Brain-Friendly Ways to Sit

We’ve heard it all before: We are sitting too much, and it isn’t good for our brain health.

But not all sitting is equal.

A systematic review of 85 studies has now found health differences between ‘passive’ sitting, like watching TV, and ‘active’ sitting, like reading, playing cards, or using the computer.

Across numerous studies, passive sitting was consistently associated with negative cognitive outcomes, including increased dementia risk.

But putting up your feet doesn’t have to put the mind to rest.

Active sitting activities showed overwhelmingly positive associations with cognitive health.

If that’s what you’re up to right now, your brain might be sitting pretty…

Mysterious Detail in a Raphael Masterpiece

The paintings of Raphael have drawn the attention of millions of art experts and museum visitors over the years.

But artificial intelligence (AI) can see what the human eye cannot.

According to machine learning analysis, the painting Madonna della Rosa may not be entirely the work of the Italian Renaissance painter after all.

The brush strokes, color palette, and shading of the face of St Joseph, in the top left of the painting, don’t match the skilled hand of Raphael.

Perhaps it was a student of his…

Strange Space Metal Found in Ancient Treasure

(Municipal Archaeological Museum of Villena)

An ancient cache of treasure from the Iberian Peninsula contains two objects made from material beyond our planet.

A dull bracelet and a rusted hollow hemisphere are composed of iron from meteorites.

These are some of the oldest iron objects found in the region.

The official Iron Age in this part of the world didn’t start until centuries after the bracelet and hemisphere were made.

Long ago, an advanced material literally fell from the sky.

Maybe it inspired us.

Science Fact of The Week

We emit a light that vanishes when we die.

It’s not some woo-woo paranormal aura; it’s a feature of all living things. The glow comes from the ultra-weak photon emissions of active cells.

It’s far too weak for human eyes to see, but it’s there all the same time…

… until it’s not.

DOPAMINE HIT

Before You Go…

Boop.

Microscope answer: Gut cells.

Who knew your gut was so beautiful? These flower-like objects are cross-sections of intestinal ‘crypts’ – finger-like projections in your colon and small intestine that help with digestion and cell renewal.

That’s all for today… see you next week!
