TL;DR: Preterm infants are vulnerable to suboptimal early nutrition in terms of their cognitive performance—notably, language based skills—at 7 1/2 - 8 years, when cognitive scores are highly predictive of adult ones, and cognitive function, notably in males, may be permanently impaired bySuboptimal neonatal nutrition.
Abstract: Objectives: To determine whether perinatal nutrition influences cognitive function at 7 1/2 - 8 years in children born preterm. Design: Randomised, blinded nutritional intervention trial. Blinded follow up at 7 1/2 - 8 years. Setting: Intervention phase in two neonatal units; follow up in a clinic or school setting. Subjects: 424 preterm infants who weighed under 1850 g at birth; 360 of those who survived were tested at 7 1/2 - 8 years. Interventions: Standard infant formula versus nutrient enriched preterm formula randomly assigned as sole diet (trial A) or supplements to maternal milk (trial B) fed for a mean of 1 month. Main outcome measures: Intelligence quotient (IQ) at 7 1/2 - 8 years with abbreviated Weschler intelligence scale for children (revised). Results: There was a major sex difference in the impact of diet. At 7 1/2 - 8 years boys previously fed standard versus preterm formula as sole diet had a 12.2 point disadvantage (95% confidence interval 3.7 to 20.6; P Conclusions: Preterm infants are vulnerable to suboptimal early nutrition in terms of their cognitive performance—notably, language based skills—at 7 1/2 - 8 years, when cognitive scores are highly predictive of adult ones. Our data on cerebral palsy generate a new hypothesis that suboptimal nutritional management during a critical or plastic early period of rapid brain growth could impair functional compensation in those sustaining an earlier brain insult. Cognitive function, notably in males, may be permanently impaired by suboptimal neonatal nutrition.

TL;DR: The results indicate that, by using effective interventions, some countries could control the epidemic while avoiding stay-at-home orders, and this model accounts for uncertainty in key epidemiological parameters, such as the average delay from infection to death.
Abstract: Governments are attempting to control the COVID-19 pandemic with nonpharmaceutical interventions (NPIs). However, the effectiveness of different NPIs at reducing transmission is poorly understood. We gathered chronological data on the implementation of NPIs for several European, and other, countries between January and the end of May 2020. We estimate the effectiveness of NPIs, ranging from limiting gathering sizes, business closures, and closure of educational institutions to stay-at-home orders. To do so, we used a Bayesian hierarchical model that links NPI implementation dates to national case and death counts and supported the results with extensive empirical validation. Closing all educational institutions, limiting gatherings to 10 people or less, and closing face-to-face businesses each reduced transmission considerably. The additional effect of stay-at-home orders was comparatively small.

TL;DR: Investigation of time trends in mortality from cervical cancer in Denmark, Finland, Iceland, Norway, and Sweden since the early 1950s supports the conclusion that organised screening programmes have had a major impact on the reduction in mortality in the Nordic countries.

TL;DR: Watson and Crick proposed that plant viruses consistently took one of two shapes because the two chemical components of which they were made up, ribonucleic acid surrounded by a large number of identical protein subunits, were assembled according to a general plan that was determined by "symmetry elements".
Abstract: Renewing their collaboration during Watson's return to the Cavendish laboratory in the fall of 1955, Watson and Crick
in this article laid out a theory for explaining why all plant viruses whose structure had been studied up to that time were
very similar in shape, either rod-shaped (cylindrical) or spherical. In developing their theory they once again benefited
from their complementary expertise, namely Crick's extensive knowledge of X-ray crystallography and Watson's previous
studies with tobacco mosaic virus and ribonucleic acid. They proposed that plant viruses consistently took one of two shapes
because the two chemical components of which they were made up, ribonucleic acid surrounded by a large number of identical
protein subunits, were assembled according to a general plan that was determined by "symmetry elements," structural
requirements imposed by the shape of each protein subunit and by the angles of the bonds they formed with the ribonucleic
acid core.

TL;DR: The most successful interventions could increase walking among targeted participants by up to 30-60 minutes a week on average, at least in the short term, from a perspective of improving population health.
Abstract: Objective To assess the effects of interventions to promote walking in individuals and populations. Design Systematic review. Data sources Published and unpublished reports in any language identified by searching 25 electronic databases, by searching websites, reference lists, and existing systematic reviews, and by contacting experts. Review methods Systematic search for and appraisal of controlled before and after studies of the effects of any type of intervention on how much people walk, the distribution of effects on walking between social groups, and any associated effects on overall physical activity, fitness, risk factors for disease, health, and wellbeing. Results We included 19 randomised controlled trials and 29 non-randomised controlled studies. Interventions tailored to people9s needs, targeted at the most sedentary or at those most motivated to change, and delivered either at the level of the individual (brief advice, supported use of pedometers, telecommunications) or household (individualised marketing) or through groups, can encourage people to walk more, although the sustainability, generalisability, and clinical benefits of many of these approaches are uncertain. Evidence for the effectiveness of interventions applied to workplaces, schools, communities, or areas typically depends on isolated studies or subgroup analysis. Conclusions The most successful interventions could increase walking among targeted participants by up to 30-60 minutes a week on average, at least in the short term. From a perspective of improving population health, much of the research currently provides evidence of efficacy rather than effectiveness. Nevertheless, interventions to promote walking could contribute substantially towards increasing the activity levels of the most sedentary.
