Actin cables and comet tails organize mitochondrial networks in mitosis [PDF]

open access: yesNature, 2021
Symmetric cell division requires the even partitioning of genetic information and cytoplasmic contents between daughter cells. Whereas the mechanisms coordinating the segregation of the genome are well known, the processes that ensure organelle ...

Electron tomography and simulation of baculovirus actin comet tails support a tethered filament model of pathogen propulsion. [PDF]

open access: yesPLoS Biology, 2014
Several pathogens induce propulsive actin comet tails in cells they invade to disseminate their infection. They achieve this by recruiting factors for actin nucleation, the Arp2/3 complex, and polymerization regulators from the host cytoplasm.

Monte Carlo Models of Comet Dust Tails Observed from the Ground

open access: yesUniverse, 2022
Dust particles leaving the comet nucleus surface are entrained by the gas within the first few nuclear radius distances and are subjected to a complex hydrodynamical environment.

A Disintegrating Rocky Planet with Prominent Comet-like Tails around a Bright Star [PDF]

open access: yesThe Astrophysical Journal Letters
We report the discovery of BD+05 4868 Ab, a transiting exoplanet orbiting a bright ( V = 10.16) K-dwarf (TIC 466376085) with a period of 1.27 days.

Yogi Berra, Forrest Gump, and the discovery of Listeria actin comet tails. [PDF]

open access: yesMol Biol Cell, 2012
In 1988, eminent cell biologist Lew Tilney and newly appointed Assistant Professor of Microbiology Dan Portnoy met at a picnic and initiated a collaboration that led to a groundbreaking paper published in Journal of Cell Biology entitled “Actin filaments

Choosing orientation: influence of cargo geometry and ActA polarization on actin comet tails. [PDF]

open access: yesMol Biol Cell, 2012
ETOC: We reconstitute actin-based motility using ellipsoidal particles mimicking the rod shape of Listeria monocytogenes and systematically analyze bead motile behaviors.

Statistical Analysis of Comet Disconnection Events Using STEREO HI and a Data-assimilative Solar Wind Model

open access: yesThe Astrophysical Journal
Comets tails can reveal information about the local solar wind conditions. They can exhibit various signatures of interactions with the solar wind including bending, developing kinks, and sometimes undergoing tail disconnections.

Dendritic organization of actin comet tails [PDF]

open access: yesCurrent Biology, 2001
Polymerization of actin filaments is necessary for both protrusion of the leading edge of crawling cells and propulsion of certain intracellular pathogens, and it is sufficient for generating force for bacterial motility in vitro. Motile intracellular pathogens are associated with actin-rich comet tails containing many of the same molecular components ...
