'Vaults' within germ cells offer more than safekeeping

Maternal messenger RNAs (mRNAs), located within the cytoplasm of an immature egg, are crucial for jump starting development. Following fertilization, these mRNAs are passed onto the zygote, the first newly formed cell.

Phage viruses, used to treat antibiotic resistance, gain advantage by cutting off competitors' reproduction ability

Curious bits of DNA tucked inside genomes across all kingdoms of life historically have been disregarded since they don't seem to have a role to play in the competition for survival, or so researchers thought.
