Impact of test methodology on the efficacy of triethylene glycol (Grignard Pure) against bacteriophage MS2.

The COVID-19 pandemic has raised interest in using chemical air treatments as part of a strategy to reduce the risk of disease transmission, but more information is needed to characterize their efficacy at scales translatable to applied settings and to develop standardized test methods for characterizing the performance of these products. Grignard Pure, a triethylene glycol (TEG) active ingredient air treatment, was evaluated using two different test protocols in a large bioaerosol test chamber and observed to inactivate bacteriophage MS2 in air (up to 99.9% at 90 min) and on surfaces (up to 99% at 90 min) at a concentration of approximately 1.

On the Role of Speech In Psychoanalysis: Revisiting Lacan's "Function and Field".

A number of underutilized concepts in Lacan's "Function and Field of Language and Speech in Psychoanalysis" are examined with an eye to rendering them accessible and practicable to analysts from outside the Lacanian tradition. The concepts of empty and full speech are discussed, along with the notions of the subject of the unconscious, and speaking as itself a mode of intersubjectivity. Attention is afforded the future-oriented mode of psychic temporality that Lacan argues pertains to psychoanalytic practice (that of the future anterior tense, the standpoint from which analysands situate themselves in respect of what they "will have been").

The pandemic veneer: COVID-19 research as a mobilisation of collective intelligence by the global research community.

The global research community responded with speed and at scale to the emergence of COVID-19, with around 4.6% of all research outputs in 2020 related to the pandemic. That share almost doubled through 2021, to reach 8.
