Once dismissed as “junk,” a group of RNA molecules has been found to help regrow damaged nerves in mice in new research. The discovery could unlock new ways to treat nerve injuries and even restore growth in the brain and spinal cord.

Dopamine doesn’t flood the brain as once believed – it fires in exact, ultra-fast bursts that target specific neurons. The discovery turns a century-old view of dopamine on its head and could transform how we treat everything from ADHD to Parkinson’s.

In a first-of-its-kind study, researchers zoomed in on PTSD at the single-cell level to better understand how it affects the brain. The findings revealed how trauma can lead to specific molecular changes in some brain cells.

Remarkable new findings about the sugar stores in neurons have unlocked an entire new method of treating cognitive decline, and it furthers our understanding of why GLP-1 weight loss drugs appear to provide a shield against Alzheimer's disease.

What does gut fermentation and neuroinflammation have in common? A lot, according to new research that uncovers how the post-stroke microbiome directly influences brain health and recovery. It opens the door to new ways of restoring cognitive function.

There's newfound hope for stroke patients in recovery, with what researchers believe is the very first drug that can comprehensively deliver rehabilitation without the need for challenging long-term physical therapy.

In a major breakthrough for regenerative medicine, MIT scientists have developed a way to convert skin cells directly into brain cells extremely efficiently, without needing to go through the intermediate step of converting them to stem cells first.

The first-ever "biological computer" powered by human cells, which form an ever-learning neural network, has been launched. It's an entirely new kind of AI – Synthethic Biological Intelligence – and not even its creators can predict its full potential.

Spinal muscular atrophy is a debilitating genetic condition that’s usually fatal by a few years of age. But an intriguing case study might demonstrate a simple new treatment, with a child showing no signs at all two and a half years after birth.

Researchers at Columbia University Irving Medical Center have identified the specific neurons in mice brains that tell them they've eaten enough. This fascinating discovery could play a big role in the future of weight loss treatments for humans.

We've never been closer to accurately assessing whether someone is more susceptible to developing depression due to their biology, with 293 new gene variants found to play a role in ramping up the risk factor. That's 42% more than previously known.

A stage of sleep – reflected in the size of our pupils – is important to committing recent memories to the brain, which could be manipulated to improve cognitive function and even identify issues with being able to recall newer experiences when awake.
