Researchers have made a key breakthrough in how light is used to control time signals from the world’s most precise clocks. The technique marks a crucial step in bringing this technology into everyday life.

Modified components of messenger RNA can cause the protein-production machinery to stall during the process of translation. This might change the protein being made, a finding with implications for vaccines or therapies.

Maternal sensitivity to a hormone produced by the fetus might underlie the risk of severe nausea and vomiting in human pregnancy — a finding that could open up strategies for the treatment of this debilitating condition.

Diverse genomic sequences might boost equity in areas such as health care. Genomic data from Indigenous Australians, shared through a community-consultation framework, aids efforts to boost genetic representation.
