Department Chair, Duke Neurobiology - Duke University, Durham job with Duke University - School of Medicine | 12852576 The Duke University School of Medicine (SOM) seeks a distinguished neuroscientist to serve as the next Chair of the Department of Neurobiology.

My department, Duke Neurobiology, is searching for a new chair. Ad below. Come work with me, @jmgrohneuro.bsky.social @ennatsew.bsky.social @jorggrandl.bsky.social @jnklab.bsky.social @sbilbo.bsky.social @neurocircuits.bsky.social and many other amazing folks! @dukemedschool.bsky.social

Retinal glia regulate development of the circadian photoentrainment circuit Circadian photoentrainment depends on intrinsically photosensitive retinal ganglion cells (ipRGCs), which convey environmental light information to th…

Our latest paper is out! While the circadian photoentrainment circuit has been extensively studied, the mechanisms regulating its development remain poorly understood. Here we show that retinal Müller glia play a key role in this process. Check it out! www.sciencedirect.com/science/arti...

I wrote a quick-start guide for people to replicate this across the country. It was, in our experience, a very effective way to get real action in a short amount of time.

People are willing to talk to scientists! And when you provide everything, they are happy to contact their reps too. Try it!

Congrats!!

I have previously posted about the slow issuance of NIH award in fiscal year 2025 compared to fiscal year 2024.

These data were across all of the institutes and centers at NIH.

The results can be examined for each institute and center.

Check out our new preprint! Microglia in different layers of the developing retina express distinct gene profiles - implications for how microglia influence development not just in the retina but throughout the CNS.

The Senate Committee on Health, Education, Labor, and Pensions, led by Senator Bill Cassidy (R-LA) - a gastroenterologist with an MD from LSU, just released a report entitled NIH IN THE 21st CENTURY: ENSURING TRANSPARENCY AND AMERICAN BIOMEDICAL LEADERSHIP. Since he is the ranking Republican,

Horace Barlow, by all accounts, was thinking about 30 years ahead of his time. Here is a transcript of the opening keynote I gave at a symposium honoring Horace's scientific legacy: markusmeister.com/2024/12/14/h....

3 reviews on planning, execution, & validation of transcriptomic experiments in neuroscience published in @natureportfolio.bsky.social #NatureNeuroscience.
A MUST READ if you're doing transcriptomics.
3 reviews, an amazing editorial, a beautiful cover – this is the issue of the year!

Transcriptomic changes in retinal ganglion cell types associated with the disruption of cholinergic retinal waves In the early stages of retinal development, a form of correlated activity known as retinal waves causes periodic depolarizations of immature retinal ganglion cells (RGCs). Retinal waves are crucial fo...

New preprint! A wonderful collaboration of our @FellerMarla lab with Matthew Po, and @shekharlab. Here, we dive into the impact of spontaneous activity on the transcriptome of retinal ganglion cells (RGCs), the sole output neurons of the retina. www.biorxiv.org/content/10.1...

Long a ‘Crown Jewel’ of Government, N.I.H. Is Now a Target The agency long benefited from broad bipartisan support. But Republican criticism has intensified, and new choices for top health posts hope to upend the organization.

“While even the agency’s defenders acknowledge that the NIH needs modernization, the radical reforms proposed would be difficult, if not impossible, without YEARS of legal wrangling and significant support from Congress”

Exactly! So let’s work on allies in congress

Parable time: After the incredible successes of quantum electrodynamics in the late 1940s, particle physics went through what is now considered a pretty fallow period in the the 1950s and 60s. Many interesting ideas from that time that survived (selectively summarized much later in Coleman) 1/n

While our bodies seem static, our cells are constantly changing shape or on the move during tissue homeostasis or wound repair & even more dramatically during embryonic development, during events like gastrulation. Defining how cellular machines mediate these events is a key task for our field 1/n

An image showing a labelled red and green colored retina on the left hand side with a white circled bipolar cell. On the right hand side, the circled bipolar cell is shown to scale in comparison with a pyramidal neuron from the brain. It is about 1/10th the size, and barely visible.

This is one of my all-time favorite figures. It shows the size comparison between a retinal bipolar cell and a cortical pyramidal cell in a mouse. Scale bars are great and all but sometimes the sizes just don't compute.

Confocal microscope image of mouse retina labeled with antibodies for PKCalpha (red), TRPM1 (yellow), and 4.1B (cyan).

The retina provides pretty pictures even when antibodies misbehave. I'm calling this one "bipolars in a starry sky".

A sign-inverted receptive field of inhibitory interneurons provides a pathway for ON-OFF interaction... In the retina, visual information is segregated into ON (light increment) and OFF (light decrement) streams. Here, the authors identify a sign-inverting amacrine cell with an inhibitory ON center – ...
