mehreren Anschlagsversuchen auf Flugzeuge eingesetzt.
Prof. Dr. Juergen Popp und Prof. Dr. Stefan Heinemann von der Uni Jena haben den ersten Teil eines umfassenden Handbuchs zur Biophotonik herausgebracht. Das Handbook of Biophotonics Bd. 1 erklaert die naturwissenschaftlichen Grundlagen der Licht-Materie-Interaktion und soll so die Zusammenarbeit von verschiedenen wissenschaftlichen Disziplinen in der Biophotonik erleichtern.
Looking to improve upon current methods of imaging, researchers from the California Institute of Technology (Caltech) have developed a novel approach that could redefine optical imaging of live biological samples by simultaneously achieving high resolution, high penetration depth (for seeing deep inside 3D samples), and high imaging speed.
Commissioner Maire Geoghegan-Quinn announced nearly EUR 7 billion to kick-start innovation through research. The European Commission's biggest ever such funding package, under the EU's Seventh Framework Programme for Research (FP7), is expected to create around 174 000 jobs in the short-term and nearly 450 000 jobs and nearly EUR 80 billion in GDP growth over 15 years. EUR 488 million for nanotechnologies will focus on areas such as factories of the future, green cars and energy efficient buildings.
