In today’s Microbiome Digest the first interesting study comes not from bacteria but from virus domain. Examining the genomes within a sample from a wastewater treatment plant in Austria, Schulz et al. assembled a previously undiscovered giant virus genome with more genes encoding components of the protein translation machinery than in other giant viruses. The second highlighted  study introduces new oleaginous microalga as a new potential source of compounds for biotechnological applications.

Today’s digest features interesting review articles on the role of microbiome in health and disease, heart failure, and how the respiratory tract microbiota act as gatekeepers to respiratory health. Also, we have original research articles on the response of bacterial communities in oil-contaminated marine waters to addition of chemical and biological dispersants. Also, a very fascinating article in Harvard Business review on the gender bias against junior female scientists. Not surprising!! Enjoy.

Circadian clocks are ubiquitous timing systems that induce rhythms of biological activities in synchrony with night and day.In the first highlighted paper the authors present the structural basis of the day-night transition in a cyanobacterial circadian clock. The second highlighted paper evaluated the effects of antibiotic treatment on the honeybee gut microbiome. The authors found that exposure to antibiotics significantly alters the honeybee gut microbial community structure and leads to decreased survival.
