Individuals can gain substantial benefits from collective actions.1,2,3,4,5,6,7 However, collective behaviors introduce new challenges, like coordinating actions, maintaining cohesion, and meeting the needs of different individuals. When making collective movements, leaders are typically thought to gain disproportionate benefits through the choice of more beneficial resources3 and/or earlier acces
Introduction: To increase the sustainability of healthcare, clinical trials must assess the environmental impact of interventions alongside clinical outcomes. This should be guided by Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) and Consolidated Standards of Reporting Trials (CONSORT) extensions, which will be developed by The Implementing Climate and Environmental O
Background: Understanding pesticide exposure variability over time among children is crucial towards understanding potential acute and long-term health effects of pesticides but data is lacking. Objective: We assessed spatiotemporal and seasonal variability of urinary biomarkers in children at five time points across two years within three agriculturally intensive areas of the Western Cape, South
Photoelectron angular distributions are reported for a series of aqueous potassium carboxylate solutions, ranging from bulk-solvated to strongly surface-active species. The quantitative information determined from this work demonstrates how the measured photoelectron angular distributions are influenced by the ions’ increasing propensity for the surface in aqueous solutions. Our study provides ins
BACKGROUND Aspirin reduces the incidence of colorectal adenoma and colorectal cancer among high-risk persons. Observational studies suggest that aspirin may also improve disease-free survival after diagnosis, particularly among patients with tumors harboring somatic PIK3CA mutations. However, data from randomized trials are lacking. METHODS We conducted a double-blind, randomized, placebo-controll

Entanglement has the ability to enhance the transmission of classical information over a quantum channel. However, fully harvesting this advantage typically requires complex entangling measurements, which are challenging to implement and scale with the system's size. In this Letter, we consider a natural quantum information primitive known as a random access code in which the message to be communi
The Large Hadron Collider (LHC) at CERN became operational in 2009 and has since then produced a plethora of physics results from proton–proton (pp) collisions. This short review covers results that relate to soft quantum chromodynamics (QCD) with a focus on nondiffractive physics at midrapidity. Most of the presented results are based on transverse momentum spectra and related derived observables
Introduction The WHO has declared climate change the defining public health challenge of the 21st century. Incorporating climate and environmental outcomes in randomised trials is essential for enhancing healthcare treatments’ sustainability and safeguarding global health. To implement such outcomes, it is necessary to establish a framework for unbiased and transparent planning and reporting. We a
By the end of the eighteenth century, Leiden was a very unhealthy city where life was characterised by disease and untimely death – in particular young children – mainly because of high population density and unhygienic conditions. Morbidity and a high mortality rate gave city life a specific dynamic: many children grew up without one or both parents present, while many elderly men and women had t
Although rising inequality in sub-Saharan Africa has revived debates on the distributional effects of government tax and expenditure policies, there are relatively few long-term empirical studies on this issue. This chapter examines how government fiscal policies—both taxation and public spending—have evolved and shaped inequality trends in colonial and postcolonial Ghana. It finds that fiscal pol
Recent studies have challenged earlier narratives of Africa as historically stagnant and impoverished, instead revealing patterns of booms and busts. While this has advanced understanding of long-term growth, significant gaps remain in our knowledge of historical poverty, especially among self-employed rural populations. This chapter uses published social tables to examine rural poverty in six Afr
Within-sex phenotypic variation can arise through co-option of sexual differentiation mechanisms. Recently, several such cross-sexual-transfer traits have been identified, but we lack a mechanistic understanding of their geographic variation, environmental influences, and phenotypic integration with other traits. Male Polyommatus icarus butterflies are blue, whereas female wing coloration varies f
The incidence of cutaneous melanoma (CM) has risen sharply over the past 30 years, coinciding with the rapidly growing tattoo trend. In Sweden, 20% of the population is tattooed. Repeated reports of the presence of carcinogenic chemicals, such as polyaromatic hydrocarbons, aromatic amines and heavy metals in tattoo ink justifies the investigation of CM risk in relation to tattooing. We aimed to in
Solvers’ participation is essential for successful implementation of crowdsourcing contests for problem solving (CCPS). Many efforts have been made to investigate solvers’ various participation behaviours in CCPS. Whether or not a solver will conduct a behaviour is the result of decision making. However, to our knowledge, few studies concentrated on solvers’ participation from a decision process p
Objectives The aim of this study was to analyse associations between crowded housing and children’s indoor living environment, respiratory and allergic disorders and general health. Design A cross-sectional study. Setting Sweden, using data from the Swedish National Environmental Health Survey 2019. Participants The study sample included 48 512 children (aged 6–10 months, 4 years and 12 years). We
Developing standardized bioengineered constructs that accurately replicate human skin is a largely sought-after goal. Pathways initiated at the nurturing interface with the dermal compartment have the potential to modulate the developing epidermal architecture. Here, we identified ascorbic acid, a dermis-donated metabolite, as key in modulating the phenotypical identity of immortalized keratinocyt
Time- or frequency-dependent (“restricted”) diffusion potentially provides useful information about cellular-scale structures in the brain but is challenging to interpret because of intravoxel tissue heterogeneity. Multidimensional diffusion–relaxation correlation MRI with tensor-valued diffusion encoding enables characterization of intravoxel heterogeneity in terms of nonparametric distributions
single-channel video. 6 min 30 secOften focusing on stories of the supernatural, the transcendent, and the psychedelic, Joachim Koester’s deeply researched work explores the real and imagined limits ofthe human body and mind. Through documentary films, photographic series, and books, he reintroduces repressed histories into the collective memory.Tarantism is a condition resulting from the bite of
The Hunga Tonga eruption on 15 January 2022 (HT-22) induced vigorous volcano–sea interaction. Here we study the stratospheric aerosol and water vapor resulting from the eruption using satellite-based instruments: the CALIOP lidar and the Microwave Limb Sounder (MLS). We investigate the stratospheric relative humidity following the record-breaking water vapor injections from the HT-22 eruption and
