Discontinuing five decades of vitamin A supplementation policy in India without valid scientific evidence: A step in Haste
I read the correspondence by Sachdev et al. [1]. The contents were rather harsh, and they continued to present incorrect arguments to justify their decision to discontinue the universal VAS programme in India. The authors have deliberately avoided direct evidence-based responses to the queries raised in my previous correspondence [2]. Before responding to each of…

Learning few-shot imitation as cultural transmission
Abstract Cultural transmission is the domain-general social skill that allows agents to acquire and use information from each other in real-time with high fidelity and recall. It can be thought of as the process that perpetuates fit variants in cultural evolution. In humans, cultural evolution has led to the accumulation and refinement of skills, tools…

Comparison of 18F-based PSMA radiotracers with [68Ga]Ga-PSMA-11 in PET/CT imaging of prostate cancer—a systematic review and meta-analysis
![Comparison of 18F-based PSMA radiotracers with [68Ga]Ga-PSMA-11 in PET/CT imaging of prostate cancer—a systematic review and meta-analysis](https://static.beescdn.com/news.myworldfix.com/2023/11/41391_2023_755_Fig1_HTML.png)
Abstract Background Prostate-specific membrane antigen (PSMA) positron emission tomography (PET)/computed tomography (CT) has become an increasingly established imaging modality in the staging of prostate cancer (PCa). Numerous PSMA-based tracers are currently available, however, there is a lack of consensus on the optimal radiotracer(s) for PSMA PET/CT. This study aims to investigate whether Fluorine-18 (18F)-labelled PSMA…

Educational innovation: the architecture of digital technologies as a catalyst for change in university teacher training
Abstract The aim of this research was to determine the impact of the architecture of digital technologies in university teacher training as a catalyst for change and educational innovation. Methodologically, it is framed in a quantitative approach with a pre-experimental design and an explanatory level, with a sample of 269 teachers out of a total…

Students, faculty members participate at UN climate talks
Vanessa Forbes-Pateman does not need a meteorologist or computer model to tell her that anthropogenic climate change already is having a catastrophic impact on the planet. The University of Miami doctoral student has experienced it firsthand in the form of more powerful tropical cyclones that have battered her homeland. Flood waters spawned by Hurricane Matthew…

Extraterrestrial life: back story for the control experiment
CORRESPONDENCE 28 November 2023 Manuel Lerdau University of Virginia, Charlottesville, Virginia, USA. Your discussion of one of my favourite Nature papers, from 30 years ago (C. Sagan et al. Nature 365, 715–721; 1993), omitted mention of the theoretical underpinnings of the authors’ ‘control’ experiment to detect life on Earth (see Nature 622, 451–452; 2023). Access…

A multivariate decomposition analysis of modern contraceptive utilization among married women in the emerging region of Ethiopia (2000–2019)
Abstract Ensuring universal access to family planning services is a proven strategy to improve reproductive health as well as economic development. Assessing the trend and identifying the factors for the change in modern contraceptive utilization is crucial to design effective measures, but trend analysis was not conducted previously. Thus, this study aimed to assess the…

A novel RF-CEEMD-LSTM model for predicting water pollution
Abstract Accurate water pollution prediction is an important basis for water environment prevention and control. The uncertainty of input variables and the nonstationary and nonlinear characteristics of water pollution series hinder the accuracy and reliability of water pollution prediction. This study proposed a novel water pollution prediction model (RF-CEEMD-LSTM) to improve the performance of water…

Effective gestational weight gain advice to optimize infant birth weight in Japan based on quantile regression analysis
Abstract The optimal range of gestational weight gain (GWG) was recently raised in Japan. This may help reduce small-for-gestational-age (SGA) infants, but may also increase large-for-gestational-age (LGA) infants. This study performed hypothetical experiments to determine effective GWG advice based on quantile regression analysis. In a total of 354,401 singleton pregnancies registered in the perinatal database…

Method for obtaining reliable R-waves in fish electrocardiograms by utilizing conductivity of seawater
Abstract A simple method for measuring bioelectric signals of fish in seawater is expected for managing the health of farmed fish and clarifying the ecophysiology of natural fish. We previously proposed a simple and unique method for measuring bioelectric signals of fish by inserting only one special internal electrode (which can be isolated from seawater)…
