  • Dominica’s night sky set for a spectacular partial lunar eclipse on Friday

    Dominica’s night sky set for a spectacular partial lunar eclipse on Friday

    Stargazing enthusiasts across the Caribbean island of Dominica are gearing up for one of the most anticipated celestial events of 2026, a near-total partial lunar eclipse that will bring a striking Blood Moon display to local skies — provided weather conditions stay clear for the overnight show.

    While astronomers classify the event as a partial lunar eclipse, it will come remarkably close to a full total eclipse when viewed from Dominica. At the peak of the spectacle, roughly 93.9% of the Moon’s full disk will be covered by Earth’s darkest, central shadow, the umbra, creating a visual almost indistinguishable from a total eclipse for casual observers.

    The event will unfold in stages across the night of Thursday, August 27 and into the early hours of Friday, August 28. The first subtle phase, known as the penumbral eclipse, kicks off at 9:23 PM local time on August 27, when the Moon begins sliding into Earth’s faint outer shadow. This initial phase is often hard to spot with the naked eye, but the show becomes unmistakable starting at 10:33 PM, when the Moon first touches the darker umbra. From that point onward, observers can watch as Earth’s curved shadow slowly creeps across the lunar surface.

    The highlight of the night, maximum eclipse, arrives at exactly 12:12 AM on August 28. This is when the coverage of the Moon hits its 93.9% peak, and the full effect of the rare coloring becomes visible. The eclipsed portion of the Moon will take on a deep, dramatic reddish, copper, or crimson hue — a phenomenon popularly called a Blood Moon.

    This iconic red coloring is not a random coincidence: according to NASA, it forms as sunlight passes through Earth’s atmosphere before reaching the lunar surface. Shorter blue wavelengths of light scatter out as they move through the atmosphere, while longer red and orange wavelengths bend through the air and are redirected onto the eclipsed Moon, creating the characteristic Blood Moon glow.

    After the maximum peak, the shadow begins to retreat. The partial eclipse phase concludes at 1:51 AM, with the Moon leaving the umbra, and the final faint penumbral phase wraps up entirely by 3:01 AM.

    Unlike the dangerous solar eclipses that require special protective gear to view safely, this lunar event is completely accessible to all skywatchers. No specialized optical equipment is needed to enjoy the main display; the eclipse is perfectly safe to view with the naked eye, meaning anyone can step outside at the right time and look toward the Moon to see the spectacle. Those with binoculars or a small telescope will be able to make out finer details of the shadow’s edge and the gradient of colors across the Moon’s face, but even unassisted viewing will deliver a stunning show for those lucky enough to have clear skies.

    Local astronomy groups and skywatching enthusiasts are already encouraging residents and visitors to mark their calendars for the event, noting that near-total partial eclipses of this magnitude are relatively rare occurrences for any given location.

  • China stelt lancering Chang’e-7-maanmissie uit, jacht op waterijs op pauze

    China stelt lancering Chang’e-7-maanmissie uit, jacht op waterijs op pauze

    China has announced a last-minute delay to its highly anticipated Chang’e-7 lunar mission, a groundbreaking unmanned expedition targeted at the moon’s south pole that aimed to detect and study buried water ice deposits. The mission, originally scheduled for launch within the next few days from the Wenchang Space Launch Center on China’s southern island province of Hainan, was called off after Chinese space authorities determined the probe failed to meet pre-launch technical requirements.

    In a brief statement released Sunday, the China National Space Administration confirmed that the mission will not proceed within its originally planned launch window this year. The decision followed a comprehensive technical evaluation conducted under the core guiding principles of caution, reliability, and a commitment to ensuring absolute mission success. No further details have been provided on the specific issues that prompted the delay, and no revised launch date has been announced to date.

    As the seventh mission in China’s expanding Chang’e lunar exploration program, Chang’e-7 is widely regarded as the most technologically sophisticated unmanned lunar mission the country has ever developed. The multi-component mission consists of four separate craft: an orbiter that will circle the moon, a main lander, a wheeled rover, and an innovative small flying robot capable of crawling, jumping, and hovering across challenging lunar terrain. Its primary objective is to touch down in the permanently shadowed craters that dot the moon’s south pole, a remote region where planetary scientists suspect large, viable deposits of water ice have been preserved over billions of years.

    The discovery and characterization of lunar water ice carries enormous strategic and scientific value for future human deep space exploration. These deposits could be processed to produce drinking water, breathable oxygen, and even rocket propellant — resources that are critical to establishing a long-term permanent human outpost on the moon. This potential has turned the lunar south pole into the epicenter of a new global space race, led primarily by China and the United States. While the U.S. has deployed multiple probes targeting the region, no mission to date has successfully completed core sampling and verification of accessible water ice deposits.

    Prior to the delay announcement, experts noted that Chang’e-7 was positioned to become the first mission to achieve this historic milestone, and the postponement could temporarily shift the dynamics of the ongoing global lunar competition. “With Chang’e-7, China’s lunar program is shifting from pure exploration to a focus on resource utilization,” Yuqi Qian, a lunar geologist at the University of Hong Kong, previously told CNN. The mission was expected to deliver definitive answers on whether the lunar south pole holds enough usable water ice to support future human activities, marking a key step forward in global lunar research.

    China’s lunar program takes its name from Chang’e, the traditional Chinese moon goddess. The program’s most recent prior mission, Chang’e-6, made global history in 2024 as the first probe ever to return rock and soil samples from the far side of the moon, a feat that demonstrated China’s growing advanced deep space exploration capabilities. As of now, the timeline for Chang’e-7’s new launch date remains unclear.

  • Onderzoek: Visafval kan grondstof worden voor visolie en kippenvoer

    Onderzoek: Visafval kan grondstof worden voor visolie en kippenvoer

    Across Suriname’s thriving fishing industry, large volumes of fish byproducts — including heads, fins, bones, scales, offal, and unwanted bycatch — have long been treated as valueless waste, discarded in landfills or dumped at sea. This widespread practice not only squanders potentially useful organic material packed with proteins, fats, and minerals but also creates unnecessary environmental pressure. Now, a new undergraduate study from Anton de Kom University of Suriname (AdeKUS) has uncovered a practical, sustainable path to repurposing this discarded material into high-value products: crude fish oil and nutrient-adequate starter feed for broiler chickens.

    The research was completed by Mukhlis Karsodjojo, who earned his Bachelor of Science in Agricultural Production with a specialization in Agroprocessing from the university’s Faculty of Technological Sciences on August 17. Karsodjojo’s core research objective was to identify ways to unlock greater economic value from the residual waste streams generated by Suriname’s domestic fishing sector, turning a widespread disposal problem into a usable local resource.

    To test viable approaches for extracting fish oil from fish waste, Karsodjojo evaluated two eco-friendly extraction methods: wet rendering and enzymatic hydrolysis, testing both on waste from a single fish species and mixed-species waste residues. Both methods successfully produced usable crude fish oil, which the study assessed across key metrics including total yield, color, odor, and mineral oil contamination. The analysis found that enzymatic hydrolysis delivered a significantly higher oil output than wet rendering, marking it as the more efficient and effective green extraction method for small-scale local operations.

    In the second phase of the study, Karsodjojo explored integrating processed fish waste into starter feed for young broiler chickens. He developed custom feed formulations that combined processed fish byproducts with locally available Surinamese ingredients, then tested the nutritional content of these blends, measuring moisture, ash, protein, fat, and carbohydrate levels. When compared to mass-produced commercial starter feed currently sold in Suriname, the custom blends met all requirements for adequate nutrient content, proving the concept’s nutritional viability.

    While the research confirms the technical feasibility of this circular economy approach, it also highlights a key remaining barrier to widespread adoption: on small production scales, the cost of manufacturing the custom fish-based starter feed currently exceeds the price of standard commercial alternatives. Despite this economic challenge, the study emphasizes that the approach delivers meaningful systemic benefits: it reduces total waste volumes, cuts reliance on imported feed ingredients by leveraging local raw materials, and creates new economic value from material that would otherwise be discarded entirely.

    Karsodjojo’s work concludes that Suriname has significant untapped potential to utilize fish byproducts more sustainably, but notes that further research is still needed. Future studies should focus on developing effective refining methods for the crude fish oil extracted from waste, and on identifying process adjustments to lower production costs for the chicken starter feed to make it competitive with commercial options. The research was supervised and reviewed by a team of academic advisors including dr. ir. F. van Genderen, dr. A. Kent, ing. S. Moeljoredjo, M. Jaggan, and prof. L. Ori.

  • Government supports INTEC and AI Robotix Alzheimer’s research project

    Government supports INTEC and AI Robotix Alzheimer’s research project

    In a major push for advanced neurodegenerative disease research in the Caribbean, the government of the Dominican Republic has announced its formal backing for an ambitious Alzheimer’s research project led by two domestic institutions: the Technological Institute of Santo Domingo (INTEC) and AI technology firm AI Robotix. Merging expertise across four cutting-edge fields—artificial intelligence, neuroscience, molecular biology, and data science—the initiative aims to unlock groundbreaking new strategies for the early detection, prevention, and therapeutic intervention of Alzheimer’s, a progressive neurodegenerative condition that affects millions of people globally.

    The collaborative project was officially presented to top Dominican government leaders last week during a closed-door meeting held at the National Palace in Santo Domingo. Attendees included President Luis Abinader, Vice President Raquel Peña, and José Ignacio Paliza, Minister of the Presidency. Leading the presentation were Arturo El Villar, rector of INTEC, and Juan Carlos Guilbe, chief executive officer of AI Robotix, who outlined the project’s core objectives and long-term impact potential for both the Dominican Republic and global Alzheimer’s research.

    At the core of the project is the application of sophisticated artificial intelligence models, which are designed to process and analyze massive datasets of existing scientific and biomedical research findings. Unlike traditional research methods that require researchers to manually sort through thousands of studies, the AI system can identify subtle, previously unrecognized patterns across disparate datasets and generate evidence-based new hypotheses. These generated hypotheses will then serve as guiding frameworks for future clinical and basic science research into Alzheimer’s treatments, potentially accelerating the pace of discovery dramatically.

    The initiative has assembled a diverse team of both domestic and international experts to advance its work, bringing together interdisciplinary perspectives that are rarely combined in traditional Alzheimer’s research. Among the leading global specialists joining the team is Ricardo Allegri, a prominent Argentine neurologist and psychiatrist with decades of acclaimed work in neuroscience and Alzheimer’s research. He will collaborate alongside local lead researcher Manuel Colomé, a professor at INTEC, as well as a cohort of specialized experts in artificial intelligence, molecular biology, and data science from institutions across the region and beyond.

    Per statements from INTEC, the project carries far-reaching implications beyond the search for new Alzheimer’s tools and treatments. Institutional leaders noted that the successful execution of the initiative could establish the Dominican Republic as a leading regional hub for high-impact scientific research, technological innovation, and advanced translational health research. Most notably, the project is designed to serve as a global proof of concept, demonstrating how cross-sector collaboration, interdisciplinary expertise, and artificial intelligence can be leveraged to tackle some of the most pressing unmet global health challenges of the 21st century.

  • Can Man’s Best Friend Read Your Mood? Science Says Yes!

    Can Man’s Best Friend Read Your Mood? Science Says Yes!

    For centuries, dog owners have anecdotally claimed their four-legged companions can sense when they are happy, upset, or distressed. Now, a groundbreaking 2026 study from the University of Vienna has turned this common observation into hard scientific evidence, confirming that dogs’ brains process and differentiate between distinct human emotional states in measurable ways.

    Led by researchers Laura Cuaya and Raúl Hernández-Pérez, the investigation used advanced machine learning algorithms to analyze full-brain functional scans of domestic dogs as the animals viewed images of human faces displaying four core emotions: happiness, anger, fear, and sadness. What the team found offers unprecedented insight into the canine social brain: regions of the dogs’ brains tied to higher-order cognitive function and reward processing only activated when the animals were shown images of happy human faces.

    The research also confirmed that dogs can successfully distinguish between different categories of negative human emotion. While negative expressions did not spark activity in the brain’s reward centers, separate, distinct neural activation patterns emerged for fear, anger, and sadness — providing direct neurological proof that dogs do not lump all negative human moods together.

    Cuaya and Hernández-Pérez attribute this ability to thousands of years of domestication. Over generations of coexisting alongside humans, dogs’ brains have undergone evolutionary changes that fine-tuned their social cognitive skills to understand and cooperate with people. For domestic dogs, a human smile is not just a random facial gesture: it acts as a direct, biologically encoded reward, the study concludes.

    To assemble their study cohort, the researchers recruited well-behaved pet dogs from local parks, adding two of their own border collies, named Odín and Kun-kun, to the participant group. The team was transparent about key limitations of their work: the overall sample size remained small, dogs were shown static photographs rather than dynamic, in-person facial expressions, and all participants came from nurturing home environments, meaning results may not apply to dogs with different life backgrounds.

    This research is part of a broader, ongoing program of study focused on how canines interpret human communication and behavior. Moving forward, the research team plans to expand their work to explore how dogs integrate multiple signals — facial expressions, body language, vocal intonation, and even human scent — to build a complete understanding of the people around them.

  • Hundreds of Shooting Stars to Be Visible From Antigua and Barbuda Tonight

    Hundreds of Shooting Stars to Be Visible From Antigua and Barbuda Tonight

    Stargazers across Antigua and Barbuda are preparing for a rare chance to witness one of the most spectacular annual celestial events, as the Perseid meteor shower reaches its peak activity overnight between Wednesday and early Thursday.

    Astronomy experts have outlined a clear window for optimal viewing, noting that the best opportunity to spot shooting stars will fall between 2 a.m. and dawn on Thursday, with the highest frequency of meteors projected to occur between 3 a.m. and 5 a.m. This prime window is only accessible if atmospheric conditions stay clear of heavy cloud cover, forecasters add.

    For new and experienced observers alike, simple preparation can drastically improve the viewing experience. Aspiring sky-watchers are advised to seek out a remote, dark spot far from the glow of urban streetlights and artificial light pollution. While viewers should initially orient themselves toward the northeastern sky to align with the shower’s radiant point, Perseid meteors can appear in any part of the overhead sky, so experts recommend keeping a broad, open gaze rather than focusing on a single small area.

    Unlike many deep-space celestial events, the Perseid meteor shower requires no specialized optical equipment such as binoculars or telescopes to enjoy. In fact, using such gear can narrow the field of view and reduce the chance of catching meteors. Observers are also reminded to put away mobile phones and other glowing screens at least 20 minutes before beginning their viewing session, as this gives human eyes time to fully adjust to low-light conditions and become sensitive to the faint streaks of fast-moving meteors.

    This year’s shower comes with an unusual advantage for sky-watchers: the peak of Perseid activity aligns perfectly with a new moon. A new moon produces virtually no moonlight, eliminating the single largest source of natural light interference that often obscures fainter meteors in other years. This alignment creates what experts call near-ideal conditions for viewing across Antigua and Barbuda.

    The Perseid meteor shower is a recurring annual event, triggered when Earth’s orbit carries it through the trail of icy debris and dust left behind by the periodic comet 109P/Swift-Tuttle. As small particles from the comet’s trail enter Earth’s upper atmosphere at speeds of more than 130,000 miles per hour, they vaporize due to friction, creating the bright, glowing streaks that people know as shooting stars.

    Under perfectly dark, clear sky conditions, astronomers estimate that up to 100 meteors per hour can be spotted during the Perseid peak. However, the actual number visible to observers in Antigua and Barbuda this year will still depend on local factors including cloud cover, the level of nearby light pollution, and how far a viewing site is from urban development.

  • LIVE: Solar Eclipse 2026

    LIVE: Solar Eclipse 2026

    On August 12, 2026, a highly anticipated total solar eclipse will cross the Northern Hemisphere, drawing the attention of astronomers, skywatchers, and curious observers across the globe. This rare astronomical event will see the moon pass directly between the Earth and the sun, completely blocking the sun’s bright disk and casting a narrow path of totality across several Arctic and North Atlantic regions.

    The zone where the total eclipse will be fully visible stretches across a chain of high-latitude and European locations. Among the areas that will experience the full glory of a total solar eclipse are the massive ice sheet of Greenland, the entire island nation of Iceland, and the northernmost territories of Russia. In Western Europe, the path of totality will cut across northern regions of Spain, with the extreme northeastern tip of Portugal also falling within the zone of full eclipse. Large stretches of the Atlantic Ocean between North America and Europe also lie along the path of totality, giving any ships sailing in those areas a front-row seat to the event.

    For observers not located along the narrow path of totality, the event will still offer a striking partial solar eclipse, where the moon covers only a portion of the sun’s surface. Much of North America will get the chance to see at least a partial eclipse, including all of northern Canada and a large swathe of the United States stretching from Alaska in the far northwest all the way to North Carolina on the U.S. East Coast. Beyond North America, most of the European continent will also witness a noticeable partial eclipse, alongside northwestern regions of Africa. Even for those unable to view the partial eclipse, the event will be widely broadcast via live streams from astronomy organizations, giving people around the world a chance to experience the rare astronomical phenomenon.

    Total solar eclipses are infrequent events for any given location on Earth, occurring roughly once every 375 years in the same spot. This makes the 2026 eclipse a particularly exciting opportunity for the communities and skywatchers in its path of totality, with tourism officials in Iceland and northern Spain already preparing for an influx of visitors eager to view the event.

  • Dominican Republic establishes National Physicist Day to promote science

    Dominican Republic establishes National Physicist Day to promote science

    Santo Domingo, Dominican Republic — The Dominican Academy of Sciences (ACRD) has formally launched a new annual national observance, National Physicist Day, which will be celebrated every June 3 starting under the authority of Presidential Decree No. 454-26, officially issued on July 6, 2026. The launch ceremony took place at the ACRD’s central headquarters, drawing a diverse cross-section of attendees including leading academics, veteran researchers, physics educators, university students, and practicing physics professionals from across the country. Throughout the event, participants emphasized the irreplaceable role that the field of physics plays in driving the Dominican Republic’s scientific advancement, technological innovation, and long-term social progress. Melvin Arias, who coordinates the ACRD’s Commission of Basic Sciences and Technology, outlined the core goals behind the new annual celebration. Arias explained that the recurring observance will serve as a key platform to expand public science engagement, reinforce the quality of physics instruction across secondary and post-secondary institutions, and motivate young Dominican students to pursue careers in scientific research and applied physics. A central formal element of the ceremony featured the official reading of the presidential decree by Editrudis Beltrán Crisóstomo, a longtime professor at the Autonomous University of Santo Domingo (UASD) School of Physics and a former university rector. Following the reading, attendees held a moment of quiet respect, observing a minute of silence to honor the legacy of Dominican physicists who have passed away. Closing out the formal proceedings, the Dominican Society of Physics (SoDoFi) presented special recognitions to both Beltrán Crisóstomo and Emma Encarnación, honoring their decades of impactful contributions to the growth and development of the physics discipline across the Dominican Republic. The push to establish National Physicist Day received formal institutional support from multiple key national stakeholders, including SoDoFi, the Dominican Ministry of Higher Education, Science and Technology (Mescyt), the Autonomous University of Santo Domingo, and the Academy of Sciences itself. Event organizers emphasized in closing statements that the creation of this dedicated national day reinforces the Dominican Republic’s ongoing commitment to expanding scientific research, investing in academic advancement, and building a skilled pipeline of STEM professionals for the nation’s future.

  • Will the solar eclipse be visible in the Dominican Republic? Here’s what to know

    Will the solar eclipse be visible in the Dominican Republic? Here’s what to know

    One of 2024’s most anticipated astronomical events is just around the corner: a total solar eclipse set to occur this Wednesday, August 12, that is expected to draw millions of observers across the Northern Hemisphere. The rare celestial phenomenon happens when the Moon aligns perfectly between Earth and the Sun, completely obscuring the solar disk for viewers along its narrow path of totality.

    The eclipse’s journey will kick off over the Bering Sea before tracking east across the Northern Hemisphere. The path of totality, where the entire Sun is blocked by the Moon, will cut across portions of the Arctic Ocean, northwest Greenland, Iceland, northern Russia, the Atlantic Ocean, and much of Spain before ending in a small section of Portugal. For residents across a far broader swath of the globe—including large parts of North America, Europe, and northwest Africa—a partial eclipse, where the Moon only covers a fraction of the Sun, will still be visible to the naked eye with proper protection.

    Among all locations along the path, Spain stands out as one of the premier spots to view the total eclipse. Roughly 40% of the country’s total land area falls within the path of totality, including 23 of its provincial capitals, as the eclipse moves from the country’s western edge to its eastern border.

    The peak of the eclipse, when the Moon covers the maximum portion of the Sun and totality is longest, is scheduled to take place near Iceland at 5:46 p.m. GMT. At this location, the total phase of the eclipse will last approximately 2 minutes and 18 seconds.

    As hundreds of thousands of skywatchers are expected to converge on popular viewing spots along the path of totality, public safety officials have issued a series of critical warnings to prevent incidents. The most urgent reminder centers on eye protection: all people looking directly at the eclipse, even during the partial phase, must use certified solar viewing glasses that meet the international ISO 12312-2 safety standard. Unprotected viewing can cause permanent, irreversible damage to the retina of the eye. Beyond eye safety, authorities have also warned attendees to prepare for risks including extreme heat, dehydration, overcrowding at viewing sites, congestion of cellular communication networks, elevated risk of forest fires in dry viewing areas, and accidental environmental damage from large crowds.

    Beyond being a breathtaking visual spectacle, this solar eclipse also presents a one-of-a-kind research opportunity for astronomers and space scientists. The event will allow experts to study solar physics, patterns of space weather, and complex interactions between solar activity and Earth’s systems, turning the Iberian Peninsula into an improvised, open-air natural laboratory for the duration of the event.

    For people unable to travel to the path of totality or those who live in regions where only a partial eclipse is visible, the U.S. National Aeronautics and Space Administration (NASA) will host a free, public live broadcast of the entire event. NASA’s coverage will begin at 1:15 p.m. EDT, and will feature high-resolution images from multiple observation points along the eclipse’s path, professional telescope footage of the solar corona, and live commentary from leading astronomical experts.

    Residents of the Dominican Republic, for example, lie entirely outside the eclipse’s path of totality, meaning a total eclipse will not be visible from the island nation. Even so, local astronomy enthusiasts can still experience the event in real time through NASA’s official online livestream.

  • 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.
