Aurora B puts chromosomes in their place mall molecule inhibitors of Aurora B activity, characterized by Hauf et al. (page 281) and Ditchfield et al. (page 267), reveal that the mammalian kinase and its budding yeast counterpart, Ipl1, have similar functions. Without Aurora B, mistakes in kinetochore–chromosome interactions go uncorrected. Early evidence of a function for the Aurora family in c...
متن کاملLymphocytes shrink to stay fit
In response to an infection, proinfl ammatory cytokines stimulate lymphocytes to take up nutrients so that they can proliferate and mount an immune response. Once the infection is cleared, however, cytokine levels decline and the lymphocytes’ nutrient supply is abruptly cut off. Most of the cells quickly die by apoptosis, but a small fraction survive and differentiate into longlived memory cell...
متن کاملHow chromosomes shrink to fit
Cells in an early embryo need to downsize their DNA. Ladouceur et al. show that a cell’s size and the size of its nucleus determine how small its chromosomes become (1). Like someone who’s moved from a house to an apartment, cells in an early embryo run into space limitations. The embryo remains the same size for its fi rst few divisions, so the cells have to become much smaller, shrinking by a...

متن کاملGroup to Group Commitments Do Not Shrink
We investigate commitment schemes whose messages, keys, commitments, and decommitments are elements of bilinear groups, and whose openings are verified by pairing product equations. Such commitments facilitate efficient zero-knowledge proofs of knowledge of a correct opening. We show two lower bounds on such schemes: a commitment cannot be shorter than the message and verifying the opening in a...
