Well, this came out today. Terror birds (Phorusrhacidae)were not friends, but food.

Bueno, hoy salió esto. Las aves del terror (Phorusrhacidae) no eran amigos, sino comida. #PaleoSky #Phorusrhacidae #Paleontology #Fossils

#PaleoSky #FossilFriday Very proud of the work made by student Ricardo Gamba on Paleozoic echinoderms, presented at the Geoscience Department of the Universidad Nacional de Colombia. The result of much dedication and discipline.

Trump administration’s pressure on universities echoes past authoritarian efforts in Nazi Germany and the Soviet Union. Over 50 schools face federal probes for alleged discrimination. A comparative and international education expert explains: buff.ly/Qzw1SK5 @isilova.bsky.social, Arizona State 🗃️
Universities in Nazi Germany and the Soviet Union thought giving in to government demands would save their independence
Before the Nazis, German universities were among the best in the world. Step by step, the universities gave up their independence until they were instruments of the state.

Discutiendo acerca de que hacer con la tocineta ahumada que sobró en casa de mi suegra, surgió la idea de hacer una Carbonara.

Este video sobre la receta es oro puro, y los comentarios... ¡Mamma Mia, le comente!🇮🇹🤌🤌

It seems fitting that experts in the study of human evolution were the first to take a bold stand against the misuse of AI in scientific publishing.

A sad end for the JHE. A timely case study for my work on the modern relevance of the earliest knowledge systems.

A sad end for the Journal of Human Evolution
A joint statement announces the resignation of the entire editorial board, while disclosing for the first time the use of AI in article production.

Llevo años, muchos más de los que es decente aceptar, amasando un enorme conjunto de datos. Anoche descubrí que debo recortar dicho conjunto de datos para tener un mejor resultado. Pero no se confundan, es gracias al mismo conjunto de datos que puedo juzgar que debo recortar al conjunto de datos.

Si no sientes el #OrgulloBarroco, es que te falta un tornillo. Pero no te preocupes, que Artemisia Gentileschi te lo pone.
Pintura titulada 'Jael y Sísara' de Artemisia Gentileschi. Una mujer está arrodillada junto a un hombre que yace dormido en el suelo. Ella sostiene un clavo contra su cabeza con una mano y levanta un martillo con la otra. La escena tiene un fuerte contraste emocional y transmite tensión y determinación. Una escena dramática tomada del relato bíblico del Libro de los Jueces.

In a classic experiment, 12 articles were resubmitted to same journals in which they had already been published -
- 3 were recognized as resubmissions. ✅
- 8 of the 9 articles reviewed again were rejected, often due to "serious methodological flaws"! 😮 😕 ⁉️
www.cambridge.org/core/journal... 🧪
Abstract from article titled, "Peer-review practices of psychological journals: The fate of published articles, submitted again" by Douglas P Peter and Stephen J Ceci. Abstract says, "The present investigation was an attempt to study the peer-review process directly, in the natural setting of actual journal referee evaluations of submitted manuscripts. As test materials we selected 12 already published research articles by investigators from prestigious and highly productive American psychology departments, one article from each of 12 highly regarded and widely read American psychology journals with high rejection rates (80%) and nonblind refereeing practices. With fictitious names and institutions substituted for the original ones (e.g., Tri-Valley Center for Human Potential), the altered manuscripts were formally resubmitted to the journals that had originally refereed and published them 18 to 32 months earlier. Of the sample of 38 editors and reviewers, only three (8%) detected the resubmissions. This result allowed nine of the 12 articles to continue through the review process to receive an actual evaluation: eight of the nine were rejected. Sixteen of the 18 referees (89%) recommended against publication and the editors concurred. The grounds for rejection were in many cases described as “serious methodological flaws.”
