Detecting Bird Flu: New Lab-on-chip Identifies H5N1 In Thirty Minutes (September 25, 2007) -- Scientists have developed a miniature device that, if successfully commercialized, could be deployed in affected regions for preemptive surveillance of a nascent avian flu epidemic. The device can ... > full story

Biosensors: When Proteins, Antibodies And Other Biological Molecules Kiss, Biosensor Can Tell (September 25, 2007) -- When biological molecules kiss, a new kind of biosensor can tell: a new and deceptively simple technique can measure the interactions between free-floating, unlabeled biological molecules including ... > full story

Interaction Of DNA And Enzyme Fending Off Virus Caught On Film (September 22, 2007) -- For the first time scientists have been able to film, in real time, the nanoscale interaction of an enzyme and a DNA strand from an attacking virus. Researchers have used a revolutionary Scanning ... > full story

New Technology For Cancer Screening Listens For The Signs Of Cancer (September 22, 2007) -- Cancer-sensing devices built as cheaply and efficiently as wristwatches -- using many of the same operating principles -- could change the way clinicians detect, treat and monitor cancer in patients. ... > full story

Putting Stem Cell Research On The Fast Track (September 21, 2007) -- Engineers have developed tools to help solve two of the main problems slowing the progress of stem cell research -- how to quickly test stem cell response to different drugs or genes, and how to ... > full story

New Way To Watch The Lipid Flip: Flippases, Flopases, And Scramblases (September 20, 2007) -- The "lipid flip" may sound like a rock and roll dance craze from the 1960s. However, it actually is a key biochemical process in which fatty materials termed lipids move into cells -- movements that ... > full story

New Nanoparticle Vaccine Is Both More Effective And Less Expensive (September 20, 2007) -- Good news for public health: Bioengineering researchers have developed and patented a nanoparticle that can deliver vaccines more effectively, with fewer side effects, and at a fraction of the cost ... > full story

Better Displays On Laptop Computers, Cell Phones Coming Soon (September 19, 2007) -- Chemists working at the nanoscale have developed a new, inexpensive means of forcing luminescent polymers to give off polarized light and of confining that light to produce polymer-based lasers. The ... > full story
