Philadelphia, PA, December 12, 2013 – Researchers have developed a new assay for rapid and sensitive detection of Chlamydia trachomatis, the most common sexually transmitted infection (STI) in humans. This procedure takes less than 20 minutes and can be easily performed at the point of care (POC) during the patient's visit, reports The Journal of Molecular Diagnostics. read more
Interplay between genes and the environment has been pondered at least since the phrase "nature versus nurture" was coined in the mid-1800s. But until the arrival of modern genomic sequencing tools, it was hard to measure the extent that the environment had on a species' genetic makeup. read more
