Scientists have found out exactly how an exercise-triggered molecule suppresses hunger signals in the brain, leading to weight loss. It could be harnessed as a therapeutic, providing the same benefit without the work it takes to produce it naturally.

In a landmark study, scientists have found that a specific rhythm in our brains determines how well we process the world around us. This discovery could change how we understand and treat focus, attention and memory in Alzheimer's disease and ADHD.

A loss of smell can be one of the earliest warning signs of Alzheimer’s disease, but the cause of this sensory change have been unclear. Now, a study reveals that the problem may not lie in the nose or olfactory bulb itself, as previously thought.

In a breakthrough, scientists have transferred a courtship behavior from one species to another, triggering the recipient to perform this completely foreign act as if it was natural. It's a feat that has never been genetically engineered before.

Metallic nanoflowers may be the next frontier in brain health, reducing oxidative stress, protecting mitochondria, and even extending lifespan in lab models. A new study shows they hold “incredible potential” as neuroprotective agents.

We've long known how the nerve endings in our skin detect cold and swiftly relay the information to our brains, but we haven't understood exactly how it works. Scientists have now solved the puzzle, unlocking the mystery of this temperature pathway.

Gut support cells communicate with surprising precision – like brain neurons – to send instructions to the stem cells responsible for maintaining and healing the intestine. The discovery may change our understanding of tissue repair and gut diseases.

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.
