DNA barcode finds four new bird species
...s of DNA barcoding envision developing a hand-held device
that amateur naturalists and others could take outdoors for species identification. "New species won't be determined by DNA analysis alone," says Stoeckle. "Morphology, behavior, and vocalization, for example, will still need to be accounted for...
Scientists find nanowires capable of detecting individual viruses
... or otherwise. Lieber says that any anti-bioterror device
built around nanowires' virus-detecting capabilities would most likely marry the technology with a microfluidic apparatus that would draw in air, suspend any airborne particles in a liquid, and then run this solution past the nanowire array. Lieber'...

Jefferson Lab detector technology aids development of cystic fibrosis therapy
... Weisenberger agrees. "I think a tri-modal imaging device
has the potential to bring a very powerful tool to biomedical research. The first modality, x-ray, tells you about structure. The other two modalities, gamma emission and optical, can both give you information on function, allowing doctors to measure...

...or. From there, they are steered into a wiggler--a device
that uses an electromagnetic field to shake the electrons, forcing them to release some of their energy in the form of photons. As in a conventional laser, the photons are bounced between two mirrors and then emitted as a coherent beam of light. Howe...
