"DIGITAL-BIO: Living enzyme acts as molecular switch "
Johns Hopkins University researcher Marc Ostermeier described a single-molecule switch engineered from a strand of a living protein�an enzyme. Such molecular switchs could be applied as super-sensitive sensors that detect even a single molecule of a biological warfare agent. Medically, molecular switches have even wider-scale potential, from early detection of hard-to-diagnosis maladies, to "lethal drug" delivery only to cancerous cells.

"Aufgeladene" Brennstoffzelle soll Leistung verzehnfachen"
Mit dem "Aufladen" von Brennstoffzellen durch Mischen von Brennstoff und Sauerstoff sind extrem flache, in einem Walzvorgang herstellbare Brennstoffzellen zu erwarten. Die Inventor Generics Group Ltd. aus Cambridge in England glaubt, dass die neue Entwicklung die sperrigen Metalltrennplatten �berfl�ssig machen, die Zellgr��en herabsetzen und die Leistungsdichte verzehnfachen wird.
