Despite its popularity, the science and regulations sur- rounding microbiome testing are still catching up, high- lighting the need for better standards and oversight.

Regulatory Gaps Plague At-Home Microbiome Tests

A new system that enables researchers to uniquely tag monoclonal antibodies for use in microscopy could help simplify complex imaging studies. 

Fluorescent microscopy of a fly embryo stained with five antibodies. Along the bottom, from left to right, the following colors appear representing unique homeobox (Hox) proteins: Magenta, Green, Yellow, and Red. Vertical cyan stripes appear above this line of colors, and in the middle of the embryo behind these strips is orange staining.
