NewsWormlike animals are first amphibians shown to pass microbes to their offspring
Skin-feeding does more than provide nutrients for young caecilians - it also helps the mother pass microbes from her skin and gut down to her young, inoculating them to jump-start a healthy microbiome.

NewsBioengineered yeast devouring agricultural waste could close carbon circle
Researchers report making modified yeast that can feed on a wider range of materials, many of which can be derived from agricultural by-products that we don’t use known as waste biomass.

NewsSquash bugs devour each other’s poo to stock their microbiome
Researchers have found that, to acquire healthy gut bacteria, young squash bugs innately seek out and eat the faeces from older squash bugs.
-
NewsStreptomycetes reveal their arsenal of signalling compounds
Streptomyces bacteria produce a group of signalling molecules that trigger a variety of processes, a new study shows.
