DOE JGI sets 'gold standard' for metagenomic data analysis

...sume that the sequence queried belongs to the same group of organisms. Other methods use intrinsic features of the sequence, such as oligonucleotide frequencies. Patterns of these features help to discriminate between the possible groups of organisms that contributed the sequence. Several more methods...

Atypical antipsychotics, a newer group of prescription medications used to treat psychiatric conditions, have fewer side effects than the older antipsychotics, but several still induce weight gain and diabetes. Schizophrenic patients were found to have lower levels of the lipids used t...
