A University of California, San Diego faculty-student team is about to demonstrate a first-of-its kind, phase-change memory solid state storage device that provides performance thousands of times faster than a conventional hard drive and up to seven times faster than current state-of-the-art solid-state drives.
In many ways, life is like a computer. An organism's genome is the software that tells the cellular and molecular machinery - the hardware - what to do. But instead of electronic circuitry, life relies on biochemical circuitry - complex networks of reactions and pathways that enable organisms to function. Now, researchers at the California Institute of Technology (Caltech) have built the most complex biochemical circuit ever created from scratch, made with DNA-based devices in a test tube that are analogous to the electronic transistors on a computer chip.
A world premiere: a material which changes its strength, virtually at the touch of a button. This transformation can be achieved in a matter of seconds through changes in the electron structure of a material; thus hard and brittle matter, for example, can become soft and malleable.
Seven speakers presented at Johns Hopkins Institute for NanoBioTechnology's fifth annual nano-bio symposium, held May 13, 2011. This year's topic - cancer nanotechnology - was approached from a variety of angles.
Rice University researcher Sibani Lisa Biswal and Kai-Wei Liu, a graduate student in Biswal's lab who recently earned her doctorate at Rice, used microcantilevers as ultrasensitive measuring devices to study how lipid bilayers interact with surfactants.
Das hat die Welt noch nicht gesehen: Ein Werkstoff, der quasi auf Knopfdruck seine Festigkeit aendert. Dieser Wandel in Sekundenschnelle kann durch Aenderungen der Elektronenstruktur eines Materials erreicht und so zum Beispiel aus einem festen und sproeden Stoff ein weicher und formbarer werden. Den entscheidenden Impuls liefern elektrische Signale, Clou dieser sensationellen Entwicklung.
A space flight by millions of microscopic worms could help us overcome the numerous threats posed to human health by space travel. The Caenorhabditis elegans (C. elegans) have also given experts an insight into how to block muscle degradation in the sick and elderly.
Antibiotics are among the greatest achievements of medical science. But lately the former multi-purpose weapon fails in the battle against infectious diseases. Bacteria are increasingly developing resistance to antibiotics. Researchers have now found a therapeutic equivalent which could replace penicillin and related phamaceuticals.
They see more than the naked eye and could make traffic safer: miniaturized thermal imaging sensors. But they are difficult to manufacture on a commercial scale. Researchers have now developed a new system. On it, special micro-electromechanical systems can be produced - with the correct etching technique.
