Abstract
None:
The placenta is one of the most diverse organs among eutherian mammals, and comparative placentation studies can reveal fundamental processes that support a successful pregnancy. A new study in PLOS Biology uses swine placental organoids and in vivo spatial transcriptomics to uncover key insights into placental cell diversity and evolution.

Improving Translational Accuracy
Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...
