These Bald Eagles fly the wrong way every year and stun scientists

Birds of a feather do not always flock together, despite the adage. A new study in the Journal of Raptor Research describes how Bald Eagles (Haliaeetus leucocephalus) from Arizona are making unusual journeys by flying north instead of south, unlike most migratory birds in temperate regions. The paper, titled “Northward Migrations of Nonbreeding Bald Eagles […]

Perinuclear non-centrosomal microtubules direct nuclei dispersion during epithelial morphogenesis

As cells contract and reshape to enable tissue morphogenesis, their own internal structures can constrain these behaviors. In the Drosophila germband, the uncrowding of nuclei away from an initially common plane is required for efficient cell intercalation and extension. Here, we find that a centrosomally derived microtubule network transitions into non-centrosomal arrays that are deeply […]
