studies done using arsenic trioxide on a limited number of newly diagnosed patients, but we are the first group to suggest that it is acceptable as a first-line treatment," said Dr. Ghavamzadeh. "The results are comparable to ATRA with chemotherapy a...

Far more men than women favor routine paternity testing at birth

specialists to do the job, biologists are looking for high-throughput tools that can rapidly and accurately identify individuals from known species and from an entirely new species. In the open access journal, PLoS Biology, Paul Hebert and colleagues...
Hidden diversity: DNA 'barcoding' reveals a common butterfly is actually 10 different species
...If the specimens in question differ by more than a few
percent in their base pairs of DNA in this gene, it is likely that they have come from different populations. Paul Hebert and Erin Penton at Guelph were able to extract the necessary DNA from 484 adult butterflies deposited at the Smithsonian - all r...
