Characterizing gas flow from aerosol particle injectors
, 2017 A novel methodology for measuring gas flow from small orifices or nozzles into vacuum is presented. It utilizes a high-intensity femtosecond laser pulse to create a plasma within the gas plume produced by the nozzle, which is imaged by a microscope ...

Diversity of Amoeba-Associated Giant Viruses Isolated in Algeria
Diversity, 2020 The discovery of several giant amoeba viruses has opened up a novel area in the field of virology. Despite this, knowledge about ecology of these viruses remains patchy. In this study, we aimed to characterize the diversity of giant viruses in Algeria by

Structural and functional insights into Mimivirus ORFans
BMC Genomics, 2007 Background Mimivirus isolated from A. polyphaga is the largest virus discovered so far. It is unique among all the viruses in having genes related to translation, DNA repair and replication which bear close homology to eukaryotic genes.

Evolution of DNA ligases of Nucleo-Cytoplasmic Large DNA viruses of eukaryotes: a case of hidden complexity [PDF]
, 2009 Background Eukaryotic Nucleo-Cytoplasmic Large DNA Viruses (NCLDV) encode most if not all of the enzymes involved in their DNA replication. It has been inferred that genes for these enzymes were already present in the last common ancestor of the NCLDV ...

Ancestrality and Mosaicism of Giant Viruses Supporting the Definition of the Fourth TRUC of Microbes
Frontiers in Microbiology, 2018 Giant viruses of amoebae were discovered in 2003. Since then, their diversity has greatly expanded. They were suggested to form a fourth branch of life, collectively named ‘TRUC’ (for “Things Resisting Uncompleted Classifications”) alongside Bacteria ...

The Mimivirus L375 Nudix enzyme hydrolyzes the 5' mRNA cap.
PLoS ONE, 2021 The giant Mimivirus is a member of the nucleocytoplasmic large DNA viruses (NCLDV), a group of diverse viruses that contain double-stranded DNA (dsDNA) genomes that replicate primarily in eukaryotic hosts.
