#FishADay Demogorgonichthys arcanus Demon Cave Fish. One cave system in northern Alabama. Eyeless; appears to have lost its vision following an evolutionary pathway separate from a close blind relative that is found in the same system! www.scientificamerican.com/article/newl...

Newly discovered ‘demon cave fish’ hid out in Alabama military installation for 40 years

Scientists named this oddball creature after the Demogorgon from Stranger Things

1/11 🐟 2nd new preprint today from @chasedbrownstein.bsky.social We investigated how losing the swim bladder, the organ that most fishes use to control their buoyancy, has shaped the diversity of ray-finned fishes over 90 million years of Earth history. The results surprised us. 🧵

In case you missed it, looks like a very interesting paper: Rare jackpot individuals drive rapid adaptation in Threespine Stickleback www.nature.com/articles/s41...

Rare jackpot individuals drive rapid adaptation in Threespine Stickleback - Nature Communications

Recombination can speed up adaptation by bringing beneficial alleles together. However, this study shows rapid adaptation in Threespine Stickleback fish depends more on the initial frequency of allele...

From the abstract: “promoting a woman to Associate Professor increases female faculty by 1.5 members after 15 years, leads to six additional female PhD graduates over the following decade, and raises the number who subsequently remain in academia and reach tenured positions”

Fascinating paper on the progression of women in academia. 👩🏻‍🔬 ⚛️ 🧪 #AcademicSky docs.iza.org/dp18477.pdf?... Here's an excerpt from the conclusion:

When women do obtain tenure, the effects extend well beyond their own careers. Beyond the direct promotion of the qualifying candidate, departments experience on average one additional female promotion over the subsequent fifteen years, a substantial expansion of the female PhD pipeline, and improved retention and career progression among female doctoral graduates. These effects are concentrated in departments where women are underrepresented, but not entirely absent, suggesting that a minimal female presence is a precondition for trickle-down effects to materialize, whether through mutual support, departmental influence, or other channels that require women not to be entirely isolated.

Look, people. We have superb keynotes, we are giving prizes, we are giving postdocs a megaphone to tell everyone why they should be hired. This is the meeting to be at. Sign up, join us, and have the time of your life while discussing science with people that know where the cleithrum is🐟🧪

In a new study, Prof. Anissa Kempf's team demonstrates in fruit flies that gut function is linked to feeding, sleep, and survival. Their work adds to growing evidence that the gut communicates with the brain and can influence behavior. 🧪@unibas.ch #ScienceAdvances @snsf.ch

Sleeping instead of eating: How the gut influences behavior

Before newly hatched fruit flies feed for the first time, they need to empty their gut. But that’s not all: researchers led by Prof. Anissa Kempf at the Biozentrum have now discovered a surprising lin...

I am happy to announce that my penultimate post-doc paper (Erik Duboue lab/X) is finally out in Science Advances. This work stems from my first cavefish experiments, examining how dark-adapted cavefish larvae respond to changes in illumination. www.science.org/doi/10.1126/...

Evolution of a central dopamine circuit underlies adaptation of a light-evoked sensorimotor response in the blind cavefish

Evolution shifts dopamine neuron responses in cavefish, reversing how light drives their behavior.
