‘Life is a Miracle,’ but learning from disasters isn’t: Lessons from Japan’s 2011 earthquake and tsunami Memorials, monuments, preserved school buildings and found objects form part of a memory culture that keeps conversations about risk reduction going.

"As the 2011 #tsunami showed, physical infrastructure alone cannot eliminate risk. People’s risk awareness, preparedness and willingness to act swiftly — often informed by local knowledge and disaster education — play decisive roles in preventing loss of life." ⚒️

Fukushima Daiichi today: a landscape marked by the legacy of #disaster.

15 years ago, a devastating magnitude 9 #earthquake and #tsunami triggered one of the worst nuclear catastrophes in history. Today, the site of #Fukushima remains surrounded by rows of contaminated water tanks and deposits. ⚒️

The greatest risk of AI in higher education isn’t cheating – it’s the erosion of learning itself Automating knowledge production and teaching weakens the ecosystem of students and scholars that sustains universities, raising existential questions about their mission.

Keep calm and be transparent: advice from scientists who retracted their papers Retractions correct the scientific record, but they have stigma attached to them. Some in the research community want that to change.

Interesting piece in @nature.com about authors that have self-retracted their scientific paper: this may be very positive, for science and even for them. ⚒️ 🧪

Attaques contre les sciences et l’Université aux États-Unis et en France: comprendre les stratégies, cibles et effets et lancer des les mobilisations à venir en France, en écho à celles prévues aux États-Unis.

Can we tell if an earthquake is going to be a foreshock? A recent study says yes, but we find otherwise.

Will a large earthquake be followed by an even larger event? A 2025 paper proposed a new method for classifying foreshocks in advance, with an apparent success rate above 90%.

But does it work?

Our deep-dive analysis found serious problems that we believe invalidate the result. Read more:
