La rutina y sus sinsabores pueden hacer olvidar lo bonito de trabajar todos los días haciendo ciencia. O contándola, que también. Entonces llega un grupo de estudiantes que preguntan, observan, se asombran… Y recordamos que esto puede ser emocionante, además de útil para la sociedad.
¿A que sí?
Este año, en la Semana de la Ciencia han visitado el CNIO estudiantes de Davante MEDAC de la FP Superior Anatomía Patológica y Citodiagnóstico. ¡Gracias a quienes dedicais un rato a contar vuestro trabajo!


Ana Cuadrado (arriba a la izda) e Isabel Blanco (abajo izda.) recibieron a los estudiantes con sendas charlas divulgativas en el Auditorio. Después, los grupos visitaron el grupo de Telómeros y Telomerasa, donde les atendió Sonia Burgaz (arriba dcha.), y el grupo de Melanoma, con Nuria Gago y Susana García (abajo dcha.) como guías. El destino siguiente, la Unidad de Histopatología, quedó para una próxima visita.

A team led by Prof. Marcos García Suero at the Institute of Chemical Research of Catalonia (ICIQ) has found a way to overcome a long-standing limitation: performing a carbocation reaction in peptides and proteins in aqueous media. The study, now published in Angewandte Chemie International Edition, marks a milestone in the field of for site-selective peptide and protein bioconjugation.
First author Dr. Adriana Faraone reflected on the journey: “What we achieved was to learn how to work with these biomolecules which require different chemical understanding and technical expertise, and we merged organic chemistry with the field of bioconjugation with great results.”
The team’s approach relies on cyclopropenium cations (CPCs), small aromatic carbocations capable of selectively reacting with cysteine residues. This site-selective modification enables the direct installation of tetrasubstituted cyclopropenes, which can serve as a “chemical handle” for further transformations, avoiding the use of metals or hazardous reagents typically involved in similar processes.

Co-first author Matteo Balletti explained, “Our strategy is a new bioconjugation method able to directly insert cyclopropene motifs in complex biomolecules. This could have an impact on the implementation of new bioconjugates—which are synthetically modified peptides or proteins—that can aid the development of peptidomimetic drugs.”
Bioconjugation plays a crucial role in the development of modern therapeutics such as antibody–drug conjugates (ADCs), PEGylated proteins and peptidomimetics. These synthetically modified biomolecules combine the precision of biological systems with the versatility of chemistry, helping researchers design more selective and effective treatments. Discovering new and simpler ways to attach chemical groups to proteins is therefore a key challenge for pharmaceutical and biotechnology research.
According to Prof. Suero, “This discovery extends our cyclopropenium chemistry beyond small molecules, into the realm of biomacromolecule functionalization in physiological media.”
At the start of the project, the team faced significant challenges. Cyclopropenium cations (CPCs) are highly reactive towards water, making their use in aqueous bioconjugation particularly difficult. Initial trials in organic solvents showed promise, but transferring the reaction to biologically relevant conditions required extensive optimisation.
The project also lacked previous in-house expertise in peptide and protein chemistry. Dr Adriana Faraone joined the group after completing her PhD with Prof. Paolo Melchiorre and successfully developed the methodology that enabled CPC-based bioconjugation in water. Dr Matteo Balletti later expanded the study, refining the approach and identifying a complementary thiol–ene bioorthogonal process.
The ICIQ-SO Strategic Funding awarded have enabled the advancement of this project. Launched in 2021 as part of the Severo Ochoa research plan, this initiative supports one-year, high-risk/high-gain research projects (not related to previous research done) to a Group Leader that align with ICIQ’s strategic priorities. This project have received funding from the Spanish State Research Agency / Ministry of Science, Innovation and Universities through the “Severo Ochoa” Centres of Excellence Programme (CEX2019-000925-S, MICIU/AEI/10.13039/501100011033) as well as from AEI (PID2022-140286NB-I00), ERC (865554) and MSCA (101032589)

Abstract: We propose a new pathway to the baryon asymmetry in which small primordial black holes (PBHs) act as localized, short-lived baryogenesis engines after the electroweak phase transition (EWPT). Hawking emission from evaporating PBHs deposits energy into the surrounding plasma, creating over-pressured hot spots that drive near-acoustic shock fronts. Inside these fronts the Higgs expectation value is driven to the symmetric phase while remaining broken outside, yielding moving interfaces that source chiral charge; active sphalerons in the restored regions then convert this into baryon number. We compute the time-dependent Hawking power across Standard Model species, estimate the microscopic Landau–Pomeranchuk–Migdal thermalization length that sets the initial hot-spot size, and solve the hydrodynamics of the expanding front. Adapting electroweak baryogenesis methods to moving walls, we derive the resulting baryon yield for PBH populations with realistic time-dependent mass functions resulting from critical collapse theory. Crucially, the mechanism supplies the needed out-of-equilibrium dynamics without requiring new physics to render the EWPT first order.



Saber más sobre variantes genéticas que aumentan el riesgo de cáncer permite prevenir mejor. Cómo avanza el conocimiento en esta área, y cómo las consultas de cáncer familiar ayudan ya a miles de personas a anticiparse a la enfermedad, fueron temas centrales de la jornada organizada por el Centro Nacional de Investigaciones Oncológicas (CNIO) con ocasión del Día Mundial de la Investigación del Cáncer. Quienes no pudieron asistir presencialmente pueden ya ver la grabación, en CanalCNIO.
Celebrada en CaixaForum Madrid, la sesión permitió a público no especializado escuchar al genetista Ángel Carracedo, coordinador de IMPaCT Genómica, y a las investigadoras Mercedes Robledo, jefa del grupo de Cáncer Endocrino Hereditario del CNIO, y María Currás, jefa de la Unidad de Cáncer Familiar del CNIO. También participaron Rosario Perona, vicedirectora del ISCIII, y José Enrique León, miembro de Amigos del CNIO. Condujo la jornada la periodista de ciencia Pampa García Molina.
“Los programas de cribado de cáncer van a cambiar radicalmente”, dijo Carracedo. “El futuro pasa por que quien quiera se haga un cribado a los 20 años. Si nos anticipamos a la enfermedad, podemos salvar muchas vidas”.
