La misión Artemis II despega esta noche (00:24 hora peninsular) y marcará un nuevo hito en la exploración espacial 🚀
🇪🇸 España forma parte de este momento histórico y será un actor relevante.
Te explicamos por qué 👇🧵
Històricament, el nostre sistema educatiu ens ha avaluat per les respostes. Jutgem l’alumne per com respon les preguntes de l’examen, però no és habitual avaluar algú per les preguntes que fa.
"Espavila, aprèn a preguntar"

Introducing the world's smallest, fully programmable, autonomous robots. Created by Marc Miskin of @Penn_ESE and David Blauuw of @UMengineering, the microscopic robots can independently sense and respond to their surroundings, operate for months and cost just a penny each.

A 17-year-old just built a mind-controlled prosthetic arm for $300.
Yes, $300.
For something that usually costs $450,000.
Let that hit you.
A teenager, working from home, used AI, cheap materials, and 23,000 lines of code to build a device that reads brain signals without surgery, without implants, and without a $450K price tag.
This is not a feel-good story.
It’s a warning shot.
How can a high school student build something 1,500× cheaper than the industry standard?
What does that say about innovation?
About pricing?
About who gets access to life-changing technology?
Of course, medical prosthetics are expensive for real reasons:
materials, testing, regulation, customization.
But let’s be honest — not all of that justifies a half-million-dollar price.
This story exposes a simple truth:
The future of accessibility won’t come from the system.
It will come from the outsiders who dare to challenge it.
If a 17-year-old can match top-tier prosthetics for a fraction of the cost…
why aren’t these solutions available to the millions who need them?
What do you think — breakthrough moment or the start of a bigger revolution?

I thought House of Dynamite, the new nuclear thriller on Netflix, was amazing. Edge of your seat tension throughout, almost documentary-level realism, and the reality of fog-of-war decision making will keep you thinking and talking for long after the credits roll.
