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.

[Alexander L Davis @AlexLDavis_]

Come work with the best advisor anyone could ever hope for!

[Sonke Johnsen @sonkelab]

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

@JasonPDinh Congrats!

🤯THIS JUST IN🤯

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

[Sonke Johnsen @sonkelab]

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.

@JasonPDinh ^ Seconded if any current PhDs are considering consulting

[Jason Dinh is just trying his best @byjasonpdinh]

my first story with @DiscoverMag is live!

new research from @NOCnews shows that deep-sea oil and gas pipelines are biodiverse trash collectors. https://t.co/LlfIOvtGIu

@WildlifeMcCoy @CoralReefFish I’d be curious to know if these guys use the same trick! I think there is one reported example of a similar structure to the deep-sea fish skin in a reef fish, but I would have to dig it up.

[Dakota McCoy, Ph.D. @WildlifeMcCoy]

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). https://t.co/z3jhJycS5B

[Sonke Johnsen @sonkelab]

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

[Ethan Mollick @emollick]

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. https://t.co/2K5E4wZ3Hb
