The Earliest Feathers from the Lower Cretaceous Dabeigou Formation of North Hebei: Implications for the Early Evolution of the Jehol Biota

open access: yesIntegrative Zoology, EarlyView.
This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...

A roadmap to key traits of invasive Drosophilidae

open access: yesBiological Reviews, Volume 101, Issue 4, Page 1805-1829, August 2026.
ABSTRACT Biological invasions have intensified in recent decades, mostly driven by international trade and travel, raising significant concerns, particularly regarding insect pests. Once non‐native species establish, they can disrupt natural ecosystem stability, undermine agroecosystem sustainability and cause substantial economic losses.

Optimisation of a Novel Class of DNA Gyrase Inhibitors to Improve Antibacterial Activity

open access: yesChemMedChem, Volume 21, Issue 11, 15 June 2026.
This article describes efforts to increase the antibacterial activity of a recently reported class of novel DNA gyrase inhibitors known as the isoquinoline sulphonamides by improving their uptake in bacterial cells. As antibiotic resistance continues to rise, the need for new antibacterials is clear.

Extending the Geographic Range of Pterosaurs in the Araripe Basin: First Record from the Romualdo Formation (Araripe Basin) in Piauí, Brazil

open access: yesAnais da Academia Brasileira de Ciências
Abstract The Araripe Basin in northeastern Brazil is a key site for Cretaceous pterosaur fossils from Gondwanan deposits. Most discoveries are concentrated in its northern portion, particularly in Ceará state, within the Crato and Romualdo formations. In contrast, records from the southern part of the basin, especially in Piauí and Pernambuco, remain ...

Unusual occurrence of Cochlichnus in aeolian sandstones: evidence for a stiletto fly larval origin

open access: yesPapers in Palaeontology, Volume 12, Issue 3, May/June 2026.
Abstract Cochlichnus anguineus is an ichnotaxon recognized for its distinctive regular wavy morphology. It is a characteristic trace fossil typically associated with aquatic and marginal aquatic environments. However, in this study we examine its unusual occurrence in the aeolian sandstones of the Botucatu Formation (Lower Cretaceous, Paraná Basin ...

Hyperdominant Trees Reveal Savanna Vulnerability Under Climate Change

open access: yesGlobal Change Biology, Volume 32, Issue 4, April 2026.
The Brazilian Cerrado's forest structure relies disproportionately on just 30 hyperdominant tree species, which represent 50% of all individuals despite accounting for only 2% of species richness. This study evaluates their vulnerability under climate change scenarios for 2100.
