This text discusses a shift currently taking place in global scientific research driven by coding agents, and how Brazil appears, once again, to be on the sidelines of this development. Available only in Portuguese.
Something big is happening in the global scientific community, and Brazil seems to be left out again
“Zombie” and “ghost” references in AI – how they differ and how they arise
Two distinct types. One type is “ghost citations” (reference hallucinations), one of the most curious and frustrating phenomena in generative AI. Basically, the AI invents an author, a book title, or a web link that appears entirely legitimate but does not exist in the real world. The other, “zombie citations,” arise because they perpetuate references to real authors who were retracted [whether deleted or not] from the original databases, and due to shortcomings in programs like Google Scholar, they continue to be cited. Available only in Spanish. … Read More →
Diogenes’ lantern and the researcher’s self-examination: scientific integrity under pressure
Using the metaphor of Diogenes’ lantern, Ricardo Limongi and Marcio Pimenta discuss contemporary scientific practice. More than merely offering a critique, the image of the lantern invites a deeper reflection: how to turn the light inward, engaging in self-examination, ethical responsibility, and integrity while confronting a context that is often unfavorable to researchers in Brazil. … Read More →
SciELO and Crossref are joining forces to spotlight the Brazilian open research community next March
After hearing strong interest from the community in the region during the first Crossref Metadata Sprint, we wanted to bring the opportunity to participate and co-create directly to Latin America. Brazil’s rich experience as a leader in open research sharing offers a unique groundwork for the success of the event, happening in São Paulo, from March 4-6, 2026. … Read More →
Scientific Integrity in the Age of AI and the challenges of transparency: Fraud, manipulation, and the new transparency challenges
Artificial intelligence radically transforms the challenges of scientific integrity. From paper mills to automated fraud generation, we face a crisis that requires new forms of transparency, detection and governance to preserve trust in science—combining technology, institutional reforms and international cooperation. … Read More →
Ofelia Sepúlveda and the library as an extension of our minds
Ofelia Sepúlveda passed away in Santiago, Chile, on November 17, at the age of 95. Of Chilean origin, Ofelia Antonia Sepúlveda Contreras became closely connected to Brazil over her 25 years living there as an international staff member of PAHO/WHO, working at BIREME, where she coordinated the Network of Health Sciences Libraries and Documentation Centers and, later, the Latin American and Caribbean Health Sciences Information System, one of the center’s key functions. … Read More →
Bad science—what’s next?
The dissemination of dubious quality research is a problem that is increasingly worrying scientific journals editors. The various cases during the covid-19 pandemic have put the problem on everyone’s radar. The need to discuss this issue is becoming more and more pressing. … Read More →
AI chatbots and the simulation of dialog: what does Bakhtinian theory have to say?
Proposal of a model for the discursive analysis of interactions with AI chatbots in the light of Bakhtinian concepts in which a controlled polyphony is observed, where all voices are reconciled in a “simulated dialog” that can impoverish critical thinking. We advocate the urgency of AI literacy development considering its ideological, political, and educational implications. … Read More →
International Metrics Make Latin American Urban Journals Invisible
Study shows how global scientific evaluation criteria put urban journals from the Global South at a disavantage, reinforcing epistemic inequality in the production and circulation of knowledge. As an alternative, databases such as SciELO and Redalyc have proven to be auspicious in increasing the visibility and recognition of local scientific production. … Read More →

Metamorphosis, friction or symbiosis between body and animated forms in the work of Ilka Schönbein
The works of puppeteer and dancer Ilka Schönbein challenge perceptions of life and death, provoking reflections on eroticism and finitude. Her creations reveal a poetic singularity that provokes disquieting strangeness in the relationship between the human and the animate. … Read More →
Presence as a field of research in the performing arts

The program includes analyses, discussions and a detailed overview of the journal’s social impact, highlighting its importance and activities within the scope of Open Science. … Read More →
An Analysis of the Epistemological Foundations of Machine Learning
Outlined here is a critical review of the logical-epistemic foundations of machine learning, focusing on the limitation of AI systems’ autonomy in generating knowledge. It contrasts this possibility with the theoretical constraints posed by Chaitin’s incompleteness theorem, which argues that AI cannot surpass human cognitive capacity. … Read More →
How to translate academic writing into podcasts using generative AI [Originally published in the LSE Impact blog in June/2024]
One of the benefits of generative AI is the ability to transform one media from text, to speech, to imagery to video. In this post Andy Tattersall explores one aspect of this ability, by transforming his archive written blogposts into a podcast format, Talking Threads, and discusses why and how this could be beneficial for research communication. … Read More →
