Can a simple brain exercise cut dementia by 25%? Much like boosting your speed on the treadmill can unlock physical benefits, a study claims that speed training for your brain has a similar effect. Read more from @:
A group of researchers and technologists are building high-tech sleep masks and “other trippy brain-interference technology” to make lucid dreaming a reality. Read more from @:
🧠💪 Your #brain isn't just a static organ – it's a dynamic system that "remodels" itself based on use. Just like lifting weights builds muscle, pushing your brain into the "discomfort zone" with unfamiliar tasks builds new neural connections that protect your cognitive #health as you age.
What if the idea of the autism spectrum is completely wrong?
From @: "For years, we've thought of autism as lying on a spectrum, but emerging evidence suggests that it comes in several distinct types. The implications for how we support autistic people could be profound."
We’ve all met a narcissist or two. And we all wish they would change, it’s probably safe to say. So can someone be talked out of being a narcissist? @ScienceAlert explores:
Was walking home from work today, when out of the blue, it suddenly felt like my brain just... dropped with a thud in my head. Just my brain, no feeling of vertigo or anything. It was followed by a brief mild headache, for seconds only. It was more alarming than painful and just felt weird and off-putting.
Someone suggested a stress reaction but I've definitely never felt anything like it before. Any ideas?

A tweet by Mark Kretschmann showing two photos of the xAI office on Grokipedia release day. The office is filled with small camping tents set up between desks and along hallways, suggesting that engineers have been sleeping there while working late. The caption notes it’s early morning and the engineers are still in their tents, joking that a good night’s sleep does wonders.
@Daojoan Actually a great graphic illustration of a high efficiency low entropy homeless camp model. In its most stripped-down form: the Universal Energy Tax "UET" is based on the principle.
Truth Efficiency = Useful Information / Total Energy Expended
The success of very #newsroom, #classroom, and social service depends on that ratio. This may be how assistance for the #homeless should be organized; students, hikers, bikers, travelers. In this case it represents #brain to compute efficiency-mwh
Did you ever ride the teacups at Disneyland? Me? I’m not sure. I know I went there once as a child and saw the teacups spinning like pastel whirlwinds, but I don’t recall actually getting on the ride. We were there for the Matterhorn, I think—but that too is a wisp in memory, a snow-globe shaken and faded with time.
It’s one of those things: you feel certain you’ve got a grasp on the past, but there’s always the chance the memory is wrong. Our minds are tricky. Hmm... I could’ve said “brains” there, in the not-hungry zombie sense.
Is there a difference between brain and mind? My take: the brain is the hardware, the mind is the software—or maybe the app. The brain runs the body’s systems, while the mind handles thought, ideas, dreams, fears, memories, and self-awareness. There’s overlap, of course, and I’d argue you can’t have one without the other. Except—there’s no thinking without a brain. But you could still have a non-thinking brain. Me thinks.
So what happens when the brain stops functioning completely—when it dies? Logically, the mind, the consciousness, vanishes. Poof. Gone. Not here anymore. Doesn’t exist. Ashes to ashes, dust to dust.
But... is there more? It’s comforting to think so, even if it’s not logical—unless you’re in a science fiction story where minds are freed from the burden of biology and float off into the cosmos. Anything is possible, I suppose. Maybe that’s where belief steps in—to help us embrace the illogical with open arms.

"A green anole (Anolis carolinensis) clings vertically to a weathered redwood post, its body stretched in a head-down pose that suggests both alertness and ease. The lizard’s skin gleams with a vivid, almost tropical green—smooth and unblemished, like a fresh leaf after rain. Its limbs extend outward with delicate precision; each toe tipped with adhesive pads that allow it to defy gravity on the post’s upright surface.
The redwood post itself is aged and textured, its grain running vertically in soft striations of reddish-brown and gray. Faint cracks and sun-bleached streaks give it a sense of quiet endurance, like a sentinel in the yard. The anole’s tail curves upward in a gentle arc, echoing the post’s vertical rhythm and adding a sense of motion, as if the lizard is mid-pause between movements.
The background is bright and overexposed, rendering it a soft wash of light that isolates the subject—lizard and post—like a portrait against a glowing canvas. The scene feels intimate and ceremonial, a moment of stillness in the daily choreography of a creature perfectly adapted to its perch." - Microsoft Copilot with edits by the photographer
Lab-grown brain tissue is too simple to experience consciousness. Would we even be ready for it? @LiveScience has more, including the ethical debate surrounding “brain organoids.”
Cellular Senescence and Brain Aging: Mechanisms, Therapeutic Strategies, and Implications for Neurodegenerative Diseases by Gaurav Gupta, 2025
In Cellular Senescence and Brain Aging, leading scientists and experts examine
how brain aging relates to senescent cells in the body. This book combines cellular biology and neuroscience, combining molecular, experimental, and translational information.
All these chapters highlight the connection between aging brain cells and the brain’s environment, disclosing the reasons behind neuroinflammation, dysfunction in brain connections, and the death of brain cells.
The book examines the cellular senescence in brain aging processes and its effects on three major neurodegenerative conditions: Alzheimer’s disease, Parkinson’s disease, and Huntington’s disease. It discusses basic aging mechanisms, including oxidative stress, mitochondrial dysfunction, and neuroinflammation, before moving on to current treatments such as senolytics and autophagy modulators.
The book is divided into several chapters, with specific sections dedicated to experimental approaches, detection methods, and disease-by-disease analysis of cellular senescence effects. A specific chapter explores the clinical potential of senescence-targeting therapies and discusses upcoming study pathways.
This publication is aimed at researchers in neuroscience, clinicians, graduate students, neuroscientists, and neuropharmacology professionals involved in the assessment of age-related disorders. It delivers thorough expertise by combining research evidence on brain aging with methods to combat cognitive decline. The structured system within this publication creates connections between basic research and medical implementation, providing essential knowledge for treating neurodegeneration.
