‘Sí’ on the new SI: NIST backs proposal for a revamped...

Taking the first steps of what would be a major historical advance in the science of measurement, the National Institute of Standards and Technology (NIST) is participating in a worldwide effort to recommend major revisions to the Internationa...

Prediction of intrinsic magnetism at silicon surfaces could lead to single-spin...

The integration of single-spin magnetoelectronics into standard silicon technology may soon be possible, if experiments confirm a new theoretical prediction by physicists at the Naval Research Laboratory (NRL) and the University of Wisconsin-Madis...

Silicon storage: That’s a lot of data!

Richard Feynman once said that all the information in all the books in the world could theoretically fit in a cube 1/200th of an inch on a side. Looks like he got it right, says Technology Research News. Reporting on advances in data storage, the magazine says researchers at the University of Wisconsin, Madison have demonstrated the successful use of single silicon atoms to represent the ones and zeroes that are modern data storage. The result, in theory, is the ability to store the equivalent of 7,800 DVDs in one square inch of material. Engineering limitations mean writing atomic bits is impractically slow at the moment. But the Madison work is a realistic analysis of bit stability and recording density, says one scientist who has examined the work.
