Strength α‐Quartz: New Results From High Pressure In Situ X‐Ray Diffraction Experiments

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract We present a suite of 13 uniaxial deformation experiments on fine grained polycrystalline α‐quartz conducted in a D‐DIA apparatus monitored with in situ synchrotron x‐rays. Experimental temperatures range from 25°C to 1199°C with pressures between 1.4 and 3.2 GPa, and strain rates between 3.4 × 10−6 s−1 and 1.8 × 10−5 s−1.

Emergence, spread, and impact of high‐pathogenicity avian influenza H5 in wild birds and mammals of South America and Antarctica

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract The currently circulating high‐pathogenicity avian influenza (HPAI) virus of the subtype H5 causes variable illness and death in wild and domestic birds and mammals, as well as in humans. This virus evolved from the Goose/Guangdong lineage of the HPAI H5 virus, which emerged in commercial poultry in China in 1996, spilled over into wild birds,

Vulnerability of marine megafauna to global at‐sea anthropogenic threats

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened ...

Protein tandem repeats that produce frameshifts can generate new structural states and functions

open access: yesThe FEBS Journal, Volume 293, Issue 3, Page 842-858, February 2026.
We explored an alternative protein structure landscape by analyzing amino acid sequences from frameshifted tandem repeats—regions prone to frameshifts. These frameshifts, especially in short repeats, lead to more drastic changes than in non‐repetitive regions, often altering structure, function, localization, and potentially contributing to disease ...

From isolation to insights: mitochondrial complex I in the diatom Phaeodactylum tricornutum

open access: yesThe Plant Journal, Volume 125, Issue 3, February 2026.
SUMMARY Diatoms are among the most ecologically successful microalgae, contributing significantly to marine primary production and global carbon cycling. Their distinctive metabolic architecture, shaped by a complex evolutionary history involving secondary endosymbiosis, includes a highly compartmentalized cell organization and unique metabolic ...
