New paper out in @CurrentBiology with @OsbornLab @sonkelab @katiethomas10 and others about ultra-black deep sea fishes! Turns out some deep-sea fish are among the blackest animals on the planet and they use this blackness as camouflage.

Are we only studying half of color signals? Come to my #SICB2024 talk on Thursday at 10:45 am in Arch Building 607, to look at how backgrounds affect the perception of color signals.
Come work with the best advisor anyone could ever hope for!
All are very welcome to create their own PhD project in my Duke Biology lab in in vision/signaling/camouflage/biophotonics/navigation. Stipend ($38,500 USD) is guaranteed for six years via TA/RA/fellowship. Current one-bedroom rent is ~$1600. DM me if interested. #scitwitter

When asleep, glass frogs HIDE THEIR RED BLOOD CELLS INSIDE THEIR LIVERS, which are covered in GUANINE-CRYSTAL DISCO MIRRORS that scatter light & make the frogs 2-3 TIMES MORE SEE-THROUGH.

Amazing work by amazing people! One of the coolest papers I’ve ever read
So rewarding to see years of work led by Carlos Taboada and Jesse Delia in three labs (mine, @yaojj02, Lauren O’Connell) finally come to fruition. Short version: glassfrogs maintain transparency by hiding their red blood cells in their mirrored livers.

New methods paper out, on finite-difference time-domain (FDTD) optical simulations for biologists!! Colorful signals, evolution, bioinspired technology, and more! With Anna Shneidman, @AlexLDavis_ , & Joanna Aizenberg in Micron (@ElsevierPhysics). sciencedirect.com/science/ar…

Congrats to @AlexLDavis_, who led a paper on ultrablack coloration in deep-sea fish coauthored by me, @OsbornLab, @katiethomas10, @freyaGoetz, and Bruce Robison. Just selected as the best paper in 2020 by the deep sea biology society (@DSBSoc)!

As if one needed more reasons to avoid Excel
A third of all genetics papers published in Nature over a decade (and 20% across all journals) had errors due to the fact that many gene have names like SEPT2 (the official name of Septin 2), which were automatically coded as dates by Microsoft Excel. genomebiology.biomedcentral.…

Seeking papers on FDTD simulations in biology! For a review by @AlexLDavis_ and me, we'd welcome (i) links to papers (sea creatures, birds, #colsci, etc) and (ii) images we could reproduce of your species, optical structures (e.g. in SEMs), and simulation screenshots.

For #sicb2021, @AlexLDavis_, @osbornLab, @katiethomas10, @FreyaGoetz, Bruce Robison, and I will be discussing how deep-sea fishes absorb more light than almost anything else on the planet, and why it matters.

#SICB2021 Color segmentation is a major bottleneck in color/pattern analysis, so I built a tool to make it fast, deterministic, and compatible with popular packages (pavo, patternize, etc). And gang: it can handle shiny.

I'm really excited to share this article, now published in @PNASNews.

The fates of mothers and offspring are more tightly linked than you probably think.
We show strong mother-infant fitness links across multiple wild primates.
Detailed explainer⬇️
I'm excited to share a new pre-print, where we explore novel effects of maternal death on offspring fitness across eight populations of seven primate species: biorxiv.org/content/10.1101/….
Done in collaboration with the Primate Life Histories Database (plhdb.org/)

I am BEYOND EXCITED that my first chapter, "A multifunction trade-off has contrasting effects on the evolution of form and function" is in early view @systbiol !
Suction feeders evolve kinematics 13x faster than biters, but their morph evolves slower!

Stoked to share the first publication from my PhD! About assessment and winner effects in snapping shrimp.
Read on if you are interested in animal contests, or if like me, you just think snapping shrimp are some of the raddest animals out there!
