On 11 March 2020, the World Health Organization declared SARS-CoV-2 and its associated disease, COVID-19, a global pandemic. Across the world, governments took action to slow the spread and hospitals rushed to accommodate an influx of patients with this highly infectious and lethal disease. The urology departments in Ann Arbor, Michigan, USA, and Herlev and Gentofte, Copenhagen, Denmark — which are linked by the pre-existing CopMich Collaborative — had to respond with massive changes to the organization, staffing and workload of their teams. In this Viewpoint, authors from different urological subspecialties and at different career stages reflect on their experiences during the pandemic. Although their countries’ responses to the COVID-19 pandemic differed radically, the similarities between the responses in Copenhagen and Michigan demonstrate the universal characteristics of medicine and the value of teamwork, flexibility and collaboration.

A global network of researchers was formed to investigate the role of human genetics in SARS-CoV-2 infection and COVID-19 severity; this paper reports 13 genome-wide significant loci and potentially actionable mechanisms in response to infection.

A meta-analysis of genome-wide association studies of type 2 diabetes (T2D) identifies more than 600 T2D-associated loci; integrating physiological trait and single-cell chromatin accessibility data at these loci sheds light on heterogeneity within the T2D phenotype.

Carnot efficiency is the highest theoretically possible efficiency that a heat engine can have. Verley et al.use the fluctuation theorem to show that the Carnot value is the least likely efficiency in the long time limit.

Eye movements during scene viewing are tied to grid-like codes in the entorhinal cortex. Grid signals are specific to later remembered scenes, covary with activity in visuo-oculomotor regions, and are linked to weaker memory.

Understanding the growth dynamics of GBMs can help expand therapeutic options. Here, authors use a cross-species computational approach to compare GBM cells to healthy neural stem cells, identifying predictors and modulators of tumour growth, including the Wnt antagonist, SFRP1, which stalls growth in preclinical xenograft models.

Genome-wide association analyses identify new risk loci for heart failure and its subtypes, extending understanding of the underlying biological pathways and disease mechanisms.

Understanding the underlying pathophysiology of obesity can help prevent this condition. Here, the authors perform a GWAS of BMI in diverse ancestries, finding four missense variants in FRS3 that affect BMI.

Analysing camera-trap data of 163 mammal species before and after the onset of COVID-19 lockdowns, the authors show that responses to human activity are dependent on the degree to which the landscape is modified by humans, with carnivores being especially sensitive.

Recently, the first orally-administered ultra-long acting insulin was shown to have clinical efficacy. Here, the authors report the molecular engineering, as well as the biological and pharmacological properties of these insulin analogues.

Single-cell methods record molecule expressions of cells in a given tissue, but understanding interactions between cells remains challenging. Here the authors show by applying systems biology and machine learning approaches that they can infer and analyze cell-cell communication networks in an easily interpretable way.

Single molecule real-time DNA sequencing allows genome-wide identification of DNA methylation patterns. Here, Jensen et al. present a high-throughput method that allows rapid coupling of DNA methylation patterns with their corresponding methyltransferase genes in bacteria.
