Structural evidence for elastic tethers connecting separating chromosomes in crane-fly spermatocytes

open access: yesLife Science Alliance, 2023
Correlative live imaging with electron tomography provides evidence that physical filamentous connections extend between separating telomeres at all stages of anaphase.

Blocking Protein Phosphatase 1 [PP1] Prevents Loss of Tether Elasticity in Anaphase Crane-Fly Spermatocytes

open access: yesFrontiers in Molecular Biosciences, 2021
In normal anaphase cells, telomeres of each separating chromosome pair are connected to each other by tethers. Tethers are elastic at the start of anaphase: arm fragments cut from anaphase chromosomes in early anaphase move across the equator to the ...

Hydrologically driven ecosystem processes determine the distribution and persistence of ecosystem-specialist predators under climate change. [PDF]

open access: yesNat Commun, 2015
Climate change has the capacity to alter physical and biological ecosystem processes, jeopardising the survival of associated species. This is a particular concern in cool, wet northern peatlands that could experience warmer, drier conditions.

Bacillus sphaericus mosquito pathogens in the aquatic environment

open access: yesMemorias do Instituto Oswaldo Cruz, 1995
The fate of Bacillus sphaericus spores in the aquatic environment was investigated by suspending spores in dialysis bags in fresh and seawater. Spore viability was lost more rapidly in seawater. Neither B. sphaericus nor B. thuringiensis israelensis (B.t.

Elastic Tethers Between Separating Anaphase Chromosomes Regulate the Poleward Speeds of the Attached Chromosomes in Crane-Fly Spermatocytes

open access: yesFrontiers in Molecular Biosciences, 2020
Elastic “tethers” connect separating anaphase chromosomes in most (or all) animal cells. We tested whether tethers are involved in coordinating movements of separating anaphase chromosomes in crane-fly spermatocytes.

Insights into Sensitivity of Wing Shape and Kinematic Parameters Relative to Aerodynamic Performance of Flapping Wing Nano Air Vehicles

open access: yesDrones, 2019
In this work, seven wings inspired from insects’ wings, including those inspired by the bumblebee, cicada, cranefly, fruitfly, hawkmoth, honeybee, and twisted parasite, are patterned and analyzed in FlapSim software in forward and hovering flight ...
