In ant colonies infected by a tapeworm parasite, uninfected workers show signs of stress-related gene activity, in part because they're caring for infected nestmates (Photo by Matt Hamer, via AntWiki)
Parasite prevalence in a social host has colony-wide impacts on transcriptional activity and survival

Photo of workers, alates, and pupae of Temnothorax nylanderi, the ant species featured in the study: A mass of white ant pupae with larger, darker workers tending them, and a few very large winged alates apparently getting in the way
Figure 3 from the paper, showing survival curves for queens, infected workers, healthy nurse-workers, and healthy foragers in colonies with no, low, or high infection prevalence; all categories of ants have reduced survival in more-infected colonies but infected workers have higher survival than queens in infected colonies!

Large Language Model-Empowered Channel Prediction and Predictive Beamforming for LEO Satellite Communications
Accurate channel prediction and effective beamforming are essential for low Earth orbit (LEO) satellite communications to enhance system capacity and enable high-speed connectivity. Most existing channel prediction and predictive beamforming methods are limited by model generalization capabilities and struggle to adapt to time-varying wireless propagation environments. Inspired by the remarkable generalization and reasoning capabilities of large language models (LLMs), this work proposes an LLM…
