Two new species of Scaptotrigona Moure, 1942 from the Amazon forest (Hymenoptera: Apidae: Meliponini)

open access: yesEntomoBrasilis, 2022
The aim of this study was to describe Scaptotrigona nigrohirta sp. nov. and Scaptotrigona hylaeana sp. nov., in order to make their names valid, since at least one of these species has already been widely studied and cited, however, never been formally ...

Royal jelly fermented by honeybee queen (Apis mellifera)-derived Lactobacillus panisapium M1 enhances macrophage phagocytosis through the TLR2/MAPK/SR signaling pathway

open access: yesBMC Complementary Medicine and Therapies
Background Royal jelly (RJ) has traditionally been used to maintain health, and its fatty acids (10-hydroxy decanoic acid and 10-hydroxy-2-decenoic acid) are reported to have immunomodulatory effects.

Advancing Research on Biomaterials and Biological Materials with Scanning Electron Microscopy under Environmental and Low Vacuum Conditions

open access: yesAdvanced Engineering Materials, EarlyView.
Herein, environmental scanning electron microscopy (ESEM) is discussed as a powerful extension of conventional SEM for life sciences. By combining high‐resolution imaging with variable pressure and humidity, ESEM allows the analysis of untreated biological materials, supports in situ monitoring of hydration‐driven changes, and advances the functional ...

Color Routing and Beam Steering of Single‐Molecule Emission with a Spherical Silicon Nanoantenna

open access: yesAdvanced Functional Materials, EarlyView.
We experimentally demonstrate broadband directional emission from single molecules using a single spherical silicon nanoparticle assembled via DNA origami. By varying nanoparticle (NP) size and emitter position, we achieve unidirectional emission, beam steering, and color routing at the nanoscale, revealing modal interference as the underlying ...

Cross‐Scale Hierarchical Targeted Delivery System Based on Small‐Scale Magnetic Robots

open access: yesAdvanced Robotics Research, EarlyView.
This article reviews a cross‐scale hierarchical targeted delivery system that integrates magnetic continuum robots and magnetic microrobots. By combining rapid long‐range navigation with precise microscale targeting, the system overcomes key limitations of single‐scale approaches.

Antimicrobials from Venomous Animals: An Overview

open access: yesMolecules, 2020
The inappropriate or excessive use of antimicrobial agents caused an emerging public health problem due to the resulting resistance developed by microbes. Therefore, there is an urgent need to develop effective antimicrobial strategies relying on natural

Mouthparts of the bumblebee (Bombus terrestris) exhibit poor acuity for the detection of pesticides in nectar

open access: yeseLife, 2023
Bees are important pollinators of agricultural crops, but their populations are at risk when pesticides are used. One of the largest risks bees face is poisoning of floral nectar and pollen by insecticides. Studies of bee detection of neonicotinoids have

Honey Bee and Bumble Bee Antiviral Defense [PDF]

open access: yesViruses, 2018
Bees are important plant pollinators in both natural and agricultural ecosystems. Managed and wild bees have experienced high average annual colony losses, population declines, and local extinctions in many geographic regions. Multiple factors, including virus infections, impact bee health and longevity.
