Experimental Study on Flow‐Induced Bending and Resistance Reconfiguration of Submerged Flexible Vegetation

open access: yesWater Resources Research, Volume 62, Issue 6, June 2026.
Abstract Accurately determining flexible vegetation resistance remains challenging due to vegetation bending and resistance reconfiguration under water flow. This study conducted laboratory experiments to explore the bending and resistance reconfiguration for single submerged flexible vegetation under water flow, and corresponding factors influencing ...

Microalgal Cell Wall Dynamics at Different Growth Stages Under Cold Stress Conditions: A Study of Ultrastructure and Chemical Composition

open access: yesPhysiologia Plantarum, Volume 178, Issue 3, May/June 2026.
ABSTRACT Microalgae have been gaining attention for biotechnological purposes in different fields, such as food, energy, cosmetics, and bioremediation. However, due to habitat variation across the planet, there is still a scarcity of information on microalgae development in extreme environments, such as those with low temperatures.

Quantifying the Impact of Temporal and Spatial Heterogeneity in Turbulence on Bed‐Load Transport Over Vegetated Beds Under Wave‐Current Conditions

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Laboratory experiments measured velocity and bedload transport in vegetated channels under current‐dominated, combined wave‐current conditions. Waves and vegetation, respectively, introduced temporal and spatial heterogeneity in the velocity, which significantly impacted sediment transport rate.

Successful Endoscopic Ultrasound‐Guided Transgastric Drainage for Intra‐Abdominal Abscess Caused by Delayed Perforation After Gastric Endoscopic Mucosal Resection

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Delayed perforation after gastric endoscopic mucosal resection (EMR) is a rare but serious complication that can lead to intra‐abdominal abscess (IAA) formation. Efficacy of endoscopic ultrasound (EUS)‐guided drainage for IAA remains to be elucidated. A man in his 50s was admitted for EMR of hyperplastic polyps located in the gastric body. The

Tiny predators avoid herbivorous caterpillar traces to prevent accidental predation

open access: yesEcosphere, Volume 17, Issue 4, April 2026.
Abstract We report the first example of predators having a strategy to avoid accidental predation by herbivorous insects. The predatory mites Neoseiulus womersleyi and Euseius sojaensis are smaller than 0.5 mm and lay eggs on plant leaf surfaces; thus, their immobile eggs would be incidentally consumed along with leaves by voracious lepidopteran ...
