This paper answers why confident idiots run the world.
Cornell University published a psychological paper that explains every terrible boss, every loud influencer, and every broken corporate hierarchy.
It’s called “Unskilled and Unaware of It.”
they tested participants across logic, grammar, and humor to measure the gap between actual performance and self-perception.
And the results are wild.
participants scoring in the bottom 12th percentile consistently believed they were operating in the 62nd percentile.
they were not lying. they were literally incapable of recognizing their own incompetence.
the paper revealed a brutal paradox:
the exact skills required to master a domain are the exact same skills required to accurately evaluate your own competence in that domain.
if you lack the skill, you inherently lack the cognitive capacity to realize you are failing.
this creates a dangerous systemic loop.
the incompetent are blessed with absolute, blinding certainty. their brain protects them from their own ignorance, allowing them to speak first, demand authority, and never second-guess their decisions.
meanwhile, the actual experts suffer the exact inverse.
top performers in the study consistently underestimated their rank. because a task was easy for them, they falsely assumed it was easy for everyone else.
they hesitate. they obsess over nuance. they assume they have nothing unique to add.
we are biologically wired to confuse confidence with competence.
the loudest person in the room gets promoted, gets funded, and gets the microphone, not because they know what they are doing, but because they are physically incapable of seeing what they don't.
the only defense mechanism is building systems that stop rewarding absolute certainty and start demanding proof of work.

"Lautaro Martinez"
Porque la FIFA mostró el gol de Lautaro Martínez ante Inglaterra desde una cámara exclusiva.
Very happy to coordinate this course again. Congratulations goes also to the outstanding instructor team @mjborgnia @LisandroHOtero1 @marianodella @flecumberry @IhNa24104251 Rodrigo Portugal, Judit Lisoni, the @cime_conicet team and to the motivated students that made this course a real success!
Thanks @UNUBIOLAC for the great support to the first two editions of the CryoEM LATAM School. Third one in progress!
UNU-BIOLAC congratulates Dr. Virginia Albarracín and the teams at CIME, UNT, and CONICET for the successful organization of the II Latin-American School on Cryo-EM, advancing scientific training and regional cooperation in biotechnology unu.edu/biolac/news/turning-…

ARGENTINA: EL 1% DE LA POBLACIÓN POSEE EL 26% DE LA RIQUEZA
La distribución de la riqueza en Argentina exhibe una fuerte concentración. Según datos del World Inequality Report 2026 y CELAG, el 10% más rico del país concentra el 60% de la riqueza total, mientras que el 75% de la población reúne apenas el 19%.
La desigualdad también se refleja en la cima de la pirámide: el 1% más rico posee el 26% de la riqueza nacional. En el otro extremo, la mitad de la población concentra apenas el 4%, una diferencia que refleja la brecha patrimonial en el país.
¿Qué te parecen estos datos? Te leemos en los comentarios.

Fantastic symposium on protein cryo-EM at the SAMIC Congress! Inspiring talks and exciting discussions with leading experts from Argentina 🇦🇷, Brazil 🇧🇷, Chile 🇨🇱, and Uruguay 🇺🇾. Great to see the cryo-EM community growing stronger across Latin America!

This is a legitimately amazing paper. TL;DR: They made a microfluidic chip that can trap a million individual cells, hooked it up to a microscope, and used it to connect genetic circuits --> single-cell behaviors.
Say you want to build a complicated gene circuit, like an oscillator with a period of six hours. Normally, you’d make a design, put it into cells, watch it fail, redesign it, and try again.
With this system, you can instead make a million variants in a single tube, introduce them into cells, and trap those cells in the chip to see which designs work. You can then pull out a “winning” cell using optical tweezers, or identify which gene circuit it received via in situ sequencing.
(Each circuit carries a short genetic barcode. You sequence the gene circuit variants beforehand to link each barcode to a design. Then, reading those barcodes inside the chip, using in situ sequencing, tells you which circuit each cell received.)
This is a much more scalable way to test and optimize complex ideas in synthetic biology; not only gene circuits, but perhaps also metabolic pathways. I suspect it’ll be super useful for collecting data for predictive AI models, too. Congrats @NoahOlsman!

🧫 Biologists (065/BI/2026): how do bacteria get into human cells? Study cell entry with a natural model, the midbody remnant, a bacterium-sized particle released at every division, using AI-guided microscopes, and compare it with S. aureus.

Las niñas también aprenden de lo que ven.
Cuando ven a mujeres alzar la voz, romper estereotipos y perseguir sus metas, descubren que ellas también pueden hacerlo.
Que ninguna niña crezca pensando que hay sueños que no son para ella.

ゲノム編集を特定の部位(臓器や組織)内でのみ誘発するために、光に反応して活性化するCRISPRの系を構築、マウスに投与、超音波で光を発するセラミック粒子を投与、超音波を当てたところだけゲノム編集が起こる系を開発したというCELL誌論文の紹介記事。Nature。

En Argentina hay 61 universidades; de ellas, solo 53 reportan cifras. Cuando las analizás, encontrás diferencias enormes.
Algunas gastan $812.957.362 por egresado, mientras otras solo 30. Unas egresan 5 alumnos cada mil estudiantes y otras piden presupuesto mientras gastan USD 98,6 millones en estudiantes extranjeros.
Hoy sumamos en @DatosHoyARG una nueva herramienta: el Monitor de Universidades Argentinas (datoshoy.com/universidades).

La IA ya ha roto el monopolio del conocimiento del especialista. Lo que queda es el juicio y la capacidad de integrar lo que no está en ninguna base de datos.
Muy recomendable esta perspectiva en @NEJM sobre por qué el generalista (y las humanidades) merecen una revalorización.
