Catching cancer's spread by watching hemoglobin
...es. If the imaging is fast enough, researchers can capture
snapshots of blood flow in individual vessels. Moving beyond mere imaging, the technique can detect the difference between oxygen-carrying hemoglobin (oxyhemoglobin) and oxygen-lacking hemoglobin (deoxyhemoglobin). This is important for monitoring tu...

images of ventricle layers and analyzed for layer cross-sectional areas. Lactate concentration and net lactate release from cardiac tissue was also examined. Results The researchers found: ventricle strips from males and females h...
DOE JGI sets 'gold standard' for metagenomic data analysis
...eover, you don't have enough sequence from each to capture
an accurate picture of the entire community, so you only get a glimpse of the identities of multiple genomes. All the publications to date have made the assumption that these tools will work as efficiently for metagenomes, "but we really didn't know....

series of snapshots during individual folding reactions to identify multiple phases as the proteins convert from an unordered mishmash into flat sheets, then coil into fibers. "No matter how fast they're moving, we can take pictures of them," say...

time-dependent processes. Results from the model can then be compared to data from the lab, revealing gaps in our understanding of the processes taking place. Researchers can use the model to test hypotheses that would fill in the missing pieces in s...
Bones in motion: Brown scientists to create new 3-D X-ray system
