Correlation between mutation rate and genome size in riboviruses: mutation rate of bacteriophage Qβ.
2013
Abstract Genome sizes and mutation rates covary across all domains of life. In unicellular organisms and DNA viruses, they show an inverse relationship known as Drake’s rule. However, it is still unclear whether a similar relationship exists between genome sizes and mutation rates in RNA genomes. Coronaviruses, the RNA viruses with the largest genomes (∼30 kb), encode a proofreading 3′ exonuclease that allows them to increase replication fidelity. However, it is unknown whether, conversely, the RNA viruses with the smallest genomes tend to show particularly high mutation rates. To test this, we measured the mutation rate of bacteriophage Qβ, a 4.2-kb levivirus. Amber reversion-based Luria–D…
Combination of acoustic levitation with small angle scattering techniques and synchrotron radiation circular dichroism. Application to the study of p…
2016
Abstract Background The acoustic levitation technique is a useful sample handling method for small solid and liquids samples, suspended in air by means of an ultrasonic field. This method was previously used at synchrotron sources for studying pharmaceutical liquids and protein solutions using x-ray diffraction and small angle x-ray scattering (SAXS). Methods In this work we combined for the first time this containerless method with small angle neutron scattering (SANS) and synchrotron radiation circular dichroism (SRCD) to study the structural behavior of proteins in solutions during the water evaporation. SANS results are also compared with SAXS experiments. Results The aggregation behavi…
The relationship between body and screen in Studio Azzurro’s performances since the 1980s until today
2018
Studio Azzurro is an Italian group that has been working with different performative languages since the 1980s: video installations, theater, video art, cinema, interactive installations, interactive museums. In all these artistic experiences Studio Azzurro has never worked using the languages handed down by tradition, but has always experimented by mixing them with new technologies. The work they have conducted in theater is particular, because the use of new technologies has transformed the concept of theater and has opened the way for the development of new performative forms such as digital or technological theater. In what follows, we will study the relationship between body and screen…
Remote but Connected : Lapland as a Scene of Transnational Crime in Ivalo
2021
Set in a small town in the north of Finland, the crime TV series Ivalo (Arctic Circle, Finland, 2018) exemplifies the fascination of Nordic Noir with ‘remote’ locations as scenes of transnational crime. The plot seems to forebode the corona pandemic, portraying the spread of a life-threatening ‘Yemenite virus’ developed as a biological weapon from the Balkans to Lapland. In this article, I analyze how the virus narrative allows the series to bring new perspectives on Nordic Noir. The narrative emphasizes international connections while creating representations of places that can be characterized as both translocal (Greiner and Sakdapolrak 2013) and glocal (Robertson 2012). Because of its fa…
Climate Change in Literature, Television and Film from Norway
2020
Environmental and climatic change has become a frequent motif in contemporary Norwegian literature, television and film, and Norway has the worldwide first organization of writers committed to climate action (The Norwegian Writers’ Climate Campaign, founded in 2013). In this article, we argue that Norwegian climate change fiction and related works draw on elements that relate to specific national and/or Nordic cultural, societal and historical features, and that these elements give these works their distinct identity. We focus on four such features: (1) notions of “Nordicity”; (2) an (imagined) intimate connection between Norwegianness and nature, often seen as a typical element of Norwegia…

The SMILETRAP (Stockholm-Mainz-Ion-LEvitation-TRAP) facility
1996
Described in this paper is an experimental facility which measures atomic masses by using multiply charged ions from an electron beam ion source. The ions are injected into a Penning trap and the cyclotron frequencies measured. A precision of 2×10−9 has been reached using highly charged carbon, nitrogen, oxygen and neon.
