Lifestyle is a threat to gut bacteria: Ötzi proves it, study shows


The evolution of dietary and hygienic habits in Western countries is associated with a decrease in the bacteria that help in digestion. These very bacteria were also found in the Iceman, who lived 5300 years ago, and are still present in non-Westernized populations in various parts of the world. The depletion of the microbiome may be associated with the increased prevalence, in Western countries, of complex conditions like allergies, autoimmune and gastrointestinal diseases, obesity.

Ants inhibit at least 14 different plant diseases

New research shows that ants inhibit at least 14 different plant diseases. The small insects secrete antibiotics from glands in the body. On their legs and body, they also host colonies of bacteria that secrete antibiotics. It is probably these substances that inhibit a number of different diseases and researchers now hope to find biological pesticides that may conquer resistant plant diseases.

Many cooks don't spoil the broth: Manifold symbionts prepare the host for any eventuality

Deep-sea mussels, which rely on symbiotic bacteria for food, harbor a surprisingly high diversity of these bacterial 'cooks': Up to 16 different bacterial strains live in the mussel's gills, each with its own abilities and strengths. Thanks to this diversity, the mussel is prepared for all eventualities, researchers report.
