The director of the Brazilian Synchrotron Light Laboratory (LNLS) will give an overview of the facility, the science and user programs; their role in global science production, user training and development in the Latin American and Caribbean region, and in science diplomacy with both the so-called Global North and Global South.
Access to synchrotron facilities provides unique opportunities for the scientific and professional development of early-career researchers, especially those from underrepresented regions such as Puerto Rico. This presentation highlights my trajectory as a graduate student whose scientific path has been enriched through long-term involvement with the Cornell High Energy Synchrotron Source...
The IUPAP–UNESCO International Colloquia on Physics for Society are back for 2026, continuing their mission of connecting physics with the major challenges facing our societies.
The first colloquium of this year’s series, organized in the framework of the International Decade of Sciences for Sustainable Development (IDSSD), will take place online on 8 June 2026 18 CEST (Paris time) and...
Macromolecular X-ray crystallography is a powerful, sensitive technique that allows the identification of ligand-protein complexes, but it depends on crystals of high resolution and high tolerance to inorganic solvents. In this study, we investigated possible alternatives to the sole treatment of schistosomiasis, Praziquantel, by identifying small molecules that can interact with Schistosoma...
The most widely diagnosed disease globally is cancer, and it has been increasing in incidence and prevalence. The Global Cancer Observatory revealed that in 2022, the number of new cases stood at 20 million, and is set to increase by 77.5 % by 2050. The pro-cancer Retinoblastoma binding protein 6 (RBBP6) is a multi-domain protein that contains the Really Interesting New Gene (RING) domain,...
The promotion of synchrotron radiation and in particular of new facilities often requires presentations to broad audiences, illustrating the benefits from its use. However, such presentations systematically encounter a problem: identifying good arguments to demonstrate the practical and financial benefits, in addition to the scientific ones. Until recently, one could not find reliable and...
Several Caribbean researchers and students, including from Puerto Rico, have been conducting materials and biological research studies at synchrotron facilities around the world. However, no synchrotron facility exists in the Greater Caribbean Region. A few years ago, a group of international researchers created the Latin American International Synchrotron for Technology, Analysis and...
The commissioning of the STAR Research Infrastructure (Southern Europe Thomson Back-scattering Source for Applied Research), located at the University of Calabria in southern Italy, is currently in progress. STAR is a compact light source designed to generate monochromatic, tunable, and polarized hard X-ray beams with picosecond pulse duration through inverse Compton scattering (ICS), covering...
The aspiration of establishing a national advanced science facility, particularly a synchrotron light source, in an emerging economy such as Mexico, represents a profound commitment to fostering scientific progress and technological autonomy. Such advanced research infrastructure is widely recognized as the bedrock for a nation's position in global scientific advancement, yet its realization...
A group of researchers in Puerto Rico from public universities (University of Puerto Rico, Río Piedras, Humacao, Cayey, and Mayagüez campuses) and private universities (Universidad Ana G. Méndez, Cupey and Gurabo campuses) has jointly successfully obtained NSF and DOE funding for projects to recruit, retain, and graduate undergraduate and graduate students conducting renewable energy research...
LAAAMP is a Joint Programme of the International Union of Pure and Applied Physics, the International Union of Crystallography, the Abdus Salam International Center for Theoretical Physics, and the International Union of Pure and Applied Biophysics, originally funded by the Grants Programme of the International Science Council.
The Grants Programme creates innovative international...

Phototransferred thermoluminescence (PTTL) is the transfer of optically stimulated electrons from deep saturated electron traps to previously emptied shallow electron traps. Conventional thermoluminescence (TL) of CaGa2O4:Pr3+ shows five peaks of which only three are Phototransferred under illumination by blue light (470nm) for TL measured to 500 oC. Pulse annealing analysis shows all PTTL...
Energy concerns are among the main obstacles to maintaining the viability of our planet and modern life, as fossil fuels non-renewable energy resources remain the primary source of global energy consumption. This study presents a theoretical investigation into the spectral performance of a metamaterial structure composed of tungsten (W) and hafnium dioxide (HfO₂) layers, specifically designed...
Studies on point defects in germanium (Ge) are increasing, primarily because these defects have the potential to modify the electronic and optical properties of Ge, thereby enhancing device applications. While significant progress has been made in defect studies, a comprehensive understanding of defect complexes resulting from interactions between type (Al or B) and p-type atoms (D_GeX_i and...
Reliable decoding of cognitive workload from electroencephalography (EEG) signals is essential for adaptive robotics, neuroergonomics, intelligent transportation, and human–machine interaction systems. Despite recent advances in deep learning, EEG-based workload classification remains limited by poor cross-subject and cross-dataset generalization. In this work, we investigate hybrid Riemannian...
