During cell division metaphase spindles maintain constant length, whereas spindle microtubules continuously flux polewards, requiring addition of tubulin subunits at microtubule plus-ends, polewards translocation of the microtubule lattice, and removal of tubulin subunits from microtubule minus-ends near spindle poles. How these processes are coordinated is unknown. Here, we show that ...

We discuss the impact of different solar neutrino data on the spin-flavor-precession (SFP) mechanism of neutrino conversion. We find that, although detailed solar rates and spectra allow the SFP solution as a subleading effect, the recent KamLAND constraint on the solar antineutrino flux places stronger constraints on this mechanism. Moreover, ...

The spindle checkpoint arrests cells at the metaphase-to-anaphase transition until all chromosomes have properly attached to the mitotic spindle. Checkpoint proteins Mad2p and Mad3p/BubR1p bind and inhibit Cdc20p, an activator for the anaphase-promoting complex (APC). We find that upon spindle checkpoint activation by microtubule inhibitors benomyl or nocodazole, wild-type Saccharomyces ...
