Virus evolution : the emergence of new ideas (and re-emergence of old ones) [PDF]

open access: yesarXiv, 2006
Reputed intractable, the question of the origin of viruses has long been neglected. In the modern literature 'Virus evolution' has come to refer to study more akin to population genetics, such as the world-wide scrutiny on new polymorphisms appearing daily in the H5N1 avian flu virus [1], than to the fundamental interrogation: where do viruses come ...

Number of natively unfolded proteins scales with genome size [PDF]

open access: yesarXiv, 2008
Natively unfolded proteins exist as an ensemble of flexible conformations lacking a well defined tertiary structure along a large portion of their polypeptide chain. Despite the absence of a stable configuration, they are involved in important cellular processes. In this work we used from three indicators of folding status, derived from the analysis of

Leakage risk assessment system for salt cavern hydrogen storage

open access: yesDeep Underground Science and Engineering, EarlyView.
Establishment of a leakage risk evaluation system for salt cavern hydrogen storage reservoirs using the entropy weight method plus two‐dimensional cloud modeling approach. Abstract Salt cavern hydrogen storage (SCHS) is an important component of large‐scale underground hydrogen storage, with advantages such as large hydrogen storage capacity and ...

MinD2 modulates cell shape and motility in the archaeon Haloferax volcanii

open access: yesFrontiers in Microbiology
In bacteria and archaea, proteins of the ParA/MinD family of ATPases regulate the spatiotemporal organization of various cellular cargoes, including cell division proteins, motility structures, chemotaxis systems, and chromosomes.
