"Keiner hat Zeit, jeder andere Vorlieben und es wird ständig gemotzt. Trotzdem ist das gemeinsame Essen am Familientisch heute wichtiger denn je. Es spendet Glück, Identität, Trost – und hält nicht nur Familien, sondern auch die Gesellschaft zusammen. Ein Plädoyer." https://www.sueddeutsche.de/magazin/essen-und-trinken/familie-essen-szm.95757?reduced=true

The brain region associated with moral inconsistency

Why don't some people practice what they preach? Researchers reveal that a brain region called the ventromedial prefrontal cortex (vmPFC) is involved. The researchers used fMRI imaging to identify brain activity patterns associated with moral behavior and judgment. People who behaved dishonestly despite judging the same behavior as immoral in others had less activity in the vmPFC, and when the researchers stimulated participants' vmPFCs, they became more morally inconsistent. The work is published in the journal Cell Reports.

"Les résultats confirment qu’à niveau de diplôme, âge, secteur d’activité, profession et autres caractéristiques observables données, l’absence d’autonomie au travail renforce nettement l’abstention aux élections. Pour les salarié.es qui votent, la possibilité de s’exprimer sur leur travail dans le cadre de réunions formelles contribue à orienter leur vote vers les candidats du centre (macroniste) ou de gauche, et les éloigne du vote RN" https://ires.fr/wp-content/uploads/2024/02/DdT_T_Coutrot_2024_2.pdf

"Inequality has boomed so much in the 2020s that a 2 percent wealth tax on multimillionaires initially introduced in 2021 would yield more than twice as much revenue today." https://prospect.org/2026/03/27/billionaire-wealth-has-doubled-so-far-this-decade/
Billionaire Wealth Has Doubled So Far This Decade

An estimate of a new wealth tax proposal shows that it would generate twice as much revenue as it did when it was first introduced in 2021.

"Writing compels us to think — not in the chaotic, non-linear way our minds typically wander, but in a structured, intentional manner. By writing it down, we can sort years of research, data and analysis into an actual story, thereby identifying our main message and the influence of our work. This is not a philosophical observation; it is backed by scientific evidence. Handwriting can lead to widespread brain connectivity and has positive effects on learning and memory." https://www.nature.com/articles/s44222-025-00323-4
