Trends in K‐12 science education research on students' interest, motivation and attitude towards science and technology: A systematic, reproductive and comparative review of 12 more years (2013–2024)

open access: yesReview of Education, Volume 14, Issue 1, April 2026.
Abstract This study presents a systematic, reproductive and comparative review of research on students' interest, motivation and attitude (I/M/A) towards science and technology (S&T) at K‐12 levels, covering the period 2013–2024. As a follow‐up to a previous systematic review (2000–2012), it describes and synthesizes findings from 170 peer‐reviewed ...

Parkes Transient Events. II. Pulsar Single-pulses Database Containing Raw Data Segments

open access: yesThe Astrophysical Journal Supplement Series
We have reprocessed single-pulse candidates from the first four years (1997–2001) of the Parkes Multibeam receiver system observations, creating a new Parkes transient database (PTD II) that contains 165,592 single pulses from 363 known pulsars.

Defining Scales of Field Studies and Experiments to Assess Marine Cloud Brightening

open access: yesAGU Advances, Volume 7, Issue 2, April 2026.
Abstract Solar radiation modification (SRM) is being discussed as a potential option for addressing climate risks while atmospheric greenhouse gas concentrations are reduced to lower levels. However, understanding of the potential efficacy, impacts, benefits and harms of different SRM approaches remains limited.

Long‐Term Reorganization of Ocean Nutrient Distribution

open access: yesAGU Advances, Volume 7, Issue 2, April 2026.
Abstract Nutrient availability is a major driver of ocean biodiversity and productivity, yet long‐term global changes remain poorly constrained. Using over 14 million nitrate and phosphate measurements collected between 1925 and 2025, we quantify long‐term trends in nutrient concentrations across ocean biomes and depths.

How Scientific Is Nursing? Answers From A New Characterization of Science

open access: yesNursing Philosophy, Volume 27, Issue 2, April 2026.
ABSTRACT In the last few decades, nursing scholars have drawn on philosophy to establish the scientific status of nursing. However, well‐known philosophical accounts of science, such as those by Popper and Kuhn, are primarily targeted at the pure natural sciences. Accordingly, the application of such accounts to nursing has led to dubious results.

Resonant Vibrational Excitation and Overtone Vibrational Emissions of Nitric Oxide (NO) in Sub‐Auroral Ion Drift (SAID) Region: A Source of STEVE Continuum Emission

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract At elevated electron temperature (Te≥3000°K ${T}_{e}\mathit{\ge }3000\mathit{{}^{\circ}}\mathrm{K}$) inside Sub‐Auroral Ion Drift, resonant vibrational excitation (RVE) increases the vibrationally excited (v≥8 $v\mathit{\ge }8$) nitric oxide (NO) population in the E‐region, which undergoes overtone vibrational emissions (Δv≥8 ${\Delta }v ...

Surface Air Enrichment of Cosmogenic 35S at a Subtropical Site During the May 2024 Solar Superstorm

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Cosmogenic radiosulfur (35S) is produced in the atmosphere by high‐energy particle interactions and serves as a sensitive tracer of stratospheric intrusions. In May 2024, an extreme solar storm provided a rare opportunity to examine atmospheric 35S responses to intense solar activity.
