South Australia came home with a total of 12 awards (diamond, one gold, four silver, two bronze and four highly commended) out of 47 awarded nationally. The Serif awards were orga...Brain imaging technology can reveal what a person is thinking about
Powerful brain imaging technology is allowing researchers to actually tell what a person is thinking before they even say it. A study, published in the November issue of the international Journal of Cognitive Neuroscience, has shown that it is possible for researchers to look at brain imaging ...Claims-based measurement shows many Medicare patients do not receive necessary care

...e liposomes "melt" to varying degrees when heated, allowing the drug inside to escape. "Only tumor blood vessels have gaps in them that allow the passive leaking of liposomes," explained Dewhirst, professor of radiation oncology. "With heat there are more gaps and therefore more liposomes enter the tumor. ...O.R. model could reduce high death rate among kidney dialysis patients by up to 20%
