BACKGROUND: The coronavirus disease 19 (COVID-19) pandemic has spread globally, causing extensive illness and mortality. In advance of effective antiviral therapies, countries have applied different public health strategies to control spread and manage healthcare need. Sweden has taken a unique approach of not implementing strict closures, instead urging personal responsibility. We analyze the res

Despite slow ongoing progress in increasing the representation of women in academia, women remain significantly under-represented at senior levels, in particular in the natural sciences and engineering. Not infrequently, this is downplayed by bringing forth arguments such as inherent biological differences between genders, that current policies are adequate to address the issue, or by deflecting t

Characterizing the adaptive landscapes that encompass the emergence of novel enzyme functions can provide molecular insights into both enzymatic and evolutionary mechanisms. Here, we combine ancestral protein reconstruction with biochemical, structural and mutational analyses to characterize the functional evolution of methyl-parathion hydrolase (MPH), an organophosphate-degrading enzyme. We ident

This study explores Buddhist monks’ views on the religion-science relationship in contemporary China. Drawing on survey data, interviews with monks, and participant observation within Shaolin Temple – famous for its antiquity and its export of Shaolin Kungfu – we discern and theoretically account for two forms of ‘non-conflict,’ between science and religion, that shape monks’ mental lives. One gro

Ni-based superalloys, essential for high-temperature applications, derive strength from coherent second-order precipitates that impede dislocation motion through coherency misfit and elastic mismatch. This study employs multi-component phase-field crystal (PFC) simulations to explore the elastic deformation of such precipitates. Using a binary ordered square structure for the precipitate and a sin

Background: Peripartum asphyxia affects three to five per 1000 live births, with moderate or severe hypoxic ischemic encephalopathy (HIE) occurring in 0.5 to 1 per 1000 live births, and is associated with high mortality and morbidity. Therapeutic hypothermia is an effective treatment, but alternative therapies such as acupuncture are also used. Objectives: To determine the benefits and harms of ac

Arbetsgivarens intresse av en drogfri arbetsplats måste balanseras mot arbetstagarens rätt till personlig integritet vid drogtester, vilket skapar en komplex juridisk fråga. Uppsatsen undersöker processen stegvis för genomförandet av drogtester inom den privata sektorn ur en rättslig synvinkel. Från arbetsgivarens perspektiv granskas när och hur drogtester får utföras samt de rättsliga konsekvenThe employer’s interest in maintaining a drug-free workplace must be balanced against the employee’s right to personal integrity in the context of drug testing, creating a complex legal issue. This thesis examines the step-by-step process of conducting drug tests within the private sector from a legal perspective. From the employer’s standpoint, the study analyzes when and how drug tests may be

The development of replacing human organs with those from genetically modified pigs holds immense potential for alleviating the shortage of organs necessary for patients in need of transplants. This medical advancement is also accompanied by significant social changes, including the emergence of a bioeconomy, new modes of biotechnology governance, altered human-animal relations and increased publi

Recent years have witnessed an explosion of interest in understanding the role of conformational dynamics both in the evolution of new enzymatic activities from existing enzymes and in facilitating the emergence of enzymatic activity de novo on scaffolds that were previously non-catalytic. There are also an increasing number of examples in the literature of targeted engineering of conformational d

Phosphate and sulfate esters have important roles in regulating cellular processes. However, while there has been substantial experimental and computational investigation of the mechanisms and the transition states involved in phosphate ester hydrolysis, there is far less work on sulfate ester hydrolysis. Here, we report a detailed computational study of the alkaline hydrolysis of diaryl sulfate d

GTP hydrolysis is central to biology, being involved in regulating a wide range of cellular processes. However, the mechanisms by which GTPases hydrolyze this critical reaction remain controversial, with multiple mechanistic possibilities having been proposed based on analysis of experimental and computational data. In this mini-review, we discuss advances in our understanding of biological GTP hy

The ubiquity of phospho-ligands suggests that phosphate binding emerged at the earliest stage of protein evolution. To evaluate this hypothesis and unravel its details, we identified all phosphate-binding protein lineages in the Evolutionary Classification of Protein Domains database. We found at least 250 independent evolutionary lineages that bind small molecule cofactors and metabolites with ph

Evolutionary trajectories are deemed largely irreversible. In a newly diverged protein, reversion of mutations that led to the functional switch typically results in loss of both the new and the ancestral functions. Nonetheless, evolutionary transitions where reversions are viable have also been described. The structural and mechanistic causes of reversion compatibility versus incompatibility ther

Conceived as a catalogue and an artist’s book, the publication was made on occasion of the eponymous 2022 exhibition at Indipendenza Roma. Deeply responsive to the space, the exhibition brought together works by Louise Lawler and Fredrik Værslev to explore the tension between an artwork and its surrounding architectural context, spurring questions of taste, value, function, and decoration.

Structural and biochemical studies on diverse enzymes have highlighted the importance of ligand-gated conformational changes in enzyme catalysis, where the intrinsic binding energy of the common phosphoryl group of their substrates is used to drive energetically unfavorable conformational changes in catalytic loops, from inactive open to catalytically competent closed conformations. However, compu
