Babies get their earliest “vaccines” from their mothers, in the form of blood proteins that pass through the placenta in the third trimester.

They've shown a part of the body known to recycle proteins has a secret mode that can spew out an arsenal of bacteria-killing chemicals.

Other human remains found elsewhere in Herculaneum had iron oxide deposits in the skull, suggesting that the fluids in the skull were vaporized by the heat, leaving only traces of degraded heme proteins.

Meat products will initially be replaced by existing alternative protein products like plant-based burgers, but in later years it expects us to start eating more "alternative proteins".

Researchers relied on a technique called meta-proteome analysis, which studies the interaction of genes and proteins within an organism, to reach their conclusion.
