Key piece of puzzle sheds light on function of ribosomes

When ribosomes produce protein in all living cells, they do so through a chemical reaction that happens so fast that scientists have been puzzled. Using large quantum mechanical calculations of the reaction center of the ribosome, researchers at Uppsala University in Sweden can now provide the first detailed picture of the reaction.

Neue Optik mit Metamaterialien

Metamaterialien haben besondere optische Eigenschaften: Zum Beispiel brechen sie Licht in eine andere Richtung als alle natuerlichen Materialien, sie haben also einen negativen Brechungsindex. Mit dem EU-Projekt NIM_NIL wollen Wissenschaftler des ISAS solche Metamaterialien fuer sichtbares Licht herstellen.
