Screenshot of chatbot answer. Verbatim: Yes, Robin, I can include articles available on authors’ personal websites or platforms like ResearchGate, as long as they are openly accessible (i.e., not behind a login or paywall). Here’s how it works: Author’s Personal Websites: If an article is freely available on an author’s website, I can access and cite it. ResearchGate: If the full text is publicly available (not just the abstract or a "request a copy" button), I can use it. However, many ResearchGate articles require you to request access or log in, which I cannot do. Practical Implications for Your Work Since you’re in tectonics and geology, many researchers share preprints or final versions of their papers on personal pages or platforms like ResearchGate, arXiv, or EarthArXiv. I can help you: Find and cite openly available versions of articles. Analyze or summarize content you share with me (even if it’s from a paywalled source). If you’re exploring a specific topic, I can also help you identify open access alternatives or preprints for key paywalled papers. Would you like to test this with a topic or article in your field?
Screenshot of chatbot answer. Verbatim: Yes, Robin, you’re absolutely right. Here’s a clear summary of the situation: Literature Reviews: If you ask me to generate a literature review on a topic, I can only include articles and sources that are openly accessible on the web. Paywalled articles won’t be part of the review unless you provide me with their content or key details. Discovery Limitation: This means you won’t discover or analyze paywalled articles through me unless you already have access to them and share the relevant information. Since you’re affiliated with CNRS, you likely have access to many paywalled articles through your institution’s subscriptions. Here’s how you can bridge the gap: Use CNRS Access: Search for articles using CNRS’s library or journal subscriptions, then share the key points or PDFs with me for analysis. Open Access Alternatives: I can help you find open access versions of articles (e.g., preprints, author’s personal websites, or repositories like ResearchGate). Collaborative Tools: Tools like Zotero, Unpaywall, or Open Access Button can sometimes help locate legal open access versions of paywalled papers.
Screenshot of chatbot answer. Verbatim: Great question, Robin. My training data includes a broad range of publicly available texts up to November 2024, but I do not have direct access to scientific articles behind paywalls. Here’s how it works: Open Access Articles: I can cite and reference articles that are openly accessible on the web, such as those published under open access licenses or available on preprint servers like arXiv, bioRxiv, or institutional repositories. Paywalled Articles: I cannot access or read articles that require a subscription or payment to view. If you provide me with the text or key details from a paywalled article, I can help analyze, summarize, or discuss it, but I cannot retrieve it myself. If you need information from a paywalled article, you can: Share the text or key points with me, and I’ll help you work with that content. Use your institutional access (e.g., through CNRS) to obtain the article and then share relevant details with me.

Copie d'écran de la conclusion de l'article. Le texte dit: Si l’on suit votre analyse, la question prioritaire face à Trump serait donc celle des limites et du rapport de force : il faut qu’un pouvoir établi et crédible — en Europe ou aux États-Unis — lui intime : « C’est assez. » Oui, une telle chose est urgente. Je crois que l’Europe est bien plus forte que les États-Unis et que leurs dirigeants ne le pensent ; mais encore faut-il avoir le courage de voir ce qui se présente face à nous. Les dirigeants européens semblent continuer à croire qu’on pourrait « raisonner » Trump, comme s’il s’agissait d’un interlocuteur classique. C’est une erreur qui nous prive d’une possibilité de sursaut historique. Au contraire, il faut lui poser des interdits avec force. Et il cédera car il ne cède qu’à la puissance — d’où qu’elle vienne et pas seulement à la puissance militaire, dictatoriale ou financière. Le drame, c’est que beaucoup préfèrent céder au délire de Trump, en le croyant le plus fort plutôt que de devenir responsables de leur destin.
Excerpt of JMA leaflet about megaquakes along the northern Japan trench. Text says: In the areas along the Japan and Chishima Trenches, there have been cases where a large earthquake (a subsequent earthquake) followed a magnitude 7 class earthquake. To save as many lives as possible, an "Off the Coast of Hokkaido and Sanriku Subsequent Earthquake Advisory" is issued when an M7 or higher earthquake occurs in or around the probable source region due to the relatively higher possibility of subsequent large earthquakes than usual, despite the low likelihood of occurrence…

Excerpt of the Nobel announcement. It says "Democracy is a precondition for lasting peace. However, we live in a world where democracy is in retreat, where more and more authoritarian regimes are challenging norms and resorting to violence. The Venezuelan regime’s rigid hold on power and its repression of the population are not unique in the world. We see the same trends globally: rule of law abused by those in control, free media silenced, critics imprisoned, and societies pushed towards authoritarian rule and militarisation. In 2024, more elections were held than ever before, but fewer and fewer are free and fair."
