eznews.inIn a surprising revelation for British readers, many Americans have never tasted blackcurrant, a popular berry in the UK known for its rich flavor and high vitamin C content. While blackcurrants (_Ribes nigrum_) are a staple in British cuisine, featuring in products like jams and drinks, their absence in the US stems from a historical ban initiated in the early 1900s. This prohibition was a response to the white pine blister rust fungus, which threatened the timber industry. Although the ban was lifted in some states, including New York in 2003, blackcurrants remain largely unknown to most Americans, with estimates suggesting less than 0.1% have ever tried them. Efforts by advocates like Greg Quinn are slowly introducing blackcurrant products to the US market, but confusion persists, as many still associate the "purple" flavor with grape instead of blackcurrant, highlighting a significant cultural divide. 
Published: Dec 01 2025, 10 pmeznews.inA recent study in Thailand has revealed the existence of a rare blood type, designated B(A), found in only three individuals out of over half a million samples analyzed. Researchers conducted a retrospective review of 285,450 donor and 258,780 patient samples, identifying fewer than 400 ABO discrepancies, with the new blood type emerging unexpectedly. The B(A) phenotype exhibited a small amount of A antigen activity, a unique genetic variant not previously documented in the Thai population. While this discovery may pose challenges for future blood transfusions, it primarily highlights the complexities of blood typing, a field that has evolved significantly since Karl Landsteiner established the ABO system over a century ago. The findings underscore the need for further research into ABO discrepancies and the genetic mutations that contribute to rare blood types, as detailed in the journal *Transfusion and Apheresis Science*.
Published: Dec 01 2025, 7 pmeznews.inA recent study has delved into the evolutionary journey of species that transitioned from land back to aquatic environments, examining hundreds of museum specimens at the Yale Peabody Museum and other institutions. Researchers conducted over 11,000 measurements and utilized a statistical model to assess fossil features indicative of either aquatic or terrestrial lifestyles. Lead author Caleb Gordon noted the challenges posed by ambiguous limb structures in some species, complicating their classification. The study revealed that hand length measurements were particularly effective in predicting aquatic adaptations, achieving around 90% accuracy. Notably, the findings suggest that _Spinosaurus_ spent significant time submerged, supporting theories of its underwater hunting capabilities. The research, published in *Current Biology*, offers a framework that could enhance understanding of evolutionary history across various species.
Published: Dec 01 2025, 8 pmeznews.inDomestic cats, beloved companions worldwide, can trace their lineage back to North African wildcats from around 2,000 years ago, according to new research. Previously, it was believed that cats were domesticated during the Neolithic period in the Levant, supported by archaeological findings of ancient cat burials. However, a study analyzing the genomes of 70 ancient cats revealed that specimens older than 2,000 years were actually European wildcats, not domestic cats. Researchers, including Marco de Martino, emphasized that while early humans may have coexisted with wildcats, true domestication occurred much later. The first domestic cats, descended from North African wildcats, spread rapidly throughout the Roman Empire, reaching the British Isles by the first century BCE. This research shifts the timeline of cat domestication from thousands of years ago to a more recent period, highlighting a significant change in our understanding of feline history. The findings are published in the journal Science.
Published: Nov 28 2025, 1 ameznews.inThe European Space Agency's Mars Express and ExoMars Trace Gas Orbiter have expanded their capabilities beyond their primary missions, recently capturing data on interstellar comet 3I/ATLAS and measuring Martian surface winds. Utilizing a comprehensive catalog of 1,039 dust devils—tornado-like phenomena observed by various rovers and orbiters—the spacecraft revealed that wind speeds can reach up to 160 kilometers (100 miles) per hour, significantly faster than previously estimated. Lead author Valentin Bickel noted that dust devils make the invisible winds visible, allowing for a global mapping of wind patterns on Mars, a feat previously unattainable due to limited data. This new understanding is crucial for future exploration missions, particularly those relying on solar power, as dust storms can obscure sunlight and jeopardize equipment. The findings were published in *Science Advances*, highlighting the importance of understanding Martian atmospheric dynamics.
Published: Dec 01 2025, 2 pmeznews.inA study from the Duke Canine Cognition Center has revealed that a dog's ability to cope with stress and perform tasks is closely linked to its temperament. Researchers tested two groups of dogs—pet dogs and service dogs—by measuring their reactions to stress-inducing situations. The experiment involved retrieving a treat while being encouraged in either a calm or excited manner. While the service dogs thrived under enthusiastic encouragement, the more excitable pet dogs struggled, with one spaniel breaking down under pressure. This aligns with the Yerkes-Dodson law, which suggests that moderate stress can enhance performance, but excessive stress can hinder it. The findings aim to assist trainers in selecting service dogs that can better handle high-stress environments, highlighting the importance of temperament in canine performance.

This new image boasts double the resolution and size of the previous GLEAM map from 2019, with ten times the sensitivity, offering unprecedented insights into the galaxy's structure and stellar evolution. Mantovanini's research highlights supernova remnants and stellar nurseries, with the vibrant image revealing exploded stars as large red circles and active star-forming regions as smaller blue areas. The groundbreaking map is expected to facilitate numerous discoveries, with the SKA Observatory's upcoming SKA-Low telescope anticipated to surpass it in sensitivity and resolution within the next decade. The findings are detailed in the Publications of the Astronomical Society of Australia.
Published: Dec 01 2025, 11 ameznews.inThe East Antarctic Plateau holds the title of the coldest place on Earth, with temperatures at Russia's Vostok Station plummeting to -89.2°C (-128.6°F) on July 23, 1983. Recent satellite data from the National Snow and Ice Data Center, covering 2004 to 2016, revealed even lower temperatures of around -98°C (-144.4°F) in the region during the polar night, particularly at altitudes of 3,800 to 4,050 meters (12,467 to 13,287 feet). These extreme conditions are exacerbated by a strong Antarctic polar vortex, which traps cold air. While these temperatures are naturally occurring, scientists have achieved even colder conditions in laboratory settings, nearing absolute zero. In 2021, German researchers set a record by cooling rubidium atoms to 38 picokelvins, creating a Bose-Einstein condensate, where atoms behave as a single quantum entity, showcasing the bizarre phenomena of quantum physics.
Published: Nov 27 2025, 11 pmeznews.inA recently discovered ancient Babylonian clay tablet, dating back to 1770 BCE, reveals that the Pythagorean theorem predates the Greek philosopher Pythagoras by over a millennium. The tablet, known as IM 67118, demonstrates the use of the theorem to calculate the diagonal of a rectangle, indicating that Babylonian mathematicians were aware of this mathematical principle long before Pythagoras was born around 570 BCE. Another tablet from 1800-1600 BCE also shows knowledge of the theorem through labeled triangles. Mathematician Bruce Ratner notes that the Babylonians understood the relationship between a square's diagonal and its sides, suggesting familiarity with the theorem's special case. The attribution of the theorem to Pythagoras likely stems from the secretive nature of his school, which passed knowledge orally, leading to many discoveries being credited to him. Despite not originating the theorem, Pythagoras's school played a crucial role in its popularization.
