Students ran for cover as the rain began.
"Is it possible to quantify 'yay big' as an objective measurement? For example, I can present my thumb and index finger to denote a material's #thickness. Yet unlike archaic measures like a cubit or the foot, understanding how to quantify a measure of 'yay big' without a demonstration of an object's measure argues the #measure is subjective and germane."
"That's your thesis?"
He shrugged, "That, or my breeding program for spherical cows."

Cortical thinning is associated with altered neurotransmission in young adults with a history of heavy drinking since adolescence

The article discusses a recent study conducted in Finland that explored the effects of #heavy #alcohol #consumption during #adolescence on #brain #development.

The study followed a group of young adults over a 10-year period, comparing those with a history of heavy drinking in adolescence to those who consumed little or no alcohol. The researchers found that the heavy-drinking group had #lower #cortical #gray #matter #thickness in several brain regions and #altered #neurotransmission compared to the control group.

Specifically, they observed increased activity in inhibitory neurotransmitters and thinner gray matter in the #frontal and #parietal lobes.

The study highlights the potential negative impact of heavy alcohol use during adolescence on brain structure and function, emphasizing the need for further research to understand the underlying mechanisms

Hey, it's #ThickTrunkTuesday @mikako6
What have you got?

I've overlooked my photos of big trees, ancient, thick trunks and more. Amazing and fewer and fewer every year. Here's one of mine from Jamaica. All I had to compare size was this kid that kept following us ever since we left home

A really thick based tree. There are fins from the trunk to roots, enough to form caves in , and a boy standing on one of the *fins. Wider than a bus

Regime shift in #ArcticOcean sea #ice #thickness. We demonstrate that a simple model describing the stochastic process of dynamic sea ice thickening explains the observed ice thickness changes as a result of the reduced residence time. Our study highlights the long-lasting impact of #ClimateChange on the #Arctic #SeaIce through reduced residence time and its connection to the coupled #ocean –sea ice processes in the adjacent marginal seas and shelves of the Arctic Ocean. https://www.nature.com/articles/s41586-022-05686-x
