Cell chemistry illuminated by laser light

Raman microspectroscopy is a laboratory technique to produce molecular fingerprints of materials and biological specimens. However, to date fluorescence has interfered with effective application of this technique and limited ...

Lost frog DNA revived

As part of a "Lazarus Project" to try to bring the Australian gastric-brooding frog back from extinction a UNSW-led team has succeeded in producing early stage cloned embryos containing the DNA of the frog, which died out ...

Live pathogens: Rapid detection technique developed

(Phys.org)—Los Alamos researchers have developed a better technique for quick detection of live pathogens in the field. Identification of viable bacteria in a complex environment is scientifically challenging. Current detection ...

Study suggests carbon nanotubes may protect DNA from oxidation

(Phys.org)—Researchers at the National Institute of Standards and Technology (NIST) have provided evidence in the laboratory that single-wall carbon nanotubes (SWCNTs) may help protect DNA molecules from damage by oxidation. ...
