Pleased to see the beautiful #MyACSCover of our review of stereoisomerISM published in @ACSPublications, with @MiguelSanzNovo (the artist!) and @DavidSAstro99. @C_Astrobiologia @CSIC

This review confirms that stereoisomerism is a fundamental contributor to interstellar molecular complexity. It is already available in arXiv: arxiv.org/abs/2603.24848 ; and it will appear soon in Open Access in the ACS Earth and Space Chemistry journal (@ACSPublications) (🧵4/4)

We have discussed the mechanisms that can explain the stereoisomeric ratios (OSR) - defined as the column density ratio of the higher-energy isomer divided by that of the lower-energy isomer (🧵3/4 ).

"INTERSTELLAR STEREOISOMERISM”: stereoisomers are molecules that share the same bonding arrangement, but differ in the three-dimensional orientation of their atoms. These are the 16 stereoisomeric pairs detected in the interstellar medium so far (🧵2/4 ):

🚨 NEW PUBLICATION 🚨 "INTERSTELLAR STEREOISOMERISM”: In this review done with @MiguelSanzNovo and @DavidSAstro99 we present the first comprehensive overview of stereoisomerism in the interstellar medium. @C_Astrobiologia @intaespana @CSIC @ACSPublications (🧵1/4 )

🚀🏆 El 17 de marzo participé en la ceremonia de entrega de las #becas de doctorado y posdoctorado de la @FundlaCaixa del 2025. Un reconocimiento a 💯 @BecariosFLC que buscamos cambiar el futuro que viene.

📢 Nuevo artículo‼️Analizamos cómo estudiantes de 4.º y 6.º EP usan datos (mapas, gráficas, textos vídeos) para argumentar 🤔, qué soluciones proponen💡 y qué diferencias surgen según el curso y modalidad de trabajo 🙌🏼 mdpi.com/2227-7102/16/2/321 @MDPIOpenAccess @EducSci_MDPI

‼️Nuevo artículo en @FrontEducation que explora cómo estudiantes de 8-12 años de distintos contextos socioeconómicos abordan un problema ambiental utilizando destrezas STEM para argumentar y resolver el caso: frontiersin.org/journals/edu… @giecmes @TaELH_UAM @FaculEDUAM

¿Se pueden trabajar las CSC con estudiantes de Primaria? ¿Argumentan basándose en pruebas? ¿Proponen soluciones sobre la presencia de fármacos en aguas? ✅ @stuartuam @iguevara_uam @esquivel_uam y yo te lo contamos ⤵️ mdpi.com/3184098 #mdpisustainability @Sus_MDPI

The paper has been accepted in The Astrophysical Journal (@IOPPublishing), and a preprint is already available at: arxiv.org/pdf/2404.03334.pdf @DavidSAstro99 @C_Astrobiologia

🚨NEW RESULT!🚨 In a recent work led by @DavidSAstro99 we have detected for the first time in space the molecule H2CNCN (N-cyanomethanimine), the stable dimer of HCN of highest energy, and the most complex interstellar molecule containing the prebiotically relevant NCN backbone.
