A study published today found that Droplet Digital PCR (ddPCR™) can be used as an accurate and precise method for quality control of next-generation sequencing (NGS) libraries. NGS library QC is essential to optimizing sequencing data yield, thereby increasing efficiency and throughput while lowering cost. The research was published in the in the August issue of Biotechniques.

Small prey fish can grow a bigger 'eye' on their rear fins as a way of distracting predators and dramatically boosting their chances of survival, new scientific research has found.

The human body is full of tiny microorganisms—hundreds to thousands of species of bacteria collectively called the microbiome, which are believed to contribute to a healthy existence. The gastrointestinal (GI) tract—and the colon in particular—is home to the largest concentration and highest diversity of bacterial species. But how do these organisms persist and thrive in a system that is constantly in flux due to foods and fluids moving through it? A team led by California Institute of Technology (Caltech) biologist Sarkis Mazmanian believes it has found the answer, at least in one common group of bacteria: a set of genes that promotes stable microbial colonization of the gut.
