    High-resolution structures of nascent polypeptide chains in complex with the ribosome — the cell’s protein-synthesis machinery — reveal how the ribosome guides protein folding. Ribosomal attachment reduces the entropy (disorder) of the unfolded protein and surrounding water, encouraging ribosome-associated proteins to fold through stable intermediate states not seen in isolated proteins.

    A developing embryo is shaped by forces that are generated by the active contraction of its cells and transmitted across its parts. These forces also allow the embryo to perceive its own form and adjust the proportions of cell types, supporting orderly development in the face of inherent variability and perturbations.
