Neuronal fatty acid oxidation fuels memory after intensive learning in Drosophila - Nature Metabolism Neurons are shown to use fatty acid β-oxidation as a fuel source for memory formation upon intensive learning in Drosophila, challenging the view that neurons are unable to use fatty acids for energy ...

Textbooks said neurons don’t burn fatty acids for energy🤔. Our study delivers the first in vivo demonstration that fatty acid oxidation in defined memory neurons fuels memory formation.

Closing chapter of my PhD 🥳, out today in Nature Metabolism💥 @natmetabolism.nature.com

Postdoc Portrait: Priya Prakash This postdoc uncovers how glial dysfunction drives neurodegeneration in a rare movement disorder.

I was featured on The Scientist as a part of their 'Postdoc Portraits' series where I spoke about my scientific career path and ongoing work on oligodendrocyte dysfunction in neurodegeneration. Check it out! www.the-scientist.com/postdoc-port...

Heartbreaking, well crafted thread from an immigrant scientist who’s decided being in the US isn’t worth the struggle anymore.

After 13 years in the US, I’ve made the difficult decision to leave. Having packed up everything and rethought about priorities, rather painstakingly, while I’m sad to leave the life I’ve made here, I’m also relieved that I won’t have to plan my life around immigration policies anymore.

Oligodendroglial fatty acid metabolism as a central nervous system energy reserve - Nature Neuroscience Brain functions require a constant supply of glucose.

We've been doing some amazing stuff outside the astrocyte realm.
Check out our latest Oligo investigation led by @pryprk.bsky.social !

🌏 We thank all the amazing clinicians, geneticists, and neuroscientists across continents who contributed to these two studies to better understand and treat this rare disorder.

This work was primarily funded by the Collaborative Center for XDP (CCXDP) and NHGRI’s Center of Excellence in Genomic Science – The Center for Synthetic Regulatory Genomics at NYU Langone Health.

This work represents a close collaboration between the @liddelowsa.bsky.social 🫶 @jefboeke.bsky.social labs at NYU Grossman School of Medicine as a part of The Dark Matter Project @darkmatterproject.bsky.social.
