Hearing voices among Russian patients with schizophrenia.

There has been relatively little work which systematically examines whether the content of hallucinations in individuals diagnosed with schizophrenia varies by cultural context. The work that exists finds that it does. The present project explores the way auditory hallucinations, or "voices," manifest in a Russian cultural context.

Non-destructive sampling of ancient insect DNA.

Background: A major challenge for ancient DNA (aDNA) studies on insect remains is that sampling procedures involve at least partial destruction of the specimens. A recent extraction protocol reveals the possibility of obtaining DNA from past insect remains without causing visual morphological damage. We test the applicability of this protocol on historic museum beetle specimens dating back to AD 1820 and on ancient beetle chitin remains from permafrost (permanently frozen soil) dating back more than 47,000 years.
