Reduced ornamentation became elaborated in benign environments in a bird species

The study examines tail ornamentation in Pacific swallows, finding that those roosting in safer, less stressful environments have longer tail feathers, suggesting reduced ornamentation can become elaborated in benign conditions.

UV-induced feather color change reflects its porphyrin content

This study shows that porphyrin, a minority pigment, explains UV-induced feather color change in barn swallows, challenging the focus on predominant pigments like pheomelanin.

Male mate preference against tail-elongated females in the barn swallow

The paper tests male mate preference in barn swallows using model presentations and finds males avoid tail-elongated female models, challenging the idea that males prefer more ornamented females.

ALC1 links chromatin accessibility to PARP inhibitor response in homologous recombination deficient cells

This study identifies ALC1 as a key determinant of PARPi toxicity in HR-deficient cells by linking PARP-dependent chromatin remodeling to PARPi response.

In vivo CRISPR screening identifies Fli1 as a transcriptional safeguard that restrains effector CD8 T cell differentiation during infection and cancer

The paper identifies Fli1 as a transcriptional regulator that limits effector CD8 T cell differentiation during infection and cancer, showing its deletion enhances TEFF responses and immunity.

Genetic screening for single-cell variability modulators driving therapy resistance

This study identifies genes that modulate cellular plasticity and influence therapy resistance in cancer cells through CRISPR screens, showing that manipulating plasticity before therapy can alter resistance.
