Flight of the Future: An Experimental Analysis of Event‐Based Vision for Online Perception Onboard Flapping‐Wing Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
A thorough analysis of event‐based vision for flapping‐wing robots is presented, with emphasis on hardware integration, suitability under challenging flight conditions, and real‐time performance. Theoretical and experimental studies demonstrate how these sensors enable robust and efficient onboard perception for ornithopters, thereby advancing autonomy

Osmoxylon‐like fossils from early Eocene South America: West Gondwana–Malesia connections in Araliaceae

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Araliaceae comprise a moderately diverse, predominantly tropical angiosperm family with a limited fossil record. Gondwanan history of Araliaceae is hypothesized in the literature, but no fossils have previously been reported from the former supercontinent.

Mast years increase wind pollination and reduce seed predation in sugar maple (Acer saccharum)

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise In general, mast seeding (intermittent and synchronous seed production) increases plant fitness through economies of scale in which reproduction is more successful in high‐seed years. These benefits have been most studied in wind‐pollinated trees.

Hyperpolarization Modulation of the T‐Type hCav3.2 Channel by Human Synenkephalin [1–53], a Shrew Neurotoxin Analogue without Paralytic Effects

open access: yesAngewandte Chemie, EarlyView.
Human synenkephalin [1–53] (hSYN), an analogue peptide of shrew saliva neurotoxins, was synthesized and its structural characteristics studied. Synthetic hSYN potently activated the T‐type voltage‐gated Ca channel hCav3.2 but did not paralyze mealworms. These findings offer new insight into neurological disorder treatment and evolutionary mechanisms of

CRABS CLAW‐independent floral nectary development in Penstemon barbatus

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Plants secrete carbohydrate‐rich nectar from specialized floral nectary glands to attract pollinators. Arabidopsis and Petunia (rosid and asterid core eudicots, respectively) share genetic control of nectary development requiring activation of CRABS CLAW by euAGAMOUS and PLENA.

Sequence Control in Sulphur‐Containing Ring‐Opening Co‐ and Terpolymerisations

open access: yesAngewandte Chemie, EarlyView.
Sulphur‐containing polymers offer unique avenues for degradability, recyclability and optical performance—but their synthesis is often plagued by side reactions. This minireview outlines recent strategies to control or harness O/S scrambling in ring‐opening co‐ and terpolymerisations, enabling precise sequence control.
