Deep-sea fish larvae rewrite the rules of how eyes can be built

Deep-sea fish larvae combine features of both rods and cones into a single, highly specialised cell that is optimised for life in between light and darkness.

@biologyopen.bsky.social highlighting our new #OA paper on the impacts of uvr☀️on clownfish embryo development 🐠🥚 @craigefranklin.bsky.social @drfishvis.bsky.social doi.org/10.1242/bio....

Ultraviolet B radiation impairs coral reef fish development

Summary: Ultraviolet radiation (UVR) has significant impacts on yolk sac volume, which may have contributed to the 100% mortality rate of clownfish embryos. However, DNA damage was not as impacted by ...

@adamdownunder.bsky.social, @craigefranklin.bsky.social & co expose clownfish embryos to UV radiation (UVR) corresponding to water depths reflective of their settlement; mimicking what could happen in a future coral reef with fewer structures shielding against UVR. doi.org/10.1242/bio....

The effect of UVR (UVB: 280-315 nm) across developmental age (dpf) of clownfish (A. ocellaris) embryos. Embryos were exposed to either control (no UVR; pink colour bar) or UVR levels representing the within-depth range of A. ocellaris: 6 m (low UVR treatment; 80 µW m2; green colour bar) or 2 m (high UVR treatment; 280 µW m2; blue colour bar) (Braun et al., 2016). UVR exposure occurred for 2 h daily from when eggs were laid (0 dpf) until hatched at 8-9 dpf. On 2 and 5 dpf, individual embryos were collected for (A) mass (mg; n=15 per age per treatment group), and (B) yolk sac volume (mm3; n=15 per age per treatment group). (C) DNA damage (concentration of CPD) only was measurable in embryos exposed to high UVR treatment only (n=13 measured in 2 dpf embryos, and n=8 measured in 5 dpf embryos). The experiment was replicated three times per treatment using two different parent pairs. In all three panels, predicted Bayesian posterior distributions are shown with symbols and error bars representing the median and 0.95 and 0.8 quartile-based credible intervals, respectively.

We developed CrossFilt, a read-level, cross-species filtering approach that avoids these errors without sacrificing usable data. It outperforms all existing strategies and exposes just how much signal in comparative genomics has been misread. doi.org/10.1101/2025...

CrossFilt: A Cross-species Filtering Tool that Eliminates Alignment Bias in Comparative Genomics Studies

Comparative functional genomic studies are often affected by biased read mapping across species due to inter-species differences in genome structure, sequence composition, and annotation quality. We d...
