A worm, H. miamia, appears to have a diffuse 'brain' without regional specialization. "Early brains may have arisen through the condensation of diffuse nerve nets into unregionalized brains, with regionalization evolving secondarily." www.biorxiv.org/content/10.1...

Under Trump, the NIH is giving fewer grants to fewer scientists. The grants awarded are smaller and scientists have less time to spend them.
Projects in cancer, diabetes, aging, neurological disorder, and more are going unfunded.

New research from Dr. @omersharon.bsky.social UCBerkeley!
In aging, slow delta waves intrude phasic REM sleep → linked to worse memory consolidation 🧠 & Alzheimer’s pathology.
Suggests REM sleep plays a critical role in memory & brain health.
