FAQ

: Communities for students and professionals in biology, biomedical research, and life sciences. Discord servers connect people from high school students to PhD researchers, with LinkedIn groups serving computational biology, bioinformatics, and biotech careers.
: Hive Index lists 4 Biology subreddits on Reddit. Most listings with size data are massive (50%) or huge (25%). We only have a handful of listings so far, so treat these numbers as directional. The main Biology topic page covers every platform we track for this topic.
: Forum is the most common feature (100% of listings).
: All 4 listings on this page are free to join (no paid membership or application gate listed). Access rules can still change on the community side.
: On Hive Index, the default Popular sort surfaces r/biology, r/molecularbiology, r/labrats, and r/marinebiology first. Popularity reflects visitor interest in communities on the site, not a universal quality score. Use the sort menu for Ratings, Largest, or Newest.
: Listings are submitted by community builders and researchers, reviewed for topic relevance, and updated with platform, feature, member, review, and traffic data where available. Member counts are approximate. Popular reflects visitor interest in communities on the site, with richer profiles breaking ties. Ratings, Largest, and Newest use review scores, reported member counts, and listing age instead.
: This page was last updated 5/12/2026, based on the most recent change to the topic or its listings. We refresh entries when communities are submitted, claimed, or reviewed, and we update member counts, features, and traffic data on an ongoing basis.
