Conserved Molecular Responses to Arsenite Exposure in Drosophila melanogaster

This study identifies conserved molecular responses to arsenite exposure in Drosophila, revealing shared pathways with human arsenic-related diseases.

No molecular evidence for Muller's ratchet in mitochondrial genomes

The paper re-evaluates evidence for Muller's ratchet in mitochondrial genomes using three species pairs, finding strong selection in mtDNA and no ratchet-like mutation accumulation.

Low mutation rate but high male-bias in the germline of a short-lived opossum

This study reports the lowest germline mutation rate in mammals and a typical male mutation bias in the gray short-tailed opossum, suggesting alternative mechanisms to cell division drive sex-specific mutation rates.

Unprecedented female mutation bias in aye-ayes

This study finds a female mutation bias in aye-ayes, contrasting the typical male mutation bias in mammals, and identifies potential genetic causes.

CAGEE: computational analysis of gene expression evolution

CAGEE infers gene expression changes across phylogenies and tissue-specific rates, validated on simulated data and applied to Solanum species.
