What if consciousness is just a prediction loop? Lőrincz et al. (2003): one layer predicts the next input, another computes the error against reality. Copying human output isn't enough; architecture may be the real line. #Consciousness #AI #Philosophy

A pair of galaxies called NGC 6670 overlap in this Hubble image. They appear edge-on, and though they look very close to each other, the two galaxies' nuclei are actually 50,000 light-years apart! NGC 6670 is ~400 million light-years away: go.nasa.gov/4ygu3GU

How do you retune a dark matter detector without moving its walls? Near absolute zero, sliding metal parts seize. So engineers slide alumina rods into a rigid copper cavity. The rods shift its frequency and even boost signal quality. #Physics #DarkMatter #Axions

Your tongue is covered in tiny spikes, and in rats some of them flip direction. At a bump mid-tongue, the papillae grow large and point forward to pin food against the palate for crushing, then angle back to sweep it toward the throat. #Biology #Anatomy #Science

Did you run the Chicago Marathon? Your brain is going to be a little off afterward, and that's okay. I've run 4 marathons, and after every one my brain feels like mush for a few days. Two studies from the same research group help explain why. The first one found that brain myelin drops after a marathon. Myelin is the fatty insulation around nerve fibers that helps signals travel efficiently. Levels came back to normal after about a month. One idea is that late in the race, when glucose runs low, the brain may burn some of those fats as backup fuel. The follow-up study tested brain function in 43 marathon runners and 29 non-runners. Everyone was tested before the race, within 48 hours after it, and again a month later. Basic neural signaling held up. There was no sign that nerve signals were slowed, even with less myelin. Basic visual and motor tasks, attention and executive tasks were all fine too. But two tougher thinking skills dipped for a short time. Processing speed lagged, and so did the ability to tune out distractions and stay on the right answer (the Stroop test). By one month, everything had returned to normal. My take is that the marathon brain isn't damaged… but it’s metabolically stressed and adapting for a while. It protects the essential stuff and lets the demanding stuff slide. Your recovery should include your brain, not just your legs.

Perseverance has set a new off-world record! 🏅 On Oct. 11, the rover's odometer hit 28.10 miles (45.22 kilometers), eclipsing the distance record set by NASA's Opportunity rover. 1/2

Slow breathing changes your heart rhythm, and your brain reads it. Coherent breathing pulls the body out of survival mode. The step pitched here: rehearse the outcome with real gratitude so the body adapts in advance. #Breathwork #HeartBrainCoherence #Mindset

How a camera catches lightning it can't predict: subtraction. It subtracts each frame's pixel brightness from the last. Static clouds and buildings cancel to zero. A bolt is a sudden spike of bright pixels, so it triggers the save. #ComputerVision #Photography #Tech
