It's not weird for some species to incorporate toxins from their diet as defenses: poison dart frogs, monarch butterflies, sea slugs, etc

But let's get weird and circuitous with it

#Nicotine was developed by plants to kill insects. As a quirk of #neurochemistry, humans use it addictively, so cigarette butts are everywhere

Birds have figured out they can use them in their nests to repel insect parasites

The original intention of nicotine

Weird!

Trying harder fails against biology. Adapting to new tasks is not a mindset issue. It requires your brain to physically deploy dopamine.

Quick adapters share one biological advantage. Their brains flood with dopamine during sudden changes. This chemical surge enables a smooth pivot.

This brief highlights a methodological advance—integrating dye-free molecular imaging with machine learning—to map chemical alterations across the Alzheimer’s brain. For mental health professionals, the work underscores how neurochemical shifts in memory-related regions may reflect broader brain-wide metabolic disruption, not solely amyloid accumulation, which can inform a nuanced understanding of how neurodegenerative processes relate to cognitive and behavioral symptoms.
