Our paper on how better amino acid substitution matrices trained on cleaned alignments improve gene tree inference, and on best practice for cleaning MSAs more broadly, is now out academic.oup.com/mbe/advance-.... New options in both IQTree and Muscle5. @phylowheeler.bsky.social

Improved gene tree inference from removing alignment errors both from focal genes and when training substitution models

Abstract. Multiple Sequence Alignment (MSA) is a key step in phylogenetic analysis and is prone to error. Unfortunately, algorithms that remove likely alig

Sequence alignments are notoriously prone to error. Our latest preprint offers a new tool for filtering errors out, assesses it and other filtering tools, and recommends new best practice. www.biorxiv.org/content/10.6... @phylowheeler.bsky.social 1/10

Blue lobsters are very rare: 1 in 2 million by some estimates. But SPLIT COLOR LOBSTERS are 1 in *50* million. This lobster is a chimera of two fertilized eggs that fused together, with two distinct genomes: male on one side, female on the other. (📷: Woods Hole Science Aquarium/NOAA Fisheries)

Our review on the evolutionary arms race between copepods and diatoms is now published in @aslo.org #ASLO_LO 🌊 We discuss the most common defense mechanisms found in diatoms, and how copepods have evolved to overcome them. Check it out #openaccess aslopubs.onlinelibrary.wiley.com/doi/10.1002/...

Diatoms–copepods: An evolutionary arms race

Diatoms and copepods are dominating and diverse groups of phytoplankton and zooplankton, respectively. Diatoms account for 25–40% of ocean primary production, and their main predators, copepods, are ...

Somehow this paper has been largely ignored, but the basic idea has been presented by others as novel, or the idea gets misattributed to someone else. If you're interested in #diatom sex and its evolutionary importance, read and cite this paper. www.jstor.org/stable/2460887

In our new pre-print, we established massive single-cell RNA-sequencing for diatoms to investigate key cell fate transitions. Notably, we discovered that the diploid-to-haploid transition is regulated by Myb TFs, a process that is actively ongoing across the Global Ocean! 🌊

No I cannot be on your important panel, sorry. No I cannot review your exciting grant, sorry. No I cannot review your groundbreaking paper, sorry. No I cannot help you with your awesome outreach project, sorry. Because all of this^ is invisible on my uni workload model and therefore worthless. 🤷‍♀️

This is a real timelapse video of the Moon transiting in front of the Earth. It was captured by the Artemis 1 Orion spacecraft in November 2022 while flying at it's furthest point from the Earth. The video covers about 3.75 hours of real time. 🔭🧪
