Vincent du Vigneaud was awarded the Nobel Prize in Chemistry 1955 for his research into the ‘love hormone,’ oxytocin. He not only determined its chemical composition, but succeeded in making it by artificial means.

A recent study provides direct evidence for the role of the vagus nerve in gut microbiome-brain communication, addressing a critical gap in the field.
The research demonstrates a clear causal relationship between gut microbiota and vagal nerve activity. 1/

Microglia Act Differently in Male and Female Brains

Microglia, the immune cells of the brain, exhibit sex-specific differences in response to the enzyme inhibitor PLX3397, which is commonly used in microglial research.

While male microglia showed expected depletion after treatment, female microglia displayed increased survival through alternative signaling pathways.

These findings challenge long-standing assumptions of uniform microglial behavior and could reshape research into neurodegenerative diseases like Alzheimer’s and Parkinson’s, where diagnosis rates differ by sex.

Researchers emphasize the importance of sex-specific studies to better understand microglial activity under various conditions, including hormonal changes and inflammation.

This discovery highlights the potential need for tailored therapeutic approaches targeting microglia based on sex.

Further investigation is underway to explore the biological mechanisms behind these differences.

Deep Sleep Drives Brain’s Waste Clearance, Aiding Cognitive Health

Deep sleep is vital for brain health, as it clears waste through the glymphatic system, which relies on norepinephrine-driven pulsations in blood vessels.

These waves occur about every 50 seconds during deep sleep, flushing out harmful proteins linked to neurological diseases like Alzheimer's.

Researchers found that sleep aids like zolpidem can disrupt this process by reducing norepinephrine waves by 50%, impairing waste clearance by over 30%.

This suggests not all sleep provides the same restorative benefits.

The study highlights the importance of natural deep sleep in maintaining cognitive health and preventing disorders.

Further research could refine treatments to optimize sleep's role in brain waste removal.

There's a subtle kind of violence we inflict on ourselves that lives in the word 'should.' In all the ways we try to force our wild, unpredictable hearts into neat boxes of expectation.

"I should be further along by now."
"I should want what they want."
"I should be able to figure this out."
"I should be over this by now."

Each 'should' is a tiny act of war against what is. A rejection of our actual experience in favour of some imagined ideal.

We think these 'shoulds' motivate us, push us to be better. But they're really just shame dressed up as aspiration.

What if, instead of trying to 'should' ourselves into different people, we got curious about who we actually are?

What if every 'should' is actually pointing us toward something important – not about who we ought to be, but about what we're actually longing for?

The path forward isn't through more sophisticated forms of self-coercion.

It's through radical acceptance of what is.

Not as a final destination, but as the only possible starting point for genuine change.
