Helping Those with Dysthymic Depression
Clinical depression is an epidemic that is diagnosed in over 9 million Americans each year–a marginal amount of the real number it affects, since most Americans never seek medical aid for clinical depression.

A better test to detect DNA for diagnosing disease, investigating crimes
Researchers in Singapore are reporting development of a new electronic sensor that shows promise as a faster, less expensive, and more practical alternative than tests now used to detect DNA.

Comparing sequences without using alignments: application to HIV/SIV subtyping
In general, the construction of trees is based on sequence alignments. This procedure, however, leads to loss of informationwhen parts of sequence alignments (for instance ambiguous regions) are deleted before tree building.

Real-time phase-contrast x-ray imaging: a new technique for the study of animal form and function
This technique takes advantage of partially-coherent x-rays and diffraction to enable clear visualization of internal soft tissue not viewable via conventional absorption radiography.

Fast and non-invasive PCR sexing of primates: apes, Old World monkeys, New World monkeys and Strepsirrhines
One of the key tools for determining the social structure of wild and endangered primates is the ability to sex DNA from small amounts of non-invasive samples that are likely to include highly degraded DNA.
