The University of the West Indies (UWI) has partnered with CCRIF SPC to establish a pioneering postdoctoral fellowship program specifically dedicated to climate change detection and attribution research. This innovative initiative, valued at US$50,000, represents CCRIF’s first direct investment in postdoctoral research and aims to enhance regional expertise in tropical cyclone modeling and climate attribution science.

Dr. Jhordanne Jones, a distinguished UWI alumna and NOAA Climate and Global Change Fellow who serves as a Lead Author for the Intergovernmental Panel on Climate Change (IPCC), has been selected as the inaugural fellow. Her research will develop sophisticated hurricane simulations, analyze damage statistics, and facilitate public engagement activities, positioning UWI and the Caribbean region as significant contributors to global climate science.

Professor Densil A. Williams, Principal of UWI Mona Campus, emphasized the fellowship’s importance: “This investment will enable UWI to develop the specialized expertise necessary to guide evidence-based policy decisions, ensuring our communities can rebuild with greater resilience.”

The program has already yielded significant preliminary findings. Analysis of Hurricane Beryl (2024) revealed wind speeds exceeding historical records, ranking among the top 5% of storms under projected warming scenarios. Research on Hurricane Melissa (2025) demonstrated that climate change contributed to approximately 7% higher wind speeds, 16% increased rainfall, and made rapid intensification six times more likely—highlighting the adaptation challenges facing small island nations.

This fellowship expands upon a longstanding collaboration between UWI and CCRIF that has provided over US$1.8 million in scholarships, internships, and project funding since 2010. The institutions are collectively advancing Caribbean leadership in climate science, resilience finance, and global climate justice advocacy.

Professor Michael Taylor, Dean of the Faculty of Science and Technology and Co-Director of UWI’s Climate Studies Group Mona, noted: “CCRIF’s support for detection and attribution science is truly visionary. By funding research that directly connects extreme weather events to climate change, CCRIF is helping position Caribbean science at the forefront of global climate justice initiatives.”

In a groundbreaking astronomical revelation, NASA’s James Webb Space Telescope has captured an extraordinarily detailed image of the protostar HH 212, located approximately 1,300 light-years away in the Orion constellation. This latest discovery provides unprecedented insights into the early stages of star formation, showcasing symmetric pink ejections that represent material being expelled as the infant star evolves.

The newly released image reveals intricate details never before observed, including remarkably balanced bipolar jets emanating from the protostar’s poles. These jets, extending over light-years in distance, exhibit near-perfect symmetry that has astonished astronomers. The precision of these structures offers crucial evidence about the formation processes of stars similar to our Sun during their earliest developmental phases.

Dr. Mark McCaughrean, Senior Advisor for Science and Exploration at the European Space Agency, emphasized the significance of this discovery: ‘Webb’s infrared capabilities allow us to peer through the cosmic dust that has previously obscured our view of these stellar nurseries. What we’re seeing is essentially the birth process of a star system, with incredible clarity that transforms our understanding of stellar evolution.’

The observation provides critical data for astrophysicists studying how stars accumulate mass and how bipolar jets influence their surrounding interstellar environment. The symmetry observed in HH 212’s jets suggests these processes are far more organized and structured than previously theorized, potentially rewriting established models of star formation.

This discovery marks another triumph for the James Webb Space Telescope, which continues to exceed scientific expectations since becoming operational in 2022. The telescope’s advanced infrared instruments have opened new windows into cosmic phenomena that were previously invisible to ground-based telescopes and the Hubble Space Telescope.

The research team continues to analyze the data from HH 212, expecting further revelations about the physics governing star birth and the formation of planetary systems. These findings could ultimately shed light on the origins of our own solar system and the conditions that make planetary systems habitable.

In a remarkable display of natural predation, a Dominican boa constrictor (Boa nebulosa) was documented consuming an adult iguana (Iguana delicatissima) along Elmshall Road on April 25, 2012. Wildlife observer Arl James witnessed and photographed the entire predation sequence, providing rare insight into the feeding behavior of Dominica’s largest endemic land reptile.

The encounter began when James initially mistook the iguana’s tail for roadkill before realizing he was observing an active constriction event. The boa had tightly coiled around the sub-adult iguana, employing its signature constriction technique to suffocate the prey. After approximately thirty minutes of observation, James retrieved his camera equipment and returned to document the subsequent feeding process.

The predation attracted significant attention from passersby, nearly causing traffic congestion as motorists attempted to photograph the interspecies interaction. Following the constriction phase, the snake methodically uncoiled and began dragging the lifeless iguana away from the roadway into adjacent vegetation.

The boa commenced swallowing the iguana head-first, a process researchers estimate requires approximately one hour due to the prey’s substantial size and elongated tail structure. James documented the initial swallowing phase before departing, capturing the snake having consumed the iguana up to its front limbs.

Scientific context reveals this observation contributes to understanding predator-prey dynamics between these two endemic species. Researchers from San Diego Zoo had previously documented similar predation events through skeletal remains found in 2009, where iguana skeletons were discovered inside boa skeletons, confirming head-first consumption patterns.

Both species possess significant ecological importance: The Dominican boa is a live-bearing constrictor found exclusively on the island, capable of reaching lengths exceeding 10 feet. The Lesser Antilles iguana represents Dominica’s largest lizard species, with males exceeding 3 kilograms. Recent conservation concerns have emerged due to invasive green iguana (Iguana iguana) hybridization threats to the endemic population.

This documentation provides valuable insight into the complex trophic relationships maintaining ecological balance within Dominica’s unique ecosystem, where adult iguanas serve as prey for mature boas while juvenile boas face predation from birds of prey and other predators.
