Unshared on the top: strong segregation of pathogen communities between western honey bees and wild bees in a retreating glacier foreland

Oikos, EarlyView.
Shared flowers can facilitate pathogen transmission between managed honey bees and wild bees, yet this process remains poorly understood in ecosystems undergoing rapid environmental change. Using a glacier foreland in Switzerland, we present the first study on how glacier retreat stages and bee life‐history traits influence pathogen occurrence across ...

Demonstrating limitations of area‐restricted search as a foraging mechanism

Oikos, EarlyView.
Foragers often rely on simple behavioral rules that translate local environmental cues into movement decisions. One of the most widespread rules is area‐restricted search (ARS), in which movement becomes less directional following resource encounters. ARS is generally considered effective for exploiting clustered resources, yet recent conceptual work ...

The pistil as a traffic light: Yellow‐to‐red color change likely influences pollinator visitation patterns in Saxifraga fortunei (Saxifragaceae)

PLANTS, PEOPLE, PLANET, EarlyView.
Flowers can communicate reproductive status to pollinators through visual cues. In Saxifraga fortunei, pistils often changed from yellow to red after pollination, and hoverflies and honeybees preferentially visited flowers with yellow pistils. This pattern suggests that a post‐pollination color shift confined to the pistil can reduce revisits to ...

The defence of the honeybee community [PDF]

Proceedings of the Royal Society of London. Series B - Biological Sciences, 1954
Abstract Pairs of colonies of differently coloured bees were placed with their entrances only 2 in. apart, and m any bees tried to enter the wrong colony, as if it were their own. Strangers were recognized by their different scent, and their reception depended upon foraging conditions.

Theoretical Analysis of Androstenone Adsorption on Chimpanzee and Gorilla Olfactory Receptors (G‐Protein): Statistical Physics Modeling, Molecular Docking Simulation, and Thermodynamic Investigation

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT An advanced theory based on statistical physics was applied to microscopically investigate androstenone adsorption and its relationship with olfactory perception in chimpanzees and gorillas. For this purpose, dose–response curves of androstenone on olfactory receptors of chimpanzee OR7D4 and gorilla OR7D4 were analyzed by statistical physics ...

A miR-JL-5 inhibitor modulates the proliferation of Nosema ceranae in Apis cerana

Frontiers in Insect Science
Background and aimsApis cerana is the native host of Nosema ceranae (N. ceranae). Previous studies reported that N. ceranae was more harmful to the new host (Apis mellifera) than the original host that had spread globally and become one of the factors ...

Addition and subtraction by honeybees [PDF]

Learning & Behavior, 2019
Howard, Avargues-Weber, Garcia, Greentree, and Dyer (Science Advances, 5,1-6, 2019) report experiments in which honeybees initially shown a number of shapes could subsequently choose a pattern that added or subtracted one from that number. Further, the operations of addition and subtraction were cued by the colors of the shapes.

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Melittin Reprograms Tumor‐Associated Macrophages Through CD18‐Mediated Immunomodulation

Phytotherapy Research, EarlyView.
Melittin selectively targets CD18 to deplete M2‐TAMs and remodel the TME to suppress tumor growth. ABSTRACT Tumor‐associated macrophages (TAMs), particularly the M2‐like subtype, contribute to an immunosuppressive tumor microenvironment and promote tumor progression.

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full
