00:45 Inert ant pupae produce a previously unobserved fluid

Ant larvae metamorphose into adults by pupating. It was assumed that these inert pupae don’t play a role in the wider ant colony, but a team of researchers have found that they actually secrete a fluid that is consumed by both adult ants and larvae. This fluid is rich in proteins and metabolites, and appears to be an important source of larval nutrition. These secretions have now been seen in the pupae of multiple ant species, suggesting it is an evolutionary ancient behaviour.

We discuss some highlights from the Nature Briefing. This time, how analysing mosquito blood meals could reveal evidence of infection in people and animals, and how prolific data generation has driven the need for new metric unit prefixes.
