Scientists captured the exact moment cardiac cells self-organize into a coordinated rhythm—seconds before the first heartbeat. Early beats are irregular and shift in origin, yet spread coherently across the heart. Credit to Bill Jia!

Over 90% of anxiety-driven worries never come true.

🧠 The brain and immune system aren’t separate—they form one integrated network. Shared signals let neurons shape immune development and responses, while immune activity feeds back to affect mood and behavior. Brain–body health depends on this dialogue.

🧠 Neuroplasticity 🔄 (Shocking Visualization) The brain isn’t fixed — it constantly rewires. From whole-network shifts to circuit tuning to new synapses forming, plasticity happens at every scale. It’s the engine behind learning, recovery, and adaptation.

🌸 Texas A&M scientists found a way to boost energy in aging cells. Tiny nanoflowers added to stem cells double mitochondrial output, letting them deliver extra power to damaged tissue. Early but promising—animal trials next. 🎥 Video: Texas A&M

The brain’s inhibitory neurons keep billions of signals in check — balancing excitation, refining rhythms, and preventing chaos. This video shows just a glimpse of their incredible diversity. 🎥 Beauty in structure, elegance in control. #Neuroscience

What looks like art is actually biology — a rat liver cell seen under the microscope. Those glowing strands are actin and microtubules, the scaffolding that lets the liver filter blood, detoxify chemicals, and even regrow itself. Credit to Dr. Francisco Lázaro-Diéguez! #Science #Microscopy

Psychedelics may change not just neurons, but neurovascular coupling—the link between brain activity and blood flow. That means some fMRI “network effects” could be vascular. Multimodal imaging is key. #neuroscience #fMRI #psychedelics #serotonin
