  • A new global mode of Earth deformation: seasonal cycle detected
    2017
    Co-Authors: Geoffrey Blewitt, David Lavallée, Peter J. Clarke, Konstantin Nurutdinov
    Abstract:

    We have detected a global mode of Earth deformation that is predicted by theory. Precise positioning of GPS sites distributed worldwide reveals that in February to March the northern hemisphere compresses (and the southern hemisphere expands), such that sites near the North Pole Move downward by 3.0 mm, and sites near the equator are pulled northwards by 1.5 mm. The opposite pattern of deformation occurs in August to September. We identify this pattern as the degree-one spherical harmonic response of an elastic Earth to increased winter loading of soil moisture, snow cover, and atmosphere. Data inversion shows the load moment’s trajectory as a great circle traversing the continents, peaking at 6.9e22 kg m near the North Pole in winter, indicating inter-hemispheric mass exchange of 1.0±0.2e16 kg.

    Abstract:

    We have detected a global mode of Earth deformation that is predicted by theory. Precise positioning of Global Positioning System sites distributed worldwide reveals that during February to March, the Northern Hemisphere compresses (and the Southern Hemisphere expands), such that sites near the North Pole Move downward by 3.0 millimeters, and sites near the equator are pulled northward by 1.5 millimeters. The opposite pattern of deformation occurs during August to September. We identify this pattern as the degree-one spherical harmonic response of an elastic Earth to increased winter loading of soil moisture, snow cover, and atmosphere. Data inversion shows the load moment's trajectory as a great circle traversing the continents, peaking at 6.9 × 1022 kilogram meters near the North Pole in winter, indicating interhemispheric mass exchange of 1.0 × 1016 ± 0.2 × 1016 kilograms.

  • Chromosome congression is promoted by CENP-Q- and CENP-E-dependent pathways
    Journal of Cell Science, 2014
    Co-Authors: James M. Bancroft, Philip Auckland, Catarina P. Samora, Andrew D. Mcainsh
    Abstract:

    A key step of mitosis is the congression of chromosomes to the spindle equator. Congression is driven by at least two distinct mechanisms: (1) kinetochores slide along the microtubule lattice using the plus-end directed CENP-E motor, and (2) kinetochores biorientating near the Pole Move to the equator through microtubule depolymerisation-coupled pulling. Here, we show that CENP-Q – a subunit of the CENP-O complex (comprising CENP-O, CENP-P, CENP-Q and CENP-U) that targets polo-like kinase (Plk1) to kinetochores – is also required for the recruitment of CENP-E to kinetochores. We further reveal a CENP-E recruitment-independent role for CENP-Q in depolymerisation-coupled pulling. Both of these functions are abolished by a single point mutation in CENP-Q (S50A) – a residue that is phosphorylated in vivo. Importantly, the S50A mutant does not affect the loading of Plk1 onto kinetochores and leaves the CENP-O complex intact. Thus, the functions of CENP-Q in CENP-E loading and depolymerisation-coupled pulling are independent from its role in Plk1 recruitment and CENP-O complex stabilisation. Taken together, our data provide evidence that phosphoregulation of CENP-Q plays a central function in coordinating chromosome congression mechanisms.
