A Perspective explores the consequences of bypassing natural selection in assisted reproduction—including the filtering of sperm for quality inside the female reproductive tract—and options to mimic such selection to reduce risks to offspring. In PNAS Nexus: academic.oup.com/pnasnexus/ar...

Assisted reproductive technologies (ART) can bypass female-modulated sperm selection (top of figure) that ensure that genetically compatible or competent sperm are used for fertilization. ART can also introduce a range of novel environmental stressors (bottom of figure) that generate epigenetic modifications in offspring. Failure to design procedures that both mimic natural conditions and mitigate the harmful effect of unnatural environmental conditions during ART can impact the health trajectories of ART offspring and potentially their descendants.

ARC says they’ll release the Discovery Projects 2025 outcomes tomorrow. Recently, outcomes announcements have tended to happen at/around 11am Canberra time. My bot will pick up the announcement in RMS’s database and post immediately. Good luck!

A really exciting new study: evidence that males evolve better sight in order to detect female dishonesty in dance flies. One for the textbooks! A male resistance trait! Great one from @rosalindmurray @luc_bussiere @dtgwynne & team academic.oup.com/evolut/advan...

Sexually antagonistic coevolution can explain female display signals and male sensory adaptations

Abstract. The prevalence and diversity of female ornaments pose a challenge to evolutionary theory because males should prefer mates that spend resources o
