Biological neuron compared to the artificial neuron used in neural networks.

- The top shows a biologic neuron: dendrites receive signals, the cell body processes them, the axon transmits the signal, and terminals pass it onward.
- The bottom shows an artificial neuron: inputs x₁ to xₙ are weighted by w₁ to wₙ, summed with bias B, then passed through activation function f to produce output. This model is the basis for artificial neural networks.

It drives applications such as image classification in social media and voice recognition in virtual assistants.

Esta clase de Stanford de Robert Sapolsky cambió mi forma de pensar.

1 hora sobre el mayor error mental que cometes cada día sin darte cuenta.

Te lo explico con 5 ideas, pero merece la pena verla entera 🧵:

this could be the breakthrough to making robots 10x more affordable

MIT just made an artificial muscle that moves exactly like the real ones in your arm.

a soft fiber sits in a charged liquid, a tiny pump runs a charge through it, the charged particles shift, and the fiber squeezes and relaxes.

it's the same motion as you flexing your arm, except there's no motor, no gears, and no noise.

now, the reason this could be huge for robotic economics:

today every joint on a robot moves with its own electric motor and gearbox.

a humanoid can have 30 or 40 of them, and they're expensive, heavy, and loud.

those motors are one of the biggest reasons a robot costs what it does.

and they scale horribly.

if you want a joint to push harder, you have to swap in a bigger, more expensive motor, so the price jumps every time you want more strength.

the artificial muscle works the opposite way:

to make it stronger you just bundle a few more cheap fiber strands together the way real muscle does, so strength goes up while the cost barely moves.

interestingly, a similar economic flip happened with computers.

early computers filled whole rooms because they ran on thousands of vacuum tubes, which were big, hot, expensive, and always burning out.

then the transistor did the same job in something tiny and cheap, and once you could add more of them for almost nothing, computers went from machines only governments could afford to the phone in your pocket.

motors could be the vacuum tube of robotics, and this muscle the transistor.

if it holds up outside the lab, the most expensive part of a robot gets a lot cheaper

which could move robots toward something every small business or household can afford.

still lab-stage, but a situation worth monitoring!

Dos kiwis al día subieron la densidad de la piel un 50% en ocho semanas en un ensayo, por la vitamina C que dispara la síntesis de colágeno. Me fascina cuánto se mueve la fisiología con cosas baratas y aburridas que ya tienes en la nevera, más que con cualquier crema cara.

ETH Zurich just open-sourced their entire 2026 robot learning course.

Not a MOOC. The actual course. Slides, lecture recordings, coding assignments, GitHub repo.

The curriculum goes from imitation learning and RL all the way to Vision-Language-Action models and foundation models for robotics.

Guest lectures from the co-founder of Physical Intelligence. The creator of Diffusion Policy. Pieter Abbeel. Dieter Fox.

12 weeks. Free. No signup.

If you want to understand where robot intelligence is actually heading… this is the reading list the field is using right now.

Fable 5

[Claude @claudeai]

Fable 5 is state-of-the-art on nearly all tested benchmarks, with exceptional performance in software engineering, knowledge work, scientific research, and vision.

The longer and more complex the task, the larger Fable 5’s lead over our other models.

@wander_investor That happens when passport bros , scumbags, fly to other countries looking for drugs and prostitution..... even they look for minors.... That's disgusting..... You should be in jail

The Senegalese 🇸🇳 delegation gets this treatment on arrival in the USA. Full tarmac searches, shoes off, bags turned inside out like criminals.

This is straight up humiliation and a disgrace. They’d never put white boys through the same.
