Using Visual Assessments and Tutorials to Teach Solar System Concepts in Introductory Astronomy

Astronomy Education Review, 2010
Visual assessments and tutorials are instruments that rely on student construction and/or examination of pictures and/or diagrams rather than multiple choice and/or short answer questions. Being a very visual subject, astronomy lends itself to assessments and tutorials of this type.

Sedimentary facies and stacking patterns of fluvio‐deltaic and ‐estuarine deposits from the Palaeoarchean Moodies Group in the Stolzburg Syncline (Barberton Greenstone Belt, South Africa)

The Depositional Record, Volume 12, Issue 4, September 2026.
Drillcore BASE‐5B from the Stolzburg Syncline, Barberton Greenstone Belt, reveals a coarsening‐upward, river‐dominated fluvio‐deltaic succession transitioning upward to a fining‐upward, tide‐dominated‐estuarine succession. Abstract Investigating fluvio‐marine depositional environments from early geological times is of great importance, as they provide ...

Synergistic Engineering of Oxygen Vacancies and Topological Surface States in Bi2Te3/TiO2‐X Heterostructures for Highly Efficient Photothermal‐Driven CO2 Photoreduction

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
Integrating the topological insulator Bi2Te3 with oxygen‐deficient TiO2‐X creates a synergistic platform for full‐spectrum CO2 reduction, achieving high‐selectivity C2+ production via enhanced photothermal catalysis and tailored charge dynamics.

The Usage History of the Aqueduct of Nîmes Reconstructed From Carbonate Archives: Operation, Modifications and Late Antique Breakdown and Change

Geoarchaeology, Volume 41, Issue 5, September/October 2026.
ABSTRACT Anthropogenic carbonate deposits in Roman aqueducts can provide detailed environmental and archaeological information. The Roman aqueduct of Nîmes (France), famed for the Pont du Gard bridge, was built around AD 50 to convey water over 50 km to the city of Nemausus for drinking and bathing.

Staying sheltered: geographical variation in nestbox use by a nocturnal raptor outside the breeding season

Wildlife Biology, Volume 2026, Issue 5, September 2026.
Tree cavities and nestboxes are crucial resources for cavity‐nesting birds. While cavities are essential for reproduction, their importance outside the breeding season remains poorly understood, with most existing evidence focusing on nestbox use by small birds to reduce heat loss during winter.

A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions

X-Ray Spectrometry, Volume 55, Issue 5, Page 721-729, September/October 2026.
ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244 Cm sources, and come with severe concerns on radiation safety and isotope availability.

Burn Severity as a Driver of Multi‐Year Increases in Gross Primary Production and Solar‐Induced Fluorescence Following a Wildfire in Arctic Tundra

AGU Advances, Volume 7, Issue 6, September 2026.
Abstract While climate‐driven increases in wildfires are altering the composition and function of Arctic ecosystems, the impact of burn severity on longer‐term changes in community composition and ecosystem fluxes remains less understood, creating uncertainty in estimates of the biome's carbon storage capacity.

A relativistic positioning system exploiting pulsating sources for navigation across the Solar System and beyond [PDF]

, 2011
We introduce an operational approach to the use of pulsating sources, located at spatial infinity, for defining a relativistic positioning and navigation system, based on the use of null four-vectors in a flatMinkowskian spacetime.

An Operational Daily‐Filtered Dominion Radio Astrophysical Observatory F10.7 cm Solar Radio Flux Product

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract The F10.7 solar radio flux density, or F10.7, is a disk‐integrated measure of the Sun's total emission at 10.7 cm (2.8 GHz) and is a widely‐used proxy of solar activity. F10.7 emissions primarily originate from the Sun's upper chromosphere and lower corona. High‐frequency, transient “radio bursts” can dramatically increase the magnitude of F10.
