Microscopy reveals how atom-high steps impede oxidation of metal surfaces Posted: 29 Dec 2014 12:22 PM PST Certain features of metal surfaces can stop the process of oxidation in its tracks, new research has found. The findings could be relevant to understanding and perhaps controlling oxidation in a wide range of materials—from catalysts to the superalloys used in jet engine turbines and the oxides in microelectronics.

New half-light half-matter quantum particles created Posted: 29 Dec 2014 11:14 AM PST Prospects of developing computing and communication technologies based on quantum properties of light and matter may have taken a major step forward thanks to new research.

A qubit candidate shines brighter Posted: 29 Dec 2014 09:26 AM PST Scientists taken a major step forward in effectively enhancing the fluorescent light emission of diamond nitrogen vacancy centers -- a key step to using the atom-sized defects in future quantum computers. The technique hinges on the very precise positioning of NV centers within a structure called a photonic cavity that can boost the light signal from the defect.

Development of software that 'predicts' sudden cardiac death Posted: 24 Dec 2014 07:30 AM PST At Galway Hospital, in Ireland, a device is currently used to "predict" cardiac events in people at risk of sudden cardiac death. This technology was developed by a Mexican, and the city's University patented it looking to sell it to specialized companies.
