En el asteroide Bennu se han encontrado todos los componentes del RNA (!!), al menos 14 aminoácidos de los que forman las proteínas, glucosa y otras moléculas prebióticas clave para el origen de la vida.
Ojalá el asteroide (462078)Carlosbriones pueda analizarse algún día... y se parezca a éste 😊

The strain on scientific publishing
Abstract. Scientists are increasingly overwhelmed by the volume of articles being published. The total number of articles indexed in Scopus and Web of Science has grown exponentially in recent years; ...
#QuantitativeScienceStudies #MITpress #Y2024 The strain on scientific publishing direct.mit.edu/qss/article/... Groups have disproportionately grown in their articles published per year. Publishers enabled this growth by hosting “special issues” with reduced turnaround times.

Dramatic fall of submissions at top MDPI journals across the board after IJERPH delisting
Dramatic fall of submissions at MDPI::IJERPH following delisting by clarivate
Aggregate consequences of IJERPH delisting: MDPI paper volume down for first time in history -- source: Clarke & Esposito's The Brief
Sooner or later the reputation catches up with you. And it spells doom.
At some point in 2024, common knowledge of bad reputation started to hit MDPI.
IJERPH -- then the world's biggest journal -- got delisted by Clarivate. Submissions plummeted there and across all MDPI portfolio.

An obviously AI-generated figure with AI slop and fake text all over it, recently published in Scientific Reports.
Since AI slop is again all over Scientific Reports, a thread on the economics of grey-zone publishing.
Why does slop keep getting published? What does it mean for science? How can we stop this?

Lo mismo ocurre con el paquete de revistas Discover de Springer Nature, que ha nacido para quitarle gran parte del pastel a MDPI, gracias a una filosofía similar, pero con el paraguas "Nature". El interés de la ciencia es irrelevante en estas iniciativas empresariales.

Quizás hay que recordar la historia. Scientific Reports nació en 2011 para quitarle gran parte del pastel a PLoS ONE, que a su vez nació en 2006 para financiar las otras revistas de la editorial PLoS. Los intereses de los científicos no estuvieron detrás del nacimiento de estas revistas.

Una nueva categoría que ha aparecido es la de subneptunos, planetas más grandes que la Tierra y más pequeños que Neptuno, un rango que curiosamente no está representado en el Sistema Solar.
