  • OnlyMarms: Wild Marmots Turn to OnlyFans to Fund University Research

    OnlyMarms: Wild Marmots Turn to OnlyFans to Fund University Research

    When university funding cuts threatened a decades-long ecological research project, a University of California Los Angeles (UCLA) biology professor turned to an unexpected platform for support: OnlyFans.

    Dan Blumstein, who co-leads The Marmot Project based in the Rocky Mountains of Colorado, launched the research initiative’s official OnlyFans account under the playful name *OnlyMarms* in late May 2026, aiming to keep his long-term field study of yellow-bellied marmots alive amid shrinking academic research budgets.

    Unlike the adult-oriented content that OnlyFans is widely known for, the OnlyMarms account shares exclusively wholesome, family-friendly content that showcases the daily lives of wild marmots: clips of the fluffy rodents scurrying across alpine meadows, poking their heads out of underground burrows, and basking in warm mountain sunshine. The quirky concept has struck a chord with online audiences, pulling in more than 1,700 loyal fans and generating over $5,000 in direct tips to the project within roughly two months of launch.

    The viral momentum didn’t stop there. Supporters of the project launched a themed memecoin named for OnlyMarms, and transaction fees from the cryptocurrency have added an extra $75,000 in funding for the research, turning a small fundraising gimmick into a major financial boost for the team.

    Blumstein says the idea came to him by chance while he was conducting his routine marmot population count in a Colorado meadow. He had recently watched a television documentary about OnlyFans creators with his wife, and a student working on the project offered the catchy pun name *OnlyMarms* on the spot. One unexpected hurdle popped up during the account approval process: OnlyFans requires all creators to complete age verification, typically via government-issued ID like a driver’s license. Blumstein explained the wild marmots could not meet that requirement, and the platform ultimately approved the unique account after understanding the project’s research mission.

    Building on the unexpected viral success of OnlyMarms, Blumstein’s team is now preparing to host the first ever *Fat Marmot Week*, an event modeled after Alaska’s popular Fat Bear Week. The celebration will highlight marmots’ natural seasonal behavior of doubling or tripling their body mass ahead of winter hibernation while promoting the idea of body positivity.

    While the entire project is lighthearted and has captured global online attention, Blumstein emphasizes that the campaign’s existence points to a growing, serious problem for academic science. As public funding for long-term ecological research at universities continues to be cut, research teams are being forced to turn to unconventional, creative fundraising methods just to keep foundational environmental and biological research projects running.

  • OP-ED: ‘Let’s be objective’ – The most misunderstood phrase in public debate

    OP-ED: ‘Let’s be objective’ – The most misunderstood phrase in public debate

    In the heat of countless public debates, there is a phrase that has become a near-universal conversation ender: “Let’s be objective.” The moment those words leave a speaker’s mouth, a subtle but profound shift occurs. The speaker often straightens their posture, implicitly positioning themselves on higher moral and intellectual ground. Any continued pushback suddenly risks being framed as emotional, ideological, or even anti-scientific. The unspoken message is clear: pure objectivity has arrived, and the argument is effectively over.

    But what exactly does this invocation of objectivity actually bring to the table? The term “objective” stands as one of the most rhetorically powerful tools in modern public discourse. It inherently signals neutrality, and promises distance from personal bias, partisan politics, and individual experience. To claim objectivity is to claim that one’s stance reflects unvarnished reality itself, not just one limited perspective on it.

    Look closer, however, and a curious contradiction emerges. What most people label objectivity often looks far too similar to unshakable confidence in one’s own personal experiences and unexamined assumptions. This question was first explored decades ago by philosopher and psychologist William James, who probed whether a person can feel fully convinced that an idea aligns perfectly with all their existing knowledge, and still be wrong about its objective truth. It is an uncomfortable inquiry, one that forces us to confront a simple, disquieting fact: the feeling of certainty is not the same as the existence of truth.

    This distinction carries particular weight in evidence-reliant fields such as epidemiology, medicine, and public health. These disciplines rightfully center data, statistical inference, and rigorous methodological standards. Their public credibility is built on the promise that knowledge is generated through systematic inquiry, not arbitrary personal opinion.

    Yet knowledge never emerges fully formed from laboratories, untouched by human decision-making. Scientists themselves choose which research questions are worth exploring. Funding institutions decide which projects get the resources to move forward. Researchers interpret results through existing theoretical frameworks that shape how evidence is understood and categorized. Even the selection of a specific statistical model rests on underlying assumptions about how the world works.

    None of this undermines the reliability of science. In fact, it strengthens it. Science functions precisely because it acknowledges the constant possibility of error. It progresses through criticism, replication of results, and ongoing revision. Every scientific finding is inherently provisional, and every conclusion is open to challenge by newer, better evidence. Put another way, science is powerful not because it promises unwavering certainty, but because it has institutionalized the practice of doubt.

    The trouble starts when the language of objectivity is used not as an aspirational methodological goal, but as a tool to shut down intellectual inquiry entirely. This dynamic played out prominently during the global COVID-19 pandemic. Public health communications repeatedly leaned on appeals to “the science,” treating scientific knowledge as a static, finished product rather than an evolving body of work. As new data about the novel virus accumulated, public health guidance shifted and evolved – exactly what should happen when responding to an emerging pathogen.

    For many members of the public, however, these shifting recommendations sparked widespread confusion. Policies that had once been presented as unquestionable, objective fact were suddenly updated. What was actually the normal, healthy process of scientific learning appeared to outsiders as inconsistency. The earlier framing of objectivity as absolute certainty turned this necessary evolution into a perceived contradiction that eroded public trust.

    The real problem was never that science changed – science always changes, and that is by design. The problem was the misleading narrative we had built around what objectivity actually is. When objectivity is framed as a final destination rather than an ongoing process of inquiry, any revision of conclusions looks like a failure instead of the progress it actually is.

    Yet the most robust knowledge systems in human history – from modern scientific inquiry to democratic governance – are built on the core recognition that no single perspective is ever complete. They depend on open disagreement, rigorous public scrutiny, and the constant testing of existing ideas to grow stronger.

    True objectivity, it turns out, may not be found in the bold, confident declaration that one holds exclusive claim to the truth. Instead, it lives in the willingness to continually ask whether we might be wrong. This posture is quieter, less dramatic, and far less satisfying in the heat of a heated argument. But it is also the closest we can ever realistically get to the ideal of objectivity we so often invoke.

    So the next time someone throws out “let’s be objective” to end a debate, the most honest response is neither to concede the point nor dig in for a fight. It is to ask a better question: are we here searching for truth, or just trying to shut down the conversation?

  • Twee Surinaamse wetenschappers gekozen in bestuur Caribbean Food Crops Society

    Twee Surinaamse wetenschappers gekozen in bestuur Caribbean Food Crops Society

    In a historic milestone for Suriname’s agricultural research community, two scholars from Anton de Kom University of Suriname (AdeKUS) have been elected to top leadership positions of the Caribbean Food Crops Society (CFCS), marking the first time the country has secured two simultaneous seats on the regional organization’s governing board.

    The election took place on Thursday during the CFCS’s 58th Annual Conference hosted on the U.S. Virgin Islands. Professor Lydia Ori will serve as CFCS president for the 2026–2028 term, while Dr. Wasudha Malgie will take on the role of board secretary. Joining the new leadership slate are Dr. David Sotomayor, elected vice president, and Dr. Willy Colón, who will serve as treasurer.

    Founded in 1963, CFCS began as a network focused exclusively on advancing food crop research across the Caribbean. Today, it has evolved into a leading regional knowledge hub that brings together academic researchers, university stakeholders, public agricultural agencies, international organizations, private sector representatives, and students to address pressing challenges facing the region’s food systems. Its expanded current agenda covers climate-resilient agriculture, soil management, crop protection, agroforestry, livestock production, aquaculture, agroprocessing, food safety, biodiversity conservation, agricultural biotechnology, precision farming, and circular agricultural practices.

    Each year, the society hosts its flagship international conference, where stakeholders gather to share cutting-edge scientific findings and co-develop solutions for the Caribbean’s agricultural sector. The 59th Annual Conference is scheduled to be hosted by Suriname in 2027, with the 2028 conference set to be held in Jamaica. The theme of Suriname’s upcoming conference is *Exploring New Ways to Cooperation and Partnerships to Strengthen Food Security and Food Safety in the Caribbean Community*, and all preparatory work will be led by the newly elected board including Ori and Malgie.

    The appointments of Ori and Malgie represent a major formal recognition of both AdeKUS and Suriname’s broader agricultural and research sectors. In their new leadership roles, the two scholars will play a strategic, unifying role across the organization, guiding CFCS’s ongoing development, accelerating cross-regional collaboration, and overseeing the execution of the society’s annual conferences.

    During the 58th conference, attendees reaffirmed that coordinated regional cooperation is non-negotiable for strengthening food security across the Caribbean. Priority areas of focus included expanding climate-resilient agricultural practices, scaling innovation and agricultural technology, fostering cross-sector collaboration between research institutions, academia, government, and private industry, supporting early-career researchers, and expanding cross-border knowledge sharing across the region.

    For Suriname, holding top leadership positions within CFCS unlocks significant new opportunities for the nation’s agricultural community. Local researchers and students will gain expanded access to global professional networks, new collaborative research projects, and cross-institutional partnerships, while insights gained through these connections will advance the development of Suriname’s domestic agricultural sector and contribute to stronger regional food security overall.

    The election of the two AdeKUS scholars underscores Suriname’s growing influence within the Caribbean scientific community, and cements the university’s standing as a key partner for regional agricultural research.

  • University of Texas geologists begin study of Dominican Republic’s hydrocarbon potential

    University of Texas geologists begin study of Dominican Republic’s hydrocarbon potential

    A collaborative geological research initiative between the Dominican Republic and the United States has launched a series of on-site field investigations in the Dominican’s southwestern Azua province, focused on unlocking the Caribbean nation’s untapped hydrocarbon resource potential. The project, a formal cooperative venture between the Dominican government and the Bureau of Economic Geology (BEG) at the University of Texas at Austin (UT Austin), brings together leading academic geoscientists and local energy sector specialists to conduct a holistic assessment of the country’s onshore and offshore sedimentary basins.

    Leading the joint expedition are UT Austin geologist Mark Shuster and Dominican energy expert Emilio Núñez. Over the course of their fieldwork, the team has prioritized access to some of the region’s most geologically significant sites, including distinct geological formations across the province and the large Cementos Santo Domingo quarry. At these locations, researchers are conducting detailed studies of the basin’s rock structures, gathering a diverse set of geological samples for laboratory analysis, and measuring key properties that are critical to identifying viable energy reserves. These properties include rock porosity, which determines how much oil or gas a rock formation can hold, and overall mineral composition, which helps contextualize the area’s geological formation history.

    A core focus of the current fieldwork is a set of vintage exploration wells located in the Maleno area. Originally drilled in the late 1930s, these wells have long drawn the attention of geologists and energy investors due to naturally occurring crude oil seeps detected at the site, which signal the possible presence of larger commercial-scale hydrocarbon reserves underground. The current research team is conducting the most detailed modern assessment of these wells to date, updating decades-old data with modern geological measurement techniques.

    All on-site operations are being guided by local geologists from the Dominican Ministry of Energy and Mines (MEM) and technical staff from the country’s National Geological Institute (IGN). During the expedition, the international and local teams have reviewed the full body of data from past exploration efforts in the region, cross-referencing historical findings with new on-site observations to build a more complete picture of Azua province’s complex geological history.

    When completed, the comprehensive assessment is expected to deliver significant long-term benefits for the Dominican Republic. The research will expand and update the country’s national geological database, filling critical gaps in existing knowledge about domestic energy resource potential. By providing accurate, up-to-date geological data, the project will also lay the groundwork for future private and public energy exploration projects, attract targeted international investment in the Dominican energy sector, and support evidence-based policy planning for the country’s energy future.

  • For Women in Science 2026, call for applications opens

    For Women in Science 2026, call for applications opens

    A new opportunity has opened for early-career women scientists across the Caribbean, as L’Oréal Caribe and the UNESCO Office for the Caribbean have officially launched the 2026 application round for the regional L’Oréal-UNESCO For Women in Science programme. This long-running initiative is designed to elevate and support outstanding female researchers in the region, offering two individual grants worth $15,000 each to fuel the advancement of cutting-edge scientific work.

    The application window for the 2026 cohort runs from May 19 to August 14, 2026. Eligible candidates include women scientists based in the Caribbean who are currently enrolled in doctoral research programs, completing postdoctoral work, or in the early stages of their professional scientific careers, across all STEM fields approved under the programme’s framework. On the regional level, the initiative is implemented in partnership with two key regional scientific bodies: the Caribbean Academy of Sciences and the Caribbean Division of the American Association for the Advancement of Science.

    This regional programme forms a core part of the global L’Oréal–UNESCO For Women in Science movement, a decades-old effort founded with the core mission of expanding women’s participation in scientific research and narrowing the persistent gender gap that remains entrenched in STEM sectors worldwide.

    Liana Camacho, Market Vice President of L’Oréal Caribe, emphasized the fundamental value of women’s contribution to global scientific progress. “At L’Oréal Caribe, we firmly believe that science needs the talent, creativity, and leadership of women to address the challenges of today and the future,” Camacho stated. “Through For Women in Science, we seek to increase the visibility of and support women researchers who are generating knowledge and innovation with an impact on our region and the world.”

    To qualify, applicants must be conducting research in one of the programme’s approved fields, which include formal sciences, life and environmental sciences, materials science, engineering, and technological sciences. Beyond providing direct financial support, the awards recognize women researchers working to advance scientific knowledge across disciplines, whose work directly targets solutions to some of the most pressing social and environmental challenges facing the Caribbean region.

    Audrey Azoulay, Director-General of UNESCO, reaffirmed the UN body’s commitment to breaking down systemic barriers for women in STEM. “UNESCO works to recognise and promote the talent of women in science, foster diverse perspectives, and break down the barriers that limit their professional development,” Azoulay said.

    The 2025 edition of the programme offered a clear illustration of the transformative impact of this support, honoring two Jamaican researchers: Dr Lori-Ann Fisher and Dr Arianne Brown Jordan, whose work addresses critical regional health and environmental challenges.

  • Dominican Republic hosts 31st International Congress of Caribbean Archaeology

    Dominican Republic hosts 31st International Congress of Caribbean Archaeology

    SANTO DOMINGO – The Caribbean’s most prominent academic gathering focused on unlocking the history of the region’s Indigenous societies and centuries of colonial rule has officially opened its doors in the Dominican Republic, with the 31st International Congress of Caribbean Archaeology (IACA/AIAC) kicking off in the capital city of Santo Domingo.

    Running through July 18 in Santo Domingo’s iconic Colonial City district, the week-long event has drawn 237 archaeological specialists from 23 countries and territories around the world. The congress serves as a platform for these scholars to share groundbreaking new findings, debate evolving interpretations of the Caribbean’s pre-Columbian societies and viceregal era, and foster cross-border collaboration. All core academic sessions are being hosted at the auditorium of the Dominican Telecommunications Institute (Indotel) Cultural Center.

    The 2024 congress is organized by the Academy of Sciences of the Dominican Republic, in formal partnership with four leading regional cultural and research institutions: the García Arévalo Foundation, Centro León, the Guahayona Institute, and the Casa del Cordón Taíno Cultural Center. Additional institutional and financial support comes from a wide network of public and private entities, including the Dominican Ministry of Culture, Vice Ministry of Cultural Heritage, General Directorate of Museums, the Central Bank of the Dominican Republic, and Banco Popular, among other cultural organizations.

    The academic program is structured across 15 specialized thematic symposia, featuring a total of 97 individual presentations that showcase cutting-edge methodological advances in the field. Research topics span a diverse range of modern archaeological techniques, from ancient DNA sequencing and isotopic analysis to starch grain studies, archaeozoology, archaeobotany, underwater archaeology, and digital heritage documentation using photogrammetry and 3D modeling. Participating researchers hail from many of the world’s top academic and research institutions, including Harvard University, the Max Planck Institute for Evolutionary Anthropology, the University of Copenhagen, the University of Minnesota, and Leiden University, bringing diverse global expertise to the regional conversation.

These include public academic lectures hosted at the Academy of Sciences of the Dominican Republic, guided tours of the Museum of Underwater Archaeology, a hands-on skills workshop at Centro León in the city of Santiago, and a guided on-site archaeological survey at prehistoric sites located within the Cabo Samaná Natural Monument.

    Event organizers emphasized that hosting the congress carries broader strategic and cultural significance for the Dominican Republic. Beyond providing a space for scientific exchange, the gathering strengthens the country’s position as a leading regional hub for archaeological research and international collaborative work, while also raising global awareness of the need to preserve and study the Caribbean’s extraordinarily diverse and understudied cultural heritage.

  • UWI confirms Venezuela quakes caused Cedros coastline rise

    UWI confirms Venezuela quakes caused Cedros coastline rise

    Two of the deadliest earthquakes to hit northern Venezuela in recent memory have left a visible geological mark more than 300 miles away on the southwestern coast of Trinidad, researchers from The University of the West Indies (UWI) Seismic Research Centre (SRC) have confirmed in their first official assessment of the unusual coastal shift. The back-to-back magnitude 7.2 and 7.5 quakes that struck Venezuela last month have killed more than 2,000 people, displaced thousands more as homeless, and left hundreds unaccounted for, with search and rescue operations still ongoing in the hardest-hit La Guaira State. Just days after the large seismic event, residents of Cedros’ Galfa coastline reported a shocking transformation: large stretches of shoreline had lifted nearly instantaneously, leaving hundreds of stranded sea creatures trapped between new rock formations and exposing new sections of previously submerged land.

    Initial on-site observations by geologist Xavier Moonan put the maximum elevation gain from the sudden uplift at roughly 20 feet. Moonan also noted unusual natural oil seeps bubbling up through new shallow rippling pools formed by the shifted terrain. In its preliminary analysis released this week, the UWI SRC confirmed that the extreme coastal movement was directly triggered by energy from the Venezuelan twin earthquakes, drawing a parallel to similar geological fracturing that followed a large 6.9 magnitude quake near Trinidad in 2018.

    Trinidad’s southern coast sits atop a major east-west geological formation called the Southern anticline, a folded rock system crisscrossed by active faults, the SRC explained. This structure creates a linear geological corridor along the south coast that allows pressurized water, oil, and gas trapped deep below the surface by tectonic plate movement to rise toward the crust, resulting in a dense concentration of mud volcanoes across the region.

    Mud volcano formations are defined by fluid-saturated substrate close to the surface, which gives the surrounding ground very low shear wave velocities. Because shear waves—one of the primary types of seismic energy generated by earthquakes—travel far slower through softer, less compact rock and sediment, these geologically unique areas become far more sensitive to shaking from large distant earthquakes, the research team noted.

    The two Venezuelan quakes occurred along the same interconnected fault system, shared nearly identical focal mechanisms, and struck within minutes of one another, meaning they can effectively be treated as a single massive seismic event that produced more than 10 minutes of continuous shaking across the region. Testing at the L’Envieuse mud volcano near Icacos, just west of Cedros, found the natural fundamental vibration frequency of the local geology before the quake was exactly half the frequency of the seismic waves from the Venezuelan earthquakes. This resonance effect amplified the shaking energy, reactivating subterranean mudflows and triggering the sudden coastal uplift seen in Galfa.

    “These unique geological responses are to be expected on Trinidad’s south coast and other regions with similar geology after large magnitude seismic events,” the SRC assessment noted. “As such, targeted efforts must be made to mitigate future risk to lives and livelihoods located in these geologically susceptible areas.” The center plans to release a full, comprehensive report after completing additional on-site testing and data analysis.

    This is not the first time large seismic activity has triggered extreme coastal and land movement in Cedros. In August 2018, a 6.9 magnitude quake centered off Trinidad’s coast caused widespread infrastructural damage across the island, with tremors felt as far away as Barbados, Guyana, St Lucia, and Venezuela. In Cedros, the shaking fractured large sections of land, crumpled key roadways, and cut off dozens of farmers participating in a local food production project from their agricultural plots in the Los Iros area. Farmers reported massive ground cracks that swallowed farming equipment, destroyed crop fields and livestock storage structures, and drained local ponds. Just one year ago, renewed activity at the nearby Los Iros mud volcano triggered a similar coastal uplift at the local beach, pushing some sections of shoreline up as long as 20 feet. That event left key agricultural routes impassable during peak farming season and caused thousands of dollars in lost crop and infrastructure damage for local producers, according to on-the-ground reports from environmental activists and farmers.

  • PUCMM study finds building materials and vegetation drive urban heat in Bayahibe

    PUCMM study finds building materials and vegetation drive urban heat in Bayahibe

    In the Dominican Republic coastal community of Bayahibe, a groundbreaking academic study from the Pontifical Catholic University Madre y Maestra (PUCMM) has uncovered clear causal connections between localized urban temperature fluctuations and three key urban design factors: construction materials, exterior building colors, and the density of green vegetation across the city. This investigation, which focuses on the well-documented Urban Heat Island (UHI) effect – a common environmental phenomenon where developed urban zones register consistently higher temperatures than their undeveloped rural peripheries – was formally unveiled to the global scientific community during the 21st International Congress of Scientific Research, hosted by the Dominican Republic’s Ministry of Higher Education, Science and Technology (MESCyT).

    To reach their evidence-based conclusions, the PUCMM research team conducted on-the-ground temperature and infrastructure surveys across 24 distinct city blocks, collecting granular data from 355 individual buildings to map how different urban features shape local heat levels. Their analysis confirmed that urban districts dominated by heat-absorbent materials including asphalt, concrete, and zinc roofing, paired with sparse tree coverage, recorded the highest peak and average temperatures in the entire study area. By comparison, residential neighborhoods with extensive tree planting and large expanses of permeable, water-absorbent ground surfaces stayed significantly cooler throughout the study period, even during peak midday heat. The team also added nuanced findings about building design: light-colored exterior facades, most notably pure white coatings, reflect far more incoming solar radiation away from building structures, preventing excess heat from building up in urban surfaces and air. Darker facade pigments, by contrast, trap solar energy, driving up both surface and ambient air temperatures across surrounding blocks.

    The study’s authors issued a urgent warning about the growing risks of the UHI effect for small coastal Caribbean cities like Bayahibe, which already face overlapping climate hazards including accelerating sea level rise, increasing ocean warming, and more frequent, more intense extreme heat events driven by global climate change. To mitigate these rising risks, the research team put forward a set of actionable, accessible policy and design recommendations: expanding the total area of urban green space and street tree planting city-wide, switching to high-reflectance construction materials for new development and retrofits, and investing in shaded public gathering spaces to protect vulnerable communities from extreme heat. These changes, the authors note, would not only improve public thermal comfort and reduce heat-related health risks but also cut overall city energy consumption for air conditioning, creating secondary environmental and economic benefits for local residents.
