Poco a poco se van desentrañando procesos que vinculan lo #geológico, #mineralógico y #geoquimico con lo orgánico, aspectos de indudable interés astrobiológico. Recientemente, #nucleobases en meteoritos y en asteroides y ahora #Curiosity ha detectado orgánicos complejos en #Marte
Japanese collaborators detected all five #nucleobases — building blocks of DNA and RNA — in samples returned from #asteroid #Bennu by @NASA's #OSIRISREx mission.

¿Sabías que, además de numerosos compuestos orgánicos, las #nucleobases (bases nitrogenadas) se han descubierto también #meteoritos, concretamente en #condritascarbonáceas: Murchison, Murray y Tagish Lake? (Oba et al. 2022). Esto tiene importantes implicaciones #astrobiológicas.
Researchers identify #carbonyl adducts of #nucleobases as MR1 self-antigens, suggesting MR1 T cells might scan for #metabolic changes in #tumor cells.

Now in @SciImmunology: Vacchini, De Libero, &al report #carbonyl adducts of #nucleobases are #SelfAntigens presented by #MR1 that activate #MR1TCells! Detecting altered #metabolism may allow #ImmuneSystem to perceive changes assoc w/ #infection & #cancer!

El hallazgo de las 5 #nucleobases en condritas carbonáceas y alguna en asteroides, me parece uno de los descubrimientos más importantes con implicaciones #astrobiológicas. Algo a tener en cuenta en relación con el origen de la vida en la Tierra y su búsqueda extraterrestre

Uracil in the carbonaceous #asteroid (162173) Ryugu: https://t.co/DbAiiBoeMr - "we report the detection of #uracil, one of the four #nucleobases in #ribonucleic acid, in aqueous extracts from #Ryugu samples."
https://t.co/xNjn3AnPD8 proud to present our latest paper in Journal of Nanostructure in Chemistry (Impact Factor 8.0 , @SpringerNature ) on #nanosystems based on #aminoacids carrying #DNA #nucleobases from a collaboration led by CNR @CNRsocial_ https://t.co/tahSMrqCM5
DNA delivery from outer space! Oba et al. @HokkaidoUni in @NatureComms make the fascinating discovery of the presence of #nucleobases #cytosine, #uracil, and #thymine in #meterorites. Recommended by Laurent Villard

A very nice publication by @rociobv and co-workers on the ultrafast deactivation of thioguanine investigated by theory and experiment.
This is the 12th paper of the SI on "Photophysics of Molecular Systems" for @Molecules_MDPI

Getting gas this morning I asked about the “ATGC” on the license plate of the guy right next to me at the pump. His eyes lit up since no one had recognized it before. I live and breath DNA. #nucleobases

Interesting article in #AIP_JCP using transient absorption spectroscopy to determine the electronic relaxation of #DNA-bound silver clusters, suggesting targeted changes to #nucleobases can tune cluster brightness.
