(Sub)stellar companions shape the winds of evolved stars
Binary interactions dominate the evolution of massive stars, but their role is less clear for low- and intermediate-mass stars. The evolution of a spherical wind from an asymptotic giant branch (AGB) star into a nonspherical planetary nebula (PN) could be due to binary interactions. We observed a sample of AGB stars with the Atacama Large Millimeter/submillimeter Array (ALMA) and found that their

Structure-based design of prefusion-stabilized SARS-CoV-2 spikes
The coronavirus disease 2019 (COVID-19) pandemic has led to accelerated efforts to develop therapeutics and vaccines. A key target of these efforts is the spike (S) protein, which is metastable and difficult to produce recombinantly. We characterized 100 structure-guided spike designs and identified 26 individual substitutions that increased protein yields and stability. Testing combinations of b

Structural basis for neutralization of SARS-CoV-2 and SARS-CoV by a potent therapeutic antibody
The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in an unprecedented public health crisis.

Seismic ocean thermometry
More than 90% of the energy trapped on Earth by increasingly abundant greenhouse gases is absorbed by the ocean. Monitoring the resulting ocean warming remains a challenging sampling problem.

Predicted growth in plastic waste exceeds efforts to mitigate plastic pollution
Plastic pollution is a planetary threat, affecting nearly every marine and freshwater ecosystem globally. In response, multilevel mitigation strategies are being adopted but with a lack of quantitative assessment of how such strategies reduce plastic emissions. We assessed the impact of three broad management strategies, plastic waste reduction, waste management, and environmental recovery, at di

Diet posttranslationally modifies the mouse gut microbial proteome to modulate renal function
Associations between chronic kidney disease (CKD) and the gut microbiota have been postulated, yet questions remain about the underlying mechanisms. In humans, dietary protein increases gut bacterial production of hydrogen sulfide (H 2 S), indole, and indoxyl sulfate. The latter are uremic toxins, and H 2 S has diverse physiological functions, some of which are mediated by posttranslational modif

The ecological and evolutionary consequences of systemic racism in urban environments
Urban areas are dynamic ecological systems defined by interdependent biological, physical, and social components. The emergent structure and heterogeneity of urban landscapes drives biotic outcomes in these areas, and such spatial patterns are often attributed to the unequal stratification of wealth and power in human societies. Despite these patterns, few studies have effectively considered stru

Species-specific pace of development is associated with differences in protein stability
Although many molecular mechanisms controlling developmental processes are evolutionarily conserved, the speed at which the embryo develops can vary substantially between species. For example, the same genetic program, comprising sequential changes in transcriptional states, governs the differentiation of motor neurons in mouse and human, but the tempo at which it operates differs between species

Looking at neurodevelopment through a big data lens
The formation of the human brain, which contains nearly 100 billion neurons making an average of 1000 connections each, represents an astonishing feat of self-organization. Despite impressive progress, our understanding of how neurons form the nervous system and enable function is very fragmentary, especially for the human brain.

HDAC6 mediates an aggresome-like mechanism for NLRP3 and pyrin inflammasome activation
Inflammasomes are supramolecular complexes that play key roles in immune surveillance. This is accomplished by the activation of inflammatory caspases, which leads to the proteolytic maturation of interleukin 1β (IL-1β) and pyroptosis. Here, we show that nucleotide-binding domain, leucine-rich repeat, and pyrin domain–containing protein 3 (NLRP3)- and pyrin-mediated inflammasome assembly, caspase

Species-specific segmentation clock periods are due to differential biochemical reaction speeds
Although mechanisms of embryonic development are similar between mice and humans, the time scale is generally slower in humans. To investigate these interspecies differences in development, we recapitulate murine and human segmentation clocks that display 2- to 3-hour and 5- to 6-hour oscillation periods, respectively. Our interspecies genome-swapping analyses indicate that the period difference

Evaluating scenarios toward zero plastic pollution
Plastic pollution is a pervasive and growing problem. To estimate the effectiveness of interventions to reduce plastic pollution, we modeled stocks and flows of municipal solid waste and four sources of microplastics through the global plastic system for five scenarios between 2016 and 2040. Implementing all feasible interventions reduced plastic pollution by 40% from 2016 rates and 78% relative

Following the microscopic pathway to adsorption through chemisorption and physisorption wells

In this work, we present experiments that revealed a quantitative energy landscape and the micro

As rates of new coronavirus disease 2019 (COVID-19) cases decline across Europe owing to nonpharmaceutical interventions such as social distancing policies and lockdown measures, countries require guidance on how to ease restrictions while minimizing the risk of resurgent outbreaks. We use mobility and case data to quantify how coordinated exit strategies could delay continental resurgence and li

90S pre-ribosome transformation into the primordial 40S subunit
Production of small ribosomal subunits initially requires the formation of a 90 S precursor followed by an enigmatic process of restructuring into the primordial pre-40 S subunit. We elucidate this process by biochemical and cryo–electron microscopy analysis of intermediates along this pathway in yeast. First, the remodeling RNA helicase Dhr1 engages the 90 S pre-ribosome, followed by Utp24 endon

Cryo-EM structure of 90S small ribosomal subunit precursors in transition states
The 90 S preribosome is a large, early assembly intermediate of small ribosomal subunits that undergoes structural changes to give a pre-40 S ribosome. Here, we gained insight into this transition by determining cryo–electron microscopy structures of Saccharomyces cerevisiae intermediates in the path from the 90 S to the pre-40 S . The full transition is blocked by deletion of RNA helicase Dhr1.

T cells take the lead in controlling SARS-CoV-2 and reducing COVID-19 disease severity
A multi-layered, virus-specific immune response is important for controlling SARS-CoV-2 during the acute phase of the infection and reducing COVID-19 disease severity, with the bulk of the evidence pointing to a much bigger role for T cells than antibodies. A weak or uncoordinated immune response, on the other hand, predicts a poor disease outcome.
