Inclusive fitness forces of selection in an age-structured population

This paper derives inclusive fitness forces of selection in social species, showing that selection on survival can persist post-reproduction and reproductive selection may not decline monotonically.

Bumblebees retrieve only the ordinal ranking of foraging options when comparing memories obtained in distinct settings

This study shows bumblebees use only ordinal memory of foraging options, not absolute reward values, when making decisions in novel pairings.

Discrimination of edge orientation by bumblebees

This study shows bumblebees can discriminate 7-degree angled edges better than honeybees, suggesting superior angular resolution and potential for complex visual processing.

RNA-specific condensation promotes auto-regulation of polyQ RNA-binding protein Whi3

The paper shows that Whi3, an RNA-binding protein in Ashbya gossypii, auto-regulates its own transcripts through RNA-specific condensation, affecting nuclear cycling and gene transcription.

Automated video tracking and flight analysis show how bumblebees solve a pattern discrimination task using active vision

This study uses automated video tracking and flight analysis to show how bumblebees use active vision to solve a pattern discrimination task by scanning specific regions of visual stimuli.

Circadian rhythm shows potential for mRNA efficiency and self-organized division of labor in multinucleate cells

The paper models circadian rhythms in multinucleate cells, showing mRNA-protein phase separation enables efficient oscillators and self-organized division of labor between nuclei.

Senescence: Still an Unsolved Problem of Biology

This paper argues that senescence remains an unsolved problem in biology, using demographic data to challenge classical theories of aging.
