This is so awful I don’t know how to express how awful it is.

From 1,750–2,000 m deep, we collected one of the rarest deepsea fishes out there: a one-jaw eel (family Monognathidae). Only ~100 specimens of this group are known worldwide and we hold the largest collection (~46), most just a few inches long… The one we collected though, 6 inches or 154 mm!

“These studies establish hypoxia as the driver of heart asymmetry and reveal a mechanistic connection between the hypoxic cave environment and the evolution of a novel trait.”

Our Fish EvoDevoGeno Lab @michiganstateu.bsky.social has its 10th anniversary today! 🐠🐟🧪🧬🔬

Thanks to all lab members - present & past, pictured or not - for making the last decade a success!

& thanks to our partners in crime of the @brainyfishguts.bsky.social Lab, too!

Graphic helps visualize how MYF funds FEWER grants despite the increase in budget approval by Congress. https://www.researchamerica.org/wp-content/uploads/2025/11/ACT-for-NIH-Multi-Year-Funding-One-Pager_October-2025.pdf

🧪IMPORTANT! This graphic explains how science all over the US is funded. Congress approved a 2% increase in the #NIH budget for FY 26.

Buried in the bill-
Shift of ~40% of grants to MYF. This will still result in a 35% DECREASE in the NUMBER of grants funded per yr.

Russel Vought is behind this.

Ah the good old days

Cartoon zebrafish with green lit-up brain, in well of plate responding to hit molecule.

Drug discovery for nervous system disorders is really challenging. We think early/rapid in vivo testing with zebrafish will accelerate the drug development cycle for conserved targets. Check out our proof-of-principle pilot study and virtual drug discovery pipeline (tinyurl.com/3whr23hs). #Skytorial

‘Remote controlled’ proteins illuminate living cells The discovery that some fluorescent proteins are sensitive to magnets could lead to the development of switchable drugs and biosensors.

Researchers have engineered magnetically controlled fluorescent proteins that can be remotely dimmed and brightened in cells and living animals

Bogue (Boops boops) Boops boops /ˈboʊ.ɒps/; Greek: βόωψ boōps, literally 'cow-eye'), commonly called a bogue, is a species of seabream native to the eastern Atlantic. Its common name in most languages refers to its large...

The African turquoise killifish (Nothobranchius furzeri) is known as one of the fastest ageing vertebrates. It reaches sexual maturity after 14 days post hatching and has an average lifespan of 4-9 months. For more on this model organism, read pmc.ncbi.nlm.nih.gov/articles/PMC... #TeleostTalk 🧪

If you are submitting an NIH grant in February, you will be required to use SciENcv to prepare you biosketch.

IT IS MUCH WORSE THAN YOU CAN POSSIBLY IMAGINE.

Set aside *at least* 4 hours just to transfer an existing an biosketch into SciENcv.

The transcription of a single olfactory receptor per neuron is enforced by epigenetic silencing of their enhancers The ability to discriminate thousands of odors in our environment requires each olfactory neuron to express a single olfactory receptor from hundreds of available genes. The biochemical mechanism enfo...

This went under the radar but answers a fundamental question in Epigenetics...

From many hundreds of olfactory receptor genes, each neuron selects expression of only single one (near-randomly). How?

Next, in my miniseries on early researchers using zebrafish is Jane M. Oppenheimer, fish embryologist and science historian par excellence. (True, I’m cheating here a bit, but if I mentioned Hellen Battle in the previous bluetorial, it is fair to mention Oppenheimer here.) (1/4)

“This approach effectively complements the temporal precision achievable through post hoc activity detection methods & expands the accessibility of large-scale behavioral circuit dissection beyond highly specialized real-time volumetric imaging equipment.”

Over the past weeks I have been reading the earliest papers on zebrafish development, and came to realize that in the “canonized" version of zebrafish history we neglect some important people pre-Streisinger. I will try to correct here the record. Let’s start with Edward C. Roosen-Runge. (1/7)
