Lab-on-chip advance uses low-cost, disposable paper strips
January 26, 2011 7:26 am | by Emil Venere | News | CommentsWith current systems that use paper test strips, pH or blood sugar can be measured, but more complex chemical assays can’t be perfomed. Purdue researchers have now, however, introduced “paper microfluidics” by etching patterns by laser using readily available hydrophobic paper.

New technique sees deep brain neurons for months at a time
January 16, 2011 8:56 am | News | CommentsBecause light microscopy can only penetrate the outermost layer of tissues, any region of the brain deeper than 700 micrometers cannot be reached by traditional microscopy techniques. Researchers at Stanford University have broken through this barrier by placing tiny glass tubes, about half the width of a grain of rice, in the deep brain of an anaesthetized mouse.
Study: Consumers not fazed by DNA health results
January 12, 2011 12:43 pm | by Malcolm Ritter, AP Science Writer | News | CommentsConsumers who get their DNA tested for health risks take the results in stride, according to a study conducted by Scripps Health and the U.S. government. It showed that recipients of genetic testing similar to "direct-to-consumer" options not available not only didn't sweat the results, they didn't act on them either, such as eating better or exercising more.
