Understanding the Hygienic Behavioral Dynamics of Ants Using Multi‐State Models

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 4, Page 361-370, April 2026.
Leaf‐cutting ants adjust grooming to pathogen risk and vulnerable nestmates. Multi‐state Markov models reveal shorter, frequent self‐grooming bouts and reduced allogrooming persistence under stress, optimizing social immunity via stigmergic decision‐making.

Asian Precipitation Changes in the Past Millennium: Projection of Volcanic Forcing Onto Internal Mode

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Asian precipitation changes over multiple time scales have been extensively studied, yet the relative roles of external forcing and internal variability in shaping the large‐scale Asian precipitation pattern over the past millennium remain underexplored. Here, we demonstrate that the tripolar pattern of decadal precipitation variability across

Extracting winter North Atlantic Oscillation information from a central European stalagmite [PDF]

open access: yes, 2013
This study explores the potential for extracting winter North Atlantic Oscillation (NAO) information from central European stalagmites using a high resolution calcite δ18O (δ18Ocal) time-series from a stalagmite (AH1) extracted from Atta cave in ...

Does hybrid density functional theory predict a non-magnetic ground state for delta-Plutonium?

open access: yes, 2009
Hybrid density functionals, which replaces a fraction of density functional theory (DFT) exchange with exact Hartree-Fock (HF) exchange, have been used to study the structural, magnetic, and electronic properties of delta-Plutonium.

Practical Quantum Key Distribution with Polarization-Entangled Photons

open access: yes, 2004
We present an entangled-state quantum cryptography system that operated for the first time in a real world application scenario. The full key generation protocol was performed in real time between two distributed embedded hardware devices, which were ...

Insect‐Derived Bioactives for Glycemic Control and Gut Health: A Review

open access: yesFood Frontiers, Volume 7, Issue 2, March 2026.
Insect‐derived bioactive compounds (e.g., peptides, polysaccharides) effectively regulate blood glucose through dual mechanisms: directly inhibiting carbohydrate‐digesting enzymes and glucose transporters, and indirectly modulating gut microbiota to enhance intestinal barrier integrity.
