Published Direct evidence found for dairy consumption in the Pyrenees in the earliest stages of the Neolithic
(via sciencedaily.com) Original source A study on the remains of the Chaves and Puyascada caves, both located in the province of Huesca, Spain, yields the first direct proof of the consumption and processing of dairy products in the Pyrenees already at the start of the Neolithic period, approximately 7,500 years ago, as well as the consumption of pig. The results lead to doubts about the belief that these products were first used much later in the Pyrenean mountain range.
Published Ancient polar sea reptile fossil is oldest ever found in Southern Hemisphere
(via sciencedaily.com) Original source An international team of scientists has identified the oldest fossil of a sea-going reptile from the Southern Hemisphere -- a nothosaur vertebra found on New Zealand's South Island. 246 million years ago, at the beginning of the Age of Dinosaurs, New Zealand was located on the southern polar coast of a vast super-ocean called Panthalassa. 'The nothosaur found in New Zealand is over 40 million years older than the previously oldest known sauropterygian fossils from the Southern Hemisphere.
Published Quantum entanglement measures Earth rotation
(via sciencedaily.com) Original source Researchers carried out a pioneering experiment where they measured the effect of the rotation of Earth on quantum entangled photons. The work represents a significant achievement that pushes the boundaries of rotation sensitivity in entanglement-based sensors, potentially setting the stage for further exploration at the intersection between quantum mechanics and general relativity.
Published New research finds biases encoded in language across cultures and history
(via sciencedaily.com) Original source Researchers share evidence that people's attitudes are deeply woven into language and culture across the globe and centuries.
Published Quantum data assimilation: A quantum leap in weather prediction
(via sciencedaily.com) Original source Data assimilation is an important mathematical discipline in earth sciences, particularly in numerical weather prediction (NWP). However, conventional data assimilation methods require significant computational resources. To address this, researchers developed a novel method to solve data assimilation on quantum computers, significantly reducing the computation time. The findings of the study have the potential to advance NWP systems and will inspire practical applications of quantum computers for advancing data assimilation.
Published Ancient Syrian diets resembled the modern 'Mediterranean diet'
(via sciencedaily.com) Original source Thousands of years ago, people in ancient Syria likely ate mostly grains, grapes, olives and a small amount of dairy and meat -- similar to today's 'Mediterranean diet,' according to a new study.
Published Quantum dots and metasurfaces: Deep connections in the nano world
(via sciencedaily.com) Original source A team has developed printable, highly efficient light-emitting metasurfaces.
Published Origin and spread of malaria
(via sciencedaily.com) Original source Researchers have reconstructed the evolutionary history and global spread of malaria over the past 5,500 years, identifying trade, warfare, and colonialism as major catalysts for its dispersal.
Published Ritual sacrifice at Chichén Itzá
(via sciencedaily.com) Original source Rising to power in the wake of the Classic Maya collapse, Chichen Itz was among the largest and most influential cities of the ancient Maya, but much about its political connections and ritual life remain poorly understood. Close kin relationships, including two pairs of identical twins, suggests a connection to the Maya origin myths of the Popol Vuh.
Published Scientists unlock secrets of how archaea, the third domain of life, makes energy
(via sciencedaily.com) Original source An international scientific team has redefined our understanding of archaea, a microbial ancestor to humans from two billion years ago, by showing how they use hydrogen gas. The findings explain how these tiny lifeforms make energy by consuming and producing hydrogen. This simple but dependable strategy has allowed them to thrive in some of Earth's most hostile environments for billions of years.
Published New technique could help build quantum computers of the future
(via sciencedaily.com) Original source Researchers have demonstrated a new method that could enable the large-scale manufacturing of optical qubits. The advance could bring us closer to a scalable quantum computer.
Published Shedding light on the origin of a genetic variant underlying fungal infections
(via sciencedaily.com) Original source Variants in the CARD9 gene increase susceptibility to severe fungal infections. However, individuals in different parts of the world tend to carry specific CARD9 variants, making it complex to track the origin of these mutations. In a recent study, a research team conducted genetic analyses on Japanese, Korean, and Chinese patients, revealing that they all shared a variant of CARD9 stemming from a common ancestor from less than 4,000 years ago.
Published Switching nanomagnets using infrared lasers
(via sciencedaily.com) Original source Physicists have calculated how suitable molecules can be stimulated by infrared light pulses to form tiny magnetic fields. If this is also successful in experiments, the principle could be used in quantum computer circuits.
Published Tiny new species of great ape lived in Germany 11 million years ago
(via sciencedaily.com) Original source Ancient apes in Germany co-existed by partitioning resources in their environment, according to a new study.
Published The unexpected origins of a modern finance tool
(via sciencedaily.com) Original source Surprisingly, the origins of financial discounting began with 17th-century English clergymen.
Published 'Missing' early sea sponges discovered
(via sciencedaily.com) Original source Geobiologists reported a 550 million-year-old sea sponge that had been missing from the fossil record. The discovery sheds new light on a conundrum that has stumped zoologists and paleontologists for years.
Published Groundbreaking progress in quantum physics: How quantum field theories decay and fission
(via sciencedaily.com) Original source An international research team has sparked interest in the scientific community with results in quantum physics. In their current study, the researchers reinterpret the Higgs mechanism, which gives elementary particles mass and triggers phase transitions, using the concept of 'magnetic quivers.'
Published Crucial shift in River Nile's evolution during ancient Egypt discovered
(via sciencedaily.com) Original source Researchers have explored how the River Nile evolved over the past 11,500 years and how changes in its geography could have helped shape the fortunes of ancient Egyptian civilization. Research reveals a major shift in the Nile around four thousand years ago, after which the floodplain in the Nile Valley around Luxor greatly expanded.
Published Kinship and ancestry of the Celts in Baden-Württemberg, Germany
(via sciencedaily.com) Original source The Celtic culture of the pre-Roman Iron Age in Western and Central Europe has left numerous traces to this day, not least in the form of enormous burial mounds and spectacular archaeological artifacts. Despite this rich legacy, much about this civilization remains hidden from us.
Published The coldest lab in New York has new quantum offering
(via sciencedaily.com) Original source Physicists describe the successful creation of a molecular Bose-Einstein condensate (BEC). Made up of dipolar sodium-cesium molecules that were cooled with the help of microwave shielding to just 5 nanoKelvin and lasted for up to two seconds, the new molecular BEC will help scientists explore a number of different quantum phenomena, including new types of superfluidity, and enable the creation of quantum simulators to ecreate the enigmatic properties of complex materials, like solid crystals.
