T Cells Found Living in Healthy Brains

https://neurosciencenews.com/t-cells-brain-microbiome-29182/

Contrary to long-standing beliefs, T cells—key immune cells—have been discovered in the healthy brains of both mice and humans. These cells, previously thought to only enter the brain during disease, were most concentrated in a region that regulates hunger and thirst. …

One Molecule to Sleep and Wake: A New Brain Switch Discovered

https://neurosciencenews.com/sleep-molecule-neuroscience-29180/

Researchers studying the tiny roundworm C. elegans have uncovered a surprising mechanism by which a single brain signal controls both falling asleep and waking up. The chemical messenger FLP-11 activates a receptor called DMSR-1 in different neurons to either silence wakefulness or shut down sleep, acting as a biological on-off switch. …

Kindness Sparks Cooperation by Boosting Social Connectedness

https://neurosciencenews.com/kindness-cooperation-social-neuroscience-29181/

New research reveals that everyday niceness—like warm tones, smiles, and active listening—can significantly improve teamwork and increase willingness to cooperate. These small acts foster a sense of social connectedness, which serves as the bridge between kindness and collaboration. …

people often say “humans are above animals, so we can kill them,” but that’s not backed by biology. when a mammal experiences pain, it’s primarily the limbic system and endocrine responses activating, basically the same core structures that process pain and stress in humans.
it’s not about having a bigger cortex or thinking critically, pain is a fundamental biological signal meant to protect the body. this means suffering in a pig is not just an analogy, it’s a real, comparable experience.
so if we accept that pain equals suffering, then the moral distinction based on “higher intelligence” doesn’t hold up. suffering is suffering, regardless of species.
it’s time to rethink ethical hierarchies that ignore the neuroscience of pain.

I continue to struggle through Gödel, Escher, Bach: an Eternal Golden Braid by Douglas Hofstadter. It is full of brilliant insights that seem logical to me. Hofstadter is a brilliant author and much smarter than me. But, I do usually disagree with something in each book that I read, and I did read something I think is incorrect. Hofstadter writes, “Bees and other insects do not seem to have the power to generalize—that is, to develop new class symbols from instances which we would perceive as nearly identical.” This is from a section where he writes about the human brain being able to create mental symbols to represent “classes” of things (e.g., cars) and more specific “instances” of things (e.g., Ford cars).

It has been known since at least the early 1900s (Charles Henry Turner 1867-1923) that insects can sometimes change their food sources to survive under environmental pressures. This suggests an ability to recognize new classes (e.g., foods) and even new instances (e.g., flowers). When an invasive insect is introduced to the U.S. by crossing the Atlantic on a ship, it has to adapt to food sources it has never before encountered and many pest insects have unfortunately been able to do so successfully. I doubt those insects just randomly chewed on rocks and other inedible objects until they stumbled across something edible. Someone correct me if I am wrong.
