Potassium: an ion with dangerous airs and graces

Potassium Channels Rule over Insulin Release with an Ion Fist

Single-nucleotide polymorphisms (SNPs) are a class of attractive genetic markers for population genetic studies and for identifying genetic variations underlying complex traits. However, the usefulness and efficiency of SNPs in comparison to microsatellites in different scientific contexts, e.g., population structure inference or association analysis, still must be systematically evaluated thro...

Determination of sodium and potassium with ion-selective electrodes.

We compared different sample-handling techniques for measurement of Na+ and K+ with ion-selective electrodes (ISE). Imprecision was less for venous blood (with a minimum of heparin) than for plasma, serum, or capillary blood. The results for K+ were higher for serum than for whole blood, and higher for whole blood than for plasma. The latter difference was apparently due to release of K+ during...

Persuasion, Social Graces, and Computer Security

Although computer users want to behave securely, they often lack the motivation and confidence to protect themselves and their computers. In this paper, we propose a framework that harnesses aspects of social interaction and the Media Equation for designing a novel approach to persuasive technology for computer security. We then apply this framework to anti-virus software, and show how this soc...
