— A new race for water is rippling through the drought-scorched heartland, pitting farmers against oil and gas interests, driven by new drilling techniques that use powerful streams of water, sand and chemicals to crack the ground and release stores of oil and gas.
Classical taxonomy, which uses morphological features to identify species, is being replaced by DNA bar-coding techniques that use genes to tell previously known species apart.
These can be analysed by a technique that uses fluorescence to read the sequences of the letters that compose the molecules.
The DNA molecules on the balls can then be analysed by a technique that uses fluorescence to read the sequences of the bases of which they are composed.Once the sequences of the DNA fragments have been obtained, the overlaps between them can be used to stitch them together into a complete message, as has been done for many other species.
By using a technique that uses a laser to exert forces on an individual DNA molecule, Suksombat et al. unraveled DNA from a single SSB protein.
FFA were measured by an enzymatic technique that used acylCoA oxidase (Wako Diagnostics, Wako Chemicals, USA , Inc (inter-assay CV of <1.5%).
Last year, Mr. Diggs added to its holdings by developing a glazing technique that uses vinegar and is inspired by the Japanese philosophical tradition of wabi-sabi, making beauty out of imperfection.
Not just any old periodic table, but the most photographically breathtaking version ever created, encased in sturdy plastic and enlivened by "lenticular technology," the technique that uses linear lens elements laminated over a specially processed image to create a convincing 3D effect.
Digesta samples were collected from eight different gastrointestinal segments of each animal and the bacterial population was analysed by a PCR-RFLP technique that uses 16S rDNA gene sequences.
This can be done by ray tracing, a rendering technique that uses basic optical laws of reflection and refraction.
