A recent observation by zoologist Vladimir Dinets highlights the remarkable adaptability and intelligence of Cooper's hawks in urban environments. While many animals have learned to exploit human infrastructure, Dinets noted a specific hawk that skillfully used traffic signals to enhance its hunting strategy. At a New Jersey intersection, the hawk would wait for a pedestrian to press a button, triggering a longer red light that created a queue of cars, providing cover for its approach to a nearby house where smaller birds gathered for crumbs. This behavior demonstrates the hawk's understanding of cause and effect, as well as its ability to navigate complex urban landscapes. Dinets emphasized that this immature hawk, likely new to the city, had already mastered the art of using traffic patterns to its advantage, showcasing the intelligence of birds often underestimated in their ability to thrive in human-dominated habitats. The findings are detailed in Dinets' study published in *Frontiers in Ethology*. 
Published: May 23 2025, 10 pmeznews.inThe tooth-billed pigeon, or manumea, is a critically endangered species in Samoa, often referred to as the "little dodo" due to its rarity and close relation to the extinct bird. Last photographed in 2013, its population has plummeted to fewer than 100 individuals, primarily due to habitat loss, hunting, and predation by invasive species. In a bid to locate these elusive birds, scientists from The Colossal Foundation and the Samoa Conservation Society have developed advanced bioacoustic technology capable of detecting their unique calls with 95% accuracy. This innovative approach utilizes machine learning algorithms to classify bird calls, even for species with minimal recordings. The collaboration aims to locate the pigeons, capture live specimens for biobanking, and potentially establish a captive breeding program to prevent extinction. The initiative represents a significant step in conservation efforts for this national treasure, with hopes of reviving its dwindling population.
Published: May 31 2025, 2 pmeznews.inThe Oldowan stones, dating back 2-3 million years, are the earliest known examples of stone tools, marking a pivotal moment in human evolution by showcasing the first evidence of cultural behavior. Discovered initially at Olduvai Gorge in Tanzania, these tools are characterized by hand-held cores with sharp edges, suitable for cutting and scraping. Despite extensive research, the identity of their creators remains elusive, with various hominin species, including _Homo habilis_ and _Paranthropus boisei_, being considered potential manufacturers. Recent studies suggest that the Oldowan technology may have emerged around 3.25 million years ago and persisted until 1.2 million years ago, indicating a complex interplay of multiple hominin species in tool-making. The research highlights that no single species is solely responsible for the Oldowan tools, suggesting a possible cultural exchange between early _Homo_ and _P. boisei_. The findings are detailed in the Journal of Anthropological Archaeology.
Published: May 31 2025, 6 pmeznews.inWater fluoridation is a contentious issue in the United States, with recent discussions around potential bans gaining momentum. Introduced in Michigan in 1945, fluoride in public drinking water has been credited with improving oral health but has faced significant opposition due to concerns over its neurotoxic effects. U.S. Health Secretary Robert F. Kennedy Jr. has suggested rescinding CDC recommendations for fluoridation, while the EPA is reviewing its health risks. A study by Harvard researchers predicts that halting fluoridation could lead to a 7.5% increase in dental caries over five years, resulting in 25.4 million additional cases and an economic burden of $9.8 billion. The researchers emphasize that, despite fears of toxicity, the benefits of fluoridation at safe levels far outweigh the risks, particularly for children, underscoring the importance of maintaining this public health measure. The findings are published in JAMA Health Forum.
Published: Jun 01 2025, 3 ameznews.inA newly discovered Neanderthal fingerprint, found on a pebble at the San Lázaro rock shelter in central Spain, may have been left by a prehistoric artist painting a face using red ocher. Dated to around 43,000 years ago, the pebble is associated with Neanderthal tools and suggests advanced cognitive abilities, including the capacity for abstraction and pareidolia—the tendency to see faces in inanimate objects. Researchers note that the ocher dot appears deliberately applied, indicating symbolic rather than utilitarian use. The pebble's features, combined with natural depressions, could resemble a human face, leading to speculation about the intentions of its creator. While the study does not definitively conclude the nature of the red dot, it raises the possibility that both Neanderthals and early modern humans shared similar interpretative skills. The findings are detailed in the journal *Archaeological and Anthropological Sciences*.
Published: May 31 2025, 4 pmeznews.inSir David Attenborough's latest documentary, _OCEAN_, features groundbreaking footage from the perspective of a bottom trawler, revealing the devastating impact of this fishing method on marine ecosystems. The film captures fish, cephalopods, and rays fleeing as the trawler's net devastates the seabed, a sight that has deeply affected marine conservationists like Enric Sala, who highlights that bottom trawling produces carbon emissions comparable to global aviation. Research indicates that this practice can strip up to 41% of seabed fauna, with recovery taking over six years. Toby Nowlan, the film's director, compares the destruction to bulldozing ancient woodlands, emphasizing the urgent need for change. As _OCEAN_ airs ahead of the 2025 UN Ocean Conference, it aims to raise awareness and prompt action to protect 30% of the ocean by 2030, challenging viewers to confront the hidden devastation beneath the waves.
Published: May 29 2025, 5 pmeznews.inFor the first time, researchers have captured a photograph of a living Upemba lechwe (_Kobus anselli_), a critically endangered antelope species, during an aerial survey of the Kamalondo Depression in the Democratic Republic of the Congo, its sole habitat. Lead author Manuel Weber from Upemba National Park described the fleeting moment when he managed to photograph the animal, marking the first published image of the species since its identification in 2005. The recent survey, the first in over 50 years, revealed a stark decline in numbers, estimating fewer than 100 individuals remain, a significant drop from earlier estimates of 5,000 to 20,000 in the 1970s. Poaching has been a major factor in this decline. Weber and his team are calling for immediate protective measures to prevent the species from vanishing entirely, hoping the photograph will galvanize conservation efforts. The findings are published in the African Journal of Ecology.
Published: May 29 2025, 4 pmeznews.inIstanbul-based illustrator and paleoartist C. M. Kosemen has created a striking series of illustrations that re-imagine contemporary animals as if they were depicted solely from their skeletal remains, much like how dinosaurs are often portrayed. These artworks reveal a terrifying and often inaccurate vision of familiar creatures, such as elephants and baboons, which appear alarmingly skeletal due to the guesswork involved in estimating their soft tissue. Kosemen's work highlights the challenges of paleoart, where the absence of living references can lead to distorted representations, as seen in the historical misinterpretation of the woolly rhinoceros as a unicorn in the 17th century. This exploration raises questions about the reliability of fossilized bones as a foundation for understanding extinct species and underscores the evolving nature of scientific reconstructions, as exemplified by the changing depictions of velociraptors over the years.

Published: May 31 2025, 11 pmeznews.inFour critically endangered female eastern lowland gorillas—Mapendo, Ndjingala, Isangi, and Lulingu—have been successfully reintroduced to their natural habitat in Virunga National Park, eastern Democratic Republic of the Congo. Rescued from poachers and rehabilitated at the Gorilla Rehabilitation and Conservation Education Center (GRACE), the gorillas were airlifted to Mt. Tshiaberimu, a site steeped in local lore. This rewilding initiative, supported by over 400 contributors, aims to bolster the region's dwindling gorilla population, which has fallen to just eight individuals. Following their release, the gorillas quickly adapted, interacting with a wild silverback named Mwasa and foraging for new food sources. While the initial signs of success are promising, conservationists acknowledge the ongoing challenges ahead. Experts emphasize the importance of community involvement in conservation efforts, highlighting this project as a potential model for future rewilding initiatives.

Published: May 31 2025, 10 pmeznews.inCrows exhibit a unique response to death, often gathering around deceased members of their species in what can be described as a form of "funeral." This behavior, part of a scientific field known as corvid thanatology, serves a practical purpose: crows investigate the circumstances of the death to assess potential threats. When a crow discovers a dead companion, it emits alarm calls to alert others, leading to a gathering where they scold the carcass for up to 20 minutes. Research indicates that crows can associate specific human faces with danger, particularly when linked to dead crows, demonstrating their capacity for complex decision-making. Interestingly, while crows are often associated with death in folklore, they actively seek to avoid it, showcasing their intelligence and social behavior. This intricate relationship with death highlights the cognitive abilities of these birds, prompting further exploration into their understanding of mortality.
