In a major step toward wildlife conservation, 70 southern white rhinos have been relocated from South Africa to Akagera National Park in Rwanda. This marks the largest translocation of white rhinos to Rwanda, aimed at establishing a secure breeding population and strengthening conservation efforts. White rhinos have been under increasing threat due to habitat loss ...
With only two non-reproductive females remaining, the northern white rhinoceros (Ceratotherium simum cottoni) is functionally extinct. However, scientists have now mapped its complete genome, offering an important tool for conservation efforts. This breakthrough could pave the way for stem cell-based reproductive technologies, potentially restoring the species. How the Genome Was Mapped Researchers used cutting-edge sequencing ...
Artificial intelligence has played a pivotal role in uncovering a potential trigger for Alzheimer’s disease and identifying a promising treatment. Researchers at the University of California, San Diego have found that an enzyme called phosphoglycerate dehydrogenase (PHGDH) may not only serve as a biomarker for Alzheimer’s but could also be a causal factor in the ...
For the first time, scientists have created a comprehensive evolutionary tree of all known bird species, synthesizing data from nearly 300 studies published between 1990 and 2024. This groundbreaking effort provides a unified framework for understanding bird evolution, taxonomy, and ecological relationships. How Scientists Built the Evolutionary Tree Researchers at the Cornell Lab of Ornithology ...
A unique event in Denmark is blending gastronomy with coastal ecology, transforming food lovers into citizen scientists. The annual Østerjagten (Oyster Hunt) at the Salling Sund Bridge in Limfjorden invites participants to wade into shallow waters, collect oysters, and contribute to marine research—all while enjoying gourmet dishes prepared by top chefs. How the Oyster Hunt ...
A genetic mutation that helps protect against HIV infection has been traced back to a single individual who lived near the Black Sea between 6,700 and 9,000 years ago. This discovery challenges previous assumptions about the mutation’s origins, suggesting it spread rapidly across Eurasia long before the Viking Age. Tracing the Mutation’s Origins Scientists analyzed ...
A groundbreaking study has revealed that North American bird populations are declining most severely in areas where they should be thriving. Researchers analyzed 36 million bird observations submitted by birdwatchers to the Cornell Lab’s eBird program, alongside environmental data from high-resolution satellite imagery. How Scientists Mapped Bird Declines Using zoomable maps, scientists tracked population trends ...
A previously unknown species of ribbon worm, Pararosa vigarae, has been discovered off the northwest coast of Spain. The marine worm, nicknamed the accordion worm, can shrink to one-fifth of its size when alarmed, forming distinct ring-like folds along its body. Scientists believe this unique contraction ability may serve as a defensive mechanism or aid ...
Sharks, rays, and other chondrichthyans have evolved a remarkable range of reproductive strategies, allowing them to thrive for hundreds of millions of years. Two particularly unusual methods—facultative parthenogenesis and multiple embryos per egg case (MEPE)—may provide key survival advantages, though scientists are still investigating their evolutionary benefits. Facultative Parthenogenesis: Reproduction Without Males Facultative parthenogenesis allows ...
California sea lion Ronan has once again stunned scientists with her ability to keep a beat. First recognized in 2013 for her rhythmic precision, Ronan’s latest encore performance proves that her timing rivals—and even surpasses—that of humans. How Ronan Mastered Beat Synchronization Unlike most animals, Ronan can adjust her head-bobbing to different tempos, demonstrating rhythmic ...
