Plain-English brain science news on RNA editing, astrocytes, and the blood-brain barrier — curated by Hyosung Kim at Vanderbilt University.https://hyosungsci.pages.dev/en-ushttps://hyosungsci.pages.dev/news/rna-editing-invisible-proofreader/https://hyosungsci.pages.dev/news/rna-editing-invisible-proofreader/Every day, your cells silently rewrite millions of RNA letters. Here is how ADAR enzymes do it, why neurons and glia depend on it — and why scientists want to borrow the trick.Thu, 01 Oct 2026 00:00:00 GMThttps://hyosungsci.pages.dev/news/reactive-astrocytes-firefighters/https://hyosungsci.pages.dev/news/reactive-astrocytes-firefighters/When the brain is injured, its most abundant support cells transform. New research explains how astrocytes amplify inflammation through the TNF–STAT3 axis and the complement protein C3 — and what that means for Alzheimer's disease.Sun, 20 Sep 2026 00:00:00 GMThttps://hyosungsci.pages.dev/news/growing-bbb-in-a-dish/https://hyosungsci.pages.dev/news/growing-bbb-in-a-dish/The brain's border wall keeps drugs out of the brain — a headache for medicine and a marvel of biology. Human stem-cell models now let us grow that wall in the lab. Here's how it works and what it's revealing.Thu, 10 Sep 2026 00:00:00 GMThttps://hyosungsci.pages.dev/news/crispr-screens-brain-inflammation/https://hyosungsci.pages.dev/news/crispr-screens-brain-inflammation/Instead of testing genes one at a time, CRISPR screens can silence thousands of genes at once. Here is how pooled and arrayed screens reveal what keeps astrocytes inflamed — and what calms them down.Wed, 02 Sep 2026 00:00:00 GMT
