TIMS Techniques for Measuring Strontium Isotope Ratios in Apatite Grains and Application to Igneous Rock Petrology

open access: yesRapid Communications in Mass Spectrometry, Volume 41, Issue 1, 15 January 2027.
ABSTRACT Rationale This study evaluates the potential of Sr isotopic compositions in apatite grains from magmatic rocks as a proxy for initial 87Sr/86Sr ratios, addressing the need for alternative approaches to conventional whole‐rock analyses in isotopic studies of granitoid systems.

Predicting the alternative conformation of a known protein structure based on the distogram of AlphaFold2

open access: yesQuantitative Biology, Volume 14, Issue 4, December 2026.
Abstract AlphaFold2 (AF2) has become one of the most established and leading tools for predicting protein structures, although it often favors a single conformation. While it has been shown that sampling different conformations is possible by manipulating the multiple sequence alignment (MSA), the potential for multi‐state information within a standard

Evidence for effectiveness of Extracorporal Shock-Wave Therapy (ESWT) to treat calcific and non-calcific rotator cuff tendinosis – A systematic review

open access: yes, 2011
Extracorporeal shock-wave therapy (ESWT) is suggested as a treatment alternative for calcific and non-calcific rotator cuff tendinosis (RC-tendinosis), which may decrease the need for surgery.

A Newly Discovered Tablet‐Making Facility in Nineveh: Insights From Scientific Analysis

open access: yesArchaeometry, Volume 68, Issue 6, Page 1294-1305, December 2026.
ABSTRACT This paper addresses the question of tablet technology in the Neo‐Assyrian capital city of Nineveh. Recent excavations in the lower town of Nineveh by the Iraqi–Italian Archaeological Expedition uncovered an exceptional assemblage of more than 200 tablets from an elite residence that appears to have included a scriptorium.

Calcific cerebral emboli and aortic stenosis: detection of computed tomography.

open access: yes, 1986
Embolism with brain infarction rarely complicates calcific aortic stenosis (CAS). We report a case with severe CAS where the patient experienced multiple embolic strokes immediately following retrograde heart catheterization.

Microscopy insights into reef coral fluorescent proteins: Diversity, light energy transfer and biological function

open access: yesJournal of Microscopy, Volume 304, Issue 3, Page 301-344, December 2026.
Abstract Fluorescent proteins (FPs) and chromoproteins (CPs) of reef‐building corals, which generate much of their vivid colouration, occupy a distinctive position at the interface of natural photonics, symbiosis biology and fluorescence microscopy.

Lost and Found: Western Honey Bee (Apis mellifera) Matrix Metalloproteinase 1

open access: yesEcology and Evolution, Volume 16, Issue 11, November 2026.
Despite considerable overall improvements in the Western honey bee (Apis mellifera) reference genome over the past two decades, some genes are missing in the current reference assembly (Amel_HAv3.1), potentially interfering with the meaningfulness of downstream analyses.

EMIT Reveals Elevated Calcite Signatures in Shorelines of Lake Powell and Lake Mead Exposed by Drought and Colorado River Management

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Nearly half of Earth’s seasonal freshwater storage variability occurs in human‐managed reservoirs, resulting in large areas of reservoir‐bed that are episodically inundated or subaerially exposed. Here we use hyperspectral data from NASA’s Earth Surface Mineral Dust Source Investigation (EMIT) mission to map calcite mineral assemblages across ...
