I was on a train in Tokyo. We stopped between stations. Announcement in Japanese, then in English: "We apologize for the delay. We will resume shortly."

The delay was maybe 3 minutes. Not a big deal.

When the train started moving again, another announcement: "We sincerely apologize for the delay. We were stopped for 3 minutes and 20 seconds. This is unacceptable. Thank you for your patience."

Three minutes and twenty seconds. They measured it exactly. And called it unacceptable.

When I got off at my stop, there were station staff on the platform bowing and handing out delay certificates.

I took one out of curiosity. It was an official document stating that the train had been delayed by 3 minutes and 20 seconds, signed and stamped.

The staff member said in English "for your employer. So they know the delay was not your fault."

I said I'm a tourist, I don't need it. He looked confused. "But the delay affected you. You deserve an apology."

Three minutes. They were treating a three-minute delay like a major incident.

Later I mentioned this to a Japanese friend. They said "oh yes, delay certificates are normal. Trains are supposed to be exactly on time. If they are late, they must apologize."

I said three minutes isn't late, it's nothing. My friend said "in Japan, three minutes is late. On time means on time. Not approximately on time."

They said the train company probably investigated why there was a 3-minute delay. "They will find the cause and fix it so it doesn't happen again."

I kept the certificate. It's framed in my apartment now. A reminder that somewhere in the world, people care about three minutes.

Scientists have created one of the most detailed 3D reconstructions of a human cell (eukaryotic cell) ever produced.

This groundbreaking model, often termed a "Cellular Landscape Cross-Section Through a Eukaryotic Cell," combines data from X-ray tomography, nuclear magnetic resonance (NMR), and cryo-electron microscopy to map molecular structures in extreme detail.

La ENIAG es la primera encuesta de su tipo en México sobre el uso de #inteligenciaartificial 🤖 en #educación superior🎓, realizada por la SEP. Los resultados revelan cómo estudiantes y docentes se están adaptando a esta transformación.
¿Para qué se utiliza?🤔 Te contamos👇🏻

@Jesus_lcoe @jmatuk Totalmente de acuerdo. La falta de cobertura mediática de una obligación chafa como es esta, no solo deja nuestra información al descubierto, también generará mayor rezago. Toda esta gente en zonas lejanas se enterarán hasta que les corten la línea y se queden sin internet.

Pressure to publish jumps. And researchers have no time to do science.
(New survey from Elsevier)

Survey of 3200 researchers:

1. Only 45% of scientists have sufficient time for actual research.

2. For 68%, the pressure to publish today is greater than 2-3 years ago.

3. 29% of researchers are considering relocating to another country (for better funding, work‐life balance, or greater research freedom).

4. 58% of researchers use AI tools in their work.

5. Reported benefits from AI: saving time (58%), helping with literature summaries (61%), literature reviews (51%), data analysis (38%), drafting proposals (41%), and drafting papers (38%).

Globally, life in academia is getting worse.

For students & postdocs - it’s especially hard to decide on an academic career.

❗️ A few days ago, I gave a lecture on this topic.

“PhD: Dreams, Reality and Consequences”

No creo que sea normal, pero sí es algo que ocurre en todo el mundo. El fenómeno no es exclusivo de México; sin embargo, me preocupa profundamente que tanto las empresas como los gobiernos —en los tres órdenes— nieguen la existencia de estas brechas.

El INAI no era perfecto, pero me consta que daba seguimiento a las filtraciones y que en su momento sí hubo sanciones contra organismos que violaron las leyes de protección de datos personales.

Hoy, en cambio, no veo ningún tipo de seguimiento. Incluso —y lo digo con toda sinceridad, sin exagerar— hay una persecución más fuerte contra quienes alertamos sobre este problema que contra quienes lo provocan.

⚠️ | Cae página para denunciar suplantación de REPUVE en sitios oficiales de CDMX

Desde ayer se envió un correo a @LaAgenciaCDMX para denunciar que un dominio oficial del @GobCDMX era suplantado para robar con trámites falsos de REPUVE.

La agencia contestó que se hiciera el reporte en el sitio de denuncia digital, operado por ellos mismos, pero...

¿Qué creen?

Al igual que los otros sitios con dominio de CDMX (Llave CDMX, C5, etc.), la página estaba caída y era imposible denunciar.

Así estuvo por varias horas, e incluso actualmente hay quienes no pueden ingresar... ⬇️
