Published Can AI learn like us?



Scientists have developed a new, more energy-efficient way for AI algorithms to process data. His model may become the basis for a new generation of AI that learns like we do. Notably, these findings may also lend support to neuroscience theories surrounding memory's role in learning.
Published The world's oldest wine discovered



A white wine over 2,000 years old, of Andalusian origin, is the oldest wine ever discovered.
Published Simplicity versus adaptability: Understanding the balance between habitual and goal-directed behaviors



Scientists have proposed a new AI method in which systems of habitual and goal-directed behaviors learn to help each other. Through computer simulations that mimicked the exploration of a maze, the method quickly adapts to changing environments and also reproduced the behavior of humans and animals after they had been accustomed to a certain environment for a long time. The study not only paves the way for the development of systems that adapt quickly and reliably in the burgeoning field of AI, but also provides clues to how we make decisions in the fields of neuroscience and psychology.
Published Custom-made molecules designed to be invisible while absorbing near-infrared light



Researchers used theoretical calculations assessing electron orbital symmetry to synthesize new molecule designed to be both transparent and colorless while absorbing near-infrared light. This compound demonstrates the first systematic approach to producing such materials and have applications in advanced electronics. This compound also shows semiconducting properties.
Published Researchers use large language models to help robots navigate



A technique can plan a trajectory for a robot using only language-based inputs. While it can't outperform vision-based approaches, it could be useful in settings that lack visual data to use for training.
Published Quantum data assimilation: A quantum leap in weather prediction



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'



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 Greek Island was home to Bronze Age purple dye workshop



The Greek island of Aegina was home to a Late Bronze Age purple dye workshop, according to a new study.
Published Origin and spread of malaria



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



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 Shedding light on the origin of a genetic variant underlying fungal infections



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 Peers crucial in shaping boys' confidence in math skills



Boys are good at math, girls not so much? A study has analyzed the social mechanisms that contribute to the gender gap in math confidence. While peer comparisons seem to play a crucial role for boys, girls' subjective evaluations are more likely to be based on objective performance.
Published Tiny new species of great ape lived in Germany 11 million years ago



Ancient apes in Germany co-existed by partitioning resources in their environment, according to a new study.
Published Digital babies created to improve infant healthcare



Researchers have created digital babies to better understand infants' health in their critical first 180 days of life. The team created 360 advanced computer models that simulate the unique metabolic processes of each baby.
Published Researchers solve 2,000-year-old mystery of the shipworm



They bedeviled ancient Greek navies, helped shipwreck Christopher Columbus, aided in the sinking of the Spanish Armada and caused the wharves in San Francisco Bay to collapse into the sea, but until now, scientists have been unable to pinpoint exactly how shipworms -- a family of mollusks -- are able to cause such damage. A team of researchers has discovered that a population of symbiotic microbes, living in an overlooked sub-organ of the gut called the 'typhlosole,' have the ability to secrete the enzymes needed to digest lignin -- the toughest part of wood.
Published Blood sausages and yak milk: Bronze Age cuisine of Mongolian nomads unveiled



Bronze cauldrons were used by the inhabitants of the Mongolian steppe around 2,700 years ago to process animal blood and milk. This is shown by a protein analysis of archaeological finds from this period.
Published Using AI to decode dog vocalizations



Have you ever wished you could understand what your dog is trying to say to you? Researchers are exploring the possibilities of AI, developing tools that can identify whether a dog's bark conveys playfulness or aggression.
Published New model allows a computer to understand human emotions



Researchers have developed a model that enables computers to interpret and understand human emotions, utilizing principles of mathematical psychology. In the future, the model can help the computer to adapt its own behavior and guide an irritated or anxious user in different ways. The implications of such technology are profound, offering a glimpse into a future where computers are not merely tools, but empathetic partners in user interaction.
Published The embryo assembles itself



Biological processes depend on puzzle pieces coming together and interacting. Under specific conditions, these interactions can create something new without external input. This is called self-organization, as seen in a school of fish or a flock of birds. Interestingly, the mammalian embryo develops similarly. Scientists now introduce a mathematical framework that analyzes self-organization from a single cell to a multicellular organism.
Published Crucial shift in River Nile's evolution during ancient Egypt discovered



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.
