The Nature Explorers Chiricahua Part 3 of 12

submitted by: thenatureexplorers

Chiricahua is a "Sky Island" region that supports a variety of wildlife, some of which are more commonly thought of as denizens of subtropical habitats in Mexico or Central America. Even in February with snow and temperatures as low as -10°F we still found a cornucopia of nature, turkeys, woodpeckers, centipedes, pines, yuccas, agaves, and more.

biosights: September 2, 2013 - Shrinking microtubules pull the centrosome into place

submitted by: JCB
When a T cell encounters a target antigen-presenting cell, it moves its centrosome to the immunological synapse that connects the two cells. Yi et al. reveal that centrosome repositioning is a biphasic process driven by the dynein-dependent capture and depolymerization of microtubules. This biosights episode presents the paper by Yi et al. from the September 2, 2013, issue of The Journal of Cell Biology and includes an interview with senior author John Hammer (NHLBI, Bethesda, MD).

biosights: August 5, 2013 - Epithelia restored by healing waves

submitted by: JCB
Epithelial cells around the edge of a wound assemble an actomyosin cable that constricts to draw the wound closed, but the events that precede cable formation are largely unknown. Antunes et al. reveal that wounding induces a wave of actomyosin assembly and cell constriction that flows toward the wound edge to promote cable assembly and tissue repair. This biosights episode presents the paper by Antunes et al. from the July 22, 2013, issue of The Journal of Cell Biology and includes an...
