Enzyme structure reveals how DNA is opened up for transcription

DNA is a molecular manual that contains instructions for building life. And, like any manual, DNA isn't all that useful if it remains unopened and unread. In order to transcribe DNA, the enzyme RNA polymerase, or RNAP, must ...

Reliable molecular toggle switch developed

Nanotechnology constantly allows for new records in miniaturization. Reduction of the dimension of electronic components, however, has physical limits that will be reached soon. Novel materials and components are required. ...

Moving beyond semiconductors for next-generation electric switches

Computers use switches to perform calculations. A complex film with "quantum wells"—regions that allow electron motion in only two dimensions—can be used to make efficient switches for high-speed computers. For the first ...

Graphene slides smoothly across gold

Graphene, a modified form of carbon, offers versatile potential for use in coating machine components and in the field of electronic switches. An international team of researchers led by physicists at the University of Basel ...

Switching superconductivity by light

A research team led by Prof. Hiroshi M. Yamamoto of the Institute for Molecular Science, National Institutes of Natural Sciences has developed a novel superconducting transistor which can be switched reversibly between ON ...
