“La profundidad es un lujo.

Terminar un libro. Conversar sin un teléfono sobre la mesa. Dedicar más de diez minutos a reflexionar sobre un problema. Escuchar un álbum completo. Escribir sin interrupciones. Estar en un lugar sin sentir la necesidad de publicarlo.

En un mundo que vende distracción masiva, la atención sostenida se ha convertido en el privilegio de quienes deciden. Y viven.“

@albermadriz @GOfit_es @MADRID La de gente en replys que considera que todos los bikinis son brasileños...
Se puede elegir bikini para nadar por mil razones (todas validas). Muchas lo hacemos porque no llevamos la misma talla arriba que abajo, y es dificilisimo que un bañador nos ajuste bien🤷🏼‍♀️

@ZoeGutier A mi me han llegado a felicitar en restaurantes otros comensales por tener a los niños sin móvil (formales pero con sus risas y barullo infantil esperable...).
Lo normal hace muy poco, convertido en esfuerzo titánico inalcanzable...? 🤷🏼‍♀️😪

Traditional Somali Medicine🧵

There is limited information on historical Somali medical practices. The few surviving details are fascinating.

The most sensational of these is successful brain surgery conducted in Somalia nearly 20 years before the first known case in Europe.

Birds only sing when they feel safe, thus signaling on a deep, cellular level that you are safe too. Their frequencies calm the nervous system, lowering cortisol and anxiety. Birdsong is nature’s medicine.

In einer grossen Studie wurde untersucht, wie sich die Leistung von über 26'000 Schülern in China während 30 Monaten veränderte, wenn sie anfingen, KI-Chatbots zu nutzen.

Ihre Hausaufgaben wurden rund 20% besser.

Sie benötigten für die Hausaufgaben rund 20% weniger Zeit.

Das ist super.

Aber: Bei Prüfungen (wo KI verboten ist) wurden sie rund 20% *schlechter*. Das ist eine massive Verschlechterung.

KI kann Denkkompetenz aufbauen, wenn sie als eine Art Tutor eingesetzt wird. Dann spricht man von kognitivem Scaffolding.

Die Realität ist aber, dass die Strategie des kognitiven Offloading der Weg des geringsten Widerstands ist: Denkarbeit an Chatbots auszulagern, ist instrumentell gesehen rational. Ein Fehlanreiz.

Diese Entwicklung ruiniert Bildung. Und sie ist ein systemisches Risiko: Was passiert, wenn eine ganze Generation noch weniger als frühere Generationen lernt, eigenständig zu denken?

Turnitin has become a lucrative business by selling the promise of certainty in an age of AI uncertainty.

But the evidence keeps reminding us that AI detection is not as straightforward as many institutions would like to believe.

I recently read Lucky E. Atamhenwan’s 2026 paper, How are combinations of human-written words and LLM-generated words by ChatGPT, Copilot, Gemini and Grammarly detected by Turnitin?, and the findings are important for anyone involved in teaching, assessment, or academic integrity.

The study tested 81 scripts with different combinations of human-written and LLM-generated text, ranging from 100% human-written to 100% AI-generated. The AI-generated text came from ChatGPT, Copilot, Gemini, and Grammarly.

One of the key findings is that Turnitin did not flag fully human-written texts. It also did not produce AI scores when only 5% or 10% of the text was AI-generated.

But once AI-generated content reached around 15%, Turnitin began producing AI scores. The problem is that those percentages were often inaccurate.

At lower levels of AI-generated text, Turnitin tended to overestimate AI use.

At higher levels of AI-generated text, Turnitin tended to underestimate AI use.

Even more striking, detection varied depending on the tool used. ChatGPT-generated text, for instance, was often underdetected. In one case, a script that was 100% ChatGPT-generated received a Turnitin AI score of only 60%.

The study also showed that some “humanizing” or paraphrasing tools can significantly reduce detection. In some cases, Turnitin returned 0% AI scores for texts that were originally 100% LLM-generated and then humanized.

AI detectors may provide a signal, but they should never be treated as proof. A Turnitin AI score is not a verdict and should never be a confession!

I think instead of asking: “Was AI used?”, we better ask: “How was AI used, why was it used, and does that use align with the learning goals and policy expectations?”

Large language models offer new opportunities for behavioural science, but their rapid evolution poses serious challenges for research rigour.

We published a consensus-based reporting checklist to improve transparency, reproducibility and ethical accountability of large-language-model-based research in the behavioural sciences in Nature Human Behaviour.

Here is a link to our checklist for research transparents: https://t.co/XH0FxupT6D

It supports researchers in clearly describing how LLMs were used, why specific methodological choices were made, and what steps were taken to ensure responsible research practices.

This project was led by @stfeuerriegel and included a large list of expert coauthors from across numerous fields.

Picture reaching for something on a high shelf and coming up short. You don’t give up; instead, you find a stool, carry it over, and climb up. Buried in that action is something remarkable: You held the goal in your mind, identified what you needed, and executed a plan. No training required.

A study suggests bumble bees can do the same—the first demonstration of this kind of goal-directed problem-solving in an insect.

Trump has just destroyed the US beef industry. No country in their right mind is going to import US beef.

After Trump cut funding for Screwworm monitoring programs, the dangerous flesh-eating parasite has been found in US cattle for the first time since 1966.

Compelling essay by sci-fi writer Ted Chiang on why LLMs are nowhere near consciousness, but why it serves the interests of LLM companies to constantly suggest that they might be.

I've pulled one quote below, but the whole article is worth reading.

🦔UC Berkeley's computer science department just posted its worst failure rates in years. 35.3% of CS 10 students got F's in spring 2026, up from under 10% in prior semesters. Professor Dan Garcia says the primary driver is a "vast increase in academic dishonesty" through LLMs. Students use AI to complete assignments, never learn the material, then fail exams. His office hours, once full, are now empty.

My Take
Companies are firing experienced engineers while the pipeline that produces new ones is being gutted by the same technology. Students use AI to bypass the hard part of learning, show up to exams without the understanding, and fail. One professor discovered a student's linear algebra class had an "open AI" policy for homework and exams. That student then couldn't do basic linear algebra in the next course.

Both ends of the workforce are eroding at the same time. Senior engineers are getting cut to fund AI spending. Junior engineers are graduating without the skills because AI did their coursework. And the companies spending trillions on these tools haven't connected those two facts yet.

Ha fallecido a los 56 años Marjane Strapi, la autora de "Persépolis".

Dice la nota de la familia: "Marjane Satrapi murió de tristeza poco más de un año después del fallecimiento de Mattias Ripa, su marido y el amor de su vida".

🤔SORPRESA‼️ IMPRESIONANTE
Resulta que la plaza del hermano de Sánchez era de libre designación. No por oposición. ¿qué plaza entonces es? ¿La Jueza Biedma en la instrucción designó el tipo de plaza?
Porque entonces, si es de libre designación, por ende, NO es plaza apaga y vámonos. La UCO investigando y nosotros pagando. La justicia perdiendo meses en una instrucción sin sentido lógico. Lo que ocurre en este país es increíble. Y los aborregados, dirigidos por la derecha ultra y la ultraderecha, aplaudiendo con las orejas.
