Don't Forget the Past! Understanding and Communicating Earth's History is Important for a Sustainable Future

Global Challenges, Volume 10, Issue 7, July 2026.
ABSTRACT The concept of sustainability has been shaped by the history of environmental problems and ecological crises, and the scientific value of studying the past has long been recognized. However, the relevance of studying Earth's past in the context of the sustainability debate goes beyond testing Earth‐system models used for future climate ...

A Nonlinear Quantitative Model for Measuring Concentration Ratios From Raman Intensities

Journal of Raman Spectroscopy, Volume 57, Issue 7, Page 1254-1266, July 2026.
Estimating concentration from Raman intensity ratios is complicated by cross‐contributions from overlapping peaks, causing measured ratios to deviate from the linear behavior assumed in conventional quantitative models. This nonlinear method fully accounts for cross‐contributions, allowing estimation of concentration over several orders of magnitude ...

Abundant interactions and feedbacks between aquatic deoxygenation and the other planetary boundaries suggest “unsafe” levels of oxygen loss with far‐reaching impacts

Limnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Oxygen is critical for nearly all life on Earth, including aquatic species that breathe dissolved oxygen in both freshwater and marine systems. The rapid, global, and anthropogenic loss of dissolved oxygen known as “aquatic deoxygenation” threatens life in these environments, the human communities that depend on them, and Earth system ...

Monthly Energy, Exergy, Environmental, and Economic Performance and Green Hydrogen Production Analysis of a Flat‐Plate Solar Collector‐Driven Organic Rankine Cycle System Under Variable Mass Flow and Irradiance

ChemistryOpen, Volume 15, Issue 7, July 2026.
The feasibility of using a hybrid flat‐plate solar collector–organic Rankine cycle–proton exchange membrane system for the generation of electricity, heat, and hydrogen simultaneously is analyzed. The energy efficiency of the solar thermal system reaches 23.82%, and hydrogen production of up to 13.62 kg/month is achieved while reducing CO2 emissions ...

Correlative X‐Ray and Neutron Tomography of Microbial Biosignatures: Perspectives for Mars Sample Return

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Mars Sample Return (MSR) is the next major frontier in Mars exploration, through which advanced laboratory instrumentation will be used to study Martian samples and answer key questions surrounding Mars' planetary evolution and astrobiology. Non‐destructive, high‐resolution imaging will be critical for preliminary MSR analyses.
